Release Notes {#RELEASE_NOTES}
=============
Added markdown version of RELEASE_NOTES for evaluation. Modified Doxyfile templates to generate html from the markdown file (assumes doxygen version 1.8+) Added link to release notes to mainpage.doc
2013-05-08 04:54:54 +08:00
More reorganizing of the documentation generated by doxygen. Added a link to the main Unidata netcdf page to the footer, because we are going to turn off the header and footer on the web server. This should allow the Doxygen-generated search field to be properly placed.

Make fillmismatch the default for DAP2 and DAP4 re: https://github.com/Unidata/netcdf-c/issues/1614 NetCDF has a requirement that the type of a _FillValue attribute be the same as the containing variable. However, it is clear that too many servers do not honor this requirement. So, change the default for DAP2 and DAP4 to allow fill mismatch.
2021-01-08 04:17:53 +08:00

Updated release notes to refer to https://github.com/Unidata/netcdf-c/pull/1866
2020-10-17 00:03:48 +08:00
* [Bug Fix] Revert the internal filter code to simplify it. From the user's point of view, the only visible change should be that (1) the functions that convert text to filter specs have had their signature reverted and renamed and have been moved to netcdf_aux.h, and (2) Some filter API functions now return NC_ENOFILTER when inquiry is made about some filter. Internally, the dispatch table has been modified to get rid of the complex structures.
* [Bug Fix] If the HDF5 byte-range Virtual File Driver is available )HDf5 1.10.6 or later) then use it because it has better performance than the one currently built into the netcdf library.
Add fix to release notes.
2020-07-23 02:52:53 +08:00

* [Bug Fix] Now allow szip to be used on variables with unlimited dimension [https://github.com/Unidata/netcdf-c/issues/1774].
This PR adds EXPERIMENTAL support for accessing data in the cloud using a variant of the Zarr protocol and storage format. This enhancement is generically referred to as "NCZarr". The data model supported by NCZarr is netcdf-4 minus the user-defined types and the String type. In this sense it is similar to the CDF-5 data model. More detailed information about enabling and using NCZarr is described in the document NUG/nczarr.md and in a [Unidata Developer's blog entry](https://www.unidata.ucar.edu/blogs/developer/en/entry/overview-of-zarr-support-in). WARNING: this code has had limited testing, so do use this version for production work. Also, performance improvements are ongoing. Note especially the following platform matrix of successful tests: Platform | Build System | S3 support ------------------------------------ Linux+gcc | Automake | yes Linux+gcc | CMake | yes Visual Studio | CMake | no Additionally, and as a consequence of the addition of NCZarr, major changes have been made to the Filter API. NOTE: NCZarr does not yet support filters, but these changes are enablers for that support in the future. Note that it is possible (probable?) that there will be some accidental reversions if the changes here did not correctly mimic the existing filter testing. In any case, previously filter ids and parameters were of type unsigned int. In order to support the more general zarr filter model, this was all converted to char*. The old HDF5-specific, unsigned int operations are still supported but they are wrappers around the new, char* based nc_filterx_XXX functions. This entailed at least the following changes: 1. Added the files libdispatch/dfilterx.c and include/ncfilter.h 2. Some filterx utilities have been moved to libdispatch/daux.c 3. A new entry, "filter_actions" was added to the NCDispatch table and the version bumped. 4. An overly complex set of structs was created to support funnelling all of the filterx operations thru a single dispatch "filter_actions" entry. 5. Move common code to from libhdf5 to libsrc4 so that it is accessible to nczarr. Changes directly related to Zarr: 1. Modified CMakeList.txt and configure.ac to support both C and C++ -- this is in support of S3 support via the awd-sdk libraries. 2. Define a size64_t type to support nczarr. 3. More reworking of libdispatch/dinfermodel.c to support zarr and to regularize the structure of the fragments section of a URL. Changes not directly related to Zarr: 1. Make client-side filter registration be conditional, with default off. 2. Hack include/nc4internal.h to make some flags added by Ed be unique: e.g. NC_CREAT, NC_INDEF, etc. 3. cleanup include/nchttp.h and libdispatch/dhttp.c. 4. Misc. changes to support compiling under Visual Studio including: * Better testing under windows for dirent.h and opendir and closedir. 5. Misc. changes to the oc2 code to support various libcurl CURLOPT flags and to centralize error reporting. 6. By default, suppress the vlen tests that have unfixed memory leaks; add option to enable them. 7. Make part of the nc_test/test_byterange.sh test be contingent on remotetest.unidata.ucar.edu being accessible. Changes Left TO-DO: 1. fix provenance code, it is too HDF5 specific.
2020-06-29 08:02:47 +08:00
* [Enhancement] Add support for cloud storage using a variant of the Zarr storage format. Warning: this feature is highly experimental and is subject to rapid evolution [https://www.unidata.ucar.edu/blogs/developer/en/entry/overview-of-zarr-support-in].
Update release notes
2020-06-26 01:24:57 +08:00
* [Bug Fix] Fix nccopy to properly set default chunking parameters when not otherwise specified. This can significantly improve performance in selected cases. Note that if seeing slow performance with nccopy, then, as a work-around, specifically set the chunking parameters. [https://github.com/Unidata/netcdf-c/issues/1763].
Merge branch 'ncgenchunks.dmh' of https://github.com/DennisHeimbigner/netcdf-c into master

data sections. The problem manifests as incorrect ordering of
data in the created file. Aside from examining the file with
ncdump, the error can be detected by running ncgen with the -lc
flag (to produce a C file). Examine the file to see if any
variable is written in pieces as opposed to a single call to
nc_put_vara. If multiple calls to nc_put_vara are used to write
a variable, then it is probable that the data order is
incorrect. Such multiple writes can occur for large variables
and especially when one of the dimensions is unlimited.
Fix undefined references when using Visual Studio Fix Issue https://github.com/Unidata/netcdf-c/issues/1725. Replace PR https://github.com/Unidata/netcdf-c/pull/1726 Also replace PR https://github.com/Unidata/netcdf-c/pull/1694 The general problem is that under Visual Studio, we are seeing a number of undefined reference and other scoping errors. The reason is that the code is not properly using Visual Studio _declspec() declarations. The basic solution is to ensure that when compiling the code itself one needs to ensure that _declspec(dllexport) is used. There are several sets of macros to handle this, but they all rely on the flag DLL_EXPORT being define when the code is compiled, but not being defined when the code is used via a .h file. As a test, I modified XGetOpt.c to build properly. I also fixed the oc2 library to properly _declspec things like ocdebug. I also made some misc. changes to get all the tests to run if cygwin is installed (to get bash, sed, etc). Misc. Changes: * Put XGetOpt.c into libsrc and copy at build time to the other directories where it is needed.
2020-05-19 09:36:28 +08:00
* [Bug Fix] Add necessary __declspec declarations to allow compilation
of netcdf library without causing errors or (_declspec related)
warnings [https://github.com/Unidata/netcdf-c/issues/1725].
Allow redefinition of variable filters re: Github issue https://github.com/Unidata/netcdf-c/issues/1713 If nc_def_var_filter or nc_def_var_deflate or nc_def_var_szip is called multiple times with the same filter id, but possibly with different sets of parameters, then the first invocation is sticky and later invocations are ignored. The desired behavior is to have the last invocation be used. This PR implements that desired behavior, with some special cases. If you call nc_def_var_deflate multiple times, then the last invocation rule applies with respect to deflate. However, the shuffle filter, if enabled, is always applied just before applying deflate. Misc unrelated changes: 1. Make client-side filters be disabled by default 2. Fix the definition of uintptr_t and use in oc2 and libdap4 3. Add some test cases 4. modify filter order tests to use plugin filters rather than client-side filters
2020-05-11 23:42:31 +08:00
* [Enhancement] When a filter is applied twice with different
parameters, then the second set is used for writing the dataset
[https://github.com/Unidata/netcdf-c/issues/1713].
updated RELEASE_NOTES
2020-05-09 01:03:25 +08:00
* [Bug Fix] Now larger cache settings are used for sequential HDF5 file creates/opens on parallel I/O capable builds; see [Github #1716](https://github.com/Unidata/netcdf-c/issues/1716) for more information.
Update release notes
2020-04-16 05:48:44 +08:00
* [Bug Fix] Add functions to libdispatch/dnotnc4.c to support
dispatch table operations that should work for any dispatch
table, even if they do not do anything; functions such as
nc_inq_var_filter [https://github.com/Unidata/netcdf-c/issues/1693].
Updated release notes.
2020-04-29 05:52:40 +08:00
* [Bug Fix] Fixed a scalar annotation error when scalar == 0; see [Github #1707](https://github.com/Unidata/netcdf-c/issues/1707) for more information.
Use proper CURLOPT values for VERIFYHOST and VERIFYPEER re: https://github.com/Unidata/netcdf-c/issues/1684 re: e-support VZL-904142 Two issues: 1. As of libcurl 7.66, the semantics of CURLOPT_SSL_VERIFYHOST changed so that the non-zero values affects certificate processing. 2. The current library was forcing the values of VERIFYPEER and VERIFYHOST to zero instead of leaving them to the default values. Solution was first to leave the defaults in place for VERIFYPEER and VERIFYHOST as long as they are not set in .ocrc/.dodsrc file. Second, the value of HTTP.SSL.VERIFYPEER or HTTP.SSL.VERIFYHOST as set in .ocrc/.dodrc is used to set the corresponding CURLOPT flags. So for example, adding > HTTP.SSL.VERIFYHOST=2 will set the value of CURLOPT_SSL_VERIFYHOST to 2, the default. Using > HTTP.SSL.VERIFYHOST=0 will set the value of CURLOPT_SSL_VERIFYHOST to 0, which disables it. Similarly for VERIFYPEER. Finally the semantics of HTTP.SSL.VALIDATE is now equivalent to > HTTP.SSL.VERIFYPEER=1 > HTTP.SSL.VERIFYHOST=2
2020-04-11 03:42:27 +08:00
* [Bug Fix] Use proper CURLOPT values for VERIFYHOST and VERIFYPEER; the semantics for VERIFYHOST in particular changed. Documented in NUG/DAP2.md. See [https://github.com/Unidata/netcdf-c/issues/1684].
Corrected an issue with parallel filter test logic in cmake-based builds.
2020-04-02 07:08:24 +08:00

dealing with nc_inq_var_szip(), testing, and release notes
2020-04-08 22:49:04 +08:00
* [Bug Fix] Now allow nc_inq_var_deflate()/nc_inq_var_szip() to be called for all formats, not just HDF5. Non-HDF5 files return NC_NOERR and report no compression in use. This reverts behavior that was changed in the 4.7.4 release. See [https://github.com/Unidata/netcdf-c/issues/1691].
Update RELEASE_NOTES.md
2020-04-07 09:17:42 +08:00

* [Enhancement] Add a dispatch version number to netcdf_meta.h and libnetcdf.settings, in case we decide to change dispatch table in future. See [https://github.com/Unidata/netcdf-c/issues/1469].
* [Bug Fix] Now testing that endianness can only be set on atomic ints and floats. See [https://github.com/Unidata/netcdf-c/issues/1479].
* [Bug Fix] Fix for subtle error involving var and unlimited dim of the same name, but unrelated, in netCDF-4. See [https://github.com/Unidata/netcdf-c/issues/1496].
* [Enhancement] Update for attribute documentation. See [https://github.com/Unidata/netcdf-c/issues/1512].

2019-11-14 22:25:40 +08:00
* [Bug Fix][Enhancement] Corrected assignment of anonymous (a.k.a. phony) dimensions in an HDF5 file. Now when a dataset uses multiple dimensions of the same size, netcdf assumes they are different dimensions. See [GitHub #1484](https://github.com/Unidata/netcdf-c/issues/1484) for more information.

## 4.7.2 - October 22, 2019
Preparing for 4.7.3 development pushed back upstream, forking off to 4.7.2 release branch.
2019-10-19 02:09:28 +08:00
* [Bug Fix][Enhancement] Various bug fixes and enhancements.
Corrects a version typo.
2019-11-21 07:59:18 +08:00
* [Bug Fix][Enhancement] Corrected an issue where protected memory was being written to with some pointer slight-of-hand. This has been in the code for a while, but appears to be caught by the compiler on OSX, under circumstances yet to be completely nailed down. See [GitHub #1486](https://github.com/Unidata/netcdf-c/issues/1486) for more information.
Despite name of the branch, updated RELEASE_NOTES.md not readme.
2019-09-25 02:19:00 +08:00
* [Enhancement] [Parallel IO] Added support for parallel functions in MSVC. See [Github #1492](https://github.com/Unidata/netcdf-c/pull/1492) for more information.
Updated Release Notes.
2019-09-21 04:12:15 +08:00
* [Enhancement] Added a function for changing the ncid of an open file. This function should only be used if you know what you are doing, and is meant to be used primarily with PIO integration. See [GitHub #1483](https://github.com/Unidata/netcdf-c/pull/1483) and [GitHub #1487](https://github.com/Unidata/netcdf-c/pull/1487) for more information.

Merge branch 'master' into byterange.dmh
2019-03-20 02:05:44 +08:00
Reformated release notes to keep style consistent.
2019-08-30 06:32:18 +08:00
* [Enhancement] Added unit_test directory, which contains unit tests for the libdispatch and libsrc4 code (and any other directories that want to put unit tests there). Use --disable-unit-tests to run without unit tests (ex. for code coverage analysis). See [GitHub #1458](https://github.com/Unidata/netcdf-c/issues/1458).
* [Bug Fix] Remove obsolete _CRAYMPP and LOCKNUMREC macros from code. Also brought documentation up to date in man page. These macros were used in ancient times, before modern parallel I/O systems were developed. Programmers interested in parallel I/O should see nc_open_par() and nc_create_par(). See [GitHub #1459](https://github.com/Unidata/netcdf-c/issues/1459).
* [Enhancement] Remove obsolete and deprecated functions nc_set_base_pe() and nc_inq_base_pe() from the dispatch table. (Both functions are still supported in the library, this is an internal change only.) See [GitHub #1468](https://github.com/Unidata/netcdf-c/issues/1468).
* [Bug Fix] Reverted nccopy behavior so that if no -c parameters are given, then any default chunking is left to the netcdf-c library to decide. See [GitHub #1436](https://github.com/Unidata/netcdf-c/issues/1436).

Updated versions, Release Notes.
2019-04-26 05:40:04 +08:00
* [Enhancement] Updated behavior of `pkgconfig` and `nc-config` to allow the use of the `--static` flags, e.g. `nc-config --libs --static`, which will show information for linking against `libnetcdf` statically. See [Github #1360](https://github.com/Unidata/netcdf-c/issues/1360) and [Github #1257](https://github.com/Unidata/netcdf-c/issues/1257) for more information.

Provide byte-range reading of remote datasets re: issue https://github.com/Unidata/netcdf-c/issues/1251 Assume that you have the URL to a remote dataset which is a normal netcdf-3 or netcdf-4 file. This PR allows the netcdf-c to read that dataset's contents as a netcdf file using HTTP byte ranges if the remote server supports byte-range access. Originally, this PR was set up to access Amazon S3 objects, but it can also access other remote datasets such as those provided by a Thredds server via the HTTPServer access protocol. It may also work for other kinds of servers. Note that this is not intended as a true production capability because, as is known, this kind of access to can be quite slow. In addition, the byte-range IO drivers do not currently do any sort of optimization or caching. An additional goal here is to gain some experience with the Amazon S3 REST protocol. This architecture and its use documented in the file docs/byterange.dox. There are currently two test cases: 1. nc_test/tst_s3raw.c - this does a simple open, check format, close cycle for a remote netcdf-3 file and a remote netcdf-4 file. 2. nc_test/test_s3raw.sh - this uses ncdump to investigate some remote datasets. This PR also incorporates significantly changed model inference code (see the superceded PR https://github.com/Unidata/netcdf-c/pull/1259). 1. It centralizes the code that infers the dispatcher. 2. It adds support for byte-range URLs Other changes: 1. NC_HDF5_finalize was not being properly called by nc_finalize(). 2. Fix minor bug in ncgen3.l 3. fix memory leak in nc4info.c 4. add code to walk the .daprc triples and to replace protocol= fragment tag with a more general mode= tag. Final Note: Th inference code is still way too complicated. We need to move to the validfile() model used by netcdf Java, where each dispatcher is asked if it can process the file. This decentralizes the inference code. This will be done after all the major new dispatchers (PIO, Zarr, etc) have been implemented.

2018-10-23 06:52:07 +08:00
* [Bug Fix] The use of NC_DISKLESS has been modified to make it cleaner. This adds a new flag called NC_PERSIST that takes over the now obsolete NC_MPIPOSIX.
Revert/Improve nc_create + NC_DISKLESS behavior re: https://github.com/Unidata/netcdf-c/issues/1154 Inadvertently, the behavior of NC_DISKLESS with nc_create() was changed in release 4.6.1. Previously, the NC_WRITE flag needed to be explicitly used with NC_DISKLESS in order to cause the created file to be persisted to disk. Additional analyis indicated that the current NC_DISKLESS implementation was seriously flawed. This PR attempts to clean up and regularize the situation with respect to NC_DISKLESS control. One important aspect of diskless operation is that there are two different notions of write. 1. The file is read-write vs read-only when using the netcdf API. 2. The file is persisted or not to disk at nc_close(). Previously, these two were conflated. The rules now are as follows. 1. NC_DISKLESS + NC_WRITE means that the file is read/write using the netcdf API 2. NC_DISKLESS + NC_PERSIST means that the file is persisted to a disk file at nc_close. 3. NC_DISKLESS + NC_PERSIST + NC_WRITE means both 1 and 2. The NC_PERSIST flag is new and takes over the obsolete NC_MPIPOSIX flag. NC_MPIPOSIX is still defined, but is now an alias for the NC_MPIIO flag. It is also now the case that for netcdf-4, NC_DISKLESS is independent of NC_INMEMORY and in fact it is an error to specify both flags simultaneously. Finally, the MMAP code was fixed to use NC_PERSIST as well. Also marked MMAP as deprecated. Also added a test case to test various combinations of NC_DISKLESS, NC_PERSIST, and NC_WRITE. This PR affects a number of files and especially test cases that used NC_DISKLESS. Misc. Unrelated fixes 1. fixed some warnings in ncdump/dumplib.c
2018-10-11 03:32:17 +08:00
* [Obsolete] Obsolete the MPIPOSIX flag.

* [Bug Fix] When using filters with HDF5 1.10.x or later, it is necessary to utilize the HDF5 replacements for malloc, realloc, and free in the filter code.
## 4.6.2-rc1 - September 19, 2018
There was a request to extend the provenance information stored in the _NCProperties attribute to allow two things: 1. capture of additional library dependencies (over and above hdf5) 2. Recognition of non-netcdf libraries that create netcdf-4 format files. To this end, the _NCProperties format has been extended to be and arbitrary set of key=value pairs separated by commas. This new format has version = 2, and uses commas as the pair separator. Thus the general form is: _NCProperties = "version=2,key1=value,key2=value2..." ; This new version is accompanied by a new ./configure option of the form --with-ncproperties="key1=value1,key2=value2..." that specifies pairs to add to the _NCProperties attribute for all files created with that netcdf library. At this point, what is missing is some programmatic way to specify either all the pairs or additional pairs to the _NCProperties attribute. Not sure of the best way to do this. Builders using non-netcdf libraries can specify whatever they want in the key value pairs (as long as the version=2 is specified first). By convention, the primary library is expected to be the the first pair after the leading version=2 pair, but this is convention only and is neither required nor enforced. Related changes: 1. Fixed the tests that check _NCProperties to properly operate with version=2. 2. When reading a version 1 _NCProperties attribute, convert it to look like a version 2 attribute. 2. Added some version 2 tests to ncdump/tst_fileinfo.c and ncdump/tst_fileinfo.sh Misc Changes: 1. Fix minor problem in ncdap_test/testurl.sh where a parameter to buildurl needed to be quoted. 2. Minor fix to ncgen to swap switches -H and -h to be consistent with other utilities. 3. Document the -M flag in nccopy usage() and the nccopy man page. 4. Modify a test case to use the nccopy -M flag.
2018-08-26 11:44:41 +08:00
* [Enhancement] Create a new version of _NCProperties provenance attribute. This version (version 2) supports arbitrary key-value pairs. It is the default when new files are created. Version 1 continues to be accepted.
Add the ability to set some additional curlopt values Add the ability to set some additional curlopt values via .daprc (aka .dodsrc). This effects both DAP2 and DAP4 protocols. Related issues: [1] re: esupport: KOZ-821332 [2] re: github issue https://github.com/Unidata/netcdf4-python/issues/836 [3] re: github issue https://github.com/Unidata/netcdf-c/issues/1074 1. CURLOPT_BUFFERSIZE: Relevant to [1]. Allow user to set the read/write buffersizes used by curl. This is done by adding the following to .daprc (aka .dodsrc): HTTP.READ.BUFFERSIZE=n where n is the buffersize in bytes. There is a built-in (to curl) limit of 512k for this value. 2. CURLOPT_TCP_KEEPALIVE (and CURLOPT_TCP_KEEPIDLE and CURLOPT_TCP_KEEPINTVL): Relevant (maybe) to [2] and [3]. Allow the user to turn on KEEPALIVE This is done by adding the following to .daprc (aka .dodsrc): HTTP.KEEPALIVE=on|n/m If the value is "on", then simply enable default KEEPALIVE. If the value is n/m, then enable KEEPALIVE and set KEEPIDLE to n and KEEPINTVL to m.
2018-08-27 07:04:46 +08:00
* [Enhancement] Allow user to set http read buffersize for DAP2 and DAP4 using the tag HTTP.READ.BUFFERSIZE in the .daprc file.
* [Enhancement] Allow user to set http keepalive for DAP2 and DAP4 using the tag HTTP.KEEPALIVE in the .daprc file (see the OPeNDAP documentation for details).
The Jetstream remote test server is now working. So it now becomes the first default test server to try. This also means that the dap4 remote testing is enabled. The only issue to watch is to see if the jetstream-based server can stay up for significant periods of time. A uptimerobot (https://uptimerobot.com) has been set ups to monitor this hourly, so we shall see.
2018-06-27 03:58:45 +08:00
* [Enhancement] Support DAP4 remote tests using a new remote test server locatedon the Unidata JetStream project.
Re-Implement the nc_get/put_vars operations for netcdf-4 using the corresponding HDF5 operations. re: github issue https://github.com/Unidata/netcdf-c/issues/908 also in reference to https://github.com/pydata/xarray/issues/2004 The netcdf-c library has implemented the nc_get_vars and nc_put_vars operations as element at a time. This has resulted in very slow operation. This pr attempts to improve the situation for netcdf-4/hdf5 files by using the slab operations provided by the hdf5 library. The new implementation passes the get/put vars stride information down to the hdf5 slab operations. The result appears to improve performance significantly. Some simple tests on large 2-D arrays shows speedups in excess of 150. Misc. other changes: 1. fix bug in ncgen/semantics.c; using a list's allocated length instead of actual length. 2. Added a temporary hook in the netcdf library plus a performance test case (tst_varsperf.c) to estimate the speedup. After users have had some experience with this, I will remove it, probably after the 4.7 release.
2018-05-23 06:50:52 +08:00
* [Enhancement] Improved the performance of the nc_get/put_vars operations by using the equivalent slab capabilities of hdf5. Result is a significant speedup of these operations. See [GitHub #1001](https://github.com/Unidata/netcdf-c/pull/1001) for more information.

* [Enhancement] Added an option to enable strict null-byte padding for headers; this padding was specified in the spec but was not enforced. Enabling this option will allow you to check your files, as it will return an E_NULLPAD error. It is possible for these files to have been written by older versions of libnetcdf. There is no effective problem caused by this lack of null padding, so enabling these options is informational only. The options for `configure` and `cmake` are `--enable-strict-null-byte-header-padding` and `-DENABLE_STRICT_NULL_BYTE_HEADER_PADDING`, respectively. See [Github #657](https://github.com/Unidata/netcdf-c/issues/657) for more information.
Updated release notes.

### 4.5.0-rc3 - September 29, 2017
Updated release notes.
2017-09-28 02:01:32 +08:00
* [Update] Due to ongoing issues, native CDF5 support has been disabled by **default**. You can use the options mentioned below (`--enable-cdf5` or `-DENABLE_CDF5=TRUE` for `configure` or `cmake`, respectively). Just be aware that for the time being, Reading/Writing CDF5 files on 32-bit platforms may result in unexpected behavior when using extremely large variables. For 32-bit platforms it is best to continue using `NC_FORMAT_64BIT_OFFSET`.

### 4.5.0-rc1 - June 5, 2017
updated release notes.
2016-11-22 06:15:07 +08:00
Primary change: add dap4 support Specific changes: 1. Add dap4 code: libdap4 and dap4_test. Note that until the d4ts server problem is solved, dap4 is turned off. 2. Modify various files to support dap4 flags: configure.ac, Makefile.am, CMakeLists.txt, etc. 3. Add nc_test/test_common.sh. This centralizes the handling of the locations of various things in the build tree: e.g. where is ncgen.exe located. See nc_test/test_common.sh for details. 4. Modify .sh files to use test_common.sh 5. Obsolete separate oc2 by moving it to be part of netcdf-c. This means replacing code with netcdf-c equivalents. 5. Add --with-testserver to configure.ac to allow override of the servers to be used for --enable-dap-remote-tests. 6. There were multiple versions of nctypealignment code. Try to centralize in libdispatch/doffset.c and include/ncoffsets.h 7. Add a unit test for the ncuri code because of its complexity. 8. Move the findserver code out of libdispatch and into a separate, self contained program in ncdap_test and dap4_test. 9. Move the dispatch header files (nc{3,4}dispatch.h) to .../include because they are now shared by modules. 10. Revamp the handling of TOPSRCDIR and TOPBUILDDIR for shell scripts. 11. Make use of MREMAP if available 12. Misc. minor changes e.g. - #include <config.h> -> #include "config.h" - Add some no-install headers to /include - extern -> EXTERNL and vice versa as needed - misc header cleanup - clean up checking for misc. unix vs microsoft functions 13. Change copyright decls in some files to point to LICENSE file. 14. Add notes to RELEASENOTES.md
2017-03-09 08:01:10 +08:00
* [Enhancement] DAP4 is now included. Since dap2 is the default for urls, dap4 must be specified by

Updated release notes.
2016-07-28 04:14:32 +08:00
Updated release notes for https://github.com/Unidata/netcdf-c/issues/323
2016-11-19 04:30:13 +08:00
* [Bug] Fixed an issue where `ncgen` would potentially crash or write incorrect netCDF4 binary data under very specific circumstances. This bug did *not* affect data written on 32-bit systems or by using the netCDF library; it was specific to `ncgen`. This would only happen when writing a compound data type containing an 8-byte data type followed by a 4-byte data type *and* the 4-byte data type was not properly aligned; this would *possibly* result in incorrect padding. This did not affect 32-bit systems, or data written directly by the library. See [GitHub #323](https://github.com/Unidata/netcdf-c/issues/323) for more information.
Updated documentation to reflect DAP2 reserved keywords. See https://github.com/Unidata/netcdf-c/issues/308 for more info.
2016-09-20 05:36:50 +08:00
* [Documentation] Updated documentation related to netCDF variable names and DAP2 access to reflect the undefined behavior potentially observed when DAP2 reserved keywords are used as netCDF variable names. See [GitHub #308](https://github.com/Unidata/netcdf-c/issues/308) for more information.
Corrected an issue reported in https://github.com/Unidata/netcdf-c/issues/317
2016-09-14 03:55:33 +08:00
* [Bug] Fixed an issue with `nc_inq_type()` not returning proper value in some circumstances. See [GitHub #317](https://github.com/Unidata/netcdf-c/issues/317) for more information.
Updated release notes.
2016-09-01 05:53:12 +08:00
* [Bug] Corrected an issue related to test failures when `--disable-utilities` or `-DENABLE_UTILITIES=OFF` are specified when building with autotools or cmake, respectively. See [GitHub #313](https://github.com/Unidata/netcdf-c/issues/313) for more information.
Updated release notes to reference https://github.com/Unidata/netcdf-c/issues/gh300.dmh and https://github.com/Unidata/netcdf-c/pull/301
2016-08-10 03:37:10 +08:00
* [Bug][Enhancement] Corrected a behavioral issue with the `_NCProperties` attribute taking up too much space. See [GitHub #300](https://github.com/Unidata/netcdf-c/issues/300) and [GitHub #301](https://github.com/Unidata/netcdf-c/pull/301) for more information.
Updated release notes.
2016-07-28 04:14:32 +08:00
* [Bug] Corrected behavior for `nc-config` so that, if `nf-config` is found in system, the proper fortran-related information will be conveyed. See [GitHub #296](https://github.com/Unidata/netcdf-c/issues/296] for more information.
Added some notes to release notes.
2016-06-29 03:23:14 +08:00
## 4.4.1 - June 28, 2016
* [File Change] Starting with release 4.4.1, netCDF-4 files created will have superblock version 0 instead of superblock version 2, as was observed in previous netCDF versions. This is due to a workaround required to avoid backwards binary incompatibility when using libhdf5 1.10.x or greater. Superblock versions 0 and 2 appear to be forward and backward compatible. Other than a different superblock number the data should remain consistent.
Added a link to https://github.com/Unidata/netcdf-c/pull/279 in Release notes.
2016-06-28 05:12:31 +08:00
* [Enhancement] Added better error reporting when ncdump/nccopy are given a bad constraint in a DAP url. See [GitHub #279](https://github.com/Unidata/netcdf-c/pull/279) for more information.
Updated release notes in preparation for the third release candidate.

2016-05-14 01:48:49 +08:00
### 4.4.1-RC2 - May 13, 2016
* [Enhancement] Added provenance information to files created. This information consists of a persistent attribute named `_NCProperties` plus two computed attributes, `_IsNetcdf4` and `_SuperblockVersion`. Associated documentation was added to the file `docs/attribute_conventions.md`. See [GitHub pull request #260](https://github.com/Unidata/netcdf-c/pull/260) for more information.
* [Bug Fix] Cleaned up some dead links in the doxygen-generated documentation.
* [Bug Fix] Corrected several issues related to building under Visual Studio 2014.
* [Bug Fix] Corrected several test failures related to HDF5 `1.10.0`

2016-04-11 23:35:00 +08:00
Updated release notes with reference to https://github.com/Unidata/netcdf-c/issues/250
2016-04-11 23:15:16 +08:00
* [Bug Fix][Enhancement] Fixed an issue with netCDF4 files generated using version `1.10.0` of the HDF5 library. The 1.10 release potentially changed the underlying file format, introducing a backwards compatibility issue with the files generated. HDF5 provided an API for retaining the 1.8.x file format, which is now on by default. See [GitHub Issue #250](https://github.com/Unidata/netcdf-c/issues/250) for more information.
Updated release notes in support of https://github.com/Unidata/netcdf-c/issues/242
2016-04-05 05:29:44 +08:00
* [Bug Fix] Corrected an issue with autotools-based builds performed out-of-source-tree. See [GitHub Issue #242](https://github.com/Unidata/netcdf-c/issues/242) for more information.
Artificial bump to ping travis-ci.
2016-04-06 05:55:53 +08:00
* [Enhancement] Modified `nc_inq_type()` so that it would work more broadly without requiring a valid ncid. See [GitHub Issue #240](https://github.com/Unidata/netcdf-c/issues/240) for more information.
Updated release notes in support of https://github.com/Unidata/netcdf-c/issues/242
2016-04-05 05:29:44 +08:00
* [Enhancement] Accepted a patch code which added a hashmap lookup for rapid var and dim retrieval in nc3 files, contributed by Greg Sjaardema. See [GitHub Pull Request #238](https://github.com/Unidata/netcdf-c/pull/238) for more information.
* [Bug Fix] Accepted a contributed pull request which corrected an issue with how the cmake-generated `nc-config` file determined the location of installed files. See [GitHub Pull Request #235](https://github.com/Unidata/netcdf-c/pull/235) for more information.
* [Enhancement] Added an advanced option for CMake-based builds, `ENABLE_SHARED_LIBRARY_VERSION`. This option is `ON` by default, but if turned off, only `libnetcdf.dylib` will be generated, instead of files containing the SOVERSION in the file name. This is a requested feature most people might not care about. See [GitHub #228](https://github.com/Unidata/netcdf-c/issues/228) for more information.
* [Bug Fix] Corrected an issue with duplicated error codes defined in multiple header files. See [GitHub #213](https://github.com/Unidata/netcdf-c/issues/213) for more information.
* [Bug Fix] Addressed an issue specific to Visual Studio 2015 on Windows. On very large files, some calls to the `fstat` class of functions would fail for no apparent reason. This behavior was **not** observed under Visual Studio 2013. This has now been mitigated. See [GitHub #188](https://github.com/Unidata/netcdf-c/issues/188) for more information.
* [Enhancement] Updated `nc-config` to report whether `logging` is enabled in netcdf. Additionally, if `f03` is available in an installed netcdf-fortran library, it will now be reported as well.
* [Bug Fix] Addressed an issue where `netcdf_mem.h` was not being installed by cmake. See [GitHub #227](https://github.com/Unidata/netcdf-c/issues/227) for more information.
* [Bug Fix] Addressed an issue where `ncdump` would crash when trying to read a netcdf file containing an empty ragged `VLEN` variable in an unlimited dimension. See [GitHub #221](https://github.com/Unidata/netcdf-c/issues/221) for more information.

## 4.4.0 Released - January 13, 2016
Updated RELEASE_NOTES.
2015-05-16 05:49:23 +08:00
Updated release notes re: bump in SO version.
2016-01-12 06:29:24 +08:00
* Bumped SO version to 11.0.0.
Updated release notes.
2016-01-09 04:09:00 +08:00
* Modified `CMakeLists.txt` to work with the re-organized cmake configuration used by the latest HDF5, `1.8.16`, on Windows. Before this fix, netCDF would fail to locate hdf5 1.8.16 when using cmake on Windows. See [GitHub #186](https://github.com/Unidata/netcdf-c/issues/186) for more information.
Cleanup prior to merge, added a reference to github issue http://github.com/Unidata/netcdf-c/issues/181 to the release notes.
2016-01-01 05:28:59 +08:00
* Addressed an issue with `ncdump` when annotations were used. The indices for the last row suffered from an off-by-1 error. See [GitHub issue #181](https://github.com/Unidata/netcdf-c/issues/181) for more information.
Merging from master in preparation for merging branch back into main development branch.
2015-12-31 04:00:12 +08:00
Updated release notes with information regarding https://github.com/Unidata/netcdf-c/issues/159.
2015-12-29 07:10:31 +08:00
* Addressed an issue on platforms where `char` is `unsigned` by default (such as `ARM`), as well as an issue describing regarding undefined behavior, again on `ARM`. See [GitHub issue #159](https://github.com/Unidata/netcdf-c/issues/159) for detailed information.
Added reference to https://github.com/Unidata/netcdf-c/issues/178 in Release Notes.
2015-12-29 07:20:54 +08:00
* Fixed an ambiguity in the grammar for cdl files. See [GitHub #178](https://github.com/Unidata/netcdf-c/issues/178) for more information.
Addressed github issue https://github.com/Unidata/netcdf-c/issues/171
2015-12-09 06:06:30 +08:00
* Updated documentation for `nc_get_att_string()` to reflect the fact that it returns allocated memory which must be explicitly free'd using `nc_free_string()`. Reported by Constantine Khroulev, see [GitHub Issue 171](https://github.com/Unidata/netcdf-c/issues/171) for more information.

* Modified ncgen to properly handle the L and UL suffixes for integer constants
to keep backward compatibility. Now it is the case the single L suffix
(e.g. 111L) is treated as a 32 bit integer. This makes it consistent with
the fact that NC_LONG (netcdf.h) is an alias for NC_INT. Existing .cdl
files should be examined for occurrences of the L prefix to ensure that
this change will not affect them.
(see Github issue 156[https://github.com/Unidata/netcdf-c/issues/156]).
Updated Release notes.
2015-11-17 05:39:02 +08:00
* Updated documentation to reference the new `NodeJS` interface to netcdf4, by Sven Willner. It is available from [https://www.npmjs.com/package/netcdf4](https://www.npmjs.com/package/netcdf4) or from the GitHub repository at [https://github.com/swillner/netcdf4-js](https://github.com/swillner/netcdf4-js).
Updated release notes describing https://github.com/Unidata/netcdf-c/pull/150
2015-11-13 06:17:52 +08:00
* Incorporated pull request https://github.com/Unidata/netcdf-c/pull/150 from Greg Sjaardema to remove the internal hard-wired use of `NC_MAX_DIMS`, instead using a dynamic memory allocation.
Updated Release notes.

* Added CDM-5 support via new mode flag called NC_64BIT_DATA (alias NC_CDF5).
A bit of refactoring of the release notes to make it render nicely by Doxygen and some markdown editors.
2015-10-16 01:35:18 +08:00
Major kudos to Wei-Keng Liao for all the effort he put into getting this to work.
Updated in-code documentation.
2015-10-16 01:29:51 +08:00
This cascaded into a number of other changes.
Resolve merge conflict.
2016-01-05 05:22:26 +08:00
Use PnetCDF instead of parallel-netcdf to avoid confusion with parallel netcdf4. Also, update PnetCDF web page.
2018-09-18 00:47:40 +08:00
1. Renamed libsrcp5 -> libsrcp because PnetCDF can do parallel io for CDF-1, CDF-2 and CDF-5, not just CDF-5.
A bit of refactoring of the release notes to make it render nicely by Doxygen and some markdown editors.
2015-10-16 01:35:18 +08:00
2. Given #1, then the NC_PNETCDF mode flag becomes a subset of NC_MPIIO, so made NC_PNETCDF an alias for NC_MPII.
3. NC_FORMAT_64BIT is now deprecated. Use NC_FORMAT_64BIT_OFFSET.

Updated release notes for 4.4.0 RC4.
2015-11-11 05:28:36 +08:00
* Deprecating various extended format flags.
The various extended format flags of the format `NC_FORMAT_FOO` have been refactored into the form `NC_FORMATX_FOO`. The old flags still exist but have been marked as deprecated and will be removed at some point. This was done to avoid confusion between the extended format flags and the format flags `NC_FORMAT_CLASSIC`, `NC_FORMAT_64BIT_OFFSET`, etc. The mapping of deprecated-to-new flags is as follows:
Deprecated | Replaced with
-----------|-------------
NC\_FORMAT\_NC3 | NC\_FORMATX\_NC3
NC\_FORMAT\_NC\_HDF5 | NC\_FORMATX\_NC\_HDF5
NC\_FORMAT\_NC4 | NC\_FORMATX\_NC4
NC\_FORMAT\_NC\_HDF4 | NC\_FORMATX\_NC\_HDF4
NC\_FORMAT\_PNETCDF | NC\_FORMATX\_PNETCDF

NC\_FORMAT\_UNDEFINED | NC\_FORMATX\_UNDEFINED
Made a comment in the release notes re: new minimum cmake version. See https://github.com/Unidata/netcdf-c/issues/135 for more information.
2015-10-21 00:55:08 +08:00
* Reduced minimum cmake version to `2.8.11` from `2.8.12`. This will allow for cmake use on a broader set of popular linux platforms without having to do a custom cmake install. See https://github.com/Unidata/netcdf-c/issues/135 for more information.
Additional dead link modification.
2016-01-16 05:39:32 +08:00
* The documentation section `The Default Chunking Scheme` has been updated with more information. This lives in the `guide.dox` file in the `docs/` directory, or can be found online in the appropriate location (typically http://www.unidata.ucar.edu/netcdf/docs/), once this release has been published.

2015-07-23 03:28:16 +08:00
Added notes related to [NCF-338] to README.md
2015-07-28 05:37:54 +08:00
* Addressed an inefficiency in how bytes would be swapped when converting between `LITTLE` and `BIG` ENDIANNESS. See [NCF-338](https://bugtracking.unidata.ucar.edu/browse/NCF-338) for more information.

2015-07-23 03:28:16 +08:00
* Addressed an issue where an interrupted read on a `POSIX` system would return an error even if errno had been properly set to `EINTR`. This issue was initially reported by David Knaak at Cray. More information may be found at [NCF-337](https://bugtracking.unidata.ucar.edu/browse/NCF-337).

* Added a note to the install directions pointing out that parallel make
cannot be used for 'make check'.
Updated release notes in preparation for next release candidate.
2015-07-10 01:00:31 +08:00
### 4.4.0-RC2 Released 2015-07-09
* Minor bug fixes and cleanup of issues reported with first release candidate.
### 4.4.0-RC1 Released 2015-06-09
Addressed conflict between master, mem2.
2015-06-03 05:03:12 +08:00
Updated release notes to reflect change in pre-built binary version.
2015-06-05 05:46:37 +08:00
* The pre-built Windows binaries are now built using `Visual Studio 2012`, instead of `Visual Studio 2010`. Source-code compilation remains function with `Visual Studio 2010`, this is just a change in the pre-built binaries.
* Added support for opening in-memory file content. See `include/netcdf_mem.h` for the procedure signature. Basically, it allows one to fill a chunk of memory with the equivalent of some netCDF file and then open it and read from it as if it were any other file. See [NCF-328](https://bugtracking.unidata.ucar.edu/browse/NCF-328) for more information.
Added information re: [NCF-332] to release notes.

* Addressed an issue when reading hdf4 files with explicit little-endian datatypes. This issue was [reported by Tim Burgess at GitHub](https://github.com/Unidata/netcdf-c/issues/113). See [NCF-332](https://bugtracking.unidata.ucar.edu/browse/NCF-332) for more information.
1. fix nc_open_mem doxygen description 2. fix some bugs wrt to cygwin vs linux. 3. add to RELEASE_NOTES 4. try to fix tst_inmemory fd error by putting the first arg to dotest in quotes.
2015-05-29 09:23:33 +08:00
Updated release notes.
2015-05-21 01:13:33 +08:00
* Addressed an issue with IBM's `XL C` compiler on AIX and how it handled some calls to malloc. Also, as suggested by Wolfgang Hayek, developers using this compiler may need to pass `CPPFLAGS=-D_LINUX_SOURCE_COMPAT` to avoid some test failures.
Updated RELEASE_NOTES.
2015-05-16 05:49:23 +08:00
* Addressed an issure in netcdf4 related to specifying an endianness explicitly. When specifying an endianness for `NC_FLOAT`, the value would appear to not be written to file, if checked with `ncdump -s`. The issue was more subtle; the value would be written but was not being read from file properly for non-`NC_INT`. See [GitHub Issue](https://github.com/Unidata/netcdf-c/issues/112) or [NCF-331](https://bugtracking.unidata.ucar.edu/browse/NCF-331) for more information.
Updated RELEASE_NOTES with information re: [NCF-330].
2015-05-09 03:49:18 +08:00
* Addressed an issue in netcdf4 on Windows w/DAP related to how byte values were copied with sscanf. Issue originally reported by Ellen Johnson at Mathworks, see [NCF-330](https://bugtracking.unidata.ucar.edu/browse/NCF-330) for more information.

2014-09-30 04:15:45 +08:00
Updated release notes
2015-01-15 05:19:00 +08:00
* Added functionality to make it easier to build `netcdf-fortran` as part of the `netcdf-c` build for *NON-MSVC* builds. This functionality is enabled at configure time by using the following **Highly Experimental** options:
Renamed option used to enable fortran bootstrap behavior. Updated RELEASE_NOTES.md with information re: this new option.

Enabling these options creates two new make targets:
* `build-netcdf-fortran`
* `install-netcdf-fortran`
Example Work Flow from netcdf-c source directory:
* $ `./configure --enable-remote-fortran-bootstrap --prefix=$HOME/local`
* $ `make check`
* $ `make install`
* $ `make build-netcdf-fortran`
* $ `make install-netcdf-fortran`
Renamed option used to enable fortran bootstrap behavior. Updated RELEASE_NOTES.md with information re: this new option.

Cleaned up RELEASE_NOTES document for rendering by doxygen.
2015-01-15 04:20:51 +08:00
> These make targets are **only** valid after `make install` has been invoked. This cannot be enforced rigidly in the makefile for reasons we will expand on in the documentation, but in short: `make install` may require sudo, but using sudo will discard environmental variables required when attempting to build netcdf-fortran in this manner.<br><br>
Further reorganization. Figured out how subpage works with different files. Renamed some of the header cells.
2014-12-10 07:36:15 +08:00
Cleaned up RELEASE_NOTES document for rendering by doxygen.
2015-01-15 04:20:51 +08:00
> It is important to note that this is functionality is for *convenience only*. It will remain possible to build `netcdf-c` and `netcdf-fortran` manually. These make targets should hopefully suffice for the majority of our users, but for corner cases it may still be required of the user to perform a manual build.

* Added a failure state if the `m4` utility is not found on non-Windows systems; previously, the build would fail when it reached the point of invoking m4.
* Added an explicit check in the build systems (autotools, cmake) for the CURL-related option `CURLOPT_CHUNK_BGN_FUNCTION`. This option was introduced in libcurl version `7.21.0`. On installations which require libcurl and have this version, `CURLOPT_CHUNK_BGN_FUNCTION` will be available. Otherwise, it will not.
Renamed option used to enable fortran bootstrap behavior. Updated RELEASE_NOTES.md with information re: this new option.
2014-11-21 06:56:11 +08:00
Use PnetCDF instead of parallel-netcdf to avoid confusion with parallel netcdf4. Also, update PnetCDF web page.
2018-09-18 00:47:40 +08:00
* The PnetCDF support was not properly being used to provide mpi parallel io for netcdf-3 classic files. The wrong dispatch table was being used. [NCF-319](https://bugtracking.unidata.ucar.edu/browse/NCF-319)
Renamed option used to enable fortran bootstrap behavior. Updated RELEASE_NOTES.md with information re: this new option.
2014-11-21 06:56:11 +08:00
Added missing release notes entries.
2015-01-26 08:29:43 +08:00
* In nccopy utility, provided proper default for unlimited dimension in chunk-size specification instead of requiring explicit chunk size. Added associated test. [NCF-321](https://bugtracking.unidata.ucar.edu/browse/NCF-321)
* Fixed documentation typo in FILL_DOUBLE definition in classic format specification grammar. Fixed other typos and inconsistencies in Doxygen version of User Guide.
* For nccopy and ncgen, added numeric options (-3, -4, -6, -7) for output format, to provide less confusing format version specifications than the error-prone equivalent -k options (-k1, -k2, -k3, -k4). The new numeric options are compatible with NCO's mnemonic version options. The old -k numeric options will still be accepted but are deprecated, due to easy confusion between format numbers and format names. [NCF-314](https://bugtracking.unidata.ucar.edu/browse/NCF-314)
Renamed option used to enable fortran bootstrap behavior. Updated RELEASE_NOTES.md with information re: this new option.
2014-11-21 06:56:11 +08:00
* Fixed bug in ncgen. When classic format was in force (k=1 or k=4), the "long" datatype should be treated as int32. Was returning an error. [NCF-318](https://bugtracking.unidata.ucar.edu/browse/NCF-318)
* Fixed bug where if the netCDF-C library is built with the HDF5 library but without the HDF4 library and one attempts to open an HDF4 file, an abort occurs rather than returning a proper error code (NC_ENOTNC). [NCF-317](https://bugtracking.unidata.ucar.edu/browse/NCF-317)
re: NCF-317 If the netCDF-C library is built with the HDF5 library but without the HDF4 library and one attempts to open an HDF4 file, an abort occurs rather than returning a proper error code (NC_ENOTNC). Fix is to modify dfile.c#NC_check_file_type to properly #ifdef relevant tests.
2014-10-08 02:37:41 +08:00
Updated RELEASE_NOTES with additional information re: NC_EXTRA_DEPS.
2014-09-30 04:15:45 +08:00
* Added a new option, `NC_EXTRA_DEPS`, for cmake-based builds. This is analogous to `LIBS` in autotools-based builds. Example usage:
$ cmake .. -NC_EXTRA_DEPS="-lcustom_lib"
More details may be found at the Unidata JIRA Dashboard. [NCF-316](https://bugtracking.unidata.ucar.edu/browse/NCF-316)

### 4.3.3-rc2 Released 2014-09-24
Updated the RELEASE NOTES, bumped to the next (possible) version, rc2. It's not for sure that there will be an RC2, however.
2014-08-30 02:24:16 +08:00
Update release notes for NCF-309
2014-09-19 08:45:59 +08:00
* Fixed the code for handling character constants
in datalists in ncgen. Two of the problems were:
1. It failed on large constants
2. It did not handle e.g. var = 'a', 'b', ...
in the same way that ncgen3 did.
See [NCF-309](https://bugtracking.unidata.ucar.edu/browse/NCF-309).
Removed stray warning from RELEASE_NOTES.md
2014-12-09 04:29:26 +08:00
* Added a new file, `netcdf_meta.h`. This file is generated automatically at configure time and contains information related to the capabilities of the netcdf library. This file may be used by projects dependent upon `netcdf` to make decisions during configuration, based on how the `netcdf` library was built. The macro `NC_HAVE_META_H` is defined in `netcdf.h`. Paired with judicious use of `ifdef`'s, this macro will indicate to developers whether or not the meta-header file is present. See [NCF-313](https://bugtracking.unidata.ucar.edu/browse/NCF-313).
Updated RELEASE_NOTES file with information about meta header.
2014-09-12 05:30:36 +08:00
Added a new .gitignore specific to include/. Added netcdf_meta.h to user documentation generated by doxygen.
2014-09-19 05:05:08 +08:00
> Determining the presence of `netcdf_meta.h` can also be accomplished by methods common to autotools and cmake-based build systems.
Updated RELEASE_NOTES file with information about meta header.
2014-09-12 05:30:36 +08:00
Updated release notes re: server based search.
2014-09-25 02:34:38 +08:00
* Changed `Doxygen`-generated documentation hosted by Unidata to use more robust server-based searching.
Fixed incorrect URLs with page anchors as reported by Russ.
2014-09-11 03:32:49 +08:00

2014-08-30 02:24:16 +08:00
Updated with information re: pending 4.3.3 RC.
2014-08-26 01:03:35 +08:00
### 4.3.3-rc1 Released 2014-08-25
Bumped developer revision to 4.3.3-rc1, to avoid any confusion as to what version a change belongs to.
2014-04-24 06:00:49 +08:00
Manually merging pull request https://github.com/Unidata/netcdf-c/pull/74 contributed by Nico Schlömer
2014-08-21 02:30:11 +08:00
* Added `CMake`-based export files, contributed by Nico Schlömer. See https://github.com/Unidata/netcdf-c/pull/74.
Added missing release notes entries.
2015-01-26 08:29:43 +08:00
* Documented that ncgen input can come from standard input.
* Regularized generation of libnetcdf.settings file to make parsing it easier.
Fixed bug NCF-310 (ncdump char vars with multiple unlimited dims). Added associated tests and entry in RELEASE_NOTES.
2014-08-08 02:49:36 +08:00
* Fixed ncdump bug for char variables with multiple unlimited dimensions and added an associated test. Now the output CDL properly disambiguates dimension groupings, so that ncgen can generate the original file from the CDL. [NCF-310](https://bugtracking.unidata.ucar.edu/browse/NCF-310)
Changed overall color scheme of developer-level documentation to a light-red color. Also renamed Doxygen configuration used to generate developer documentation. This will make it obvious at a glance whether somebody is reading the user documentation or developer documentation.
2014-07-31 04:23:27 +08:00
* Converted the [Manually-maintained FAQ page](http://www.unidata.ucar.edu/software/netcdf/docs/faq.html) into markdown and added it to the `docs/` directory. This way the html version will be generated when the rest of the documentation is built, the FAQ will be under version control, and it will be in a more visible location, hopefully making it easier to maintain.
Made a note in RELEASE_NOTES about the updated cmake version requirement.
2014-07-16 00:52:24 +08:00
* Bumped minimum required version of `cmake` to `2.8.12`. This was necessitated by the adoption of the new `CMAKE_MACOSX_RPATH` property, for use on OSX.
JIRA: NCF-308 Jennifer Adams has requested a reversion in behavior so that all dap requests include a constraint. Problem is caused by change in prefetch where if all variables are requested, then no constraint is generated. Fix is to always generate a constraint in prefetch.

Cleaning up Doxygen warnings, reorganization of top-level documentation.
2014-07-15 06:56:42 +08:00
* Added a new option for cmake-based builds, `ENABLE_DOXYGEN_LATEX_OUTPUT`. On those systems with `make` and `pdflatex`, setting this option **ON** will result in pdf versions of the documentation being built. This feature is experimental.
Added check for pdflatex when building PDF documentation. Documented new configuration option for CMake in RELEASE_NOTES.md

[NCF-272] It turns out that HDF4 supports chunking (and compression). However the existing HDF4 code does not support it. So add HDF4 support for chunking. Also add a test case.
2014-05-31 12:12:05 +08:00
* Fix HDF4 files to support chunking.
[NCF-272](https://bugtracking.unidata.ucar.edu/browse/NCF-272)
When creating the libnetcdf.settings file, CMake-based builds now include compiler and linker debug or release flags.
2014-06-04 00:47:01 +08:00
* NetCDF creates a `libnetcdf.settings` file after configuration now, similar to those generated by `HDF4` and `HDF5`. It is installed into the same directory as the libraries. [NCF-303](https://bugtracking.unidata.ucar.edu/browse/NCF-303).
Merge branch 'ward-working'
2014-06-04 00:48:58 +08:00
Renamed man4 directory to docs.
2014-05-22 04:40:39 +08:00

Cleaning up Doxygen warnings, reorganization of top-level documentation.
2014-07-15 06:56:42 +08:00
* Removed redundant variable `BUILD_DOCS` from the CMake configuration file. See the issue at github: [#59](https://github.com/Unidata/netcdf-c/issues/59).
Removed redundant BUILD_DOCS CMake variable.
2014-05-22 04:13:23 +08:00
Fixed an issue with missing Doxygen files.
2014-05-13 00:43:01 +08:00
* Added missing documentation templates to `man4/Makefile.am`, to correct an issue when trying to build the local `Doxygen`-generated documentation. This issue was reported by Nico Schlömer and may be viewed on github. [Releases miss Doxygen files #56](https://github.com/Unidata/netcdf-c/issues/56)
Account for the HDF5 library not having the MPI-POSIX VFD configured in.
2014-05-07 21:45:15 +08:00
* When the NC_MPIPOSIX flag is given for parallel I/O access and the HDF5 library does not have the MPI-POSIX VFD configured in, the NC_MPIPOSIX flag is transparently aliased to the NC_MPIIO flag within the netCDF-4 library.
Added release date for 4.3.2 to release notes.
2014-04-24 04:02:41 +08:00

2014-04-16 05:31:57 +08:00
Updated release notes with information regarding new CMake-only configuration options. These are not part of the autotools build because, as they relate to CTest, it would not make any sense.
2014-04-17 06:31:29 +08:00
* The oc .dodsrc reader was improperly handling the user name and password entries. [NCF-299](https://bugtracking.unidata.ucar.edu/browse/NCF-299)
* CTestConfig.cmake has been made into a template so that users may easily specify the location of an alternative CDash-based Dashboard using the following two options:
* `NC_TEST_DROP_SITE` - Specify an alternative Dashboard by URL or IP address.
* `NC_CTEST_DROP_LOC_PREFIX` - Specify a prefix on the remote webserver relative to the root directory. This lets CTest accommodate dashboards that do not live at the top level of the web server.
Cleaning up Doxygen warnings, reorganization of top-level documentation.
2014-07-15 06:56:42 +08:00
Added entry on returning NC_ENOTNC error instead of assertion violations for truncated file.
2014-04-22 00:53:33 +08:00
* Return an error code on open instead of an assertion violation for truncated file.
[NCF-299] When a .dodsrc file is present, and specifies user name and password, it is being ignored after the first time. Fix required a major rewrite of ocrc.c because it was mishandling a number of .dodsrc entries.
2014-04-17 04:08:12 +08:00

2014-02-19 05:21:22 +08:00
* Add an extended format inquiry method to the netCDF API: nc\_inq\_format\_extended. NC\_HAVE\_INQ\_FORMAT\_EXTENDED is defined in netcdf.h [NCF-273]
[NCF-273]/HZY-708311 Add a new function called nc_inq_format_extended that returns more detailed format information (vis-a-vis nc_inq_format) about an open dataset. Note that the netcdf API will present the file as if it had the format specified by nc_inq_format. The true file format, however, may not even be a netcdf file; it might be DAP, HDF4, or PNETCDF, for example. This function returns that true file type. It also returns the effective mode for the file. signature: nc_inq_format_extended(int ncid, int* formatp, int* modep) where * ncid is the NetCDF ID from a previous call to nc_open() or nc_create(). * formatp is a pointer to a location for returned true format. * modep is a pointer to a location for returned mode flags. Refer to the actual list in the file netcdf.h to see the currently defined set. Also added test cases (tst_formatx*).

* Fixed fill value handling for string types in nc4\_get\_vara().
* Corrected behavior of nc\_inq\_unlimdim and nv\_inq\_unlimdims to report dimids
in same order as nc\_inq\_dimids.
Switch test for nc_inq_unlimdim and nc_inq_unlimdims to use the same ordering as the rest of the dimension queries. Correct error in library where types used in sub-group variables but that were added to the file after the sub-group was created weren't available for sub-group variables to use. Start cleaning up test suite and un-commenting tests that were commented out (got up to nc_test4/tst_fills2.c, alphabetically) before running into an error in HDF5.

Added test contributed by Jeff Whitaker.
2013-12-11 06:50:20 +08:00
* Fixed bug in ncgen; it was not properly filling empty string constants ("") to be the proper length. [NCF-279]
1. [NCF-276]/XXI-796914 Columbia server does not serve up proper opendap DDS replies. The Dataset {...} name changes depending on if the request has certain kinds of constraints. Code for a hack was not being used, so restore it. The fix is to effectively ignore differences in Dataset node names if the code is coming from columbia.edu. 2. [NCF-278] The ncgen code is improperly typing int64 integer constants as uint64. 3. [NCF-279] Empty string constants were not being properly filled when their target array is length 1 or more.

[NCF-271] Fix bug introduced by [NCF-267]. The bug was that octal constants that had the highest bit set (e.g. '\200') were not recognized as proper octal constants. Fix was to keep as integer until it was needed as an 8-bit byte.

[NCF-265] Ncgen is unable to resolve ambiguous references to an enum constant when two different enums have same econstant name. Solved by allowing more specific forms for econstant references. 1. /.../enumname.enumconstname 2. enumname.enumconstname 3. enumconstname Case 1 is resolved by using the econstant in the specific enum definition. If none is found, an error is reported. Case 2 is resolved by 1. finding an enclosing group with an enum definition with the specified name and containing the specified econstant. If there are more than one, then an error is reported 2. finding all enum definitions in the dataset that have the specified enum name and contain the specified econstant. If more than one is found, then an error is reported. If the above two methods fail, then report an error. Case 3 is similar to case 2, but all enums, irrespective of name are used if they contains the specified enum constant. The ref_tst_econst.cdl test in ncdump is causing ncdump to fail. So there may be yet some problem.

* Fix issue of netCDF-4 parallel independent access with unlimited dimension hanging. Extending the size of an unlimited dimension in HDF5 must be a collective operation, so now an error is returned if trying to extend in independent access mode. [NCF-250]
[NCF-250]: https://bugtracking.unidata.ucar.edu/browse/NCF-250
* Fixed bug with netCDF-4's inability to read HDF5 scalar numeric attributes. Also allow, in addition to zero length strings, a new NULL pointer as a string value. to improve interoperability with HDF5. This required a new CDL constant, 'NIL', that can be output from ncdump for such a string value in an HDF5 or netCDF-4 file. The ncgen utility was also modified to properly handle such NIL values for strings. [NCF-56]
[NCF-56]: https://bugtracking.unidata.ucar.edu/browse/NCF-56
* Parallel-build portability fixes, particularly for OpenMPI and gcc/gfortran-4.8.x on OSX.
* Fix contributed by Nath Gopalaswamy to large file problem reading netCDF classic or 64-bit offset files that have a UINT32_MAX flag for large last record size of a variable that has values larger than 1 byte. This problem had previously been fixed for *writing* such data, but was only tested with an ncbyte variable.
* Fixed various minor documentation problems.

2013-05-08 04:54:54 +08:00
* Patched libdap2/ncdap3.c to fix DAP performance bug remotely accessing large files (> 2GiB).
* Patched ncdump/dumplib.c to properly escape special characters in CDL output from ncdump for netCDF-4 string data.
### 4.2.1 Released 2012-07-18
* Added a specific NC\_MMAP mode flag to modify behavior of NC\_DISKLESS.
* Changed the file protections for NC\_DISKLESS created files to 0666
[NCF-182]
* Fixed ncdump to report error when an unsupported option is specified.
[NCF-180]
* Fixed documentation of CDL char constants in Users Guide and ncgen man
page.
* Fixed memory leak detected by valgrind in one of the HDF5 tests.
* Fixed problem with \#elif directives in posixio.c revealed by PGI
compilers.
### 4.2.1-rc1 Released 2012-06-18
* Ported static and shared libraries (DLL's) for both 32- and 64-bit
Windows, including support for DAP remote access, with netCDF-3 and
netCDF-4/HDF5 support enabled. The environment for this build is
MSYS/MinGW/MinGW64, but the resulting DLLs may be used with Visual
Studio. [NCF-112] [NCF-54] [NCF-57] [NCF-65]
* Implemented diskless files for all netCDF formats. For nc\_create(),
diskless operation performs all operations in memory and then optionally
persists the results to a file on close. For nc\_open(), but only for
netcdf classic files, diskless operation caches the file in-memory,
performs all operations on the memory resident version and then writes
all changes back to the original file on close.
[NCF-110][NCF-109][NCF-5]
* Added MMAP support. If diskless file support is enabled, then it is
possible to enable implementation of diskless files using the operating
system's MMAP facility (if available). The enabling flag is
"--enable-mmap". This is most useful when using nc\_open() and when only
parts of files, a single variable say, need to be read.
* Added configure flag for --disable-diskless.
* Added nccopy command-line options to exploit diskless files, resulting
in large speedups for some operations, for example converting unlimited
dimension to fixed size or rechunking files for faster access. Upgraded
doxygen and man-page documentation for ncdump and nccopy utilities,
including new -w option for diskless nccopy, with an example.
* Modified Makefile to allow for concurrent builds and to support builds
outside the source tree, e.g. 'mkdir build; cd build;
SOURCE-DIR/configure' where SOURCE-DIR is the top-level source
directory.
* Fixed some netCDF-4 bugs with handling strings in non-netCDF-4 HDF5
files. [NCF-150]
* Fixed bug using nccopy to compress with shuffling that doesn't compress
output variables unless they were already compressed in the input file.
[NCF-162]
* Fixed bug in 64-bit offset files with large records, when last record
variable requires more than 2\*\*32 bytes per record. [NCF-164]
* Fix bug in which passing a NULL path to nc\_open causes failure.
[NCF-173]
* Fixed ncgen bugs in parsing and handling opaque data.
* Fixed ncdump bug, not escaping characters special to CDL in enumeration
labels. [NCF-169]
* Fixed bug reading netCDF int into a C longlong or writing from longlong
to external int on 32-bit platforms with classic format files. The upper
32 bits of the longlong were not cleared on read or used on write.
[NCF-171]
* Resolved some erroneous returns of BADTYPE errors and RANGE errors due
to conflating C memory types with external netCDF types when accessing
classic or 64-bit offset files. [NCF-172]
* Fixed bug with ncdump -t interpreting unit attribute without base time
as a time unit. [NCF-175]
* Changed port for testing remote access test server to increase
reliability of tests.
* Modified ncio mechanism to support multiple ncio packages, so that it is
possible to have e.g. posixio and memio operating at the same time.
* Generation of documentation is disabled by default. Use --enable-doxygen
to generate. [NCF-168]
* Added description of configure flags to installation guide.
* Clarified documentation of arguments to nc**open() and nc**create() and
their default values.
* Fixed doxygen installation guide source file to preserve line breaks in
code and scripts. [NCF-174]
* Cleaned up a bunch of lint issues (unused variables, etc.) and some
similar problems reported by clang static analysis.
* Updated and fixed pkg-config source file netcdf.pc.in to work with
separated netCDF language-specific packages. Also fixed nc-config to
call nf-config, ncxx-config, and ncxx4-config for for backward
compatibility with use of nc-config in current Makefiles. [NCF-165]

2013-05-08 04:54:54 +08:00
* Completely rebuilt the DAP constraint handling. This primarily affects
users who specify a DAP constraint as part of their URL. [NCF-120]
* Fixed cause of slow nccopy performance on file systems with many records
and large disk block size or many record variables, by accessing data a
record at a time instead of a variable at a time. [NCF-142]
* Performance improvement to DAP code to support fetching partial
variables into the cache; especially important when using nc\_get\_var()
API. A partial variable is one that has ranges attached to the
projection variables (e.g. x[1:10][20:21]) [NCF-157]
* Separate the Fortran and C++ libraries and release the C library and
ncdump/ncgen/nccopy without Fortran or C++. [NCF-24]
* Documentation mostly migrated to Doxygen, from Texinfo. [NCF-26]
* Properly convert vara start/count parameters to DAP [NCF-105][NCF-106]
* Fixed major wasted space from previous default variable chunk sizes
algorithm. [NCF-81]
* Fixed bug in nccopy, in which compression and chunking options were
ignored for netCDF-4 input files. [NCF-79]
* Fixed bug in ncgen in which large variables (more than 2**18 elements)
duplicates the first 2**18 values into subsequent chunks of data
[NCF-154].
* Applied Greg Sjaardema's nccopy bug fix, not compressing output
variables f they were not already using compression on the input file
when shuffle specified. [NCF-162]
* Fixed problem when a URL is provided that contains only a host name.
[NCF-103]
* Fixed behavior of ncgen flags so that -o =\> -lb and, in the absence of
any other markers, make the default be -k1 [NCF-158]
* Created a text INSTALL file for netCDF-4.2 release. [NCF-161]
* Fixed bug in ncgen for vlen arrays as fields of compound types where
datalists for those types was improperly interpreted [NCF-145] (but see
NCF-155).
* Improve use of chunk cache in nccopy utility, making it practical for
rechunking large files. [NCF-85]
* Fixed nccopy bug copying a netCDF-4 file with a chunksize for an
unlimited dimension that is larger than the associated dimension size.
[NCF-139]
* Fixed nccopy bug when rechunking a netCDF-4 file with a chunkspec option
that doesn't explicitly specify all dimensions. [NCF-140]
* Fixed bug in netCDF-4 files with non-coordinate variable with the same
name as a dimension. [NCF-141]
* Incorporated Wei Huang's fix for bug where netCDF-4 sometimes skips over
too many values before adding fill values to an in-memory buffer.
[NCF-143]
* Fixed ncgen bug with netCDF-4 variable-length constants (H/T to Lynton
Appel). [NCF-145]
* Incorporated Peter Cao's performance fixes using HDF5 link iterator for
any group with many variables or types. [NCF-148]
* Incorporated Constantine Khroulev's bug fix for invalid usage of
MPI\_Comm\_f2c in nc\_create\_par. [NCF-135]
* Fixed turning off fill values in HDF5 layers when NOFILL mode is set in
netCDF-4 API (thanks to Karen Schuchardt). [NCF-151]
* Fixed bug with scalar coordinate variables in netCDF-4 files, causing
failure with --enable-extra-tests [NCF-149]
* Cleaned up the definition and use of nulldup. [NCF-92][NCF-93][NCF-94]
* Fixed various '\#include' bugs. [NCF-91][NCF-96][NCF-127]
* v2 API functions modified to properly call the external API instead of
directly calling the netcdf-3 functions. [NCF-100]
* Fixed problem with 64-bit offset format where writing more than 2\*\*31
records resulted in erroneous NC\_EINVALCOORDS error. [NCF-101]
* Restored original functionality of ncgen so that a call with no flags,
only does the syntax check. [NCF-104]
* Corrected misc. test bugs [NCF-107]
* Modified ncdump to properly output various new types (ubyte, ushort,
uint, int64, and uint64). [NCF-111]
* Fixed incorrect link flag for szip in configure.ac [NCF-116]
* ncdump -t now properly parses ISO "T" separator in date-time strings.
[NCF-16]
* ncdump -t "human time" functionality now available for attributes and
bounds variables [NCF-70]
* In ncdump, add -g option to support selection of groups for which data
is displayed. [NCF-11]
* Now supports bluefire platform [NCF-52]
* ncdump now properly displays values of attributes of type NC\_USHORT as
signed shorts [NCF-82]
* Rename some code files so that there are no duplicate filenames.
[NCF-99]
* Demonstration of netCDF-4 Performance Improvement with KNMI Data
[NCF-113]
* Dimension size in classic model netCDF-4 files now allows larger sizes
than allowed for 64-bit offset classic files. [NCF-117]
* ncdump now reports correct error message when "-x" option specifying
NcML output is used on netCDF-4 enhanced model input. [NCF-129]
* Fixed bug causing infinite loop in ncdump -c of netCDF-4 file with
subgroup with variables using inherited dimensions. [NCF-136]

* Replace use of --with-hdf5= and other such configure options that
violate conventions and causes build problems. Set environment variables
CPPFLAGS, LDFLAGS, and LD\_LIBRARY\_PATH instead, before running
configure script. [NCF-20]
* Detect from configure script when szlib is needed [NCF-21]
* Fix bug that can silently zero out portions of a file when writing data
in nofill mode beyond the end of a file, crossing disk-block boundaries
with region to be written while in-memory buffer is in a specific state.
This bug was observed disabling fill mode using Lustre (or other large
blksize file system) and writing data slices in reverse order on disk.
[NCF-22]
* Fix bug that prevents netCDF-4/HDF5 files created with netCDF-4.1.2 from
being read by earlier versions of netCDF or HDF5 versions before 1.8.7.
[NCF-23]
* Fix bug in configure that did not make the search for the xdr library
depend on --enable-dap. [NCF-41]
* Fix ncgen bug that did not use the value of a \_Format attribute in the
input CDL file to determine the kind of output file created, when not
specified by the -k command-line flag. [NCF-42]
* Fix ncgen bug, not properly handling unsigned longlong parsing. [NCF-43]
* Fix DAP client code to suppress variables with names such as "x.y",
which DAP protocol interprets as variable "y" inside container "x". Such
variables will be invisible when accessed through DAP client. [NCF-47]
* Define uint type for unsigned integer, if not otherwise available.
Symptom was compile error involving uint in putget.c. [NCF-49]
* Fix username+password handling in the DAP client code. [NCF-50]
* Add test for handling parallel I/O problem from f77 when user forgets to
turn on one of the two MPI flags. [NCF-60]
* Resolved "make check" problems when ifort compiler. Some "make install"
problems remain when using MPI and shared libraries. [NCF-61]
* Fix problem with f90\_def\_var not always handle deflate setting when
compiler was ifort. [NCF-67]
* Check that either MPIIO or MPIPOSIX flag is set when parallel create or
open is called. Also fix examples that didn't set at least one of these
flags. [NCF-68]
* Improve documentation on handling client-side certificates [NCF-48]
* Document that array arguments, except in varm functions, must point to
contiguous blocks of memory. [NCF-69]
* Get netCDF-4 tests working for DLLs generated with mingw. [NCF-6]
* Make changes necessary for upgrading to HDF5 1.8.7 [NCF-66]

* Stop looking for xdr if --disable-dap is used.
* Don't try to run (some) fortran configure tests on machines with no
fortran.
* Allow nccopy to rechunk with chunksizes larger than current dimension
lengths.
* Initial implementation of CDMREMOTE is complete; needs comprehensive
testing.
### 4.1.3-beta1 2011-04-29
* Fixed szlib not linking bug.
* Fixed dreaded "nofill bug", lurking in netCDF classic since at least
1999. Writing more than a disk block's worth of data that crossed disk
block boundaries more than a disk block beyond the end of file in nofill
mode could zero out recently written earlier data that hadn't yet been
flushed to disk.
* Changed setting for H5Pset\_libver\_bounds to ensure that all netCDF-4
files can be read by HDF5 1.8.x.
* Merged libncdap3 and libncdap4 into new libdap2 library. The suffix dap2
now refers to the dap protocol. This is in prep for adding dap4 protocol
support.
* Took out --with-hdf5 and related options due to high cost of maintaining
this non-standard way of finding libraries.

2013-05-08 04:54:54 +08:00
* Changes in build system to support building dlls on cygwin/mingw32.
* Changes to fix portability problems and get things running on all test
platforms.
* Some minor documentation fixes.
* Fixed opendap performance bug for nc\_get\_vars; required adding
nc\_get\_var{s,m} to the dispatch table.
* Now check for libz in configure.ac.
* Fixed some bugs and some performance problems with default chunksizes.
### 4.1.2-beta2 2011-01-11
* Add "-c" option to nccopy to specify chunk sizes used in output in terms
of list of dimension names.
* Rewrite netCDF-4 attribute put code for a large speedup when writing
lots of attributes.
* Fix nc-config --libs when static dependent libraries are not installed
in the same directory as netCDF libraries (thanks to Jeff Whitaker).
* Build shared libraries by default, requiring separate Fortran library.
Static libraries now built only with --disable-shared.
* Refactor of HDF5 file metadata scan for large speedup in opening files,
especially large files.
* Complete rewrite of the handling of character datalist constants. The
heuristics are documented in ncgen.1.
* Eliminate use of NC\_MAX\_DIMS and NC\_MAX\_VARS in ncdump and nccopy,
allocating memory as needed and reducing their memory footprint.
* Add documentation for new nc\_inq\_path() function.
* Use hashing to speedup lookups by name for files with lots of dimensions
and variables (thanks to Greg Sjaardema).
* Add options to nccopy to support uniform compression of variables in
output, shuffling, and fixing unlimited dimensions. Documented in
nccopy.1 man page and User's Guide.
### 4.1.2-beta1 2010-07-09
* Fix "ncdump -c" bug identifying coordinate variables in groups.
* Fix bug in libsrc/posixio.c when providing sizehint larger than default,
which then doesn't get used (thanks to Harald Anlauf).
* Fix netCDF-4 bug caused when doing enddef/redef and then defining
coordinate variable out of order.
* Fixed bug in man4 directory automake file which caused documentation to
be rebuilt after make clean.
* Turned off HDF5 caching when parallel I/O is in use because of its
memory use.
* Refactoring of netCDF code with dispatch layer to decide whether to call
netCDF classic, netCDF-4, or opendap version of a function.
* Refactoring of netCDF-4 memory internals to reduce memory use and end
dependence on NC\_MAX\_DIMS and NC\_MAX\_NAME.
* Modified constraint parser to be more compatible with a java version of
the parser.
* Modified ncgen to utilize iterators internally; should be no user
visible effect.
* Fixed two large-file bugs with using classic format or 64-bit offset
format and accessing multidimensional variables with more than 2\*\*32
values.

* Much better memory leak checking with valgrind.
* Added per-variable chunk cache control for better performance. Use
nc\_set\_var\_chunk\_cache / nf\_set\_var\_chunk\_cache /
nf90\_set\_var\_chunk\_cache to set the per-variable cache.
* Automatically set per-variable chunk cache when opening a file, or
creating a variable, so that the cache is big enough for more than one
chunk. (Can be overridden by user). Settings may be changed with
configure options --max-default-chunk-size and
--default-chunks-in-cache.
* Better default chunks size. Now chunks are sized to fit inside the
DEFAULT\_CHUNK\_SIZE (settable at configure time with
--with-default-chunk-size= option.)
* Added nccopy utility for converting among netCDF format variants or to
copy data from DAP servers to netCDF files.
* The oc library has been modified to allow the occurrence of alias
definitions in the DAS, but they will be ignored.
* The old ncgen has been moved to ncgen3 and ncgen is now the new ncgen4.
* Modified --enable-remote-tests to be on by default.
* Fixed the nc\_get\_varm code as applied to DAP data sources.
* Added tests for nc-config.
* Many documentation fixes.
Use PnetCDF instead of parallel-netcdf to avoid confusion with parallel netcdf4. Also, update PnetCDF web page.

perform parallel I/O on classic and 32-bit offset files. Use the
NC\_PNETCDF mode flag to get parallel I/O for non-netcdf-4 files.
* Added libcf library to netCDF distribution. Turn it on with configure
option --with-libcf.
* Added capability to read HDF4 files created with the SD (Scientific
Data) API.
* The DAP support was revised to closely mimic the original libnc-dap
support.
* Significantly revised the data handling mechanism in ncgen4 to more
closely mimic the output from the original ncgen.
* Added prototype NcML output capability to ncgen4. It is specified by the
-lcml flag.
* Added capability to read HDF5 files without dimension scales. This will
allow most existing HDF5 datasets to be read by netCDF-4.
* Fixed bug with endianness of default fill values for integer types when
variables are created with a non-native endiannesss and use the default
fill value.
* Significant refactoring of HDF5 type handling to improve performance and
handle complicated nesting of types in cross-platform cases.
* Added UDUNITS2 to the distribution. Use --with-udunits to build udunits
along with netcdf.
* Made changes suggested by HDF5 team to relax creation-order requirement
(for read-only cases) which allows HDF5 1.6.x files to be retrofitted
with dimension scales, and be readable to netCDF-4.
* Handle duplicate type names within different groups in ncdump. Fix group
path handling in absolute and relative variable names for "-v" option.
* Added nc-config shell script to help users build netCDF programs without
having to figure out all the compiler options they will need.
* Fixed ncdump -s bug with displaying special attributes for classic and
64-bit offset files.
* For writers, nc\_sync() now calls fsync() to flush data to disk sooner.
* The nc\_inq\_type() function now works for primitive types.

2013-05-08 04:54:54 +08:00
* Added optional arguments to F90 API to nf90\_open/create,
nf90\_create\_var, and nf90\_inquire\_variable so that all netCDF-4
settings may be accomplished with optional arguments, instead of
separate function calls.
* Added control of HDF5 chunk cache to allow for user performance tuning.
* Added parallel example program in F90.
* Changed default chunking to better handle very large variables.
* Made contiguous the default for fixed size data sets with no filters.
* Fixed bug in nc\_inq\_ncid; now it returns NC\_ENOGRP if the named group
is not found.
* Fixed man pages for C and F77 so that netCDF-4 builds will result in man
pages that document new netCDF-4 functions.
* Added OPeNDAP support based on a new C-only implementation. This is
enabled using --enable-dap option and requires libcurl. The configure
script will attempt to locate libcurl, but if it fails, then its
location must be specified by the --with-curl option.
### 4.0.1-beta2 2008-12-26
* Changed chunksizes to size\_t from int.
* Fixed fill value problem from F77 API.
* Fixed problems in netcdf-4 files with multi-dimensional coordinate
variables.
* Fixed ncgen to properly handle CDL input that uses Windows line endings
("\r\n"), instead of getting a syntax error.
Spelling fixes

netCDF-4 files as special virtual attributes, such as \_Chunking,
\_DeflateLevel, \_Format, and \_Endianness.
* Added "-t" option to ncdump to display times in human readable form as
strings. Added code to interpret "calendar" attribute according to CF
conventions, if present, in displaying human-readable times.
* Added experimental version of ncgen4 capable of generating netcdf-4 data
files and C code for creating them. In addition, it supports the special
attributes \_Format, etc.
* 4.0.1-beta1 2008-10-16
* Fixed Fortran 90 int64 problems.
* Rewrote HDF5 read/write code in accordance with performance advice from
Kent.
* Fixed memory leaks in gets/puts of HDF5 data.
* Fixed some broken tests for parallel I/O (i.e. MPI) builds.
* Fixed some cross-compile problems.
* Rewrote code which placed bogus errors on the HDF5 error stack, trying

* Removed man subdirectory. Now man4 subdirectory is used for all builds.
* Changed build so that users with access to parallel make can use it.
* Added experimental support for accessing data through OPeNDAP servers
using the DAP protocol (use --enable-opendap to build it).
* Fixed ncdump bugs with array field members of compound type variables.
Fixed ncdump bug of assuming default fill value for data of type
unsigned byte.

* In ncdump and ncgen, added CDL support for UTF-8 encoding of characters
in names and for escaped special chars in names. Made sure UTF-8 names
are normalized using NFC rules before storing or comparing.
* Handle IEEE NaNs and infinities in a platform-independent way in ncdump
output.
* Added support for ARM representation of doubles, (thanks to Warren
Turkal).
* Fixed bug in C++ API creating 64-bit offset files. (See

* Changed the configure.ac to build either 3.6.x or 4.x build from the
same configure.ac.
* Build now checks gfortran version and handles it cleanly, also Portland
Group in Intel fortran, with various configurations.
* A Fortran netcdf.inc file is now created at build time, based on the
setting of --disable-v2.
* Documentation has been fixed in several places.
* Upgraded to automake 1.10, autoconf 2.62, and libtool 2.2.2.
* Includes missing Windows Visual Studio build files.
* Fixed missing include of config.h in a C++ test program.
* Fixed maintainer-clean in man directory.

## 3.6.2 2007-03-05
Added markdown version of RELEASE_NOTES for evaluation. Modified Doxyfile templates to generate html from the markdown file (assumes doxygen version 1.8+) Added link to release notes to mainpage.doc
2013-05-08 04:54:54 +08:00
* Released.
### 3.6.2 beta6 2007-01-20
* Fine tuning of build system to properly handle cygwin, Mingw, and
strange configuration issues.
* Automake 1.10 has a problem with running our tests on MinGW, so I'm
switching back to automake 1.9.6 for this release.
### 3.6.2 beta5 2006-12-30
* Now netCDF configuration uses autoconf 2.61, and automake 1.10. (Thanks
to Ralf Wildenhues for the patches, and all the autotools help in
general!)
* Final major revision of netCDF tutorial before the 3.6.2 release.
* Now netCDF builds under MinGW, producing a windows DLL with the C and
F77 APIs. Use the --enable-shared --enable-dll --disable-cxx
--disable-f90 flags to configure. (C++ and F90 have never been built as
windows DLLs, but might be in a future release if there is user
interest). This has all been documented in the netCDF Porting and
Installation Guide.
* Now extreme numbers (i.e. those close to the limits of their type) can
be turned off in nc\_test/nf\_test, with --disable-extreme-numbers. It
is turned off automatically for Solaris i386 systems.
* Added --enable-c-only option to configure. This causes only the core
netCDF-3 C library to be built. It's the same as --disable-f77
--disable-cxx --disable-v2 --disable-utilities.
* Added --disable-utilities to turn off building and testing of
ncgen/ncdump.
* Fix a long-standing bug in nf90\_get\_att\_text() pointed out by Ryo
Furue, to make sure resulting string is blank-padded on return. This is
fixed in the Fortran-90 interface, but is impractical to fix in the
Fortran-77 interface implemented via cfortran.h.
* Now large file tests are run if --enable-large-file-tests is used in the
configure.
* For Cray users, the ffio module is used if the --enable-ffio option is
passed to configure.
* Unrolled loops in byte-swapping code used on little-endian platforms to
reduce loop overhead. This optimization resulted in a 22% speedup for
some applications accessing floats or ints (e.g. NCO utilities ncap and
ncbo) and a smaller speedup for shorts or doubles.
* Added "-k" option to ncdump and ncgen, for identifying and specifying
the kind of netCDF file, one of "classic", "64-bit-offset", "hdf5", or
"hdf5-nc3". Removed output of kind of netCDF file in CDL comment
produced by ncdump.
* Fixed bug of ncdump seg-faulting if invoked incorrectly with option like
"-c" or "-h" but no file name.
### 3.6.2 beta4 2006-08-15
* Changed F77/F90 man pages from netcdf.3f and netcdf.3f90 to
netcdf\_f77.3 and netcdf\_f90.3. Also fixed broken install of man pages.
* Changed configure script so that "-g -O2" is no longer set as CFLAGS,
CXXFLAGS, and FFLAGS by default if a GNU compiler is being used. Now
nothing is set.
* Changed configure script so that fortran flag is set in config.h.
* Updated Installation and Porting Guide, C++ Interface Guide, F77 and F90
Interface Guides.
* Build with static libraries by default.
* Added configure option --enable-separate-fortran, which causes the
fortran library to be built separately. This is turned on automatically
for shared libraries.
* Improved clarity of error messages.
* Changed configuration to get cygwin DLL and mingw DLL builds working,
for the C library only (i.e. no F77, F90, or C++ APIs).
* Changed type of ncbyte in C++ interface from unsigned char to signed
char, for consistency with C interface. The C++ documentation warned
this change would eventually occur.
* Changed the C++ interface to use only the netCDF-3 C interface instead
of the older netCDF-2 C interface. This has the added benefit that
on-the-fly numeric conversions are now supported using get methods, for
example you can get data of any type as double. When using --disable-v2
flag to configure, the C++ interface can now be built and installed.
### 3.6.2 beta3 2006-05-24
* Changed to use default prefix of /usr/local instead of package-based
prefix of previous releases of netCDF. Use the --prefix argument to the
configure script to override the default.
* Made separate fortran library file, instead of appending fortran library
functions to the C library file, if --enable-separate-fortran is used
during configure (it's turned on automatically if --enable-shared is
used). If uses, the fortran API users must link to *both* the C library
and the new fortran library, like this: -lnetcdff -lnetcdf
* Added netCDF examples in C, C++, F77, F90, and CDL. See the examples
subdirectory.
* Added the NetCDF Tutorial.
* Minor fixes to some of the netCDF documentation.
* Made it possible to build without V2 API using --disable-v2 from
configure.
* Switched to new build system, with automake and libtool. Now shared
libraries are built (as well as static ones) on platforms which support
it. For more information about shared libraries, see

* Fixed ncdump crash that happened when no arguments were used.
* Fixed for building with gfortran 4.1.0.
* Important fix for machines whose SIZEOF\_SIZE\_T != SIZEOF\_LONG, such
as NEC-SX, thanks to Stephen Leak.
* Fixed C++ on AIX platform.
* Fixed 64-bit builds on AIX platform.
* Removed bad assertion that could be triggered in rare cases when reading
a small file.
* Added comments in v1hpg.c to clarify purpose of each internal function.
* Make sure filesize is determined in nc\_close() *after* buffers get
flushed.
* Fix long-standing problem resulting in files up to 3 bytes longer than
necessary if there is exactly one record variable of type byte, char, or
short and if the number of values per record for that variable is not
divisible by 4 (or 2 in the case of short). Now the filesize determined
from header info by NC\_calcsize should be correct in all cases.

## 3.6.1 2006-01-31
Added markdown version of RELEASE_NOTES for evaluation. Modified Doxyfile templates to generate html from the markdown file (assumes doxygen version 1.8+) Added link to release notes to mainpage.doc
2013-05-08 04:54:54 +08:00
* Updated installation manual for 3.6.1.
* Changed installation to try to provide correct compiler flags for
compiling in 64-bit mode on Sun, Irix, AIX, and HPUX. (HPUX doesn't work
for me, however). Now run configure with --enable-64bit to get a 64 bit
compile.
* Fixed long-standing bug that would cause small netCDF files to be padded
on the end with zero bytes to 4096 bytes when they were opened and
changed. Now small files should stay small after you change a value.
* Fixed bug in assertions in putget.c that would only be noticed if you
change the manifest constant NC\_MAX\_DIMS in netcdf.h to be different
from NC\_MAX\_VAR\_DIMS.
* Moved test ftest.F from fortran to nf\_test directory, and fixed bug in
ftest.F which caused it to return 0 even if tests failed (no tests were
failing, however). Also renamed some test output files to make things a
little clearer.
* If open for writing, pad with up to 3 extra zero bytes before close to
the correct canonical length, calculated from the header. Previously
files could be short due to not padding when writing in NOFILL mode.
* Doubled arbitrary limits on number of dimensions, variables, attributes,
and length of names.
* Change name of nc\_get\_format() to nc\_inq\_format(). Add analogous
interfaces for nf\_inq\_format(), nf90\_inquire(), and
NcFile::get\_format() to f77, f90, and C++ interfaces. Document new
function in texinfo files. Add minimal test to nc\_test, nf\_test.
### 3.6.1-beta3 2005-02-17
* Added function nc\_get\_format(int ncid, int\* formatp) that returns
either NC\_FORMAT\_CLASSIC or NC\_FORMAT\_64BIT for a CDF1 or CDF2 file,
respectively.
* Added test to nc\_test that detects whether format version was changed
after a file is reopened and define mode is entered.
* Correctly configure for Intel ifort Fortran compiler on Linux.
### 3.6.0-p1 2005-02-18
* Fixed bug that changes CDF2 files to CDF1 files if CDF2 file is reopened
for write access and either an attribute is changed or define mode is
entered.
### 3.6.1-beta2 2005-1-6
* Fixed absoft compile problem. Maybe.
### 3.6.1-beta1 2005-1-3
* Fixed Cygwin C++ problem.
* Fixed large file problem in MS Visual C++.NET environment.
* More information in installation and porting guide.

2013-05-08 04:54:54 +08:00
* Added texinfo source for the documentation.
* Added large file tests to Windows directory in distribution.
* Modified win32 visual studio project files so that m4 is no longer
required to build netcdf under visual studio.
* Modified rules.make to use install instead of cp, fixing install problem
for cygwin users.
* Modified configure/install stuff to support HP-UX.
* Modified configure/install stuff to support G95.
* In the f90 interface, applied Arnaud Desitter's fixes to correct
mismatches between scalar and array arguments, eliminating (legitimate)
complaints by the NAGWare f95 compiler. Also fixed bugs introduced in
3.6.0-beta5 in the mapped array interfaces.
### 3.6.0-beta6 2004-10-05
* Fixed AIX 64-bit/largefile install problems.
* Removed FAQ section from netcdf.texi User's Guide, in deference to
online version that can be kept up to date more easily.
### 3.6.0-beta5 2004-10-04
* Fixed assertion violation on 64-bit platforms when size of last fixed
size variable exceeds 2\^32 - 1.
* Removed another restriction on file size by making record size (derived
from other sizes, not part of the format) an off\_t instead of a
size\_t, when an off\_t is larger than a size\_t. This permits records
to be *much* larger in either classic format or 64-bit-offset format.
* Incorporated patch from Mathis Rosenhauer to improve performance of
Fortran 90 interface for calls to nf90\_put\_var\_TYPE(),
nf90\_get\_var\_TYPE(), nf90\_put\_vara\_TYPE(), and
nf90\_get\_vara\_TYPE() functions by not emulating them with the
corresponding nf90\_put\_varm\_TYPE() and nf90\_get\_varm\_TYPE() calls.
* Added tests for invalid offsets in classic format when defining multiple
large variables.
* Improved installation ease. Have configure script use Large File Support
as a default, if available.
* Add "extra\_test" as a target for testing Large File Support.
### 3.6.0-beta3 2004-08-24
* Upgraded to recent autoconf, changed configure to (hopefully) improve
installation. Also added macros to deal with large file systems.
* Added nf\_set\_default\_format to Fortran interface.
* Added testing to the set\_default\_format functions to nc\_test and
nf\_test.
* Added documentation to the man page for set\_default\_format functions.
* Added two new error return codes to C, f77, and f90 interfaces for
invalid dimension size and for bad variable size. Made test for max
dimension size depend on whether 64-bit offsets used. Fixed bug with
dimension sizes between 2\^31 and 2\^32 (for byte variables).
* Fixed ncdump to properly print dimensions larger than 2\^31.
* Fixed ncgen to properly handle dimensions between 2\^31 and 2\^32.

2013-05-08 04:54:54 +08:00
* Added -v2 (version 2 format with 64-bit offsets) option to
ncgen, to specify that generated files or generated C/Fortran code
should create 64-bit offset files. Also added -x option to ncgen to
specify use of no-fill mode for fast creation of large files.
* Added function to set default create mode to C interface
(nc\_set\_default\_create).
* Added win32 directory, with NET subdirectory to hold .NET port of
netCDF. To use, open netcdf.sln with Visual Studio, and do a clean and
then a build of either the debug or release builds. Tests will be run as
part of the build process. VC++ with managed extensions is required
(i.e. VC++.NET).
* Added windows installer files to build windows binary installs.

2013-05-08 04:54:54 +08:00
* By incorporating Greg Sjaardema's patch, added support for
64-bit offset files, which remove many of the restrictions relating to
very large files (i.e. larger than 2 GB.) This introduces a new data
format for the first time since the original netCDF format was
introduced. Files in this new 64-bit offset format can't be read by
earlier versions of netCDF. Users should continue to use the netCDF
classic format unless they need to create very large files.
* The test suite, nc\_test, will now be run twice, once for netCDF classic
format testing, and once for 64-bit offset format testing.
* The implementation of the Fortran-77 interface has been adapted to
version 4.3 of Burkhard Burow's "cfortran.h".

Added support for the ifc Fortran-90 compiler creating files "netcdf.d"
and "typesizes.d" (instead of ".mod" files).
* Fixed access to iargc and getarg functions from Fortran-90 for NAG f90
compiler, contributed by Harald Anlauf.

* Updated INSTALL.html for Mac OS X (Darwin).
* Made the installation of the netCDF Fortran-90 module file more robust
regarding the name of the file.
* Added support for eight-byte integers in Fortran90 interface.
* Increased advisory limits in C netcdf.h and Fortran netcdf.inc for
maximum number of dimensions, variables, and attributes.
* Changed C++ declarations "friend NcFile" to "friend class NcFile" in
cxx/netcdfcpp.h to conform to standard.
* Added Dan Schmitt's backward compatible extension to the C++ record
interface to work with arbitrary dimension slices.
* Added C++ documentation note that caller is responsible for deleting
pointer returned by Variable::values() method when no longer needed.
* Made C++ interface more standard; the result may not compile on some old
pre-standard C++ compilers.
* Fixed bug in ncgen when parsing values of a multidimensional char
variable that resulted in failure to pad a value with nulls on IRIX.
* Fixed ncdump bug adding extra quote to char variable data when using -fc
or -ff option.
* Fixed so compiling with -DNO\_NETCDF\_2 will work for building without
backward-compatibility netCDF-2 interfaces.
* Eliminated use of ftruncate(), because it fails on FAT32 file systems
under Linux.
* Initialized a pointer in putget.m4 (used to generate putget.c) that was
involved in uninitialized memory references when nc\_test is run under
Purify. Two users had reported seeing crashes resulting from this
problem in their applications.
* Reverted pointer initializations in putget.m4, after testing revealed
these caused a performance problem, resulting in many extra calls to
px\_pgin and px\_pgout when running nc\_test.
* Added checking of size of "dimids" vector in function
nf90\_inquire\_variable(...) and error-returning if it isn't
sufficiently capacious.
* Added variable index to ncvarget() and ncattinq() error messages and
attribute name to ncattinq() error message.
* Tweaked configure script to work with recent C++ compilers.
* Fixed a memory leak in C++ interface, making sure NcVar::cur\_rec[] gets
deleted in NcVar destructor.
* Reimplemented nc\_sync() fix of version 3.5.0 to eliminate performance
penalty when synchronization is unnecessary.
* Changed order of targets in Makefile to build Fortran interface last, as
a workaround for problem with make on AIX platforms.

* Added Fortran 90 interface.
* Changed C macro TIMELEN in file cxx/nctst.cpp to TIMESTRINGLEN to avoid
clash with macro defined on AIX systems in /usr/include/time.h.
* Fixed miswriting of netCDF header when exiting define mode. Because the
header was always written correctly later, this was only a problem if
there was another reader of the netCDF file.
* Fixed explicit synchronizing between netCDF writer and readers via the
nc\_sync(), nf\_sync(), and ncsync() functions.
* Fixed a number of bugs related to attempts to support shrinking the
header in netCDF files when attributes are rewritten or deleted. Also
fixed the problem that nc\_\_endef() did not work as intended in
reserving extra space in the file header, since the extra space would be
compacted again on calling nc\_close().
* Fixed the "redef bug" that occurred when nc\_enddef() or nf\_enddef() is
called after nc\_redef() or nf\_redef(), the file is growing such that
the new beginning of a record variable is in the next "chunk", and the
size of at least one record variable exceeds the chunk size (see
netcdf.3 man page for a description of this tuning parameter and how to
set it). This bug resulted in corruption of some values in other
variables than the one being added.
* The "\*\*" tuning functions for the Fortran interface, nf\*\*create,
nf\*\*open, and nf\*\*enddef, are now documented in the Fortran interface
man pages.
* Add an 'uninstall' target to all the Makefiles. Dave Glowacki
<dglo@SSEC.WISC.EDU> 199810011851.MAA27335
* Added support for multiprocessing on Cray T3E. Hooks added by Glenn, but
the majority of the work was done at NERSC. Also includes changes to
ffio option specification. Patch rollup provided by R. K. Owen
<rkowen@Nersc.GOV>. The following functions are added to the public
interface. nc**create\_mp() nc**open\_mp() nc\_set\_base\_pe()
nc\_inq\_base\_pe()
* Fixed makefile URL for Win32 systems in INSTALL file.
* Made test for UNICOS system in the configure script case independent.
* Ported to the following systems: AIX 4.3 (both /bin/xlc and
/usr/vac/bin/xlc compilers) IRIX 6.5 IRIX64 6.5
* Changed the extension of C++ files from ".cc" to ".cpp". Renamed the C++
interface header file "netcdfcpp.h" instead of "netcdf.hh", changing
"netcdf.hh" to include "netcdfcpp.h" for backward compatibility.
* Treat "FreeBSD" systems the same as "BSD/OS" system w.r.t. Fortran and
"whatis" database.
* Corrected manual pages: corrected spelling of "enddef" (was "endef") and
ensured that the words "index" and "format" will be correctly printed.
* Updated support for Fortran-calling-C interface by updating
"fortran/cfortran.h" from version 3.9 to version 4.1. This new version
supports the Portland Group Fortran compiler (C macro "pgiFortran") and
the Absoft Pro Fortran compiler (C macro "AbsoftProFortran").
* Corrected use of non-integral-constant-expression in specifying size of
temporary arrays in file "libsrc/ncx\_cray.c".
* Added Compaq Alpha Linux workstation example to INSTALL file.
* Ported cfortran.h to Cygnus GNU Win32 C compiler (gcc for Windows).
* Fixed bug in ncdump using same CDL header name when called with multiple
files.
* Added new NULL data type NC\_NAT (Not A Type) to facilitate checking
whether a variable object has had its type defined yet, for example when
working with packed values.
* Fixed use of compile-time macro NO\_NETCDF\_2 so it really doesn't
include old netCDF-2 interfaces, as intended.
* Ported to MacOS X Public Beta (Darwin 1.2/PowerPC).
* Fixed C++ friend declarations to conform to C++ standard.
* Changed INSTALL file to INSTALL.html instead.
Updated RELEASE_NOTES to include mention of configuration files. Updated RELEASE_NOTES so that full releases are header-two, release-candidates are header-three.

## 3.4 1998-03-09
Added markdown version of RELEASE_NOTES for evaluation. Modified Doxyfile templates to generate html from the markdown file (assumes doxygen version 1.8+) Added link to release notes to mainpage.doc
2013-05-08 04:54:54 +08:00
* Fixed ncx\_cray.c to work on all CRAY systems, not just CRAY1. Reworked
USE\_IEG, which was incorrect. Reworked short support. Now USE\_IEG and
otherwise both pass t\_ncx.
* To better support parallel systems, static and malloc'ed scratch areas
which were shared in the library were eliminated. These were made
private and on the stack where possible. To support this, the macros
ALLOC\_ONSTACK and FREE\_ONSTACK are defined in onstack.h.
* The buffered i/o system implementation in posixio.c was reimplemented to
limit the number and size of read() or write() system calls and use
greater reliance on memory to memory copy. This saves a great deal of
wall clock time on slow (NFS) filesystems, especially during
nc\_endef().
* Added performance tuning "underbar underbar" interfaces nc**open(),
nc**create(), and nc\_\_enddef().
* The 'sizehint' contract between the higher layers and the ncio layer is
consistently enforced.
* The C++ interface has been updated so that the deprecated "nclong"
typedef should no longer be required, and casts to nclong no longer
necessary. Just use int or long as appropriate. nclong is still
supported for backwards compatibility.
* The ncdump utility now displays byte values as signed, even on platforms
where the type corresponding to a C char is unsigned (SGI, for example).
Also the ncdump and ncgen utilities have been updated to display and
accept byte attributes as signed numeric values (with a "b" suffix)
instead of using character constants.
* In libsrc/error.c:nc\_strerror(int), explain that NC\_EBADTYPE applies
to "\_FillValue type mismatch".
* Some changes to configure scripts (aclocal.m4), macros.make.in and
ncgen/Makefile to support NEC SUPER-UX 7.2.
* The "usage" messages of ncgen and ncdump include the string returned
from nc\_inq\_libvers().
* Corrected some casts in the library so that all phases of the arithmetic
computing file offsets occurs with "off\_t" type. This allows certain
larger netcdf files to be created and read on systems with larger
(64bit) off\_t.
* In ncgen, multidimensional character variables are now padded to the
length of last dimension, instead of just concatenating them. This
restores an undocumented but convenient feature of ncgen under netCDF-2.
Also, a syntax error is now reliably reported if the netcdf name is
omitted in CDL input.
* Fortran and C code generated by ncgen for netCDF components whose names
contain "-" characters will now compile and run correctly instead of
causing syntax errors.
* The library allows "." characters in names as well as "\_" and "-"
characters. A zero length name "" is explicitly not allowed. The ncgen
utility will now permit "." characters in CDL names as well.
* Memory leaks in the C++ interface NcVar::as\_\*() member functions and
NcFile::add\_var() member function are fixed. The documentation was
fixed where it indicated incorrectly that the library managed value
blocks that the user is actually responsible for deleting.
* he values of the version 2 Fortran error codes have been modified to
make the version 2 Fortran interface more backward compatible at the
source level.
* Added support for systems whose Fortran INTEGER*1 and INTEGER*2 types
are equivalent to the C "long" type but whose C "int" and "long" types
differ. An example of such a system is the NEC SX-4 with the "-ew"
option to the f90 compiler (sheesh, what a system!).
* Fixed Version 2 Fortran compatibility bug: NCVGTG, NCVGGC, NCVPTG, and
NCVPGC didn't work according to the Version 2 documentation if the
innermost mapping value (i.e. IMAP[1]) was zero (indicating that the
netCDF structure of the variable should be used).
Updated RELEASE_NOTES to include mention of configuration files. Updated RELEASE_NOTES so that full releases are header-two, release-candidates are header-three.

## 3.3.1 1997-06-16
Added markdown version of RELEASE_NOTES for evaluation. Modified Doxyfile templates to generate html from the markdown file (assumes doxygen version 1.8+) Added link to release notes to mainpage.doc
2013-05-08 04:54:54 +08:00
* One can now inquire about the number of attributes that a variable has
using the global variable ID.
* The FORTRAN interface should now work on more systems. In particular:
* It should now work with FORTRAN compilers whose "integer*1" datatype is
either a C "signed char", "short", or "int" and whose "integer*2"
datatype is either a C "short" or "int".
* It should now work with FORTRAN compilers that are extremely picky about
source code formatting (e.g. the NAG f90 compiler).
* The dependency on the non-POSIX utility m4(1) for generating the C and
FORTRAN manual pages has been eliminated.
* EXTERNAL statements have been added to the FORTRAN include-file
"netcdf.inc" to eliminate excessive warnings about "unused" variables
(which were actually functions) by some compilers (e.g. SunOS 4.1.3's
f77(1) version 1.x).
* Building the netCDF-3 package no longer requires the existence of the
Standard C macro RAND\_MAX.
* Fixed an ncdump bug resulting in ncdump reporting Attempt to convert
between text & numbers when \_FillValue attribute of a character
variable set to the empty string "".
* Made ncgen tests more stringent and fixed various bugs this uncovered.
These included bugs in handling byte attributes on platforms on which
char is unsigned, initializing scalar character variables in generated C
code under "-c" option, interspersing DATA statements with declaration
statements in generated Fortran code under "-f" option, handling empty
string as a value correctly in generated C and Fortran, and handling
escape characters in strings. The Fortran output under the "-f" option
was also made less obscure and more portable, using automatic conversion
with netCDF-3 interfaces instead of "BYTE", "INTEGER*1", or "INTEGER*2"
declarations.
* Fixed a C++ interface problem that prevented compiling the C++ library
with Digital's cxx compiler.
* Made ncgen "make test" report failure and stop if test resulted in a
failure of generated C or Fortran code.
* The file that you are now reading was created to contain a high-level
description of the evolution of the netCDF-3 package.

## 3.3 1997-05-15
Added markdown version of RELEASE_NOTES for evaluation. Modified Doxyfile templates to generate html from the markdown file (assumes doxygen version 1.8+) Added link to release notes to mainpage.doc
2013-05-08 04:54:54 +08:00
* The production version of the netCDF-3 package was released.
* A comparison of the netCDF-2 and netCDF-3 releases can be found in the
file COMPATIBILITY.
Reorganized doxygen documents, renamed .doc files as .dox. Bumped revision to 4.3.1.2. There may not be a 4.3.1.2 release, but I didn't want to leave it as 4.3.1.1. Removed CMake-specific doxygen/documentation template, made changes required so that CMake and autotools-based builds can use the same template (Doxyfile.in).
2014-02-20 07:32:26 +08:00
More reorganizing of the documentation generated by doxygen. Added a link to the main Unidata netcdf page to the footer, because we are going to turn off the header and footer on the web server. This should allow the Doxygen-generated search field to be properly placed.
