Description:
Library versions 1.6.3 and earlier contain a bug which causes them to be unable
to perform certain operations on a group if that group's symbol table
information is not cached in the parent group's symbol table. Versions 1.8.0
to 1.8.5 did not cache this information. Modified library to cache this
information.
Tested: jam, amani, heiwa (h5committest)
through H5Eset_auto. I changed the union in the structure H5E_auto_t. Another change is to
make H5Eget_auto fail if H5Eset_auto is called to set the printing function. I'll write a
document for it.
Tested on heiwa, jam, and amani.
The property change in configure.in, config, and Makefile.am came from the merge of the 1.8
library change.
Add --exclude-path option
Description:
Specified path to an object will be excluded from comparing the two files or two groups. If group is specified all the member objects will be excluded.
Related to "1890: h5diff excluding object for file comparison via command line"
Tested:
jam, amani and heiwa
Fix for Bug1975 h5diff - support recursive comparison on group when specified as an object
Description:
Compare member objects and groups recursively when two files or groups are specified to be compared. Support parallel diff and handling symbolic links accordingly.
Tested:
jam, amani, heiwa
Fix for Bug1896 h5repack - changing layout to COMPACT does not work
Description:
Make h5repack be able to convert a layout to COMPACT for small size dataset as default. Also add verifying layout changes in our test script.
Tested:
jam, amani, heiwa
Description:
The fractal heap header structure keeps a pointer to the file associated with
it. However, it is possible for that file pointer to be closed while the
header is still in cache (through the shared file pointer). Previously, the
header's file pointer was not updated and subsequently pointed to an invalid
file structure. Modified fractal heap code to update the file pointer every
time the header is accessed.
Tested: jam, linew, amani (h5committest)
Add windows threads support to HDF5.
Description:
Added calls to the windows threads library to the H5TS layer, and wrapped
most calls to either pthreads or windows threads library with portable
H5TS-style defines. Modified tests to use portable function definitions
as well.
This can be configured via CMake with the HDF5_ENABLE_THREADSAFE
option, and should work on windows vista and later operating systems.
Tested:
h5committest, plus threadsafe with pthreads on jam and amani,
and tested on a Windows Vista VM with threadsafe using windows threads.
H5T_ORDER_MIXED specifically for compound types and its derived types. They report mixed
orders if they have members of different orders.
There is no change to configure.in, config, and Makefile.am in the top directory. They have
some property changes when I merged the code from 1.8.
Tested on jam. I tested the same change for 1.8 with h5committest.
1. For enum type, members shouldn't be defined yet.
2. H5T_ORDER_NONE only works for reference and fixed-length
string.
3. For opaque type, the order will be ignored.
4. For compound type, all restrictions above apply to the
members.
I'll change H5Tget_order and do another commit.
There is no change to configure.in, config, and Makefile.am. There is some property change for
these files when I did a merge from 1.8.
Tested on jam. But I tested the 1.8 on heiwa, and amani.
herr_t. To minimize the change of the library's behavior, in the function
H5Z_prelude_callback of H5Z.c, if the return value of can_apply is FALSE and
the filter is MANDATE, this function returns a FAILURE. If the return value is FALSE
but the filter is OPTIONAL, this function returns a SUCCEED. During the IO, the filter
will fail and return a size of zero. But the pipeline will skip this filter.
Tested the same change for 1.8 on jam, linew, and amani. Tested on jam with szip.
a part of the h4h5tools distribution long time ago, but the INSTALL file
was not updated in the development branch and slipped into 1.8 releases and current trunk.
Description:
In certain circumstances, the direct I/O driver did not perform correctly when
data was unaligned. The driver has been patched to fix this. Also added some
potential performance improvements for the unaligned case, and strengthened the
test for whether the data needs to be aligned.
Tested: cobalt
Description:
A bug introduced in 1.8.5 causes local heap data blocks to be mis-aligned when
sizeof_offsets + 2*sizeof_lengths is not a multiple of 8. In this case, the
address of the data block as stored in the heap prefix is aligned but the actual
data block is not. This causes files created with these sizes to be corrupted,
and prevents uncorrupted files with these sizes to be unreadable. Modified
local heap code to account for alignment.
Tested: jam, amani, linew (h5committest)
Add --no-dangling-links option to h5ls.
Description:
Related to "Bug 1830 - Following an dangling external link in h5ls should set non-zero return code."
If --no-dangling-links option is specified and any dangling link is found, return exit code 1 (error).
Tested:
jam, amani and heiwa
Change h5ls not to manipulate special characters in object name or attribute name for smart display.
Description:
Related to "But1784 h5ls has input and output issues with links that have '\' characters in them."
Tested:
jam, amani and linew
Description:
Previously, the chunk cache would, when looking for a chunk, alwaylook for the
chunk in the b-tree before checking the cache. Reworked the functions that
look up chunks to always check the cache first and avoid the b-tree lookup if
the chunk is in cache.
Tested: jam, linew, amani (h5committest)
PHDF5 changed to use "mpiexec", instead of mpirun, as the default MPI
applications startup command as defined in the MPI-2 definition, section
4.1. Note that only mpich related (using mpicc command) definitions are
changed to mpiexec. Other favors like hcc, AIX, champion, are not changed
since I don't have a way to verify them yet.
Tested:
jam and amani, using both current and new mpich.
Did not h5committested since this affects PHDF5 configure only.
Support follow symbolic links.
Description:
Add '--follow-symlinks' option to follow symbolic links (soft and external).
Update help page according to RM.
Remove some warning messages from compiler.
Tested:
jam, amani and linew
Fixed a bug (1855) in H5DSattach_scale, H5DSis_attached and H5DSdetach_scale
caused by using H5Tget_native_type function to determine the native
type for reading REFERENCE_LIST attribute. The bug was exposed on Mac PPC.
Platforms tested: juniper (Mac PPC), jam, amani, linew
Rename '--follow-links' to '--follow-symlinks'
Description:
The '--follow-links' option is to follow symbolic links (soft and external).
Make the name more intuitive and specific to the feature.
Tested:
jam, amani and linew
Description:
Previously, it was possible for a chunk to be flushed due to chunk operations in
the callback from H5B_iterate in H5D_chunk_prune_by_extent. Because flushing
the chunk can force it to be reallocated if it is filtered, this can change the
contents of the chunk b-tree in the middle of H5B_iterate. Because H5B_iterate
uses a locally cached copy of the b-tree, this causes subsequent operations
to be passed incorrect data. Rewrote H5D_chunk_prune_by_extent to avoid
H5B_iterate entirely.
Also fixed a bug in the dataset expand algorithm that could cause extra chunks
to be created.
Tested: jam, linew, smirom (h5committest)
Fixed a bug in the H5DSdetach_scale function when 0 bytes
were allocated after the last reference to a dim. scale
was removed from the list of references in a VL element of the
DIMENSION_LIST attribute; modified the function to comply
with the Spec: DIMENSION_LIST attribute is deleted now when no
dimension scales left attached.
Platforms tested: jam with electric fence, amani amd linew
Add bug fixes for Tools.
Description:
Added list:
1726 - NPOESS: h5repack loses attributes for datasets of type H5T_REFERENCE
1814 - NPOESS: h5repack doesn't handle references to the groups as an
element of a dataset
1817 - h5copy fail to copy dangling link by specifying link path directly
1793 - h5ls on a non-existent file gives 0 return code
Tested:
no, just text update.
Fix memory leaks
Description
Added a routine to free memory which addresses a memory leak
when variable length strings are used as fill values.
Tested:
h5committest and valgrind (on jam/amani) to confirm freed memory.
Added notes about
+ PropList::PropList(id) pclass id/plist id
+ new DataSet::getInMemDataSize
+ CommonFG::getLinkval and CommonFG::getComment take default values
+ bugzilla 1061
+ read/write methods of DataSet and Attribute
Improve configure's large-file support control.
Description:
Modified configure to now attempt to add defines necessary for
supporting largefiles on all systems, instead of solely on linux. This
is in response to user requests to enable largefile support on Solaris
by default, as well as to give extra control on AIX (instead of just
jamming the necessary flag into the config files).
The old --enable-linux-lfs flag has been removed in favor of the
--enable-largefile flag (enabled by default), which can be used on all
platforms.
On systems where large files cannot be supported in this manner,
configure will report as such.
Tested:
h5committest
AIX (NCSA's blue_print machine)
duty, liberty, and linew.
