Bug Fix
Descriotion:
Removing problematic debugging code, and switching a leftover TRUE verbose
statement to FALSE in cache_common.c
Tested:
jam, liberty
Adding code to maintain a min_clean_fraction in the cache in serial mode.
Description:
The metadata cache now has the ability to maintain a min_clean_fraction
when in serial mode. The default initial cache size has been changed
from 1MB to 2MB, and the default min_clean_fraction has been set at 30%.
This check-in includes modifications to H5C.c to support maintaining a
min_clean_size, including the addition of clean_index_size and
dirty_index_size trackers, modifications to the H5C_make_space_in_cache
algorithm, as well as associated test code and additional statistics
tracking variables.
Maintaining the min_clean_fraction addresses the possibility of
experiencing a "metadata blizzard" when the cache gets completely
full with dirty entries. Upon having to make space, the cache would
previously need to flush every single entry in the cache before coming
across a clean entry which could be evicted. This resulted in unnecessary
flushing of oftentimes hot entries in the cache. Maintaining the
min_clean_fraction ensures that, when space is needed, clean entries
are more readily available to evict.
Tested:
jam, smirom, linew (h5committest)
- h5repack: When user doesn't specify a chunk size, h5repack now defines a default
chunk size as the same size of the size of the hyperslab used to read the chunks.
The size of the hyperslabs are defined as the size of each dimension or a
predefined constant, whatever is smaller. This assures that the chunk
read fits in the chunk cache. (PVN - 2008/11/21)
- H5Dset_extent: when shrinking dimensions, some chunks were not deleted.
(PVN - 2009/01/8)
Description: Added H5Pset/get_elink_cb to allow the user to specify a callback
function to be called whenever an external link is traversed. Added
H5Pset/get_elink_acc_flags to allow the user to specify the file access flags
to use to open the target file of an external link. All these properties are set on a LAPL.
Tested: jam, linew, smirom (h5committest)
Bring revision 16278 back from revise_chunks branch:
Update layout information in DCPL to unify all information in one
underlying property and switch to using H5O_layout_t for storing it, which
simplifies things considerably.
Also, fix many compiler warnings.
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
(Original patch tested on many machines)
The Tail command in jam (a newer linux) does not accept the +2l option.
It ended up wiping most of the release_doc/RELEASE.txt file contents.
Replaced the "tail +2l" by "sed -e 1d".
Tested:
Tested in Jam to verify it functions properly again.
new test program: It adds tests for several ranks, use of fill value or not, compression, different fill value allocation times, use of different storage layouts, and external files
tested: windows, linux
PG compiler complains about array out of bounds (a rank of zero was not checked)
Adding a scalar dataset to the test generator program. this case is run on a previous existing run, the case was added to 2 existing files
Tested: windows, linux
to the beginning of the file. Otherwise, the file might be re-extended later on Open VMS.
Also updated the return value for the HDlseek to be more appropriate.
Tested 1.8 on Open VMS.
Bug fix (#1357)
Description:
Three filters have not assigned correct value to one value-result argument, "buf_size". N-bit, szip, and scale offset filter have had this problem.
However, I don't think this problem has been making buffer overrun because those filters were informing the caller that the "buf", another value-result argument, is smaller than it actually is. If there was actual buffer overrun, I believe another problem exists although I don't know.
Tested:
jam, smirom, linew
Although all test were passed, I'm concerned about valgrind memcheck error. There can be another miscommunication between filter and the caller.
Moved v1 B-tree debugging routines into separate module and thinned
out header files a bit.

On Open VMS, if the last read or write put the file pointer beyond the current file size
(it happens when an object is deleted), the file can be extended when it's truncated.
Tested v1.8 on VMS.
Bug Fix
Description:
Resolved issues with broken sanity checks that were failing when the 'b2'
debugging package was enabled (v2 b-tree debugging):
- Fixed outdated assertions that would not compile. They now compile
and function correctly.
- Removed too far outdated assertions that would require too much
unnecessary refactoring of code in order to satisfy their
initial purpose.
- Re-enabled b2 debugging package when "--enable-debug=all" is
specified on the configure line.
Tested:
jam, smirom, linew

Rename the current chunk indexing routines module for B-tree indices
to better reflect their purpose, and to make the upcoming extensible array
index module fit in better.
Tested:
FreeBSD/32 6.3
Too minor to require h5committest
Description:
One open() call with O_CREAT flag did not have the third required argument.
Solution:
Added the right third argument. Also changed all open() calls to HDopen
macros for more portable coding.
Tested:
h5committested.
Description:
Recently the new source file H5EAdbkpage.c was added to the main library source code. This checkin also adds it to the Windows project files.
Note: Windows builds are still failing on the earray test, although for other reasons. I'm also looking into this.
Tested:
VS2005 on WinXP
Add support for paging large data blocks to extensible arrays
Clean up allocation/destroy code for extensible array index, super and
