Fix for HDFFV-7837 - h5diff: incorrect behavior with exclude-path option when unique object exist only in one file
Description:
If unique objects exists only in one file and try to exclude
the unique objects with --exclude-path option, h5diff missed
excluding some objects.
Fixed to exclude objects correctly in such case.
Test cases were added and tagged with jira#.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE cmake), Cmake (jam)
Minor code safety issue in test/fheap.c and whitespace in other files.
Tested on:
Mac OSX/64 10.7.3 (amazon) w/debug
(Too minor to require h5committest)
HDFFV-7523 JPSS: h5dump fails to open an attribute when using the -a option to specify an attribute with a slash in the name
Description:
Update command line help page and test generating file.
Previous commits: r22052, r22063
Tested:
jam (linux32-LE), koala (linux64-LE), cmake (jam)
This occurs due to the istore test creating very large files on systems which
do not have POSIX-like sparse file semantics. The large amount of I/O causes
the test to run for a very long period of time.
The fix was to copy the "big" test's sparse file check and only run the
largest sparse file test when POSIX-like sparse file semantics are found.
Tested on:
jam (nfs)
ostrich (nfs)
loyalty (ufs)
64-bit linux VM (ext4)
64-bit OS-X Lion (hfs, detected as not POSIX sparse)
64-bit Windows 7 (NTFS, detected as not POSIX sparse)
The OS-X failure to pass the sparse check is likely an error and will be
entered as a new bug.
The parser mistaked "-" as substraction. I fixed it and also fixed another problem
with some special cases like 100-x and 2/x.
Tested on jam, koala, and ostrich.
Description:
When using the new object header format, it was possible for corruption to occur
if the first object header chunk changed size such that the lenght of the "chunk
0 size" field changed. This only occurred if there were messages that had not
been decoded. The original algorithm that changed the object header chunk size
marked all messages as dirty, causing those that had not been decoded to have
both the raw and native form invalidated. Changed the algorithm to avoid
marking messages dirty and added assertions to catch the case where messages
are dirtied without being decoded (or recently created) first.
Tested: jam, koala, ostrich (h5committest), durandal
Description:
When using the new object header format and adding an attribute with a size near
64K, it was possible for file corruption to occur. This happened only if the
first object header chunk was smaller than 256 bytes and then grew to larger
than 64K after the attribute was added.
Tested: ostrich, jam, koala (h5committest), durandal
Correct corner case for creating a contiguous dataset with a zero-sized
dataspace, when the allocation time is set to early.
Also clean up a few compiler warnings in the dataspace code.
Tested on:
Mac OSX/64 10.7.3 (amazon) w/debug & parallel
by using an escape character. For example, for a dataset "/dset"
containing attribute "speed(m/h)", use "h5dump -a "/dset/speed(\/h)"
to show the content of the attribute. See details at HDFFV-7523
Fix for HDFFV-7835 h5diff: incorrect result for comparing the two same type symlinks as dangling links.
Description:
When two symbolic dangling links are compared with --follow-symlinks option,
the result should be same. It works for comparing two files, but didn't work
for comparing two objects.
Test cases were added and tagged with jira#.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE cmake), Cmake (jam)
HDFFV-7602 - GMQS: HDF5 command tools: Provide framework for reusable test files among tools
Stage2 working for h5ls tool.
Description:
Update cmake script to fetch test files from any tools to a test directory
and run test in organized manner.
Also keep the apperance similiar to shell script for better maintainance.
Tested:
CMake (Windows and jam)
If a link is specified on the command with the -d option, call the handle_links function on error from the H5Dopen command.
Updated test file results with error stack when link not found.
Tested: local linux and jam
Task for HDFFV-7862 - Select data by chunk direction to improve performance in h5repack
Description:
h5repack sometimes became very slow when handling big chunked datasets in
certain cases. (when chunk boundary doesn't match with a hyperslab boundary.)
The main issue was from figuring out a hypeslab without considering chunk
boundary to read from and write to such datasets.
The update was made to figure out a better hyperslab unit with considering
chunk boundary to improve performance for such cases prior to the update.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows
