Purpose: Fix rare corruption bug (HDFFV-7879)
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
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#.
Merged from HDF5 trunk r22038.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE cmake), Cmake (jam)
Bring r22053 from trunk to 1.8 branch:
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
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
Merge 1.8 and h5dump/tools and tests based on tools library from trunk.
Reduced warnings.
HDFFV-7949:
Remove duplicated functions in h5ls
Tested: local linux,h5committest
Fix for HDFFV-7836 h5diff: displays error stack message for comparing the two dangling symlink with follow-symlinks option
Description:
While ago, to improve performance, skipping same object checking
(h5tools_is_obj_same()) was added.
However the checking function doesn't understand about the dangling link and
caused the issue.
Since handling dangling link code section already implemented, move the
checking function after handling dangling-links to address the problem.
Test was 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)
Fix for HDFFV-7840 h5repack: memory leak over one of the h5diff test file
Description:
Turned out that there were two causes of memory leaks.
1. for handling variable length string in attribute.
2. for handling compound type with non-reference members.
The first issue is fixed in copy_attr() which is updated to use h5tools_detect_vlen to take care of vlen string as well as vlen data.
The second is fixed in copy_refs_attr() of compound handling code.
Merged from HDF5 trunk r21869.
Tested:
jam (linux32-LE), koala (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE cmake), Cmake (jam)
Fix for HDFFV-7838 h5ls: segfault for handling region reference in attribute with -v option
Description:
Segfault occurred when h5ls access region reference data in an attribute.
This didn't occurred when -v option was used.
The cause was "h5tool_format_t info;" struct variable members were accessed
without proper values were assigned (was NULL), so printf failed later in the code.
Merged from HDF5 trunk r21865.
Tested:
jam (linux32-LE), koala (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), , cmake-Windows (32-LE)
tely after the type was created. I'm bringing the fix from the trunk that I committed a while ago. My real changes are in test/dtypes.c, src/H5T.c, and release_docs/RELEASE.txt. All other changes are property changes.
Tested on jam. But I tested the same fix in the trunk on jam, koala, and linew.
- Update version references in RELEASE.txt
- Add reminder to HISTORY-1_8.txt that it needs the completed
RELEASE.txt from the 1.8.8 branch when it's done.
Bring r21617 from trunk to 1.8 branch:
Recalculate the size of destination attribute message when the source and
destination versions are different during an object copy operation.
(Jira: HDFF-7718)
Tested on:
Mac OS X/32 10.7.2 (amazon) w/debug
(h5committested on trunk)
Minor cleanup of RELEASE.txt:
- formatting
- update platforms tested & known issues as of 1.8.7 release
(i.e. changes made to 1_8_7's RELEASE.txt never merged to 1_8).
(these will further be updated prior to 1.8.8 release).
Tested:
- release doc only, none needed.
Bring r21561 from trunk back to 1.8 branch:
Correct error in loading local heap prefix & data block from the file.
Sometimes the local heap's prefix could be loaded before the data block (e.g.
using H5Oget_info), but then when the data block was loaded later, the free
list information would get lost, causing the heap's size to grow larger than
necessary. This is Jira bug #HDFFV-7767
Tested on:
Mac OS X/32 10.7.2 (amazon) w/debug
(h5committest coming up)
Purpose: Fix bug in H5Ocopy
Description:
H5Ocopy could get confused when copying a named datatype containing an
attribute which used that named datatype as its datatype. This happened
because H5Ocopy would recurse into the attribute's datatype before the object
the attribute was in was fully copied (i.e. before the "post-copy" pass).
Modified H5Ocopy to avoid recursing before the post-copy step in this case.
Required many changes, including to how non-committed shared messages are
copied.
Tested: jam, koala, heiwa (h5committest); durandal
