Description:
The core file driver previously matched files only based on the name used to
open them, even when a backing store is used. This caused problems in the
failing test when it traversed an external link to itself, and did not recognize
that it was the same file. Similar tests in links.c were skipped when the core
file driver was used. The failure was previously masked by inappropriate file
flushes caused by external link traversal. Added code to the core file driver
to keep track of low level file information of the backings store to allow for
accurate recognition of duplicate files. Also re-enabled all links.c tests for
the core file driver.
Tested: Fedora (core and sec2 drivers; no time for full commit test, will
monitor daily tests)
Description:
Support for expanding external links was not implemented in H5Ocopy, even though
a flag existed for H5Pset_copy_object to enable this. This patch implements
this feature.
Tested: jam, amani, linew (h5committest); Fedora
Description:
Previously, the library would reopen the source file when traversing an external
link if unable to find the target file otherwise. This has been corrected.
Also moved the call to H5F_flush from H5F_try_close to H5F_dest, so the file is
only flushed when the last identifier for the file is closed. This prevernts
situations where the library could attempt to flush a file with protected
metadata.
Tested: jam, amani, linew (h5committest); Fedora
Work for bugzilla 1754: h5diff: support comparing through links.
Description:
merged from hdf5 trunk (18164, 18165, 18166, 18167, 18170, 18266, 18273)
Tested:
h5committest (jam, amani and linew)
Description:
In certain cases, removal of an object in a v1 b-tree would cause the leftmost
key in the right neighbor to be overwritten. While this did not pose a problem
for group b-trees, with chunked datasets it would overwrite the offset value
of the neighbor's leftmost child, causing corruption. Reworked the code to
differentiate between b-trees whose children are fundamentally associated with
their left key and those who are associated with their right key.
Tested: jam, linew, amani (h5committest)
Bring r17939 from trunk to 1.8 branch:
Handle external links from symlinked files by adding another check to
look for "child" files for links from the actual location of the "parent" file,
instead of from the location of the symlink.
Tested on:
FreeBSD/32 6.3 (duty)
(h5committested on trunk)
Fix Bug1672 - Display garbage value on LE machine for BE data.
Description:
Casuing by calling diff_dataset twice when -r or no option was given.
Change to call it once which fix the problem.
It also improves the performance. (diffing time in half)
According further test, it also occurred on BE machine as well and it
seems occruing only with the BE data attached to Bugzilla.
Don't know how the file was created. Anyway this fix will prevent
from diffing with garbage values in similiar potential case.
Tested on:
linux32 (jam) , linux64 (almani), solaris (linew)
Merge from Trunk
Description:
Merging all of my CFLAGS-related changes from trunk to 1.8
This includes revision #s: 17616, 17625, 17627, 17639, and 17643.
Tested:
h5committest and some additional checks on our FreeBSD as well
as NCSA's machines.
Bring r17624 from trunk to 1.8 branch:
Don't allow reads to change or add to the metadata accumulator, since
they might be speculative and could bring raw data into the metadata
accumulator.
