9 Minor bugfix, performance and compatibility release.
11 * Minor compatibility fix: on Linux, drop the use of the `attr` library,
12 and instead switch to the glibc header `sys/xattr.h`, which is
13 provided for a really long time (since glibc 2.3). The formerly used
14 header `attr/xattr.h` has been removed from the `attr` library in
15 version 2.4.48. Fix provided by Lars Wendler, many thanks!
16 * Release the GIL when performing I/O. Patch proposed by xwhuang, many
17 thanks. I tested this a long while back it seemed to impact
18 performance on local filesystems, but upon further inspection, the
19 downsides are minor (between 0 and 5%, in many cases negligible). For
20 remote or slow filesystems, this should allow much increased
22 * Fix symlink set operation on MacOS X; bugfix provided by adamlin, much
23 appreciated! This also uncovered testing problems related to symlinks,
24 which are now fixed (the bug would be caught by the updated tests).
29 *released Mon, 23 Jan 2017*
31 Bugfix and feature release (hence the version bump).
33 The main change is to the implementation of how attributes are listed
34 and read. This was done due to existing race issues when attributes are
35 modified while being read (github issue #12), but basically all various
36 internal paths that dealt with retrieving an attribute value or listing
37 attributes were unified in a single helper function that does handle
38 such concurrent modifications. As a side effect, the size of the buffers
39 used for such reads have changed, which (depending on attribute value)
40 might change the trade-off between number of syscalls done and memory
43 As feature release, OSX support was contributed by Adam Knight
44 <adam@movq.us>, thanks a lot! I don't have access to OSX so the testing
45 for it is done via Travis builds; please report any issues.
50 *released Sat, 09 Apr 2016*
54 * Fixes some sign-compare warnings
55 * Fixes potential name truncation in merge_ns()
56 * Fixes building on systems which don't have ENODATA
58 Tested with Python 2.7.11, Python 3.5.1 and PyPy 5.0.1.
63 *released Fri, 01 May 2015*
67 * fixes some more memory leaks when handling out-of-memory in get_all()
69 * improve error reporting when an attribute disappears after we asked
70 for its length but before we managed to read it
71 * fix int/size_t issues found by RedHat/Fedora,
72 https://bugzilla.redhat.com/show_bug.cgi?id=1127310; the fix is
73 different than their fix, but it should accomplish the same thing
74 * convert all code to only do explicit casts after checking boundaries,
75 making the code `-Wconversion`-clean (although that warning is not
81 *released Thu, 30 Apr 2015*
83 Fix memory leaks on some of the error-handling paths of the `get()`
89 *released Fri, 23 May 2014*
91 Small optimisations release:
93 * ari edelkind contributed a speed-up optimisation for handling of files
94 without xattrs (which is, in general, the expected case)
95 * Jonas Borgström contributed a behaviour change to the handling of file
96 names: under Python 3 and up, unicode paths are encoded/decoded using
97 the 'surogatee' handler, instead of the 'strict' handler; while this
98 can hide encoding errors, it mirrors what Python libraries do
99 (e.g. see os.fsencode/fsdecode)
100 * Sean Patrick Santos contributed improvements to the test suite so that
101 it can be used even on files systems which have built-in attributes
102 (e.g. when using SELinux, or NFSv4); to enable this, define the
103 attributes in the TEST_IGNORE_XATTRS environment variable
108 *released Thu, 03 Jan 2013*
110 Bug-fix release. Thanks to Michał Górny, it looked like the library had
111 problem running under pypy, but actually there was a bug in the
112 PyArg_ParseTuple use of et# (signed vs. unsigned, and lack of compiler
113 warnings). This was fixed, and now the test suite passed with many
114 CPython versions and PyPy (version 1.9).
119 *released Wed, 16 May 2012*
121 Bug-fix release. Thanks to Dave Malcolm and his cpychecker tool, a
122 number of significant bugs (refcount leaks and potential NULL-pointer
123 dereferences) have been fixed.
125 Furthermore, compatibility with Python 3 has been improved; this however
126 required changing the meaning of the ``namespace`` argument to the
127 functions: if passed, None is no longer a valid value; pass an empty
128 string if (due to the structure of your program) you have to pass this
129 argument but want to specify no namespace.
131 Also, the project home page has changed from SourceForge to GitHub, and
132 the documentation has been converted from epydoc-based to sphinx.
138 *released Sun, 27 Dec 2009*
140 Implemented support for Python 3. This required a significant change to
141 the C module, hence the new version number.
146 *released Mon, 30 Jun 2008*
151 The old functions ({get,set,list,remove}xattr) are deprecated and replaced with
152 a new API that is namespace-aware and hopefully will allow other OSes (e.g.
153 FreeBSD) to be supported more naturally.
155 Both the old and the new API are supported in the 0.4 versions, however users
156 are encouraged to migrate to the new API.
161 A new bulk get function called get_all() has been added that should be somewhat
162 faster in case of querying files which have many attributes.
167 Since LGPLv3 is not compatible with GPLv2 (which unfortunately I didn't realize
168 before), the license was changed to LGPLv2.1 or later.
173 Unittest coverage was improved.
178 *released Sun, 09 Mar 2008*
180 * changed licence from GPL to LGPL (3 or later)
181 * changed listxattr return type from tuple to a list
182 * developer-related: added unittests
187 *released Sun, 01 Jul 2007*
189 * fixed listing symlink xattrs
194 *released Sat, 11 Feb 2006*
196 * fixed a bug when reading symlink EAs (you weren't able to
198 * fixed a possible memory leak when the actual read of the EA
199 failed but the call to get the length of the EA didn't
