7 *released Mon, 23 Jan 2017*
9 Bugfix and feature release (hence the version bump).
11 The main change is to the implementation of how attributes are listed
12 and read. This was done due to existing race issues when attributes are
13 modified while being read (github issue #12), but basically all various
14 internal paths that dealt with retrieving an attribute value or listing
15 attributes were unified in a single helper function that does handle
16 such concurrent modifications. As a side effect, the size of the buffers
17 used for such reads have changed, which (depending on attribute value)
18 might change the trade-off between number of syscalls done and memory
21 As feature release, OSX support was contributed by Adam Knight
22 <adam@movq.us>, thanks a lot! I don't have access to OSX so the testing
23 for it is done via Travis builds; please report any issues.
28 *released Sat, 09 Apr 2016*
32 * Fixes some sign-compare warnings
33 * Fixes potential name truncation in merge_ns()
34 * Fixes building on systems which don't have ENODATA
36 Tested with Python 2.7.11, Python 3.5.1 and PyPy 5.0.1.
41 *released Fri, 01 May 2015*
45 * fixes some more memory leaks when handling out-of-memory in get_all()
47 * improve error reporting when an attribute disappears after we asked
48 for its length but before we managed to read it
49 * fix int/size_t issues found by RedHat/Fedora,
50 https://bugzilla.redhat.com/show_bug.cgi?id=1127310; the fix is
51 different than their fix, but it should accomplish the same thing
52 * convert all code to only do explicit casts after checking boundaries,
53 making the code `-Wconversion`-clean (although that warning is not
59 *released Thu, 30 Apr 2015*
61 Fix memory leaks on some of the error-handling paths of the `get()`
67 *released Fri, 23 May 2014*
69 Small optimisations release:
71 * ari edelkind contributed a speed-up optimisation for handling of files
72 without xattrs (which is, in general, the expected case)
73 * Jonas Borgström contributed a behaviour change to the handling of file
74 names: under Python 3 and up, unicode paths are encoded/decoded using
75 the 'surogatee' handler, instead of the 'strict' handler; while this
76 can hide encoding errors, it mirrors what Python libraries do
77 (e.g. see os.fsencode/fsdecode)
78 * Sean Patrick Santos contributed improvements to the test suite so that
79 it can be used even on files systems which have built-in attributes
80 (e.g. when using SELinux, or NFSv4); to enable this, define the
81 attributes in the TEST_IGNORE_XATTRS environment variable
86 *released Thu, 03 Jan 2013*
88 Bug-fix release. Thanks to Michał Górny, it looked like the library had
89 problem running under pypy, but actually there was a bug in the
90 PyArg_ParseTuple use of et# (signed vs. unsigned, and lack of compiler
91 warnings). This was fixed, and now the test suite passed with many
92 CPython versions and PyPy (version 1.9).
97 *released Wed, 16 May 2012*
99 Bug-fix release. Thanks to Dave Malcolm and his cpychecker tool, a
100 number of significant bugs (refcount leaks and potential NULL-pointer
101 dereferences) have been fixed.
103 Furthermore, compatibility with Python 3 has been improved; this however
104 required changing the meaning of the ``namespace`` argument to the
105 functions: if passed, None is no longer a valid value; pass an empty
106 string if (due to the structure of your program) you have to pass this
107 argument but want to specify no namespace.
109 Also, the project home page has changed from SourceForge to GitHub, and
110 the documentation has been converted from epydoc-based to sphinx.
116 *released Sun, 27 Dec 2009*
118 Implemented support for Python 3. This required a significant change to
119 the C module, hence the new version number.
124 *released Mon, 30 Jun 2008*
129 The old functions ({get,set,list,remove}xattr) are deprecated and replaced with
130 a new API that is namespace-aware and hopefully will allow other OSes (e.g.
131 FreeBSD) to be supported more naturally.
133 Both the old and the new API are supported in the 0.4 versions, however users
134 are encouraged to migrate to the new API.
139 A new bulk get function called get_all() has been added that should be somewhat
140 faster in case of querying files which have many attributes.
145 Since LGPLv3 is not compatible with GPLv2 (which unfortunately I didn't realize
146 before), the license was changed to LGPLv2.1 or later.
151 Unittest coverage was improved.
156 *released Sun, 09 Mar 2008*
158 * changed licence from GPL to LGPL (3 or later)
159 * changed listxattr return type from tuple to a list
160 * developer-related: added unittests
165 *released Sun, 01 Jul 2007*
167 * fixed listing symlink xattrs
172 *released Sat, 11 Feb 2006*
174 * fixed a bug when reading symlink EAs (you weren't able to
176 * fixed a possible memory leak when the actual read of the EA
177 failed but the call to get the length of the EA didn't
