9 Typo fix release in the bug tracker link :/
14 *released Tue, 26 Nov 2019*
16 Major change: drop compatibility with Python 2, which allows significant
21 * Switch internal implementation of argument parsing to a built-in one
22 (`PyUnicode_FSConverter`), which brings automatic support for
23 path-like objects in Python 3.6+ (#20), and also a more uniform
24 handling of Unicode path arguments with respect to other Python code.
25 * Fix missing error check in list operations in `get_all` (#17).
26 * Switch test library to pytest; not that a reasonable recent version is
27 needed. Additionally, expand test coverage, although not directly
28 visible in actual coverage reports…
33 *released Tue, 24 Jul 2018*
35 Minor bugfix, performance and compatibility release.
37 * Minor compatibility fix: on Linux, drop the use of the `attr` library,
38 and instead switch to the glibc header `sys/xattr.h`, which is
39 provided for a really long time (since glibc 2.3). The formerly used
40 header `attr/xattr.h` has been removed from the `attr` library in
41 version 2.4.48. Fix provided by Lars Wendler, many thanks!
42 * Release the GIL when performing I/O. Patch proposed by xwhuang, many
43 thanks. I tested this a long while back it seemed to impact
44 performance on local filesystems, but upon further inspection, the
45 downsides are minor (between 0 and 5%, in many cases negligible). For
46 remote or slow filesystems, this should allow much increased
48 * Fix symlink set operation on MacOS X; bugfix provided by adamlin, much
49 appreciated! This also uncovered testing problems related to symlinks,
50 which are now fixed (the bug would be caught by the updated tests).
55 *released Mon, 23 Jan 2017*
57 Bugfix and feature release (hence the version bump).
59 The main change is to the implementation of how attributes are listed
60 and read. This was done due to existing race issues when attributes are
61 modified while being read (github issue #12), but basically all various
62 internal paths that dealt with retrieving an attribute value or listing
63 attributes were unified in a single helper function that does handle
64 such concurrent modifications. As a side effect, the size of the buffers
65 used for such reads have changed, which (depending on attribute value)
66 might change the trade-off between number of syscalls done and memory
69 As feature release, OSX support was contributed by Adam Knight
70 <adam@movq.us>, thanks a lot! I don't have access to OSX so the testing
71 for it is done via Travis builds; please report any issues.
76 *released Sat, 09 Apr 2016*
80 * Fixes some sign-compare warnings
81 * Fixes potential name truncation in merge_ns()
82 * Fixes building on systems which don't have ENODATA
84 Tested with Python 2.7.11, Python 3.5.1 and PyPy 5.0.1.
89 *released Fri, 01 May 2015*
93 * fixes some more memory leaks when handling out-of-memory in get_all()
95 * improve error reporting when an attribute disappears after we asked
96 for its length but before we managed to read it
97 * fix int/size_t issues found by RedHat/Fedora,
98 https://bugzilla.redhat.com/show_bug.cgi?id=1127310; the fix is
99 different than their fix, but it should accomplish the same thing
100 * convert all code to only do explicit casts after checking boundaries,
101 making the code `-Wconversion`-clean (although that warning is not
107 *released Thu, 30 Apr 2015*
109 Fix memory leaks on some of the error-handling paths of the `get()`
115 *released Fri, 23 May 2014*
117 Small optimisations release:
119 * ari edelkind contributed a speed-up optimisation for handling of files
120 without xattrs (which is, in general, the expected case)
121 * Jonas Borgström contributed a behaviour change to the handling of file
122 names: under Python 3 and up, unicode paths are encoded/decoded using
123 the 'surogatee' handler, instead of the 'strict' handler; while this
124 can hide encoding errors, it mirrors what Python libraries do
125 (e.g. see os.fsencode/fsdecode)
126 * Sean Patrick Santos contributed improvements to the test suite so that
127 it can be used even on files systems which have built-in attributes
128 (e.g. when using SELinux, or NFSv4); to enable this, define the
129 attributes in the TEST_IGNORE_XATTRS environment variable
134 *released Thu, 03 Jan 2013*
136 Bug-fix release. Thanks to Michał Górny, it looked like the library had
137 problem running under pypy, but actually there was a bug in the
138 PyArg_ParseTuple use of et# (signed vs. unsigned, and lack of compiler
139 warnings). This was fixed, and now the test suite passed with many
140 CPython versions and PyPy (version 1.9).
145 *released Wed, 16 May 2012*
147 Bug-fix release. Thanks to Dave Malcolm and his cpychecker tool, a
148 number of significant bugs (refcount leaks and potential NULL-pointer
149 dereferences) have been fixed.
151 Furthermore, compatibility with Python 3 has been improved; this however
152 required changing the meaning of the ``namespace`` argument to the
153 functions: if passed, None is no longer a valid value; pass an empty
154 string if (due to the structure of your program) you have to pass this
155 argument but want to specify no namespace.
157 Also, the project home page has changed from SourceForge to GitHub, and
158 the documentation has been converted from epydoc-based to sphinx.
164 *released Sun, 27 Dec 2009*
166 Implemented support for Python 3. This required a significant change to
167 the C module, hence the new version number.
172 *released Mon, 30 Jun 2008*
177 The old functions ({get,set,list,remove}xattr) are deprecated and replaced with
178 a new API that is namespace-aware and hopefully will allow other OSes (e.g.
179 FreeBSD) to be supported more naturally.
181 Both the old and the new API are supported in the 0.4 versions, however users
182 are encouraged to migrate to the new API.
187 A new bulk get function called get_all() has been added that should be somewhat
188 faster in case of querying files which have many attributes.
193 Since LGPLv3 is not compatible with GPLv2 (which unfortunately I didn't realize
194 before), the license was changed to LGPLv2.1 or later.
199 Unittest coverage was improved.
204 *released Sun, 09 Mar 2008*
206 * changed licence from GPL to LGPL (3 or later)
207 * changed listxattr return type from tuple to a list
208 * developer-related: added unittests
213 *released Sun, 01 Jul 2007*
215 * fixed listing symlink xattrs
220 *released Sat, 11 Feb 2006*
222 * fixed a bug when reading symlink EAs (you weren't able to
224 * fixed a possible memory leak when the actual read of the EA
225 failed but the call to get the length of the EA didn't
