5 *released Sun, 23 Apr 2023*
7 Important: Python 3.7 is the minimum supported version, due to
8 difficulty of testing old releases, and the fact that everything older
9 has been deprecated a long time ago (e.g. 3.6 at the end of 2021).
11 Otherwise, a minor release:
13 - Improve error handling in some corner cases (not expected to have
14 any real-life impact, but who knows).
15 - Improved testing coverage and test infrastructure.
16 - Modernise parts of the C code based on recent Python version
18 - Add a simple security policy and contribution guidelines.
22 *released Sun, 29 Nov 2020*
24 Major release removing Python 2 support. This allow both code cleanup
25 and new features, such as:
27 - Support for pathlib objects in `apply_to` and `has_extended`
28 functions when running with Python 3.6 and newer.
29 - Use of built-in C API functions for bytes/unicode/pathlib conversion
30 when dealing with file names, removing custom code (with the
33 Important API changes/bug fixes:
35 - Initialisation protocol has been changed, to disallow uninitialised
36 objects; this means that `__new__` will always create valid objects,
37 to prevent the need for checking initialisation status in all code
38 paths; this also (implicitly) fixes memory leaks on re-initialisation
39 (calling `__init__(…)` on an existing object) and segfaults (!) on
40 non-initialised object attribute access. Note ACL re-initialisation is
41 tricky and (still) leads to undefined behaviour of existing Entry
42 objects pointing to it.
43 - Fix another bug in ACL re-initialisation where failures would result
44 in invalid objects; now failed re-initialisation does not touch the
46 - Restore `__setstate__`/`__getstate__` support on Linux; this was
47 inadvertently removed due a typo(!) when adding support for it in
48 FreeBSD. Pickle should work again for ACL instances, although not sure
49 how stable this serialisation format actually is.
50 - Additionally, slightly change `__setstate__()` input to not allow
51 Unicode, since the serialisation format is an opaque binary format.
52 - Fix (and change) entry qualifier (which is a user/group ID) behaviour:
53 assume/require that uid_t/gid_t are unsigned types (they are with
54 glibc, MacOS and FreeBSD at least; the standard doesn't document the
55 signedness), and convert parsing and returning the qualifier to behave
56 accordingly. The breakage was most apparent on 32-bit architectures,
57 in which context the problem was originally reported (see issue #13).
61 - Added a `data` keyword argument to `ACL()`, which allows restoring an
62 ACL directly from a serialised form (as given by `__getstate__()`),
63 which should simplify some uses cases (`a = ACL(); a.__set
65 - When available, add the file path to I/O error messages, which should
66 lead to easier debugging.
67 - The test suite has changed to `pytest`, which allows increased
68 coverage via parameterisation.
72 *released Thu, 14 Nov 2019*
76 - Switch build system to Python 3 by default (can be overridden if
78 - Internal improvements for better cpychecker support.
79 - Fix compatibility with PyPy.
80 - Test improvements (both local and on Travis), testing more variations
82 - Improve test coverage, and allow gathering test coverage results.
83 - Drop support (well, drop testing) for Python lower than 2.7.
84 - Minor documentation improvements (closes #9, #12).
88 *released Thu, 30 Apr 2015*
92 - Enable all FreeBSD versions after 7.x at level 2 (thanks to Garrett
94 - Make test suite pass under FreeBSD, which has a stricter behaviour
95 with regards to invalid ACLs (which we do exercise in the test suite),
96 thanks again to Garret for the bug reports.
100 *released Sat, 24 May 2014*
102 No visible changes release: just fix tests when running under pypy.
106 *released Sun, 13 May 2012*
108 A bug-fix only release. Critical bugs (memory leaks and possible
109 segmentation faults) have been fixed thanks to Dave Malcolm and his
110 ``cpychecker`` tool. Additionally, some compatibility issues with Python
111 3.x have been fixed (str() methods returning bytes).
113 The documentation has been improved and changed from epydoc to sphinx;
114 note however that the documentation is still auto-generated from the
117 Project reorganisation: the project home page has been moved from
118 SourceForge to GitHub.
122 *released Sun, 27 Dec 2009*
124 Added support for Python 3.x and improved support for Unicode filenames.
128 *released Sat, 28 Jun 2008*
133 Starting with this version, pylibacl is licensed under LGPL 2.1,
134 Febryary 1999 or any later versions (see README.rst and COPYING).
138 A few more Linux-specific functions:
140 - add the ACL.equiv_mode() method, which will return the equivalent
141 octal mode if this is a basic ACL and raise an IOError exception
144 - add the acl_extended(...) function, which will check if an fd or path
149 FreeBSD 7.x will have almost all the acl manipulation functions that
150 Linux has, with the exception of __getstate__/__setstate__. As a
151 workaround, use the str() and ACL(text=...) methods to pass around
152 textual representations.
156 At module level there are now a few constants exported for easy-checking
157 at runtime what features have been compiled in:
159 - `HAS_ACL_FROM_MODE`, denoting whether the ACL constructor supports
160 the `mode=0xxx` parameter
162 - `HAS_ACL_CHECK`, denoting whether ACL instances support the
165 - `HAS_ACL_ENTRY`, denoting whether ACL manipulation is possible and
166 the Entry and Permset classes are available
168 - `HAS_EXTENEDED_CHECK`, denoting whether the `acl_extended()`
169 function is supported
171 - `HAS_EQUIV_MODE`, denoting whether ACL instances support the
172 `equiv_mode()` method
176 Many functions have now unittests, which is a good thing.
181 *released Sun, 21 Oct 2007*
185 Under Linux, implement more functions from libacl:
187 - add `ACL(mode=...)`, implementing `acl_from_mode`.
188 - add `ACL.to_any_text()`, implementing `acl_to_any_text`.
189 - add ACL comparison, using `acl_cmp`.
190 - add `ACL.check()`, which is a more descriptive function than
