5 *released Fri, 14 Feb 2025*
7 Minor version, with a few test improvements, and updated documentation
8 building dependencies. No user-visible changes otherwise.
10 Tested with CPython versions 3.7-3.13, and PyPy 3.7-3.10.
14 *released Sun, 23 Apr 2023*
16 Important: Python 3.7 is the minimum supported version, due to
17 difficulty of testing old releases, and the fact that everything older
18 has been deprecated a long time ago (e.g. 3.6 at the end of 2021).
20 Otherwise, a minor release:
22 - Improve error handling in some corner cases (not expected to have
23 any real-life impact, but who knows).
24 - Improved testing coverage and test infrastructure.
25 - Modernise parts of the C code based on recent Python version
27 - Add a simple security policy and contribution guidelines.
31 *released Sun, 29 Nov 2020*
33 Major release removing Python 2 support. This allow both code cleanup
34 and new features, such as:
36 - Support for pathlib objects in `apply_to` and `has_extended`
37 functions when running with Python 3.6 and newer.
38 - Use of built-in C API functions for bytes/unicode/pathlib conversion
39 when dealing with file names, removing custom code (with the
42 Important API changes/bug fixes:
44 - Initialisation protocol has been changed, to disallow uninitialised
45 objects; this means that `__new__` will always create valid objects,
46 to prevent the need for checking initialisation status in all code
47 paths; this also (implicitly) fixes memory leaks on re-initialisation
48 (calling `__init__(…)` on an existing object) and segfaults (!) on
49 non-initialised object attribute access. Note ACL re-initialisation is
50 tricky and (still) leads to undefined behaviour of existing Entry
51 objects pointing to it.
52 - Fix another bug in ACL re-initialisation where failures would result
53 in invalid objects; now failed re-initialisation does not touch the
55 - Restore `__setstate__`/`__getstate__` support on Linux; this was
56 inadvertently removed due a typo(!) when adding support for it in
57 FreeBSD. Pickle should work again for ACL instances, although not sure
58 how stable this serialisation format actually is.
59 - Additionally, slightly change `__setstate__()` input to not allow
60 Unicode, since the serialisation format is an opaque binary format.
61 - Fix (and change) entry qualifier (which is a user/group ID) behaviour:
62 assume/require that uid_t/gid_t are unsigned types (they are with
63 glibc, MacOS and FreeBSD at least; the standard doesn't document the
64 signedness), and convert parsing and returning the qualifier to behave
65 accordingly. The breakage was most apparent on 32-bit architectures,
66 in which context the problem was originally reported (see issue #13).
70 - Added a `data` keyword argument to `ACL()`, which allows restoring an
71 ACL directly from a serialised form (as given by `__getstate__()`),
72 which should simplify some uses cases (`a = ACL(); a.__set
74 - When available, add the file path to I/O error messages, which should
75 lead to easier debugging.
76 - The test suite has changed to `pytest`, which allows increased
77 coverage via parameterisation.
81 *released Thu, 14 Nov 2019*
85 - Switch build system to Python 3 by default (can be overridden if
87 - Internal improvements for better cpychecker support.
88 - Fix compatibility with PyPy.
89 - Test improvements (both local and on Travis), testing more variations
91 - Improve test coverage, and allow gathering test coverage results.
92 - Drop support (well, drop testing) for Python lower than 2.7.
93 - Minor documentation improvements (closes #9, #12).
97 *released Thu, 30 Apr 2015*
101 - Enable all FreeBSD versions after 7.x at level 2 (thanks to Garrett
103 - Make test suite pass under FreeBSD, which has a stricter behaviour
104 with regards to invalid ACLs (which we do exercise in the test suite),
105 thanks again to Garret for the bug reports.
109 *released Sat, 24 May 2014*
111 No visible changes release: just fix tests when running under pypy.
115 *released Sun, 13 May 2012*
117 A bug-fix only release. Critical bugs (memory leaks and possible
118 segmentation faults) have been fixed thanks to Dave Malcolm and his
119 ``cpychecker`` tool. Additionally, some compatibility issues with Python
120 3.x have been fixed (str() methods returning bytes).
122 The documentation has been improved and changed from epydoc to sphinx;
123 note however that the documentation is still auto-generated from the
126 Project reorganisation: the project home page has been moved from
127 SourceForge to GitHub.
131 *released Sun, 27 Dec 2009*
133 Added support for Python 3.x and improved support for Unicode filenames.
137 *released Sat, 28 Jun 2008*
142 Starting with this version, pylibacl is licensed under LGPL 2.1,
143 Febryary 1999 or any later versions (see README.rst and COPYING).
147 A few more Linux-specific functions:
149 - add the ACL.equiv_mode() method, which will return the equivalent
150 octal mode if this is a basic ACL and raise an IOError exception
153 - add the acl_extended(...) function, which will check if an fd or path
158 FreeBSD 7.x will have almost all the acl manipulation functions that
159 Linux has, with the exception of __getstate__/__setstate__. As a
160 workaround, use the str() and ACL(text=...) methods to pass around
161 textual representations.
165 At module level there are now a few constants exported for easy-checking
166 at runtime what features have been compiled in:
168 - `HAS_ACL_FROM_MODE`, denoting whether the ACL constructor supports
169 the `mode=0xxx` parameter
171 - `HAS_ACL_CHECK`, denoting whether ACL instances support the
174 - `HAS_ACL_ENTRY`, denoting whether ACL manipulation is possible and
175 the Entry and Permset classes are available
177 - `HAS_EXTENEDED_CHECK`, denoting whether the `acl_extended()`
178 function is supported
180 - `HAS_EQUIV_MODE`, denoting whether ACL instances support the
181 `equiv_mode()` method
185 Many functions have now unittests, which is a good thing.
190 *released Sun, 21 Oct 2007*
194 Under Linux, implement more functions from libacl:
196 - add `ACL(mode=...)`, implementing `acl_from_mode`.
197 - add `ACL.to_any_text()`, implementing `acl_to_any_text`.
198 - add ACL comparison, using `acl_cmp`.
199 - add `ACL.check()`, which is a more descriptive function than
