9 Major release removing Python 2 support. This allow both code cleanup
10 and new features, such as:
12 - Support for pathlib objects in `apply_to` and `has_extended`
13 functions when running with Python 3.6 and newer.
14 - Use of built-in C API functions for bytes/unicode/pathlib conversion
15 when dealing with file names, removing custom code (with the
18 Important API changes/bug fixes:
20 - Initialisation protocol has been changed, to disallow uninitialised
21 objects; this means that `__new__` will always create valid objects,
22 to prevent the need for checking initialisation status in all code
23 paths; this also (implicitly) fixes memory leaks on re-initialisation
24 (calling `__init__(…)` on an existing object) and segfaults (!) on
25 non-initialised object attribute access. Note ACL re-initialisation is
26 tricky and (still) leads to undefined behaviour of existing Entry
27 objects pointing to it.
28 - Fix another bug in ACL re-initialisation where failures would result
29 in invalid objects; now failed re-initialisation does not touch the
31 - Restore `__setstate__`/`__getstate__` support on Linux; this was
32 inadvertently removed due a typo(!) when adding support for it in
33 FreeBSD. Pickle should work again for ACL instances, although not sure
34 how stable this serialisation format actually is.
35 - Additionally, slightly change `__setstate__()` input to not allow
36 Unicode, since the serialisation format is an opaque binary format.
37 - Fix (and change) entry qualifier (which is a user/group ID) behaviour:
38 assume/require that uid_t/gid_t are unsigned types (they are with
39 glibc, MacOS and FreeBSD at least; the standard doesn't document the
40 signedness), and convert parsing and returning the qualifier to behave
41 accordingly. The breakage was most apparent on 32-bit architectures,
42 in which context the problem was originally reported (see issue #13).
46 - Added a `data` keyword argument to `ACL()`, which allows restoring an
47 ACL directly from a serialised form (as given by `__getstate__()`),
48 which should simplify some uses cases (`a = ACL(); a.__set
50 - When available, add the file path to I/O error messages, which should
51 lead to easier debugging.
52 - The test suite has changed to `pytest`, which allows increased
53 coverage via parameterisation.
58 *released Thu, 14 Nov 2019*
62 - Switch build system to Python 3 by default (can be overridden if
64 - Internal improvements for better cpychecker support.
65 - Fix compatibility with PyPy.
66 - Test improvements (both local and on Travis), testing more variations
68 - Improve test coverage, and allow gathering test coverage results.
69 - Drop support (well, drop testing) for Python lower than 2.7.
70 - Minor documentation improvements (closes #9, #12).
75 *released Thu, 30 Apr 2015*
79 - Enable all FreeBSD versions after 7.x at level 2 (thanks to Garrett
81 - Make test suite pass under FreeBSD, which has a stricter behaviour
82 with regards to invalid ACLs (which we do exercise in the test suite),
83 thanks again to Garret for the bug reports.
88 *released Sat, 24 May 2014*
90 No visible changes release: just fix tests when running under pypy.
95 *released Sun, 13 May 2012*
97 A bug-fix only release. Critical bugs (memory leaks and possible
98 segmentation faults) have been fixed thanks to Dave Malcolm and his
99 ``cpychecker`` tool. Additionally, some compatibility issues with Python
100 3.x have been fixed (str() methods returning bytes).
102 The documentation has been improved and changed from epydoc to sphinx;
103 note however that the documentation is still auto-generated from the
106 Project reorganisation: the project home page has been moved from
107 SourceForge to GitHub.
112 *released Sun, 27 Dec 2009*
114 Added support for Python 3.x and improved support for Unicode filenames.
119 *released Sat, 28 Jun 2008*
124 Starting with this version, pylibacl is licensed under LGPL 2.1,
125 Febryary 1999 or any later versions (see README.rst and COPYING).
130 A few more Linux-specific functions:
132 - add the ACL.equiv_mode() method, which will return the equivalent
133 octal mode if this is a basic ACL and raise an IOError exception
136 - add the acl_extended(...) function, which will check if an fd or path
142 FreeBSD 7.x will have almost all the acl manipulation functions that
143 Linux has, with the exception of __getstate__/__setstate__. As a
144 workaround, use the str() and ACL(text=...) methods to pass around
145 textual representations.
150 At module level there are now a few constants exported for easy-checking
151 at runtime what features have been compiled in:
153 - HAS_ACL_FROM_MODE, denoting whether the ACL constructor supports the
156 - HAS_ACL_CHECK, denoting whether ACL instances support the check()
159 - HAS_ACL_ENTRY, denoting whether ACL manipulation is possible and the
160 Entry and Permset classes are available
162 - HAS_EXTENEDED_CHECK, denoting whether the acl_extended function is
165 - HAS_EQUIV_MODE, denoting whether ACL instances support the
171 Many functions have now unittests, which is a good thing.
177 *released Sun, 21 Oct 2007*
182 Under Linux, implement more functions from libacl:
184 - add ACL(mode=...), implementing acl_from_mode
185 - add ACL().to_any_text, implementing acl_to_any_text
186 - add ACL comparison, using acl_cmp
187 - add ACL().check, which is a more descriptive function than validate
