I've also added and documented two new OS X specific file flags: UF_HIDDEN and UF_COMPRESSED.

Ronald Oussoren ronaldousso...@mac.com added the comment: Tests for the posix module should go in test_posix. The name 'posix' is used very loosely in python, it is basicly used as an alias for 'unixy'. I'm not too happy about replicating the definition of the flags, as Ned noted the flags are also defined in Lib/stat.py. I'd keep them out of posixmodule as the current definitions in Lib/stat.py should be valid on all platforms that currently support these flags. W.r.t testing: there should be some simple smoke tests, basicly just enough to ensure that the function is available and that it links up to the right system call. There is no need to perform un exhaustive test of the system call, that should be done by the os vendor. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8746 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Garrett Cooper yaneg...@gmail.com added the comment: *NOUNLINK was not implemented by OSX, so there's actually a bug with the compile tests if you take that into consideration. And again, only FreeBSD defines *NOUNLINK. The other BSDs, not so much. As far as the reason why I implemented the flags, the documentation that I was looking at didn't implement those flags. I looked at the latest documentation and it appears to be correct though. I will implement tests for *UNLINK and *HIDDEN (FWIW the tests I wrote are ok for cross-compilation because they just test for the existence of the values -- they don't test to ensure that the functionality is correct, like some of the logic in configure was recently `fixed' to do). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8746 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Ned Deily n...@acm.org added the comment: Actually the flags do already exist: note (as defined in the stat module) (http://docs.python.org/py3k/library/os.html#os.chflags). Other than the new UF_HIDDEN, it looks like they are all hardwired there in Lib/stat.py. There is something to be said for the approach in your patch in that it guarantees that the flags match the build OS definitions; the downside is some lack of portability and cross-testing. Considering that there are other stat flags in there and have been for a long time, I'd be inclined to not change things other than throwing in UF_HIDDEN. Regarding testing, perhaps the single most important thing would be to add a test that os.chflags is in fact present on systems where it is expected (to catch any future build problems like the one in this issue). As you say, these are relatively transparent wrappers and we have to accept the OS's implementation. Testing for the presence of os.lchflags is a bit trickier in that on OS X it should only be present if Python was built with a MACOSX_DEPLOYMENT_TARGET of 10.5 or higher. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8746 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8746] os.chflags() and os.lchflags() are not built when they should be be
Ned Deily n...@acm.org added the comment:
Thanks Garrett for reporting the problem and thank Nick for the patches. It
turns out the problem is more involved though the solution is similar. I've
spent some time figuring out what went wrong here and documenting it in this
issue so that no one else has to. Ugh.
The relevant checkin events:
(1) (2009-07-16) r74038 changed the autoconf tests for chflags and lchflags to
be m4a double-quoted (from '[' to '[[') to ensure they don't get mangled.
The test continues to use the AC_TRY_RUN macro and is working correctly.
(2) (2009-11-02) r76050 checked in a modified version of a patch from Gentoo to
help support cross-compiling. The original patch was against a pre-r74038
version; it wrapped the AC_TRY_RUN macro in an AC_CACHE_CHECK and a layer of
quotes. In updating the patch for the then-current trunk (2.7), the
significance of the r74038 change was apparently overlooked, resulting in an
extra and faulty level of [...] quotes which end up in the configure test C
source. The test now gets compile errors on all Unix-y platforms but it is
only significant on those that do support chflags and/or lchflags, i.e. BSD
ones and OS X.
(3) (2010-01-30) The buggy test from trunk is merged into py3k (3.2) r77862,
3.1 r77863, and 2.6 r77864.
(4) (2010-05-08) As part of Issue8510 updates to configure.in to work with
autoconf 2.65, r80478 for py3k (3.2) and r80969 for trunk (2.7) converted the
AC_TRY_RUN macro calls to ones using AC_RUN_IFELSE and AC_LANG_SOURCE. An extra
level of quoting is added to preserve the existing, albeit buggy syntax. The
net effect is that the configure test C code generated is the same and still
always fails with a compile error.
While I have not tested this on any BSD-like systems other than OS X, I believe
this means that os.chflags and/or os.lchflags have been missing-in-action from
builds on OSes where they should be supported for the following releases (i.e
since 2009-11-02):
2.6.5
2.6.6
2.7
3.1.2
3.2a2
A side note for OS X: Apple first introduced lchflags() support in OS X 10.5.
Since the python.org OS X installer pythons are traditionally built to an
10.3/10.4 ABI, none of the OS X installers for the above Python releases would
have had os.lchflags anyway (only os.chflags), except for the new 2.7
32-bit/64-bit installer if the 2.7 test weren't otherwise broken.
The solution is to fix the buggy configure.in macros along the lines suggested
by Nick. I have created and tested three new patches to do this:
issue8746-py3k.patchfor py3k (3.2a2+)
issue8746-27.patch for release-27-maint (2.7+)
issue8746-31.patch for release-31-maint (3.1.2+)
A variant of the 3.1 patch should apply to release-26-maint (2.6.6+) however
2.6 is now in security-fix-only mode.
In each case, the patch only modifies configure.in. It is necessary to run
autoreconf after applying and before checkin. A simple test of the fix is to
do ./configure before and after:
$ rm -f config.log config.status
$ ./configure
$ grep expected identifier or '(' before config.log
conftest.c:191: error: expected identifier or '(' before '[' token
conftest.c:200: error: expected identifier or '(' before ']' token
conftest.c:191: error: expected identifier or '(' before '[' token
conftest.c:200: error: expected identifier or '(' before ']' token
$ patch issue8746-[...].patch
$ autoreconf
$ rm -f config.log config.status
$ ./configure
$ grep expected identifier or '(' before config.log
$
Note that I have not attempted any cross-compiling testing either with or
without the patches.

Garrett Cooper yaneg...@gmail.com added the comment:
That definitely fixes detection for FreeBSD CURRENT with 2.7 and py3k for me.
I'm looking into providing some unit-tests, but the problem is that whether or
not chflags functions on the underlying filesystem is problematic. For
instance, it won't function on msdosfs (Linux calls it vfat), it won't function
on ext[23] (AFAIK), and it didn't function on ZFS (until recently? I'm not sure
whether or not the latest patches for ZFS enhance the filesystem to support
this functionality). So unfortunately adding tests for this feature (while
nice) would potentially be error prone.
Something I tried was:
UF_IMMUTABLE = 2
import tempfile
f = tempfile.mkstemp()[1]
os.getuid()
1000
os.chflags('/tmp', UF_IMMUTABLE)
Traceback (most recent call last):
File stdin, line 1, in module
OSError: [Errno 1] Operation not permitted: '/tmp'
os.chflags(f, UF_IMMUTABLE)
fd = open(f, 'w')
Traceback (most recent call last):
File stdin, line 1, in module
IOError: [Errno 1] Operation not permitted: '/tmp/tmpi_hwY7'
fd = open(f, 'r')
fd = open(f, 'r')
fd.read()
''
os.chflags(f, 0)
fd = open(f, 'w')
fd.write('foo')
fd.close()
fd = open(f, 'r')
fd.read()
'foo'
fd.close()
Also, the flags are missing that are described in the manpage. I'll provide a
patch for those.
Otherwise, it looks like everything's functioning as expected for basic
end-to-end tests with chflags(2).
Thanks!
