* mktemp() shouldn't rely on os.path.exists(), which can return False ifGuido van Rossum2003-11-101-1/+23
| | | | | the file is a symlink. Instead, use os.lstat directly, if it exists; fall back on os.stat or the built-in open. Thanks to Iustin Pop.

* Patch #810914: Return absolute path for mkstemp. Fixes #810408.Martin v. Löwis2003-10-121-1/+1
| | | | | This should not be backported to 2.3, as it might break backwards compatibility.
* Windows fix: When PYTHONCASEOK is set, or for any other reason importsTim Peters2003-07-221-3/+9
| | | | | | | | | | are satisfied in a case-insensitive manner, the attempt to import (the non-existent) fcntl gets satisfied by FCNTL.py instead, and the tempfile module defines a Unix-specific _set_cloexec() function in that case. As a result, temp files can't be created then (blows up with an AttributeError trying to reference fcntl.fcntl). This just popped up in the spambayes project, where there is no apparent workaround (which is why I'm pushing this in now).

* Use the dummy_thread module in Queue.py and tempfile.py.Guido van Rossum2002-12-301-6/+3

* Get rid of _once(); inlining it takes less code. :-)Guido van Rossum2002-08-171-36/+41
| | | | | | | Also, don't call gettempdir() in the default expression for the 'dir' argument to various functions; use 'dir=None' for the default and insert 'if dir is None: dir = gettemptir()' in the bodies. That way the work done by gettempdir is postponed until needed.
* tempfile's mkstemp(): Changed last argument fromTim Peters2002-08-141-10/+10

* Patch #595014: Cygwin tempfile patchJason Tishler2002-08-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | Although Cygwin attempts to be as Posix compliant as possible, it has difficulties unlinking open files. This is not surprising given that Cygwin is dependent on Win32 which in turn has this problem itself. The attached tempfile patch acknowledges this Cygwin limitation. Without this patch, Cygwin fails test_tempfile (i.e., test_has_no_name) as follows: $ ./python -E -tt ../Lib/test/regrtest.py -l test_tempfile test_tempfile test test_tempfile failed -- Traceback (most recent call last): File "/home/jt/src/PythonCvs/Lib/test/test_tempfile.py", line 689, in test_has_no_name self.failOnException("rmdir", ei) File "/home/jt/src/PythonCvs/Lib/test/test_tempfile.py", line 33, in failOnException self.fail("%s raised %s: %s" % (what, ei[0], ei[1])) File "/home/jt/src/PythonCvs/Lib/unittest.py", line 260, in fail raise self.failureException, msg AssertionError: rmdir raised exceptions.OSError: [Errno 90] Directory not empty: '/mnt/c/DOCUME~1/jatis/LOCALS~1/Temp/tmpM_z8nj'
* mkstemp(): Repaired error in docstring (the sense of the 'binary' flagTim Peters2002-08-141-2/+2
| | | | was reversed).
* mkstemp(): The optional "binary" argument is clearly intended to be aTim Peters2002-08-131-1/+1

* Check-in of the most essential parts of SF 589982 (tempfile.pyGuido van Rossum2002-08-091-225/+396
| | | | | | | | rewrite, by Zack Weinberg). This replaces most code in tempfile.py (please review!!!) and adds extensive unit tests for it. This will cause some warnings in the test suite; I'll check those in soon, and also the docs.

* New TemporaryFile implementation for Windows: this doesn't need aTim Peters2002-01-301-1/+17
| | | | | | | | | | | TemproraryFileWrapper wrapper anymore, and should be immune from the problem that a temp file inherited by a spawned process caused an attempt to close the temp file in the spawning process to blow up (the unlink in TemporaryFileWrapper.close() blew up with a "Permission denied" error because, despite that the temp file got closed in the spawning process, the spawned process still had it open by virtue of C-level file descriptor inheritance). In context, that bug took days to figure out <wink/sigh>.
* SF bug #509805 tempfile.gettempdir not threadsafeTim Peters2002-01-281-2/+28
| | | | | | | | | | | | | | | This is an ancient race when multiple threads call gettempdir() (or anything relying on it) for the first time. Fixed x-platform via the Big Hammer of rearranging the code to serialize the first calls. Subsequent calls are as fast as before. Note that the Python test suite can't provoke this bug: it requires setting up multiple threads making the very first calls into tempfile, but the test suite uses tempfile several times before getting to test_threadedtempfile. Bugfix candidate.

* Guido found a brand new race in tempfile on Linux, due to Linux changingTim Peters2001-01-131-16/+31
| | | | | | | | | | | | pid across threads (but in that case, it's still the same process, and so still sharing the "template" cache in tempfile.py). Repaired that, and added a new std test. On Linux, someone please run that standalone with more files and/or more threads; e.g., python lib/test/test_threadedtempfile.py -f 1000 -t 10 to run with 10 threads each creating (and deleting) 1000 temp files.
* A variant of SF patch 103028 (Make tempfile.mktemp threadsafe).Tim Peters2001-01-121-12/+45
| | | | | | | Tested on Windows. Should be tested on Linux. Should also be tested on some platform without threads (I simulated that by making the "import thread" fail, but that's not the same as actually doing it!).
* Patch by tg@FreeBSD.org to try /var/tmp first.Guido van Rossum2000-08-291-1/+1
| | | | This helps on 4.4BSD-based systems.
* Security patch for Unix by Chris McDonough.Guido van Rossum2000-04-241-7/+21
| | | | | | This uses the same precautions when trying to find a temporary directory as when the actual tempfile is created (using O_CREAT and O_EXCL). On non-posix platforms, nothing is changed.
* The third and final doc-string sweep by Ka-Ping Yee.Guido van Rossum2000-02-041-8/+6
| | | | | | | | The attached patches update the standard library so that all modules have docstrings beginning with one-line summaries. A new docstring was added to formatter. The docstring for os.py was updated to mention nt, os2, ce in addition to posix, dos, mac.
* In class TemporaryFileWrapper, don't cache attributes of tpye int --Guido van Rossum1999-06-011-1/+2
| | | | | | these happen to be 'closed' and 'softspace', which may change! Noted by Dave Ascher (with slightly different solution).
* Improvement to the previous fix suggested by Thomas Bellman: if theGuido van Rossum1998-10-241-2/+6
| | | | | unlink() or fdopen() fail, close the file descriptor and re-raise the exception.
* The TemporaryFile() function has a security leak -- because theGuido van Rossum1998-10-241-5/+6
| | | | | | | | | | | | | filenames generated are easily predictable, it is possible to trick an unsuspecting program into overwriting another file by creating a symbolic link with the predicted name. Fix this by using the low-level os.open() function with the O_EXCL flag and mode 0700. On non-Unix platforms, presumably there are no symbolic links so the problem doesn't exist. The explicit test for Unix (posix, actually) makes it possible to change the non-Unix logic to work without a try-except clause. The mktemp() file is as unsafe as ever.
