[issue15203] Accepting of os functions of (path, dir_fd) pair as argument
New submission from Serhiy Storchaka storch...@gmail.com: Since many of os functions were polymorphic in its first argument (path or fd), the logical continuation is to add a (path, dir_fd) pair as yet one case of this argument. In any case dir_fd is incopatible with fd. This simplifies the code of certain functions which takes patch and dir_fd and pass them to lower level without changes, or that use same patch and dir_fd in calls of several functions. This freely adds support of dir_fd to many functions, such as os.path.isdir. This solves the problem of naming multiple dir_fd arguments (src_dir_fd/dst_dir_fd looks ugly). This saves a pre-3.3 signature of some functions, which will facilitate the use of decorators and improve compatibility with alternative implementations. -- components: Library (Lib) messages: 164132 nosy: storchaka priority: normal severity: normal status: open title: Accepting of os functions of (path, dir_fd) pair as argument versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15203 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15202] followlinks/follow_symlinks/symlinks flags unification
Larry Hastings la...@hastings.org added the comment: I assert that followlinks and symlinks are both bad names. I dislike followlinks because links is ambiguous; both hard links and soft links are links, but it's only modifying behavior regarding one of them. Also, it's not PEP-8-compliant (which we can forgive because I'm pretty sure it predates PEP 8). symlinks is far worse, because it's so ambiguous--quick, what does symlinks=False mean? Examine symlinks, or follow them? I agree that we can't rename followlinks and symlinks in 3.x. All we can do for now is move forward. At the same time I refused to be shackled by misguided old nomenclature. So, certainly, I don't want to see follow_symlinks changed. True story: the reason I started writing the patch for #14626 was so I could make sure it used the name follow_symlinks. I was dead certain Serhiy would use one of the existing names ;-) If you really really want this to happen, you'll have to get Georg's permission--and the sooner the better. Already I suspect it is too late. If it ships in 3.3 it will absolutely be too late. I suggest another approach: add a redundant follow_symlinks argument to os.walk, os.fwalk, and the shutil functions. Prefer the new name in documentation but document the presence of the old one. Throw an exception if both are specified in an invocation. We could do that in 3.4. -- nosy: +georg.brandl ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15202 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15200] Faster os.walk
Charles-François Natali neolo...@free.fr added the comment: On the other hand, fwalk also uses a lot of file descriptors. Users with processes which were already borderline on max file descriptors might not appreciate upgrading to find their os.walk calls suddenly failing. It doesn't have to. Right now, it uses O(depth of the directory tree) FDs. It can be changed to only require O(1) FDs, see http://bugs.python.org/issue13734. For example, GNU coreutils rm -rf uses *at() syscalls and only requires a constant number of FDs. Can you figure out why fwalk is faster, and apply that advantage to walk *without* consuming so many file descriptors? I didn't run any benchmark or test, but one reason why fwalk() is faster could be simply because it doesn't do as much path resolution - which is a somewhat expensive operation - thanks to the relative FD being passed. I guess your mileage will vary with the FS in use, and the kernel version (there's been a lot of work to speed up path resolution by Nick Piggin during the last years or so). Anyway, I think that such optimization is useless, because this micro-benchmark doesn't make much sense: when you walk a directory tree, it's usually to do something with the files/directories encountered, and as soon as you do something with them - stat(), unlink(), etc - the gain on the walking time will become negligible. -- nosy: +neologix ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15200 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Larry Hastings la...@hastings.org added the comment: It doesn't have to. Right now, it uses O(depth of the directory tree) FDs. It can be changed to only require O(1) FDs But closing and reopening those file descriptors seems like it might slow it down; would it still be a performance win? Also, I'm not a security expert, but would the closing/reopening allow the possibility of timing attacks? If so, that might still be okay for walk which makes no guarantees about safety. (But obviously it would be unacceptable for fwalk.) Anyway, I think that such optimization is useless, because this micro-benchmark doesn't make much sense: when you walk a directory tree, it's usually to do something with the files/directories encountered, and as soon as you do something with them - stat(), unlink(), etc - the gain on the walking time will become negligible. I'm not sure that usually is true here. I suggest that usually people use os.walk to find *particular files* in a directory tree, generally by filename. So most of the time os.walk really is quickly iterating over directory trees doing very little. I think 20% is a respectable gain, and it's hard for me to say no to functions that make Python faster for free. (Well, for the possible cost of a slightly more expensive algorithm.)

[issue15204] Deprecate the 'U' open mode
New submission from Serhiy Storchaka storch...@gmail.com: Since Python 2.3 many open functions supports Universal line mode (PEP 278). Since 3.0 (and 2.6) PEP 3116 suggests better alternative -- io.TextWrapper. Now support for the 'U' mode in the different open functions is heterogeneous. Some functions simply ignore the 'U' mode (but accept it), others perceive it as a synonym for text-mode, others just pass it on lower lever, other attempt to implement it, but the implementation is obtained imperfect and contradictory (as in ZipExtFile). The documentation for built-in open does not advise the use of the 'U' mode. The 'U' mode support cumbersome. I propose to deprecate the 'U' mode. If someone wanted to work with the universal line support, he'll surely need to work with encodings too, and io.TextWrapper provides is better choise. The deprecation plan for the 'U' mode of open functions might be as follow: 3.3. Deprecating the 'U' mode in docs for all opens (building open, io.open, codecs.open, gzip.open, ZipFile.open, etc). Add suggestion about io.TextWrapper. 3.4. Raise a warning on use of the 'U' mode. 3.5. Raise an exception on use of the 'U' mode. 3.6 (or 4.0?). Remove the 'U' mode processing code. As the first stage involves only the changes to the documentation, I hope deprecation can starts in 3.3. -- assignee: docs@python components: Documentation, IO, Library (Lib) messages: 164142 nosy: docs@python, storchaka priority: normal severity: normal status: open title: Deprecate the 'U' open mode type: behavior versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15204 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Certainly it says *something*: http://www.python.org/dev/peps/pep-0008/#function-and-method-arguments But I grant you, it only specifically addresses self, cls, and function argument names that clash with keywords. I therefore suggest that function arguments are most similar to method names and instance variables--after all, they *are* instance variables. And method names and instance variables say Use the function naming rules. And function names should be lowercase, with words separated by underscores as necessary to improve readability. followlinks is comprised of two words but they are not separated by underscores. (We can also reason by process of elimination: function arguments are wholly dissimilar to constants, package/module names, classes, and exception. All the remaining types of identifiers in Python follow the above rule.) It might actually be nice to clarify PEP 8 on this.

[issue15205] distutils dereferences symlinks on Mac OS X but not on Linux
New submission from Ollie Walsh ollie.wa...@gmail.com: Hi, This is related to #12585. Distutils sdist builds a package tree using hardlinks to the source if supported by the OS. This is then tarred/zipped/etc... If the source contains symbolic links to external files: On Linux (and apparently Solaris) they are not dereferenced and the resulting package is broken. On OSX (and apparently all BSD kernels) a hardlink to a symlink will dereference the symlink first and the resulting tgz package is ok. However I would expect issue #8876 to be more likely as the symlink could references a different filesystem which would case hardlinking to fail. In #12585 I assume that zip dereferences the symlinks which masks the issue. distutils2 appears to always copy instead of hardlinking resolving all of these issues. distutils can be monkey patched to do the same: http://article.gmane.org/gmane.comp.python.distutils.devel/2078 -- assignee: eric.araujo components: Distutils messages: 164149 nosy: eric.araujo, ollie.wa...@gmail.com, tarek priority: normal severity: normal status: open title: distutils dereferences symlinks on Mac OS X but not on Linux type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15205 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1677] Ctrl-C will exit out of Python interpreter in Windows
Tim Golden m...@timgolden.me.uk added the comment: OK, I've run out of time to look, but the culprit looks like it's an odd interaction between my_fgets in myreadline.c and the interrupt handler in signal. There's a section of code which is conditional on ERROR_OPERATION_ABORTED being returned from fgets in the CRT. That then tries to play ball with a the interrupt handler having fired already (in a separate thread) by sleeping for one second and checking that the handler was tripped. If it has then the function returns one and stuff happens elsewhere; it it hasn't then the function behaves as if EOF (ie Ctrl-Z) was pressed and Python exits. That's as far as I've got; it looks like a race condition of some sort but I can't see where. I'm not 100% sure that the SIGINT handler is tripping. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1677 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Christian Heimes li...@cheimes.de: The uuid module uses Mersenne Twister from the random module as last fallback. However a MT isn't suitable for cryptographic purposes. The module should first try to use os.urandom() and then perhaps use its own instance of random.Random, similar to uuid_generate_* [1] The problem doesn't apply to most modern platforms as the uuid module uses either libuuid or the Windows API with ctypes. Therefore I consider the real world severity as low. It may not require a backport to Python 2.x.

Brett Cannon br...@python.org added the comment: This all goes back to my original point: I don't want to promote people shipping around bytecode only as it hampers the use of other VMs. Anyway, I'll continue to contemplate this. Any function would have to verify the magic number and flat-out fail otherwise to prevent parsing issues (e.g. Marc's patch works with or without the file size field to stay compatible with PyPycLoader.write_bytecode() implementations that might not set the file size field; a design flaw that I fixed in SourceLoader by taking away the ability to write bytecode). It would also have it return a dict much like path_stats() for easy comparison / verification. But just to be very clear in case someone is hoping, I will NOT support an API to write bytecode as it make compatibility a nightmare and hampers changing the format as necessary. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15031 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15207] mimetypes.read_windows_registry() uses the wrong regkey, creates wrong mappings
New submission from Dave Chambers dlchamb...@aol.com: The current mimetypes.read_windows_registry() enums the values under HKCR\MIME\Database\Content Type However, this is the key for mimetype to extension lookups, NOT for extension to mimetype lookups. As a result, when 1 MIME types are mapped to a particular extension, the last-found entry is used. For example, both image/png and image/x-png map to the .png file extension. Unfortunately, what happens is this code finds image/png, then later finds image/x-png and this steals the .png extension. The solution is to use the correct regkey, which is the HKCR root. This is the correct location for extension-to-mimetype lookups. What we should do is enum the HKCR root, find all subkeys that start with a dot (i.e. file extensions), then inspect those for a 'Content Type' value. The attached ZIP contains: mimetype_flaw_demo.py - this demonstrates the error (due to wrong regkey) and my fix (uses the correct regkey) mimetypes_fixed.py - My suggested fix to the standard mimetypes.py module. -- components: Windows files: mimetype_flaw_demo.zip messages: 164167 nosy: dlchambers priority: normal severity: normal status: open title: mimetypes.read_windows_registry() uses the wrong regkey, creates wrong mappings type: behavior versions: Python 2.7 Added file: http://bugs.python.org/file26180/mimetype_flaw_demo.zip ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15207 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15202] followlinks/follow_symlinks/symlinks flags unification
Serhiy Storchaka storch...@gmail.com added the comment: I dislike followlinks because links is ambiguous; both hard links and soft links are links, but it's only modifying behavior regarding one of them. Technically, in Unix world any file is a hard link. It is impossible to distinguish a hard link from the original, they are completely equal. So I don't think that there will be a ambiguity, what links are implied, especially, if the documentation is clearly says symbolic links. I therefore suggest that function arguments are most similar to method names and instance variables--after all, they *are* instance variables. Technically, they are local variables. followlinks is comprised of two words but they are not separated by underscores. As getgrouplist or sendfile. What about such argument names as filename and newline? If being a consistent in that, then it must be follow_symbolic_links. And source_directory_file_descriptor instead src_dir_fd. It might actually be nice to clarify PEP 8 on this. I agree. I'm glad you think it's an improvement--we can certainly agree on that! Of course.

[issue15207] mimetypes.read_windows_registry() uses the wrong regkey, creates wrong mappings
Dave Chambers dlchamb...@aol.com added the comment: I added a diff file to the bug. Dunno if that's the same as a patch file, or how to create a patchfile if it's not. Do you know if image/x-png and image/png are included in the registry on all windows versions? I think your question is reversed, in the same way that the code was reversed. You're not looking for image/png and/or image/x-png. You're looking for .png in order to retrieve its mimetype (aka Content Type). While nothing is 100% certain on Windows :), I'm quite confident that every copy will have an HKCR\.png regkey, and that regkey will have a Content Type value, and that value's setting will be the appropriate mometype, which I'd expect to be image/png. I was kinda surprised to find this bug as it's so obvious I started chasing it because Chrome kept complaining that pngs were being served as image/x-png (by CherryPy). There are other bugs (eg: 15199, 10551) that my patch should fix. -Dave -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15207 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12605] Enhancements to gdb 7 debugging hooks
Dave Malcolm dmalc...@redhat.com added the comment:
I believe this was due to this line:
return self._gdbframe.name().startswith('pthread_cond_timedwait')
within is_waiting_for_gil(), and your gdb returned None for
self._gdbframe.name() for your build.
I've changed it to:
name = self._gdbframe.name()
if name:
return name.startswith('pthread_cond_timedwait')
in my latest version.
I've also bulletproofed against the --without-threads case by simply
skipping the cases that fail (some tests run into this gdb error:
Cannot find new threads: generic error
unless we add LD_PRELOAD=PATH-TO-libpthread.so.1 as a workaround, but it
seems that trying to add that workaround is more risky (what path?) than
simply skipping the tests under those circumstances.
Tested successfully on a Fedora 15 x86_64 box (gdb-7.3-43.fc15.x86_64)
with these configurations:
* --with-pydebug
* --with-pydebug --enable-shared
* (no flags = optimized)
* --enable-shared (optimized)
* --with-pydebug --without-threads
(Note that because of issue #14774 I have to regenerate
_sysconfigdata.py between each configuration, otherwise it gets confused
about whether or not the build is optimized)

[issue15209] Re-raising exceptions from an expression
New submission from Tyler Crompton gtr...@gmail.com: As you know, a caught exception can be re-raised with a simple `raise` statement. Plain and simple. However, one cannot re-raise an error with this new `from expression` clause. For example: def getch(prompt=''): '''Get and return a character (similar to `input()`).''' print(prompt, end='') try: return windows_module.getch() except NameError: try: fallback_module.getch() except Exception: raise from None Output: File getch.py, line 11 raise from None ^ SyntaxError: invalid syntax A quick look at the documentation about [raise](http://docs.python.org/dev/reference/simple_stmts.html#the-raise-statement) confirms that this is the intended behavior. In my opinion, one should be able to still re-raise from an expression. -- components: Interpreter Core files: getch.py messages: 164184 nosy: Tyler.Crompton priority: normal severity: normal status: open title: Re-raising exceptions from an expression type: enhancement versions: Python 3.3, Python 3.4 Added file: http://bugs.python.org/file26183/getch.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15209 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15202] followlinks/follow_symlinks/symlinks flags unification
Larry Hastings la...@hastings.org added the comment: after all, they *are* instance variables. Technically, they are local variables. Yeah, tbh I was thinking instance of an invocation here. But PEP 8 probably means instance of a class here. Still, there are three classes of naming things in Python: all uppercase (constants), CapCase (class and exception names), and everything else (lowercase with underscores). I suggest that arguments and local variables belong in the latter camp. At no point does PEP 8 suggest naming anything in lowercase without underscores. As getgrouplist or sendfile. What about such argument names as filename and newline? If being a consistent in that, then it must be follow_symbolic_links. And source_directory_file_descriptor instead src_dir_fd. You are muddling the issue--PEP 8 makes no ruling on abbreviations. Personally, I prefer not to use abbreviations where possible. I've found over the years that they are painfully ambiguous--I can never remember what abbreviation I used. (control becomes... ctl? cntl?) MvL also makes a good point that abbreviations are a hinderance to people who speak little or no English. That said, naming things after their POSIX counterparts has to be okay, and abbreviations are occasionally called for when they are widely understood / have a precedent in the library. So with every example you cite I prefer the extant name over any counterproposal you explicitly suggested. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15202 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
