[issue9981] let make_buildinfo use a temporary directory on windows
New submission from Kristján Valur Jónsson krist...@ccpgames.com: make_buildinfo currently creates temporary files getbuildinfo2.c and getbuildinfo.o in the current build directory. This update allows the caller to specify a temp directory to put those files in. The PCBuild pythoncore.vcproj now makes use of this, to put the.c and .o files in the current temporary directory $(IntDir). This makes it possible to compile multiple project configurations in parallel, with tools such as incredibuild, without fearing that each will trample the other's getbuildinfo files. Also removed an unnecessary 64 bit config for make_buildinfo. -- components: Interpreter Core messages: 117576 nosy: krisvale priority: normal severity: normal status: open title: let make_buildinfo use a temporary directory on windows type: compile error versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9981 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue9979] Create PyUnicode_AsWideCharString() function

It is not easy to fix this problem because the callers of PyUnicode_AsWideChar() suppose that the output (wide character) string has the same length (in character) than the input (PyUnicode) string (suppose that sizeof(wchar_t) == sizeof(Py_UNICODE)). And PyUnicode_AsWideChar() doesn't write nul character at the end if the output string is truncated. To prepare this change, a new PyUnicode_AsWideCharString() function would help because it does compute the size of the output buffer (whereas PyUnicode_AsWideChar() requires the output buffer in an argument).

The conversion code *is* pretty much identical, but 3.2 now uses a different algorithm for str (it's equal to repr now). So I'd expect that you'll see the issue in 3.2 too if you try something like '%.12g' % 38210.0 Kiriakos, can you explain a bit more what the difference is between the 'remote engine' and the 'stand along interpreter'?

[issue1669539] Change (fix!) os.path.isabs() semantics on Win32
Ulrich Eckhardt eckha...@satorlaser.com added the comment: I just stumbled across the issue with isabs(). I'd also say that Mark Hammond already provided the typical use case for this, i.e. that you allow relative paths for convenience when storing them or putting them on the commandline, but for actual use you first convert them so that their meaning doesn't change under your feet, e.g. because they depend on volatile things like the current working directory or drive. If you assume that is the intention or typical use case, then calling isabs() to determine if the path is stable doesn't work. Of course, the wording of the documentation then needs to change, too, as it explicitly says after chopping off a potential drive letter. Concerning the behaviour of path.join() and support for \\server\share paths, I'm not sure, but I think that these are issues that can be discussed/changed separately. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1669539 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I am afraid I do not have a minimal code to reproduce this, since the error only occurs with the python.dll embedded to PyScripter. To reproduce with PyScripter you need to a) Download and install the latest version of PyScripter from pyscripter.googlecode.com b) Set the python engine to the internal (embedded python) using the menu (Run, Python Engine, Internal) c) Execute in the interpreter window str(38210.0) etc. The puzzling thing is that the same Python.dll when used by python.exe and not PyScripter produces correct results.

I mildly disagree, IMHO pprint should be able to make a decent job of all the built in types otherwise it loses its value as a debugging tool.

This would surely be an excellent use of the abstract base classes defined in the collections module for pprint to make a best guess as to how to print types it doesn't understand directly?

[issue9630] Reencode filenames when setting the filesystem encoding

As I wrote in my first message (msg114191), there are two other good reasons to keep the current code but redecode filenames: * Encoding aliases: locale encoding is not always written as the official Python encoding name. Eg. utf8 vs UTF-8, iso8859-1 vs latin_1, etc. We have to be able to load Lib/encodings/aliases.py to to get the Python codec. * Codecs implemented in Python: only ascii, latin1, utf8 and mbcs codecs are builtin. All other encodings are implemented in Python. If your filesystem encoding is ShiftJIS, you have to load Lib/encodings/shift_jis.py to load the codec. For these two reasons, we have to import Python modules before being able to set the filesystem encoding. So we have to redecode filenames after setting the filesystem encodings. the redecoding of the filenames is fragile We can setup a buildbot installed in a non-ascii path. Antoine had such buildbot, which already helped to find many bugs related to non-ascii paths. -- We can choose to only support ascii, latin1, utf8 and mbcs for the filesystem encoding, but users will complain that we break compatibility with old systems. Python3 already breaks the language, I don't think that it is a good idea to choose to become incompatible with old systems just to simplify (too much) the code. -- Another solution would be to unload all modules, clear all caches, delete all code objects, etc. after setting the filesystem encoding.

No, that's not needed ! Please see my earlier message: you can still do all this at a later time during startup and double-check that the encoding is indeed valid. The main point is that you don't need to apply all those checks before setting the file system encoding in the interpreter. Early on you just assume that the env vars are setup correctly and head on into starting up the interpreter. If the decoding fails during startup due to a wrong encoding of file or path names, the interpreter will signal this. If you have a case where everything imports fine, you can then still double check at the time the file system encoding is set now to e.g. detect cases where the encoding was set to ascii, but in reality the interpreter was just lucky and the file system encoding should be utf-8. -- title: Redecode filenames when setting the filesystem encoding - Reencode filenames when setting the filesystem encoding ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9630 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue9630] Reencode filenames when setting the filesystem encoding

So the only reason why you have to go through all those hoops is to * allow the complete set of Python supported encoding names for the PYTHONFSENCODING * make sure that the Py_FilesystemDefaultEncoding is set to the actual name of the codec as used by the system Not only. As I wrote in my first message (msg114191), there are two other good reasons to keep the current code but redecode filenames: * Encoding aliases: locale encoding is not always written as the official Python encoding name. Eg. utf8 vs UTF-8, iso8859-1 vs latin_1, etc. We have to be able to load Lib/encodings/aliases.py to to get the Python codec. * Codecs implemented in Python: only ascii, latin1, utf8 and mbcs codecs are builtin. All other encodings are implemented in Python. If your filesystem encoding is ShiftJIS, you have to load Lib/encodings/shift_jis.py to load the codec. For these two reasons, we have to import Python modules before being able to set the filesystem encoding. So we have to redecode filenames after setting the filesystem encodings. No, that's not needed ! Please see my earlier message: you can still do all this at a later time during startup and double-check that the encoding is indeed valid. I don't understand how. Eg. if you set Py_FileSystemDefaultEncoding to cp1252 before loading the first module, import a module will have to load the codec. Load the codec require to import a module. But how can you open cp1252 module since you are unable to encode paths to the filesystem encoding (because the cp1252 codec is not available yet)? If the decoding fails during startup due to a wrong encoding of file or path names, ... It is not not problem described in my previous message. How do you load non- builtin codecs? Can you write a patch implementing your ideas? I tried to write such patch (set Py_FileSystemDefaultEncoding before loading the first module), but it doesn't work for different reasons (all described in this issue).

[issue9985] difflib.SequenceMatcher has slightly buggy and undocumented caching behavior
New submission from Marien Zwart m_zw...@123mail.org: SequenceMatcher caches the result of get_matching_blocks and get_opcodes. There are some problems with this: What get_matching_blocks caches is a list of tuples. The first call does not return that list: it returns map(Match._make, self.matching_blocks) (converting the tuples to namedtuples). Subsequent calls just return self.matching_blocks directly. Especially in python 3 and up this is weird, since the first call returns a map object while later calls return a list. This caching behavior is not documented, so calling code may mutate the returned list. One example of calling code is difflib itself: get_grouped_opcodes mutates the result of get_opcodes (a cached list). I am not sure if the right fix is to have get_grouped_opcodes copy before it mutates or to have get_opcodes return a copy. Snippet demonstrating both bugs: matcher = difflib.SequenceMatcher(a='bc', b='dc') print(list(matcher.get_matching_blocks())) # This should print the same thing, but it does not: print(list(matcher.get_matching_blocks())) print(matcher.get_opcodes()) print(list(matcher.get_grouped_opcodes())) # This should print the same thing as the previous get_opcodes() # list, but it does not: print(matcher.get_opcodes()) -- components: Library (Lib) messages: 117612 nosy: marienz priority: normal severity: normal status: open title: difflib.SequenceMatcher has slightly buggy and undocumented caching behavior type: behavior versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9985 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

david db.pub.m...@gmail.com added the comment: Welcome to 2010. SSL shouldn't be difficult to use anymore or support in python applications. But yet, until the changes in http://bugs.python.org/issue9983 was fixed python devs were using modules without any warning of the security implications. pycurl works ... but a *LOT* of coders are not using pycurl. Today they are still getting it wrong and are still vulnerable to mitm attacks against https on the client side. I have an example in fairly large open source project: bzr -- (by default due to a dependency failure ... on not depending on pycurl). https://bugs.edge.launchpad.net/ubuntu/+source/checkbox/+bug/625076 Less large: libcloud http://github.com/apache/libcloud/issues/issue/2 linode-python http://github.com/tjfontaine/linode-python/issues/issue/1 I would *very* much like to see these methods fixed by default. You can talk about how the ssl protocol is not secure because of ca's handling certificates poorly, but until you *actually* perform proper validation you cannot say these things imho. I can keep on looking at python projects and reporting these issues but it is really easy, just look at anything that says and is important that mitm isn't possible against it - then check the deps. in ubuntu /debian and pick the ones that don't use pycurl, check they don't validate the common name etc. and then you have a bunch of mitm'able apps probably ;) -- nosy: +db ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1589 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5672] Implement a way to change the python process name
Ludvig Ericson lud...@lericson.se added the comment: I use the setproctitle module extensively. It has worked flawlessly. What would be needed for this to get accepted? I realize one shouldn't stress such a decision, but still I feel this is something the standard library should be able to do. My justification for inclusion into the standard library is that one has to make a workaround on systems where setproctitle ISN'T installed (I don't feel such a small component should be a requirement for production use.) Everywhere I use setproctitle, I have to go: try: from setproctitle import setproctitle except ImportError: setproctitle = lambda t: None Which is not only rather lengthy, but also IMO entirely unnecessary. As I noted, setting the process title is mostly for convenience and aesthetics, and therefore it's hard to justify the dependency. For that reason I think standard library inclusion is more relevant than otherwise. So, are there any other reasons to wait with this other than the need of a PEP and proposing that to python-dev or whatever forum is best suited? -- nosy: +lericson ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5672 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

So the only reason why you have to go through all those hoops is to * allow the complete set of Python supported encoding names for the PYTHONFSENCODING * make sure that the Py_FilesystemDefaultEncoding is set to the actual name of the codec as used by the system Not only. As I wrote in my first message (msg114191), there are two other good reasons to keep the current code but redecode filenames: * Encoding aliases: locale encoding is not always written as the official Python encoding name. Eg. utf8 vs UTF-8, iso8859-1 vs latin_1, etc. We have to be able to load Lib/encodings/aliases.py to to get the Python codec. * Codecs implemented in Python: only ascii, latin1, utf8 and mbcs codecs are builtin. All other encodings are implemented in Python. If your filesystem encoding is ShiftJIS, you have to load Lib/encodings/shift_jis.py to load the codec. For these two reasons, we have to import Python modules before being able to set the filesystem encoding. So we have to redecode filenames after setting the filesystem encodings. No, that's not needed ! Please see my earlier message: you can still do all this at a later time during startup and double-check that the encoding is indeed valid. I don't understand how. Eg. if you set Py_FileSystemDefaultEncoding to cp1252 before loading the first module, import a module will have to load the codec. Load the codec require to import a module. But how can you open cp1252 module since you are unable to encode paths to the filesystem encoding (because the cp1252 codec is not available yet)? Ah, sorry, I forgot about that important circular reference :-) You're right: there's no way to guarantee that file and path decoding will work without first setting the file system encoding to one of the builin codec names (latin-1 would be a good choice). The other option would be to import everything using relative paths (since Python itself only uses ASCII path names to the modules), until the codec is loaded and then add the absolute paths to these relative ones, once the codec has been loaded successfully. A third option is the one you mentioned earlier on: we simply don't allow Python to be installed on paths that are not decodable using one of the builtin codecs. If the decoding fails during startup due to a wrong encoding of file or path names, ... It is not not problem described in my previous message. How do you load non- builtin codecs? Can you write a patch implementing your ideas? I tried to write such patch (set Py_FileSystemDefaultEncoding before loading the first module), but it doesn't work for different reasons (all described in this issue). Maybe I misunderstood your proposition. No, I wasn't thinking of the situation where you want to use a codec that requires a Python module. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9630 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1589] New SSL module doesn't seem to verify hostname against commonName in certificate
Zooko O'Whielacronx zo...@zooko.com added the comment: This appears to be a concern for some people. Maybe the builtin ssl module should be deprecated if there isn't a lot of manpower to maintain it and instead the well-maintained pyOpenSSL package should become the recommended tool? Here is a letter that I just received, in my role as a developer of Tahoe-LAFS, from a concerned coder who doesn't know much about Python: An FYI on Python. I'm not sure how businesses handle this (I've always worked in Windows shops), but I imagine some might consider pulling Python until it is properly secured. Pulling Python might affect Tahoe, which I would like to see do well. Here is my reply to him: Thanks for the note warning me about this issue! I appreciate it. The Tahoe-LAFS project doesn't use the builtin ssl module that comes with the Python Standard Library and instead uses the separate pyOpenSSL package (and uses the separate Twisted package for HTTP and other networking protocols). Therefore this isn't an issue for Tahoe-LAFS. I agree that it is potentially a marketing issue in that people might mistakenly think that Tahoe-LAFS is vulnerable or might, as you suggest, blacklist Python as such and thus hit Tahoe-LAFS as collateral damage. There's not much I can do about that from the perspective of a Tahoe-LAFS developer. From the perspective of contributor to Python, I'm also not sure what to do, except perhaps to complain. :-) I guess I'll try to stir the waters a bit by suggesting that Python should deprecate the builtin ssl module and recommend the pyOpenSSL package instead. -- nosy: +zooko ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1589 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue9990] PyMemoryView_FromObject alters the Py_buffer after calling PyObject_GetBuffer when ndim 1
New submission from Lenard Lindstrom le...@telus.net: If an exporter returns a Py_buffer with ndim 1, PyMemoryView_FromObject changes the shape and strides pointer fields to point to a local Py_buffer array field.

[issue9959] int(math.log(4,2)) == 1 instead of 2
Mark Dickinson dicki...@gmail.com added the comment: Applied further tweaks in r85120: for an integer n, log(n) is now computed as log(float(n)), provided only that n is small enough to be converted to a float without overflow. This puts log on a more equal footing with all the other math module functions, and satisfies the (reasonable, IMO) expectation that log(n) == log(float(n)) for small integers n. As a nice side-effect, this change guarantees that on a machine where log10 has reasonable accuracy (e.g., accurate to within 0.9 ulps or so), log10(10**n)==n for any nonnegative integer n such that 10**n is within the range of a double. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9959 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Stefan Krah stefan-use...@bytereef.org added the comment:
I can reproduce this using the internal (embedded python) of PyScripter
(nice work BTW!).
I can't reproduce it under any other circumstances. The test case
from #9215 runs fine in VS, and also this produces the correct output:
#include Python.h
int
main(int argc, char *argv[])
{
Py_Initialize();
PyRun_SimpleString(print str(38210.0));
Py_Finalize();
return 0;
}
I ran all tests with the x86 release of 2.7.
