[issue15564] cgi.FieldStorage should not call read_multi on files
patrick vrijlandt added the comment: I must admit my usage case is a hack, but the summary is: view a page on one computer, process it on another computer; like sending the page to a friend, with friend - self and send - upload. I found one other victim in python (https://groups.google.com/d/topic/web2py/ixeUUWryZh0/discussion) but only an occasional reference to other languages; most posts relate to security issues with mht files. My previous example only served to show that the mime-type is a necessary condition for the problem to occur; you are right that this input would be expected to throw an exception. So I went on and created a complete testcase/example (attached). The PatchedFieldStorage class parses the mht file correctly into parts. However, the names of the parts are in content-location headers inside the mht file and get lost. Also the code is ugly. Trying to better re-use existing code like in ExperimentalFieldStorage was not succesful so far: The MIME-prologue is parsed as one of the parts, and the outerboundary is not respected, losing a dataelement next to the file. The print() calls show that the next line may be valuable (like a header) or not so much (like a boundary), but so far the class has no provision for look-ahead I think. email.message_from_binary_file correctly parses my mht-files; so a completely different approach might be to more rely on that package for parsing MIME encoded data. -- Added file: http://bugs.python.org/file26780/test_cgi4.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15564 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15639] csv.Error description is incorrectly broad
New submission from Xavier Morel: In both Python 2.7 and Python 3.x, csv.Error is documented as: Raised by any of the functions when an error is detected. As far as I can tell from using the module and looking at the code, this is completely incorrect. There is actually a single instance of csv.Error being used: the instantiation of csv.Dialect (which converts TypeError raised from _csv._Dialect() into csv.Error, a comment notes that this is for compatibility with py 2.3). And the only way to hit that code paths seems to be subclassing `Dialect` and putting incorrect values in the various attributes (providing them to `csv.reader` raises a TypeError). I believe the documentation to csv.Error should be changed to: 1. Mark it as effectively deprecated 2. Indicate that the only situation in which it it may be raised is when initializing a subclass of csv.Dialect -- assignee: docs@python components: Documentation messages: 168096 nosy: docs@python, xmorel priority: normal severity: normal status: open title: csv.Error description is incorrectly broad versions: Python 2.7, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15639 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

This is explained by the change in MALLOC memory, before: MALLOC405.9Msee MALLOC ZONE table below MALLOC guard page32K MALLOC metadata 376K Total: about 406 MByte After: MALLOC208.9Msee MALLOC ZONE table below MALLOC freed, no zone 456.0M MALLOC guard page32K MALLOC metadata 392K Total: about 665 MByte. The difference is about 260 MBytes, which is significant but less than the difference according to psutil. But: the psutil difference as calculated by the script is the difference in RSS, not VSIZE (which vmmap shows). If I change the _mem function to use the VSIZE the before and after values are: Memory usage: 2390.4 MB Memory usage: 2846.4 MB Difference: about 456 MByte, which is still higher than the output of vmmap. Note that the same behavior can be seen by a much simpler script: print Large x = list(range(124)) print _mem() del x print _mem() print print Small x = list(range(123)) print _mem() del x print _mem() (where _mem is the same function as in testiterbug.py). The output is: Large Memory usage: 527.3 MB Memory usage: 19.3 MB Small Memory usage: 330.6 MB Memory usage: 147.6 MB With this script is see the same pattern with vmmap: with the small list a large amount of memory is in regions of type (MALLOC freed, no zone). All of this clearly points towards malloc not releasing allocated memory to the system. This is perfectly fine and not a bug in either Python or the system. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15635 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15623] Init time relative imports no longer work from __init__.so modules
Meador Inge added the comment:
I debugged this a bit by comparing the behavior of 3.3 against 3.2. For both
cases I used the following code and debugged it in Python via pdb*:
import importlib
importlib.__import__('my_test_package')
ISTM that the difference in behavior is a result of what loader gets chosen for
the initial `import 'my_test_package'`.
With 3.2 a importlib._bootstrap._SourceFileLoader loader gets created against
'my_test_package/__init__.py'. This works fine because _SourceFileLoader fixes
up sys.modules when it loads.
With 3.3 a _frozen_importlib.ExtensionFileLoader loader gets created against
'my_test_package/__init__.so'. This doesn't work because ExtensionFileLoader
does *not* fixup sys.module when it loads.
I hope that helps some.
* Which was a real pain for 3.3 since you are debugging the frozen importlib.
You get line numbers at least, but it would be really nice if you could tell
pdb a source file to use when you are dealing with bytecode only objects and\or
you could disassemble the bytecode from pdb.

[issue15623] Init time relative imports no longer work from __init__.so modules
Eric Snow added the comment: That's helpful, Meador. With regards to the following, there's more to the story: With 3.3 a _frozen_importlib.ExtensionFileLoader loader gets created against 'my_test_package/__init__.so'. This doesn't work because ExtensionFileLoader does *not* fixup sys.module when it loads. In the example Stefan provided, look at my_test_package/__init__.c:921. You'll find PyInit_my_test_package(). The module creation code from msg168026 comes from that function. There PyImport_AddModule gets called, which adds the module to interp-modules. I haven't had time to run this through gdb to see what's happening sys.modules in this case. In general, I'm not familiar enough with extension modules to know if they are actually responsible for adding themselves to sys.modules. I do see a number of places in Python/import.c and friends that touch sys.modules. If importlib is in charge of adding it, though, I'd think that ExtensionFileLoader.load_module would need the module_for_loader decorator. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15623 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

So it means there's no reliable way to measure the memory consumption of the program. What it means is that memory consumption itself is a bit ill-defined. ps, top and friends will tell you the amount of memory (physical or virtual) currently assigned by the OS to the process. It doesn't tell you whether the memory is actually in use by the program. Note that, in Python 3.3, sys._debugmallocstats() gives you fined-grained information about the object allocator.

[issue15623] Init time relative imports no longer work from __init__.so modules
Brett Cannon added the comment:
So imp.load_dynamic() does add a module to sys.modules (I'm using Python 3.2
here because that's what I have access to, but I verified this yesterday at
home)::
Python 3.2.3 (default, May 3 2012, 15:51:42)
[GCC 4.6.3] on linux2
Type help, copyright, credits or license for more information.
import imp
import sys
'resource' in sys.modules
False
mod = imp.load_dynamic('resource',
'/usr/lib/python3.2/lib-dynload/resource.cpython-32mu.so')
mod
module 'resource' from
'/usr/lib/python3.2/lib-dynload/resource.cpython-32mu.so'
'resource' in sys.modules
True
IOW it is not needed for ExtensionFileLoader to add the module explicitly to
sys.modules.
As for Meador's notice that __init__.py was being imported, I believe Stefan is
saying it should work without that file. So deleting __init__.py and only
having __init__.so in Python 3.2 should work. If not then this has been a false
alarm.

[issue15623] Init time relative imports no longer work from __init__.so modules
Stefan Behnel added the comment:
Interesting. I didn't know that. The .py file is always installed automatically
next to the .so file by distutils.
Here's what strace gives me:
Python 2.7:
stat(my_test_package, {st_mode=S_IFDIR|0775, st_size=4096, ...}) = 0
stat(my_test_package/__init__.py, {st_mode=S_IFREG|0664, st_size=557, ...}) = 0
stat(my_test_package/__init__, 0x7fffdc9dd320) = -1 ENOENT (No such file or
directory)
open(my_test_package/__init__.so, O_RDONLY) = 3
open(my_test_package/__init__.so, O_RDONLY|O_CLOEXEC) = 4
Python 3.2:
stat(my_test_package, {st_mode=S_IFDIR|0775, st_size=4096, ...}) = 0
stat(my_test_package/__init__.py, {st_mode=S_IFREG|0664, st_size=557, ...}) = 0
stat(my_test_package/__init__, 0x7fff9d99d700) = -1 ENOENT (No such file or
directory)
stat(my_test_package/__init__.cpython-32mu.so, {st_mode=S_IFREG|0775,
st_size=82517, ...}) = 0
open(my_test_package/__init__.cpython-32mu.so, O_RDONLY) = 3
open(my_test_package/__init__.cpython-32mu.so, O_RDONLY|O_CLOEXEC) = 4
Python 3.3:
stat(./my_test_package, {st_mode=S_IFDIR|0775, st_size=4096, ...}) = 0
stat(./my_test_package/__init__.cpython-33dm.so, {st_mode=S_IFREG|0775,
st_size=36119, ...}) = 0
open(./my_test_package/__init__.cpython-33dm.so, O_RDONLY|O_CLOEXEC) = 3
That's the difference then.
Ok, I think we'll have to emulate this for older CPython versions as well for
the case that the .py file is not there. So it's likely best to let Cython
register the package in sys.modules at init time, right after calling
AddModule().
Still - can this be implemented in CPython for 3.3? Or 3.4, given that it might
appear like a new feature? There shouldn't be all that much to change.

[issue15623] Init time relative imports no longer work from __init__.so modules
Brett Cannon added the comment: My guess is import.c is noticing the __init__.py, creating the module for the package, and then somehow it cascades into importing __init__.so which essentially does a reload on the module object that is already in sys.modules and thus doesn't cause the parent module check to fail. The problem with that is those semantics suck as that assumes cascading semantics which would cross the finder/loader barrier. So we can't keep the *exact* semantics in Python 3.3. But I do see three possible solutions to fixing this. One is testing if having ExtensionFileLoader insert a practically empty module into sys.modules *before* calling imp.load_dynamic(). This would actually be easy to test by using importlib.util.module_for_loader on ExtensionFileLoader.load_module(). This might be a slight change in semantics (and assumes imp.load_dynamic() will do a reload as appropriate instead of blindly creating a new module), but then if anyone is going to notice it will be Cython so if it works in this case and Cython doesn't fail further it is probably safe. The second option is to tweak the extension module initialization process to make sure the module being initialized is inserted into sys.modules early enough and still cleaned up properly. The question, though, is what is it doing now as the module is not passed in directly into the PyInit function but by PyModule_Create instead and I don't know who handles cleanup of the module if something fails and the PyInit returns NULL. Third is having Cython tweak itself for 3.3 to just directly inject the module object into sys.modules before it does any relative imports.

[issue15640] Document deprecate importlib.abc.Finder
New submission from Brett Cannon: importlib.abc.Finder is no longer the proper level of abstraction for either meta path finders or path entry finders, so direct inheritance should be discouraged by documenting deprecation for the class (actual deprecation will need to be avoided as the constructor gets involved and having that error out if someone sets warnings to errors would be bad). Should probably also document as deprecated importlib.abc.PathEntryFinder.find_module(). Also need to remember to update the inheritance hierarchy now added to the docs with a note next to the class about the deprecation (along with PyLoader and PyPycLoader). -- assignee: brett.cannon components: Documentation messages: 168138 nosy: barry, brett.cannon, eric.snow, ncoghlan priority: normal severity: normal stage: needs patch status: open title: Document deprecate importlib.abc.Finder versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15640 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15592] subprocess.communicate() breaks on no input with universal newlines true
Andrew Svetlov added the comment: I like to accept both str and bytes if universal_newlines is False and raise explicit exception for bytes if universal_newlines is True. Looks like universal_newlines for bytes doesn't make sense, also we prefer to use str everywhere. Bytes should be used if it is really byte-stream or if unicode cannot be passed by some limitations of underlying OS etc. There are couple dark corners: 1. What to do if stdin doesn't have `encoding` attribute? Convert to bytes using filesystemencoding? Raise explicit exception? Adding `encode` parameter for .communicate doesn't looks elegant. 2. How .communicate works on Windows? I see completely different implementation of this method for win32.

[issue11549] Build-out an AST optimizer, moving some functionality out of the peephole optimizer
Terry J. Reedy added the comment: In msg132312 Nick asked where do we stand in regards to backwards compatibility of the AST? The current ast module chapter, second sentence, says The abstract syntax itself might change with each Python release; this module helps to find out programmatically what the current grammar looks like. where 'current grammar' is copied in 30.2.2. Abstract Grammar. I do not know when that was written, but it clearly implies the the grammark, which defines node classes, is x.y version specific.
