[issue7173] Cython compiler run crashes CPython 3.1.1 and 3.2
Stefan Behnel sco...@users.sourceforge.net added the comment: I'll add a couple of comments about the relevant parts of the code that appears to trigger the crash. The code runs through the parse tree and applies transformations to it. 1) For node matching, we use a dispatcher (in Visitor.py) that looks up methods for node class names (or the nearest matching class in its MRO hierarchy), e.g. a plain Node type would be handled by a visit_Node method, whereas an ExprNode(Node) type would match visit_ExprNode if it exists and visit_Node otherwise. The handler then recursively calls back into the dispatch code to visit its children. For performance reasons, we sometimes reuse existing methods for this through assignment, e.g. instead of reimplementing the default fallback visit_Node all over the place, we assign an existing superclass method to it as in visit_Node = VisitorTransform.recurse_to_children. This may or may not have an impact on this problem (it shouldn't - normally). So far, all of this appears to work perfectly fine also in Py3. It's the next step that seems to be required to trigger the crash. 2) To specify assertions in our test suite, we use an XPath-like language for node tests (poor man's Schematron, sort-of). The implementation in TreePath.py (based on ElementPath in ElementTree 1.3) makes heavy use of generators to traverse the tree. It is used by the TreeAssertVisitor in TestUtils.py, which is itself a recursive tree visitor (as described above). So the situation is as follows. Cython traverses the parse tree recursively, several times in a pipeline, dispatching to methods that further recurse into the tree. One of the pipeline steps is the tree assertion visitor, which, on matching functions, applies the generator-based path language to the tree, that tries to find nodes by iterating over a chain of generators. At some point in this process, somehow, sys.exc_info gets corrupted, and the doctest/unittest framework crashes the runtime with a segfault when trying to print an exception (raised unexpectedly by the pure test). I hope this makes it clearer a) what happens and b) why it's not easy to cut this down into a simple test case. As the previous comments show, it's already hard enough to reproduce it reliably with a reduced test setup. Please do not hesitate to contact me if you need any further information. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5677] Serious interpreter crash and/or arbitrary memory leak using .read() on writable file
Stefan Krah stefan-use...@bytereef.org added the comment: I wonder if this is technically a bug. The stream is not opened for reading and yet you do an fread. I quickly glanced through the C-Standard and I did not find an _explicit_ paragraph that this is undefined behavior, but personally I'd expect it to be. Regarding the last C example. Also here, you do not open using w+. Now, even if you used w+, by the standard you'd have to do an fflush, fseek, fsetpos or rewind before reading.

[issue7823] multiplying a list of dictionaries
New submission from Andrew Hays m...@andrewhays.net:
[{}]*3 should produce a list of dictionaries that are 3 length long, which it
does. However, one would expect that if you assign something to the keyword
'abc' in the first dicitonary (e.g., x[0]['abc'] = 'def') that the other
dictionaries would remain blank (e.g., x = [{'abc': 'def'}, {}, {}]. However,
it appears that each dictionary is filled (e.g., x = [{'abc':'def'},
{'abc':'def'}, {'abc':'def'}]).
Creating a list of dictionaries like this [{}, {}, {}] or appending a
dictionary to a list like this list.append({}) does NOT produce this same
effect, it produces the desired effect.

[issue7826] support caching for 2to3
New submission from Brian Harring ferri...@gmail.com: Bit like unittest, right now it's rather hard to extend 2to3 for caching support (and other outputs) w/out duplicating the main function. Attached is a patch that allows the refactoring tool class to be passed in- at the very least, this patch is enough to remove some of the nastier monkey patching tricks I had to level to inline caching support into 2to3. Actual caching patch will follow shortly; roughly what it does is track the md5 of the original source and use that as a lookup to the transformed version. That caching support isn't useful to the majority of users, but for developers w/ buildslaves it's a very useful reduction in runtime- for example, for 6 buildslaves I run for pkgcore (a py2k source that we translate upon install to py3k if the target is py3k), if the cache is primed this is a reduction of 20s to 1.8s. Two minutes cpu time across the slaves brought down to ~11s. As said, I understand it's a corner case, so getting the caching into 2to3 directly may not be possible. This initial patch however makes it *way* easier to do inline the caching into 2to3 without having to copy/paste main (or do some heinous monkeypatching). Patch is against svn trunk; doesn't apply cleanly to 3.1/2.6, but that's just a minor modification to make it so. -- components: 2to3 (2.x to 3.0 conversion tool) files: allow_alternate_output_tools.patch keywords: patch messages: 98639 nosy: ferringb severity: normal status: open title: support caching for 2to3 type: feature request versions: Python 3.2 Added file: http://bugs.python.org/file16077/allow_alternate_output_tools.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7826 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7826] support caching for 2to3
Brian Harring ferri...@gmail.com added the comment: Attached is a derivative of http://pkgcore.org/trac/pkgcore/browser/ferringb/snakeoil-dev/snakeoil/caching_2to3.py As you can see in that function, some nastyness is required right now to slip it in w/out duplicating code (hence the first patch). Patch attached here inlines the support directly into a new module lib2to3.caching, and derives on the fly a caching version of the RefactoringTool. The on the fly bit is somewhat fancy I admit, but was done so that anyone using an alternate RefactoringTool can get the same benefits. The sole con to this functionality is that it assumes the transformation will always be the same; in other words, it doesn't account for --fix/--nofix, nor changes in the transformation algorithms that would result in differing output. Personally for my uses this was completely valid- when changing the python version (even a minor upgrade) on my buildslaves I'd wipe the caches to be safe anyways. That said, if there *is* interest in getting caching into stdlib for this, I can poke through the code and incorporate awareness of nofix/fix/python version into the cache key. I skipped doing that however since I didn't think there was a chance in hell of caching going into mainline however ;) Either way, for folks targeting py2k and using buildslaves to validate their code and the translation of said code for py3k, either of these patches really is needed to support caching and stop burning cycles. -- Added file: http://bugs.python.org/file16078/2to3-caching.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7826 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7827] recv_into() argument 1 must be pinned buffer, not bytearray
New submission from Andrew Dalke da...@dalkescientific.com:
In Python 2.6 and Python 2.7a2+, I can't socket.recv_into(a byte array
instance).
I get a TypeError which complains about a pinned buffer. I have only an
inkling of what that means. Since an array.array(b) works there, and since
it works in Python 3.1.1, and since I thought the point of a bytearray was to
make things like recv_into easier, I think this exception is a bug in Python
2.6 and 2.7.
Here's my reproducibles:
Python 2.6.1 (r261:67515, Jul 7 2009, 23:51:51)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type help, copyright, credits or license for more information.
import socket
sock = socket.socket()
sock.connect( (python.org, 80) )
sock.send(bGET / HTTP/1.0\r\n\r\n)
18
buf = bytearray(b * 10)
sock.recv_into(buf)
Traceback (most recent call last):
File stdin, line 1, in module
TypeError: recv_into() argument 1 must be pinned buffer, not bytearray
I expected a bytearray to work there. In fact, I thought the point of
bytearray was to allow this to work.
By comparison, an array of bytes does work:
import array
arr = array.array(b)
arr.extend(map(ord, This is a test))
len(arr)
14
sock.recv_into(arr)
14
arr
array('b', [72, 84, 84, 80, 47, 49, 46, 49, 32, 51, 48, 50, 32, 70])
.join(map(chr, arr))
'HTTP/1.1 302 F'
I don't even know what a pinned buffer means, and searching
python.org isn't helpful.
Using a bytearray in Python 3.1.1 *does* work:
Python 3.1.1 (r311:74480, Jan 31 2010, 23:07:16)
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin

18
buf = bytearray(b * 10)
sock.recv_into(buf)
10
buf
bytearray(b'HTTP/1.1 3')
For reference, here's an example with 2.7a2+ (freshly built out of version
control) showing that it does not work there.

[issue7826] support caching for 2to3
Brian Harring ferri...@gmail.com added the comment: @martin: Yeah... that's probably the better approach, although seperation of processes (in terms of setup.py triggering conversion) has some benefits. The reason I used process seperation and invocation of main was to protect my distutils extensions against having to know the innards of lib2to3- either it could invoke the normal 2to3 or invoke the caching version for the buildslaves. Essentially I wanted the caching version to behave the same as normal 2to3 invocations. Not great I'll admit, but so it goes. I'd still like to see the caching integrated in some form w/in stdlib since it has definite benefits- and folk are more likely to use something from stdlib than go raiding from a backwater pkg like snakeoil. That said, we'll see what folks think ;) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7826 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
