[issue15381] Optimize BytesIO to so less reallocations when written, similarly to StringIO
Eli Bendersky eli...@gmail.com added the comment:
I wonder if this is a fair comparison, Serhiy. Strings are unicode underneath,
so they have a large overhead per string (more data to copy around). Increasing
the length of the strings changes the game because due to PEP 393, the overhead
for ASCII-only Unicode strings is constant:
import sys
sys.getsizeof('a')
50
sys.getsizeof(b'a')
34
sys.getsizeof('a' * 1000)
1049
sys.getsizeof(b'a' * 1000)
1033
When re-running your tests with larger chunks, the results are quite
interesting:
$ ./python -m timeit -s import io; d=[b'a'*100,b'bb'*50,b'ccc'*50]*1000
b=io.BytesIO(); w=b.write for x in d: w(x) b.getvalue()
1000 loops, best of 3: 509 usec per loop
$ ./python -m timeit -s import io; d=['a'*100,'bb'*50,'ccc'*50]*1000
s=io.StringIO(); w=s.write for x in d: w(x) s.getvalue()
1000 loops, best of 3: 282 usec per loop
So, it seems to me that BytesIO could use some optimization!

[issue15384] FileFinder.path_hook()() returns None on Windows
New submission from Nick Coghlan ncogh...@gmail.com: As noted in #15314, one of the pkgutil tests was failing on Windows because pkgutil.get_importer() was returning None. On my Fedora system it returns FileFinder(.). I've now tweaked that particular test to use a bogus path string so that None is the expected result on all platforms. However, the cross-platform discrepancy is a little disturbing - I would have expected the operation to either fail or succeed regardless of platform. Since pkgutil.get_importer is now just a wrapper that takes care of checking path_importer_cache and then walking sys.path_hooks, I believe the actual culprit is FileFinder.path_hook()() returning None (I'm currently downloading and installing 3.3b1 on my gaming machine to confirm that) -- components: Library (Lib) messages: 165752 nosy: brett.cannon, georg.brandl, ncoghlan priority: normal severity: normal status: open title: FileFinder.path_hook()() returns None on Windows versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15384 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15379] Charmap decoding of no-BMP characters
Amaury Forgeot d'Arc amaur...@gmail.com added the comment:
In 3.2, narrow build is also broken when the charmap is a string:
codecs.charmap_decode(b'\0', 'strict', '\U0002000B')
returns (' ', 1) with a wide unicode build, but ('\ud840', 1) with a narrow
build.
3.2 could be fixed to allow characters up to sys.maxunicode, though.

[issue15385] Behaviour change in runpy for __file__ attributes between 3.2 and 3.3
New submission from Nick Coghlan ncogh...@gmail.com:
Directory setup: linkdir is a symlink to realdir
$ python3 -c import sys; sys.path.insert(0, 'linkdir'); import runpy;
print(runpy.run_module('foo')['__file__'])
/home/ncoghlan/devel/play/realdir/foo.py
$ ../py3k/python -c import sys; sys.path.insert(0, 'linkdir'); import runpy;
print(runpy.run_module('foo')['__file__'])
/home/ncoghlan/devel/play/linkdir/foo.py
The culprit is pkgutil - the import emulation includes a realpath() call.
Looking at the log, this dates from PJE's consolidation of the various import
emulations back in 2006, with no specific rationale given.
Since this was only in the emulation, and nothing else broke when we took it
out (indeed, it was the cause of test failures in 3.2, when it altered the
__file__ values in ways the test wasn't expecting), I'm just creating and
closing this issue to note that yes, I'm aware this has changed, but no, I
don't consider it a problem, as it just brings pkgutil into line with the
behaviour of normal imports.

[issue15364] sysconfig confused by relative paths
Ronald Oussoren ronaldousso...@mac.com added the comment:
I'd make get_config_var('srcdir') to be None for installed systems, because the
source tree is not available there.
The advantage of making the value None is that this is easy to test for and
would quickly break path manipulation code that tries to construct a path to a
specific file in the source tree.
Making the value to be the name of the directory containing Makefile would
still break code that tries to access files relative to the source tree, but
could that breakage could be harder to track.
BTW. sysconfig really needs a better description of which variables are
supposed to be available, it currently exports every definition in the Makefile
and pyconfig.h, and not all of those definitions are usable outside of
CPython's build process.

[issue15386] Still getting two copies of importlib._bootstrap
Nick Coghlan ncogh...@gmail.com added the comment: Checking with importlib.abc and importlib.util (which turned out not to have the problem) put me on the right path: the problem is the import of imp in importlib.__init__ What appears to be happening is that the interpreter sees the partially initialised importlib package, considers it good enough, and continues on with importing _bootstrap and machinery from source. Control eventually returns to __init__ and it overwrites the source version with the frozen version. Changing the __init__ file to do import _imp instead (the same as what import_init does in the C code) was enough to fix it. No patch yet - the actual fix is trivial, but it needs a test. -- nosy: +georg.brandl priority: normal - release blocker stage: - test needed type: - behavior ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15386 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15388] SAX parse (ExpatParser) leaks file handle when given filename input
New submission from Matt Hillsdon m...@corefiling.com: The following example uses make_parser / parse to read a trivial XML document by filename and then attempts to delete the file. On Win32 I can't unlink the file because the parse does not seem to close the file handle. import os import tempfile from xml.sax import make_parser, ContentHandler (handle, path) = tempfile.mkstemp() os.write(handle, bfoo/) os.close(handle) parser = make_parser() parser.parse(path) # This unlink fails on win32. It succeeds if I comment out the call to parse. os.unlink(path) As I provide a filename rather than a file object, I would expect the parse call to both open and close it. I can't see a way to do the clean-up myself. This issue exists in Python 2.7.3 but I could not reproduce it in 3.2.3. Windows cmd transcript: c:\Users\mthPython2.7.3\python.exe fileleak.py Traceback (most recent call last): File fileleak.py, line 14, in module os.unlink(path) WindowsError: [Error 32] The process cannot access the file because it is being used by another process: 'c:\\d\\tmpvyqg2c' c:\Users\mthPython3.2.3\python.exe fileleak.py c:\Users\mth -- components: XML messages: 165779 nosy: mth priority: normal severity: normal status: open title: SAX parse (ExpatParser) leaks file handle when given filename input type: resource usage versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15388 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

The callback idea seams reasonable and sufficient for your use case. I think that you'd probably want to *not* specify that state change that you want i.e. any state change triggers the function.

[issue15384] pkgutil.get_importer() was returning None on Windows buildbots
David Bolen db3l@gmail.com added the comment:
With a local build on my buildbot of the tip of the default branch,
pkgutil.get_importer('') returns FileFilter('.'). The tests also passed.
However, after checking here and realizing the offending code had been removed
from the test, I put it back in and it still fails.
I think the problem is that sys.path[0] is not '' when testing in the buildbot
environment (though it is when I run the debug interpreter interactively).
Within the buildbot scripts it's a path to the stdlib test zip, so for example
in my test tree it's D:\cygwin\home\db3l\test\build\PCbuild\python33_d.zip.
And if I hand that string to pkgutil.get_importer() I do seem to get None back.

[issue9998] ctypes find_library should search LD_LIBRARY_PATH on linux
Vinay Sajip vinay_sa...@yahoo.co.uk added the comment: What changed since http://bugs.python.org/issue2936? Well for one thing, #2936 was a bug report (behavior) but this is an enhancement request. It seems that if you don't know exactly what a library is called, you can't use find_library to locate it even if it happens to be on LD_LIBRARY_PATH - and if you don't have the name, you can't load it using cdll.LoadLibrary. ISTM LoadLibrary wants the full library name (including extension, on Linux); find_library helps determine that in a cross-platform way (since you can just give it the stem of the library rather than the whole filename). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9998 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue14105] Breakpoints in debug lost if line is inserted; IDLE
Roger Serwy roger.se...@gmail.com added the comment: The ColorDelegator is responsible for providing the coloring for the BREAK tag which is used to mark breakpoints. When recoloring, the BREAK tag may be removed (find self.tag_remove in recolorize_main). This is precisely why the breakpoints disappear. On 2.7, you can use Control-/ to toggle the ColorDelegator. Doing so eliminates the behavior you describe. On 3.x, Control-/ is broken due to two ColorDelegators being loaded. See issue13495. A possible solution would be to separate the BREAK tags from the color delegator since these tags ought to be part of the debugging code only. -- nosy: +serwy versions: +Python 3.2, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14105 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15391] Add bitlength function to the math module
New submission from anon unluckykit...@mailinator.com: Many numeric algorithms require knowing the number of bits an integer has (for instance integer squareroots). For example this simple algorithm using shifts is O(n^2): def bitl(x): x = abs(x) n = 0 while x 0: n = n+1 x = x1 return n A simple O(n) algorithm exists: def bitl(x): if x==0: return 0 return len(bin(abs(x)))-2 It should be possible find the bit-length of an integer in O(1) however. O(n) algorithms with high constants simply don't cut it for many applications. That's why I would propose adding an inbuilt function bitlength(n) to the math module. bitlength(n) would be the integer satisfying bitlength(n) = ceil(log2(abs(n)+1)) Python more than ever with PyPy progressing is becoming a great platform for mathematical computation. This is an important building block for a huge number of algorithms but currently has no elegant or efficient solution in plain Python. -- components: Library (Lib) messages: 165818 nosy: anon priority: normal severity: normal status: open title: Add bitlength function to the math module type: enhancement ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15391 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12510] IDLE: calltips mishandle raw strings and other examples
Terry J. Reedy tjre...@udel.edu added the comment: The original patches were to all 3 versions. The later patches were to both 3.x versions and mostly involved get_argspec and expanding the tests. Get_argspec is somewhat different from get_arg_text, the 2.x function it replaced. The main difference I could see is that the latter attempt to deal with old-style classes (I think) and does not use inspect. I *think* I am done changing get_argspec until I try making use of the new PEP 362 function signature objects, but that can only affect 3.3+. (This would be to improve calltips for builtins). So if you want to backport further changes to 2.7, so it can pass more of the expanded test suite, now is a good time. Since the TC test class in 2.7 is derived from object, there seems to be no test of old style classes, so I don't know if just replacing get_arg_text with get_argspec would break anything that actually works, assuming that get_argspec does work ;-). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12510 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue6493] Can not set value for structure members larger than 32 bits
Meador Inge mead...@gmail.com added the comment: The problem is with the 'BIT_MASK' macro, which is currently defined as the following for Windows: #define BIT_MASK(size) ((1 NUM_BITS(size))-1) The C standard says that any attempt to shift left by exactly the bit width is undefined behavior. For the given test case 'NUM_BITS(size) == 32' and the '1' constant is of type 'int'. Thus the behavior is undefined. For x86 Windows with the MSVC++ compiler this ends up as 'SAL edx, CL' and the Intel manuals say that the shift count is masked by 0x1F. Thus the bit mask ends up as '(1 0) - 1 == 0'. Plug the zero mask into the 'SET' macro and you will see why the reported behavior is being observed. I tested Hirokazu's last patch on Windows 7 64-bit and OS X 10.7; I saw no regression. I will apply the patch shortly. -- assignee: - meador.inge ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6493 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15392] Create a unittest framework for IDLE
New submission from Terry J. Reedy tjre...@udel.edu: Idle needs a unittest framework for module test modules. This means a test directory with at least one test module, a runtest module that successfully runs that test module, any new support functions needed for that test module, and inclusion of test_idle in Lib/test. I am thinking of something like Lib/tkinter/test, but without subdirectories. I presume there should be something like tkinter/test/runtests, but I do not know if it reflects current best practice, nor whether it should be in idlelib or in idlelib/test. One feature of runtests and the tkinter framework is separation of tests that do and do not require a gui. This requires cooperation of writers of each test module. Buildbots can only run tests that do not require a gui and nearly everyone else wants the same. On the other hand, we need automated gui tests too. A complete test of idlelib/runtest requires a test module with both kinds of tests. List/test has test_tk. It runs tests with enable_gui=false unless run directly (and intentionally) as the main module. (Testing test_idle would also require tests in both modes.) It checks that tkinter is available. Should test_idle also check that idle is available? (On Windows, one can install both or neither. I don't know the situation on other systems.) This issue was inspired by #12510 and is interdependent with it. As part of that issue, I would like to convert the expanded test set to run under unittest. #12510 needs a place to put a test_calltips module. On the other hand, this issue needs a test_x module to test runtests and test_idle. tkinter/test/support has functions that can be used in idle tests, in particular, simulate_mouse_click(). I believe a needed addition is simulate_text_entry. That is needed to really finish the calltips tests. Currently, complete testing of tooltips requires non-automated hand tests. Would simulate_mouse_click include selecting menu items, or would that be a separate function? With such a test framework established, we could start adding tests as part of other issues, as is normal practice. (Note: tkinter/test is pretty skeletal, and probably could use expansion, but except for support functions immediately needed for test_calltips, that is another issue.) -- assignee: terry.reedy components: IDLE, Tests messages: 165825 nosy: serwy, terry.reedy priority: normal severity: normal stage: test needed status: open title: Create a unittest framework for IDLE type: enhancement versions: Python 3.2, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
