[issue23189] Set docstrings to empty string when optimizing with -OO.
Jarle Selvåg added the comment: I agree that -OO does what (people have agreed) it's supposed to do. Many packages manipulates the docstring without checking for 'None' (see list below). For many package developers, it seems hard to remember that the docstrings may disappear after optimization. This behavior is not intuitive. At least in cases where the docstring is set to a string value, the expected behavior in my opinion would be to set its value to an empty string during optimization with -OO. Here are some of the packages that run into trouble when the docstrings are set to 'None' by the -OO optimization: algopy astropy lmfit pyamg pyvisa mpl_toolkits sympy statsmodels patsy sklearn -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23189 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23199] libpython27.a in amd64 release is 32-bit
Steve Dower added the comment: Is the libpython27.a file actually a 32-bit version or is it just corrupted? It seems to be considerably smaller than the version in the 32-bit installer, but it is certainly not being generated from the 32-bit version. I didn't write this code originally, and I don't use MinGW, so I'm not entirely familiar with how it should work. Do I need separate 64-bit tools to build the library for the 64-bit DLL or will the 32-bit tools suffice? Are the interfaces stable enough within 64-bit versions of MinGW that shipping the library makes sense, or are people likely to always need to regenerate it anyway? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23199 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23199] libpython27.a in amd64 release is 32-bit
Zach Welch added the comment: The libpython27.a is an actual 32-bit version, as confirmed by running objdump -t on it. It reports the sections' file format as pe-i386 instead of pe-x86-64. I am only using it for building for the 64-bit target, so I cannot confirm its viability for 32-bit builds. To build 64-bit Windows binaries, you need a MinGW-w64 toolchain (which is a completely separate project from the original MinGW project). The target triplet is x86_64-w64-mingw32. I cannot speak to the stability of the MinGW-w64 library interface, but I would expect it to be stable. To wit, I would be shocked if future changes required regeneration of third-party .a files. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23199 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17911] traceback: add a new thin class storing a traceback without storing local variables
Robert Collins added the comment: w.r.t. a new linecache interface, it looks like we need two attributes from f_globals: __name__ and __loader__, so that we can eventually call __loader__.get_source(__name__). One small change (to let me focus on traceback) would be to add another kw argument to the existing calls that take module_globals, called e.g. get_source, which would be a simple callable (source = get_source()). For the deferred linecache situation, we'd then create partial(f_globals.__loader__.get_source, f_globals.__name__) and keep that around until we need the source. We could even abstract that out into a function in linecache to keep the knowledge in one place. Another way to tackle this would be to add a new function to linecache that lazily seeds the cache: it would stash the get_source method and the name against the filename, and when getline[s] is called actually invoke it. I think the second way is a bit nicer myself.

[issue23227] Generator's finally block not run if close() called before first iteration
New submission from Stephen Drake:
If a generator has its close() method called before any items are requested
from it, a finally block in the generator function will not be executed.
I encountered this when wrapping an open file to alter the result of iterating
over it. Using a generator function with a try/finally block seemed like a
simple way of acheiving this. Here's an example that logs each line as it's
read:
def logged_lines(f):
try:
for line in f:
logging.warning(line.strip())
yield line
finally:
logging.warning('closing')
f.close()
If the generator is created and closed immediately, the underlying file-like
object is left open:
f = urlopen('https://docs.python.org/')
lines = logged_lines(f)
lines.close()
f.closed
False
But once the first item is requested from the generator, close() will trigger
cleanup:
lines = logged_lines(f)
next(lines)
WARNING:root:!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN
'!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN\n'
lines.close()
WARNING:root:closing
f.closed
True
Having read the documentation for yield expressions, I don't believe this
behaviour to be non-conformant - but it still seems like a bit of a gotcha to
me. Should this usage be warned against?
