[issue14773] fwalk breaks on dangling symlinks
Hynek Schlawack h...@ox.cx added the comment: So I've changed the patch to ignore everything missing except for dangling links (which throw unfortunately the same exception). Just to stress it once more: a fwalk that _ignores_ dangling symlinks is worthless for rmtree. And wasn't rmtree the initial reason to implement fwalk in the first place? ;) -- Added file: http://bugs.python.org/file25556/fwalk-ignore-missing-files.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14773 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue14744] Use _PyUnicodeWriter API in str.format() internals
STINNER Victor victor.stin...@gmail.com added the comment:
To prepare a deeper change, here is a first simple patch. Change how the size
of the _PyUnicodeWriter buffer is handled:
* overallocate by 100% (instead of 25%) and allocate at least 100 characters
* don't overallocate when possible
It is possible to not overallocate when the format string has no prefix nor
suffix and when there is only one argument. For example, %s % abc does
directly allocate the exact buffer size and so don't need to call realloc() at
the end.
The patch does also micro-optimize (cleanup?) _PyUnicodeWriter_Finish.
When it's possible to not overallocate, the speed up is around 10% for short
strings (I suppose that it's much better to longer strings).
