(cherry picked from commit b748e3b258)
 2017-12-12 20:29:05 +02:00
Serhiy Storchaka f08b2be441 [3.6] bpo-30978: str.format_map() now passes key lookup exceptions through. (GH-2790) (#2992) 
Previously any exception was replaced with a KeyError exception.

Serhiy Storchaka 523a243840 [3.6] bpo-30605: Fix compiling binary regexs with BytesWarnings enabled. (GH-2016) (#2214) 
Running our unit tests with `-bb` enabled triggered this failure..
(cherry picked from commit 171b9a354e)

Serhiy Storchaka 73fb45df04 [3.6] bpo-30375: Correct the stacklevel of regex compiling warnings. (GH-1595) (#1604) 
Warnings emitted when compile a regular expression now always point
to the line in the user code.  Previously they could point into inners
of the re module if emitted from inside of groups or conditionals..
(cherry picked from commit c7ac7280c3)

Serhiy Storchaka 418d60a525 [3.6] bpo-30298: Weaken the condition of deprecation warnings for inline modifiers. (GH-1490) (#1525) 
Now allowed several subsequential inline modifiers at the start of the
pattern (e.g. '(?i)(?s)...').  In verbose mode whitespaces and comments
now are allowed before and between inline modifiers (e.g.
'(?x) (?i) (?s)...')..
(cherry picked from commit 305ccbe27e)

Benjamin Peterson 6a4b04cd33 Revert "bpo-29571: Use correct locale encoding in test_re (#149)" (#554) (#555)

Nick Coghlan 0683d6889b [3.6] bpo-29571: Use correct locale encoding in test_re (#149) (#153) 
``local.getlocale(locale.LC_CTYPE)`` and
``locale.getpreferredencoding(False)`` may give different answers
in some cases (such as the ``en_IN`` locale).

``re.LOCALE`` uses the latter, so update the test case to match.

Victor Stinner bcf4dccfa7 Issue #28727: Optimize pattern_richcompare() for a==a 
A pattern is equal to itself.
 2016-11-22 15:30:38 +01:00
Victor Stinner b44fb128ae Implement rich comparison for _sre.SRE_Pattern 
Issue #28727: Regular expression patterns, _sre.SRE_Pattern objects created by
re.compile(), become comparable (only x==y and x!=y operators). This change
should fix the issue #18383: don't duplicate warning filters when the warnings
module is reloaded (thing usually only done in unit tests).

Serhiy Storchaka 662cef66d7 Issue #25953: re.sub() now raises an error for invalid numerical group 
reference in replacement template even if the pattern is not found in
the string.  Error message for invalid group reference now includes the
group index and the position of the reference.
Based on patch by SilentGhost.
