| | | | | | | | | | | | | (GH-91702) (GH-91831) (GH-91836) In expression (?(group)...) an appropriate re.error is now raised if the group number refers to not defined group. Previously it raised RuntimeError: invalid SRE code.

* bpo-39394: Improve warning message in the re module (GH-31988)Miss Islington (bot)2022-03-191-3/+6
| | | | | | | A warning about inline flags not at the start of the regular expression now contains the position of the flag. (cherry picked from commit 4142961b9f5ad3bf93976a6a7162f8049e354018) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

* bpo-36929: Modify io/re tests to allow for missing mod name (#13392)Max Bernstein2019-05-211-12/+16
| | | | | | | | | | | | | | | | | | * bpo-36929: Modify io/re tests to allow for missing mod name For a vanishingly small number of internal types, CPython sets the tp_name slot to mod_name.type_name, either in the PyTypeObject or the PyType_Spec. There are a few minor places where this surfaces: * Custom repr functions for those types (some of which ignore the tp_name in favor of using a string literal, such as _io.TextIOWrapper) * Pickling error messages The test suite only tests the former. This commit modifies the test suite to allow Python implementations to omit the module prefix. https://bugs.python.org/issue36929
* bpo-29571: Fix test_re.test_locale_flag() (GH-12099)Victor Stinner2019-02-281-2/+1
| | | | | | | | | Use locale.getpreferredencoding() rather than locale.getlocale() to get the locale encoding. With some locales, locale.getlocale() returns the wrong encoding. For example, on Fedora 29, locale.getlocale() returns ISO-8859-1 encoding for the "en_IN" locale, whereas locale.getpreferredencoding() reports the correct encoding: UTF-8.
* bpo-34294: re module, fix wrong capturing groups in rare cases. (GH-11546)animalize2019-02-181-0/+34
| | | | | | Need to reset capturing groups between two SRE(match) callings in loops, this fixes wrong capturing groups in rare cases. Also add a missing index in re.rst.

* bpo-30605: Fix compiling binary regexs with BytesWarnings enabled. (#2016)Roy Williams2017-06-101-2/+14

* bpo-30375: Correct the stacklevel of regex compiling warnings. (#1595)Serhiy Storchaka2017-05-161-3/+14
| | | | | | 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.
* bpo-30299: Display a bytecode when compile a regex in debug mode. (#1491)Serhiy Storchaka2017-05-141-0/+27
| | | | | `re.compile(..., re.DEBUG)` now displays the compiled bytecode in human readable form.
* bpo-30340: Enhanced regular expressions optimization. (#1542)Serhiy Storchaka2017-05-141-14/+12
| | | | This increased the performance of matching some patterns up to 25 times.
* bpo-30298: Weaken the condition of deprecation warnings for inline ↵Serhiy Storchaka2017-05-101-14/+45

* bpo-30215: Make re.compile() locale agnostic. (#1361)Serhiy Storchaka2017-05-051-0/+32
| | | | | | Compiled regular expression objects with the re.LOCALE flag no longer depend on the locale at compile time. Only the locale at matching time affects the result of matching.

| | | | | | | ``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.
