Serhiy Storchaka 955b6760cf [2.7] bpo-30363: Backport warnings in the re module. (#1577)
Running Python with the -3 option now warns about regular expression
syntax that is invalid or has different semantic in Python 3
or will change the behavior in future Python versions.

Skip Montanaro fc070d2731 add %f format to datetime - issue 1158 2008-03-15 16:04:45 +00:00
Brett Cannon f7188cefb3 Make _strptime.TimeRE().pattern() use ``\s+`` for matching whitespace instead
of ``\s*``.  This prevents patterns from "stealing" bits from other patterns in
order to make a match work.

Closes bug #1730389.  Will be backported.

Brett Cannon c69066501b time.strptime's caching of its locale object was being recreated when the
locale changed but not used during the function call it was recreated during.

The test in this checkin is untested (OS X does not have the proper locale
support for me to test), although the fix for the bug this deals with
was tested by the OP (#1290505).  Once the buildbots verify the test at least
doesn't fail it becomes a backport candidate.

Brett Cannon af3d627022 Use the thread lock's context manager instead of a try/finally statement. 2007-01-28 20:58:00 +00:00
Brett Cannon 9875ba4d4e Remove specific mention of my name and email address from modules. Not really
needed and all bug reports should go to the bug tracker, not directly to me.
Plus I am not the only person to have edited these files at this point.
2007-01-25 23:30:39 +00:00
Brett Cannon 07e1db317d Fix time.strptime's %U support. Basically rewrote the algorithm to be more
generic so that one only has to shift certain values based on whether the week
was specified to start on Monday or Sunday.  Cut out a lot of edge case code
compared to the previous version.  Also broke algorithm out into its own
function (that is private to the module).

Fixes bug #1643943 (thanks Biran Nahas for the report).
2007-01-25 20:22:02 +00:00
Brett Cannon 11b3535280 Make the error message for when the time data and format do not match clearer. 2006-09-26 23:38:24 +00:00
Brett Cannon 5d0bf9446b Change time.strptime() to raise ValueError whenever there is an error in the
format string.  Before exceptions generated by the internal code propagated up
to the user and were not helpful.

Closes bug #1340337.
2005-11-02 23:04:26 +00:00
Brett Cannon a783d06f8c Clear out the regex cache when the TimeRE cache is invalidated by a locale
change.

Fixes bug #1290505.

Brett Cannon f1b2ba6aa1 Fix logic error introduced in last commit. Also add a comment to explain what
the code is doing.

Brett Cannon 6e372d1422 fix bug where str.find() was being misused where __contains__ should have been
used.
2005-08-27 19:25:59 +00:00
Brett Cannon 14adbe77b5 Fix bug of implementation of algorithm for calculating the date from year, week
of the year, and day of the week.  Was not taking into consideration properly
the issue of when %U is used for the week of the year but the year starts on
Monday.

Closes bug #1045381 again.
2004-10-28 04:49:21 +00:00
Brett Cannon 8dc25ad6f2 Fix comments. 2004-10-18 01:47:46 +00:00
Brett Cannon 8abcc5d533 Add support for %U and %W to contribute to calculating the date when the year
and day of the week are specified.

Closes bug #1045381.
2004-10-18 01:37:57 +00:00
Brett Cannon ffa5cf9eae Fix bug introduced by the previous patch by changing TimeRE.__seqToRe() to
accept any iterable instead of only a sliceable object.

Brett Cannon f7948c25a2 Convert a listcomp to a gencomp (was already editing code). 2004-10-06 02:23:14 +00:00
Brett Cannon 4f35c71543 Locale data that contains regex metacharacters are now properly escaped.
Closes bug #1039270.

Raymond Hettinger bac788a3cd Replace str.find()!=1 with the more readable "in" operator. 2004-05-04 09:21:43 +00:00
Brett Cannon 8172ac3d15 Deal with possible case of having time.tzname[1] containing UTC or GMT.
Since it is known ahead of time that UTC and GMT always have no DST adjustment
then just set the isdst value to 0 even if tzname[0] == tzname[1] .
Fixes bug #897817 .

Raymond Hettinger a690a9967e * Migrate set() and frozenset() from the sandbox.
* Install the unittests, docs, newsitem, include file, and makefile update.
* Exercise the new functions whereever sets.py was being used.

Includes the docs for libfuncs.tex.  Separate docs for the types are
forthcoming.

Brett Cannon 953c6f508b Make sure parentheses are escaped when used in the format string.
Closes bug #796149 .  Will be backported.

Brett Cannon 5187a3bcdb Fix handling of bad locale setup where time.tzname[0] == time.tzname[1] and
time.daylight is true.  Add an explicit test for this situation.

Fixed some wording in docstrings.
2003-08-11 07:24:05 +00:00
Brett Cannon f5c96fb74d Fix docstring in LocaleTime. 2003-08-08 01:53:05 +00:00
Brett Cannon 474335ce17 Re-introduce caching of TimeRE and compiled regexes with added thread-safety.
Also remove now unnecessary property attributes for thread safety
(no longer have lazy attributes) and code simplicity reasons.

Timezone storage has been reworked to be simpler and more flexible.  All values
in LocaleTime instances are lower-cased.  This is all done to simplify the
module.

The module now assumes nothing beyond the strptime function will be exposed for
general use beyond providing functionality for strptime.
2003-08-05 04:02:49 +00:00
Brett Cannon 2c24d42d32 Fixes bug of having default argument for TimeRE's __init__ that caused the
LocaleTime instance to only be created once and thus not be recreated when
the locale changed.
2003-07-24 20:02:28 +00:00
Brett Cannon 175ddb5b30 Remove caching of TimeRE (and thus LocaleTime) instance. Error was being
caught when executing test_strptime, test_logging, and test_time in that order
when the testing of "%c" occured.  Suspect the cache was not being recreated
(the test passed when test_logging was forced to re-establish the locale).

Raymond Hettinger 4a6302b6fe SF 748201: time.strptime() should display format and date on error
Usability fix.  Makes the error message more helpful.
2003-07-13 01:31:38 +00:00
Brett Cannon cde2200ff2 Fixes bug of timezone value being left as -1 when ``time.tzname[0] ==
time.tzname[1] and not time.daylight`` is true when it should only when
time.daylight is true.  Tests are also fixed.

Closes bug #763047 and its cohort #763052.

Brett Cannon abe8eb0a30 Call time.tzset (if available) just before calculating possible timezones from time.tzname. 2003-05-13 20:28:15 +00:00
Brett Cannon 172d9ef47e Beefed up timezone support. UTC and GMT are now always recognized timezones
with values of 0.  Also now check time.daylight to see if time.tzname[1]
should be used in timezone checking.
2003-05-11 06:23:36 +00:00
Brett Cannon 2b6dfec1cc Raise a ValueError when there is data that was not covered in the format string. Done to match behavior of pre-existing C-based strptime implementations. 2003-04-28 21:30:13 +00:00

Brett Cannon 1e91d8eb03 Make _strptime escape regex syntax in format string to prevent use in internal regex. 2003-04-19 04:00:56 +00:00
Raymond Hettinger 1fdb633530 SF patch #691928: Use datetime in _strptime
Contributed by Brett Cannon.

To prevent code duplication, I patched _strptime to use datetime's date
object to do Julian day, Gregorian, and day of the week calculations.

Patch also includes new regression tests to test results and the
calculation gets triggered.

Very minor comment changes and the contact email are also changed.

Tim Peters 80cebc16aa SF patch 670194: Performance enhancement for _strptime.py.
From Brett Cannon.  Mostly speedups via caching format string ->
compiled regexp.
2003-01-19 04:40:44 +00:00
Tim Peters 08e54270f2 SF patch 670012: Compatibility changes for _strptime.py.
Patch from Brett Cannon:

    First, the 'y' directive now handles [00, 68] as a suffix for the
    21st century while [69, 99] is treated as the suffix for the 20th
    century (this is for Open Group compatibility).

    strptime now returns default values that make it a valid date ...

    the ability to pass in a regex object to use instead of a format
    string (and the inverse ability to have strptime return a regex object)
    has been removed. This is in preparation for a future patch that will
    add some caching internally to get a speed boost.
