Much-needed merge (using svnmerge.py this time) of trunk changes into p3yk. Inherits test_gzip/test_tarfile failures on 64-bit platforms from the trunk, but I don't want the merge to hang around too long (even though the regular p3yk-contributors are/have been busy with other things.)

Python 2.4 changed ntpath.abspath to do an import inside the function. As a result, due to Python's import lock, anything calling abspath on Windows (directly, or indirectly like tempfile.TemporaryFile) hung when it was called from a thread spawned as a side effect of importing a module. This is a depressingly frequent problem, and deserves a more general fix. I'm settling for a micro-fix here because this specific one accounts for a report of Zope Corp's ZEO hanging on Windows, and it was an odd way to change abspath to begin with (ntpath needs a different implementation depending on whether we're actually running on Windows, and the _obvious_ way to arrange for that is not to bury a possibly-failing import _inside_ the function). Note that if/when other micro-fixes of this kind get made, the new Lib/test/threaded_import_hangers.py is a convenient place to add tests for them. ........ r45634 | phillip.eby | 2006-04-21 23:53:37 +0200 (Fri, 21 Apr 2006) | 2 lines Guido wrote contextlib, not me, but thanks anyway. ;) ........ r45636 | andrew.kuchling | 2006-04-22 03:51:41 +0200 (Sat, 22 Apr 2006) | 1 line Typo fixes ........ r45638 | andrew.kuchling | 2006-04-22 03:58:40 +0200 (Sat, 22 Apr 2006) | 1 line Fix comment typo ........ r45639 | andrew.kuchling | 2006-04-22 04:06:03 +0200 (Sat, 22 Apr 2006) | 8 lines Make copy of test_mailbox.py.

Johnson's revised version of mailbox.py (funded by the 2005 Summer of Code). The revision adds a number of new mailbox classes that support adding and removing messages; these classes also support mailbox locking and default to using email.Message instead of rfc822.Message. The old mailbox classes are largely left alone for backward compatibility. The exception is the Maildir class, which was present in the old module and now inherits from the new classes. The Maildir class's interface is pretty simple, though, so I think it'll be compatible with existing code. (The change to the NEWS file also adds a missing word to a different news item, which unfortunately required rewrapping the line.) ........ r45641 | tim.peters | 2006-04-22 07:52:59 +0200 (Sat, 22 Apr 2006) | 2 lines Whitespace normalization. ........ r45642 | neal.norwitz | 2006-04-22 08:07:46 +0200 (Sat, 22 Apr 2006) | 1 line Add libctypes as a dep ........ r45643 | martin.v.loewis | 2006-04-22 13:15:41 +0200 (Sat, 22 Apr 2006) | 1 line Fix more ssize_t problems. ........ r45644 | martin.v.loewis | 2006-04-22 13:40:03 +0200 (Sat, 22 Apr 2006) | 1 line Fix more ssize_t issues. ........ r45645 | george.yoshida | 2006-04-22 17:10:49 +0200 (Sat, 22 Apr 2006) | 2 lines Typo fixes ........ r45647 | martin.v.loewis | 2006-04-22 17:19:54 +0200 (Sat, 22 Apr 2006) | 1 line Port to Python 2.5.

The aim of this is to avoid ambiguity in relation to the runtime context set up when the block is executed, and the context objects that already exist in various application domains (such as decimal.Context) - contextlib.contextmanager is renamed to contextfactory This best reflects the nature of the function resulting from the use of that decorator - decimal.ContextManager is renamed to WithStatementContext Simple dropping the 'Manager' part wasn't possible due to the fact that decimal.Context already exists and means something different. WithStatementContext is ugly but workable.

In rare cases of strings specifying true values near sys.maxint, and oddball bases (not decimal or a power of 2), int(string, base) could deliver insane answers. This repairs all such problems, and also speeds string->int significantly. On my box, here are % speedups for decimal strings of various lengths: length speedup ------ ------- 1 12.4% 2 15.7% 3 20.6% 4 28.1% 5 33.2% 6 37.5% 7 41.9% 8 46.3% 9 51.2% 10 19.5% 11 19.9% 12 23.9% 13 23.7% 14 23.3% 15 24.9% 16 25.3% 17 28.3% 18 27.9% 19 35.7% Note that the difference between 9 and 10 is the difference between short and long Python ints on a 32-bit box. The patch doesn't actually do anything to speed conversion to long: the speedup is due to detecting "unsigned long" overflow more quickly. This is a bugfix candidate, but it's a non-trivial patch and it would be painful to separate the "bug fix" from the "speed up" parts. ........ r46134 | bob.ippolito | 2006-05-23 20:46:41 +0200 (Tue, 23 May 2006) | 1 line Patch #1493701: performance enhancements for struct module. ........ r46136 | andrew.kuchling | 2006-05-23 21:00:45 +0200 (Tue, 23 May 2006) | 1 line Remove duplicate item ........ r46141 | bob.ippolito | 2006-05-23 21:09:51 +0200 (Tue, 23 May 2006) | 1 line revert #1493701 ........ r46142 | bob.ippolito | 2006-05-23 21:11:34 +0200 (Tue, 23 May 2006) | 1 line patch #1493701: performance enhancements for struct module ........ r46144 | bob.ippolito | 2006-05-23 21:12:41 +0200 (Tue, 23 May 2006) | 1 line patch #1493701: performance enhancements for struct module ........ r46148 | bob.ippolito | 2006-05-23 21:25:52 +0200 (Tue, 23 May 2006) | 1 line fix linking issue, warnings, in struct ........ r46149 | andrew.kuchling | 2006-05-23 21:29:38 +0200 (Tue, 23 May 2006) | 1 line Add two items ........ r46150 | bob.ippolito | 2006-05-23 21:31:23 +0200 (Tue, 23 May 2006) | 1 line forward declaration for PyStructType ........ r46151 | bob.ippolito | 2006-05-23 21:32:25 +0200 (Tue, 23 May 2006) | 1 line fix typo in _struct ........ r46152 | andrew.kuchling | 2006-05-23 21:32:35 +0200 (Tue, 23 May 2006) | 1 line Add item ........ r46153 | tim.peters | 2006-05-23 21:34:37 +0200 (Tue, 23 May 2006) | 3 lines Get the Windows build working again (recover from `struct` module changes). ........ r46155 | fredrik.lundh | 2006-05-23 21:47:35 +0200 (Tue, 23 May 2006) | 3 lines return 0 on misses, not -1. ........ r46156 | tim.peters | 2006-05-23 23:51:35 +0200 (Tue, 23 May 2006) | 4 lines test_struct grew weird behavior under regrtest.py -R, due to a module-level cache.

Conversion from non-power-of-2 bases remains quadratic-time in the number of input digits (it was and remains linear-time for bases 2, 4, 8, 16 and 32). Speedups at various lengths for decimal inputs, comparing 2.4.3 with current trunk.

Originally it allocated 0 items and used the list growth during append. Now it preallocates 12 items so the first few appends don't need list reallocs. ("Here are some words ."*2).split(None, 1) is 7% faster ("Here are some words ."*2).split() is is 15% faster (Your milage may vary, see dealership for details.) File parsing like this for line in f: count += len(line.split()) is also about 15% faster. There is a slowdown of about 3% for large strings because of the additional overhead of checking if the append is to a preallocated region of the list or not. This will be the rare case. It could be improved with special case code but we decided it was not useful enough. There is a cost of 12*sizeof(PyObject *) bytes per list. For the normal case of file parsing this is not a problem because of the lists have a short lifetime. We have not come up with cases where this is a problem in real life. I chose 12 because human text averages about 11 words per line in books, one of my data sets averages 6.2 words with a final peak at 11 words per line, and I work with a tab delimited data set with 8 tabs per line (or 9 words per line). 12 encompasses all of these.

+First some math:  the largest integer that can be expressed in N base-B digits
+is B**N-1.  Consequently, if we have an N-digit input in base B, the worst-
+case number of Python digits needed to hold it is the smallest integer n s.t.
+
+    BASE**n-1 >= B**N-1  [or, adding 1 to both sides]
+    BASE**n >= B**N      [taking logs to base BASE]
+    n >= log(B**N)/log(BASE) = N * log(B)/log(BASE)
+
+The static array log_base_BASE[base] == log(base)/log(BASE) so we can compute
+this quickly.  A Python long with that much space is reserved near the start,
+and the result is computed into it.
+
+The input string is actually treated as being in base base**i (i.e., i digits
+are processed at a time), where two more static arrays hold:
+
+    convwidth_base[base] = the largest integer i such that base**i <= BASE
+    convmultmax_base[base] = base ** convwidth_base[base]
+
+The first of these is the largest i such that i consecutive input digits
+must fit in a single Python digit.  The second is effectively the input
+base we're really using.
+
+Viewing the input as a sequence <c0, c1, ..., c_n-1> of digits in base
+convmultmax_base[base], the result is "simply"
+
+   (((c0*B + c1)*B + c2)*B + c3)*B + ... ))) + c_n-1

+STRINGLIB_EMPTY

+
+STRINGLIB_CHAR* STRINGLIB_STR(PyObject*)
