Steve Holden f845877767 Use minimum calibration time rather than avergae to avoid
the illusion of negative run times. Halt with an error if
run times go below 10 ms, indicating that results will be
unreliable.

Thomas Heller ada638bf91 For now, I gave up with automatic conversion of reST to Python-latex,
so I'm writing this in latex now.

Tim Peters 02494764cb Explicitly close files. I'm trying to stop the frequent spurious test_tarfile
failures on Windows buildbots, but it's hard to know how since the regrtest
failure output is useless here, and it never fails when a buildbot slave runs
test_tarfile the second time in verbose mode.

Andrew Dalke 525eab3712 Changes to string.split/rsplit on whitespace to preallocate space in the
results list.

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.

Also changed the last rstrip code to append then reverse, rather than
doing insert(0).  The strip() and rstrip() times are now comparable.

Andrew Dalke 5cc6009f0d Test cases for off-by-one errors in string split with multicharacter pattern. 2006-05-26 12:31:00 +00:00
Andrew Dalke 005aee2c39 I like tests.
The new split functions use a preallocated list.  Added tests which exceed
the preallocation size, to exercise list appends/resizes.

Also added more edge case tests.

Ronald Oussoren 736123605c - Remove previous version of the binary distribution script for OSX
- Some small bugfixes for the IDLE.app wrapper
- Tweaks to build-installer to ensure that python gets build in the right way,
  including sqlite3.
- Updated readme files

Martin Blais 2856e5f390 Support for buffer protocol for socket and struct.
* Added socket.recv_buf() and socket.recvfrom_buf() methods, that use the buffer
  protocol (send and sendto already did).

* Added struct.pack_to(), that is the corresponding buffer compatible method to
  unpack_from().

* Fixed minor typos in arraymodule.

Fredrik Lundh 1b94940165 Py_LOCAL shouldn't be used for data; it works for some .NET 2003 compilers,
but Trent's copy thinks that it's an anachronism...

Ronald Oussoren 567a8ffd09 Integrate installing a framework in the 'make install'
target. Until now users had to use 'make frameworkinstall'
to install python when it is configured with '--enable-framework'.
This tends to confuse users that don't hunt for readme files
hidden in platform specific directories :-)

Ronald Oussoren 39be38c965 - Search the sqlite specific search directories
after the normal include directories when looking
  for the version of sqlite to use.
- On OSX:
  * Extract additional include and link directories
    from the CFLAGS and LDFLAGS, if the user has
    bothered to specify them we might as wel use them.
  * Add '-Wl,-search_paths_first' to the extra_link_args
    for readline and sqlite. This makes it possible to
    use a static library to override the system provided
    dynamic library.

Fredrik Lundh b8b3c8e276 needforspeed: added Py_LOCAL macro, based on the LOCAL macro used
for SRE and others.  applied Py_LOCAL to relevant portion of ceval,
which gives a 1-2% speedup on my machine.  ymmv.

Andrew Dalke 984b971341 Added a few more test cases for whitespace split. These strings have leading whitespace. 2006-05-26 11:11:38 +00:00
Fredrik Lundh f2c0dfdb13 needforspeed: use Py_ssize_t for the fastsearch counter and skip
length (thanks, neal!).  and yes, I've verified that this doesn't
slow things down ;-)
2006-05-26 10:27:17 +00:00
Fredrik Lundh 450277fef5 needforspeed: use METH_O for argument handling, which made partition some
~15% faster for the current tests (which is noticable faster than a corre-
sponding find call).  thanks to neal-who-never-sleeps for the tip.
