Add new API linux_distribution() which supports reading the full distribution name and also knows how to parse LSB-style release files. Redirect the old dist() API to the new API (using the short distribution name taken from the release file filename). Add branch and revision to _sys_version(). Add work-around for Cygwin to libc_ver().

Pretty-print the Python version used for running PyBench. Let the user know when calibration has finished. [ 1563844 ] pybench support for IronPython: Simplify Unicode version detection.

This should probably all be merged into the 2.5 maintenance branch: - self->statement was not checked while fetching data, which could lead to crashes if you used the pysqlite API in unusual ways. Closing the cursor and continuing to fetch data was enough. - Converters are stored in a converters dictionary. The converter name is uppercased first. The old upper-casing algorithm was wrong and was replaced by a simple call to the Python string's upper() method instead. -Applied patch by Glyph Lefkowitz that fixes the problem with subsequent SQLITE_SCHEMA errors. - Improvement to the row type: rows can now be iterated over and have a keys() method. This improves compatibility with both tuple and dict a lot. - A bugfix for the subsecond resolution in timestamps. - Corrected the way the flags PARSE_DECLTYPES and PARSE_COLNAMES are checked for. Now they work as documented. - gcc on Linux sucks. It exports all symbols by default in shared libraries, so if symbols are not unique it can lead to problems with symbol lookup. pysqlite used to crash under Apache when mod_cache was enabled because both modules had the symbol cache_init. I fixed this by applying the prefix pysqlite_ almost everywhere. Sigh. ........ r53423 | guido.van.rossum | 2007-01-14 04:46:33 +0100 (Sun, 14 Jan 2007) | 2 lines Remove a dependency of this test on $COLUMNS. ........ r53425 | ka-ping.yee | 2007-01-14 05:25:15 +0100 (Sun, 14 Jan 2007) | 3 lines Handle old-style instances more gracefully (display documentation on the relevant class instead of documentation on <type 'instance'>). ........ r53440 | vinay.sajip | 2007-01-14 22:49:59 +0100 (Sun, 14 Jan 2007) | 1 line Added WatchedFileHandler (based on SF patch #1598415) ........ r53441 | vinay.sajip | 2007-01-14 22:50:50 +0100 (Sun, 14 Jan 2007) | 1 line Added documentation for WatchedFileHandler (based on SF patch #1598415) ........ r53442 | guido.van.rossum | 2007-01-15 01:02:35 +0100 (Mon, 15 Jan 2007) | 2 lines Doc patch matching r53434 (htonl etc. now always take/return positive ints). ........
