SRE incompatibility
by Fredrik Lundh 30 Jun '00

30 Jun '00

my latest changes fixed a couple of things, but broke one of the old RE tests, namely: re.match('\\x00ffffffffffffff', '\377') != None or in other words, long hexadecimal escapes are cast down to 8-bit characters in RE. in SRE (after the latest change), they're cast down to the size of the engine's internal word size (currently 16 bits). is the old behaviour worth keeping? I'd rather not make the engine dependent on string types; it shouldn't really matter if you're using unicode patterns on 8-bit target strings, or vice versa. </F>

SRE: a minor glitch in re.py
by Fredrik Lundh 30 Jun '00

from the new re.py: > ! # change this to "pre" if your regexps stopped working. don't > ! # forget to send a bug report to <some suitable address> is bugs-py(a)python.org suitable? or should we refer people to http://www.python.org/search/search_bugs.html or should they pester me directly?

"make test" vs. "-tt"
by Skip Montanaro 30 Jun '00

30 Jun '00

Per Fredrik's suggestion, I changed "-tt" to simply "-t". I've not yet done a "cvs update" to grab the tab-corrected versions of whatever files were causing the indigestion. I'm down to a single test failure (test_re) now when running "make test" before .py[co] files have been created. I noticed a couple warnings when test_mmap was running though: ./Lib/sre_compile.py: inconsistent tab/space usage ./Lib/sre_parse.py: inconsistent tab/space usage Could it be that when "-tt" detects a problem it causes a broken .py[co] file to be generated? -- Skip Montanaro, skip(a)mojam.com, http://www.mojam.com/, http://www.musi-cal.com/ On Phil Jackson's ability to manage multiple Lakers superstars, Shaquille O'Neal said: "He's got the rings.

--with-cycle-gc switch
by bwarsaw＠beopen.com 30 Jun '00

30 Jun '00

I don't like --with-cycle-gc as the configure switch, and unfortunately configure is explicitly designed not to complain about bogus switches. I just typed --without-gc and was momentarily surprised that the module was still enabled. I propose to change the switch to --with(out)-gc and to not recognize --with(out)-cycle-gc. The switch hasn't been there long enough to support both. -Barry

Removing modules
by Andrew Kuchling 30 Jun '00

30 Jun '00

For the "deleted modules" section of the 2.0 article, I drew up a list of modules that might be outdated, mostly the SGI-specific ones. Are those modules still useful, and do the libraries they were written for still exist? For your cogitation, here's the list: sgimodule.c, glmodule.c (and hence cgenmodule.c), imgfile.c, svmodule.c, flmodule.c, fmmodule.c, almodule.c, clmodule.c, knee.py. Also, can someone explain why importing a third party extension built for Python 1.5.x is supposed to result in an immediate crash on Windows? I'd like to explain why this happens... --amk

So, Setup.thread.in isn't used just for threads anymore. Perhaps it should be renamed? At the very least, a comment should be added to the top that this file is for configure enabled modules. -Barry Index: Setup.thread.in =================================================================== RCS file: /cvsroot/python/python/dist/src/Modules/Setup.thread.in,v retrieving revision 2.2 retrieving revision 2.3 diff -C2 -r2.2 -r2.3 *** Setup.thread.in 2000/06/29 16:08:28 2.2 --- Setup.thread.in 2000/06/30 05:02:53 2.3 *************** *** 11,12 **** --- 11,15 ---- @USE_THREAD_MODULE@thread threadmodule.c + + # Garbage collection enabled with --with-cycle-gc + @USE_GC_MODULE@gc gcmodule.c
