Wed Aug 17 00:06:59 1994 Guido van Rossum (guido@voorn.cwi.nl)
Tue Aug 23 00:52:32 1994 Guido van Rossum (guido@voorn.cwi.nl)
* Lib/os.py: do fake "import posix" for freeze.py script
* Modules/Setup.*: removed all except Setup.in (huh? I thought
I'd done that already?!); disable gdbm by default
* Parser/parsetok.c (parsetok): don't call strncpy(str, NULL, 0)
* Modules/makesetup: support C++ files now; these should be given
as file.C or file.cc or file.c++; C files can be given as file.c
(instead of file.o, which is still supported)
* configure.in, */Makefile*.in: OPT can now be specified in the
env at configure time and will then be put in all Makefiles as
default
* Modules/config.c.in: change mac specific things
* Python/import.c: add lost NT-specific code back in
* Parser/tokenizer.c: backup over illegal newline in string
literal (for "completeness" test)
* Include/node.h: make some fields short to save space during
parsing
* Modules/posixmodule.c: some more NT changes
* Doc/libtime.tex: get rid of references to millitime() and
millisleep(); document clock()
Mon Aug 22 10:53:59 1994 Guido van Rossum (guido@voorn.cwi.nl)
* Lib/linecache.py: don't crash on empty filename
* Lib/macpath.py: don't return trailing colon for dirname()
(XXX won't do for volume names -- but otherwise glob(':*:*.py')
loops forever)
* Lib/traceback.py: print SyntaxError correctly
* Lib/stat.py: moved to posixstat.py; added macstat.py which has
the constants for the Mac; and created new stat.py which includes
the right one
* Modules/signalmodule.c: added pause().
* Python/pythonrun.c (print_error): added INCREF/DECREF pair --
the exception returned by a syntax error (when reported) would
contain an object with refcnt zero!
Fri Aug 19 15:35:44 1994 Guido van Rossum (guido@voorn.cwi.nl)
* */Makefile*.in: remove lib*.a before adding to it
* Lib/urllib.py: fix caching bug (by disabling the cache)
* Lib/sgi/flp.py: fix caching bug (always write the whole file to
the cache!)
* Doc/ref6.tex (section{Assignment statements}): added warning
about overlaps in lhs of assignment (e.g. "i, x[i] = 1, 2")
* Python/errors.c (err_clear): clear interpreter stack trace
Wed Aug 17 16:10:07 1994 Guido van Rossum (guido@voorn.cwi.nl)
* Moved patchlevel.h from Python/ to Include/, moved all code from
version.c to config.c and removed version.c, and changed
Modules/Makefile(.pre.in) to add dependencies on $(MYLIBS) for
config.c (so the date in the version is always current). Also
changed the format of PATCHLEVEL: it is now a string containing
the complete version number, e.g. "1.1".
* Grammar/Grammar: Added #diagram:... comments for Kees Blom's
railroad diagram generator
* Doc/libstring.tex (section{Standard Module \sectcode{string}}):
removed references to {ato{f,i,l},index}_error
* Lib/string.py: find/rfind is now the main implementation and
index/rindex is a wrapper that raises index_error (which is now
always ValueError)
* Modules/stropmodule.c: implement find/rfind instead of
index/rindex (raising and catching an exception is much more
expensive than returning and testing -1)
* Lib/os.py: do fake "import posix" for freeze.py script
Tue Aug 16 23:58:30 1994 Guido van Rossum (guido@voorn.cwi.nl)
* Parser/parsetok.c (parsetok): don't call strncpy(str, NULL, 0)
* Doc/libfuncs.tex (section{Built-in Functions}): added docs for
delattr()

Python release 1.0.3
====================
==> This is patch number 3 to Python 1.0, bumping its version string
to 1.0.3. It consists almost entirely of essential bug fixes to
the C sources. See the file Misc/NEWS for a description of what's
new in this patch (as well as what's new in 1.0).
==> Python 1.0 is the first "official" Python release in more than
half a year. It's significantly improved over version 0.9.9, both
at the functionality level and (especially) in portability of the
source -- you should now be able to configure build this without
manual intervention on almost any type of Unix system. It is
known to work at least on IRIX 4 and 5, SunOS 4, Solaris 2, HP-UX,
Ultrix, OSF/1, AIX, SCO ODT 3.0, Minix, Linux, SEQUENT, and
through the use of automatic feature detection should work on most
other Unix flavors as well. Binaries are available for Macintosh
and PC platforms (for DOS, DOS w/ 32-bit extender, Windows, and
Windows NT).
Python release 1.1
==================
==> This is Python version 1.1.
==> Python 1.1 contains many improvements over 1.0.3, but is almost
backward compatible (though the magic number for .pyc file has
changed). It comes with build instructions for many more non-UNIX
platforms.
==> If you don't know yet what Python is: it's an interpreted,

Troubleshooting
---------------
Here is a selection from the FAQ on various common problems.
3.6. Q. Link errors building Python with STDWIN on SGI IRIX.
A. Rebuild STDWIN, specifying "CC=cc -cckr" in the Makefile.
3.8. Q. Link errors after rerunning the configure script.
A. It is generally necessary to run "make clean" after a configuration
change.
3.9. Q. The python interpreter complains about options passed to a
script (after the script name).
A. You are probably linking with GNU getopt, e.g. through -liberty.
Don't. (If you are using this because you link with -lreadline, use
the readline distributed with Python instead.)
3.10. Q. When building on the SGI, make tries to run python to create
glmodule.c, but python hasn't been built or installed yet.
A. Comment out the line mentioning glmodule.c in Setup and build a
python without gl first; install it or make sure it is in your $PATH,
then edit the Setup file again to turn on the gl module, and make
again. You don't need to do "make clean"; you do need to run "make
Makefile" in the Modules subdirectory (or just run "make" at the
toplevel).
3.13. Q. Other trouble building Python 1.0.2 on platform X.
A. Please email the details to <guido@cwi.nl> and I'll look into it.
See section 3 of the FAQ (in subdirectory Misc of the distribution)
for hints on what can go wrong, and how to fix it.
