return 0 (exceptions don't match). This means that if an ImportError
is raised because exceptions.py can't be imported, the interpreter
will exit "cleanly" with an error message instead of just core
dumping.
PyErr_SetFromErrnoWithFilename(), PyErr_SetFromWindowsErrWithFilename():
Don't test on Py_UseClassExceptionsFlag.
are no longer supported (i.e. -X option is removed).
_PyBuiltin_Init_1(): Don't call initerrors(). This does mean that it
is possible to raise an ImportError before that exception has been
initialized, say because exceptions.py can't be found, or contains
bogosity. See changes to errors.c for how this is handled.
_PyBuiltin_Init_2(): Don't test Py_UseClassExceptionsFlag, just go
ahead and initialize the class-based standard exceptions. If this
fails, we throw a Py_FatalError.
search() functions didn't even work because _fixflags() isn't
idempotent. I'm adding another stop-gap measure so that you can at
least use sre.search() and sre.match() with a zero flags arg.
telnetlib is unable to connect to a few telnet daemons because of
improper IAC handling, heres an attached oneliner to reject WILL
messages which will allow many more telnet daemons to work with it,
namely FreeBSD.
Changed all references to the MAGIC constant to use a global
pyc_magic instead. This global is initially set to MAGIC, but can be
changed by the _PyImport_Init() function to provide for
special features implemented in the compiler which are settable
using command line switches and affect the way PYC files are
generated.
Currently this change is only done for the -U flag.
(1) Added and documented the capability for shlex to handle
lexical-level inclusion and a stack of input sources. Also, the input
stream member is now documented, and the constructor takes an optional
source-filename. The class provides facilities to generate error
messages that track file and line number.
(2) Add a convenience function to generate C-compiler style error
leaders.

[GvR: I changed the __main__ code so that it actually stops at EOF, as
Eric surely intended -- however it returned '' instead of the None he
was testing for.]
Support for the new -U command line option option:
with the option enabled the Python compiler
interprets all "..." strings as u"..." (same with r"..." and
ur"...").
utime(path, NULL) call, setting the atime and mtime of the file to the
current time. The previous signature utime(path, (atime, mtime)) is
of course still allowed.
Follow a suggestion in an /*XXX*/ comment [in com_add()] to speed up
compilation by using supplemental dictionaries to keep track of names
and constants, eliminating quadratic behavior. With this patch in
place, the time to import a 5000-line file with lots of constants [at
the global level] is reduced from 20 seconds to under 3 on my system.
Here's a patch which changes modsupport to add 'u' and 'u#',
to support building Unicode objects from a null-terminated
Py_UNICODE *, and a Py_UNICODE * with length, respectively.
[Conversion from 'U' to 'u' by Fred, based on python-dev comments.]
Note that the use of None for NULL values of the Py_UNICODE* value is
still in; I'm not sure of the conclusion on that issue.
remaining object references if the environment variable PYTHONDUMPREFS
exists. The default behaviour caused problems for background or
otherwise invisible processes that use the debug build of Python.
