Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

tab-setting magic much smarter, more correct, and more easily
extensible.

Guido van Rossum 80c7bcf667 The previous fix was still broken; the Py_END_ALLOW_THREADS macro was
never executed because of a return statement.  Sigh.
1998-08-29 16:03:27 +00:00
Guido van Rossum 8efa47b63e We now assume that PyOS_Readline() is called with the interpreter lock
held.  It releases the lock around the call to the function pointed to by
PyOS_ReadlineFunctionPointer (default PyOS_StdioReadline()).

Guido van Rossum 47fbc4049e Add a version of PySys_WriteStderr() that writes to stderr, so we can
use it in tokenizer.c.

Guido van Rossum 54758fa8ca Swap two statements in the dedent check loop. This makes absolutely
no difference, but avoids triggering an optimizer bug in the AIX
compiler where the loop unrolling does the wrong thing...
1998-02-16 22:18:00 +00:00
Guido van Rossum 35685240a9 Fixed the bug in searching for triple quotes -- change the 'quote2'
variable from a pointer to an index, so a realloc() of the buffer
won't disturb it.  Problem found by Vladimir Marangozov.
1998-02-16 15:42:50 +00:00
Guido van Rossum cf57d8b8c9 tok_nextc() should return unsigned characters, to avoid mistaking
'\377' for EOF.

Guido van Rossum 7bf22de753 Patch for QNX, by Chris Herborth. 1997-12-02 20:34:19 +00:00
Guido van Rossum 359bcaa539 This fix (across 4 files in 3 directories) solves a subtle problem with
signal handlers in a fork()ed child process when Python is compiled with
thread support.  The bug was reported by Scott <scott@chronis.icgroup.com>.

What happens is that after a fork(), the variables used by the signal
module to determine whether this is the main thread or not are bogus,
and it decides that no thread is the main thread, so no signals will
be delivered.

The solution is the addition of PyOS_AfterFork(), which fixes the signal
module's variables.  A dummy version of the function is present in the
intrcheck.c source file which is linked when the signal module is not
used.

Guido van Rossum fbd64c8790 Restructured quite a bit, hopefully Lee Busby will find this useful.
Also grandly renamed.

Here's the new interface:

When WITH_READLINE is defined, two functions are defined:

  - PyOS_GnuReadline (what used to be my_readline() with WITH_READLINE)
  - PyOS_ReadlineInit (for Dave Ascher)

Always, these functions are defined:

  - PyOS_StdioReadline (what used to be my_readline() without WITH_READLINE)
  - PyOS_Readline (the interface used by tokenizer.c and [raw_]input().

There's a global function pointer PyOS_ReadlineFunctionPointer,
initialized to NULL.  When PyOS_Readline finds this to be NULL, it
sets it to either PyOS_GnuReadline or PyOS_StdioReadline depending on
which one makes more sense (i.e. it uses GNU only if it is defined
*and* stdin is indeed a tty device).

An embedding program that has its own wishes can set the function
pointer to a function of its own design.  It should take a char*
prompt argument (which may be NULL) and return a string *ending in a
\n character* -- or "" for EOF or NULL for a user interrupt.
