Fred Drake 5755ce693d Revise the interface to the profiling and tracing support for the
Python interpreter.

This change adds two new C-level APIs:  PyEval_SetProfile() and
PyEval_SetTrace().  These can be used to install profile and trace
functions implemented in C, which can operate at much higher speeds
than Python-based functions.  The overhead for calling a C-based
profile function is a very small fraction of a percent of the overhead
involved in calling a Python-based function.

The machinery required to call a Python-based profile or trace
function been moved to sysmodule.c, where sys.setprofile() and
sys.setprofile() simply become users of the new interface.

As a side effect, SF bug #436058 is fixed; there is no longer a
_PyTrace_Init() function to declare.

Martin v. Löwis ce9b5a55e1 Encode surrogates in UTF-8 even for a wide Py_UNICODE.
Implement sys.maxunicode.
Explicitly wrap around upper/lower computations for wide Py_UNICODE.
When decoding large characters with UTF-8, represent expected test
results using the \U notation.

Fred Drake d083839fb4 Instead of initializing & interning the strings passed to the profile
and trace functions lazily, which incurs extra argument pushing and checks
in the C overhead for profiling/tracing, create the strings semi-lazily
when the Python code first registers a profile or trace function.  This
simplifies the trampoline into the profile/trace functions.

Guido van Rossum bceccf5f43 Updated version of RISCOS support. SF patch 411213 by Dietmar Schwertberger 2001-04-10 22:07:43 +00:00
Ka-Ping Yee b5c5132d1a Add sys.excepthook.
Update docstring and library reference section on 'sys' module.
New API PyErr_Display, just for displaying errors, called by excepthook.
Uncaught exceptions now call sys.excepthook; if that fails, we fall back
    to calling PyErr_Display directly.
Also comes with sys.__excepthook__ and sys.__displayhook__.

Guido van Rossum 03df3b3bc1 Neil discovered a bad DECREF on warnoptions, that caused repeated
re-initializing Python (Py_Finalize() followed by Py_Initialize()) to
blow up quickly.  With the DECREF removed I can't get it to fail any
more.  (Except it still leaks, but that's probably a separate issue.)

Fred Drake 592f2d6c85 _PySys_Init(): When setting up sys.version_info, use #if/#elif.../#endif
instead of four #if/#endif blocks.  This shortens the

Fred Drake ccede59889 The attempt to protect against MS_WIN16 compilers that do not support long
string literals has not been tested on an MS_WIN16 platform; the trailing
";" was inside the #ifndef MS_WIN16, which should cause an error (missing
semi-colon) when compiled with that symbol #defined.

Thomas Wouters 1e0c2f4bee Create a new section of pyport.h to hold all external function declarations
for systems that are missing those declarations from system include files.
Start by moving a pointy-haired ones from their previous locations to the
new section.

(The gethostname() one, for instance, breaks on several systems, because
some define it as (char *, size_t) and some as (char *, int).)

I purposely decided not to include the summary of used #defines like Tim did
in the first section of pyport.h. In my opinion, the number of #defines
likedly to be used by this section would make such an overview unwieldy. I
would suggest documenting the non-obvious ones, though.

Mark Hammond 440d898230 Added a new debug method sys.gettotalrefcount(), which returns the total number of references on all Python objects. This is only enabled when Py_TRACE_REFS is defined (which includes default debug builds under Windows).
Also removed a redundant cast from sys.getrefcount(), as discussed on the patches list.

Fred Drake 8b4d01d9f9 M.-A. Lemburg <mal@lemburg.com>:

Values are now monotonically increasing with each new release.

Fred Drake 801c08d700 Define version_info to be a tuple (major, minor, micro, level); level
is a string "a2", "b1", "c1", or '' for a final release.

Added version_info and hexversion to the module docstring.

Guido van Rossum be2033697f In PySys_GetObject(), it's possible that tstate->interp->sysdict is
NULL.  In that case, return NULL rather than dumping core.

This fixes PR#91, submitted by Lele Gaifax.

Guido van Rossum a71b5f4e1d Jim Ahlstrom patch: the module doc string is too long for 16-bit VC
1.5.  Omit the second part.
1999-01-14 19:07:00 +00:00
Guido van Rossum e0d7dae3b8 Add sys.hexversion, which is an integer encoding the version in hexadecimal.
In other words, hex(sys.hexversion) == 0x010502b2 for Python 1.5.2b2.
This is derived from the new variable PY_VERSION_HEX defined in patchlevel.h.
(Cute, eh?)

Guido van Rossum 40552d0857 Gack. The module doc string is too long for VC++ 5.0.
However two string literals concatenated are fine!
Hope this doesn't break other platforms.
1998-08-06 03:34:39 +00:00
Guido van Rossum c3bc31e249 Added doc strings. Maybe the doc string for the module itself is a bit
long, but it sure helps!

Guido van Rossum a890e68807 New APIs to write to sys.stdout or sys.stderr using a printf-like interface.
Adapted from code submitted by Just van Rossum.

   PySys_WriteStdout(format, ...)
   PySys_WriteStderr(format, ...)

      The first function writes to sys.stdout; the second to sys.stderr.  When
      there is a problem, they write to the real (C level) stdout or stderr;
      no exceptions are raised (but a pending exception may be cleared when a
      new exception is caught).

      Both take a printf-style format string as their first argument followed
      by a variable length argument list determined by the format string.

      *** WARNING ***

      The format should limit the total size of the formatted output string to
      1000 bytes.  In particular, this means that no unrestricted "%s" formats
      should occur; these should be limited using "%.<N>s where <N> is a
      decimal number calculated so that <N> plus the maximum size of other
      formatted text does not exceed 1000 bytes.  Also watch out for "%f",
      which can print hundreds of digits for very large numbers.
