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.

Marc-André Lemburg 99964b86b2 Marc-Andre Lemburg <mal@lemburg.com>:
Changed the API names for setting the default encoding.
These are now in line with the other hooks API names
(no underscores).
2000-06-07 09:13:41 +00:00
Fred Drake 8b4d01d9f9 M.-A. Lemburg <mal@lemburg.com>:
Added APIs to allow setting and querying the system's
current string encoding: sys.set_string_encoding()
and sys.get_string_encoding().

Fred Drake 6d27c1eb32 Simplify creation of the version_info value for clarity, per
suggestion from Greg Stein.
2000-04-13 20:03:20 +00:00
Fred Drake 93a20bf87c Capitulate, changing version_info to a 5-tuple:
major, minor, micro, level, serial

Values are now monotonically increasing with each new release.
2000-04-13 17:44:51 +00:00
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 ffc0f4fb36 Use modern PyArg_ParseTuple style, with function names.
(Mostly.)
2000-03-31 00:38:29 +00:00
Guido van Rossum 43713e5a28 Massive patch by Skip Montanaro to add ":name" to as many
PyArg_ParseTuple() format string arguments as possible.
2000-02-29 13:59:29 +00:00
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.

Barry Warsaw 54892c4b2c _PySys_Init(): Nailed small memory leak. The stringobject created for
sys.version was missing a Py_XDECREF().
1999-01-27 16:33:19 +00:00
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 8442af35fe Patches for mywrite() by Marc Lemburg: save/restore the error state
reliably; check return value of vsprintf().
1998-10-12 18:22:10 +00:00
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!
1998-06-27 19:43:25 +00:00
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.
1998-05-12 14:59:24 +00:00
Guido van Rossum bd36dbaaa5 Make backup copies of stdin, stdout, stderr as __stdin__, __stdout__,
__stderr__.  These will be used by the import cleanup.
1998-02-19 20:53:06 +00:00
Guido van Rossum 25c649fdf2 Get rid of another reference to _PyImport_Inittab (now a static array)
that should be PyImport_Inittab (a new pointer initialized to point to
the array).

Guido van Rossum 25ce566661 The last of the mass checkins for separate (sub)interpreters.
Everything should now work again.

more detail.
1997-08-02 03:10:38 +00:00
Guido van Rossum 534ac094f9 Removed a bunch of extern declarations of functions that are now
properly declared in Python.h.

Guido van Rossum 1254d79dfa Use #ifdef in stead of #if (Jack) 1997-05-20 15:57:25 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management.
All per-thread globals are moved into a struct which is manipulated
separately.
1997-05-05 20:56:21 +00:00
Guido van Rossum bb5c6f8529 Oops, forgot one: inittab. 1997-04-29 20:42:30 +00:00
Guido van Rossum 65bf9f265e Quickly renamed. 1997-04-29 18:33:38 +00:00
Guido van Rossum c474deaaf6 Expand one level of symbolic link in sys.argv[0] before inserting its
dirname in sys.path.  This means that you can create a symbolic link
foo in /usr/local/bin pointing to /usr/yourname/src/foo/foo.py, and
then invoking foo will insert /usr/yourname/src/foo in sys.path, not
/usr/local/bin.  This makes it easier to have multifile programs
(before, the program would have to do an os.readlink(sys.argv[0])
itself and insert the resulting directory in sys.path -- Grail does
this).

Note that the expansion is only used for sys.path; sys.argv[0] is
still the original, unadorned filename (/usr/local/bin/foo in the
example).
1997-04-25 15:38:31 +00:00
Guido van Rossum 43f1b8d6e4 Added optional interface for dynamic execution profile (to be gathered
in ceval.c).

Guido van Rossum 8b9ea873ad Use MS_DLL_ID as sys.winver 1996-08-23 18:14:47 +00:00
Guido van Rossum 94a9667f1a Always insert script directory in front of sys.path -- if there's no
sys.argv, insert "".  Note that "." is removed as a default component
of the path (see changes to getpath.c and Setup.in).
1996-07-30 20:35:50 +00:00
Guido van Rossum a63d9f4d9f As a side effect of calling PySys_SetArgv (setpythonargv), the
directory containing argv[0] is inserted in front of sys.path.
If argv[0] contains no directory, an empty string is inserted.
If argv is empty, nothing happens.

Guido van Rossum b0352fa3fc fix args options for setcheckinterval 1996-01-12 01:15:01 +00:00
Sjoerd Mullender 6ec3c653da Implemented two new functions in sys:
getcounts() returns a list of counts of allocations and
		deallocations for all different object types.
	getobjects(n [, type ]) returns a list of recently allocated
		and not-yet-freed objects of the given type (all
		objects if no type given).  Only the n most recent
		(all if n==0) objects are returned.
getcounts is only available if compiled with -DCOUNT_ALLOCS,
getobjects is only available if compiled with -DTRACE_REFS.  Note that
everything must be compiled with these options!

1995-01-04 19:12:13 +00:00
Guido van Rossum 1ae940a587 Lots of changes, most minor (fatal() instead of abort(), use of
err_fetch/err_restore and so on).  But...
NOTE: import.c has been rewritten and all the DL stuff is now in the
new file importdl.c.

Guido van Rossum 3165fe6a56 Modified most (but not yet all) I/O to always go through sys.stdout or
sys.stderr or sys.stdin, and to work with any object as long as it has
a write() (respectively readline()) methods.  Some functions that took
a FILE* argument now take an object* argument.
