Martin v. Löwis 00f1e3f5a5 Patch #534304: Implement phase 1 of PEP 263. 2002-08-04 17:29:52 +00:00
Jack Jansen 21ed16acbe Added one call to Py_Main(), for OSX framework builds only, that will get the
actual script to run in case we are running from an applet. If we are indeed
running an applet we skip the normal option processing leaving it all to the
applet code.

This allows us to get use the normal python binary in the Python.app bundle,
giving us all the normal command line options through PythonLauncher while
still allowing Python.app to be used as the template for building applets.

Consequently, pythonforbundle is gone, and Mac/Python/macmain.c isn't used
on OSX anymore.

Mark Hammond fe51c6d66e Excise DL_EXPORT/DL_IMPORT from Modules/*. Required adding a prototype
for Py_Main().

Thanks to Kalle Svensson and Skip Montanaro for the patches.

Thomas Heller 085358a3e2 New functions for extension writers on Windows:
PyErr_SetExcFromWindowsErr(), PyErr_SetExcFromWindowsErrWithFilename().

Similar to PyErr_SetFromWindowsErrWithFilename() and
PyErr_SetFromWindowsErr(), but they allow to specify
the exception type to raise. Available on Windows.

See SF patch #576458.
2002-07-29 14:27:41 +00:00
Mark Hammond a290527376 Excise DL_IMPORT/EXPORT from object.h, and related files. This patch
also adds 'extern' to PyAPI_DATA rather than at each declaration, as
discussed with Tim and Guido.

Martin v. Löwis 6f18a3c124 Define _XOPEN_SOURCE and _GNU_SOURCE in pyconfig.h, to have them
available in the configure tests already.

Mark Hammond 8235ea1c3a Land Patch [ 566100 ] Rationalize DL_IMPORT and DL_EXPORT. 2002-07-19 06:55:41 +00:00
Jeremy Hylton 5a7ef7e2b5 Define _XOPEN_SOURCE in configure and Python.h.
This gets compilation of posixmodule.c to succeed on Tru64 and does no
harm on Linux.  We may need to undefine it on some platforms, but
let's wait and see.

Martin says:

> I think it is generally the right thing to define _XOPEN_SOURCE on
> Unix, providing a negative list of systems that cannot support this
> setting (or preferably solving whatever problems remain).
>
> I'd put an (unconditional) AC_DEFINE into configure.in early on; it
> *should* go into confdefs.h as configure proceeds, and thus be active
> when other tests are performed.

Jeremy Hylton 938ace69a0 staticforward bites the dust.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure.  Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers.  (In
fact, we expect that the compilers are all fixed eight years later.)

I'm leaving staticforward and statichere defined in object.h as
static.  This is only for backwards compatibility with C extensions
that might still use it.

XXX I haven't updated the documentation.

ULONGLONGMAX -- removed; never used
2002-07-12 05:01:20 +00:00
Tim Peters 3459251d5a object.h special-build macro minefield: renamed all the new lexical
helper macros to something saner, and used them appropriately in other
files too, to reduce #ifdef blocks.

classobject.c, instance_dealloc():  One of my worst Python Memories is
trying to fix this routine a few years ago when COUNT_ALLOCS was defined
but Py_TRACE_REFS wasn't.  The special-build code here is way too
complicated.  Now it's much simpler.  Difference:  in a Py_TRACE_REFS
build, the instance is no longer in the doubly-linked list of live
objects while its __del__ method is executing, and that may be visible
via sys.getobjects() called from a __del__ method.  Tough -- the object
is presumed dead while its __del__ is executing anyway, and not calling
_Py_NewReference() at the start allows enormous code simplification.

typeobject.c, call_finalizer():  The special-build instance_dealloc()
pain apparently spread to here too via cut-'n-paste, and this is much
simpler now too.  In addition, I didn't understand why this routine
was calling _PyObject_GC_TRACK() after a resurrection, since there's no
plausible way _PyObject_GC_UNTRACK() could have been called on the
object by this point.  I suspect it was left over from pasting the
instance_delloc() code.  Instead asserted that the object is still
tracked.  Caution:  I suspect we don't have a test that actually
exercises the subtype_dealloc() __del__-resurrected-me code.

Tim Peters 57f4ddd6c1 Uglified the new Py_REF_DEBUG (etc) lexical helper macro definitions so
that their uses can be prettier.  I've come to despise the names I picked
for these things, though, and expect to change all of them -- I changed
a bunch of other files to use them (replacing #ifdef blocks), but the
names were so obscure out of context that I backed that all out again.

Thomas Heller 6b17abf6c0 Fix SF Bug 564931: compile() traceback must include filename. 2002-07-09 09:23:27 +00:00
Tim Peters 7c321a80f9 The Py_REF_DEBUG/COUNT_ALLOCS/Py_TRACE_REFS macro minefield: added
more trivial lexical helper macros so that uses of these guys expand
to nothing at all when they're not enabled.  This should help sub-
standard compilers that can't do a good job of optimizing away the
previous "(void)0" expressions.

Py_DECREF:  There's only one definition of this now.  Yay!  That
was that last one in the family defined multiple times in an #ifdef
maze.

Py_FatalError():  Changed the char* signature to const char*.

_Py_NegativeRefcount():  New helper function for the Py_REF_DEBUG
expansion of Py_DECREF.  Calling an external function cuts down on
the volume of generated code.  The previous inline expansion of abort()
didn't work as intended on Windows (the program often kept going, and
the error msg scrolled off the screen unseen).  _Py_NegativeRefcount
calls Py_FatalError instead, which captures our best knowledge of
how to abort effectively across platforms.
2002-07-09 02:57:01 +00:00
Tim Peters 4be93d0e84 Rearranged and added comments to object.h, to clarify many things
that have taken me "too long" to reverse-engineer over the years.
Vastly reduced the nesting level and redundancy of #ifdef-ery.
Took a light stab at repairing comments that are no longer true.

sys_gettotalrefcount():  Changed to enable under Py_REF_DEBUG.
It was enabled under Py_TRACE_REFS, which was much heavier than
necessary.  sys.gettotalrefcount() is now available in a
Py_REF_DEBUG-only build.
2002-07-07 19:59:50 +00:00
Tim Peters 803526b9e2 Trashcan cleanup: Now that cyclic gc is always there, the trashcan
mechanism is no longer evil:  it no longer plays dangerous games with
the type pointer or refcounts, and objects in extension modules can play
along too without needing to edit the core first.

Rewrote all the comments to explain this, and (I hope) give clear
guidance to extension authors who do want to play along.  Documented
all the functions.  Added more asserts (it may no longer be evil, but
it's still dangerous <0.9 wink>).  Rearranged the generated code to
make it clearer, and to tolerate either the presence or absence of a
semicolon after the macros.  Rewrote _PyTrash_destroy_chain() to call
tp_dealloc directly; it was doing a Py_DECREF again, and that has all
sorts of obscure distorting effects in non-release builds (Py_DECREF
was already called on the object!).  Removed Christian's little "embedded
change log" comments -- that's what checkin messages are for, and since
it was impossible to correlate the comments with the code that changed,
I found them merely distracting.
2002-07-07 05:13:56 +00:00
Tim Peters 943382c8e5 Removed WITH_CYCLE_GC #ifdef-ery. Holes:
+ I'm not sure what to do about configure.in.  Left it alone.

+ Ditto pyexpat.c.  Fred or Martin will know what to do.
2002-07-07 03:59:34 +00:00
Tim Peters 1de41bfbc0 Stop trying to cater to platforms with a broken HUGE_VAL definition. It
breaks other platforms (in this case, the hack for broken Cray systems in
turn caused failure on a Mac system broken in a different way).
2002-07-03 03:31:20 +00:00
Tim Peters 6fc13d9595 Finished transitioning to using gc_refs to track gc objects' states.
This was mostly a matter of adding comments and light code rearrangement.
Upon untracking, gc_next is still set to NULL.  It's a cheap way to
provoke memory faults if calling code is insane.  It's also used in some
way by the trashcan mechanism.
2002-07-02 18:12:35 +00:00
Tim Peters ea405639bf Reserved another gc_refs value for untracked objects. Every live gc
object should now have a well-defined gc_refs value, with clear transitions
among gc_refs states.  As a result, none of the visit_XYZ traversal
callbacks need to check IS_TRACKED() anymore, and those tests were removed.
(They were already looking for objects with specific gc_refs states, and
the gc_refs state of an untracked object can no longer match any other
gc_refs state by accident.)
Added more asserts.
I expect that the gc_next == NULL indicator for an untracked object is
now redundant and can also be removed, but I ran out of time for this.

Michael W. Hudson 5efaf7eac8 This is my nearly two year old patch
[ 400998 ] experimental support for extended slicing on lists

somewhat spruced up and better tested than it was when I wrote it.

Includes docs & tests.  The whatsnew section needs expanding, and arrays
should support extended slices -- later.

Jason Tishler bc48826dc2 Patch #555929: Cygwin AH_BOTTOM cleanup patch (*** version 2 ***)
This patch complies with the following request found
near the top of configure.in:

# This is for stuff that absolutely must end up in pyconfig.h.
# Please use pyport.h instead, if possible.

I tested this patch under Cygwin, Win32, and Red
Hat Linux. Python built and ran successfully on
each of these platforms.

Neal Norwitz d68f5171eb As discussed on python-dev, add a mechanism to indicate features
that are in the process of deprecation (PendingDeprecationWarning).
Docs could be improved.

Michael W. Hudson e5df1058f1 Silly typo. 2002-05-27 14:05:31 +00:00
Guido van Rossum cacfc07d08 - A new type object, 'string', is added. This is a common base type
for 'str' and 'unicode', and can be used instead of
  types.StringTypes, e.g. to test whether something is "a string":
  isinstance(x, string) is True for Unicode and 8-bit strings.  This
  is an abstract base class and cannot be instantiated directly.

Guido van Rossum 2d3b986480 Disambiguate the grammar for backtick.
The old syntax suggested that a trailing comma was OK inside backticks,
but in fact (due to ideosyncrasies of pgen) it was not.  Fix the grammar
to avoid the ambiguity.  Fred: you may want to update the refman.

Tim Peters 8b078f95e0 Moving pymalloc along.
As threatened, PyMem_{Free, FREE} also invoke the object deallocator now
when pymalloc is enabled (well, it does when pymalloc isn't enabled too,
but in that case "the object deallocator" is plain free()).

This is maximally backward-compatible, but it leaves a bitter aftertaste.

Also massive reworking of comments.
2002-04-28 04:11:46 +00:00
Guido van Rossum 7dab2426ca - New builtin function enumerate(x), from PEP 279. Example:
enumerate("abc") is an iterator returning (0,"a"), (1,"b"), (2,"c").
  The argument can be an arbitrary iterable object.

Walter Dörwald de02bcb265 Apply patch diff.txt from SF feature request
http://www.python.org/sf/444708

This adds the optional argument for str.strip
to unicode.strip too and makes it possible
to call str.strip with a unicode argument
and unicode.strip with a str argument.

Tim Peters 51e7f5caba Moving pymalloc along.
+ Redirect PyMem_{Del, DEL} to the object allocator's free() when
  pymalloc is enabled.  Needed so old extensions can continue to
  mix PyObject_New with PyMem_DEL.

+ This implies that pgen needs to be able to see the PyObject_XYZ
  declarations too.  pgenheaders.h now includes Python.h.  An
  implication is that I expect obmalloc.o needs to get linked into
  pgen on non-Windows boxes.

+ When PYMALLOC_DEBUG is defined, *all* Py memory API functions
  now funnel through the debug allocator wrapper around pymalloc.
  This is the default in a debug build.

+ That caused compile.c to fail:  it indirectly mixed PyMem_Malloc
  with raw platform free() in one place.  This is verbotten.
2002-04-22 02:33:27 +00:00
Tim Peters 058b141ef7 Py_UniversalNewlineFread(): Many changes.
+ Continued looping until n bytes in the buffer have been filled, not
  just when n bytes have been read from the file.  This repairs the
  bug that f.readlines() only sucked up the first 8192 bytes of the file
  on Windows when universal newlines was enabled and f was opened in
  U mode (see Python-Dev -- this was the ultimate cause of the
  test_inspect.py failure).

+ Changed prototye to take a char* buffer (void* doesn't make much sense).

+ Squashed size_t vs int mismatches (in particular, besides the unsigned
  vs signed distinction, size_t may be larger than int).

+ Gets out under all error conditions now (it's possible for fread() to
  suffer an error even if it returns a number larger than 0 -- any
  "short read" is an error or EOF condition).

+ Rearranged and simplified declarations.
2002-04-21 07:29:14 +00:00
Jack Jansen 7b8c7546eb Mass checkin of universal newline support.
Highlights: import and friends will understand any of \r, \n and \r\n
as end of line. Python file input will do the same if you use mode 'U'.
Everything can be disabled by configuring with --without-universal-newlines.

See PEP278 for details.
2002-04-14 20:12:41 +00:00
Tim Peters 0e871188e8 _PyObject_DebugDumpStats: renamed to _PyObject_DebugMallocStats.
Added code to call this when PYMALLOC_DEBUG is enabled, and envar
PYTHONMALLOCSTATS is set, whenever a new arena is obtained and once
late in the Python shutdown process.
2002-04-13 08:29:14 +00:00
Tim Peters af3e8de580 First stab at rationalizing the PyMem_ API. Mixing PyObject_xyz with
PyMem_{Del, DEL} doesn't work yet (compilation problems).

pyport.h:  _PyMem_EXTRA is gone.

pmem.h:  Repaired comments.  PyMem_{Malloc, MALLOC} and
PyMem_{Realloc, REALLOC} now make the same x-platform guarantees when
asking for 0 bytes, and when passing a NULL pointer to the latter.

object.c:  PyMem_{Malloc, Realloc} just call their macro versions
now, since the latter take care of the x-platform 0 and NULL stuff
by themselves now.

pypcre.c, grow_stack():  So sue me.  On two lines, this called
PyMem_RESIZE to grow a "const" area.  It's not legit to realloc a
const area, so the compiler warned given the new expansion of
PyMem_RESIZE.  It would have gotten the same warning before if it
had used PyMem_Resize() instead; the older macro version, but not the
function version, silently cast away the constness.  IMO that was a wrong
thing to do, and the docs say the macro versions of PyMem_xyz are
deprecated anyway.  If somebody else is resizing const areas with the
macro spelling, they'll get a warning when they recompile now too.
2002-04-12 07:22:56 +00:00
Tim Peters e9e7452505 First cut at repairing out-of-date comments; make alignment of macro defs

Neil Schemenauer 3e7b893899 Remove PyMalloc_* symbols. PyObject_Malloc now uses pymalloc if

Make PyObject_GC_Track and PyObject_GC_UnTrack functions instead of
trivial macros wrapping functions.
