Guido van Rossum 919b83d522 Set Py_FrozenFlag, to suppress error messages from getpath.c. 1998-02-06 22:30:29 +00:00
Guido van Rossum a61691e4e9 Ehm, three unrelated changes.
- Add Py_FrozenFlag, intended to suppress error messages fron
getpath.c in frozen binaries.

- Add Py_GetPythonHome() and Py_SetPythonHome(), intended to allow
embedders to force a different PYTHONHOME.

- Add new interface PyErr_PrintEx(flag); same as PyErr_Print() but
flag determines whether sys.last_* are set or not.  PyErr_Print()
now simply calls PyErr_PrintEx(1).

Guido van Rossum a0fec2b5df Two more refinements of the cleanup process.
(1) Explicitly clear __builtin__._ and sys.{last,exc}_* before
clearing anything else.  These are common places where user values
hide and people complain when their destructors fail.  Since the
modules containing them are deleted *last* of all, they would come too
late in the normal destruction order.  Sigh.

(2) Add some debugging aid to cleanup (after a suggestion by Marc
Lemburg) -- print the names of the modules being cleaned, and (when
-vv is used) print the names of the variables being cleared.

Guido van Rossum 42e8e5d164 Protect PyErr_Format format string argument from overflow. 1998-01-19 22:23:08 +00:00
Guido van Rossum 0d6b49eff2 Protect PyErr_Format format string argument from overflow (ironically,
the error was about a bad format string :-).

Guido van Rossum 15af20a337 Better #ifdefs for NetBSD, taking into account that at least on netBSD
1.3, dlopen() etc. are fully implemented, including dlerror().
From Jaromir Dolecek and Ty Sarna.

Guido van Rossum 4cc462e85b It seems obvious that when Py_Finalize() decides that there's nothing
to do, it should not call sys.exitfunc either...
1998-01-19 22:00:38 +00:00
Guido van Rossum 758eec0172 Rewritten PyImport_Cleanup() and its helper, clear_carefully(). They
now implement the following finalization strategy.

1. Whenever this code deletes a module, its directory is cleared
   carefully, as follows:
   - set all names to None that begin with exactly one underscore
   - set all names to None that don't begin with two underscores
   - clear the directory

2. Modules are deleted in the following order:
   - modules with a reference count of 1, except __builtin__ or __sys__
   - repeat until no more are found with a reference count of 1
   - __main__ if it's still there
   - all remaining modules except __builtin__ or sys
   - sys
   _ __builtin__

Guido van Rossum aa06b0ede5 Plug the most annoying recursive printing problem -- reset '_' to None
before printing and set it to the printed variable *after* printing
(and only when printing is successful).

Guido van Rossum 7d4f68c15f Oops -- '(' is also a legal start character of a new format... 1997-12-19 04:25:23 +00:00
Guido van Rossum e8c27bb3ea Oops! Should've renamed dos_8x3 to dos-8x3 here, too. 1997-12-17 18:57:16 +00:00
Guido van Rossum 330aafb0c2 For base 10, cast unsigned long to long before testing overflow.
This prevents 4294967296 from being an acceptable way to spell zero!

Guido van Rossum d6af46d4ae Need a cast when comparing type object in isinstance() 1997-12-10 05:51:47 +00:00
Guido van Rossum 231a41e708 Add explicit check for correct next character in format at end of
format.  This will complain about illegal formats like "O#" instead of
ignoring the '#'.

Guido van Rossum 19b55f2d17 Fix subtle bug in cleanup code in PyErr_NormalizeException(), detected
by Marc Lemburg.  There's a path through the code where *val is NULL,
but value isn't, and value should be DECREF'ed.
1997-12-09 14:11:39 +00:00
Guido van Rossum 1707aad27c Changed the finalization order again so that the reference count
printing (when Py_DEBUG is defined) happens while there's still a
current thread...

Guido van Rossum 595d7ba069 Jeff Rush: add definition for S_IFMT for VisualAge C/C++ under OS2. 1997-12-05 21:45:29 +00:00
Guido van Rossum 08052c7bb6 Add the flag RTLD_GLOBAL to the dlopen() options.
This exports symbols defined by the loaded extension to other
extensions (loaded later).

(I'm not quite sure about this but suppose it can't hurt...)

Guido van Rossum f5dd914196 Support type objects in isinstance().
E.g. isinstance('',types.StringType) will return true now instead of
raising a TypeError exception.  This is for JPython compatibility.

Guido van Rossum ddc3fb5734 Apply str() to sys.ps1 or sys.ps2 before using them as a prompt, so
you can assign an object whose str() evaluates to the current
directory (or whatever).

Guido van Rossum 8e9ebfd337 os2 patch by Jeff Rush 1997-11-22 21:53:48 +00:00
Guido van Rossum db847bd9ea Plug memory leak in Py_BuildValue when using {...} to construct dictionaries. 1997-11-20 20:35:45 +00:00
Guido van Rossum 2e58ff3ef5 Fix importing of shared libraries from inside packages.
This is a bit of a hack: when the shared library is loaded, the module
name is "package.module", but the module calls Py_InitModule*() with just
"module" for the name.  The shared library loader squirrels away the true
name of the module in _Py_PackageContext, and Py_InitModule*() will
substitute this (if the name actually matches).
1997-11-19 18:53:33 +00:00
Guido van Rossum 858cb73bb2 Two changes (here we go again :-( ).
1) The __builtins__ variable in the __main__ module is set to the
__builtin__ module instead of its __dict__.

2) Get rid of the SIGHUP and SIGTERM handlers.  They can't be made to
work reliably when threads may be in use, they are Unix specific, and
Python programmers can now program this functionality is a safer way
using the signal module.

Guido van Rossum dfed725e2c Fix memory leak in exec statement with code object -- the None returned
by PyEval_EvalCode() on success was never DECREF'ed.

Fix by Bernhard Herzog.

Guido van Rossum 4a1f39a26b Undo half of the previous change :-(
Setting interp->builtins to the __builtin__ module instead of to its
dictionary had the unfortunate side effect of always running in
restricted execution mode :-(

I will check in a different way of setting __main__.__builtins__ to
the __builtin__ module later.

Also, there was a typo -- a comment was unfinished, and as a result
some finalizations were not being executed.

In Bart Simpson style,

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 22348dc0e1 The warning about thread still having a frame now only happens in
verbose mode.
1997-11-03 22:08:36 +00:00
Guido van Rossum 3a44e1b9fb Two independent changes (alas):
- The interp->builtins variable (and hence, __main__.__builtins__) is
once again initialized to the built-in *module* instead of its
dictionary.

- The finalization order is once again changed.  Signals are finalized
relatively early, because (1) it DECREF's the signal handlers, and if
a signal handler happens to be a bound method, deleting it could cause
problems when there's no current thread around, and (2) we don't want
to risk executing signal handlers during finalization.

Guido van Rossum 197346fafe New policy for package imports: only a directory containing
__init__.py (or __init__.pyc/.pyo, whichever applies) is considered a
package.  All other subdirectories are left alone.  Should make Konrad
Hinsen happy!
1997-10-31 18:38:52 +00:00
Guido van Rossum 771c6c8f7a Instead of using _PyImport_Inittab[] directly, use the new "official"
pointer *PyImport_Inittab which is initialized to _PyImport_Inittab.

Guido van Rossum b74eca9349 Change PyEval_SaveThread() and PyEval_RestoreThread() to always do the
tstate swapping.  Only the acquiring and releasing of the lock is
conditional (twice, under ``#ifdef WITH_THREAD'' and inside ``if
(interpreter_lock)'').
