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 :-).

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.

4cc462e85b It seems obvious that when Py_Finalize() decides that there's nothing 
to do, it should not call sys.exitfunc either...

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__

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).

330aafb0c2 For base 10, cast unsigned long to long before testing overflow. 
This prevents 4294967296 from being an acceptable way to spell zero!

d6af46d4ae Need a cast when comparing type object in isinstance() 1997-12-10 05:51:47 +00:00

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 '#'.

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.

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...

595d7ba069 Jeff Rush: add definition for S_IFMT for VisualAge C/C++ under OS2. 1997-12-05 21:45:29 +00:00

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...)

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.

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).

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).

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.
