Guido van Rossum 1e162d3753 Implement round() slightly different, so that for negative ndigits no
additional errors happen in the last step.  The trick is to avoid
division by 0.1**n -- multiply by 10.0**n instead.

Guido van Rossum a937d14898 Fred's right -- we need PyList_SET_ITEM(). 1998-04-24 18:22:02 +00:00
Guido van Rossum 507338e5ca In-line the code in range() to set the list items; there's really no
need to call PyList_SetItem(v,i,w) when PyList_GET_ITEM(v,i)=w {sic}
will do.

Guido van Rossum ede0439cd8 /* An extension mechanism to store arbitrary additional per-thread state.
PyThreadState_GetDict() returns a dictionary that can be used to hold such
   state; the caller should pick a unique key and store its state there.  If
   PyThreadState_GetDict() returns NULL, an exception has been raised (most
   likely MemoryError) and the caller should pass on the exception. */

1998-03-13 21:30:14 +00:00
Guido van Rossum a5568d349b Support for frozen packages, matching the revamped Tools/freeze.
Frozen packages are indicated by a negative size (the code string
is the __import__.py file).  A frozen package module has its __path__
set to a string, the package name.

Guido van Rossum d65911b3f3 Oops -- overuse of dabbrev-expand introduced a strange bug, where
instead of 'locals' I was passing 'lock_import' to import_module_ex().
1998-03-03 22:33:27 +00:00
Guido van Rossum 75acc9ca1c Add a single Python-wide (!) lock on import. Only one thread at a
time can be in PyImport_ImportModuleEx().  Recursive calls from the
same thread are okay.

Potential problems:

- The lock should really be part of the interpreter state rather than
global, but that would require modifying more files, and I first want
to figure out whether this works at all.

- One could argue that the lock should be per module -- however that
would be complicated to implement.  We would have to have a linked
list of locks per module name, *or* invent a new object type to
represent a lock, so we can store the locks in the module or in a
separate dictionary.  Both seem unwarranted.  The one situation where
this can cause problems is when loading a module takes a long time,
e.g. when the module's initialization code interacts with the user --
during that time, no other threads can run.  I say, "too bad."

Guido van Rossum 0829c754bb Fix the handling of errors in Py_FlushLine() in a few places.
(Basically, the error is cleared...  Like almost everywhere else...)
1998-02-28 04:31:39 +00:00
Guido van Rossum 05f9dce34f Moved clear_carefully() to _PyModule_Clear() in moduleobject.c
(modified) and use that.

Some differences in the cleanup algorithm:

- Clear __main__ before the other modules.

- Delete more sys variables: including ps1, ps2, exitfunc, argv, and
even path -- this will prevent new imports!

- Restore stdin, stdout, stderr from __stdin__, __stdout__,
__stderr__, effectively deleting hooks that the user might have
installed -- so their (the hooks') destructors will run.
1998-02-19 20:58:44 +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.

Guido van Rossum aeca79b0f6 Small patches to the DJGPP version of check_case(). 1998-02-18 16:21:00 +00:00
Guido van Rossum 4d1b3b921d Added DJGPP version of check_case(), by Pit Scrorpion (Hans Nowak).
(BTW, the Mac version was by Jack Jansen.)
1998-02-13 23:27:59 +00:00
Guido van Rossum 0980bd9233 Add case checking feature on import.
This is an option for OS-es with case-insensitive but case-preserving
filesystems.  It is currently supported for Win32 and MacOS.  To
enable it, #define CHECK_IMPORT_CASE in your platform specific
config.h.  It is enabled by default on those systems where it is
supported.  On Win32, it can be disabled at runtime by setting the
environment variable PYTHONCASEOK (to any value).

When enabled, the feature checks that the case of the requested module
name matches that of the filename found in the filesystem, and raises
a NameError exception when they don't match.
1998-02-13 17:18:36 +00:00
Guido van Rossum e32bf6ead2 Added PyImport_ExecCodeModuleEx(), which adds an extra parameter to
pass it the true file.  This is used to set __file__ properly, instead
of believing what the code object carries with it.  (If the pointer
is NULL, the code object's co_filename is still used.)

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).
1998-02-06 22:27:24 +00:00
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 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().

1998-01-19 22:03:52 +00:00
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 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.

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 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.
