* New APIs to write to sys.stdout or sys.stderr using a printf-like interface.Guido van Rossum1998-05-121-0/+90
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | 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.
* Oops -- overuse of dabbrev-expand introduced a strange bug, whereGuido van Rossum1998-03-031-1/+1
| | | | instead of 'locals' I was passing 'lock_import' to import_module_ex().
* Add a single Python-wide (!) lock on import. Only one thread at aGuido van Rossum1998-03-031-8/+71
| | | | | | | | | | | | | | | | | | | | 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."
* Fix the handling of errors in Py_FlushLine() in a few places.Guido van Rossum1998-02-281-5/+7
| | | | (Basically, the error is cleared... Like almost everywhere else...)
* Moved clear_carefully() to _PyModule_Clear() in moduleobject.cGuido van Rossum1998-02-191-69/+31
| | | | | | | | | | | | | | | (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.
* Make backup copies of stdin, stdout, stderr as __stdin__, __stdout__,Guido van Rossum1998-02-191-0/+4
| | | | __stderr__. These will be used by the import cleanup.
* Small patches to the DJGPP version of check_case().Guido van Rossum1998-02-181-1/+3
|
* Added DJGPP version of check_case(), by Pit Scrorpion (Hans Nowak).Guido van Rossum1998-02-131-0/+28
| | | | (BTW, the Mac version was by Jack Jansen.)
* Add case checking feature on import.Guido van Rossum1998-02-131-1/+78
| | | | | | | | | | | | | 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.
* Added PyImport_ExecCodeModuleEx(), which adds an extra parameter toGuido van Rossum1998-02-111-5/+25
| | | | | | 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.)
* Set Py_FrozenFlag, to suppress error messages from getpath.c.Guido van Rossum1998-02-061-0/+2
|
* Ehm, three unrelated changes.Guido van Rossum1998-02-061-3/+31
| | | | | | | | | | | | - 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).
* Two more refinements of the cleanup process.Guido van Rossum1998-02-061-3/+52
| | | | | | | | | | | | (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.

* Rewritten PyImport_Cleanup() and its helper, clear_carefully(). TheyGuido van Rossum1998-01-191-12/+98
| | | | | | | | | | | | | | | | | | 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__
