Antoine Pitrou 4879a963d4 Issue #18756: os.urandom() now uses a lazily-opened persistent file descriptor, so as to avoid using many file descriptors when run in parallel from multiple threads. 2013-08-31 00:26:02 +02:00
Victor Stinner 55a1220bdb pythonrun.c: use MAXPATHLEN instead of PATH_MAX
PATH_MAX is not available on "MIPS IRIX 6.5.30 [SB] 3.x" buildbot

Victor Stinner daf455554b Issue #18571: Implementation of the PEP 446: file descriptors and file handles
are now created non-inheritable; add functions os.get/set_inheritable(),
os.get/set_handle_inheritable() and socket.socket.get/set_inheritable().

Antoine Pitrou 7eaf3f7080 Issue #18808: Non-daemon threads are now automatically joined when a sub-interpreter is shutdown (it would previously dump a fatal error). 2013-08-25 19:48:18 +02:00
Christian Heimes ad73a9cf97 Issue #16400: Add command line option for isolated mode.
-I

    Run Python in isolated mode. This also implies -E and -s. In isolated mode
    sys.path contains neither the script’s directory nor the user’s
    site-packages directory. All PYTHON* environment variables are ignored,
    too. Further restrictions may be imposed to prevent the user from
    injecting malicious code.

Victor Stinner 1c8f059019 Issue #18520: Add a new PyStructSequence_InitType2() function, same than
PyStructSequence_InitType() except that it has a return value (0 on success,
-1 on error).

 * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure
 * Fix also some calls to PyDict_SetItemString(): handle error

Victor Stinner 26f91999b4 Close #18469: Replace PyDict_GetItemString() with _PyDict_GetItemId() in structseq.c
_PyDict_GetItemId() is more efficient: it only builds the Unicode string once.
Identifiers (dictionary keys) are now created at Python initialization, and if
the creation failed, Python does exit with a fatal error.

Before, PyDict_GetItemString() failure was not handled: structseq_new() could
call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could
also crash.

Victor Stinner 49fc8ece81 Issue #18203: Add _PyMem_RawStrdup() and _PyMem_Strdup()
Replace strdup() with _PyMem_RawStrdup() or _PyMem_Strdup(), depending if the
GIL is held or not.

Victor Stinner 51fa458d0a Issue #18203: Fix Py_Finalize(): destroy the GIL after the last call to
PyMem_Malloc() or PyObject_Malloc().

For example, PyCFunction_Fini() calls PyObject_GC_Del() which calls
PyObject_FREE().

Brett Cannon 4c14b5de1c #17115,17116: Have modules initialize the __package__ and __loader__
attributes to None.

The long-term goal is for people to be able to rely on these
attributes existing and checking for None to see if they have been
set. Since import itself sets these attributes when a loader does not
the only instances when the attributes are None are from someone
overloading __import__() and not using a loader or someone creating a
module from scratch.

This patch also unifies module initialization. Before you could have
different attributes with default values depending on how the module
object was created. Now the only way to not get the same default set
of attributes is to circumvent initialization by calling
ModuleType.__new__() directly.

Christian Heimes 04ac4c1cb8 Issue #15895: my analysis was slightly off. The FILE pointer is only leaked when set_main_loader() fails for a pyc file with closeit=0. In the success case run_pyc_file() does its own cleanup of the fp. I've changed the code to use another FILE ptr for pyc files and moved the fclose() to PyRun_SimpleFileExFlags() to make it more obvious what's happening. 2012-09-11 15:47:28 +02:00

Victor Stinner d5698cbbca Fix initialization of the faulthandler module
faulthandler requires the importlib if "-X faulthandler" option is present on
the command line, so initialize faulthandler after importlib.

Add also an unit test.

Nick Coghlan 3f94cbf9eb Actually initialize __main__.__loader__ with loader instances, not the corresponding type objects 2012-07-15 19:10:39 +10:00
Nick Coghlan 85e729ec3b Take the first step in resolving the messy pkgutil vs importlib edge cases by basing pkgutil explicitly on importlib, deprecating its internal import emulation and setting __main__.__loader__ correctly so that runpy still works (Affects #15343, #15314, #15357) 2012-07-15 18:09:52 +10:00

Brett Cannon e0d88a173c Issue #14605: Make explicit the entries on sys.path_hooks that used to
be implicit.

Added a warning for when sys.path_hooks is found to be empty. Also
changed the meaning of None in sys.path_importer_cache to represent
trying sys.path_hooks again (an interpretation of previous semantics).
Also added a warning for when None was found.

The long-term goal is for None in sys.path_importer_cache to represent
the same as imp.NullImporter: no finder found for that sys.path entry.

Brett Cannon 6f44d66bc4 Issue #13959: Rename imp to _imp and add Lib/imp.py and begin

To start, imp.new_module() has been rewritten in pure Python, put into
importlib (privately) and then publicly exposed in imp.

Brett Cannon fd0741555b Issue #2377: Make importlib the implementation of __import__().
importlib._bootstrap is now frozen into Python/importlib.h and stored
as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen
code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().
