* Fix the import machinery if there is an error on sys.path or sys.meta_pathVictor Stinner2011-09-151-4/+4
| | | | | | find_module() now raises a RuntimeError, instead of ImportError, on an error on sys.path or sys.meta_path because load_package() and import_submodule() returns None and clear the exception if a ImportError occurred.

* Turned out that if you used explicit relative import syntaxBrett Cannon2010-05-201-1/+2
| | | | | | | | | (e.g. from .os import sep) and it failed, import would still try the implicit relative import semantics of an absolute import (from os import sep). That's not right, so when level is negative, only do explicit relative import semantics. Fixes issue #7902. Thanks to Meador Inge for the patch.

* Fix issue #1590864, multiple threads and fork() can cause deadlocks, byThomas Wouters2009-09-161-19/+12
| | | | | | | | | | | | | | | | | | | | | | acquiring the import lock around fork() calls. This prevents other threads from having that lock while the fork happens, and is the recommended way of dealing with such issues. There are two other locks we care about, the GIL and the Thread Local Storage lock. The GIL is obviously held when calling Python functions like os.fork(), and the TLS lock is explicitly reallocated instead, while also deleting now-orphaned TLS data. This only fixes calls to os.fork(), not extension modules or embedding programs calling C's fork() directly. Solving that requires a new set of API functions, and possibly a rewrite of the Python/thread_*.c mess. Add a warning explaining the problem to the documentation in the mean time. This also changes behaviour a little on AIX. Before, AIX (but only AIX) was getting the import lock reallocated, seemingly to avoid this very same problem. This is not the right approach, because the import lock is a re-entrant one, and reallocating would do the wrong thing when forking while holding the import lock. Will backport to 2.6, minus the tiny AIX behaviour change.
