- BZ#603073
The pydoc -k command performs a keyword search of the synopses in all installed Python modules. This command failed on modules that did not import, resulting in a traceback. pydoc -k now ignores modules that have import exceptions, allowing searches on the remaining modules.
- BZ#625393
A minor incompatibility with SELinux in one of the commands module selftests was corrected.
- BZ#625395
The python-tests subpackage was missing some test files and directories used by the selftests for lib2to3. This update adds the missing content to the subpackage.
- BZ#626756
Previously, the in operator for dbm mappings erroneously returned False for all keys on big-endian 64-bit builds of Python (64-bit PowerPC and IBM System z). This update fixes this issue.
- BZ#634944
A harmless but unnecessary RPATH directive from the _sqlite3.so module was removed. Execution and "#!" lines from .py files within the standard library that did not require these lines were also removed.
- BZ#637895
Previously, the urllib2 module ignored the no_proxy variable for the FTP scheme. This could lead to programs such as yum erroneously accessing a proxy server for ftp:// URLs covered by a no_proxy exclusion. The no_proxy variable now overrides the ftp_proxy variable, enforcing this exclusion.
- BZ#639222
Previously, the IDLE Python IDE used a hard-coded port (8833) when communicating between the shell and the execution sub-processes. Attempts to use more than one instance of IDLE on one computer failed with a "Port Binding Error" dialog box. This update backports a patch from Python 2.7 to use an ephemeral port instead, resolving this issue.
- BZ#639392
On AMD64 and Intel 64 architectures, running gdb (configured using the --with-python option) on python applications to generate backtraces caused a traceback error. python-gdb.py, the python module that deals with the case of debugging a python process, was updated to prevent this.
- BZ#649274
Using an invalid username or password while attempting to authenticate against HTTPS via the urllib2 module resulted in infinite recursion. This behavior has been patched, and urllib22 now attempts authentication a maximum of five times before authentication is considered failed.
- BZ#650588
Previously, Python programs that used ulimit -n to enable communication with large numbers of subprocesses could still monitor only 1024 file descriptors at a time, due to the subprocess module using the select system call. This could cause an exception:
ValueError: filedescriptor out of range in select()
The module now uses the poll system call, removing this limitation.
- BZ#669847
Basic HTTP authentication via the urllib2 module was limited to six requests because the retried attribute was not reset when authentication was successful. This attribute is now reset, and authentication requests work as expected.
- BZ#677392
The test_structmembers unit test failed on big-endian 64-bit builds of Python (64-bit PowerPC and IBM System z) because a variable was not well-defined. The variable is now defined correctly, and the unit test works as expected. Note that this issue was discovered and corrected during development, and was not encountered in production systems in the field.
- BZ#684991
Upgrading Python removed a call to the PyErr_Clear() method, which exposed an assertion failure in RhythmBox that resulted in RhythmBox crashing. Python now compensates for the RhythmBox assertion failure.
- BZ#690315
A race condition was discovered in python Makefile.pre.in. The make command interprets a make rule with two dependents as two copies of the rule. On machines with more than one core, this could lead to race conditions in which the compiler attempted to read a partially-overwritten file. This resulted in syntax or link errors when attempting to build python on machines with multiple cores. A check has been added to prevent this issue.
