bpo-38417: Add umask support to subprocess (GH-16726)

2019-10-12T20:24:56+00:00

On POSIX systems, allow the umask to be set in the child process before we exec.

bpo-6559: Update _posixsubprocess.fork_exec doc (GH-16283)

bpo-36046: Add user and group parameters to subprocess (GH-11950)

2019-09-12T17:15:44+00:00

* subprocess: Add user, group and extra_groups paremeters to subprocess.Popen

This adds a `user` parameter to the Popen constructor that will call
setreuid() in the child before calling exec(). This allows processes
running as root to safely drop privileges before running the subprocess
without having to use a preexec_fn.

This also adds a `group` parameter that will call setregid() in
the child process before calling exec().

Finally an `extra_groups` parameter was added that will call
setgroups() to set the supplimental groups.

bpo-38069: Convert _posixsubprocess to PEP-384 (GH-15780)

2019-09-10T11:01:20+00:00

Summary:
Eliminate uses of `_Py_IDENTIFIER` from `_posixsubprocess`, replacing them with interned strings.

Also tries to find an existing version of the module, which will allow subinterpreters.

bpo-35550: Fix incorrect Solaris define guards (GH-11275)

2018-12-31T02:16:40+00:00

Python source code uses on several places ifdef sun or defined(sun) without the underscores, which is not standard compliant and shouldn't be used.

Defines should check for __sun instead. Reference: http://nadeausoftware.com/articles/2012/01/c_c_tip_how_use_compiler_predefined_macros_detect_operating_system#Solaris

bpo-35214: Add _Py_ prefix to MEMORY_SANITIZER def. (GH-10503)

2018-11-13T06:01:22+00:00

Rename our new MEMORY_SANITIZER define to _Py_MEMORY_SANITIZER.
Project based C Preprocessor namespacing at its finest. :P

bpo-35214: Initial clang MemorySanitizer support (GH-10479)

2018-11-12T20:07:14+00:00

Adds configure flags for msan and ubsan builds to make it easier to enable.
These also encode the detail that address sanitizer and memory sanitizer
should disable pymalloc.

Define MEMORY_SANITIZER when appropriate at build time and adds workarounds
to existing code to mark things as initialized where the sanitizer is otherwise unable to
determine that.  This lets our build succeed under the memory sanitizer.  not all tests
pass without sanitizer failures yet but we're in pretty good shape after this.

bpo-34651: Only allow the main interpreter to fork. (gh-9279)

2018-09-14T21:17:20+00:00

When os.fork() is called (on platforms that support it) all threads but the current one are destroyed in the child process. Consequently we must ensure that all but the associated interpreter are likewise destroyed. The main interpreter is critical for runtime operation, so we must ensure that fork only happens in the main interpreter.
