* gh-127076: Disable strace tests under LD_PRELOAD (#127086)Cody Maloney2024-11-211-0/+1
| | | | | | | | Distribution tooling (ex. sandbox on Gentoo and fakeroot on Debian) uses LD_PRELOAD to intercept system calls and potentially modify them when building. These tools can change the set of system calls, so disable system call testing under these cases. Co-authored-by: Michał Górny <mgorny@gentoo.org>

* gh-97514: Authenticate the forkserver control socket. (GH-99309)Gregory P. Smith2024-11-201-0/+10
| | | | | | | | | | | | | | | | | | | This adds authentication to the forkserver control socket. In the past only filesystem permissions protected this socket from code injection into the forkserver process by limiting access to the same UID, which didn't exist when Linux abstract namespace sockets were used (see issue) meaning that any process in the same system network namespace could inject code. We've since stopped using abstract namespace sockets by default, but protecting our control sockets regardless of type is a good idea. This reuses the HMAC based shared key auth already used by `multiprocessing.connection` sockets for other purposes. Doing this is useful so that filesystem permissions are not relied upon and trust isn't implied by default between all processes running as the same UID with access to the unix socket. ### pyperformance benchmarks No significant changes. Including `concurrent_imap` which exercises `multiprocessing.Pool.imap` in that suite. ### Microbenchmarks This does _slightly_ slow down forkserver use. How much so appears to depend on the platform. Modern platforms and simple platforms are less impacted. This PR adds additional IPC round trips to the control socket to tell forkserver to spawn a new process. Systems with potentially high latency IPC are naturally impacted more. Typically a 1-4% slowdown on a very targeted process creation microbenchmark, with a worst case overloaded system slowdown of 20%. No evidence that these slowdowns appear in practical sense. See the PR for details.

* GH-85168: Use filesystem encoding when converting to/from `file` URIs (#126852)Barney Gale2024-11-191-0/+4
| | | | | | | | Adjust `urllib.request.url2pathname()` and `pathname2url()` to use the filesystem encoding when quoting and unquoting file URIs, rather than forcing use of UTF-8. No changes are needed in the `nturl2path` module because Windows always uses UTF-8, per PEP 529.

* gh-124452: Fix header mismatches when folding/unfolding with email message ↵RanKKI2024-11-161-0/+4
| | | | | | | | | | | | | | | | | | (#125919) The header-folder of the new email API has a long standing known buglet where if the first token is longer than max_line_length, it puts that token on the next line. It turns out there is also a *parsing* bug when parsing such a header: the space prefixing that first, non-empty line gets preserved and tacked on to the start of the header value, which is not the expected behavior per the RFCs. The bug arises from the fact that the parser assumed that there would be at least one token on the line with the header, which is going to be true for probably every email producer other than the python email library with its folding buglet. Clearly, though, this is a case that needs to be handled correctly. The fix is simple: strip the blanks off the start of the whole value, not just the first physical line of the value.

* gh-126554: ctypes: Correctly handle NULL dlsym values (GH-126555)George Alexopoulos2024-11-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | For dlsym(), a return value of NULL does not necessarily indicate an error [1]. Therefore, to avoid using stale (or NULL) dlerror() values, we must: 1. clear the previous error state by calling dlerror() 2. call dlsym() 3. call dlerror() If the return value of dlerror() is not NULL, an error occured. In ctypes we choose to treat a NULL return value from dlsym() as a "not found" error. This is the same as the fallback message we use on Windows, Cygwin or when getting/formatting the error reason fails.

| | | | | | | | | | | | | | | | definitions. (GH-126808) Fixes a bug where pygettext would attempt to extract a message from a code like this: def _(x): pass This is because pygettext only looks at one token at a time and '_(x)' looks like a function call. However, since 'x' is not a string literal, it would erroneously issue a warning.

| | | | | | | | | | | | | | | | | | * gh-71936: Fix race condition in multiprocessing.Pool Proxes of shared objects register a Finalizer in BaseProxy._incref(), and it will call BaseProxy._decref() when it is GCed. This may cause a race condition with Pool(maxtasksperchild=None) on Windows. A connection would be closed and raised TypeError when a GC occurs between _ConnectionBase._check_writable() and _ConnectionBase._send_bytes() in _ConnectionBase.send() in the second or later task, and a new object is allocated that shares the id() of a previously deleted one. Instead of using the id() of the token (or the proxy), use a unique, non-reusable number. Co-Authored-By: Akinori Hattori <hattya@gmail.com>
