| | | | Since 2f3941d743481ac48628b8b2c075f2b82762050b this function returns the response string, rather than nothing.
* gh-95782: Fix io.BufferedReader.tell() etc. being able to return offsets < 0 ↵6t8k2024-02-174-3/+62
| | | | | | | | | | | | | | | | | | | | (GH-99709) lseek() always returns 0 for character pseudo-devices like `/dev/urandom` (for other non-regular files, e.g. `/dev/stdin`, it always returns -1, to which CPython reacts by raising appropriate exceptions). They are thus technically seekable despite not having seek semantics. When calling read() on e.g. an instance of `io.BufferedReader` that wraps such a file, `BufferedReader` reads ahead, filling its buffer, creating a discrepancy between the number of bytes read and the internal `tell()` always returning 0, which previously resulted in e.g. `BufferedReader.tell()` or `BufferedReader.seek()` being able to return positions < 0 even though these are supposed to be always >= 0. Invariably keep the return value non-negative by returning max(former_return_value, 0) instead, and add some corresponding tests.

| | | | | ListSeparator should not be encoded. This could happen when a long line pushes its separator to the next line, which would have been encoded.
* gh-100985: Consistently wrap IPv6 IP address during CONNECT (GH-100986)Derek Higgins2024-02-174-5/+29

* gh-115103: Implement delayed memory reclamation (QSBR) (#115180)Sam Gross2024-02-1618-2/+577
| | | | | | This adds a safe memory reclamation scheme based on FreeBSD's "GUS" and quiescent state based reclamation (QSBR). The API provides a mechanism for callers to detect when it is safe to free memory that may be concurrently accessed by readers.
* gh-115556: Remove quotes from command-line arguments in test.bat and rt.bat ↵Łukasz Langa2024-02-163-21/+29
| | | | | | | | | | | | (#115557) This change essentially replaces usage of `%1` with `%~1`, which removes quotes, if any. Without this change, the if statements fail due to the quotes mangling the syntax. Additionally, this change works around comma being treated as a parameter delimiter in test.bat by escaping commas at time of parsing. Tested combinations of rt and regrtest arguments, all seems to work as before but now you can specify commas in arguments like "-uall,extralargefile".

* gh-114271: Make `thread._rlock` thread-safe in free-threaded builds (#115102)mpage2024-02-165-10/+68
| | | | | | | | | The ID of the owning thread (`rlock_owner`) may be accessed by multiple threads without holding the underlying lock; relaxed atomics are used in place of the previous loads/stores. The number of times that the lock has been acquired (`rlock_count`) is only ever accessed by the thread that holds the lock; we do not need to use atomics to access it.

* gh-112529: Make the GC scheduling thread-safe (#114880)Sam Gross2024-02-167-16/+71
| | | | | | | | | | The GC keeps track of the number of allocations (less deallocations) since the last GC. This buffers the count in thread-local state and uses atomic operations to modify the per-interpreter count. The thread-local buffering avoids contention on shared state. A consequence is that the GC scheduling is not as precise, so "test_sneaky_frame_object" is skipped because it requires that the GC be run exactly after allocating a frame object.

See https://github.com/openssl/openssl/pull/23224 for details. Instead, use X509_STORE_get1_objects, newly added in that PR. X509_STORE_get1_objects does not exist in current OpenSSLs, but we can polyfill it with X509_STORE_lock and X509_STORE_unlock. * Work around const-correctness problem * Add missing X509_STORE_get1_objects failure check * Add blurb

* gh-115490: Work around test.support.interpreters.channels not handling ↵T. Wouters2024-02-151-2/+7
| | | | | | | | | | unloading (#115515) Work around test.support.interpreters.channels not handling unloading, which regrtest does when running tests sequentially, by explicitly skipping the unloading of test.support.interpreters and its submodules. This can be rolled back once test.support.interpreters.channels supports unloading, if we are keeping sequential runs in the same process around.
