* [3.10] bpo-44630: Fix assertion errors in csv module (GH-27127) (GH-27129)Miss Islington (bot)2021-07-131-4/+8
| | | | | | | | | | | | | | | | | | | Fix incorrect handling of exceptions when interpreting dialect objects in the csv module. Not clearing exceptions between calls to PyObject_GetAttrString() causes assertion failures in pydebug mode (or with assertions enabled). Add a minimal test that would've caught this (passing None as dialect, or any object that isn't a csv.Dialect subclass, which the csv module allows and caters to, even though it is not documented.) In pydebug mode, the test triggers the assertion failure in the old code. Contributed-By: T. Wouters [Google] (cherry picked from commit 0093876328afa330224c9d887c18dee0b3117852) Co-authored-by: T.

* bpo-41486: zlib uses an UINT32_MAX sliding window for the output buffer ↵Miss Islington (bot)2021-07-051-30/+114
| | | | | | | | | | | | | | | | | | | (GH-26143) * zlib uses an UINT32_MAX sliding window for the output buffer These funtions have an initial output buffer size parameter: - zlib.decompress(data, /, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE) - zlib.Decompress.flush([length]) If the initial size > UINT32_MAX, use an UINT32_MAX sliding window, instead of clamping to UINT32_MAX. Speed up when (the initial size == the actual size). This fixes a memory consumption and copying performance regression in earlier 3.10 beta releases if someone used an output buffer larger than 4GiB with zlib.decompress. Reviewed-by: Gregory P.

* bpo-44434: Don't call PyThread_exit_thread() explicitly (GH-26758) (GH-26824)Miss Islington (bot)2021-06-211-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | _thread.start_new_thread() no longer calls PyThread_exit_thread() explicitly at the thread exit, the call was redundant. On Linux with the glibc, pthread_cancel() loads dynamically the libgcc_s.so.1 library. dlopen() can fail if there is no more available file descriptor to open the file. In this case, the process aborts with the error message: "libgcc_s.so.1 must be installed for pthread_cancel to work" pthread_cancel() unwinds back to the thread's wrapping function that calls the thread entry point. The unwind function is dynamically loaded from the libgcc_s library since it is tightly coupled to the C compiler (GCC). The unwinder depends on DWARF, the compiler generates DWARF, so the unwinder belongs to the compiler. Thanks Florian Weimer and Carlos O'Donell for their help on investigating this issue.
