* bpo-41003: Fix test_copyreg when numpy is installed (GH-20935) (GH-20945) ↵Victor Stinner2020-06-171-5/+11
| | | | | | | | | | | | | (GH-20946) Fix test_copyreg when numpy is installed: test.pickletester now saves/restores warnings.filters when importing numpy, to ignore filters installed by numpy. Add the save_restore_warnings_filters() function to the test.support.warnings_helper module. (cherry picked from commit 8362893e3fe083df2ec8bb94c28b1a78383eadbf) (cherry picked from commit b39d41ba1b77f7bc51c4d6f6d0e336693192cb3a)

* Don't skip pickle check_frame_opcodes() (GH-15027)Miss Islington (bot)2019-07-301-1/+0
| | | | | | | This looks like the only place that proto 4 framing gets exercised so leave it as part of the PGO task. (cherry picked from commit eca7ffc61cf925eae5def8c64b05d47f24e60e1f) Co-authored-by: Neil Schemenauer <nas-github@arctrix.com>
* bpo-37707: Exclude expensive unit tests from PGO task (GH-15009) (#15024)Miss Islington (bot)2019-07-301-0/+3
| | | | | | | | Mark some individual tests to skip when --pgo is used. The tests marked increase the PGO task time significantly and likely don't help improve optimization of the final executable.

* bpo-31993: Do not use memoryview when pickle large strings. (#5154)Serhiy Storchaka2018-01-121-30/+30
| | | | | | PyMemoryView_FromMemory() created a memoryview referring to the internal data of the string. When the string is destroyed the memoryview become referring to a freed memory.
* bpo-31993: Do not create frames for large bytes and str objects (#5114)Serhiy Storchaka2018-01-111-8/+9
| | | | | | | when serialize into memory buffer with C pickle implementations. This optimization already is performed when serialize into memory with Python pickle implementations or into a file with both implementations.
* bpo-31993: Do not allocate large temporary buffers in pickle dump. (#4353)Olivier Grisel2018-01-061-13/+118
| | | | | | | | | | | | | | | | | The picklers do no longer allocate temporary memory when dumping large bytes and str objects into a file object. Instead the data is directly streamed into the underlying file object. Previously the C implementation would buffer all content and issue a single call to file.write() at the end of the dump. With protocol 4 this behavior has changed to issue one call to file.write() per frame. The Python pickler with protocol 4 now dumps each frame content as a memoryview to an IOBytes instance that is never reused and the memoryview is no longer released after the call to write. This makes it possible for the file object to delay access to the memoryview of previous frames without forcing any additional memory copy as was already possible with the C pickler.

* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-2/+2
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.
