(cherry picked from commit 423e77d6de497931585d1883805a9e3fa4096b0b) * bpo-40204: Fix Sphinx sytanx in howto/instrumentation.rst (GH-21858) Use generic '.. object::' to declare markers, rather than abusing '.. c:function::' which fails on Sphinx 3. (cherry picked from commit 43577c01a2ab49122db696e9eaec6cb31d11cc81) * bpo-40204: Fix duplicates in the documentation (GH-21857) Fix two Sphinx 3 issues: Doc/c-api/buffer.rst:304: WARNING: Duplicate C declaration, also defined in 'c-api/buffer'. Declaration is 'PyBUF_ND'. Doc/c-api/unicode.rst:1603: WARNING: Duplicate C declaration, also defined in 'c-api/unicode'.

(cherry picked from commit 46d10b1237c67ff8347f533eda6a5468d098f7eb) * bpo-40204: Add :noindex: in the documentation (GH-21859) Add :noindex: to duplicated documentation to fix "duplicate object description" errors. For example, fix this Sphinx 3 issue: Doc/library/configparser.rst:1146: WARNING: duplicate object description of configparser.ConfigParser.optionxform, other instance in library/configparser, use :noindex: for one of them (cherry picked from commit d3ded080482beae578faa704b13534a62d066f9f) * bpo-40204, doc: Fix syntax of C variables (GH-21846) For example, fix the following Sphinx 3 errors: Doc/c-api/buffer.rst:102: WARNING: Error in declarator or parameters Invalid C declaration: Expected identifier in nested name.

Simply remove names in this case, since names are not shown anyway. For example, fix the Sphinx 3 warning: Doc/reference/introduction.rst:96: duplicate token description of *:name, other instance in reference/expressions (cherry picked from commit 1abeda80f760134b4233608e2c288790f955b95a)

| | | | | | | | | | | | (GH-21474) GH-msg373510 [bpo-32528]()/GH-13528 changed `asyncio.CancelledError` such that it no longer inherits from `concurrent.futures.CancelledError`. As this affects existing code, specifically when catching the latter instead of the former in exception handling, it should be documented in the "What's new in 3.8?" document.

| | | | | | | | | | | * bpo-40630: Add tracemalloc.reset_peak (GH-20102, cherrypick 8b62644) The reset_peak function sets the peak memory size to the current size, representing a resetting of that metric.

| | | | | | | | | | | Try to make the meaning of platlibdir clear. The previous wording could be misinterpreted to suggest that it will be used to find all shared libraries on the system, and not just Python extensions. Furthermore, it was unclear whether it affects third-party (site-packages) extensions or not. The new wording tries to make its dual purpose clear, and provide the additional example of extensions in site-packages.

* bpo-24416: Return named tuple from date.isocalendar() (GH-20113)Paul Ganssle2020-05-161-0/+7
| | | | | | | | | | | | | | | | | | | | | | | {date, datetime}.isocalendar() now return a private custom named tuple object IsoCalendarDate rather than a simple tuple. In order to leave IsocalendarDate as a private class and to improve what backwards compatibility is offered for pickling the result of a datetime.isocalendar() call, add a __reduce__ method to the named tuples that reduces them to plain tuples. (This is the part of this PR most likely to cause problems — if it causes major issues, switching to a strucseq or equivalent would be prudent). The pure python implementation of IsoCalendarDate uses positional-only arguments, since it is private and only constructed by position anyway; the equivalent change in the argument clinic on the C side would require us to move the forward declaration of the type above the clinic import for whatever reason, so it seems preferable to hold off on that for now. bpo-24416: https://bugs.python.org/issue24416 Original PR by Dong-hee Na with only minor alterations by Paul Ganssle.

| | | | | | | | | | | | | Optimize the subprocess module on FreeBSD using closefrom(). A single close(fd) syscall is cheap, but when sysconf(_SC_OPEN_MAX) is high, the loop calling close(fd) on each file descriptor can take several milliseconds. The workaround on FreeBSD to improve performance was to load and mount the fdescfs kernel module, but this is not enabled by default.
