bpo-45386: Handle strftime's ValueError graciously in xmlrpc.client (GH-28765) (GH-28934)

2021-10-13T17:59:45+00:00

At import time, the xmlrpc.client module uses different date formats to
test strftime so it can format years with 4 digits consistently.
Depending on the underlying C library and its strftime implementation
some of these calls can result in ValueErrors, blocking the
xmlrpc.client module from being imported.

This commit changes the behavior of this bit of code to react to
ValueError exceptions, treating the format that caused them as an
non-viable option.

[docs] lexical_analysis: Expand the text on ``_`` (GH-28903) (GH-28933)

2021-10-13T16:58:06+00:00

Also:
* Expand the discussion into its own entry. (Even before this,
  text on ``_`` was longet than the text on ``_*``.)

* Briefly note the other common convention for `_`: naming unused
  variables.

bpo-45453: Fix test_embed.StdPrinterTests (GH-28916) (GH-28917)

2021-10-13T10:24:47+00:00

test_embed.StdPrinterTests now always use the file descriptor 1 for
stdout, rather than using sys.__stdout__.fileno().
PyFile_NewStdPrinter() does crash if the argument is not 1 or 2.

Fix also a few pyflakes warnings: remove unused import and variables.
