vagrant: update vagrant image to buster from jessie I honestly have no idea if this works since I don't use vagrant, but looking around online suggests it should work fine. Differential Revision: https://phab.mercurial-scm.org/D7309

packaging: remove references to debian jessie Jessie is on life support at this point, so let's update the list of releases in the Makefiles. Differential Revision: https://phab.mercurial-scm.org/D7308

sqlitestore: remove superfluous r-prefixes on strings I did this file separately because it's a _ton_ of hits and it had some manual reformatting fallout as a result of black squeezing some expressions onto a single line. Differential Revision: https://phab.mercurial-scm.org/D7307

cleanup: remove pointless r-prefixes on single-quoted strings This is the promised second step on single-quoted strings. These had existed because our source transformer didn't turn r'' into b'', so we had tagged some strings as r-strings to get "native" strings on both Pythons. Now that the transformer is gone, we can dispense with this nonsense. Methodology: I ran hg locate 'set:added() or modified() or clean()' | egrep '.*\.py$' | xargs egrep --color=never -n -- \[\^b\]\[\^a-z\]r\'\[\^\'\\\\\]\*\'\[\^\'\ in an emacs grep-mode buffer, and then used a keyboard macro to iterate over the results and remove the r prefix as needed. # skip-blame removing unneeded r prefixes left over from Python 3 migration.

rust-threads: force Rayon to respect the worker count in config As per the inline comment, this is a workaround because Rust code does not yet know how to read config files. Differential Revision: https://phab.mercurial-scm.org/D7310

phabricator: use context manager form of progress in uploadchunks Follow-up to 453079605242 / D7046. Differential Revision: https://phab.mercurial-scm.org/D7134

cleanup: remove pointless r-prefixes on double-quoted strings This is only double-quoted strings. I'll do single-quoted strings as a second step. These had existed because our source transformer didn't turn r"" into b"", so we had tagged some strings as r-strings to get "native" strings on both Pythons. Now that the transformer is gone, we can dispense with this nonsense. Methodology: I ran hg locate 'set:added() or modified() or clean()' | egrep '.*\.py$' | xargs egrep --color=never -n -- \[\^a-z\]r\"\[\^\"\\\\\]\*\"\[\^\"\] in an emacs grep-mode buffer, and then used a keyboard macro to iterate over the results and remove the r prefix as needed. # skip-blame removing unneeded r prefixes left over from Python 3 migration.

formatting: remove another data-ogre from the config example The fix extension will pass the contents on stdin and read the output from stdout. By invoking `rustfmt` as `rustfmt {rootpath}`, we tell rustfmt to format the given path and update it on disk. That also makes rustftm not produce the formatted output to stdout. So the fix extension ends up writing out empty files. Differential Revision: https://phab.mercurial-scm.org/D7304
