extensions: avoid a crash when the version isn't properly byteified on py3 We already force bytestr on the `testedwith` and `buglink` attributes in dispatch.py when generating a bug report with a similar comment about not every extension being ported to py3. We should do the same here, so the function can be properly typed. Differential Revision: https://phab.mercurial-scm.org/D9433

ui: ensure `getpass()` returns bytes Previously, this could return either bytes or str. I'm not sure which direction we should go in, but since the input is bytes, I guess bytes makes sense as output. `debuguigetpass` crashed because it assumed bytes would be returned, `sslcontext.load_cert_chain()` is happy with bytes or str if the type info in PyCharm is correct, and `smtplib.SMTP.login()` wants str. I couldn't figure out how to test this, because the test stalls for input with `echo test | hg debuguigetpass --config ui.interactive=1`, likely because it drains stdin before prompting. The custom input reading with `ui.nontty=1` does not. I'm also a bit concerned with all of this encoding/decoding. The existing code in the mail module uses `encoding.strfromlocal()`, but the username and password are ascii encoded/decoded in `mercurial.url.passwordmgr.find_user_password()` with `pycompat.{str,bytes}url()`. I'm not sure if this inconsistency could cause subtle compatability issues. Differential Revision: https://phab.mercurial-scm.org/D9375

packaging: regenerate the Windows requirements manifest on Windows SecretStorage is a Linux package, and the other stuff removed is a dependency of it. I assume this was last generated on Linux, and noticed this trying to add another package and regenerating on Windows. Differential Revision: https://phab.mercurial-scm.org/D9404

pyoxidizer: point to the py3 requirements instead of py2 on Windows Differential Revision: https://phab.mercurial-scm.org/D9406

extensions: gracefully warn when doing min version check with no local version After doing a `make clean`, I started getting cryptic failures to import extensions with the `minimumhgversion` attribute on py3: *** failed to import extension evolve: '>' not supported between instances of 'int' and 'NoneType' *** failed to import extension topic: '>' not supported between instances of 'int' and 'NoneType' This now handles the `(None, None)` tuple before comparing, and disables the extension with the same friendly message as in py2.

diff: do not concatenate immutable bytes while building a/b bodies (issue6445) Use bytearray instead. I don't know what's changed since Python 2, but bytes concatenation is 100x slow on Python 3. % python2.7 -m timeit -s "s = b''" "for i in range(10000): s += b'line'" 1000 loops, best of 3: 321 usec per loop % python3.9 -m timeit -s "s = b''" "for i in range(10000): s += b'line'" 5 loops, best of 5: 39.2 msec per loop Benchmark using tailwind.css (measuring the fast path, a is empty): % HGRCPATH=/dev/null python2.7 ./hg log -R /tmp/issue6445 -p --time \ --color=always --config diff.word-diff=true >/dev/null (prev) time: real 1.580 secs (user 1.560+0.000 sys 0.020+0.000) (this) time: real 1.610 secs (user 1.570+0.000 sys 0.030+0.000) % HGRCPATH=/dev/null python3.9 ./hg log -R /tmp/issue6445 -p --time \ --color=always --config diff.word-diff=true >/dev/null (prev) time: real 114.500 secs (user 114.460+0.000 sys 0.030+0.000) (this) time: real 2.180 secs (user 2.140+0.000 sys 0.040+0.000) Benchmark using random tabular text data (not the fast path): % dd if=/dev/urandom bs=1k count=1000 | hexdump -v -e '16/1 "%3u," "\n"' > ttf % hg ci -ma % dd if=/dev/urandom bs=1k count=1000 | hexdump -v -e '16/1 "%3u," "\n"' > ttf % hg ci -mb % HGRCPATH=/dev/null python2.7 ./hg log -R /tmp/issue6445 -p --time \ --color=always --config diff.word-diff=true >/dev/null (prev) time: real 3.240 secs (user 3.040+0.000 sys 0.200+0.000 (this) time: real 3.230 secs (user 3.070+0.000 sys 0.160+0.000) % HGRCPATH=/dev/null python3.9 ./hg log -R /tmp/issue6445 -p --time \ --color=always --config diff.word-diff=true >/dev/null (prev) time: real 44.130 secs (user 43.850+0.000 sys 0.270+0.000) (this) time: real 4.170 secs (user 3.850+0.000 sys 0.310+0.000)

procutil: use rapply(tonativestr, ...) to preserve lists when they come in This was broken when script was a list instead of a string.

chg: reset errno prior to calling strtol() Otherwise we can't figure out if the last strtol() invocation failed or not.

chg: do not close dir fd while iterating It works so long as the dp is the last entry, but readdir(dp) would fail with EBADF. Let's not do that and close the dir fd explicitly.

chg: show debug message for each fd to be closed It helps debugging. The number of file descriptors should be small in most cases, so the console output wouldn't get bloated even with CHG_DEBUG=1.

chg: apply clang-format

chg: close file descriptors when starting the daemon It's good practice to close file descriptors when forking to start a daemon. This did not appear to happen yet, which results in flock hanging in one location in our system (because the chg daemon keeps the locked file open).

crecord: render chunkpad on Windows (issue6427) When using Windows wrappers of PDCurses (e.g., windows-curses), the chunkpad does not render when executing `hg commit -i`. This is due to attempting to refresh one too many columns of the pad. Differential Revision: https://phab.mercurial-scm.org/D9267
