rebase: while rewriting desc hashes, ignore ambiguous prefix "hashes" If a repo is sufficiently large, a six digit number "hash prefix" can somewhat easily reference an ambiguous hash prefix. Differential Revision: https://phab.mercurial-scm.org/D12552

tests: add test demonstrating issue with ambiguous has prefixes during rebase Differential Revision: https://phab.mercurial-scm.org/D12551

test: accept another error message on lack of TLS client certificate Differential Revision: https://phab.mercurial-scm.org/D12492

sslutil: support TLSV1_ALERT_PROTOCOL_VERSION reason code It looks like python 3.10 returns a different reason code on protocol version mismatch. Differential Revision: https://phab.mercurial-scm.org/D12491

test: override default cipher selection when connecting to TLS 1.0/1.1 servers The default set of ciphers on python 3.10 is incompatible with old TLS versions. Differential Revision: https://phab.mercurial-scm.org/D12490

sslutil: be less strict about which ciphers are allowed when using --insecure Python 3.10 restricted which ciphers are enabled by default, leading to no available ciphers for TLS < 1.2. When using the --insecure flag we allow old TLS, so also adjust the cipher list to give connections a chance to work. On the server side, also loosen the cipher selection in tests (when using the devel.serverexactprotocol option). Differential Revision: https://phab.mercurial-scm.org/D12489

sslutil: avoid deprecation warnings from python 3.10's ssl module Use ssl.PROTOCOL_TLS_{CLIENT,SERVER} and SSLContext.{min,max}imum_version when supported (3.7+). And, catch deprecation warnings when the user asks for deprecated TLS versions (1.0 and 1.1). Differential Revision: https://phab.mercurial-scm.org/D12488

zeroconf: fix deprecation warning with python 3.10 threading.condition.notifyAll → threading.condition.notify_all Differential Revision: https://phab.mercurial-scm.org/D12487

test: deal with changed error message on python 3.10 Differential Revision: https://phab.mercurial-scm.org/D12493

mail: don't complain about a multi-word email.method I want to be able to set email.method to "ssh relay /usr/sbin/sendmail" without needing an extra trivial shell script. This works fine since we pass the full command to a shell, except for validateconfig trying to find it in $PATH. Differential Revision: https://phab.mercurial-scm.org/D7542

help: set the large-file-limit to 10MB This is a minor increase (5%) and makes the doc much clearer. Differential Revision: https://phab.mercurial-scm.org/D12484

help: clarify the unit of `ui.large-file-limit` config Its might be a bit confusing, especially since `large-file.min-size` uses MB. Differential Revision: https://phab.mercurial-scm.org/D12483

debuglock: ignore ENOENT error when unlocking This is consistent with the main `lock.release` code. Differential Revision: https://phab.mercurial-scm.org/D12481

run-tests: introduce "forward-slash" version of everything on windows This should be useful for some shell invocation. Differential Revision: https://phab.mercurial-scm.org/D12480
