Subject: [PATCH v5 00/13] send-email: various optimizations to speed up by >2x
Date: Fri, 28 May 2021 11:23:39 +0200 [thread overview]
Message-ID: <cover-00.13-00000000000-20210528T092228Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-00.13-00000000000-20210524T074932Z-avarab@gmail.com>
Hopefully the final iteration. Updates a commit message to explain why
I moved away from File::Spec::Functions, rebases on master, and
explains and deals with the "undef in config" issue Jeff King noted.
Ævar Arnfjörð Bjarmason (13):
send-email tests: support GIT_TEST_PERL_FATAL_WARNINGS=true
send-email tests: test for boolean variables without a value
send-email: remove non-working support for "sendemail.smtpssl"
send-email: refactor sendemail.smtpencryption config parsing
send-email: copy "config_regxp" into git-send-email.perl
send-email: lazily load config for a big speedup
send-email: lazily shell out to "git var"
send-email: use function syntax instead of barewords
send-email: get rid of indirect object syntax
send-email: lazily load modules for a big speedup
perl: lazily load some common Git.pm setup code
send-email: move trivial config handling to Perl
perl: nano-optimize by replacing Cwd::cwd() with Cwd::getcwd()

to run t9001-send-email.sh, down from ~20s.
+ Changing File::Spec::Functions::{catdir,catfile} to invoking class
+ methods on File::Spec itself is idiomatic. See [1] for a more
+ elaborate explanation, the resulting code behaves the same way, just
+ without the now-pointless function wrapper.

@@ Commit message
"undef" or "" case (true and false, respectively), let's just punt on
those and others and have "git config --type=bool" handle it.
+ The "grep { defined } @values" here covers a rather subtle case. For
+ list values such as sendemail.to it is possible as with any other
+ config key to provide a plain "-c sendemail.to", i.e. to set the key
+ as a boolean true. In that case the Git::config() API will return an
+ empty string, but this new parser will correctly return "undef".
+
+ However, that means we can end up with "undef" in the middle of a
+ list. E.g. for sendemail.smtpserveroption in conjuction with
+ sendemail.smtpserver as a path this would have produce a warning. For
+ most of the other keys we'd behave the same despite the subtle change
+ in the value, e.g. sendemail.to would behave the same because
+ Mail::Address->parse() happens to return an empty list if fed
+ "undef". For the boolean values we were already prepared to handle
+ these variables being initialized as undef anyway.
+
This brings the runtime of "git send-email" from ~60-~70ms to a very
steady ~40ms on my test box. We now run just one "git config"
invocation on startup instead of 8, the exact number will differ based
