From f4dc9432fd287bde9100488943baf3c6a04d90d1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Fri, 28 May 2021 11:23:49 +0200 Subject: send-email: lazily load modules for a big speedup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Optimize the time git-send-email takes to do even the simplest of things (such as serving up "-h") from around ~150ms to ~80ms-~90ms by lazily loading the modules it requires. Before this change Devel::TraceUse would report 99/97 used modules under NO_GETTEXT=[|Y], respectively. Now it's 52/37. It now takes ~15s 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. 1. http://lore.kernel.org/git/8735u8mmj9.fsf@evledraar.gmail.com Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- git-send-email.perl | 71 +++++++++++++++++++++++++++++------------------------ 1 file changed, 39 insertions(+), 32 deletions(-) (limited to 'git-send-email.perl') diff --git a/git-send-email.perl b/git-send-email.perl index cc1027d877..a8949c9d31 100755 --- a/git-send-email.perl +++ b/git-send-email.perl @@ -19,20 +19,10 @@ use 5.008; use strict; use warnings $ENV{GIT_PERL_FATAL_WARNINGS} ? qw(FATAL all) : (); -use POSIX qw/strftime/; -use Term::ReadLine; use Getopt::Long; -use Text::ParseWords; -use Term::ANSIColor; -use File::Temp qw/ tempdir tempfile /; -use File::Spec::Functions qw(catdir catfile); use Git::LoadCPAN::Error qw(:try); -use Cwd qw(abs_path cwd); use Git; use Git::I18N; -use Net::Domain (); -use Net::SMTP (); -use Git::LoadCPAN::Mail::Address; Getopt::Long::Configure qw/ pass_through /; @@ -166,7 +156,6 @@ sub format_2822_time { ); } -my $have_email_valid = eval { require Email::Valid; 1 }; my $smtp; my $auth; my $num_sent = 0; @@ -192,14 +181,6 @@ my (@config_bcc, @getopt_bcc); my $repo = eval { Git->repository() }; my @repo = $repo ?
