This is technically a backwards-incompatible behavior change, and therefore would be safer to make opt-in. However, the damage resulting from reporting the situation too eagerly is expected to be trivial, while the damage resulting from callers failing to opt-in (which is obviously the status quo, and is likely to persist in most cases) is potentially at least somewhat serious. For interactive calls from the command line, interactive cancellation is arguably not really an error, but a human user will be able to interpret the somewhat unusual exit code in light of their immediately preceding interactions just fine. Signed-off-by: Oswald Buddenhagen --- v4: - add tests (which also cover the partial confirmation behavior in the first place) - add docu - rework commit message again v3: - use a tally instead of flags after all, as my seemingly simple idea apparently requires lots of thinking to grasp fully - correct exit code when zero messages are to be sent. this cannot actually happen, as it induces an exit via usage() earlier on. - unfold nested ternary to save junio's sanity (who proved his point by unfolding it slightly incorrectly) - expand commit message v2: - fix do_quit() not resetting $sent_all Cc: Junio C Hamano Cc: Phillip Wood --- Documentation/git-send-email.txt | 9 ++++++++ git-send-email.perl | 32 ++++++++++++++++++++++++---- t/t9001-send-email.sh | 36 ++++++++++++++++++++++++++++++++ 3 files changed, 73 insertions(+), 4 deletions(-) diff --git a/Documentation/git-send-email.txt b/Documentation/git-send-email.txt index 492a82323d..d6ce3a0bd9 100644 --- a/Documentation/git-send-email.txt +++ b/Documentation/git-send-email.txt @@ -480,6 +480,15 @@ include::includes/cmd-config-section-all.txt[] include::config/sendemail.txt[] + +EXIT STATUS +----------- + +Zero is returned when all specified patches were sent, while one is returned +when an error occurs. 10 is returned if the user interactively skips sending +some patches, and 11 if they skip all patches. + + EXAMPLES -------- Use gmail as the smtp server diff --git a/git-send-email.perl b/git-send-email.perl index affbb88509..cd4db84b7f 100755 --- a/git-send-email.perl +++ b/git-send-email.perl @@ -256,6 +256,26 @@ sub system_or_die { die $msg if $msg; } +my $sent_files = 0; + +sub do_exit { + if ($sent_files == @files) { + # All specified messages were sent + exit(0); + } elsif ($sent_files) { + # At least some messages were sent + exit(10); + } else { + # User cancelled on first message already + exit(11); + } +} + +sub do_quit { + cleanup_compose_files(); + do_exit(); +} + sub do_edit { if (!defined($editor)) { $editor = Git::command_oneline('var', 'GIT_EDITOR'); @@ -1195,8 +1215,7 @@ sub validate_address { if (/^d/i) { return undef; } elsif (/^q/i) { - cleanup_compose_files(); - exit(0); + do_quit(); } $address = ask("$to_whom ", default => "", @@ -1619,8 +1638,7 @@ sub send_message { } elsif (/^e/i) { return -1; } elsif (/^q/i) { - cleanup_compose_files(); - exit(0); + do_quit(); } elsif (/^a/i) { $confirm = 'never'; } @@ -2001,6 +2019,10 @@ sub process_file { return 0; } + if ($message_was_sent) { + $sent_files++; + } + # set up for the next message if ($thread) { if ($message_was_sent && @@ -2278,3 +2300,5 @@ sub body_or_subject_has_nonascii { } return 0; } + +do_exit(); diff --git a/t/t9001-send-email.sh b/t/t9001-send-email.sh index 48bf0af2ee..dce0b1c498 100755 --- a/t/t9001-send-email.sh +++ b/t/t9001-send-email.sh @@ -1187,6 +1187,42 @@ test_expect_success $PREREQ 'confirm does not loop forever' ' $patches ' +test_confirm_many () { + clean_fake_sendmail + GIT_SEND_EMAIL_NOTTY=1 \ + git send-email \ + --confirm=auto \ + --from="Example " \ + --to=nobody@example.com \ + --smtp-server="$(pwd)/fake.sendmail" \ + -2 exit_sts + test_cmp expected_sts exit_sts || return 1 + ls commandline* 2>/dev/null | wc -l > num_mails + test_cmp expected_num num_mails || return 1 +} + +test_expect_success $PREREQ 'interactively skip none' ' + (echo y && echo y) > replies && + echo 0 > expected_sts && + echo 2 > expected_num && + test_confirm_many +' + +test_expect_success $PREREQ 'interactively skip some' ' + (echo n && echo y) > replies && + echo 10 > expected_sts && + echo 1 > expected_num && + test_confirm_many +' + +test_expect_success $PREREQ 'interactively skip all' ' + (echo n && echo n) > replies && + echo 11 > expected_sts && + echo 0 > expected_num && + test_confirm_many +' + test_expect_success $PREREQ 'utf8 Cc is rfc2047 encoded' ' clean_fake_sendmail && rm -fr outdir &&
