I am not sure if the "never going to work" claim is a correct one. The "no hardcoded default in the variable, read command line, fill missing ones from the two config files and finally apply the default for the ones that are still missing" was cumbersome, error-prone without a table, but did work. It seems that no matter how we cut it, the cumbersomeness has to exist, as long as the command line --identity needs to be taken care of. Without that complication, I really liked the base series---the "set var to hardcoded default, overwrite with config and then overwrite with command line, without having to check if we already got value in an earlier step" was so much simpler and easy to explain X-<. > @@ -371,17 +380,30 @@ sub read_config { > ... > my $help; > my $git_completion_helper; > -my $rc = GetOptions("h" => \$help, > - "dump-aliases" => \$dump_aliases); > ... > @@ -410,8 +432,6 @@ sub read_config { > ... > "smtp-auth=s" => \$smtp_auth, > - "no-smtp-auth" => sub {$smtp_auth = 'none'}, > - "identity=s" => \$identity, You seem to be building on top of ab/send-email-transferencoding-fix and something else, and these two hunks did not apply. I think I managed to wiggle the patch in correctly, though. Thanks.

Fix a regression in my recent 3494dfd3ee ("send-email: do defaults -> config -> getopt in that order", 2019-05-09). I missed that the $identity variable needs to be extracted from the command-line before we do the config reading, as it determines which config variable we should read first. See [1] for the report. The sendemail.identity feature was added back in 34cc60ce2b ("send-email: Add support for SSL and SMTP-AUTH", 2007-09-03), there were no tests to assert that it worked properly. So let's fix both the regression, and add some tests to assert that this is being parsed properly. While I'm at it I'm adding a --no-identity option to go with --[to|cc|bcc] variable, since the semantics are similar. It's like to/cc/bcc except that unlike those we don't support multiple identities, but we could now easily add it support for it if anyone cares. In just fixing the --identity command-line parsing bug I discovered that a narrow fix to that wouldn't do. In read_config() we had a state machine that would only set config values if they weren't set already, and thus by proxy we wouldn't e.g. set "to" based on sendemail.to if we'd seen sendemail.gmail.to before, with --identity=gmail. I'd modified some of the relevant code in 3494dfd3ee, but just reverting to that wouldn't do, since it would bring back the regression fixed in that commit. Refactor read_config() do what we actually mean here. We don't want to set a given sendemail.VAR if a sendemail.$identity.VAR previously set it. The old code was conflating this desire with the hardcoded defaults for these variables, and as discussed in 3494dfd3ee that was never going to work. Instead pass along the state of whether an identity config set something before, as distinguished from the state of the default just being false, or the default being a non-bool or true (e.g. --transferencoding). I'm still not happy with the test coverage here, e.g. there's nothing testing sendemail.smtpEncryption, but I only have so much time to fix this code. 1. https://public-inbox.org/git/5cddeb61.1c69fb81.47ed4.e648@mx.google.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> --- Documentation/git-send-email.txt | 4 ++ git-send-email.perl | 60 ++++++++++++++++++++---------- t/t9001-send-email.sh | 64 ++++++++++++++++++++++++++++++++ 3 files changed, 108 insertions(+), 20 deletions(-)
