An importer and remover for public-inboxes which takes "PublicInbox::Eml" or Email::MIME messages as input and stores them in a git repository as documented in <>, except it does not allow duplicate Message-IDs.

It requires git(1) and git-fast-import(1) to be installed.



        my $im = PublicInbox::Import->new($git, @committer);

Initialize a new PublicInbox::Import object.


        my $parsed = PublicInbox::Eml->new($message);

Adds a message to to the git repository. This will acquire "$GIT_DIR/ssoma.lock" and start git-fast-import(1) if necessary.

Messages added will not be visible to other processes until "done" is called, but "remove" may be called on them.


        my $junk = PublicInbox::Eml->new($message);
        my ($code, $orig) = $im->remove($junk);

Removes a message from the repository. On success, it returns a ':'-prefixed numeric code representing the git-fast-import mark and the original messages as a PublicInbox::Eml (or Email::MIME) object. If the message could not be found, the code is "MISSING" and the original message is undef. If there is a mismatch where the "Message-ID" is matched but the subject and body do not match, the returned code is "MISMATCH" and the conflicting message is returned as orig.


Finalizes the git-fast-import(1) and unlocks the repository. Calling this is required to finalize changes to a repository.
