DESCRIPTION

55       An importer and remover for public-inboxes which takes
56       "PublicInbox::Eml" or Email::MIME messages as input and stores them in
57       a git repository as documented in
58       <https://public-inbox.org/public-inbox-v1-format.txt>, except it does
59       not allow duplicate Message-IDs.
60
61       It requires git(1) and git-fast-import(1) to be installed.
62

METHODS

64   new
65               my $im = PublicInbox::Import->new($git, @committer);
66
67       Initialize a new PublicInbox::Import object.
68
69   add
70               my $parsed = PublicInbox::Eml->new($message);
71               $im->add($parsed);
72
73       Adds a message to to the git repository.  This will acquire
74       "$GIT_DIR/ssoma.lock" and start git-fast-import(1) if necessary.
75
76       Messages added will not be visible to other processes until "done" is
77       called, but "remove" may be called on them.
78
79   remove
80               my $junk = PublicInbox::Eml->new($message);
81               my ($code, $orig) = $im->remove($junk);
82
83       Removes a message from the repository.  On success, it returns a
84       ':'-prefixed numeric code representing the git-fast-import mark and the
85       original messages as a PublicInbox::Eml (or Email::MIME) object.  If
86       the message could not be found, the code is "MISSING" and the original
87       message is undef.  If there is a mismatch where the "Message-ID" is
88       matched but the subject and body do not match, the returned code is
89       "MISMATCH" and the conflicting message is returned as orig.
90
91   done
92       Finalizes the git-fast-import(1) and unlocks the repository.  Calling
93       this is required to finalize changes to a repository.
