"git fetch" wrapper for v2 inbox mirrors

Synopsis

public-inbox-fetch [--exit-code] -C INBOX_DIR

Description

public-inbox-fetch updates git storage of public-inbox mirrors. With v2 inboxes, it allows detection of new epochs and avoids unnecessary traffic on old epochs.

public-inbox-fetch does not use nor require any configuration files of its own.

It does not run public-inbox-index(1), making it suitable for maintaining git-only backups.

For v2 inboxes, it will maintain $INBOX_DIR/manifest.js.gz file to speed up future invocations.  It always safe to remove manifest.js.gz, it is merely an optimization and will be restored on the next invocation.

To prevent fetches on any v2 epoch, use chmod(1) to remove write permissions to the top-level of the epoch.  For example, to disable fetches on epoch 4:

        chmod a-w $INBOX_DIR/git/4.git

If you wish to re-enable fetches to the epoch:

        chmod u+w $INBOX_DIR/git/4.git

Options

-q
--quiet

Quiets down progress messages, also passed to git-fetch(1).

-T REMOTE
--try-remote REMOTE

Try a given remote name instead of origin or _grokmirror. May be specified more than once.

Default: origin, _grokmirror

--exit-code

Exit with 127 if no updates are done.  This can be used in shell scripts to avoid invoking public-inbox-index(1) when there are no updates:

        public-inbox-fetch -q --exit-code && public-inbox-index
        test $? -eq 0 || exit $?
-v
--verbose

Increases verbosity, also passed to git-fetch(1).

--torsocks=auto|no|yes
--no-torsocks

Whether to wrap git(1) and curl(1) commands with torsocks(1).

Default: auto

Exit Codes

127

no updates when “--exit-code” is used above

public-inbox-fetch will also exit with curl “EXIT CODES” in curl(1) as documented in the curl(1) manpage (e.g. 7 when curl cannot reach a host).  Likewise, git-fetch(1) failures are also propagated to the user.
