Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
archive: defer opening the output until a file is matched Before, if no file is matched, an error is thrown, but the archive is created anyway. When using hgweb, an error 500 is returned as the response body already exists when the error is seen. Afterwards, the archive is created before the first match is emitted. If no match is found, no archive is created. This is more consistent behavior as an empty archive is not a representable in all output formats, e.g. tar archives.
