[PATCH db-tools 2/2] Add osinfo-db-export tool for packing an osinfo database archive

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a new osinfo-db-export tool which creates an archive in the
tar (pax) format, with XZ compression and can filling it with the
database files from one of the standard libosinfo database locations,
or a custom directory.

This makes it easy for users to create their own local custom database
content and then distribute and import it on many machines. It will
also be used for creating official release archives of the libosinfo
database from upstream.

 $ osinfo-db-export --verbose  osinfo-db-2016-06-15.tar.xz

+=head1 NAME
+
+osinfo-db-export - Export to a osinfo database archive
+
+=head1 SYNOPSIS
+
+osinfo-db-export [OPTIONS...] ARCHIVE-FILE
+
+=head1 DESCRIPTION
+
+The B<osinfo-db-export> tool will create an osinfo database
+archive file containing the content from one of the standard
+local database locations:
+
+=over 1
+
+=item B<system>
+
+This is the primary system-wide database location, intended
+for use by operating system vendors distributing database
+files in the native package format.
+
+=item B<local>
+
+This is the secondary system-wide database location, intended
+for use by system administrators wishing to provide an updated
+database for all users.
+
+=item B<user>
+
+This is the user private database location, intended for use
+by unprivileged local users wishing to provide applications
+they use with an updated database.
+
+=back
+
+If run by a privileged account (ie root), the B<local> database
+location will be used by default, otherwise the B<user> location
+will be used.
+
+=head1 OPTIONS
+
+=over 8
+
+=item B<--user>
+
+Override the default behaviour to force archiving files from the
+B<user> database location.
+
+=item B<--local>
+
+Override the default behaviour to force archiving files from the
+B<local> database location.
+
+=item B<--system>
+
+Override the default behaviour to force archiving files from the
+B<system> database location.
+
+=item B<--dir=PATH>
+
+Override the default behaviour to force archiving files from the
+custom directory B<PATH>.
+
+=item B<--root=PATH>
+
+Prefix the database location with the root directory given by
+C<PATH>. This is useful when wishing to archive files that are
+in a chroot environment or equivalent.
+
+=item B<--version=VERSION>
+
+Set the version string for the files in the archive to
+B<VERSION>. If this argument is not given, the version
+will be set to the current date in the format B<YYYY-MM-DD>.
+
+=item B<-v>, B<--verbose>
+
+Display verbose progress information when archiving files
+
+=back
+
+=head1 EXIT STATUS
+
+The exit status will be 0 if all files were packed
+successfully, or 1 if at least one file could not be
+packed into the archive.
