Greetings, In today's pkg team discussion, the topics of staged publishing and repository deployment came up.
Here's my proposed solution: Staged Publishing ================= Staged publishing being defined as the ability to publish packages to a repository without packages from a given publishing "session" being added to the catalog until explicitly instructed. Right now, if clients retrieve a new catalog from a repository as a new OpenSolaris release is being published, they may inadvertently attempt to upgrade to a release that hasn't yet had all of its packages published causing errors. Changing the publishing step so that packages added during a "publishing session" are not added to the "current" catalog, until instructed, would allow a repository to remain available during publishing without negatively impacting clients in the aforementioned way. To implement this, the depot server needs to be changed to support two publishing modes: immediate and staged. - Immediate publishing mode would add packages to the catalog and updatelog as they are published (matches existing behaviour) and would be the default. - Staged publishing mode would add packages to a special temporary catalog and updatelog file until the depot is instructed to "commit" whatever packages have been published so far. Once the depot is instructed to "commit" these packages, it will add the contents of the temporary catalog and updatelog files to the current catalog and updatelog (repo_dir/catalog/). It will then create a copy of the current catalog and updatelog and place them into repo_dir/catalogs/ISO8601DATE/. Staged Deployment ================= Staged deployment being defined as the ability to serve multiple versions of the catalog. This would require changing the depot server to allow the administrator to provide a date representative of a catalog snapshot (repo_dir/catalogs/ISO8601DATE/) to serve instead of serving the current catalog data (repo_dir/catalog/). Storing the current catalog in repo_dir/catalog allows backwards compatibility with our existing depot versions allowing staged deployment/publishing catalog support to simply be ignored by older depot versions. -- Shawn Walker _______________________________________________ pkg-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/pkg-discuss
