Pulp RPM Roadmap¶

This is a living document that is moving towards a long term plan to develop RPM plugin for Pulp 3.0 and beyond.

Supported Content Types¶

MVP¶

• RPM [#3199]
• SRPM [#3199]
• Erratum [#3201]

Post-MVP¶

• DRPM
• Distribution (kickstart tree)
• Comps.xml content types (package group, environment, category, langpacks)
• Yum repo metadata file
• Modules

Pulp RPM Plugin Use Cases¶

MVP¶

Sync¶

• Basic Sync

• As an authenticated user, I can sync a remote yum/dnf repository

• RPM [#3202]
• SRPM [#3202]
• Erratum [#3202]

• Sync types

• As a user, I can exactly mirror the content of a remote repository. [provided by pulpcore]
• As a user, I can mirror the content of a remote repository with an additive behavior, so content is never removed locally. [provided by pulpcore]

• Download Behaviors

• As a user, my sync task does not fail just because one download failed. [provided by pulpcore?]

Publish¶

• As an authenticated user, I can publish a yum/dnf repository.

• RPM [#3204]
• SRPM [#3204]
• Erratum [#3204]

• As a user, I can specify relative path at which a repository will be served. [provided by pulpcore]
• As a user, I can configure if a repository will be served over an SSL or a non-SSL connection. [provided by pulpcore]
• As user, I can sync from a yum/dnf repo published by Pulp. [should be taken into account for any publish story]

Post-MVP¶

Sync¶

• Basic Sync

• As an authenticated user, I can sync a remote yum/dnf repository

• DRPM
• Distribution (kickstart tree)
• Comps.xml content types (package group, environment, category, langpacks)
• Yum repo metadata file
• Modules

• Sync behaviors

• As a user, I can mirror only the most recent X versions that correspond to a particular rpm name.
• As a user, I can force a full re-sync of a remote repository
• As a user, I can sync from a mirrorlist feed.
• As a user, I can sync from a metalink URL to avoid a replay attack from a malicious mirror. [provided by pulpcore 3415]
• As a user, I can sync only signed packages (RPM/DRPM/SRPM)
• As a user, I can have sync skip one or more content types, e.g. drpm, errata, etc

• Performance features

• As a user, my sync will skip most of its work if the repomd.xml revision number has not changed is equal to or older (lower) than the previously successfully synced one.

• As a user, my sync is not skipped if it's a first sync
• As a user, my sync is not skipped if the importer configuration has changed since the last sync
• As a user, my sync is not skipped if any content has been removed from the repository since the last sync
• As a user, downloading of content starts quickly

• Sync types

• As a user, I can sync a kickstart tree from the same feed as other rpm/yum/dnf content.

• Download Behaviors

• As a user, I can limit the maximum speed of downloading in bytes / sec
• As a user, I can limit the number of concurrent downloads
• As a user, I can sync content on-demand by setting a repository's download policy.
• As a user, I can specify the number of retries to be done before failing a given download

• Checksum Features

• As a user, I can sync a repository and have the files' checksums validated to ensure that no content is corrupt.

• GPG Signature Features

• As a user, I can verify that repo metadata has a valid signature. (would be a new feature)
• As a user, I can specify a set of trusted GPG keys. Any packages that are not signed with one of these keys is not synced.

• Mirror List Support

• As a plugin writer I can configure mirror lists and rotate between the mirrors

• round robin support
• nearest mirror support (GeoIP or ping times)

Publish¶

• As an authenticated user, I can publish a yum/dnf repository.

• DRPM
• Distribution (kickstart tree)
• Comps.xml content types (package group, environment, category, langpacks)
• Yum repo metadata file
• Modules

• As a user, I can publish a repository incrementally (re-use the pre-existing metadata and only add additional units)
• As a user, I can force a full republish of a repository.
• As a user, my publish will skip most of its work if no changes to a repository were made since last publish.
• As a user, I can configure which checksum algorithm to use when creating metadata.
• As a user, I can configure which checksum algorithm to use when creating updateinfo.xml.
• Special publish for modules [TBD]

Export¶

• As a user, I can export a repository or group of repositories to an ISO file (ISO 9660)
• As a user, I can export a repository or group of repositories to a DVD / Blueray file (UDF aka. ISO/IEC 13346)
• As a user, I can export a repository to a specified directory
• As a user, I can export a repositories content that is associated or updated (errata) since a specific datetime( aka incremental?)
• As a user, I can export RPM packages and errata as a set of JSON files

Upload¶

• As an authenticated user, I can upload yum/dnf content types (not including Distribution)
• As an authenticated user, I can upload a comps.xml file and have it parsed into its constituent content units (requires knowledge of the destination repo at creation time)

Copy¶

• As a user, I can copy a content of a specific type from one repository to another repository
• As a user, I can copy RPM packages and all their dependencies from one repository to another repository
• As a user, I can copy an Erratum and all the RPM packages it references from one repository to another repository
• As a user, I can copy an Erratum and all the RPM packages it references and all the RPM dependencies from one repository to another repository
• Some content types create a new content unit in the destination repo instead of just copying.
• Special copy for modules [TBD]

Not much yet discussed use cases¶

Content Protection¶

• As an authenticated user, I can use key based authentication to allow/disallow access to content served by the content app
• As an authenticated user, I can use user/password based authentication to allow/disallow access to content served by the content app.

Applicability¶

• As an authenticated user, I can trigger an applicability for a consumer.
• As an authenticated user, I can trigger an applicability for a repository.

Rsync Distributor¶

• As a user i can distribute rpm content using a remote server.

Pulp 2 features not present in Pulp 3¶

• "gpgkey" importer setting - only used by pulp-agent.
• "generate_sqlite" - sqlite files are only used by yum as an optimization. DNF does not use them and has no plans to. Performance gains marginal.

• they are also used by the "repoview" feature which we will also leave out of 3.0. Making browseable publications will hopefully be solved in the core.

• As a user, I can have publish skip one or more content types, e.g. drpm, errata, etc

• We can't think of a use case for this. Maybe export of only RPMs and Errata, see export use case.
