# 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

## Pulp RPM Plugin Use Cases
### MVP
##### Sync
- Basic Sync
<!-- end list -->
- As an authenticated user, I can sync a remote yum/dnf repository
<!-- end list -->
- RPM \[#3202\]
- SRPM \[#3202\]
- Erratum \[#3202\]
<!-- end list -->
- Sync types
<!-- end list -->
- 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. \[provided by pulpcore\]
<!-- end list -->
- Download Behaviors
<!-- end list -->
- 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.
<!-- end list -->
- RPM \[#3204\]
- SRPM \[#3204\]
- Erratum \[#3204\]
<!-- end list -->
- 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
<!-- end list -->
- As an authenticated user, I can sync a remote yum/dnf repository
<!-- end list -->
- DRPM
- Distribution (kickstart tree)
- Comps.xml content types (package group, environment, category, langpacks)
- Yum repo metadata file
- Modules
<!-- end list -->
- Sync behaviors
<!-- end list -->
- 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. \[provided by pulpcore [3415](https://pulp.plan.io/issues/3415)\]
- 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
<!-- end list -->
- Performance features
<!-- end list -->
- 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.
<!-- end list -->
- 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
<!-- end list -->
- Sync types
<!-- end list -->
- As a user, I can sync a kickstart tree from the same feed as other rpm/yum/dnf content.
<!-- end list -->
- Download Behaviors
<!-- end list -->
- 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. <span style="color:red;">Note: We may move this into the MVP if it is ready in core early enough.</span>
- As a user, I can specify the number of retries to be done before failing a given download
<!-- end list -->
- Checksum Features
<!-- end list -->
- As a user, I can sync a repository and have the files' checksums validated to ensure that no content is corrupt.
<!-- end list -->
- GPG Signature Features
<!-- end list -->
- 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.
<!-- end list -->
- Mirror List Support
<!-- end list -->
- As a plugin writer I can configure mirror lists and rotate between the mirrors
<!-- end list -->
- round robin support
- nearest mirror support (GeoIP or ping times)
##### Publish
- As an authenticated user, I can publish a yum/dnf repository.
<!-- end list -->
- DRPM
- Distribution (kickstart tree)
- Comps.xml content types (package group, environment, category, langpacks)
- Yum repo metadata file
- Modules
<!-- end list -->
- 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.
<!-- end list -->
- 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.
<!-- end list -->
- As a user, I can have publish skip one or more content types, e.g. drpm, errata, etc
<!-- end list -->
- We can't think of a use case for this. Maybe export of only RPMs and Errata, see export use case.
