Fake Koji

Fake Koji serves as a storage for builds along with logs and source snapshots.

Naming Convention

Fake Koji uses Koji's NVRA (name, version, release, architecture):

• name represents java product (java-10-openjdk, java-11-openjdk)
• version represents tag (jdk.10.46, jdk.11.23)
• release represents:
  • repository i.e. (shenandoah, ember)
  • number of changesets since last tag
  • keywords (static, slowdebug, fastdebug, zero, openj9)
• architecture can be:
  • src containing source snapshot
  • real platform (x86_64, i686, aarch64, win10_x64, rhel7_aarch64, fedora28_x64, centos7_i386)
• data stores build log for each architecture and pull/incoming logs for src

SCP Upload

Default port: 9822

Supported cases for NVRA

Upload

scp ./dir/file user@host:nvra

scp ./dir/nvra user@host

scp ./dir/nvra user@host:/any_path/differentNvra

scp .dir/nvra user@host:/any_path/nvra

The uploaded file will be stored in user@host:/path_to_builds/n/v/r/a/. Note that in the last two cases the any_path, where the NVRA should be stored, is ignored.

Download:

scp user@host:nvra ./dir/

scp user@host:nvra ./dir/differentNvra

The downloaded file: ./dir/nvra.

Multiple upload and download

Works similarly:

scp ./dir/nvra1 ./dir/nvra2 user@host

scp user@host:nvra1 user@host:nvra2 ./dir

Supported cases for logs

Upload

scp ./dir/logFile user@host:nvra/log

scp ./dir/logFile user@host:nvra/log/newFile

The logFile will be stored in user@host:/path_to_builds/n/v/r/data/logs/a/

Download

scp user@host:nvra/log/logFile ./dir

scp user@host:nvra/log/logFile ./dir/newLogFile

The downloaded file: ./dir/logFile

Multiple upload and download

Works the same as single upload/download:

scp logFile1 logFile2 user@host:nvra/log

scp user@host:nvra1/log/logFile1 user@host:nvra2/log/logFile2 ./dir

Recursive upload

Having nvra1 and nvra2 in ./dir, then

scp -r ./dir user@host

will upload nvras to user@host:/path_to_builds/n1/v1/r1/a1 and user@host:/path_to_builds/n2/v2/r2/a2, respectively.

Having logFile1 and logFile2 in ./dir, then

scp -r ./dir user@host:nvra/logs

will upload both log files to user@host:/path_to_builds/n/v/r/data/logs/a/.

Having data1 and data2 in ./dir, then

scp -r ./dir user@host:nvra/data

will upload both files to user@host:/path_to_builds/n/v/r/data/

Recursive download

NVRA:

Recursive download of nvra works same as normal download. Multiple tarballs for one nvra is unlikely to be supported.

Logs:

scp -r user@host:nvra/logs ./dir

will download all logs for given nvra.

scp -r user@host:nvra/data/logs ./dir

and

scp -r user@host:nvra/data ./dir

are currently broken.

XML-RPC API

Default port: 9848

Part of Fake Koji is xml-rpc server compatible with Koji and Brew. You can get build information using these methods:

• getPackageId
  • parameter: package name
  • returns the package id if given package
• ListBuilds
  • parameter: package id
  • returns all builds of given package
• listTags
  • parameter: build id
  • returns tags of given build
  • tags tell us whether build is done on a cetain architecture or not
• listRPMs
  • parameter: build id, architectures
  • returns all build's rpms of given architectures
• listArchives
  • parameter: build id, architectures
  • archives represent .tar.gz, .zip and .msi files
  • returns build's archives of given architectures

Curl API

You can get various information about Fake Koji's configuration and storage using its curl api.

Basic usage:

curl host/get?option:argument

Alternatively you can use url bar in your browser.

Options:

• allProducts
  • lists all available products
• allProjects
  • lists all available projects
• dport
  • download port
• expectedArchesOfNvr
  • returns list of architectures the nvra is supposed to be built on
  • argument: nvra (java-10-openjdk-jdk.10.46-0.static.x86_64)
• expectedArchesOfProject
  • returns list of architectures the project is supposed to be built on
  • argument: project (java-10-openjdk-updates)
• productOfNvra
  • returns product of given nvra
  • argument: nvra
• productOfProject
  • returns product of given project
  • argument: project
• projectOfNvra
  • returns project of given nvra
  • argument: nvra
• projectsOfProduct
  • list of projects of given product
  • argument: product (java-10-openjdk)
• repos
  • path to folder containing repositories
• root
  • path to folder containing builds
• uport
  • scp upload port
• viewlport
  • view port
• xport
  • XML-RPC port

HTTP File Listing

Default port: 9849

Here you can browse Fake Koji's folder structure. There are three sections with same content but different sorting. The first one uses version sorting(last version on top), the second uses latest modified sorting(the latest modified file on top) and the last one uses latest modified directory content.

Folder structure

└── name
    └── version
        └── release
            ├── arch1
            │   └── name-version-release-arch1.tar.gz
            ├── arch2
            │   └── name-version-release-arch2.tar.gz
            ├── arch3
            │   └── name-version-release-arch3.tar.gz
            ├── data
            │   └── logs
            │       ├── arch1
            │       ├── arch2
            │       ├── arch3
            │       └── src
            └── src
                └── name-version-release-src.tar.gz

HTTP View

Default port: 80

This is the frontend of fake Koji. Here you can see the latest successful builds of every project. Projects are divided by their product. To see all builds of a project by clicking on project's details.

Jenkins SCM Koji Plugin

Next to Fake Koji there is Jenkins plugin, which ensures cooperation between Jenkins and Fake Koji. Based on configuration, plugin provides builds. -Dhudson.remoting.ClassFilter=hudson.plugins.scm.koji.model.Build,hudson.plugins.scm.koji.model.RPM,hudson.plugins.scm.koji.model.BuildProvider may be still necessary to add to jenkins start up.

Configuration

• Koji top URLs
  • URL of Kojihub, Brewhub or Fake Koji
  • this is the URL of xml-rpc server, from which plugin gets builds' information
  • can contain more than URLs separated by space, first URL found first served
• Koji download URLs
  • RPMs or archives get downloaded from these URLs
  • can contain multiple URLs separated by space, first URL found first served
• Package name
  • package name to watch
  • can contain multiple names separated by space
• Package arch
  • only builds for specified arch will be used
  • can be empty
  • can contain multiple archs separated by coma
• Package tag
  • only builds containing specified tag
  • may be empty to match all the builds
  • supports glob pattern
• Excluding NVRs
  • glob patterns for NVRs not to download.
  • example: {*debug*, *src*}
• Download directory
  • name of directory inside Jenkins' workspace to download RPMs/archives
  • if empty, the RPMs/archives will be downloaded directly into workspace
• Max previous builds
  • max number of previous builds to check, in case there's more of them
• Clean download directory
  • removes all the content of the download directory before the download
• Create subdirectory for each NVR
  • creates subdirectiory under the download directory where the name of subdirectory is going to be the name of the NVR of the RPM package

Configuration examples

Results package

After Jenkins jobs is finished, the plugin generates a page with results information. This page shows what specific build was used(name, version, release, NVR, tags), what RPMs or archives were downloaded, links and hash sums to this build can be also found here. If available, sources of build are included.

Future goals

• Project/Repository management
• Implementation of HTTPS
• JSON API
• New frontend (Angular app)
