The utility for building of AlmaLinux distributions (repos, ISO images).
3349585d78
Multithreading was added to parallelize the computation of image checksums. Resulting memory structures are protected via synchronization primitives. Max number of threads is uncapped- experiments were done to determine whether a maximum number of threads would yield greater efficiency and there were no gains from this. Likewise, experiments were done to determine whether pools of threads computed in separate processes could likewise decrease compute-time. Evidence did not suggest that this was the case. This indicate that the checksum operation is bounded by I/O read/write times. Merges: https://pagure.io/pungi/pull-request/1520 Jira: RHELCMP-5967 Signed-off-by: James Kunstle jkunstle@redhat.com |

Pungi
Pungi is a distribution compose tool.
Composes are release snapshots that contain release deliverables such as:
- installation trees
- RPMs
- repodata
- comps
- (bootable) ISOs
- kickstart trees
- anaconda images
- images for PXE boot
Tool overview
Pungi consists of multiple separate executables backed by a common library.
The main entry-point is the pungi-koji
script. It loads the compose
configuration and kicks off the process. Composing itself is done in phases.
Each phase is responsible for generating some artifacts on disk and updating
the compose
object that is threaded through all the phases.
Pungi itself does not actually do that much. Most of the actual work is delegated to separate executables. Pungi just makes sure that all the commands are invoked in the appropriate order and with correct arguments. It also moves the artifacts to correct locations.
