Koji 1.18.0 Release notes¶
Migrating from Koji 1.17¶
For details on migrating see Migrating to Koji 1.18
Security Fixes¶
Client Changes¶
Add option for custom cert location
The CLI now has an option for setting a custom SSL certificate, similar to the options for Kerberos authentication.
Load client plugins from ~/.koji/plugins
This change allows users to load their own cli plugins from ~/.koji/plugins
or from another location by using the plugin_paths setting.
Show load/capacity in list-channels
The list-channels display has been expanded to show overall totals for load
and capacity.
Allow taginfo cli to use tag IDs
The taginfo command can now accept a numeric tag id on the command line.
Add option to show channels in list-hosts
The list-hosts command will now display channel subscriptions if the
--show-channels option is given.
Remove merge option from edit-external-repo
This option was mistakenly added to the command and never did anything. It is gone now.
Honor mock.package_manager tag setting in mock-config cli
The mock-config command will now honor this setting just as kojid does.
Library Changes¶
New multicall interface
This feature implements a new and much better way to use multicall in the Koji library. These changes create a new implementation outside of ClientSession. The old way will still work.
With this new implementation:
a multicall is tracked as an instance of MultiCallSession
the original session is unaffected
multiple multicalls can be managed in parallel, if desired
MultiCallSession behaves more or less like a session in multicall mode
method calls return a VirtualCall instance that can later be used to access the result
MultiCallSession can be used as a context manager, ensuring that the calls are executed
Usage examples can be found in the Writing Koji Code document.
Web UI Changes¶
Retain old search pattern in web ui
The search results page of the web ui now retains a search form with the current search pre-filled. This makes it easier for users to refine their searches.
Display task durations in webui
The taskinfo page in the web ui now shows task durations in addition to
timestamps.
Builder Changes¶
Rebuild SRPMS before building
For rpm builds from an uploaded srpm, Koji will now rebuild the srpm in the build environment first. This ensures that the NVR is correct for the resulting build.
The old behavior can be requested by setting rebuild_srpm=False in the tag
extra data for the build tag in question.
User createrepo_c by default
The use_createrepo_c configuration option for kojid now defaults to True.
Use createrepo update option even for first repo run
If there is no older repo for a tag, Koji will now attempt to find
a related repo to use createrepo --update with.
This will speed up first-time repo generations for tags that
predominantly inherit their content from another build tag.
Scale task_avail_delay based on bin rank
This is an adjustment to Koji’s decentralized scheduling algorithm. It should result in better utilization of host capacity, particularly when a channel has hosts that are very heterogeneous in capacity.
The meaning of the task_avail_delay setting is different now.
Within a channel-arch bin, the hosts with highest capacity will take the task
immediately, while hosts lower down will have a delay proportional to their
rank.
The “rank” here is a float between 0.0 and 1.0 used as a multiplier.
So task_avail_delay is the maximum time that any host will wait to
take a task.
Hosts with higher available capacity will be more likely to claim a task, resulting in better utilization of the highest capacity hosts.
Use RawConfigParser for kojid
The use of percent signs is common in kojid.conf because of the
host_principal_format setting.
This causes an error in python3 if SafeConfigParser is used, so we use
RawConfigParser instead.
Handle bare merge mode
This feature adds a new merge mode for external repos named bare.
This mode is intended for use with modularity.
Use of this mode requires createrepo_c version 0.14.0 or later on the builders that handle the createrepo tasks.
System Changes¶
API for reserving NVRs for content generators
This feature allows content generators to reserve NVRs earlier in the build
process similar to builds performed by kojid. The NVR is reserved by
calling CGInitBuild() and finalized by the CGImport() call.
Per-tag configuration of rpm macros
This feature allows setting rpm macros via the tag extra field. These macros
will be added to the mock configuration for the buildroot. The system
looks for extra values of the form rpm.macro.NAME.
For example, to set the dist tag for a given tag, you could use a command like:
$ koji edit-tag f30-build -x rpm.macro.dist=MYDISTTAG
Per-tag configuration for module_hotfixes setting
Koji now handles the field mock.yum.module_hotfixes in the tag extra.
When set, kojid will set module_hotfixes=0/1 in the yum portion of the
mock configuration for a buildroot.
Allow users to opt out of notifications
This feature lets users opt out of notifications that they would otherwise automatically recieve, such as build and tag notifications for:
the build owner (the user who submitted the build)
the package owner within the given tag
These opt-outs are user controlled and can be managed with the new
block-notification and unblock-notificiation commands.
Allow hub policy to match version and release
This feature adds new policy tests to match version and release.
This tests are glob pattern matches.
Allow hub policy to match build type
Koji added btypes in version 1.11 along with content generators. Now, all builds have one or more btypes.
This change allows policies to check the btype value using the buildtype test.
More granular admin permissions
A number of actions that were previously admin-only are now governed by separate permissions:
hostThis permission governs most host management operations, such as adding, editing, enabling/disabling, and restarting.
tagThis permission governs adding, editing, and deleting tags.
targetThis permission governs adding, editing, and deleting targets.
Koji administrators may want to consider reducing the number of users with
full admin permission.
Option to generate separate source repo
The (non-dist) yum repos that Koji generates for building normally don’t include srpms. An old option allowed them to be included in some cases, but they were simply added to each repo. Newer options have been added that instruct Koji to include them as a separate src repo.
In the cli, the regen-repo command now accepts a --separate-source
option that triggers this behavior.
In kojira, the separate_source_tags option is a list of tag patterns.
Build tags that match any of these patterns will have their repos generated
with a separate src repo.
Add volume option for dist-repo
Dist repos can now be generated on volumes other than the main one.
Use the --volume option to the dist-repo command to do so.
Generally you want the repo to be on the same volume as the rpms it will contain. Dist repos hard link (same volume) or copy (different volume) their rpms into place. Using the appropriate volume can drastically improve the efficiency, both in generation time and space consumption.
Minor gc optimizations
This change speeds up portions of garbage collection by making the
build_references check lazy by default.
Rollback errors in multiCall
If one of the calls in a multicall raises an error, then the transaction will be rolled back to the start of that call before Koji proceeds to the next call. This matches the behavior of normal calls more closely.
Multicalls are still handled within single database transaction.
Support tilde in search
The tilde character is no longer prohibited in search terms.
Remove ‘keepalive’ option
The keepalive setting is no longer used anywhere in koji.
It has been removed.
