| description | Read this before authoring, editing, or reviewing a *.comp.toml file; do not work from memory. Explains the azldev component definition format and review workflow, covering component structure, spec sources, build config, release calculation, render options, file organization, overlay hygiene, stale files, disabled tests, and testing verification. Triggers include comp.toml, component config, review component, component hygiene, spec source, upstream-distro, build defines, release calculation, includes. |
Component definition files (*.comp.toml)
A component definition tells azldev where a package's spec comes from and how to
customize it for your distro. Every component lives under [components.<name>].

Structure
A bare entry inherits everything from your distro's defaults — most upstream packages
need nothing more:
[components.curl]
Add sub-tables only for what you change. The fields you will reach for most:
| Field | Purpose |
|---|
spec | where the spec comes from (see below) |
overlays / overlay-files | targeted spec/source edits (see the azldev-overlays skill) |
build.defines / build.with / build.without | RPM macro and bcond build tweaks |
release.calculation | how the Release tag is managed |
render.skip-file-filter | rendering edge-case escape hatch |
Spec source
The spec field selects where the spec is fetched from. When omitted, the component
inherits the distro default (normally an upstream import).
[components.curl]
[components.curl]
spec = { type = "upstream", upstream-distro = { name = "fedora", version = "rawhide" } }
[components.mydistro-rpm-config]
spec = { type = "upstream", upstream-name = "redhat-rpm-config" }
[components.mydistro-release]
spec = { type = "local", path = "mydistro-release.spec" }
Build configuration
[components.mypackage.build]
defines = { rhel = "11" }
with = ["feature_x"]
without = ["plugin_rhsm"]
Release calculation
release.calculation controls the Release: tag. There are four modes:
auto (default) — auto-detect whether the spec uses %autorelease or a static
release and handle it accordingly. Correct for most packages.
autorelease — force %autorelease handling (use when auto-detection misreads a
spec that wraps %autorelease in a conditional).
static — force static-integer handling and bump the integer on render (the
inverse of autorelease).
manual — you own the Release: value. Use this only when render fails with a
"non-standard Release tag" error. A manual component is not bumped by the
render/commit/amend cycle, so increment its release yourself in the same change
(see the azldev-update-component skill).
[components.mypackage.release]
calculation = "manual"
Render configuration
render.skip-file-filter = true keeps all source and patch files during render.
azldev normally prunes files not referenced by the rendered spec; set this only for
the rare spec whose Source/Patch filenames use macros the filter cannot expand.
File organization
- Inline — put simple, customization-free components directly in a shared config
file (e.g.
[components.jq]).
- Dedicated — give a component its own
<name>/<name>.comp.toml once it needs
overlays, build config, or a local spec. Rule of thumb: anything more than
[components.<name>] earns a dedicated file.
- A parent config picks up dedicated files through an
includes glob, for example
includes = ["**/*.comp.toml"].
Review checklist
Start with azldev comp list -p <name> -q -O json, then use
azldev comp query -p <name> -q -O json when the review needs parsed spec details.
For a change review, focus on the diff while checking enough surrounding context to
ensure it fits the component and repository conventions.
- Organization: The component follows the repository's inline-versus-dedicated-file
convention; its name matches upstream or sets
spec.upstream-name; no stale or
orphaned component files remain.
- Spec source: The default upstream source is preferred. Pins explain why they are
needed, and local specs are used only when overlays cannot express the change.
- Overlays: Every overlay explains why it exists. Prefer structured overlay types
over regex; scope unavoidable
spec-search-replace expressions by section and, when
applicable, package, and use TOML literal strings. spec-search-replace cannot span
lines. Remove overlays that upstream has made unnecessary. See the azldev-overlays skill.
- Build config: Defines and bcond overrides are necessary and correspond to the
spec. If
build.check.skip = true, require a specific build.check.skip_reason and
verify that fixing the tests is impractical; skipped %check is a last resort.
- Release mode:
auto is the default. Force autorelease or static only when
auto-detection is wrong. Use manual only for a non-standard release tag, and verify
the component increments its release itself.
- Generated state: The lock matches the final component inputs, and rendered output
contains the intended changes without unrelated drift.
- Testing: Changes that can affect RPM output were built and smoke-tested in a mock
chroot. Organization, comment, or documentation-only metadata edits do not require a
rebuild when the resolved component inputs are unchanged.
Report findings by severity: errors for correctness or required-policy violations,
warnings for maintainability risks, and info for optional improvements. Prefer small,
actionable fixes over unrelated cleanup.
Documenting changes
Add a TOML comment explaining why a non-obvious field is set (a version pin, a
workaround), and link the upstream commit or bug when the change is based on one. For
overlays, use the overlay metadata table instead (see the azldev-overlays skill).
