config.yaml.example

# RelEasy config.yaml — stable infrastructure for ONE project.
#
# Three files make up a project's on-disk footprint:
#
#   1. config.yaml            — this file. Origin, target branch, AI
#                               settings, notifications, pr_policy. Rarely
#                               edited once a project is set up.
#   2. <name>.session.yaml    — per-effort source data: the `features:`
#                               list and `pr_sources:` selectors. Edit this
#                               between runs as your target work changes.
#                               Lives next to config.yaml by default; point
#                               elsewhere with `session_file:` below or
#                               `--session-file` on the CLI.
#   3. <name>.state.yaml      — runtime progress. Managed by RelEasy; lives
#                               in ${XDG_STATE_HOME:-~/.local/state}/releasy/.
#
# `releasy --stateless` (e.g. `address-review --stateless`) loads THIS file
# (overridable with `--config`) but skips the session and state files.

# ── Project identity (required) ─────────────────────────────────────
# Unique slug for this project on this machine. Doubles as the filename
# of the per-project state file and (by default) the session file:
#   state:   ${XDG_STATE_HOME:-~/.local/state}/releasy/<name>.state.yaml
#   session: <dir-of-this-config>/<name>.session.yaml
# Allowed characters: A-Z a-z 0-9 . _ - (1-64 chars). Pick something
# stable like the target branch you are porting onto. Renaming this
# orphans the old state file — use `releasy adopt` to rebind state to a
# moved/renamed config.
name: antalya-26.3

# ── Session file (optional override) ────────────────────────────────
# By default the session file lives at `<config-dir>/<name>.session.yaml`.
# Set this to point somewhere else (absolute or relative to this file's
# directory). The CLI `--session-file <path>` always takes precedence.
# session_file: sessions/antalya-26.3.session.yaml

# ── Push & PR control ───────────────────────────────────────────────
# Push branches to origin and open PRs.
# Default is false — everything stays local until you enable this.
# push: true

# ── Sequential mode ─────────────────────────────────────────────────
# When true, RelEasy processes the merged-time-sorted PR queue one PR
# per `releasy run` / `releasy continue` invocation:
#   1. The first invocation ports the earliest-merged PR, pushes it,
#      opens a rebase PR, and exits.
#   2. You review the PR; once CI is green you approve & merge it
#      manually into target_branch.
#   3. The next `releasy continue` checks GitHub: if the previous
#      rebase PR was merged, it ports the next PR (created from the
#      now-updated target_branch). If not yet merged, it exits with a
#      non-zero status and changes nothing.
#
# Default: false (batch mode — every discovered PR is ported in one go).
# Incompatible with `pr_sources.groups` in the session file (session
# load will fail).
# sequential: false

# ── Conflict handling ───────────────────────────────────────────────
# When a cherry-pick conflicts and the AI resolver is disabled or gives
# up (after exhausting `ai_resolve.max_iterations` build attempts), the
# pipeline:
#   * Singleton PR or first-of-group: aborts the cherry-pick, deletes the
#     local port branch (it has no useful commits), records the entry as
#     "Conflict" in the GitHub Project. No push, no PR.
#   * Group with N>=1 successful prior picks: aborts the failed pick,
#     pushes the branch as-is, opens a DRAFT PR labelled
#     `ai-needs-attention` with a banner explaining what failed, and
#     records "Conflict" in the GitHub Project. Remaining PRs in
#     the group are not attempted.
# Either way the pipeline keeps going with the next unit.

# ── Existing-PR behaviour ───────────────────────────────────────────
# When a PR for the port branch already exists on GitHub:
#   false (default) — leave it exactly as-is. Don't try to create a new
#                     one (avoids GitHub 422s) and don't touch its
#                     title/body/labels. You can still edit the PR
#                     manually on GitHub.
#   true            — reuse the same PR but overwrite its title and body
#                     with what releasy would have set (source-PR refs,
#                     combined group body, ai-resolved prefix, …). Handy
#                     when source PR descriptions changed or you tweaked
#                     the body format and want the rebase PR to reflect
#                     it.
# update_existing_prs: false

# ── Merged-port label (optional) ────────────────────────────────────
# When set, releasy applies this label to the rebase (port) PR once it
# has been merged into target_branch, and strips the same label from
# every source PR the port was cherry-picked from. Useful for marking
# "this PR has been ported into release X" with a single label that
# moves automatically as ports land.
#
# Source-PR cleanup is best-effort and only touches PRs hosted on the
# configured origin — source PRs on a different repo are skipped (RelEasy
# never writes outside origin). The label is auto-created on origin the
# first time a merged port is observed.
#
# Each tracked unit is processed exactly once: a per-feature flag on
# the state file (`merged_label_applied`) prevents re-hitting GitHub on
# every subsequent `releasy run`. Renaming the label here does NOT
# auto-relabel previously-processed units.
#
# Requires push: true to take effect. Unset / empty disables the feature.
# merged_label: port-antalya
# merged_label_color: "8B5CF6"   # 6-hex color used when releasy creates
#                                #   the label on origin (default: purple).

# ── Work directory ──────────────────────────────────────────────────
# Where to clone/find the origin repo for git operations.
# If it points to an existing git repo, it will be reused (no clone).
# If omitted, uses the current working directory.
# Can also be overridden with --work-dir on the CLI.
# work_dir: /path/to/ClickHouse

# ── Session log (optional) ───────────────────────────────────────
# Append a full transcript of the process (stdout and stderr: Rich
# output, ``click`` messages, ``logging`` warnings, tracebacks) to a file
# for post-run analysis. Relative paths resolve against the directory
# that contains this config file.
# log_file: .releasy/releasy.log

# ── Origin (required) ──────────────────────────────────────────────
# The repo you work against. This is the only repo RelEasy tracks
# as a configured remote.
origin:
  remote: https://github.com/Altinity/ClickHouse.git
  remote_name: origin

# ── Project & target branch ────────────────────────────────────────
# Short project identifier — used to name port branches as
#   feature/<base>/<feature-id>
project: antalya

# The base/target branch PRs are opened into. Two ways to set it:
#
#   1. Explicit (recommended): set 'target_branch' here. --onto becomes
#      optional and you don't need a tag-based name derivation.
#
#   2. Derived: leave 'target_branch' unset and pass --onto <ref> on
#      the CLI. The base branch is then '<project>-<version>', where
#      <version> is parsed from --onto (e.g. v26.3.4.234-lts → 26.3,
#      yielding 'antalya-26.3').
#
# The base branch must already exist on origin before running.
target_branch: antalya-26.3

# ── PR policy ──────────────────────────────────────────────────────
# Policy knobs that apply to EVERY discovered unit (by_labels entries,
# explicit include_prs, groups, …). These live here — not in the
# session file — because they're stable infrastructure: what to do
# with branches, when to retry, whether to open PRs. Edit the session
# file to change *what* to port; edit pr_policy to change *how*.
#
# All values shown below are defaults; omit pr_policy entirely to
# accept them all.
#
# pr_policy:
#   if_exists: skip
#     # When the port branch already exists locally AND no rebase PR has
#     # been opened for it yet:
#     # "skip"     (default) — leave the local branch alone; don't re-process.
#     #                        Also: refuse to start if a cherry-pick / merge
#     #                        / rebase is still in progress in the work dir.
#     # "recreate"           — delete the local branch and rebuild from base.
#     #                        Also: if a cherry-pick / merge / rebase is in
#     #                        progress at startup, abort it and start fresh.
#     # "append"             — cherry-pick any declared PRs that aren't on the
#     #                        existing branch onto its tip and update the
#     #                        rebase PR body to match the declared group
#     #                        order. Use when you've added a PR to a group
#     #                        that already shipped through a prior run and
#     #                        you want to top up the existing branch / PR
#     #                        rather than rebuild from scratch.
#     #                        Detection uses the ``Source-PR:`` commit
#     #                        trailers releasy writes; falls back to ``skip``
#     #                        with a warning if the existing commits don't
#     #                        match a prefix of the declared group.
#     #                        Mostly for groups (singletons have one PR, so
#     #                        there's nothing to top up). The remote-already-
#     #                        exists safety lock is bypassed in this mode
#     #                        since appending is the explicit user opt-in.
#     #
#     # ONCE A REBASE PR IS OPEN: if_exists no longer controls whether the
#     # branch is rebuilt — it never is. `releasy run` switches to
#     # merging origin/<base> into the PR branch (the same flow
#     # `releasy refresh` uses): clean merge → leave PR alone, conflict →
#     # AI-resolve and plain push. Pass --merge-target on the CLI to
#     # push a fresh merge commit even on clean merges. The only setting
#     # that still touches an open PR's branch directly is `append`,
#     # which cherry-picks newly declared PRs on top.
#     #
#     # Note: if the branch already exists on the REMOTE without a tracked
#     # rebase PR, it is ALWAYS skipped in "skip"/"recreate" modes (resolve
#     # those manually so you don't clobber someone else's work).
#     # Individual session entries (pr_sources.by_labels[] /
#     # pr_sources.groups[]) can override this default per-entry with
#     # their own if_exists.
#   auto_pr: true
#     # When true (the default), every pushed port branch gets a PR opened
#     # against the base. Set to false to push branches only and open PRs
#     # manually. Requires push: true to have any effect.
#   retry_failed: true
#     # When a PR unit has a `conflict` entry in state from a previous run:
#     #   true (default) — process the unit again on this run, per the
#     #                    unit's `if_exists` value (see above). For units
#     #                    WITHOUT an open rebase PR, retry can rebuild
#     #                    from base (`recreate`), append, or skip per
#     #                    if_exists. For units WITH an open rebase PR,
#     #                    retry routes through merge-target instead —
#     #                    an open PR's history is never blown away.
#     #   false          — leave the conflicted entry exactly as-is; no
#     #                    cherry-pick, no PR side-effects.
#     # CLI flag `--retry-failed / --no-retry-failed` overrides per-invocation.
#   recreate_closed_prs: false
#     # When true, if state has a rebase_pr_url and that GitHub PR is closed
#     # (not merged), allocate `<canonical>-1`, `-2`, … for the port branch
#     # name and cherry-pick + open a fresh PR. Off by default: a closed
#     # rebase PR just leaves the branch skipped on subsequent runs.

# ── PR sources and features ─────────────────────────────────────────
# These live in the session file, not here. Look for
# `<name>.session.yaml` next to this config (or wherever `session_file:`
# above points). The session file is where you edit:
#
#   * `features:` — the static list of feature branches to rebase.
#   * `pr_sources:` — label-based discovery, explicit include/exclude,
#                     author filters, groups, etc.
#
# See the bundled session template for the full reference.

# ── GitHub Project board ────────────────────────────────────────────
# Sync branch status to a GitHub Project v2 board (optional).
# Only active when push: true.
#
# One-time setup:
#   1. Create a GitHub Project (or run: releasy setup-project)
#   2. Copy the project URL below
#   3. Ensure RELEASY_GITHUB_TOKEN has repo + project scopes
#
# Or auto-setup (creates project + Status field):
#   releasy setup-project
#
# Each rebase gets its own view (tab) in the project, named after
# the base branch (e.g. antalya-26.3). Cards are managed automatically.

  github_project: https://github.com/orgs/Altinity/projects/1

# ── AI conflict resolver (Claude) ───────────────────────────────────
# Optional. When enabled, releasy invokes `claude` to resolve cherry-
# pick conflicts, build, and commit. If Claude prints UNRESOLVED or
# BUILD FAILED (after exhausting `max_iterations` build attempts) or
# fails outright, releasy treats the unit as "Conflict" — see
# the "Conflict handling" section above.
#
# ai_resolve:
#   enabled: false
#   command: claude
#   prompt_file: prompts/resolve_conflict.md
#   # Prompt template used by `releasy refresh` when Claude has to
#   # drive a `git merge` to completion (keeping an open rebase PR
#   # current with its target branch). Same placeholder vocabulary as
#   # prompt_file; the difference is the in-progress operation
#   # (merge vs cherry-pick) and how to conclude it.
#   merge_prompt_file: prompts/resolve_merge_conflict.md
#   # Hard cap (passed into the prompt) on how many build attempts
#   # Claude is allowed to make per conflict before giving up.
#   max_iterations: 5
#   timeout_seconds: 7200
#   build_command: cd build && ninja
#   # Label automatically applied to PRs whose conflicts Claude
#   # resolved cleanly.
#   label: ai-resolved
#   label_color: "8B5CF6"
#   # Label applied to DRAFT PRs released by partial-group failures
#   # (singleton failures don't get a PR — the local branch is dropped).
#   needs_attention_label: ai-needs-attention
#   needs_attention_label_color: "D93F0B"
#   # How many times to re-invoke Claude when the Anthropic streaming
#   # API drops the turn with a transient error (idle timeout, overload,
#   # connection reset, …). Each retry is a fresh turn — independent of
#   # `max_iterations`.
#   api_retries: 3
#   api_retry_backoff_seconds: 15

# ── AI changelog entry synthesis (Claude) ────────────────────────────
# Optional. When enabled, multi-PR groups get a single user-facing
# CHANGELOG entry composed by Claude based on the constituent PRs'
# titles + bodies. Singletons (one PR per port branch) ALWAYS reuse
# the source PR's `Changelog entry` verbatim — Claude is never invoked
# in that case, so the singleton flow has zero API cost.
#
# The synthesizer is told to:
#   - drop intermediate fix-ups inside the group (B fixes a bug A
#     introduced earlier in the same group → the user never saw the
#     bug, so it doesn't belong in the changelog),
#   - drop refactors / internal cleanup with no user-visible effect,
#   - keep the entry to one or two terse, imperative-present-tense
#     sentences matching typical CHANGELOG.md tone.
#
# Failures are non-fatal: the per-PR fallback (first-PR-in-group's own
# changelog entry) is used and a warning is logged.
#
# ai_changelog:
#   enabled: false
#   command: claude
#   prompt_file: prompts/synthesize_changelog.md
#   timeout_seconds: 300
#   # Per-PR body trimmed to this many characters before being inlined
#   # into the prompt (keeps payloads bounded for chatty source PRs).
#   max_pr_body_chars: 3000

# ─────────────────────────────────────────────────────────────────────
# REVIEW RESPONSE (`releasy address-review`)
#
# Reads review comments left on a PR and lets the AI make code
# changes addressing the feedback. Off by default because it spends
# Anthropic tokens every call and writes to your PR branch.
#
# Runs in two modes:
#   * Default            — loads this config, takes the project lock,
#                          records timestamps in state for tracked PRs.
#   * `--stateless`      — loads this config, but skips session/state/lock.
#                          CLI flags (--origin / --build-command / ...)
#                          override anything in config.
#
# Every comment is filtered to an explicit allowlist of trusted
# reviewers BEFORE the AI sees it — untrusted commenters cannot smuggle
# instructions into the run. The allowlist here is unioned with
# `--reviewer` on the CLI; if both are empty, the command refuses to
# run.
#
# Linear history is a hard rule: the AI only appends commits (it uses
# `git revert` to retract anything, never amend / rebase / reset).
# RelEasy pushes with plain `git push` at the end.
#
# review_response:
#   trusted_reviewers:
#     - alice
#     - bob
#   # Reply in-thread (with a bot footer) on every comment classified as
#   # non-actionable. Set to false for a silent run that only reports
#   # via the AI's terminal narration. Override per-invocation with
#   # --reply / --no-reply.
#   reply_to_non_addressable: true
#   # Optional: post one extra top-level summary comment on the PR
#   # describing what was done (distinct from per-comment replies).
#   post_summary_comment: false
#   # Advanced overrides — the defaults below are already sensible.

# ─────────────────────────────────────────────────────────────────────
# WORKFLOW
#
# The base branch must already exist on origin. The pipeline then ports
# each discovered PR / feature onto it:
#
#   releasy run --onto v26.3.4.234-lts   # (or just: releasy run, when
#                                        #  target_branch is set above)
#   → creates "feature/antalya-26.3/<id>" for each PR / feature
#   → opens PRs into antalya-26.3 (if push + pr_policy.auto_pr)
#
# On unresolved conflict:
#   * Singleton / first-of-group: nothing local survives — the entry is
#     marked "Conflict" in the GitHub Project. Resolve manually
#     in the source PR and re-run releasy.
#   * Partial group: a draft PR is opened, labelled `ai-needs-attention`.
#     Fix the conflict on that branch, push, mark the PR ready.
#
# The pipeline never stalls on a single bad unit anymore — it just
# flags it and moves on.
#
# Once a batch of rebase PRs is open, the target branch keeps moving as
# other work lands. Some PRs will eventually conflict with the new tip:
#
#   releasy refresh
#   → strictly maintenance: never opens new PRs, never creates new
#     branches, never discovers new sources. Only refreshes entries
#     already in the per-project state file.
#   → for each tracked PR with a branch + rebase PR URL:
#       fetch latest tips, attempt `git merge --no-ff origin/<base>`
#       into the PR branch. Clean merge: leave the PR alone. Conflict
#       + AI resolves: push the resolved merge commit. Conflict + AI
#       gives up: abort the merge, reset, mark the entry "Conflict".
#   → uses `ai_resolve.merge_prompt_file` (same machinery as cherry-pick
#     resolution; different in-progress operation and prompt framing).
#   → exits 1 if any PR ended up in conflict — suitable for cron / CI.
