Overview ¶
Package filter implements the TaskCreationFilter chain.
Package filter implements the TaskCreationFilter chain — predicates that decide whether a vault task should be created for a PR at all.
This is one of two decision chains in the watcher:
- TaskCreationFilter (this package): "should we create a task?"
- trust.Trust (sibling package): "given we create a task, should it auto-process or route to human_review?"
See docs/watcher-decision-chains.md for the full split rationale.

Functions ¶
func ParseRepoAllowlist ¶
ParseRepoAllowlist parses a comma-separated allowlist string into a slice of host-qualified repo keys. Whitespace is trimmed; empty entries are skipped. Returns (nil, nil) for empty input (allow-all). Entry well-formedness is NOT validated here — repoallowlist.IsAllowed handles malformed entries gracefully at match time (logs and skips).
Types ¶
type PR ¶
type PR struct {
AuthorLogin string
IsDraft bool
Title string
UpdatedAt libtime.DateTime
RepoKey string
}
PR is the filter-evaluation input derived from a GitHub pull request. Only the fields needed for task-creation filter decisions are included.
type TaskCreationFilter ¶
type TaskCreationFilter interface {
// Skip returns true if the PR should be excluded from task creation.
Skip(pr PR) bool
}
TaskCreationFilter decides whether a single PR should be skipped (no vault task created). Implementations return true to skip.
func NewAgeFilter ¶
func NewAgeFilter(maxAge libtime.Duration, referenceTime libtime.DateTime) TaskCreationFilter
NewAgeFilter returns a filter that skips PRs whose UpdatedAt is older than (referenceTime - maxAge). A zero maxAge disables the filter.
referenceTime is the watcher's startTime — captured once at process start and threaded through factory.CreateWatcher. This avoids any CurrentDateTimeGetter injection: a watcher pod's lifetime is bounded by its restart cadence (hours), and the age filter's granularity is days, so sub-day clock drift is irrelevant.
func NewBotAuthorFilter ¶
func NewBotAuthorFilter(allowlist []string) TaskCreationFilter
NewBotAuthorFilter returns a filter that skips PRs whose author matches any entry in the configured allowlist (exact match). An empty allowlist never skips.
func NewDraftFilter ¶
func NewDraftFilter() TaskCreationFilter
NewDraftFilter returns a filter that skips draft PRs (the author is signaling "not ready for review"). GitHub's draft state is the primary signal; literal "WIP" prefixes in the title are handled by a separate WIP filter (see wip_title_filter.go when added).
func NewRepoAllowlistFilter ¶
func NewRepoAllowlistFilter(allowlist []string) TaskCreationFilter
NewRepoAllowlistFilter returns a TaskCreationFilter that skips PRs whose RepoKey is not in the allowlist. An empty allowlist never skips (allow-all).
func NewWIPTitleFilter ¶
func NewWIPTitleFilter() TaskCreationFilter
NewWIPTitleFilter returns a filter that skips PRs whose title starts with "WIP:" or "WIP ". The author has explicitly signaled the PR is not ready for review.
type TaskCreationFilterFunc ¶
TaskCreationFilterFunc adapts a function to the TaskCreationFilter interface (function-as-implementation, useful for inline filters).
func (TaskCreationFilterFunc) Skip ¶
func (f TaskCreationFilterFunc) Skip(pr PR) bool
Skip implements TaskCreationFilter for the function adapter.
type TaskCreationFilters ¶
type TaskCreationFilters []TaskCreationFilter
TaskCreationFilters is a slice composite: skip if ANY member votes skip. An empty slice never skips (no filters configured = process every PR).
func (TaskCreationFilters) Skip ¶
func (fs TaskCreationFilters) Skip(pr PR) bool
Skip returns true if any contained filter votes skip. Iteration is short-circuit on first hit (filters are pure predicates with no side effects, so there is no audit-trail concern).
