Implementations

impl ChangesetStore

pub fn new(db: PgPool) -> Self

pub async fn create( &self, repo_id: RepoId, session_id: Option<Uuid>, agent_id: &str, intent: &str, base_version: Option<&str>, agent_name: &str, ) -> Result<Changeset>

Create a changeset via the Agent Protocol path. Auto-increments the number per repo using an advisory lock. Sets source_branch to agent/<agent_name> and target_branch to main so platform queries that read these NOT NULL columns always succeed. agent_name is the human-readable name (e.g. “agent-1” or “feature-bot”).

pub async fn get(&self, id: Uuid) -> Result<Changeset>

pub async fn update_status(&self, id: Uuid, status: &str) -> Result<()>

pub async fn update_status_with_reason( &self, id: Uuid, status: &str, reason: &str, ) -> Result<()>

Update changeset status and record the reason for the transition.

pub async fn update_status_if( &self, id: Uuid, new_status: &str, expected_states: &[&str], ) -> Result<()>

Update changeset status with optimistic locking: the transition only succeeds when the current state matches one of expected_states. Returns an error if the row was not updated (state mismatch or not found).

pub async fn update_status_if_with_reason( &self, id: Uuid, new_status: &str, expected_states: &[&str], reason: &str, ) -> Result<()>

Like update_status_if but also records a reason for the transition.

pub async fn set_merged(&self, id: Uuid, commit_hash: &str) -> Result<()>

pub async fn upsert_file( &self, changeset_id: Uuid, file_path: &str, operation: &str, content: Option<&str>, ) -> Result<()>

pub async fn get_files(&self, changeset_id: Uuid) -> Result<Vec<ChangesetFile>>

pub async fn get_files_metadata( &self, changeset_id: Uuid, ) -> Result<Vec<ChangesetFileMeta>>

Lightweight query returning only file metadata (path, operation, size) without loading the full content column.

pub async fn record_affected_symbol( &self, changeset_id: Uuid, symbol_id: SymbolId, qualified_name: &str, ) -> Result<()>

pub async fn get_affected_symbols( &self, changeset_id: Uuid, ) -> Result<Vec<(SymbolId, String)>>

pub async fn find_conflicting_changesets( &self, repo_id: RepoId, base_version: &str, my_changeset_id: Uuid, ) -> Result<Vec<(Uuid, Vec<String>)>>

Find changesets that conflict with ours. Only considers changesets merged AFTER our base_version — i.e. changes the agent didn’t know about when it started.
