Revoke by selector: everything a principal issued, everything under a grant - #152
Conversation
… grant ctrlrun revoke takes one id, and the ids are in the events file. During an incident the operation an operator reaches for is everything this principal issued or everything under this grant, and until now that was a script over the events file written under pressure. --created-by PRINCIPAL and --under ID are queries over rows that already exist. No new StateStore method: delegations(include_revoked=True) and revoke_delegation are what they read and call, and the filter sits above the store. Each match is revoked exactly as one id is, one at a time, through the same Control.revoke, so a run that stops halfway leaves the rows it reached revoked and the rest untouched, and a second run finishes. --by is unchanged. The roadmap called the new selector --by <principal>, which is the opposite meaning on an option that already exists and records who performed the revocation, so the selector is --created-by and every script written against 0.7.0 keeps working. An empty selector exits non-zero and names what it searched for: during an incident a mistyped name that exits 0 reads as a finished job. --under is strictly beneath, so it leaves the id it names alone; an operator who wants that row as well already has ctrlrun revoke <id>. Still no unrevoke. T272 to T280, on both backends, and the killed run is a real command in its own process killed on its first recorded revocation. Two things building it settled, in SPEC-v0.8 §14.1: a kill between the row write and the event append leaves a revoked row with no event, which is v0.3 behaviour rather than anything the selector adds and which T276 bounds rather than assumes; and two guards were green under mutation because a later guard fired with the same exit code, so the tests now assert which one ran.

- Around line 1047-1050: Update the --created-by parsing logic around agent,
separator, and user so an empty user after a separator is rejected with
click.UsageError, while preserving valid AGENT and AGENT/USER inputs and the
existing no-match behavior for well-formed values.
In `@tests/test_revoke_selector.py`:
- Line 125: Update PostgreSQL URL handling in the test setup so existing query
parameters in POSTGRES_URL are preserved while ctrlrun_schema is added
correctly. Align _Workspace._open and _peel_schema to parse the URL with the
same query-parameter logic, ensuring the configured scratch schema is extracted
rather than defaulting to public.

…outside its schema Two findings, both real. --created-by "human-cfo/" set the separator and left the user empty, which the filter read as "the user is the empty string", matched nothing, and reported §7.5's no-match error. A typed-and-lost user is not "every user", and the widest reading of an ambiguous command is the wrong default during an incident, so it is a usage error that names the two forms. The message is asserted, not the exit code, because without the guard the command exits non-zero anyway through the no-match error: the same subsumed shape the mutation table caught twice in this item already. M9a covers it. And the worse one, in the test rather than the code. The Postgres fixture built its store URL with an f-string, so a CTRLRUN_TEST_POSTGRES carrying "?sslmode=require" produced a second "?", _peel_schema read ctrlrun_schema as part of the sslmode value, and the schema fell back to public: the test would have passed while the command wrote outside its scratch schema, into the database every other test shares. The URL is now built with urllib.parse, and _Workspace keeps the base URL and the schema apart rather than re-parsing them out of the CLI's own argument, since a test that reads a different schema from the one the command wrote to asserts nothing. Ten mutations now, all caught. Signed-off-by: arpan <contact@arpanghoshal.com>
Both CodeRabbit findings were real, and the second one was worse than minor
1. The test asserts the message, not the exit code, because without the guard the command exits non-zero anyway through the no-match error. That is the third time in this item that a guard was subsumed by a later one with the same exit code, which is why every refusal here asserts which guard fired. 2. The Postgres fixture could have written outside its scratch schema. It built the store URL with an f-string, so a The URL is now built with Mutation table, now ten
30 tests in the file now, both backends. Re-running the full local gate; its counts go in a comment. |

CONTRIBUTING.md's first shape of a false green), so the tests changed rather than the code:--created-by a/b/crefusal deleted,a/b/cparses as the agentaand the userb/c, matches nothing, and exits non-zero through §7.5's empty-selector error instead. The test asserted an exit code where it had to assert a message.Control.revokeis idempotent and appends no second event, so the event count was unchanged. What the skip is actually for is the terminal: without it a rerun printsrevoked <id>for every row it did not revoke. The test now asserts that line's absence.What building it settled (
SPEC-v0.8.md§14.1)A killed run can leave a revoked row with no event, and that is v0.3 behaviour rather than anything the selector adds.
Control.revokewrites the row and then appends the event: two writes, no transaction over the pair, andStateStoreis frozen (v0.6 §9.2). ASIGKILLbetween them leaves the delegation revoked, correctly and durably, with nothing in the log. A selector run does not create the window; it makes it easy to land in, because it takes the same two writes two hundred times instead of once.T276's first draft asserted equality between events and revoked rows, which is stricter than the code has ever promised. It now asserts the bound that is true: at most one row may be mid-write. Closing the window needs the row and the event in one store call, which is a store method, which is the maintainer's call and not an item's.
Polling the store to trigger the kill made T276 pass for the wrong reason. Opening a
StateStoreper poll costs more than the two hundred revocations it is watching, so the kill landed after the child had finished and the test asserted a window it had not opened. It polls the JSONL event file instead, which the command is already appending to.Verification

Item 8 regenerates it inctrlrun-docs.No independent review required for this item: it touches no authorization decision, adds no store method, and changes no evaluation. Its reviewer, if one is wanted, confirms that a selector revokes exactly the rows one id would have revoked, one at a time.
