jcoffey-dev is traveling from Thursday 1 October through Sunday 4 October. Issues and pull requests are welcome, and will get an answer after that. Thanks for your patience.
What administrators and the server itself do to the control plane is now
recorded, from inbuxa-drafts/specs/audit-hold-lock.md (AU-1 to AU-12):
settings, accounts, domains, roles and every other registry change, with
each field's before and after (secrets only as "changed"); the fork's own
settings objects; administrator sign-ins (and failed ones to administrator
accounts), master-user and recovery-admin sign-ins, once an hour per
account, method and address; access to another account's data through
impersonation or FetchAnyBlob, once an hour; exports and tamper checks;
and registry writes the server makes on its own, named by subsystem
(system:AcmeRenewal, system:auto-ban, system:directory-sync, ...), with a
spam rules update as one summary record.
No change without its record (AU-3): before a set method changes anything,
a pending record per requested create, update and destroy is written; if
that fails, the method is refused with serverFail. Its outcome follows as
a later entry. A change interrupted by a crash stays "unfinished".
Records live in the fork's subspace under L, as one SHA-256 hash chain per
node. The chain's head is stored, never cached, and every append asserts
it, so two writers can't take the same place. Nothing can edit or delete
a record; the daily purge removes the oldest past the retention (default
730 days, minimum 90) and records where the chain now starts, so
verification still passes. security.audit-recorded (647) copies each
record to webhooks, OpenTelemetry and the log; security.audit-write-failed
(648) reports a failed write.
New JMAP objects under urn:inbuxa:jmap: inbuxa:AuditEvent/get and /query
(filters: time, actor, action, target, account, tenant, outcome, address,
text), inbuxa:AuditSettings, inbuxa:AuditExport (CSV or JSON Lines built
on the server, each line with its chain hash, ending in a manifest; the
created object names the blob and its SHA-256) and
inbuxa:AuditVerification. New permissions sysAuditGet, sysAuditExport and
sysAuditSettingsUpdate: the Administrator role gets all three, the Tenant
Administrator role gets read and export, once, on existing installs too.
A tenant administrator sees records whose actor or target is in its
tenant, including a server administrator's changes there.
Sign-in method on the session: access tokens now remember how they signed
in (password, app password, API key, OAuth client, directory, master user,
recovery admin), including across the HTTP credential cache. New OAuth
access tokens carry their client id in the sealed claims; older ones show
as client "unknown" until they expire.
The schema gains the permissions, the two events and a Management >
Compliance > Audit Log link.
Stack: the request layer boxes every inner future where it's made. Without
that, a debug build overflowed the default 2 MB worker stack on a registry
set; measured with the same request, the branch and main now overflow at
the same stack size (between 1856 and 1920 KiB, debug), so the layer adds
nothing measurable.
Tests: unit tests in inbuxa-features and jmap; system::audit::audit_log_tests
(run with --ignored) passes on RocksDB, SQLite, PostgreSQL, PostgreSQL with a
read replica, MySQL, MySQL with a replica and FoundationDB. The system, JMAP
and SCIM suites pass. authorization.rs skipped fork permissions that guard
no registry object; the audit suite checks a plain user is refused instead.
The AGPL asks a modified version to carry prominent notices saying it was
modified, and giving a date. Publishing the source is the conveyance that
asks for it, so it wants doing before the repository is public rather than
at the release.
Every upstream file the fork changed now says so in its header, beneath the
notice it came with: 164 files, found by diffing against the upstream
snapshot branch rather than by guessing, so the list is what actually
differs. Files the fork wrote itself already carry their own copyright and
need nothing. Upstream's notices are untouched, which its licence requires
and which was already true.
The README says the same thing in prose, since the obligation is on the
work as a whole and not only its Rust files.
Builds unchanged: the server and the test binary both compile.
A lossy collector subscriber keeps each inbound SMTP session that reached
MAIL FROM and each delivery attempt, info level and above and never raw
I/O, at most 1,000 events with strings cut at 4 KiB, and writes it when
the span closes as an x:Trace under the telemetry key class, scheduling
its indexing. The index task builds a document of event types, queue ids
and keywords when indexTelemetry is on. x:Trace/get derives timestamp,
from, to and size; /query filters by opening event, text, queueId and
time; /set destroys only. The data purge honours holdTracesFor. The shared
tracing and webhook suites run.
Every node writes a sample per metric on metricsCollectionInterval:
counters as the increase since its last sample, gauges always, histograms
as totals when changed. Samples are x:Metric in the registry's encoding
under the telemetry key class, ids time-ordered. x:Metric/get and /query
read them with metric and timestamp filters and full paging, hide what's
past holdMetricsFor, and the data purge deletes it. The is_enterprise
split is gone, so every gauge and histogram is collected and exported, and
queue.count is set from the queue itself. The shared metrics suite runs.
Every way of deleting mail for good (JMAP, IMAP expunge, POP3, Trash
emptying, mailbox removal) notes the message's mailboxes and keywords while
archiving is on, fixing its deadline then; when its data is finally removed
it becomes an x:ArchivedItem record, written as upstream writes them, with
its copy held until the deadline. Retention is read at deletion time, so a
change applies at once. Restore puts a message back in the mailboxes it was
in (Trash only if that was all), with its keywords, and removes the record;
over quota it stays archived. x:ArchivedItem/get returns status and
accountId; query filters on type, archivedAt and text; set requests a
restore once or destroys; /changes is a fork addition. Expired items go in
the data purge. The shared account-access rule moves to jmap::inbuxa::access.
system_tests now calls undelete::test, and the archiving gate is gone.
