fix: reconcile repo visibility instead of trusting the ingest-time flag
`events.public` was decided once, when a row was ingested, from whatever
the forge reported at that moment — and every poller is incremental (the
github events feed caps at 90 days, search at its top-1000 window, the
per-repo scanner at a `since` cursor, the gitea feed at page 1 after the
first run). Nothing ever revisited a repo, so flipping one to private
upstream only relabelled whatever activity happened afterwards: its
history kept serving commit messages, issue titles and the repo name
indefinitely. The reverse flip was equally frozen.

The github and gitea sources now run a reconciliation pass before
ingesting. github reuses its existing repo discovery, which already
re-reads `private`/`isPrivate` for everything reachable, and only spends
a request on repos we're still exposing that discovery didn't return;
gitea has no equivalent bulk endpoint, so it asks per repo, once a day
rather than once a tick. Repos already hidden are skipped — they can't
leak, and staying hidden is the safe direction to err in. A 404 counts
as private (with the user's own token, a repo still in reach answers 200
even when private, so 404 means gone or transferred), while rate limits
and transient errors flip nothing; the pass runs in both directions, so
a spurious hide is undone by the next successful poll.

That needs a repo key the worker can UPDATE against, hence `events.repo`
— a stored generated column, and now the single definition of the
payload -> repo mapping that list_events, list_projects,
activity_summary and language_daily_counts each carried their own copy
of. Consolidating them fixes an attribution gap along the way:
/search/issues items carry neither `repo.name` nor
`repository.full_name`, only `repository_url`, so every issue and PR
backfilled through search resolved to NULL in all four queries. Those
events now attach to their repo, which both makes them reconcilable and
means they show up in /projects and /activity/summary.

Also closes a leak that predates the flip problem: `/v1/languages/repos`
had no visibility gate at all, and repo_languages is populated for every
repo the worker discovers, private ones included. Repo names were on the
wire (and baked into the prerendered HTML via the dehydrated query
cache) regardless of what `events.public` said. Rather than a second
visibility column to keep in sync, the response now derives it — a
repo's languages are exposed exactly when at least one of its events is.

Verified against postgres 16: the generated column extracts every
payload shape the four sources produce (and NULLs a non-github
`repository_url`), the reconciliation UPDATE flips all three github
event shapes for a repo in one statement and is a no-op on re-run, the
gitea host filter excludes other hosts while treating rows predating the
`_host` stamp as local, and /v1/languages/repos drops a repo once its
events go private.

moments

personal activity timeline and portfolio site. polls public sources (github, gitea, mercurial, bugzilla), stores raw payloads in postgres, and serves a dashboard + project detail views to a react frontend.

successor to the now-defunct grenade-events-react, which depended on mongodb stitch (retired by mongodb in september 2022).

data sources

source impl endpoint notes
github events github.rs /users/{user}/events last 90 days, etag-optimised polling
github search github_search.rs /search/commits + /search/issues historical backfill, 1000-result cap
github repo github_repo.rs /user/repos + /repos/{o}/{r}/commits full commit history, no cap, weekly poll
gitea gitea.rs user + org activity feeds auto-discovers orgs, filters by user
mercurial hg.rs json-log?rev=author() revset-based, one-shot backfill then skip
bugzilla bugzilla.rs /rest/bug?creator= mozilla bugzilla

hg repos are archived (mozilla retired hg). the worker skips hg after the first successful scan. for bulk ingestion, script/hg-ingest.sh clones repos locally and inserts via psql, avoiding rate limits on hg-edge.mozilla.org.

frontend routes

path page description
/ or /dash dashboard contribution graphs (daily + all-time weekly) + ranked project cards with forge icons and language info
/activity timeline filterable activity feed with source toggles, date range slider, and event limit
/activity/:timespan timeline pre-filtered by date (YYYY-MM-DD) or range (YYYY-MM-DD..YYYY-MM-DD)
/project/:source/* project detail repo readme, language breakdown bar, per-repo activity timeline
/cv resume loaded from github gist, markdown-rendered

shared layout provides nav header (dash, activity, cv + external links) and footer across all routes.

api endpoints

method path description
GET /v1/healthz liveness probe
GET /v1/events?from=&to=&source=&repo=&limit= reshaped timeline items
GET /v1/sources per-source summary (count, earliest, latest)
GET /v1/projects per-repo aggregated stats (commits, issues, prs, date range)
GET /v1/activity/daily?from=&to= per-day event counts for contribution graphs
GET /v1/forge/{source}/*?host= proxy to github/gitea apis (avoids cors)
GET /v1/og/contributions.png server-rendered contribution graph as png (resvg)

the og image endpoint renders the all-time weekly contribution graph as svg, rasterizes to png via resvg, and serves it with a 1-hour cache. used as the og:image meta tag for social media previews.

local development

cargo build --workspace
cargo run -p moments-api      # serves on 127.0.0.1:8080
cargo run -p moments-worker   # starts all pollers
cd ui && npm install && npm run dev  # vite dev server on :5173

the api expects a postgres reachable at DATABASE_URL. in production this is an mtls connection using the host cert. for local dev against a throwaway database:

DATABASE_URL=postgres://localhost/moments cargo run -p moments-api

migrations live in crates/moments-data/migrations/ and run automatically on worker startup. the api connects as moments_ro and never runs migrations — the worker (as moments_rw) is the schema owner.

private work is counted but never described: events.public gates the detail endpoints (events, projects, activity/summary, languages/repos) while the count endpoints (activity/daily, activity/hourly, sources, languages/daily) include everything, so a private repo shows up as volume on the contribution graph without leaking its name or commit messages. because that flag is stamped at ingest and the pollers are all incremental, the github and gitea sources re-read current repo visibility on each poll and rewrite events.public across the affected repo's whole history — a repo flipped to private upstream stops being described, one flipped back to public reappears.

deployment

deployment is driven by Gitea Actions, not an operator workstation:

  • .gitea/workflows/deploy.yml — on push to main (or manual dispatch): lint/test gate, build the api + worker as static musl binaries and the prerendered web bundle, then deploy each component over SSH as the gitea_ci user with scoped sudo (asset/sudoers.d/).
  • .gitea/workflows/refresh.yml — daily schedule: (or manual): rebuilds and redeploys only the web tier, re-baking the prerendered crawler snapshot without bouncing the api/worker.

both workflows carry the infra truth (hosts, ports, paths) in their env: blocks and render the nginx vhost through the shared script/render-site-conf.py, which fails the build if any template placeholder is unset rather than shipping it. one-time per-host provisioning (the gitea_ci user, its authorized_keys, the scoped sudoers drop-in) is script/infra-setup.sh.

the shape of the deployment:

component notes
api binds the port from api.config.bind; firewalld service moments-api
worker no listening port; pollers only
web per-site nginx ingress; /api/* reverse-proxies to the api host
db postgres mtls, passwordless

postgres roles moments_rw and moments_ro must exist on the primary, with pg_ident.conf.d/<host>.conf mapping the api host's fqdn to moments_ro and the worker host's fqdn to moments_rw. see asset/sql/bootstrap-moments.sql, asset/postgres/ident.conf.tmpl, and script/db-perms.sh.

the worker's poller tokens are Gitea repo Actions secrets (QUERY_GITHUB_TOKEN, QUERY_GITEA_TOKEN — the bare GITHUB_TOKEN/GITEA_TOKEN names are reserved by Actions). deploy.yml's deploy-worker job substitutes them into the matching {{NAME}} placeholders in worker.env.tmpl at deploy time; secrets come from the runner environment and never touch a command line.
