The load dialog shows the GitHub account state with sign-in, sign-out
and repository-selection links. A clone that needs authorisation shows
a Sign in with GitHub or Grant repository access button, and the
repository is resumed automatically on return from GitHub.
/api/github/login redirects to GitHub with a single-use state bound to
the session; the callback exchanges the code for a user token kept in
memory and expired with it. Clones pass the token through git config
in the environment, never the URL or arguments, and ignore host git
config and credential helpers. Failed clones report authRequired
(signin or install) so the frontend can offer the right next step.
Configured with GITHUB_CLIENT_ID, GITHUB_CLIENT_SECRET, GITHUB_APP_SLUG.
A background sweep every minute drops snapshots unused for an hour,
finished jobs, and uploads never committed, deleting their workspaces.
At most 8 snapshots are held; the least recently used is evicted.
Indexing used to discard every existing snapshot, so concurrent users
wiped out each other's landscapes. Only the same session's previous
snapshot and workspace are replaced now.
An HttpOnly, SameSite=Lax session cookie is issued when a job is
created. Job and snapshot routes return 404 to any other session, so
indexed source is only readable by the browser that loaded it.
Go's regexp backtracker dominated indexing. Each pattern now runs only
when a cheap necessary-condition check passes, cutting indexing of the
Go standard library source from 4.7s to 1.4s.
Adds BenchmarkIndexDirectory.
Implements the API routes (jobs, progress events, snapshots, search,
entities, source delivery with release) to net/http and serves the
static frontend from the same binary on the same origin.
