* Revert "auth.go: Set SameSite=Strict"Runxi Yu2024-10-101-1/+1
| | | | | | | This reverts commit a6a5db47eb7a2040cd70dbd39e16d7de3fd9bd9f. Users are unable to log in with it. I'll look for another way to prevent CSRF.
* *.html: s/IA Docs/IA/gRunxi Yu2024-10-104-4/+4
|
* auth.go: Set SameSite=StrictRunxi Yu2024-10-101-1/+1
| | | | | We use GET requests for some administration endpoints (most importantly, the ones managing the global state).
* Implement course selection started/stopped statesRunxi Yu2024-10-1010-21/+135
| | | | Implements: https://todo.sr.ht/~runxiyu/cca/13
* staff.html: Add search functionalityRunxi Yu2024-10-101-0/+11
|
* state.go: Cancel connections when setting state 0Runxi Yu2024-10-101-8/+16
|
* newcourses.go: setupCourses must be run after commitRunxi Yu2024-10-101-10/+11
| | | | Otherwise it reads an old snapshot of the database...
* wsc.go: Check newCtx.Done() when entering other event casesRunxi Yu2024-10-101-12/+25
| | | | | | | | | | We select the context done channel when entering other cases too (see below) because we need to make sure the context cancel works even if both the cancel signal and another event arrive while processing a select cycle. It's a bit verbose and looks repetitive but is technically more correct than code without it.
* wsh.go: Remove old TODO about limiting connections per userRunxi Yu2024-10-101-7/+0
| | | | This has been implemented quite a while ago.
* wsh.go: Remove TODO about checking pgErrRunxi Yu2024-10-101-1/+0
| | | | | | | If the UUIDs actually collide, we're doomed anyway. Okay... this isn't the best way to write software that must be ultra-reliable, but this doesn't need to be ultra-reliable.
* export.go: Remove unnecessary TODORunxi Yu2024-10-101-1/+1
|
* auth.go: Remove access token expiration fields and related TODORunxi Yu2024-10-101-14/+5
| | | | | We're only using the token immediately after it is issued, so it's a bit unnecessary.
* auth.go: Remove TODO about implementing nonce checksRunxi Yu2024-10-101-7/+0
| | | | It's the OAuth provider that's responsible for checking this nonce.
* auth.go: Remove TODO about using ON CONFLICTRunxi Yu2024-10-101-7/+0
| | | | | | I think using the pgErr method actually makes the logic easier to follow especially since I'm not updating the "confirmed" field when UPDATEing but it's being initialized to false during INSERT.

* index.go, {login,student}.html: Use structs rather than maps for tmplRunxi Yu2024-10-093-22/+28
|
* *.go: Use sync.Map instead of map[int]*courseT for coursesRunxi Yu2024-10-096-73/+115
| | | | I'm not sure whether this is actually better than locking.
* {courses,wsc,wsp}.go: Usems should be sync.MapRunxi Yu2024-10-093-19/+12
| | | | | This is a classic few-reads, many-writes situation where a sync.Map would lead to substantially less lock contention.
* {courses,wsc,wsm}.go: map[courseGroupT](bool->struct{})Runxi Yu2024-10-083-8/+8
| | | | | This makes it use slightly less memory. Approximately courseGroupT bits per connection!
* style.css: Work around Firefox bug 217769Runxi Yu2024-10-081-0/+8
| | | | | | | Firefox eats the left, bottom, and right borders when tbody is empty. This is a bug known for 21 years (that was Firefox 37 or something). References: https://bugzilla.mozilla.org/show_bug.cgi?id=217769
