| | | | | | This causes a drastic increase in performance. References: https://todo.sr.ht/~runxiyu/cca/7

* wsm.go: Report error when course doesn't existRunxi Yu14 days1-0/+8
| | | | | Luckily we encounter a database error before we have the chance to dereference a null pointer. But it's still good practice to check.

* Bump dependenciesRunxi Yu14 days2-3/+9
|
* {main,ws}.go: Initialize chanPool directly instead of setupChanPool()Runxi Yu14 days2-22/+1
| | | | | | It is possible to use var chanPool = make(map[string](*chan string)) directly during declaration, even if it's a global variable. There is no need to call a function to initialize it.
* courses.go: ReformatRunxi Yu14 days1-1/+1
|
* {courses,wsm}.go: Add getCourseByIDRunxi Yu14 days2-10/+8
| | | | This also deduplicates some code.
* {courses,wsm}.go: Add (*courseT).decrementSelectedAndPropagateRunxi Yu14 days2-24/+15
| | | | This is being done quite a few times, so let's make it a function.
* {courses,ws,wsm}.go: Update userCourseGroups during choose/unchooseRunxi Yu14 days3-12/+51
|
* config.go: Emit warning when fake auth is enabledRunxi Yu14 days1-0/+2
|
* bench.go: Don't close request bodyRunxi Yu14 days1-6/+0
| | | | | | The WebSocket library closes it for us (which is not behavior that I like, but fine). Closing it again causes segmentation faults as Body becomes a null pointer or something like that.
* {courses,ws}.go: Populate userCourseGroups in a separate functionRunxi Yu14 days2-32/+35
|
* {courses,ws}.go: Populate userCourseGroups for each connectionRunxi Yu2024-10-042-5/+63
| | | | | | | | | | | | | | | | | | It is way too expensive to query the database every time we need to check whether a user has chosen a course in a group. Since we can (hopefully) guarantee that there is only one usable connection for any given moment and user, we could store this data along with the connection as a local variable in handleConn, which would be eligible for garbage collection when handleConn exits. Here we create the data structures that globally represent courseTypes and courseGroups, and during the initial stages of handleConn, perform database queries to populate userCourseGroups with the groups that the user has already chosen. Note that the HELLO command handler does similar database queries, and as per the TODO listed in the comments, should be moved up here for efficiency. (HELLO also serves as some sort of an initial connection check; this should probably be replaced with WebSocket's native pings.)
* courses.go, schema.sql: Validate course{Type,Group} in server, not SQLRunxi Yu2024-10-044-30/+45

* auth.go: Improve display of OAuth 2.0 errorsRunxi Yu2024-10-041-4/+17
| | | | Implements: https://todo.sr.ht/~runxiyu/cca/9
* config.go: Return errors instead of panicing on auth.fake issuesRunxi Yu2024-10-041-3/+11
|
* {config,main}.go, cca.scfg.example: Settable static pathRunxi Yu2024-10-043-13/+8
| | | | | | | | | Because of the poor performance of using NGINX as a reverse proxy, I've added native TLS in commit 4a1a7af76408e956ebc343bf28960fdd00c00c58. Serving static files was already supported, but it was expected that people use a static web server to do so, so we didn't support a configurable static path. Now since reverse proxy setups are discouraged, it makes more sense to be better at serving static files.
* staff.html: Initial staff pageRunxi Yu2024-10-041-0/+149
| | | | | It's currently a copy of the student page with a few words changed and no checkboxes
* student.html, *.js: {main->student}.jsRunxi Yu2024-10-042-1/+1
|
* student.html: {{ .user.Name }} instead of Home in titleRunxi Yu2024-10-041-1/+1
|
* bench.go, main.js: Use an HTTPS URLRunxi Yu2024-10-042-2/+2
| | | | | This URL should be configurable in the JS at least, but I'm not sure how I should be filling out JS templates. I'll leave it hardcoded for now.
* {config,main}.go, cca.scfg.example: Support TLSRunxi Yu2024-10-043-8/+65
|
* main.go, cca.scfg.example: Remove FastCGI supportRunxi Yu2024-10-042-9/+5
| | | | | | I would love to serve FastCGI but it is a huge pain to get WebSocket working, at least with NGINX. I don't think OpenBSD httpd would be better at this either.
