* *: Overhaul structure again and embed everythingRunxi Yu10 days32-151/+144
| | | | | | | | - Remove sub-Makefiles; recursive make is annoying - Just use one top-level Makefile that builds everything - Embed templates and minified static resources into the binary - Embed all compiled documentation into the binary and serve - Embed all source into the binary and serve

* Makefile: BSD Make also supports wildcards in targetsRunxi Yu11 days1-1/+1

* Makefile: Add sem.go to source file listRunxi Yu11 days1-1/+1
|
* {config,ws}.go, cca.scfg.example: Add perf.course_update_intervalRunxi Yu11 days3-6/+14
| | | | | | This causes a drastic increase in performance. References: https://todo.sr.ht/~runxiyu/cca/7
* {courses,wsm}.go: Use in-memory structure to fetch cgroup, not SQLRunxi Yu11 days2-26/+18

* wsm.go: Omit comparison to bool constantRunxi Yu11 days1-1/+1
|
* wsm.go: Report error when course doesn't existRunxi Yu11 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.

* go.sum: go mod tidy (removing old checksums)Runxi Yu11 days1-6/+0
|
* ws.go: Index chanPool by userID, rather than session cookieRunxi Yu11 days1-5/+2
|
* {main,utils,ws}.go: Initialize cancelPool directly tooRunxi Yu11 days3-25/+1
|
* Bump dependenciesRunxi Yu11 days2-3/+9
|
* {main,ws}.go: Initialize chanPool directly instead of setupChanPool()Runxi Yu11 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 Yu11 days1-1/+1
|
* {courses,wsm}.go: Add getCourseByIDRunxi Yu11 days2-10/+8
| | | | This also deduplicates some code.
* {courses,wsm}.go: Add (*courseT).decrementSelectedAndPropagateRunxi Yu11 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 Yu11 days3-12/+51
|
* config.go: Emit warning when fake auth is enabledRunxi Yu11 days1-0/+2
|
* bench.go: Don't close request bodyRunxi Yu11 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 Yu11 days2-32/+35
|
* {courses,ws}.go: Populate userCourseGroups for each connectionRunxi Yu12 days2-5/+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 Yu12 days4-30/+45

* *.sql: New schema with ctypes and cgroupsRunxi Yu12 days3-18/+39
