* load permissions properly in a third placeKartik K. Agaram2022-01-041-2/+9
|
* when editing a function, show its callersKartik K. Agaram2022-01-034-10/+63
| | | | | | No way to select between them. That complicates the UI too much when we do so much with the cursor. But it's still useful to suggest things to type in after ctrl-g.
* start saving callers of functionsKartik K. Agaram2022-01-033-2/+55
| | | | | I think this is significantly slowing things down. Perhaps we should sample or something.

* error handling when editing file permissionsKartik K. Agaram2022-01-021-1/+21
| | | | | | | Still highly non-ideal. Lua is a dynamic language, and has low ability to detect syntax errors within functions. Perhaps I should run a test call after every edit.
* bugfix: policies must end in newlineKartik K. Agaram2022-01-021-3/+3
| | | | I believe kilo kinda naturally enforces that. We'll see.

* editable file permissionsKartik K. Agaram2022-01-024-51/+192
| | | | | | | | | | | | | | | | | | | | | Extremely cruddy implementation: - I'm still unclear on how to represent the advice function: - How to handle errors when loading user configuration? Currently I refuse to start. - Whole function? More errors to handle in header and so on. What if the function is renamed? - Just body? Needs more structured editing support. - Lots of duplication, particularly between the permissions in the menu and the permissions screen. I don't know how to show the hostname at the time of connect() or bind(), so networking is going to remain a boolean for now. It's also unclear what effective constraints we can impose on what gets discussed with a specific hostname. Everything outside the computer is out of one's control. One trick I learned is for consistently grabbing ASan logs on abort: It's always safe to redirect stderr with ncurses!

| | | | Zero guarantees of compatibility at this point.
* reorgKartik K. Agaram2021-12-251-24/+24
|
* network calls are now sandboxedKartik K. Agaram2021-12-251-1/+10
| | | | | | | I _think_ I don't need to gate other socket calls; you can't do anything without bind() and connect(). And they should be good places to dump more precise details later about the kind of server or client connection being attempted.
* file open() is now sandboxedKartik K. Agaram2021-12-253-15/+36
| | | | | | | In the process we now also have a mechanism for Teliva to overlay errors while apps run. Might make sense to make that available to apps as well. But I'm starting to realize that any app access to the Teliva areas of the screen is fraught with risk.
* flesh out very preliminary UIKartik K. Agaram2021-12-253-19/+154
| | | | | | | Our sandboxing model is a blunt caricature, just two booleans. But let's see how far this gets us. Still doesn't persist, and definitely has no effect.

|
* mock sandbox status and some initial colorsKartik K. Agaram2021-12-252-1/+30
| | | | | | | | Current plan: - two booleans to gate file and network access, respectively - false shows as green, true shows as orange - if _both_ booleans are true, then both show as red to indicate that there are no protections.
* update all places when changing color schemeKartik K. Agaram2021-12-251-0/+1
|
* fix menu colors in all color schemesKartik K. Agaram2021-12-251-1/+2
| | | | | | | | It looks like attron doesn't actually enable colors near 256, even though https://linux.die.net/man/3/attron suggests it does. > COLOR_PAIR values can only be OR'd with attributes if the pair > number is less than 256.
* a little more reorgKartik K. Agaram2021-12-251-79/+84
| | | | | | | | Put stuff people messing with Teliva apps are likely to need above the C interface. The state of documentation for Teliva app creators is still quite poor. All they really have to go on is the example apps.
* reorg: pull Teliva-specific stuff out of lua.cKartik K. Agaram2021-12-259-1061/+1071
| | | | It should now be easier to diff against the Lua 5.1 sources upstream.
* drop stdin/stdout/stderr and Lua default filesKartik K. Agaram2021-12-251-115/+13
| | | | | | | This isn't necessarily for sandboxing, but they don't really work right now in the presence of ncurses, and it seems better to not include broken stuff. Maybe we can get them to coexist with ncurses down the road.
* sandbox: no popenKartik K. Agaram2021-12-252-57/+1
| | | | Again, too difficult to sandbox for now.
* tlv format for transient editor stateKartik K. Agaram2021-12-252-18/+21
| | | | | Stop interpreting arbitrary Lua code when loading editor state. We don't need that power or security risk.
* sandbox: no system()Kartik K. Agaram2021-12-251-7/+1
| | | | | Too hard to sandbox. Maybe we'll get back to it if there's some use case only it can satisfy.
* cleaner test messageKartik K. Agaram2021-12-231-3/+2
| | | | Was printing over passing tests for some reason.
* errors during tests are now handledKartik K. Agaram2021-12-221-1/+8
| | | | | | | | | | | | | | | | I should have documented that I'd never actually seen that code path trigger before. Here's a minimal test that did it just now: function test_foo() return a+1 end E2: [string "test_foo"]:2: attempt to perform arithmetic on global 'a' (a nil value) A simple missing variable doesn't do it since it just evaluates to nil. Without this commit, the above test was silently continuing to the main app after failing tests.
* more precise control over menu orderKartik K. Agaram2021-12-221-2/+10
| | | | I can't believe I didn't notice this until now.
