* loader: better error handlingbptato2024-06-201-1/+1
| | | | we no longer crash on broken codecs. yay
* img, loader: separate out png codec into cgi, misc improvementsbptato2024-06-202-31/+139
| | | | | | | | | | | | | | | * multi-processed and sandboxed PNG decoding & encoding (through local CGI) * improved request body passing (including support for output id as response body) * simplified & faster blob()/text() - now every request starts suspended, and OngoingData.buf has been replaced with loader's buffering capability * image caching: we no longer pull bitmaps from the container after every single getLines call Next steps: replace our bespoke PNG decoder with something more usable, add other decoders, and make them stream.

* js: fix various leaks etc.bptato2024-05-033-26/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously we didn't actually free the main JS runtime, probably because you can't do this without first waiting for JS to unwind the stack. (This has the unfortunate effect that code now *can* run after quit(). TODO: find a fix for this.) This isn't a huge problem per se, we only have one of these and the OS can clean it up. However, it also disabled the JS_FreeRuntime leak check, which resulted in sieve-like behavior (manual refcounting is a pain). So now we choose the other tradeoff: quit no longer runs exitnow, but it waits for the event loop to run to the end and only then exits the browser. Then, before exit we free the JS context & runtime, and also all JS values allocated by config. Fixes: * fix `ad' flag not being set for just one siteconf/omnirule * fix various leaks (since leak check is enabled now) * use ptr UncheckedArray[JSValue] for QJS bindings that take an array * allow JSAtom in jsgetprop etc., also disallow int types other than uint32 * do not set a destructor for globals
* cssparser: refactorbptato2024-05-011-10/+7
| | | | | | | | | * factor out skipWhitespace * remove streams dependency (cssparser could never stream without blocking the event loop, so we were just passing a StringStream in all cases, which made the whole streaming pointless.)

* Initial image supportbptato2024-04-251-1/+1
| | | | | | | | | | | | | | | | | * png: add missing filters, various decoder fixes * term: fix kitty response interpretation, add support for kitty image detection * buffer, pager: initial image display support Emphasis on "initial"; it only "works" with kitty output and PNG input. Also, it's excruciatingly slow, and repaints images way too often. Left undocumented intentionally it for now, until it actually becomes useful. In the meantime, adventurous users can find out themselves why: [[siteconf]] url = "https://.*" images = true
* dom: remove unnecessary/unused propertiesbptato2024-04-222-11/+8
| | | | | | | | | | * remove some properties we no longer use * convert novalidate into a reflected attribute * fix satClassList * remove reference to root node in every Node The last one is an obvious win when considering how often rootNode is used vs the memory used by a pointless pointer on every single object.

| | | | | | * separate params with ; (semicolon) instead of , (colon) * reduce screaming snake case use * wrap long lines
* js: remove automatic function -> closure conversionbptato2024-04-152-7/+5
| | | | | | | | | | | | | | | It's a bad idea for several reasons: * it's inefficient; must allocate an environment for a closure in Nim, even though we already have one in JS * writing macros for automatically creating functions with variadic arguments is suprisingly difficult (see the entire `js/javascript' module) * it never really worked properly, because we never freed the associated function pointer. We hardly used it anyway, so the easiest fix is to get rid of it completely.
* dom: use pointers instead of numerical ids for collectionsbptato2024-04-141-10/+9
| | | | | | | | | | The "id" scheme had obvious problems when multiple documents existed. Originally it was needed because the old hacky integration with QuickJS would occasionally result in objects being moved to other addresses. This has been fixed long ago when I decided to vendor in a fork, so we can just use pointers as ids unique to the entire process.
* dom: add onclick attribute supportbptato2024-04-143-30/+78

* js: proper distinction between Opt/Optionbptato2024-03-243-16/+17
| | | | | | | | | | | | | | | | until now, this had very strange (and inconsistent) semantics: * err() was used for exception propagation, but also as a null value * Option accepted undefined as a none value, but not null * Opt and Option were used interchangeably (and mostly randomly) Now, Result is always used for error reporting, and err(nil) means JS_EXCEPTION. (Opt is a special case of Result where we don't care about the error type, and is not used in JS.) Option on the other hand means "nullable variation of normally non-nullable type", and translates to JS_NULL. In JS we mainly use it for turning strings nullable.
* io: derive DynStream from RootObj (not Stream)bptato2024-03-242-9/+11
| | | | | | | | This way they are no longer compatible, but we no longer need them to be compatible anyway. (This also forces us to throw out the old serialize module, and use packet writers everywhere.)
* buffer: form fixes & improvementsbptato2024-03-244-41/+58
| | | | | | | * fall back to text for unimplemented input types * add custom prompt to all text-like input types * show min/max for range * fix accidental override of repaint

* buffer: send title during load + other title stuffbptato2024-03-211-2/+2

* buffer: add markURLbptato2024-03-191-4/+4

* Move around some modulesbptato2024-03-144-4/+299
| | | | | | | | * extern -> gone, runproc absorbed by pager, others moved into io/ * display -> local/ (where else would we display?) * xhr -> html/ * move out WindowAttributes from term, so we don't depend on local from server
* rudimentary support for <video>, <audio>bptato2024-03-131-0/+22
| | | | | we just treat them as img tags. lazy, but works suprisingly well -- so long as the server sends us a Content-Type, anyway.
* loader: remove applyHeadersbptato2024-03-121-2/+2
| | | | | | | Better compute the values we need on-demand at the call sites; this way, we can pass through content type attributes to mailcap too. (Also, remove a bug where applyResponse was called twice.)
* loader: rework process modelbptato2024-03-112-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally we had several loader processes so that the loader did not need asynchronity for loading several buffers at once. Since then, the scope of what loader does has been reduced significantly, and with that loader has become mostly asynchronous. This patch finishes the above work as follows: * We only fork a single loader process for the browser. It is a waste of resources to do otherwise, and would have made future work on a download manager very difficult. * loader becomes (almost) fully async. Now the only sync part is a) processing commands and b) waiting for clients to consume responses. b) is a bit more problematic than a), but should not cause problems unless some other horrible bug exists in a client. (TODO: make it fully async.) This gives us a noticable improvement in CSS loading speed, since all resources can now be queried at once (even before the previous ones are connected). * Buffers now only get processes when the *connection* is finished. So headers, status code, etc. are handled by the client, and the buffer is forked when the loader starts streaming the response body. As a result, mailcap entries can simply dup2 the first UNIX domain socket connection as their stdin. This allows us to remove the ugly (and slow) `canredir' hack, which required us to send file handles on a tour accross the entire codebase. * The "cache" has been reworked somewhat: - Since canredir is gone, buffer-level requests usually start in a suspended state, and are explicitly resumed only after the client could decide whether it wants to cache the response. - Instead of a flag on Request and the URL as the cache key, we now use a global counter and the special `cache:' scheme. * misc fixes: referer_from is now actually respected by buffers (not just the pager), load info display should work slightly better, etc.
* catom: merge TagType with AttrTypebptato2024-03-043-110/+131
| | | | | it's inefficient and pointless to treat them differently, so just derive a new enum from TagType with a macro

* quickjs: reduce diff with upstreambptato2024-03-021-2/+3
| | | | | | * the uint8array thing is probably from txiki.js, but we never used it * upstream now has JS_GetClassID, importing that instead... (so this commit won't build :/)
