* forkserver: also skip SIGTERM socket unlinkbptato2024-05-201-5/+1
| | | | rationale: see previous commit
* buffer: never unlink controlling socket in cleanupbptato2024-05-201-5/+2
| | | | | | | | The pager already unlinks it, so ideally this should change nothing. (This was causing buffer processes to core dump on OpenBSD, because I forgot that I removed unlink promise. Better keep code paths the same when possible...)
* html: improve Request, derive Client from Windowbptato2024-05-201-5/+6
| | | | | | | * make Client an instance of Window (for less special casing) * misc work on Request & fetch * improve origin comparison (opaque origins of same URLs are now considered the same)

* config: separate tmp dir for sockets, usersbptato2024-05-161-2/+9
| | | | | | | * add $LOGNAME to the tmp directory name, so that tmpdirs of separate users don't conflict * use separate directory for sockets, so that we do not have to give buffers access to all cached pages
* css/values -> css/cssvaluesbptato2024-05-161-1/+1

* buffer: fix multipart formsbptato2024-05-112-40/+39
| | | | | | | | | * fix enctype not getting picked up * fix form data constructor requiring open() syscall (which gets blocked by our seccomp filter) * add closing boundary to multipart end * pass fds instead of path names through WebFile/Blob and send those through bufwriter/bufreader

* Initial image supportbptato2024-04-251-6/+16
| | | | | | | | | | | | | | | | | * 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
* buffer: fix switch from charset decoder to UTF-8 validatorbptato2024-04-201-1/+3
| | | | | The validator is used only if the decoder is nil, so it must be cleared in switchCharset.
* sandbox: seccomp support on Linuxbptato2024-04-182-25/+53
| | | | | | | | | | | | | | | | | We use libseccomp, which is now a semi-mandatory dependency on Linux. (You can still build without it, but only if you pass a scary long flag to make.) For this to work I had to disable getTimezoneOffset, which would otherwise call localtime_r which in turn reads in some files from /usr/share/zoneinfo. To allow this we would have to give unrestricted openat(2) access to buffer processes, which is unacceptable. (Giving websites access to the local timezone is a fingerprinting vector so if this ever gets fixed then it should be an opt-in config setting.) This patch also includes misc fixes to buffer cloning, and fixes the LIBEXECDIR override in the makefile so that it is actually useful.
* Update code stylebptato2024-04-172-73/+74
| | | | | | * separate params with ; (semicolon) instead of , (colon) * reduce screaming snake case use * wrap long lines
* js: remove automatic function -> closure conversionbptato2024-04-151-8/+4
| | | | | | | | | | | | | | | 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: add onclick attribute supportbptato2024-04-141-23/+34
| | | | | + better align attribute-based event handler behavior with other browsers
* sandbox: add OpenBSD pledge/unveil supportbptato2024-04-032-5/+7
| | | | | | | | | | | | pledge is a bit more fine-grained than Capsicum's capability mode, so the buffer & http ("network") sandboxes are now split up into two parts. I applied the same hack as in FreeBSD for overriding the buffer selector kqueue, because a) I didn't want to request sysctl promise b) I'm not sure if it would even work and c) if it breaks on OpenBSD, then it's broken on FreeBSD too, so there's a greater chance of discovering the bug.
* buffer: fix markURL in plaintextbptato2024-03-291-3/+31
| | | | | | | We must HTML escape data, or the fragment parser will parse plain text as markup. (However, just running htmlEscape() on data is not enough; that would also mark <, ', etc. as &gt, &apos. So we only escape after the regex is executed.)
* fflush() before forksbptato2024-03-281-0/+6
| | | | | seems like a good idea, especially because CGI uses stdout as the IPC mechanism
* Add capsicum supportbptato2024-03-282-13/+40
| | | | | | | | | | | | | It's the sandboxing system of FreeBSD. Quite pleasant to work with. (Just trying to figure out the basics with this one before tackling the abomination that is seccomp.) Indeed, the only non-trivial part was getting newSelector to work with Capsicum. Long story short it doesn't, so we use an ugly pointer cast + assignment. But even that is stdlib's "fault", not Capsicum's. This also gets rid of that ugly SocketPath global.
* buffer: fix cancel()bptato2024-03-271-12/+20
| | | | | | | | | | * fix mismatch between return value & read value that would either crash or freeze the browser depending on its mood * add an assertion to detect the above footgun * fix some resource leaks * fix iteration over a table that called a function which altered the table in buffer's cancel() * if user cancels before anything is loaded, destroy the container too
* buffer: fix getTitle never returning in some casesbptato2024-03-241-0/+2

* client, forkserver: remove useless codebptato2024-03-241-1/+0

* js: proper distinction between Opt/Optionbptato2024-03-241-6/+6
| | | | | | | | | | | | | | | | 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.
* buffer: fix clonebptato2024-03-241-7/+8

* io: derive DynStream from RootObj (not Stream)bptato2024-03-242-65/+53
| | | | | | | | 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.)
* bufreader: add initPacketReaderbptato2024-03-241-3/+1
|
* buffer: form fixes & improvementsbptato2024-03-241-45/+72
| | | | | | | * 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
* io: add bufreaderbptato2024-03-212-66/+56
| | | | analogous to bufwriter
* catom: at -> satbptato2024-03-211-8/+8
| | | | just for consistency
* buffer: send title during load + other title stuffbptato2024-03-211-7/+20
| | | | | | | * send title to pager as soon as it's available * expose `title' to DOM * rename undocumented `getTitle' js function to `title' getter in Container
* buffer: also buffer input readsbptato2024-03-211-38/+49
| | | | this is buffer reading from pager
* buffer: also buffer reads for packetsbptato2024-03-201-12/+16
| | | | | Since we know the length of packets, we can also read them in in one call. Though I really wish we could do this without the StringStream.
* buffer: add markURLbptato2024-03-191-2/+44
| | | | Useful when browsing plaintext files; w3m has it too.
* Move SIGCHLD ignore call to forkserverbptato2024-03-171-0/+1
| | | | seems like it confuses popen()
* forkserver: set process titles for processesbptato2024-03-171-0/+4
| | | | | this is unfortunately truncated on Linux, but I don't care enough to hack around this
* io: add BuferedWriterbptato2024-03-162-41/+53
| | | | | | | | | | Unsurprisingly enough, calling `write` a million times is never going to be very fast. BufferedWriter basically does the same thing as serialize.swrite did, but queues up writes in batches before sending them. TODO: give sread a similar treatment
* Clean up BufferConfigbptato2024-03-151-0/+9
| | | | | | | | It was defined in the wrong module, and unnecessarily included LoaderClientConfig. Also, referrerPolicy was not being propagated to loader clients because it was (incorrectly) in BufferConfig instead of LoaderClientConfig.
* Move around some modulesbptato2024-03-142-3/+3
| | | | | | | | * 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>bptato2024-03-131-7/+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: rework process modelbptato2024-03-112-282/+145
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* buffer: fix bug of eating chars before invalid UTF-8bptato2024-03-051-2/+2
| | | | | | | using this API is suffering (`n' is the last *valid* character ever since the validator API got fixed, so it must be included in the slice.)
* strwidth, renderdocument: small refactoringbptato2024-03-031-1/+1
| | | | | | * put attrs pointer in state * simplify width() * use unsigned int as ptint to avoid UB
* buffer: improve/fix onload return valuesbptato2024-03-031-6/+12
| | | | | | | | | Only report when bytesRead has changed, otherwise we get unnecessary load requests. (This means -2 return value no longer exists; it did not work correctly anyway.) Also, fix the race condition that broke onload returns when onload happened before client requested load.
* buffer: do not incrementally display in headless modebptato2024-03-021-3/+4

* buffer, client: fix deadlock with send() callsbptato2024-02-291-13/+20
| | | | | | | | | | This is an ancient bug, but it got much easier to trigger with mouse scrolling support so it's time to fix it. (The bug itself was that since both the client and buffer ends of the controlling stream are blocking, they could get stuck when both were trying to send() data to the other end but the buffer was full. So now we set the client end to non-blocking.)

* misc refactoringsbptato2024-02-271-19/+18
| | | | | | * rename buffer enums * fix isAscii for char 0x80 * remove dead code from URL
* buffer: reset prevStyled in switchCharset, reshapebptato2024-02-271-3/+5
| | | | | | | | reshape must do a render from zero, as it's a last resort for users to fixup the page on a rendering bug. switchCharset must reset prevStyled for obvious reasons (it refers to a dead document).
