* sandbox: replace libseccomp with chaseccompbptato2024-10-234-240/+29
| | | | | | | | | | | | | | | This drops libseccomp as a dependency. Also, move the capsicum/pledge definitions from bindings to sandbox.nim because they are only used there. Interestingly, after integrating chaseccomp I found that the stbi process would mysteriously crash by a getrandom(2) syscall. Closer investigation revealed it is only called on the initialization of glibc's malloc; presumably it had never surfaced before because libseccomp would always allocate before entering the sandbox. So I've added getrandom to our filter as well.
* color: use 64-bit SWARbptato2024-10-221-34/+15
| | | | | I originally left this at 32-bits because I was on a 32-bit arch, but that is no longer the case.
* layout: remove questionable use of newSeqUninitializedbptato2024-10-211-5/+2

* poll: nimifybptato2024-10-201-8/+22
| | | | until it's fixed upstream...
* dynstream: refactorbptato2024-10-2018-255/+224
| | | | | | | | | | * consistently use cint instead of FileHandle - this was another remnant of winapi support; on posix, they are the same. * move "blocking" field to PosixStream * recvFileHandle -> recvFd, sendFileHandle -> sendFd * merge serversocket into dynstream * merge auxiliary C functions into dynstream_aux
* dynstream, serversocket: use posix instead of nativesocketsbptato2024-10-2010-106/+56
| | | | | | | | | | | nativesockets is a wrapper over posix and winapi, but we don't support winapi, so we can just fall back to PosixStream instead. SocketStream remains as a constraint over PosixStream to allow sendFileHandle/recvFileHandle. As a nice side effect, we can drop some allowed syscalls from the seccomp filter.
* sandbox: do not ask for signal permissionsbptato2024-10-171-3/+0
| | | | | On a second thought, no timeouts for name resolution is fine - and even if it weren't, it's better implemented in the loader.
* layout: fix inline float + position: absolute bugbptato2024-10-161-5/+6
| | | | | As per standard, float "only applies to elements that [...] are not absolutely positioned."
* css: add reverse video extensionbptato2024-10-152-0/+3
| | | | | | | | | | | | Called -cha-reverse. Mostly to solve the problem that code tags are indistinguishable from regular text - on a graphical browser this is normally served by monospace font, but we always use monospace... So now the default ua.css adds reverse video to code and xmp. pre remains as it was, because it means "preformatted", not "monospaced". Also, it would mess with our whatever-to-HTML converter output.
* layout: fix float positioning in inline contextsbptato2024-10-151-60/+120
| | | | | | also fixes a bug in the previous commit where whitespacenum would be reset on absolute positioning + missing absolute margin handling without top/left/etc.
* layout: correct `position: absolute' (FINALLY)bptato2024-10-152-157/+229
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a) resolution of `position: absolute' percentage sizes with an indefinite containing block size (wait what?), and b) positioning of `position: absolute' inner block boxes inside inline boxes. a) is possible because `position: absolute' does not affect its parent's layout. I would love to have a long talk with whoever thought that specifying it like this is a good idea. You know, just because you can... anyways, shockingly enough, this was still the more straightforward part. b) forced me to change the box tree to allow blocks inside inlines, which is ugly, but no big deal. Two questions then remained: 1. *where* to put such boxes, and 2. *how large* these boxes should be; this is hardly obvious since an inline box does not have an unambiguous width or height. Of course the CSS standard, never too eager to fulfill my basic expectations, says nothing about this (other than "it's not defined"). So I first tried to reverse engineer what Gecko does, and after hours of pain and suffering I realized... that it's broken LOL https://bugzilla.mozilla.org/show_bug.cgi?id=489100 Therefore I ended up (partially) copying Blink behavior, which, while equally nonsensical as Gecko (and of course divergent), at least does not change after a partial layout. Thank you LayoutNG for saving my sanity. As for the practical benefits: this fixes the bug where Invidious [video] tags wouldn't show up. Hey, it's something! Still left to-do: `position: absolute' for `display: inline' boxes.
* pager: refactor mailcap, console; misc fixesbptato2024-10-147-280/+262
| | | | | | | | | * use more PosixStream (because it has double-close checking) * factor out some common mailcap operations * move console from client to pager * fix case-insensitive mime type matching * replace convoluted fdin/fdout comparison logic (that only accidentally worked) with a boolean flag
* twtstr, toml: misc cleanupbptato2024-10-134-13/+9
| | | | | * remove unused DateTime toml type * add parseIntP for pointer-size int parsing

* loader: improve CGI header parsingbptato2024-10-121-32/+39
| | | | | | * accept HTTP status line * reject status codes with >3 length * reduce pointless copying
* loader: fix potential nil derefbptato2024-10-121-1/+1
| | | | rare, but possible

* dom: prevent leaking window size through media queriesbptato2024-10-121-3/+4
|
* gmifetch: rewrite in Nimbptato2024-10-125-47/+39
| | | | | | | | | | This finally makes it possible to use socks5 for Gemini. Also slightly refactored the config, to make it easier to pass on the config dir. By the way, the known_hosts file is now stored in the config dir too. The adapter will try to move it to there from the old location.
* dom: html -> documentElementbptato2024-10-103-9/+6
| | | | it's effectively a dupe, except html wouldn't work in XML
* env: fix getComputedStyle arg2bptato2024-10-101-1/+1
|
* promise: remove newPromisebptato2024-10-103-17/+6
| | | | normal construction is enough (and it wasn't really used anyway)
* layout, pager: preserve tabs on display, selection & outputbptato2024-10-104-29/+101
| | | | | | | | | | | | Substitute tabs with one of eight PUA characters based on their width, and convert them back in the pager: * TUI mode always prints spaces, but now handles tabs appropriately on cursor movement * dump mode tries to preserve hard tabs, but uses soft tabs when that is not possible (e.g. tabs after a margin, tab with background color, etc) * selection mode always outputs hard tabs.

* client: fix redirected buffers jumping back to parent on reloadbptato2024-10-071-0/+5
| | | | | replaceBackup was not being cleared, so the next gotoURL with a replace pointing to such buffers wouldn't work.
* pager: do not choke on empty editor commandbptato2024-10-071-2/+4

* layout: small cleanupbptato2024-10-071-14/+11
| | | | the length check is not needed, we do that outside the loop already
* color: reduce CellColor size, misc color refactoringbptato2024-10-0610-128/+148
| | | | | | * split out CSSColor from CellColor; now CellColor is just 4 bytes (which helps reduce FormatCell size) * unify color function naming (still not perfect)

* sixel, term: reduce half-dump special casingbptato2024-10-043-22/+37
| | | | | | | Makes it slightly easier to debug image output. Also, we stop sending dimension headers, and no longer check for the scheme env var to make CLI invocation a bit less annoying.
* sixel: transparency improvementsbptato2024-10-031-4/+4
| | | | | | | * don't set transparency when raster attributes suffice - it seems terminals don't background-fill in that case either. * fix transparency in encoder standalone mode * update comments

* poll: reset events on errorbptato2024-10-021-1/+5
| | | | | poll will return an error if interrupted, which may leave the events in their previous state. Make sure revents is set to 0 first.
* term: "fix" GNU screen not respecting query sequence orderbptato2024-10-011-9/+22
| | | | | | | | | | | | | wtf ... OK, it's a "fix" as much as you can fix this. I'm not adding a timer just to work around screen silently reordering my output. (Who thought this would be a good idea??) Unfortunately, this means that your background/foreground colors won't get detected when using screen. Not that they would have been until now.

* pager: improve rewrite-url semanticsbptato2024-09-301-7/+19
| | | | | | | | | | | | | Previously, it just changed the URL before loading the site; now it's an actual redirect. Technically, the previous behavior was more flexible, because it let you apply siteconf rules exclusively for sites where you redirected from. Practically, this was not very useful, and probably unexpected for anybody trying to use the feature. This also fixes a bug where the loader filter would be set for the original page, so you couldn't switch from https to http, etc.
* timeout: accept err stream as parambptato2024-09-304-16/+11
| | | | | gets rid of a todo. (not sure why I thought this was important, but it sure looks nicer)

* dom: optimize element size, remove importc hack & dead codebptato2024-09-304-111/+85
| | | | | This switches CAtom to uint32; it seems better to use the same size on all platforms.
