* layout: improve image sizingbptato2024-11-091-24/+16
| | | | | fixes a bug where only setting max-height and width would not re-scale the image
* renderdocument: basic stacking context supportbptato2024-11-098-27/+59
| | | | | negative z-index and inline positioning are still not respected, but better than nothing I guess.

* layout: adjust fixed positioningbptato2024-11-091-2/+12
| | | | | | | | | | | | | | | | | | In CSS, `position: fixed' either a) moves the box on scroll (with `@media screen'), or b) repeats the box on every page (with `@media print'). a) would completely mess up our document model, and even if it didn't, the renderer couldn't handle a redraw on every single scroll. b) sounds better, but still doesn't work because it's incompatible with `@media screen' semantics. e.g. in a) I can read text despite any banner on the bottom of the screen, because the box moves when I scroll, but in b), the same box will obscure some text on every single page. So instead, make the `position: fixed' containing box width: max(:root.width, 100vw); height: max(:root.height, 100vh)). This is completely non-standard, but at least both TOC-like fixed boxes *and* banners are placed somewhere that makes some sense.
* layout: fix a few more flex sizing bugsbptato2024-11-095-61/+118
| | | | | | | | * fix min-width, max-width, etc. not being accounted for properly on the main axis * fix fit-content sizing being overridden for flex items * fix baseline not being set * somewhat unrelated: fix firstBaseline not being set for block boxes

* layout: fix initial flex item width calculationbptato2024-11-087-18/+60
| | | | | | | | | | | | | | | Before, the initial layout of a flex item would have inherited the parent's sizing constraint. This almost worked, except when a descendant of a flex item with an unspecified width would resolve its percentage against this incorrectly inherited width - per standard, this must resolve to auto. Also, the shrink case was wrong, because it did not scale the unit to the respective widths; the standard mandates this as well. Hopefully I got it right this time. Finally, this fixes positioned inline container blocks not being set as the absolute container.
* Fix some C warnings, more makefile vars, etc.bptato2024-11-089-58/+74
| | | | | | | * add some more env vars to makefile * remove fpermissive from GCC builds * update Monoucha * fix borked seccomp filter length safety check (ugh)
* poll: fix clear()bptato2024-11-072-3/+6
| | | | | setLen(0) inside the events iterator was wrong; it should have just set all items to -1.

* gopher: rewrite in shellbptato2024-11-057-175/+123
| | | | | | also, make gopher2html more lenient, and add some functioning error handling in our nc clone. (other scripts still have to be updated to benefit from this)

* chaseccomp: lock down clone; fix mprotect on bionicbptato2024-11-045-10/+23
| | | | | | | | | | | * add restrictions on clone for buffer filter - hardcoded it for musl, glibc and bionic. hopefully they don't change it too soon... * remove define directive from gen_syscalls - now the arch nr check is hardcoded in gen_defs. makes things a bit less complex. * fix borked mprotect filter on bionic - this completely broke the browser.
* dynstream: fix crash on *BSDbptato2024-11-041-1/+4

* layout: remove inline roundingbptato2024-11-024-6/+5
| | | | | | | | | It broke styles like "margin-top: -5px; padding-top: 5px", because the margin would be taken as-is, and the padding rounded to 0. Now they cancel each other out again. (I think I had added this to reduce error caused by line-height, but we don't have line-height anymore.)

* layout: fix yet another inline float bugbptato2024-11-013-1/+12
| | | | | | | | | you can't just set the BFC offset to your own offset when the BFC's origin is your inner offset. (in block layout, this is addressed by initBlockPositionStates & co, but we don't call that for inline because the offset is already resolved there anyway. so this is a special case)

* layout: simplify a bit, fix some inline float bugsbptato2024-11-016-113/+103
| | | | | | | | | | | | | | * simplify "positioned" value calculation: - don't include it in ResolvedSizes, since it's unused in most layouts - resolvePositioned for both absolute and relative positioning - use "size" instead of "space" for absolute positioning - include parent width in layout so that renderdocument does not have to account for it * return bottom margins as regular return values instead of var * fix child bottom margins being discarded in inline floats * fix inline float not including the parent block position in its BFC position
* chaseccomp: revert parts of d9ca197ebptato2024-10-313-5/+6
| | | | | | | | | * abort on network sandbox violation - it's probably better not to, but I want to think this through a bit more before changing it for good (and then do it consistently, i.e. also for the buffer process.) * revert case variable quoting - the lack of field splitting is specified by POSIX, and the readme states that we target POSIX. no need to be paranoid about imaginary shells.

* chaseccomp: fix compilation with newest dash, misc changesbptato2024-10-318-36/+80
| | | | | | | | | | | | | | * fix matching on unstripped whitespace: caught after upgrading to upstream dash & chaseccomp wouldn't compile * add defines to ensure that we computed the filter length correctly * inline cut_label * EPERM on sigaction, sigprocmask, gettid, and kill on tgkill (so a crash doesn't trigger sandbox violations) * move SIGSYS handler to C and add one for the network The last change removes the stack trace from SIGSYS, but gives us the syscall number which is probably more useful. (Indeed, we don't even have a stack trace in release builds.)

* config: refactor, accept more possible config dirsbptato2024-10-2825-234/+216
| | | | | | | | | | | | | | | | | | | | | I'm starting to favor dotfiles over XDG basedirs, but there's no reason why we couldn't have both. So now the search path is: 0. if config was set through -C, use that 1. $CHA_CONFIG_DIR is set -> $CHA_CONFIG_DIR/config.toml 2. $XDG_CONFIG_HOME is set -> $XDG_CONFIG_HOME/chawan/config.toml 3. ~/.config/chawan/config.toml exists -> use that 4. ~/.chawan/config.toml exists -> use that Notably, this makes it so the default directory is ~/.chawan *if* you don't have an existing config.toml file. So in that case known_hosts will be placed in ~/.chawan/known_hosts. However, configurations with a config in ~/.config/chawan/config.toml continue to work as expected, as for those the known_hosts file remains inside ~/.config/chawan/. Finally, I've added a default user CGI directory to reduce friction in setting CGI up. (Like known_hosts, it's also relative to whatever config dir you have.)
