* 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.
* config: fix relative includes with -Cbptato2024-10-311-2/+3

* layout: refactor flow and fix some bugs in the processbptato2024-10-3121-351/+347
| | | | | | | | | | | | * factor out `margin' field from box state * get rid of RootInlineFragment * `nested' -> `children' * get rid of repositionChildren pass; now we handle relative positioning and -cha-center/-cha-right separately * cha-center, cha-right no longer applies to floats * use consistent naming scheme for tests * fix float bottom margin strut not being flushed * fix inline floats changing non-fit-content width

* dynstream: restrict permissions to userbptato2024-10-311-0/+1
| | | | | the man page says this isn't really portable, but it's better than nothing
* 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.)

* container: fix crash on isearch between redirectsbptato2024-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | Sadly, pushCursorPos may not be paired with a popCursorPos in case the container in question is replaced during the isearch. The easiest way to reproduce this is: * start request to a page that redirects * start isearch * redirection happens, now the old container is gone * type something Then, popCursorPos would try to pop the cursor position from the new container. An alternative (and better) solution would be to add a weak ref to the container as the line edit data. Sadly, we don't have weak refs, and I don't want to hack them in with finalizers. (But maybe I should. Hmm.)
* md2html: support setext headingsbptato2024-10-261-15/+37
| | | | also, parse the last paragraph properly
* sftp: switch to libssh2bptato2024-10-2610-220/+246
| | | | | | | | | | | | | | | | | | | Just to remove a level of indirection; the libcurl API is annoying to deal with when you don't even need asynchrony. It doesn't change anything in actual dependencies, because libcurl uses libssh2 too - however, now only http depends on libcurl, which makes reducing it to an optional module feasible. Still, I've listed libssh2 (along with OpenSSL - long overdue) in the readme just in case some OS doesn't pull in the headers by default as a libcurl dependency. Also, fix some bugs: * fix missing CWD command in FTP * resolve directories even if they don't end in / * allow links without -> in dirlist
* chaseccomp: update readmebptato2024-10-261-3/+3

* selectorparser: fix parsing of invalid pseudo elementsbptato2024-10-263-16/+56
| | | | | Found this because the 5th largest tech company on Earth cannot bother itself with trivial matters such as "writing valid CSS".
* cssparser: do not accept invalid rulesbptato2024-10-253-2/+7
| | | | | | This isn't exactly clear from the standard's wording, but e.g. *display: inline must be discarded (because it incorrectly starts with a delim token).
* layout: fix nested absolute positioning, refactor initial size resolutionbptato2024-10-254-109/+138
| | | | | | | | | | Nested position: absolute was broken, so fix it. Also, it makes no sense to dispatch inside layoutBlockChild when we know the expected resolution algorithm upon calling it anyway, so now we do that statically. Finally, fix some bugs in position: absolute size resolution.

* termcap: merge into termbptato2024-10-233-35/+29
| | | | | again, not that useful to put it in a separate module if only term uses it
* sandbox: replace libseccomp with chaseccompbptato2024-10-2318-255/+537
| | | | | | | | | | | | | | | 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 SWARbptato2024-10-222-36/+17
| | | | | I originally left this at 32-bits because I was on a 32-bit arch, but that is no longer the case.
* ua.css: disable reverse video on <code> in <pre>bptato2024-10-211-0/+4
| | | | | | | | | | | | The intention is that only inline code tags have reverse video; otherwise it often messes with syntax highlighting. I've made it a descendant selector (instead of a cheaper parent selector) because I can easily imagine markup like <pre><div><code>... which really shouldn't enable reverse video either.
* layout: remove questionable use of newSeqUninitializedbptato2024-10-211-5/+2

* md2html: misc improvementsbptato2024-10-211-10/+7
| | | | | | | | * fix line not being printed on pre end * add head to pre tags - this isn't in CommonMark, but it makes it easier to write hybrid markdown/HTML. * use character range constants
* poll: nimifybptato2024-10-201-8/+22
| | | | until it's fixed upstream...
* dynstream: refactorbptato2024-10-2019-256/+225
| | | | | | | | | | * 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.
* config.toml: add ?q=/path Google redirectbptato2024-10-181-2/+6
| | | | apparently this is relative to the current page
* sandbox: do not ask for signal permissionsbptato2024-10-174-3/+3
| | | | | On a second thought, no timeouts for name resolution is fine - and even if it weren't, it's better implemented in the loader.
