aaronpk 😮 how is this possible https://github.com/microformats/php-mf2/issues/247
#
aaronpk Loqi: why no preview
#
aaronpk ping
#
Loqi pong
#
[schmarty] yuck!
#
IWDiscordRelay <c​apjamesg#4492> 🤦
#
sknebel oof, seems indeed endless and not just stack explosion
IWSlackGateway joined the channel
#
sknebel dont have time to dig into it right now though :/
IWSlackGateway and [KevinMarks] joined the channel
#
[KevinMarks] That is pathological markup. Python parsed it but it makes no sense https://gist.github.com/kevinmarks/7e6bab548e943e1264ac35c797d7e543
#
sknebel of course it doesnt make sense as mf2, but you only can know that after parsing
#
[KevinMarks] What benighted template language generated that?
#
sknebel my first guess is "colibri page builder" for WP
#
sknebel but even if it were an artificial example, endless loop is not the right thing to do :D
#
capjamesg That is... Eek.
#
capjamesg Has there been a h-section-fluid-container all this time that I didn't know about?
#
capjamesg The close brackets only just fit on my laptop screen.
gRegor and [tantek] joined the channel
#
[tantek] no that's a made-up h-*
#
[tantek] sounds like a good "evil" test case to add once it's been fixed
#
aaronpk i'm really curious what is the minimum markup that can cause this bug
[schmarty] joined the channel
#
[tantek] indeed

gRegor Oof
btrem and [jacky] joined the channel
#
[jacky] that seems to parse okay with the Rust one
#
[jacky] this is one of those kind of scenarios where it _might_ help to have a limit on what classes to expect for `h-` objects, perhaps?
#
[jacky] though the output looks wild https://imgur.com/a/kEumEr3
[marksuth] and ur5us joined the channel
#
sknebel I *think* one could do limiting after parsing. would be interesting to experiment with what "works"
#
sknebel although we dont have a good collection of real examples sadly
#
[KevinMarks] An h-* item with no properties, only children, could be stripped?
#
aaronpk pretty sure there are some h-feeds with no properties in the wild
#
[KevinMarks] Is there a case for items that only contain children?
ur5us and [snarfed] joined the channel
#
[tantek] a page which is a list or collection can be represented as an h-feed, no properties, and a bunch of h-entry children
ur5us and gRegor joined the channel
#
[jacky] aaronpk: do you know if the PHP parser does DOM node transversal or is it doing some selector logic?
#
[jacky] The Rust parser takes the DOM walking approach (it's harder IMO but I think it prevents this looping case)
#
aaronpk no idea
#
[jacky] speaking of which, I need to break this up https://gitlab.com/maxburon/microformats-parser/-/blob/next/src/parse.rs
#
[jacky] 2k lines for the parser
#
[jacky] (including tests tho, actually)
