In latest master, syntax-propertize application seems to be buggy in a
way I can't readily reproduce or analyze.
Consider this bit of shell:
elif [[ $c = '\' ]]; then
state=word-backslash
Sometimes, unreproducibly of course, we don't close the string at the
trailing
single quotation mark, and the rest of the buffer ends up being a
string, at least up until the single quotation mark. A similar problem
in Python sometimes leads to Python inflooping in buffers containing
strings triple-quoted with single quotation marks: it appears that we
interpret "'''" as just an empty single-quoted string, followed by a
single-quoted opener.
Did we change something about how complex syntax rules work lately?
Revision history doesn't point to anything.

There have been some changes in syntax.c not too long ago, e.g. in 3928ef2dd5b8febf3b1d9c1bfb22af3698d16bea. ^ permalink raw reply [flat|nested] 4+ messages in thread

Thanks. I'll have to read the code. Since Stefan's changes touched the syntax-propertize stuff and the problems I'm seeing involve that code path, the on-demand stuff is a prime suspect. But I have no repro, and I'm not particularly familiar with how the syntax machinery works.

Feel free to reopen, or make a new report, if there is something more substantive to say. ^ permalink raw reply [flat|nested] 4+ messages in thread
