New issue 263 by [email protected]: Malformed YAML hogs CPU for a long
time
https://code.google.com/p/vim/issues/detail?id=263
What steps will reproduce the problem?
1. take puppet (ruby) source code (*) and either paste it into open YAML
file, insert it there with :r or rename the puppet file to *.yml and open
it with vi
2. wait for a **long** time while vi spins CPU
......
3. Finally "pkill -9 vi" from another terminal because it's still
unresponsive
(*) The problem might be specific to a code where YAML tries to parse
regexps or st. like that. This is a file that causes several second hangup,
by adding characters to 'baz' string the lag increases dramatically:
cat test.yml
class foo {
bar {
baz
=> "aaaaaaaaaaaaaaaa+bbbbbbbbbbbbbb+cccccccccccccc/dddddddddddddd+/eeeeeeeeeeeeee+ff/ggggggggggggg/hhhhhhhhhhhhhh/jjjj+kk+lllllllllllll/mmmmmmmmmmmmmm//nnnnnnnnnnnn+ooooooooooooooo=",
}
}
What version of the product are you using? On what operating system?
Ubuntu 14.04.1 LTS - 2:7.4.052-1ubuntu3
Debian GNU/Linux jessie/sid - 2:7.4.430-1
Ubuntu 12.04.5 LTS - 2:7.3.429-2ubuntu2.1 - this one shows much less lag,
but this might be caused by the fact that it's a desktop system unlike
previous two.
