[Bug 2067276] Re: Extremely slow regex searches on files with very long lines

[Sebastien Bacher]

Thank you for your bug report. Any chance you could report also the
issue upstream? We don't have anyone on the Ubuntu side actively working
on the less sourcecode so it's not likely it will be picked and resolved
from this launchpad report. Also it would help a bit if you attached a
testcase example to the report

Title:
  Extremely slow regex searches on files with very long lines

Status in less package in Ubuntu:
  Triaged

Bug description:
  Regex searches on files with very long lines are extremely slow.
  During the search (can take up to an hour) ^C and ^Z are not working.

  Older versions (less-487 on ubuntu-18.04 and less-530 from opensuse
  leap-15.1) find same regex on same file within one second.

  24.04 affected as well as 22.04.
