Package: lfm
Version: 2.3-1
Severity: important
--- DESCRIPTION ---
lfm crashes when it has to show informations (pressing "i" on the file) about a
file having this name pattern:
my_very_long_file_name_which_exceeds_the_terminal_width.(www.some-site.com)
in general, any file with a name in this form crashes it:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(zzz.xxx-ccc.vvv)
where the first part of the name (the "a"s) is a long string which exceeds the
terminal width.
--- RESULTS ---
This is what i get in my terminal after the crash:

--- TO REPRODUCE ---
$ touch
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\(www.some-site.com\)
$ lfm
$ < Once in lfm, browse for the file and press "i" on it to show its
informations >
I think the filename lenght may vary depending on the width of the terminal we
are testing in.
--- WHAT I TRIED ---
i'll refer to this filename:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(www.some-site.com)
I tested the issue creating some files with different names, trying to exclude
isolate the issue.
I couldn't come to a conclusion, or investigate more, since it has a very weird
behaviour. For example:
- using the above filename, but followed by something like
"(wwwwwwwwww.some-site.ccccccccccc)" doesn't crash it;
- using the above filename, but with no brackets and an underscore separating
the a's string from the url part, crashes it;
- using the above filename, but with no brackets and an nothing separating the
a's string from the url part, doesn't crash it;
- using the above filename, but with no hyphen, doesn't crash it;
- using the above filename, but with a shorter a's string, doesn't crash it;
I guess one should focus on the last part of the filename (the one including
brackets, dots and hyphens)
I flagged this issue as "important" since it makes the software unusable, and
there may be some more filename patterns affected by it.
Thanks for your nice work.
Bye.
