Description Sammy 2004-11-04 09:18:29 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.3; Linux; X11; en_US) (KHTML, like Gecko)

Description of problem:
Two things:

1. grep hangs if one searches through a large number of files. it does not
   seem to go through the list a file at a time.

   Removing the MBS (patch 5) patch fixes this problem.

2. There is still the problem that if you give "*" as the file list it just sits
    there for ever. Perhaps it is reading "." and ".." ?

    This happens even after removing patch5. However, in this case if
    one gives the extension of the files e.g. *.spec than it does the job.


Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. install grep 
2. go to  a directory containing a large number of files
3. grep string *

Confirmed.  Thanks for spotting it.
Comment 2 Tim Waugh 2004-11-04 10:19:53 EST
Please try 2.5.1-34:

Comment 3 Sammy 2004-11-04 14:17:43 EST
Solves the problem when extension is specified e.g. 
grep  perl *.spec  
but hangs forever for 
grep perl * 
Comment 4 Tim Waugh 2004-11-04 16:04:38 EST
It will be to do with one particular file in the directory -- please
can you try to narrow down which it is?  Thanks.
Comment 5 Sammy 2004-11-04 16:23:17 EST
OK...... i had a file named "-" (I guess a freak vi accident). Removing 
that solved it. 
Sorry about that. 
Comment 6 Tim Waugh 2004-11-04 16:58:53 EST
Wow, what are the odds of there being TWO causes for this problem?

Anyway, for future reference 'grep string ./*' avoids that sort of thing.

Thanks for the report.  By the way, do you find grep to be any faster
than previously?
Comment 7 Sammy 2004-11-04 17:02:22 EST
Yes, definitely, I have just been searching something in the firefox source 
tree and it was going very fast.
