Description Tim Waugh 2004-11-24 21:05:58 UTC

This is for:

 * correctness regressions compared to grep-2.5.1-31
 * performance regressions compared to grep-2.5.1-31
 * benchmark results
 * even a simple "installed it here and it seems to work"

Comment 1 Rob Hughes 2004-12-03 12:51:53 UTC

grep -f and fgrep fail on binary files at 
 
 read(3, "eck\0freopen\0__wuflow\0re_search\0f"..., 12288) = 12288 
 open("/usr/lib/gconv/gconv-modules.cache", O_RDONLY) = 4 
 fstat64(4, {st_mode=S_IFREG|0644, st_size=21544, ...}) = 0 
 mmap2(NULL, 21544, PROT_READ, MAP_SHARED, 4, 0) = 0xf6ddc000 
 close(4) = 0 
  
And there is sits as long as I'm willing to wait (up to an hour so 
far). Doesn't matter whether I'm root or a user. Strings file|grep 
<something> doesn't show this problem, nor does it occur on ascii 
files.

Comment 2 Tim Waugh 2004-12-03 13:11:02 UTC

Thanks for the report.  This seems to be a regression relative to FC3.  Here is
the command line that reproduces it:

fgrep foo /bin/ex

(/bin/ex from vim-minimal-6.3.030-3)

Comment 3 Tim Waugh 2004-12-03 15:56:37 UTC

Fixed package is grep-2.5.1-31.2.  Please re-test.  Thanks!

Comment 4 Rob Hughes 2004-12-03 16:08:43 UTC

Works now. Thanks!

Comment 5 Rob Hughes 2004-12-03 16:15:41 UTC

Just wanted to mention that grep_2.5.1-40_i386.rpm from rawhide shows the same 
regression.

Comment 6 Tim Waugh 2004-12-03 16:27:29 UTC

Yes, I fixed rawhide at the same time.
