1.74.1.  RHBA-2009:0481: bug fix update


This update has already been released (prior to the GA of this release) as FASTRACK errata RHBA-2009:0481
An updated grep package that fixes various bugs is now available.
Grep searches through textual input for lines matching a regular expression.
This updated grep package includes fixes for the following bugs:
  • while searching certain immense binary files in which the newline character did not appear for large expanses (for hundreds of megabytes of text, for instance), grep may have missed a subsequent match. Because the grep utility is not intended to process arbitrarily-long files in this manner, this updated version now exits with a "line too long" error message and an appropriate error code under these conditions. (BZ#483073)
  • when operating on particular multi-byte character sets (but not, notably, UTF-8), grep could enter an infinite loop and become unresponsive. This has been fixed in this updated package so that grep is once again able to process these multi-byte character sets without hanging. (BZ#479151)
  • certain output control option combinations could cause the grep tool to segmentation fault. With this updated package, these combinations work as expected and no longer cause a segmentation fault. (BZ#452127)
  • the example attached to the "--label" option description was not illustrative enough: as documented, the option actually had no effect. The updated package contains an improved example that shows the "--label" option's utility, both in the manual and info pages. (BZ#484366)
All users of grep are advised to upgrade to this updated package, which resolves these issues.
