Description Steve Traylen 2011-04-25 22:07:35 UTC
Description of problem:

file fails to identify perl scripts that contain a control character.

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

file-5.05-3.fc15.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Create a trivial perl script (file.pl) containing a control character.
   Note to enter a ^A in vi for instance press Ctrl-v and then Ctrl-A.

#!/usr/bin/perl

my $string  = "^A" ;

2. Determine file type with file command
 
$ file file.pl 
  
Actual results:
file.pl: data

Expected results:

$ file file.pl 
file.pl: a /usr/bin/perl script text executable

Additional info:

It looks like the behaviour changed between F14's
file-5.04-16.fc14.x86_64
and F15's
file-5.05-3.fc15.x86_64

previously the same file was identified as perl.

A consequence of this is that perl scripts containing control
characters are not correctly identified as perl by the rpmbuild
system and so on F15 all perl requirements are lost for scripts
that contain a control character.

Steve.

Comment 1 Jan Kaluža 2011-04-27 09:10:18 UTC
Thanks for the report. Since file-5.05, file makes difference between text files and binary files and matches only text files as perl. This is causing problem here. I will try to find out why exactly it matches control characters in normal ASCII text as binary files.

Comment 3 Fedora End Of Life 2012-08-06 20:08:49 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 15. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 15 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
