Item10209: rewriteshebang Failure with unexpected perl path input

The tools script rewriteshebang does not work with my path to the perl executable to be used.

My perl path is /depot/perl-5.8.3/bin/perl and the script fails on line 96 of tools/rewriteshebang.pl in release 1.1.2.

if ( $new_path =~ /(^(\.)?(\/{1}\w+)+(\.exe)?$|^:alpha:{1}:(\\{1}\w+)+(\.exe)?$|^perl$)/i )

It reports the following error

ERROR: Regex verfication of given path failed. Going to exit.

In release 1.1.0 and all previous versions, I only had to fix a simple file test to get it to work. The fix is more difficult now and is not easily scriptable so my upgrade script becomes more difficult.

My workaround is to rewrite this line as:

if ( $new_path =~ /^(\S+)$/)

There is another line in the script with the same problem that is not executed in my situation.

There is a fix already committed for 1.1.3 for other issues that addresses this regex a bit.

Please see if the updated regex in http://trac.foswiki.org/changeset/10023 works for your situation. If not, we'll work on this further for 1.1.3. Thanks

The version for release 1.1.3 seems to work.

Thanks for testing. Setting this to Waiting for Release so the resolution shows up in the 1.1.3 release notes.

One thing I noticed when running this is that it reports 0 files changed but it actually did change the perl version used in the first line of all the scripts.

Enter path to interpreter [hit enter to choose '/linux/depot/perl-5.8.3/bin/perl']: /depot/perl-5.8.3/bin/perl
Enter path to interpreter [hit enter to choose '/depot/perl-5.8.3/bin/perl']: 

The new Perl interpreter uses version "5.008003". If your path was just
"perl" this number might be wrong as in web server context you may use a
different environment. The verified version is not recommended for a current
Foswiki installation.
Are you still sure you want to use this path (y/n): y

New Perl interpreter uses version 5.008003

"No" will only change "shebang" lines of scripts found in the directory
where the script is run from. Are you sure you want to change scripts
in the 2 directories:
../tools
../bin
(y/n)?: no
