I thought this was an RCS problem (RCSProblemsOnWindows), but I am not convinced now. The symptom is that when I put the following:

1
2
3
4
5
-- Main.MartinCleaver - 21 Feb 2001 

On editing the page for the second time, this turns to:

1

2

3

4

5

-- Main.MartinCleaver - 21 Feb 2001 

And the problem gets worse on subsequent edits. .

I think it might be related to KfmBrowserSupportForEditing

Answer

Okay! Fixed it! It is related to KfmBrowserSupportForEditing On Windows you don't want the extra LF on resubstitution. I haven't worked out why, it might be something to do with whether Binary mode has been specified on the handle that reads in the file. Anyhow this fudges away the problem - alter bin/save[.pl].

Hmm. I think the files might have been marked as text or binary or something. Certain old files in my web continue to exhibit this behaviour, but none of the new files do!

We had the same problem and used the fix mentioned above. In addition, to avoid the sporadic problem remaining with already existing files, we adapted the edit script as follows:

NOTE: please go to edit mode to prevent Twiki from reformatting the code example!

sub main
{
...
old: $text =~ s/&/&\;/go; 

old: $text =~ s/
old: $text =~ s/>/>\;/go; 

old: $text =~ s/\t/	/go; 


new: #MCH Added following lines to remove carriage returns 

new: $text =~ s/\\\n//go; 

new: $text =~ s/\r//go; 


...
}

What I also did was go through wiki.pm and mark binmode on all the file handles.
