Here's a question: If you have a text file that contains a very long line of text (>8000 characters), is it still a text file?
I'd say Yes. But ComputerClearCase says No. Or at least hinted it meant No via several obscure error messages.
The file in question is a whole bunch of JavaScript code (part of the Microsoft AJAX release) that is not intended to be read by anyone viewing a web page, and hence is sensibly put on one line (albeit 69168 bytes in length).
Firstly, I was getting a strange error when adding them to ClearCase. Apparently, despite of the error, they were being added – I found them in a checked-out state. Upon trying to check them in, I got:
Error checking in '...MicrosoftAjax.js'. Type manager "text_file_delta" failed create_version operation.
Unable to check in '...MicrosoftAjax.js'
...followed by OK and Cancel buttons (quite how one can Cancel an operation that can't be done anyway is beyond me!)
I then thought I’d take a look at the file and did a ‘diff’ with the previous version. I got this:
Error encountered doing compare operation.
"c:\temp\ccdm02327" is not a 'text file': it contains a line exceeding 8000 bytes.
Use a different type manager (such as a compressed file).
So, according to ClearCase, a text file is not a text file if it has lines of over 8000 characters!
Anyway, the solution was to use the cleartool command line tool to add the file using a different 'type' - a compressed text file type. Note that this doesn't actually change the contents of the file, nor the way it's handled (thankfully!). Of course, once the solution was presented to me...
C:\folder\ScriptLibrary\Release>cleartool mkelem -nc -eltype compressed_text_file MicrosoftAjax.js
...everything became perfectly clear!

If you hate ClearCase, you'll get a chuckle out of this video!

That's interesting, given that compressed_text_file uses the same type manager that does not allow more than 8000 characters in a line.
The solution would be to use a type manager that does support more than 8000 characters.
i had the same problem.
trying to add compressed swfobject.js (js-library for flash stuff) which was >8K on one line was not possible.
i solved it by introducing a line break in a standard lib file, which is just ridiculous!!
If you're interesting my summary of ClearCase is crap:
http://www.aldana-online.de/2009/03/19/reasons-why-you-should-stay-away-from-clearcase/
commandprompt>cleartool chtype -nc compressed_file too_long.jsChange version manager and reconstruct all versions for "editor-min.js"? [no] yesChanged type of element "editor-min.js" to "compressed_file".
Then check in the file from Windows Explorer or from ClearCase explorer.
Hello Steve,
Don't know if you still use ClearCase, but I know these problems...
We have smart and simple plug-ins for ClearCase that might help you. Check our website: http://gomidjets.com
