Original submission:

I have mc CVS 2005-08-10-19 installed, I found, that I can't delete 
form 7z archives, and can't do some other operations (i.e. mc u7z 
cannot properly handle old 7z archives with ".\" at the beginning 
of filename)... So I wrote my own u7z version with all 
functionality, that provide p7zip archiver. Please include it to 
the mc source code.

P.S. Sorry for my bad english.

It would be better if you tweak the existing u7z script instead of 
providing a new one. I see the exisiting one has support for 
removing files from archives - why doesn't it work for you ? Does 
it print an error message of some kind ?

What's the difference if I've wrote my own version or changed the 
existent one? I've written it just a bit earlier before I've 
downloaded the CVS. I don't exactly remember but deleting wasn't 
worked in that CVS anyway. Seems like there was just an empty 
delete function.

Comment 4 by Leonard den Ottolander <leonardjo> at Wed 21 Jun 2006 05:35:56 PM UTC:

It's easier to see what changed (and if there are unwanted 
regressions) if you patch the existing version instead of writing a 
new version from scratch.

So if you want to get any improvements considered for inclusion you 
will have to rewrite your patch.

OK, Understand. I will download latest CVS, and see if I have 
something to patch un u7z.

Comment 6 by SGh <sgh> at Fri 23 Jun 2006 11:06:44 PM UTC:

Here is my patch to original u7z, fixed things:
1) Detection if we have 7z or only 7za installed. (With 7z we can 
work with all 7z-supported archives, i.e. CABs, etc... Only have to 
rename this script in ucab.)
2) Workaround for old version p7zip archives with prefix ./ in 
filenames.
3) Fixed directory creation in mcu7zip_mkdir, now it works properly.
