i have an archive containing only one text file for my tests. i extract the file and then chmod -w it, so it's readonly. when i extract the same archive again, the readonly file gets overwritten by squeeze. this shouldn't happen!
btw, i only changed the permission of the extracted file in the above test. when i change the permission of the new folder to -w and try to extract again, the command exits with status 512.
Fixed in revision 25429 for tar, rar and zip (not sure if compressed files need to be escaped)
wrong bug
squeeze is not maintained anymore, closing.
