Review request for KDE Utils, KDE Usability and Raphael Kubo da Costa.


Bugs: 335411
    http://bugs.kde.org/show_bug.cgi?id=335411


Repository: ark


Description
-------

Errors while extracting an archive entry in copyFiles() were being
discarded without informing the user, who would then believe the entire
extraction had worked correctly. We now emit the error() signal when
there is an error and cancel the extraction.

It also makes sense to adapt the code in writeFile() to the same format
of using a switch() to test archive_write_header()'s return code to ease
future maintenance.

Additionally, none of the error messages use archive_error_string()
anymore. While this means the messages are less detailed, it also means
users who use a translated KDE will not see part of the error messages
hardcoded in English.

Testing
-------

Creating archives still works as before, and error messages during extraction (such as the one in bug 335411) are properly reported.


Thanks,
