             Summary: Archiver drops file/directory mode most significant bits
                 Key: MASSEMBLY-647
                 URL: https://jira.codehaus.org/browse/MASSEMBLY-647
             Project: Maven 2.x Assembly Plugin
          Issue Type: Bug
          Components: maven-archiver
    Affects Versions: 2.4
            Reporter: Leif Rilbe


Problem detected when trying to build a zip assembly with directories having the setgid bit set.
Wanted directory mode: drwxrws---

Archiver config:
<archiverConfig>
    <!-- (rwxrws===) = 2770(oct) -->
    <directoryMode>1528</directoryMode>
    <defaultDirectoryMode>1528</defaultDirectoryMode>
</archiverConfig>

FileSet config in assembly descriptor:
<fileSet>
    <directory>${project.build.directory}</directory>
    <includes>
        <include>./</include>
    </includes>
    <outputDirectory>/</outputDirectory>
    <directoryMode>2770</directoryMode>
</fileSet>

Actual directory mode: drwxrwx---

If I do not specify <directoryMode> in the assembly descriptor, the modes from the archiverConfig prevale, thus yielding the wanted directory mode. However, this behaviour seems brittle and possibly any use of <fileMode> or <directoryMode> in the assembly descriptors seems to "break" the use of the archiverConfig modes.

>From source code analysis it seems to me that fileset modes are handled by means of the org.codehaus.plexus.components.io.attributes.FileAttributes class. This class seems to not handle the most significant file mode bits (i.e. setuid/setgid/sticky bits). It seems that the assembly plugin sometimes routes permission through this class and sometimes not, which causes the most significant bits to be sometimes lost and sometimes not.

Perhaps the best route would be to add handling of the setuid/setgid/sticky bits to the org.codehaus.plexus.components.io.attributes.FileAttributes class?
