The deb task doesn't preserve the filesystem permissions

[i30817]

I whenever i tried to build, even with this:
http://pastebin.com/raw.php?i=FmMaXiux

When i used lintian

BUILD SUCCESSFUL
Total time: 27 seconds
E: bookjar: control-file-has-bad-permissions conffiles 0755 != 0644
W: bookjar: extended-description-line-too-long
E: bookjar: non-standard-file-permissions-for-etc-init.d-script etc/init.d/bookjar 0644 != 0755
W: bookjar: script-not-executable etc/init.d/bookjar

(notice it reports etc/init.d/bookjar is not executable even though i was set explicitly before the deb task)
Whatever i do, whatever the permissions before the files go into the deb task it doesn't seem to change this, so i can only guess the task is modifying the files but not setting a appropriate permission back again.

Could you try again by replacing the data element with a fileset? It should preserve the permissions.

    <deb destfile="${name}.deb" compression="gzip"  control="debian/pkg/DEBIAN">
        <fileset dir="debian/pkg/data" />
    </deb>

Actually the right solution is to use a tarfileset. Until jdeb uses the Java 7 nio2 API it's not possible to preserve the permissions from the filesystem.

[i30817]

Even a tar fileset won't work, because different things on the data dir (or indeed the control dir, where i didn't see the option to use a tar) need different permissions and tarfileset sets them to all the files.

If i gave a (exec-ed) tar file would it work? BTW, i don't mind using java 7. In fact, the best option might be a fork. Where in the code do you copy files?

[i30817]

It looks pretty gnarly. You only use inputstreams. I wonder if there is a wrapper output stream that saves file permissions and reapplies them on the end

[ebourg]

You can use several tarfilesets, one per type of permission, or you can use a permission mapper. There are some examples in the documentation : https://github.com/tcurdt/jdeb/blob/master/docs/ant.md

What about the control directory?

[i30817]

Now i'm confused too:
http://developer.ubuntu.com/packaging/html/debian-dir-overview.html

there are a number of files in that article (changelog, .desktop) that i was putting in their final directories in the data instead of the control directory. Will jdeb do the right thing on this or is it too distribution specific?

[ebourg]

The .desktop file has to be put in the right directory (typically into /usr/share/applications), jdeb will not move it automatically.

[i30817]

Bummer i was hoping that the distro installer did (and that jdeb exposed the mapping variable mechanism so i could use the [[]] syntax in all control/** files)

What is the best way to address the permission issue in a Maven build?

I'm interested in providing a fix for this issue. Would you be interested by such a contribution?

[tcurdt]

@prapicault what kind of fix do you have in mind?
