reassign 581807 gecko-mediaplayer 0.9.9.2-1
retitle 581807 cannot unpack with /usr/lib/firefox/plugins ->
../mozilla/plugins symlink
quit
Hi Cesare,
Brandon reported trouble unpacking the latest version of gecko-mediaplayer.
The package contents include
/usr/lib/mozilla/plugins/gecko-mediaplayer.so (a file)
/usr/lib/firefox/plugins/gecko-mediaplayer.so ->
../../mozilla/plugins/gecko-mediaplayer.so (a symlink)
Unfortunately, some setups include a symlink that makes these paths the
same. The symptoms are different depending on the dpkg version used to
unpack:
1. Old dpkg versions unpack the file first, then the symlink. So
in the end, there is no usable gecko-mediaplayer.so plugin,
just a self-referential symlink!
2. Newer dpkg versions unpack everything to temporary files (with
names ending in .dpkg-new) first. First comes the file, then the
symlink overwrites it.
Then it renames them all into place: first the symlink is renamed
in mozilla/plugins, then it is found missing in firefox/plugins.
So old dpkg versions produce a broken installation, and new ones at
least complain.
I suspect the simplest solution would be to not ship the
/usr/lib/firefox/plugins/....so file at all, but to create the symlink
if needed in the postinst script.

Could you say more about how this symlink arose? I have faint
memories of such a symlink long ago, but it’s been a while since I
used Firefox.
Thanks for the help,
Jonathan
