Bug 435054 – x11-libs/qt-gui-4.8.3: 44qt4-gtkstyle breaks /etc/profile.env

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Franz Trischberger 2012-09-14 18:11:51 UTC]

sys-apps/portage-2.1.11.9
Today I updated to qt-4.8.3. After that cave fix-linkage errored out with

Error:
  * In program cave fix-linkage:
  * When loading broken linkage checker configuration for '/':
  * When reading '/etc/profile.env':
  * When parsing key=value-based configuration file '/etc/profile.env':
  * In file '/etc/profile.env': Bad variable at line 15 (paludis::ConfigFileError)

line 15 is
export GTK2_RC_FILES=$'HOME/.gtkrc-2.0'
After putting the "$" behind the quotation mark everything is okay, until I run env-update, which writes the broken line, again.

$ cat /etc/env.d/44qt4-gtkstyle
GTK2_RC_FILES="$HOME/.gtkrc-2.0"

Looks like a problem with files/44qt4-gtkstyle from x11-libs/qt-gui-4.8.3.

[Comment 2 Franz Trischberger 2012-09-15 06:37:52 UTC]

A-HA!
portage.util.env_update._env_update:

		if v.startswith('$') and not v.startswith('${'):
			outfile.write("export %s=$'%s'\n" % (k, v[1:]))

So changing the line in /etc/env.d/44qt4-gtkstyle to
GTK2_RC_FILES="${HOME}/.gtkrc-2.0"
fixes the issue...

And then I expect you will get:

$ echo "$GTK2_RC_FILES"
${HOME}/.gtkrc-2.0

instead of /home/sth/.gtkrc-2.0

which doesn't work as expected unless Gtk+ interprets '${HOME}' itself (I doubt it). As far as I know, interpolating shell variables inside env.d isn't allowed.

I was curious how it's done with variables like JAVAC which include a path inside user's home directory. Its done using files /etc/profile.d/java-config-2.{c,}sh (provided by dev-java/java-config). Not sure there's a better solution or not, but it looks interesting. Btw. I'm not a Qt maintainer, just sharing my thoughts…

Raising severity because this has visible (and really bad effects) to users.

[Comment 5 Ben de Groot (RETIRED) 2012-09-16 04:30:04 UTC]

OK, change reverted in qt-gui-4.8.3-r1
