Before executing the gnuplot executable the environment variable `GDFONTPATH`
is populated with a list of font directories, which is obtained from `fc-list`.
In that process we iterated over each line and called `dirname` on it, which
introduces a performance hit for loading and executing the external executable
`dirname` every time.
The new version avoids the loop.
The author of this patch measured a 42 fold performance improvement:
old version:
$ time ./gnuplot_old/bin/gnuplot -e ''
real 0m3.828s
user 0m0.392s
sys 0m0.465s
new version:
$ time ./gnuplot_new2/bin/gnuplot -e ''
real 0m0.091s
user 0m0.112s
sys 0m0.014s
The correctness of the value of `GDFONTPATH` was confirmed with the following
command and comparing its output between versions:
$ gnuplot -e 'print system("echo $GDFONTPATH")'

Configuring ghcjs-0.2.0...
Setup: At least the following dependencies are missing:
aeson >=0.7 && <0.10,
haskell-src-exts ==1.16.*,
optparse-applicative ==0.11.*,
syb >=0.4 && <0.6
This issue has been present for a while now, and it's only gotten worse.
This reverts commit 6353f580f90c0fdd2b418fa853a78ec508bda2a5.
Unfortunately cache=none doesn't work with all filesystem options.
Hydra tests error out with: file system may not support O_DIRECT

Broken since Aug 2015, but upstream has been dead for donkey's
years. Only dependent was systemtap. No reasonable way (or indeed
reason) to artificially keep this alive.
Aim for the head.
Silly ./configure, it looks for dbus file from gnome-shell in the
installation tree of the package it is configuring. Fix by copying the
needed file from gnome-shell before ./configure is run.
This change makes gnome-shell a build time dependency (not runtime).
This also changes the versioning scheme to be in more "human-meaningful"
terms, so instead of the internal release numbers we talk about 10.10.5
or 10.9.5.
