Bad symlink SAGE_DATA/graphs/graphs.db in binary distributions

Description
I downloaded the file sage-5.1-linux-64bit-ubuntu_12.04_lts-x86_64-Linux.tar.lzma from the official website. Sage was unable to use the graphs database.
An example of failure is (taken from the documentation):
Q = GraphQuery(display_cols=['graph6','num_vertices','degree_sequence'],num_edges=['<=',5],min_degree=1)
The file SAGE_DATA/graphs/graphs.db is a broken symlink to /tmp/graphs.db.cm5Li3EYGT. Replacing it with a link to graphs.db.orig fixed the problem.
From sage root directory:
$ cd data/graphs $ rm graphs.db $ ln -s graphs.db.orig graphs.db $ ls -l total 2452 lrwxrwxrwx 1 steven steven 14 Jul 26 14:35 graphs.db -> graphs.db.orig -rw-r--r-- 1 steven steven 1258496 May 20 2007 graphs.db.orig -rw-r--r-- 1 steven steven 1247018 Apr 4 21:56 isgci_sage.xml

Replying to leif:
I can confirm that random symbolic links are at least in all current binary dists for Linux...
On the other hand, I cannot reproduce this error (with Sage 5.2.rc0). I.e., sage -bdist
works for me w.r.t. this.

sage-bdist
looks sane as well, so that's probably a problem with the buildbot setup or other scripts not part of the Sage distribution itself.

Unfortunately this is still true for the new 5.2 binaries, at least all the Linux ones.

It's because of the buildbot setup.
This goes back to the Mitesh Patel days, which is sage-4.6 or something. So I don't understand why nobody ever noticed this before.

FWIW, some of the temporaries are kept as well:
leif@redhawk:~$ ls -l /tmp/graphs.db.* -rw------- 1 buildbot buildbot 1258496 2012-07-27 05:51 /tmp/graphs.db.Uc0awza1Zl -rw------- 1 buildbot buildbot 1258496 2012-07-27 02:01 /tmp/graphs.db.zX74CFVi9b
No idea why they're copied to /tmp
at all, since the database is fairly small.
At least the original files are also part of the bdists...

I agree it should be fixed, but I don't see why it should be a "blocker".

Because otherwise nobody notices this issue... ;-)

Fixed this on the buildbot and made one new binary: http://boxen.math.washington.edu/home/buildbot/binaries/sage/5.2.rc1/sage-5.2.rc1-linux-64bit-ubuntu_8.04.4_lts-x86_64-Linux.tar.gz
If this looks good, please set this to positive_review.

Well, the new bdist tarball looks sane w.r.t. graphs.db
(and I haven't found other references to temporary files), but I (so far) haven't tested the bdist itself, and I should probably review the change(s) to some script(s)...

The buildbot scripts aren't part of Sage, so I don't think these need to be reviewed. Anyway, the problem is fixed.

Haven't yet tracked this down.
