Package: electric-fence
Version: 2.0.5-4
Severity: wishlist
I have a program with a regression test suite; the tests include
checks that the program's stderr output is as expected.
Unfortunately, I can't test the program properly when linked with the
current version of Electric Fence because it fails all the tests - the
banner message causes the test harness to think the test program has
failed (or at least misbehaved) !
Please find below a patch which remedies this problem. It provides a
new global external variable / environment variable
EF_DISABLE_BANNER. This is documented, with a warning about the
risks of setting it (particularly as a variable).
I changed the debian/changelog (so that it would build well and
install on my system), but I didn't change the CHANGES file.
Bruce: the current Debian package lists your Pixar address in the
upstream tarfile. Does this still work ? I've also tried a
half-remembered hams.com address.
Ian.

+EF_DISABLE_BANNER
+This is an integer which if nonzero specifies that the usual Electric
+Fence banner and copyright notice should not be printed. This is
+provided for certain circumstances where the banner can be annoying
+(eg, running a regression test suite that also monitors stderr). Note
+that you should almost certainly not set this in your program, because
+then you might leave Electric Fence linked into the production
+version, which would be very bad.
