Public bug reported:
Adam just suggested the following:
infinity pitti: I'd suggest (since things like "try to rebuild the whole
archive" would be pointless) they their tests should consist of each one
triggering a rebuild test of the other two.
infinity pitti: If upgrading any of those three manages to keep the
testsuite of the others passing, that's a win.
infinity: i. e. the test script woudl more or less be "apt-get build-dep
binutils; apt-get source -b binutils", right?
infinity pitti: (This came up today after I just spent hours fixing a
regression in glibc due to the new gcc, and the inverse happens all the time
too)
infinity pitti: Yeahp.
infinity pitti: Oh, and linux-libc-dev (so, the linux source package)
should also trigger those three to a rebuild test, same reason.
infinity pitti: If linux-libc-dev's headers survive the GCC and glibc
testsuites, they're good enough for regular users. :P
infinity (And if they break regular users but not the toolchain, I'd
humbly suggest the users are wrong)
infinity Definitely would have been nice to know when gcc and the kernel
were uploaded (so, a couple of weeks ago) that they broke glibc, instead of
finding out today while I was uploading for other reasons.
infinity pitti: To cut down on the pain, we could potentially refine the
tests to do something like only build a single pass of libc6 and run the tests,
only build a single kernel, etc. Most of these things take so effin' long
cause they build 4 times.
