[Libguestfs] [PATCH v2 nbdkit 0/5] tests: Move common functions into tests/functions.sh
v1 was here:
https://www.redhat.com/archives/libguestfs/2018-September/msg00057.html
v2:
- Fix tab vs spaces in configure.ac.
- To generate list of plugins, use printf instead of xargs.
- Use 'source ./functions.sh' instead of 'source functions'.
- functions.sh: Consistent quoting in foreach_plugin function.
- functions.sh: Change the contract of start_nbdkit so it requires
(and checks that) the first two parameters are '-P pidfile'. This
avoids needing to iterate over the arguments.
- functions.sh: Use {1..10} instead of seq.
- functions.sh: Add a common mechanism for handling traps / cleanups
(this is extra patch 4/5).
- functions.sh: start_nbdkit manages its own cleanup function for
killing nbdkit on exit

[Libguestfs] [PATCH v2 nbdkit 1/5] build: Move list of plugins and filters to the configure script.
It's easier to get it to other places if it starts out in the
configure script.
Also split the list into language and non-language plugins.

[Libguestfs] [PATCH v2 nbdkit 3/5] tests: Move common code for testing every plugin to tests/functions.sh.
This resurrects the unused tests/functions.sh file (although now we
need to generate it from tests/functions.sh.in). Put the common code
for running a test against every plugin here.
Because of the previous commits we can now use the plugins list
directly from configure.ac instead of needing to use weird shell
script, although we still need to preserve the test that the plugin
was built so that the tests continue to work if a plugin is disabled
or not built through missing dependencies.

Richard W.M. Jones

[Libguestfs] [PATCH v2 nbdkit 5/5] tests: Add a helper function which waits for nbdkit to start up.
This assumes bashisms, but bash is required to run the tests.
This is mostly refactoring. However the changes (simplifications) are
quite substantial:
- Since the new start_nbdkit helper function cleans up nbdkit on
exit, most scripts no longer need to deal with the pid or kill the
pid in the cleanup function.
- As a result, cleanup functions are radically simpler, and often
disappear completely.
- Also removed the comment "# The cleanup() function is called
implicitly on exit" passim partly because the cleanup functions
have mostly been removed and partly because it should be clear from
looking at functions.sh.
There is one additional change: In the test-memory*.sh tests, nbdkit
used to run in the foreground, but that seems to be a consequence of
some left over debugging. I changed it so they work like the other
tests.
