In tests, give Ganeti enough time to actually start up jobs before
asserting that they succeed. While normally forking and executing
a job is finished in less than a second in some circumstances it
can take longer; so give enough time to avoid flaky tests.

While there, also pause the watcher, so that it doesn't submit
jobs inbetween that cause our 0.01 second delay jobs to take
longer while waiting for locks taken by the watcher's jobs.

This test verifies a global limit on the number of jobs running. This
requires knowledge of all jobs submitted between the addition of the
filter and the submission of our last test job. While we send these
commands directly one after the other, this still takes a second or
two, thus giving the watcher slightly less than a 1% change of
interfering. Avoid this by pausing the watcher during this test.

The test submits 3 jobs in an environment rate-limited to two, and verifies
that the first 2 jobs are running whereas the third one remains queued. However,
it takes for Ganeti some time to get a submitted job to actually being confirmed
waiting (in some circumstances over a second). So wait a bit longer to avoid
losing the race. While there, increase the time of the delay jobs to avoid
them finishing during that test in an extremely slowly running QA. (Note that
the jobs are killed forcefully at the end of the test, so that time is never
really waited for.)

Currently, the 'gluster' and 'sharedfile' disk templates are both mapped
to the Shared File storage type. This compromise causes the Gluster block
devices to be interpreted in the config as 'sharedfile' devices, instead
of 'gluster', and subsequently to be wrongly handled as Shared File
disks. This behavior, currently makes the 'gluster' disk template not
functional.

This patch, fixes this issue by introducing the Gluster storage type,
which will be exclusively used by the 'gluster' disk template.

With Ganeti imposing no requirement on Xen versions, the configuration
file that should be present varies greatly on the choice of toolstack
and Xen version. xend-config.sxp was considered obligatory, but in
higher versions and with xl, it is superseded by xl.conf and considered
deprecated. This patch makes it have the same status as xl.conf - Ganeti
will distribute it but not require its presence.

to ensure we are not reporting stray volumes on other VGs as orphans.
Signed-off-by: Hrvoje Ribicic <riba@google.com>
Reviewed-by: Klaus Aehlig <aehlig@google.com>

Prior to patch eeda5882, Ganeti checked all the LVs on nodes under
its control, and dutifuly declared any stray volumes as orphans in
warnings emitted during cluster-verify. After the patch, the nodes
returned information related only to the LV set as *the* Ganeti VG,
bypassing this problem.

Unfortunately, this led Ganeti to report the disks of instances created
on a different VG as non-existent. This patch fixes things by reverting
patch eeda5882 and making Ganeti warn about orphan volumes only if
they belong to the Ganeti-administered VG.

When opening domain sockets for communication, the Haskell daemons did
not set any permissions for the sockets, defaulting to 0700. This was
fine when all of them ran as root, but was bound to cause trouble in a
split-user setup. The first issue is RAPI access after master-failover,
where RAPI could not send make any inquiries until the watcher restored
the desired permissions of the socket.

This patch modifies Luxid to use a g+rw socket, and leaves other servers
to their default of 0600.

It turns out that GHC 7.8's -dynamic-too is forbidden not only for
profiling builds object files, but also for those using HPC coverage.

This commit accordingly renames HFLAGS_NOPROF to HFLAGS_DYNAMIC
(since it now is not conditional on profiling any more),
and makes sure that it is not used for profiling or HPC.

This way we achieve that, for profiling+coverage builds
  - .dyn_o files are available for use in TH in the following 3 cases
  - .o files are for the normal binaries
  - .hpc_o files are for coverage-enabled test binaries
  - .prof_o files are for profiling binaries

We make .hpc_o files depend on the .o files because the creation of
the .o files will also create the .so files needed for TH.
This was already in place for .prof_o files.

This requires that HFLAGS now also contains `-itest/hs` since
the rule for .o files is now also responsible for building .o/.so files
in test/hs.

It changes `-osuf .ext` to `-osuf ext`; the old form was allowed in
GHC <= 7.6, but GHC 7.8 seems to have problems with it:
  https://ghc.haskell.org/trac/ghc/ticket/9760

The form without dot works in all GHC versions, and we don't have
dots in other -osuf arguments in the same file either, so this
was probably an accident.

GHC 7.8 switched to dynamic linking being used for ghci, which requires
that .so file are being built for modules that are loaded for TH.

For this reason, GHC >= 7.8 has a -dynamic-too flag, which we now use.

However, -dynamic-too must not be enabled for profiling builds,
which is why this commit introduces a HFLAGS_NOPROF variable
(currently only containing -dynamic-too) that must be passed to
all GHC invocations that are not creating profiling output.

GHC 7.8 (undocumentedly) changed the way in which ghc -M generated
object file dependencies, lacking the underscore that older versions
added automatically to the file names.
It also requires a -dep-suffix for the plain object file (.o).

This commit detects GHC 7.6 and older (7.7 is development only, has no
release and is treated equal to 7.8), and adjusts the -M invocation
appropriately for newer GHC versions.
