# commit b4dd15b
# BUG/MINOR: unix: Make sure we can transfer abns sockets on seamless reload.
#
# When checking if a socket we got from the parent is suitable for a listener,
# we just checked that the path matched sockname.tmp, however this is
# unsuitable for abns sockets, where we don't have to create a temporary
# file and rename it later.
# To detect that, check that the first character of the sun_path is 0 for
# both, and if so, that &sun_path[1] is the same too.

REGTEST/MINOR: skip seamless-reload test with abns socket on freebsd abns sockets are not available on freebsd as such mark the test to skip this OS and expose-fd was implemented first in 1.8 so require that

# abns@ sockets are not available on freebsd
REGTEST: exclude OSX and generic targets from abns_socket.vtc This one relies on Linux's abstract namespace sockets which are not available there. FreeBSD used to already be excluded.

REGTEST: replace LEVEL option by a more human readable one. This patch replaces LEVEL variable by REGTESTS_TYPES variable which is more mnemonic and human readable. It is uses as a filter to run the reg tests scripts where a commented #REGTEST_TYPE may be defined to designate their types. Running the following command: $ REGTESTS_TYPES=slow,default will start all the reg tests where REGTEST_TYPE is defines as 'slow' or 'default'. Note that 'default' is also the default value of REGTEST_TYPE when not specified dedicated to run all the current h*.vtc files. When REGTESTS_TYPES is not specified there is no filter at all. All the tests are run. This patches also defines REGTEST_TYPE with 'slow' value for all the s*.vtc files, 'bug' value for al the b*.vtc files, 'broken' value for all the k*.vtc files.

REGTEST: increase timeouts on the seamless-reload test The abns_socket in seamless-reload regtest regularly fails in Travis-CI on smaller machines only (typically the ppc64le and sometimes s390x). The error always reports an incomplete HTTP header as seen from the client. And this can occasionally be reproduced on the minicloud ppc64le image when setting a huge file descriptors limit (1 million). What happens in fact is the following: depending on the binding order, some connections from the client might reach the TCP listener on the old instance and be forwarded to the ABNS listener of the second instance just being prepared to start up. But due to the huge number of FDs, setting them up takes slightly more time and the 20ms server timeout may expire before the new instance finishes its startup. This can result in an occasional 504, except that since the client timeout is the same as the server timeout, both sides are closed at the same time and the client doesn't receive the 504. In addition a second problem plugs onto this: by default http-reuse is enabled. Some requests being forwarded to the older instance will be sent over an already established connection. But the CPU used by the starting process using many FDs will be taken away from the older process, whose abns listener will not see a request for more than 20ms, and will decide to kill the idle client connection. At the same moment the TCP proxy forwards a request over this closing connection, it detects the close and silently closes the other side to let the client retry, which is detected by the vtest client as another case of empty header. This is easier to reproduce in VMs with few CPUs (2 or less) and some noisy neighbors such as a few spinning loops in background. Let's just increase this tests' timeout to avoid this. While a few ms are close to the scheduler's granularity, this test is never supposed to trigger the timeouts so it's safe to go higher without impacts on the test execution time. At one second the problem seems impossible to reproduce on the minicloud VMs.
