The default behaviour of fopen() when called on a named pipe which does not have any reader, is to block, until a reader opens the pipe. This blocks slapo-auditlog when it attempts to write output. Depending on how critical the audit log is, it may be preferable to discard audit log output and continue processing requests if there's no reader available.
For clarity the call to fopen() is removed and replaced with open()/fdopen(), allowing us to specify O_* flags as opposed to using fopen() or open()/fdopen(). 0666 are the base permissions used by fopen() when files are created.
This uses the result AC_CANONICAL_HOST and a pre-existing case statement checking for mingw32, cygwin, interix to determine if the build system is Windows based... We make the not unreasonable assumption that if the build system is Windows based, the tests will also be running on a Windows system.
Streamline configuration of slapd modules. Just use the
appropriate OL_ARG_ENABLE_xx, then almost no other edits
will be needed in configure.ac when adding new modules.
Backends will still have to add their Makefile to the
AC_CONFIG_FILES() list.
When identity assertion is not done (e.g. cn=People which is Bjorn's
direct backend) we need to store the client's password to bind as them
but that only works if they did a simple bind. Might be enabled again if
identity assertion rules change in the future.
For simple (non-nested) member compares, avoid unnecessary fetches
of dyngroups that can't match the filter.
cache filter/entry instance info across multiple dyn entries to
avoid refetching each filter entry for each dyngruop test.
Minimize cost of dynamic lists while still making them filterable:
require their attrs to be explicitly mapped if filtering is to be supported.
Also check config scope in compare op
Some values we export in cn=monitor are not managed in a single place,
instead, a task exists that gathers a snapshot of the lloadd state and
stores it for monitor consumption. This exposes a race between the test
reading it out and lloadd updating this cached copy. While we still have
to rely on a shell, rather than being intelligent about whether or not
we should emit a readout into search.out or wait and try again (which is
what test004-monitor does), just filter this attribute out.
