Solution: revert DRAFT -> STABLE API transition so that we can do a
bugfix-only 4.2.5 release.
Will be re-reverted once tagged.
Revert "Problem: ZMQ_BINDTODEVICE has met STABLE conditions"
This reverts commit 3cb79f5042.
Revert "Problem: ZMQ_MSG_GSSAPI_* have met STABLE conditions"
This reverts commit 374da4207b.
Revert "Problem: ZMQ_MSG_T_SIZE has met STABLE conditions"
This reverts commit 6411c4a247.
Revert "Problem: docs say STABLE API still in DRAFT"
This reverts commit 9f2f30b7ff.
Solution: do it to avoid leaks. Even though they are below 33 bytes so
it's all allocated on the stack, the small message size might change in
the future.
Solution: use ZMQ_LAST_ENDPOINT in most places. This alllows running
tests in paralle, and on over-booked shared machines where many of
the ports would be already in use.
Keep 3 tests with an hardcoded port, as there are some code paths that
require it (eg: connect before bind), but list those ports in
tests/testutil.hpp as macros so that they do not overlap and still
allow parallel runs.
These changes were inspired by a patch uploaded to Ubuntu by the
package maintainer, Steve Langasek <steve.langasek@ubuntu.com>.
Thank you Steve!
Problem: there is no test coverage for GSSAPI.
Solution: add a test structured like the CURVE test.
The test is not built if libzmq is not configured with
--with-libgssapi_krb5. It will report SKIPPED status
if the required environment is missing (see below).
Environment: KRB5_KTNAME and KRB5_CLIENT_KTNAME
environment variables must point to a keytab file
containing creds for a host-based test principal
(see comment at top of source for details).
Kerberos must be configured and a KDC containing the
test principal must be running, otherwise the test
will fail/hang.
N.B. For now, the test must use the same principal for
both client and server roles because it seems impossible
to set them to different principals when they are
threads in the same process. Once one principal is
cached in credential cache, attempts to acquire creds
for a different "desired name" seem to be ignored and
the cached principal is used instead.
