ldap_start_tls(), ldap_install_tls() and async
by Frank Cusack
ldap_start_tls() is async, but ldap_install_tls() appears to send stuff
over the network. (I get errors on the server side about unknown protocol
if my client app does not call ldap_install_tls(), so I'm just guessing
that ldap_install_tls() sends network traffic.) So the problem is that
ldap_install_tls() is not async and does not accept a timeout parameter.
I guess that ldap_install_tls() does some crypto stuff as well, eg
obtaining random data which might block.
So doesn't ldap_install_tls() need to be async in order to make the start
tls operation as a whole async?
Or am I missing some information.
thanks

MSYS, Windows
by Howard Chu
Mostly off-topic, but may be of some interest...
I recently noticed while running the test suite on Windows with MSYS that the
server processes were not getting killed cleanly, they were just being
terminated abruptly. This tended to do weird things for subsequent tests,
showing complaints about not being able to delete the testrun directory for a
prior test because it wasn't empty. I found that one way to work around this
problem was to invoke Cygwin's "sync" command after each test. (Added into
tests/scripts/all.) In some cases it would cause a test to fail that would
otherwise succeed when run on its own.
But the actual problem is that the MSYS DLL doesn't propagate signals to
non-MSYS apps. And it turns out, I had actually noticed this back in 2003 and
subsequently forgotten.

Anyway, I've written a patch for the MSYS DLL which you can find here
http://sourceforge.net/tracker/index.php?func=detail&aid=1624635&group_id...
and I have a binary you can download here
http://highlandsun.com/hyc/msys-1.0.dll.gz
cksum: 2315022199 326195 msys-1.0.dll.gz
It's based off a recent pull from their CVS, so roughly version 1.0.11. It
also includes both of these patches
http://sourceforge.net/tracker/index.php?func=detail&aid=1174106&group_id...
If you're doing a lot of work with OpenLDAP in a Windows environment this
will definitely make life more tolerable.
