I have noticed a problem with my program (which is supposed to generate
and receive many Posix signals ) and the function ldap_result(). It
happened to both my code and those library functions that used it (the
synchronous versions of various add/search/modify functions).
They all failed randomly with a "Can't contact LDAP server" error. I
tracked the issue down to the poll() function in os-ip.c : it's return
value is not checked to see if it has been interrupted by a signal.
Patching the library ( making the poll function to restart if errno ==
EINTR after failure ), resolved my problem.
Is it a bug or a choice? The patch is trivial, but if that error is not
checked by choice that should be documented imho.
I would send a question like this to firstname.lastname@example.org
And it would be ignored. This is the right list for this question.
But the original poster appears to be confused. ldap_int_poll() clearly checks
for EINTR already.
