understood.  i'm exploring (non-production, yet) 'playing nice' with
apache worker mpm, reentrant mysql libs, and some threaded
functionality we're working on ...

fair nuf.

fwiw, given your comments, doing:

b4 config:

        perl -pi -e 's/mysqlclient\,/mysqlclient_r\,/g'
ext/pdo_mysql/config.m4
        perl -pi -e 's/mysqlclient\./mysqlclient_r\./g'
ext/pdo_mysql/config.m4
        perl -pi -e 's/libmysqlclient.lib/libmysqlclient_r.lib/g'
ext/mysql/mysql.mak
        perl -pi -e 's/LIBNAME=mysqlclient\n/LIBNAME=mysqlclient_r\n/g'
ext/mysql/config.m4

then:
        glibtoolize
        buildconf

and, after config, b4 make:

        perl -pi -e 's/mysqlclient /mysqlclient_r /g' Makefile
        perl -pi -e 's/mysqlclient\n/mysqlclient_r\n/g' Makefile

seems, so far to give me a stable/executable build, linked
uniquely/solely against lmysqlclient_r ... of course, i haven't done
any serious functional testing as yet.

let me know if/how i can play 'guinea pig' ...

The switch to enable thread safety is --enable-maintainer-zts.  The
name suggests though, that you shoulnd't use it unless you've got a
really good reason to do so.


Now about the reentrancy issues of the mysql extensions:
None of ext/mysql, ext/mysqli, ext/pdo_mysql check for the reentrant
version of the client library if ZTS is enabled.

ext/mysql though, calls mysql_thread_init() and mysql_thread_end() and
thus cause sort of a deadlock if linked against libmysqlclient_r.

Just a recap, no fix yet.

mike,

great. rather than dribbles of info, can you, then, please specify what
configuration option does and how to end up linked agaist only the
right/single library?

bottom line is i'm looking for thread-safe php + mysql, linked against
libmysqlclient_r.

let's just say the documentation hasn't been, at least for me,
forthcoming on the matter ...

This configure flag does not enable thread safety.

hi mike,

of course.

sorry, i should have specified rather than assumed it would be obvious
...

i have built php "--with-tsrm-pthreads".

same issue, one vs both libs linked.

>i've built mysql 5.0.21 threadsafe -- hence, the link target >needs to
be the _reentrant_ libmysqlclient_r

No. If you don't build a threaded client, you don't need to link
against the reentrant client libraries.
