Hi,
when building PHP using
(I) ./configure --with-mysql --with-mysqli --with-pdo-mysql
you currently get a build using the system default libmysql, usually
in /us or
such. Alternatively PHP can be built using
(II) ./configure --with-mysqli=mysqlnd [...]
to build the MySQL extensions using the mysqlnd library.
I would like to change mysqlnd's config9.m4 file to build PHP using
mysqlnd when being called in form (I). Users would still be able to
enforce libmysql by passing a path, like /usr.
There are two main reasons I see for this:
a) Different libmysql versions have slightly different behavior,
which shows in our tests. We can't have both, a good test coverage
and cover all these differences. By using mysqlnd we have a clear
behavior every PHP developer can rely on.
b) We provide different extensions (pecl/mysqlnd_*) which
improve/extend mysqlnd functionality. By having mysqlnd as default
these are better usable by users.
Opinions?
