(Sorry for the long post. I need to explain a lot of things...)
This morning I had hard time in figuring out why my apache-perl fails to
start and I blame php4-interbase 4.3.8-1 for this. Please read on for
Since this morning my apache hangs on `apache-perlctl start' with two
processes (the master and one child) consuming all the CPU. Killing the
master is possible, but thi child is only killed by SIGKILL.
I started looking at my httpd.conf and it appeared that if I enable more
than one VirtualHost, apache-perl hangs as described. With only one
VirtualHost it starts ok.
However, the single VirtualHost I was trying is my web application that
uses IBPerl to connect to Firebird. Since this morning IBPerl croaks
that it is unable to complete the network request to "localhost" on
connect. I use classic and local database, so nothing is listening on
the loopback interface... I started debugging why IBPerl tries to make a
network connection while given a local file to connect to.
I was able to connect to local files using either isql-fb or pisql.pl -
an IBPerl implementation of isql. The problem remained only within my
So I decided to try connecting with ibwebadmin and it failed with the
same miserable error - "unable to complete network request to host
localhost". So I suspected this morning's upgrade og php4-interbase and
removed it (along with ibwebadmin, I'm afraid). Everithing runs fine
after this. I enabled all the VirtualHosts and there is no problem.
I see that php4-interbase depends on libfirebird2-super (>= 1.5.1-2) |
libfirebird2, which suggests that it is compiled against
libfirebird2-super and apache loads php4-interbase along with
libfbclient (the super library) and later refuses to load libfbembed,
which is needed for the local connections to work.
While I myself use classic, my roommate just installed super and he had
no problems whatsoever with IBPerl and php4-interbase.
My first thought was to recompile php4-interbase linked with libfbembed
(from libfirebird2-classic) to allow local connections too. And I did.
I recompiled php4-interbase with libfirebird2-classic installed. It
linked with -lgds (which is a symlink to libfbembed) and now everithing
works fine - both IBPerl and php4-intarbase can connect to local and
So far so good, but the resulting package is not installable on my
roommate's system, since it depends on libfirebird2-classic. :-(
I am quite sure that libfbembed (libfirebird2-classic) can work with
both local and remote connections, I am not sure whether it can
cooperate with local super-server. Even if it can, I can't find a way to
ling php4-interbase with lingds - ldd always shows libfbembed. So a
php4-interbase compiled with libfirebird2-classic will not work with
libfirebird2-super and vice versa.
Can you thing any way out of the situation? One is to provide two
packages - php4-interbase-(classic|super), but this is unnecessary
bloat. Both libfbembed (classic) and libfbclient (super) have the same
API, so in theory they are interchangeable. The only difference is that
libfbembed can connect locally.
Other possible solution is to link php4-interbase with libgds, but make
ld not resolve the link on link time, so ldd shall report libgds.0,
which shall link to the installed library (super or classic) on runtime.
I don't know whether this is possible though.
Third solution is to change libfirebird2-classic and libfirebird2-super
and make libgds.so hard link to the corresponding libfbembed or libfbclient.
What do you think? Whick solution is doable/best?
