#60 Allow explicitly setting shared library path in config

[Stephen]

This patch adds a new option to the config file:

ns_section "ns/parameters"
ns_param sharedlibrary ${nshome}/modules/tcl

This defaults to ns/parameters/home with modules/tcl
appended, which is inconvenient if you want to set the
home directory for a server some where other than your
AOLserver installation.

Patch to add ns/parameters/sharedlibrary config option

Is this all that is needed? I can hardly believe.

What about other modules? On Linux, if you have
/usr/local/aolserver installed, the nsd will always pull
shared libs
(libnsd.so for example) from there regardless of the
LD_LIBRARY_PATH setting. I can't imagine that you can easily
change the homedir that easily but I'm willing to learn .)

Now, again, is this all that's needed. IOW, can you give an
example what do you exactly mean by:
"set the home directory for a server some where other"

Sorry, I should have explained more clearly.

By 'home directory' I mean the setting:

ns_section "ns/parameters"
ns_param home /usr/local/aolserver

AOLserver CDs to this home directory on startup, and that
seems to be the default location for incomplete file uploads
to be dumped, which is *really* inconvenient.

Another issues is one of packaging -- I like to put binaries
in /usr/bin, log files under /var, websites somewhere else...

You can of course change ns/parameters/home, but then
AOLserver can't find the core Tcl modules (init.tcl,
file.tcl, form.tcl etc.). This patch fixes that.

I guess another approach would be to look at why file
uploads end up in the home directory, perhaps force them
into /tmp. But /tmp is often a different partition, so to
save needless copying I'd prefer to keep them where the rest
of the files live.

The supplied patch seems like a simple, easy way to fix it...

Thanks.

What about:

nsconf.tcl.sharedlibrary =
Ns_ConfigGetValue(NS_CONFIG_PARAMETERS, "sharedlibrary");

if (nsconf.tcl.sharedlibrary == NULL) {
Ns_HomePath(&ds, "modules", "tcl", NULL);
nsconf.tcl.sharedlibrary = Ns_DStringExport(&ds);
} else if (Ns_PathIsAbsolute(nsconf.tcl.sharedlibrary) == NS_FALSE) {
Ns_HomePath(&ds, nsconf.tcl.sharedlibrary, NULL);
nsconf.tcl.sharedlibrary = Ns_DStringExport(&ds);
}

This way you can even change the layout of the structure
underneath the home. We should examine wether this
is the only place things get hard-wired and eventually
modify all those with constructs as above. This will then
allow you to make an installation layout of your choice.
What do you think?
