There are a number of issues with namespaces in AOLserver 3.x, which I believe
|
||
|
|
are fixed in 4.0, which should be released within a few months. But in the
|
||
|
|
meantime this is what we've had to do for AOLserver 3.2 on Windows 2000.

|
|
|
||
|
|
|
||
|
|
1. Under [ns_library shared] directory, create a directory called
|
||
|
|
packages.
|
||
|
|
|
||
|
|
2. Register this directory as a Tcl module in nsd.tcl:
|
||
|
|
ns_section "ns/server/${servername}/modules"
|
||
|
|
ns_param packages Tcl
|
||
|
|
|
||
|
|
3. Place each package into a subdirectory of the same name as the
|
||
|
|
package name (i.e. [ns_library shared]/packages/TclCurl)
|
||
|
|
|
||
|
|
4. Copy S:\NaviSoft\Server\modules\tcl\am\packages.init.tcl to the
|
||
|
|
[ns_library shared]/packages directory and rename to just init.tcl
|
||
|
|
|
||
|
|
5. Under AOLserver 4.x (and hopefully in 3.5.x) add to the bottom
|
||
|
|
of this file appropriate commands to register each package:
|
||
|
|
_am_pregister shared <packageName>
|
||
|
|
|
||
|
|
6. In your code, when you need to use a particular package, instead
|
||
|
|
of 'package require <packageName>', execute 'am_pinit <packageName>'
|
||
|
|
|
||
|
|
7. This will use the existing package registration under AOLserver
|
||
|
|
4.x and, under AOLserver 3.2, it will first register the package
|
||
|
|
in this interpreter and then use it.
|
||
|
|
|
||
|
|
8. This is necessary because in AOLserver 3.2, namespaces aren't
|
||
|
|
properly imported into child interpreters.
|
||
|
|
|
||
|
|
Currently dnscrub.com is set up like this for TclCurl and it works.
|
||
|
|
|
||
|
|
Example usage:
|
||
|
|
|
||
|
|
am_pinit TclCurl
|
||
|
|
curl::transfer -url http://am.net/index.htm -file d:/test.htm
|
||
|
|
|
||
|
|
FYI, the code for am_pinit and _am_pregister procs:
|
||
|
|
|
||
|
|
proc am_pinit {package} {
|
||
|
|
# AOLserver 3.2 package/namespace-handling is broken
|
||
|
|
# (namespace/packages don't get imported into child interpreters)
|
||
|
|
# so use this workaround proc instead of 'package require' to
|
||
|
|
# load the package into the current interpreter
|
||
|
|
# (this is obviously slower than copying from master interpeter)
|
||
|
|
# Package names are case-sensitive!
|
||
|
|
# Returns the version of the loaded package
|
||
|
|
set library shared
|
||
|
|
if {[lsearch -exact [package names] $package] == -1} {
|
||
|
|
ns_log Notice "packages: registering $library/$package"
|
||
|
|
_am_pregister $library $package
|
||
|
|
}
|
||
|
|
package require $package
|
||
|
|
}
|
||
|
|
|
||
|
|
proc _am_pregister {library package} {
|
||
|
|
# Registers the package. library is 'shared' or 'private'
|
||
|
|
set dir [ns_library $library]/packages/$package
|
||
|
|
source $dir/pkgIndex.tcl
|
||
|
|
}
