ns_internalredirect: expose Ns_ConnRedirect via Tcl command

Dossy Shiobara — Fri, 07 Oct 2005 00:44:05 -0000

To facilitate URL rewriting via Tcl/ADP, a new Tcl
command, "ns_internalredirect" is needed. This simply
exposes the existing Ns_ConnRedirect C function.

Improve const correctness

Markus Elfring — Sun, 07 Aug 2005 19:09:33 -0000

Would you like to apply the advices from the article
"http://en.wikipedia.org/wiki/Const_correctness" to
your sources?
I suggest to add the key word "const" to the type
specifiers for parameters like the following examples.

nscgi: SCRIPT_FILENAME, SERVER_ROOT, DOCUMENT_ROOT

Dossy Shiobara — Tue, 10 May 2005 01:16:33 -0000

Several environment variables aren't being set by nscgi:

SCRIPT_FILENAME, SERVER_ROOT, DOCUMENT_ROOT

In particular, SCRIPT_FILENAME is needed by "php-cgi"
for use under AOLserver with nscgi.

New Config APIs to document default values.

Tom Jackson — Wed, 16 Feb 2005 21:05:21 -0000

AOLserver uses a configuration file containing ns_section and
ns_param commands which are executed upon server startup.

The values obtained from the configuration file can override
default values which are set in the C files.

However, there is currently no method of easily documenting
what values are used, and what configuration options are
available without examining the C source files.

I propose adding new APIs which replace single lines of code in
the C source files where default values are stored in C
structures for later useage of the running server. Each new api
will attempt to append a new Ns_Set field to an existing set
associated with the section.

I have rewritten nsd/config.c and added four lines to include/ns.h
which provides the required APIs.

I have also written a C module and example config section for
testing the changes. The tar file contains the changed files and
the new module.

The files, along with diffs to 4.1a are located at
<http://rmadilo.com/m2/config-changes/>.

ns_adp_compress: apply gzip to outgoing ADP buffer

Dossy Shiobara — Mon, 10 Jan 2005 18:12:49 -0000

Using the new Ns_Compress() function, add the
capability to gzip-compress ADP responses.

New configuration options:

ns_section "ns/server/${servername}/adp/gzip"
ns_param enabled on
ns_param level 4
ns_param minsize 0

New Tcl API:

ns_adp_compress ?boolean?

By default, "boolean" is "on." Calling
"ns_adp_compress on" will flag the ADP request for
compression if the requirements are met (ADP streaming
not turned on, ADP reseponse is larger than minsize,
enabled in config).

Ship Tcl Threads Extension stock with AOLserver

Andrew Piskorski — Fri, 24 Dec 2004 05:10:52 -0000

The Tcl Threads Extension is compatible with and
inspired by the AOLserver NSV API, but is substantially
more featureful. So, why not just ship it stock with
AOLserver for 4.1?

Make ADP parser in 4.x backward compatible with 3.5.x

Jeremy Collins — Sun, 19 Sep 2004 06:49:37 -0000

The new default ADP fancy parser in AOLserver 4.x gives <% %>
tags precedence over registered tags. In rare instances this
behavior causes incompatibilities with ADPs written for AS 3.5.x,
so it would be nice if the old style was still supported.

Example of incompatibility with AS 3.5.x:

<% set foo 1 %>
<if foo eq 1>
<% ns_adp_puts bar %>
</if>

Output is:

<if foo eq 1>
bar

</if>

Clearly this fails to parse the registered tags.

The attached patch adds the 'backwardcompatible' ns_param to the
adp section of the configuration file. Setting this to true will revert
the adp parser back to AS 3.5.x style parsing.

Or even better would be to just drop the new style parsing and
leave it the way 3.5.x was! :)

[ns_info shutdownpending] is missing

Dossy Shiobara — Fri, 17 Sep 2004 14:10:35 -0000

The subcommand "shutdownpending" is missing from the
"ns_info" command. This should invoke the C API
Ns_InfoShutdownPending() and return a boolean value.

One specific use case where the [ns_info
shutdownpending] is important: long-running worker
threads running in forever-loops need to know when to
terminate at server shutdown. Especially important are
scheduled procs that run in separate threads from the
main "sched" thread.

Right now, those threads will cause the server to wait
until "shutdowntimeout" (default 20 sec) then the
server will abend with the following fatal message:

[17/Sep/2004:00:30:22][13849.79][-driver-] Fatal:
driver: trigger recv() failed: Socket operation on
non-socket

Those threads need to be implemented to periodically
check (at least as frequently as once every
shutdowntimeout seconds) for [ns_info shutdownpending]
true, and if so, terminate themselves.

For threads which run C procs, they should use the
Ns_InfoShutdownPending() C API which already exists to
do the same.

Integrate ns_image extension in core

Zoran Vasiljevic — Tue, 14 Sep 2004 06:55:21 -0000

There is an interesting and very useful extension nsimage
which effectively replaces the functionality of existing
ns_jpegsize and ns_gifsize built-in commands, adding
support for png images as well.

Idea is to integrate this into the core since it
effectively
adds more features, while providing the backwards
compat to existing commands.

Win32: Implement optional systray icon

Dossy Shiobara — Tue, 07 Sep 2004 14:13:25 -0000

On Win32, allow enabling of a systray icon from the
config .tcl script.

The systray icon might have several options: "stats" -
display some basic statistics (number of connections,
max connections, etc.); "control port" - open a simple
window which simulates the control port, taking input
and evaluating it and displaying the results; etc.
