I don't see anything that's obviously wrong in your code. (Well, there
isn't much code ;-)
Does the sample installation w/o changing anything (except maybe
settning webshroot correctly in websh.conf) work? What is the
output of using the sample as-is? Any logs in the Apache error log?
The poin twith the interpreters is: with
proc web::interpmap {file} {
# return interp class for request to file
return $file
}
you define which interpreter(s) handle which requests. The sample uses
2 defined interpreter classes (i.e. interpreterr that run the same
code for same set of requests) and all *.ws3 requests are handled by
their own class):
otherhandler.ws3: running requests to any file called other.html
htmlhandler.ws3: running requests to any *.html file (except the above)
*.ws3: each *.ws3 has it's own interpreter, which just runs the file itself
So the interpreter thing lets you decide which requests should be
handled by which code.
proc web::interpmap {file} {
return myCode.tcl
}
Would instead run every request through the same code no matter which
request is sent to mod_websh from the server (configured with the
AddHandler directive...)

Hi
Ok I finally compiled everything, I reinstalled Tcl so that .tcl was put in the extension
path.
Then I started experimenting with Websh again, I'm sorry if my questions seem to be kinda
stupid but the last time I ignored interpreters I got stuck.
I have the following problem(s)
When I try to visualize the configuration.html document it doesn't display full. I tried to
change the code in htmlhandler.ws3 to this
web::initializer {
web::config putxmarkup tag
}
restart the server but it ends up only working for only ONE time, then no more. Apache seems
to constantly crash and get back up on it's own. I remember having the same problems with
the older versions too.
If i change the following:
web::interpclasscfg "$webshroot/conf/htmlhandler.ws3" maxrequests 1
or to another number then my Vista keeps asking me either to close apache or to "find a solution"
for the program, Apache starts automatically up so it's kinda annoying..
I don't know what the heck is wrong, or how to use the interpreters or why they're needed,
where they're needed .. how to combine them cause it seems not to display my pages correctly.
I read the quick reference before but it took me lots of hours to figure out some things.
Could it be because I'm on vista? Even sessions seemed to work weird, and without a proper
interpreter I felt lost so I stopped using Websh.

Andrei

Hello
I have (successfully) compiled Websh before (with a lot of searching and work..) but now it
seems that i just can't compile the newer version. I'm using Tcl 8.6b1 and apache 2.2.14.
I tried using the compiled apache and also the uncompiled one but it just won't work.I always
get errors, sometimes the arp.h is missing, other times the libhttpd.lib is missing although
the libhttpd.dll exists.
Last time I tried to do everything i got this error:Microsoft (R) Program Maintenance Utility

Could you please be able to tell me how you did it precisely, cause i can't quite remember
how i made it work the last time. Do I have to compile Apache separated or do I need the TCL

Thanks in advance.
Hi Manu

Are you talking about Websh? If so, please update to the latest
version (3.6.0b5), where this issue is solved.
If that is not possible for some reason, you can overwrite the
_getCookie proc of a cookiecontext (where yourContext is changed to
the name of your context) as follows:
web::cookiecontext yourContext
proc yourContext::_getCookie {id} {
::set cookie [web::request HTTP_COOKIE]
foreach v [split $cookie ";"] {
# get key and value: note: some cookies (e.g.. Google analytics)
# also use = in the value, so a simple split with =; does
# not always work...
set key [string trim [lindex [split $v =] 0]]
set value [string trim [join [lrange [split $v =] 1 end] =]]
lappend kvlist $key $value
}
# search for $datatag
foreach {key value} $kvlist {
if {[string compare $key $id] == 0} {
return $value
}
}
error "no matching cookie found"
}
> Could you kindly tell me what did you do to solve this issue.
And if you don't talk about Websh: make sure whatever pareses your
cookies properly splits at "," characters and then just takes the
everything before the first "=" as cookie name, the rest as value,
even if it contains "0" aswell...

Hi Geroge > Can websh be used to create an HTTP REST service in tcl? Sure. But then, I guess you can create a REST service with just about every technology. Websh at least provides an easy interface to handle PATH_INFO and all parameters or form vars. That's abot what you need to create a REST service. > Ideally I want to have a thread pool (the one in the thread package) > with N threads already initialised. Can websh receive a request, place a > task in the thread pool and return the result? Well, I don't really know the thread package. Websh already provides an interpreter pool (when run as mod_websh) that you can use to handle mutliple requests per interpreter. It should not be a problem to use a thread package, as Websh is "just" an ordinary Tcl interpreter anyway. The only thing to onsider is making sure that you understand what your apache process model is and what you expect Websh to do, so that you scale where you actually plan it.

After fixing the logdest/close problem, the rest of the tests from 'make test' ran fine. I have not gotten around to running apachetest. It failed when I tried it because Ubuntu Apache does not have its configuration layout in the format expected by the test suite. I need to uninstall it and install a standard Apache distribution first and retry. Maybe today or tomorrow. /Ashok Ronnie Brunner wrote: >> It appears as though websh will crash if "logdest delete" is called on >> log destination that is a channel after closing the channel via Tcl's >> close command.

(apologies if duplicate - my previous email did not show up on the list) Ronnie, Regarding the "make test" crashes on Ubuntu - It appears as though websh will crash if "logdest delete" is called on log destination that is a channel after closing the channel via Tcl's close command. In particular, test log-2.6 has the following sequence: close $fh web::logdest delete This results eventually in a call to Tcl_Flush from destroyLogToChannelData with a channel pointer that is no longer valid. The end-result is likely to be random crashes as Tcl_Flush does not seem to do any validation. Please verify if that might the problem. Of course, that may or may not be the cause of the crashes you are seeing. Funnily enough on XP and Tcl 8.6 the test suite runs fine. I suppose it depends when that memory gets reused.

Yeah, I guess it's about time to release at least 3.6.0b5. Unfortunately, I was reproved by Apache for releasing anything without following the proper ASF rules. It's about time I find out how to do it properly, I guess ;-) (Just using some "-SNAPSHOT" version does not really solve the problem of knowing what code is in use, it just makes sure that you don't mix up the released version with any other build... I'll try to think of something.) > Finally two questions, on both Windows and *ix, does mod_websh need to > be built differently based on the Apache process model (MPM etc.) ? How > about whether the Tcl binaries are built threaded or not ? No, mod_websh does not care about MPMs or threads in Tcl (i.e. you don't have to change anything when building). Websh itself is thread safe. But it certainly makes difference when it's run in different environments: - If Apache runs in any threaded MPM, Tcl Must be threaded as well. - CGI case is independent of the model (for obvious reasonsn ;-) - If your Websh app uses threads: Tcl must be threaded too, regardless of the MPM Apache runs - Interpreter handling is different when running in threaded vs. non-threaded MPMs: For every (Apache) process there is an interpreter pool. While requests can share interpreters within a process, they cannot do so across processes. (For example this needs to be considered when you try to create sessions kept in memory of the Apache process, which only works properly if you run Apache in a single process mode.)

I guess that depends on how familiar you with it... We've done dome
pretty serious things and usually we get somewhere within a few
hours. But I'm certainly aware that there is some effort needed to get
into Websh.

The basic idea is that you have an interpreter class that contains all
common code so that you only put in a specific page what you actually
want to have there. In your setup, I'd expect auth.ws3 (and some stuff
to abstract html in the common code, while index.ws3 probably just
renders the index page. Sonething like:
index.ws3:
if {[isAuthorized]} {
page "Your title" {
navigation "My Entry"
title {Here it comes}
p {Foo bar zoo}
}
}
While [isAuthorized] renders a login page if not authorized.
In such a setup you don't really need web::dispatch.
web::dispatch I'd setup to be used in something like admin.ws3, where
you have a couple of commands needing to be handled, so that admin.ws3
acts like an app itself.
> Or can you

Sure: as long as the session handling code is in the common code,
e.g. using a cookie context that refers to a session using a cookie,
so you don't have to put anything in the URL (though nothing keeps you
from doing this).

This should be answered by the above explanation. Maybe the additional
hint helps:
in websh.conf, use
proc web::interpmap {file} {
return /path-to-your/wrapper
}
web::interpclasscfg /path-to-your/wrapper maxrequests 0
your wrapper looks like:
# only source the code on the first request
web::initializer {
web::include /path-to-your/common-code
}
# process the actual web page
web::include "[web::config script]"
and your common-code contains all your shared code used in the various
pages like index.ws3, register.ws3 etc.

First of all I would like to congratulate you guys for your efforts WebSh.. it's a good alternative..
BUT
It takes a lot of time to develop something serious.. You get lots of errors and have to debug
it like no other...
I spent a few hours compiling the mod_websh with xampp to find out later on that Apache provides
a easy binary of Apache...
The
past 3 days I spent more than 20 hours in total to make a pathetic
Register, Login, Request Password and template file..... It wouldn't
have taken more than a few hours to make it in PHP! (well.. debugging +
sql testing..)
And I still have problems with it .. I'm thinking of
deleting it and every file i used for WebSh on my computer because of
the time I lost trying to figure out a few simple things ...
I read all the documentation, went through all the examples And i have a few
questions(well,a lot more but i'll put some examples later`}
The
web::dispatch thing is very good when you have 1 file.. But what do I
do when i've got 3 files and I need to communicate one with another?
Send data and stuff... Because I made a something with web::include...
and even altered the web::cmdurlcfg -scriptname ...
How can you use
the sessions so you ACTUALLY send it from one page(file) to another.. i
tried almost everything.. and nothing worked...
Or can you
make it so that once you set a session you can get it back in every
file you access? (Just like php, not only through links)
How
should I access those multiple files if i need them? How should I
rescript my script in order to work that way.. (clearly: i go to my
site, i see index.ws3 that includes auth.ws3 then i chose a link to
register, .. the form & settings go on.. Registration is succesful,
i look in my database and it works, then i login succesfully.. and then
the problems come... sessions work only on the first page after the
login (map.ws3) but only a part there.. for the rest i get some weird
problems, sometimes a few procs don't work..)
Thanks in advance...
P.S. Any motives in WHY i should still use WebSh? Cause i already spent a lot of time in learning
it...
If you have some extra examples you guys could show me.. i would be very happy to learn out
of them..

for us developers with a daytime job? ;-)
The new paragraphs from the (committed, but unpublished) quick
reference (request_data_handling.html):
""Special case for handling Basic Auth:
web::request AUTH_USER
returns the username provided by the user when Basic Auth is
requested and Apache does not handle it (i.e. if Apache does not
provide REMOTE_USER).
web::request AUTH_PW
returns the password provided by the user when Basic Auth is
requested and Apache does not handle it (i.e. if Apache does not
provide REMOTE_USER).
The following example provides a basic app that requires Basic Auth
and completely bypasses Apache's auth mechanisms.
Example 7. web::request AUTH_USER and web::request AUTH_PW
# returns 1 if user/pass provided is websh/websh
proc isAuthenticated {} {
if {[web::request -count AUTH_USER]} {
set user [web::request AUTH_USER]
set pass [web::request AUTH_PW]
if {[string eq $user "websh"] && [string eq $pass "websh"]} {
return 1
}
}
return 0
}
# the default command requests Basic Auth unless provided correctly
web::command default {
if {![isAuthenticated]} {
web::response -set Status {401 Authorization Required}
web::response -set WWW-Authenticate {Basic realm="Websh auth"}
web::put "Sorry, you're out"
} else {
web::put "You're in"
}
}
# command dispath
web::dispatch
Note: CGI usually does not expose the Basic Auth Authorization header
for security reasons. The following configuration for Apache (as of
version 2.0.51) will allow Websh to also provide the same
functionality when running in CGI (requires mod_setenvif):
Example 8. Apache configuration for AUTH_USER and AUTH_PW to work
under CGI
SetEnvIf Authorization "^(Basic .+)$" AUTH_BASIC=$1
Important security consideration: This configuration will also expose
the authentication information to Websh when Apache does handle the
authentication. Although Websh hides the information in that case it
is always available in the CGI environment. Use this Configuration
carefully.""
If you ever find the time to play around with this let me know if it
works for you.
Best regards
Ronnie

Sure I remember. I actually have some uncommitted code lying around, but
I never really made it work properly. If you accidentially followed my

As I wrote above: Plan: yes. Any time soon? I can't promise
anything. I have another thing I want to commit first: load
libwebsh.so/websh.dll from websh/websh.exe and mod_websh.so instead of
statically linking the same object code to the various targets. (No
functional change, but just a cleaner way to deploy, as the compiled
code installed only once.) When this is done: I'll give it another
try.

Hi Ronny,
some time ago (Apr 2006) we had a discussion on how to add access to user/password from the
authentication of APACHE.
Today I installed websh on a new server (upgrading to APACHE 2.2.10).
I had some problems, which basically resulted from using
web::response -httpresponse "HTTP/1.x 401"
which worked fine with APACHE 2.0. Now it needs to be
web::response -httpresponse "HTTP/1.0 401 Unauthorized"
otherwise the response status will not make it to the browser. Instead "HTTP/1.0 200 OK" is
sent, which is not triggering the user/password dialog in the browser.
This seems to be in the APACHE part, at least I did not see anything in websh to do this.

For this new installation I decided to use the newest version from SVN, also because there
were some bugfixes with response and APACHE 2.2 reported. I sadly recognized, that the changes
were not in (yet). Any plans to do so?
However, I integrated your patch for 2.0 and it again works like a charm for me.

A server is allowed to send multiple Set-Cookie headers (one for each cookie with different expirations etc.) However websh does not seem to allow this. Using "web::response -set Set-Cookie COOKIEDATA" multiple times results in only the last call being in effect (i.e. only one Set-Cookie line with the contents of the last call are sent to the client). Any way to work around this? If you can point me to the approximate place to look at modifying this behaviour, I can take a stab. As an aside, I cannot use cookiecontext type mechanisms as the cookies set have to be readable by other server-side non-websh components.

There's no impact on memory as you have an interpclass for every
script you use anyway. The only impact is that you call
web::interpclasscfg way too often. It is not really an expensive call
though, but it needs an additional lock on some internal resource and
locks can be bottlenecks. I can't tell you however whether this is
worse than creating the overhead of tracking the files you already
have configured:
if {[string match *.html $file]} {
set script [file join [file dirname $file] htmlhandler.ws3]
if {![info exists pool($script)]} {
web::interpclasscfg $script maxrequests 10
set pool($script) 1
}
return $script
}
This takes a bit more memory (the pool array) but as I said: don't
know if it actually makes a difference. Could be even slower...

Not sure what impact that might have on memory (separate interpclass

I'm playing around with using namespaces and slaves to reduce the time
to deliver a web page by making the interpreter handle multiple
requests. The websh.conf file has the lines
# individual scripts (each with its own interpreters)
if {[string match *.ws3 $file]} {
return $file
}
in the web::interpmap command. The question is, not how do I write the
corresponding web::interpclasscfg command to change maxrequests to (say)
10 ? interpmap takes the class name as a parameter but since that
changes on a per file basis, how do I change it? The ws3 files may lie
in different directories so I don't want to hardcode or enumerate full
paths if possible.
A somewhat related question is that I want the html handler to be
specific to the directory that the html file lives in. So I've modified
the html handler fragment in web::interpmap in websh.conf to be
# default html content (html that contains snipplets only)
# all requests for *.html files share interpreters
if {[string match *.html $file]} {
return [file join [file dirname $file] htmlhandler.ws3]
}
Again, I have the same question, how do I now configure interpclasscfg
for each to change the maxrequests without having to list out each
possible directory as a separate class ? (maxrequests will be same for all)
Any solutions ?
Thanks

No. I'd call it a bug. Depending on Browser and Web server the
HTTP_HOST is sometimes with port and sometimes without. That used to
be more often without port... (when the Websh code was written.)
I'll put it on the bug list. Work around it by using something like
web::cmdurlcfg -host localhost

Please use websh-user@tcl.apache.org for this type of question. To compile and install Websh on Windows, you need to install Tcl first. Use (for example) an ActiveTcl binary distribution (from http://www.activestate.com/Products/activetcl/index.mhtml) Make sure that Apache is installed. Get it from http://httpd.apache.org/download.cgi Then, get Websh (available in source only). Preferrably, use the latest version from Subversion, not the last build available. You can get the latest source using an SVN client from http://svn.apache.org/repos/asf/tcl/websh/trunk/ To comile and install Websh, you need to have an MS Visual Visual Studio 6.0 (or higher) nmake utility. Follow the instructions in src\win\README (http://svn.apache.org/repos/asf/tcl/websh/trunk/src/win/README) To run Websh, either just use websh.exe to run Websh CGI scripts or configure Apache to use mod_websh.so (which is created by compiling Websh, not Apache HTTPD). Follow the README.txt found in your installation directory or the source directory doc\mod_websh\README or online http://svn.apache.org/repos/asf/tcl/websh/trunk/doc/mod_websh/README hth Ronnie -- Netcetera goes mobile - travel in Zürich with our free iPhone application: http://mobile.netcetera.ch/tramdroid Ronnie Brunner | ronnie.brunner@netcetera.ch phone +41-44-247 79 79 | fax +41-44-247 70 75 Netcetera AG | 8040 Zürich | Switzerland | http://netcetera.ch --------------------------------------------------------------------- To unsubscribe, e-mail: websh-user-unsubscribe@tcl.apache.org For additional commands, e-mail: websh-user-help@tcl.apache.org

Ronnie, > But I understood you wanted to have Websh on the web server side > and write something that renders a Tk GUI in the browser... Exactly. I have a third-party application (a WYSIWYG editor, GUI included) which is already developed in TCL/TK, and I want to run it as a web application over Apache2/Win32. The live examples in the webpage (i.e. http://tcl.apache.org/websh/examples/memory.ws3) made me think Websh could be the solution, but if it won't allow me to embed a TK GUI, it isn't the right tool to accomplish this. Maybe I could look into compiling the TCL/TK script into something that can be embedded into a HTML web page. But I don't know what to look for. In a matter of fact, I don't even know if that's possible... any ideas you may have, I'll be happy to hear :) Thanks for your help, I really appreciate it.

Hi > I couldn't find any documentation covering this in the webpage. Could you > please tell me how to adapt a pure TCL/TK script to run in Websh? If you have a plain Tcl sricpt that works in a CGI environment, it will also work as-is in Websh. Websh just adds lots of functionality regarding request handling and other web related stuff. However Tk scripts are not compatible at all: Tk is a client GUI framework and your cannot really use it in Websh at all. (Well that's not quite true: as Websh is basically just an extended Tcl shell, it could also be used to write a client app with a Tk GUI. But I understood you wanted to have Websh on the web server side and write something that renders a Tk GUI in the browser...) If you want to build an ajax based rich web application, you might want to consider looking at Aejaks (http://aejaks.sourceforge.net), which is a Tcl ajax framework that borrows much from Tk (but is not compatible either...) hth Ronnie -- Ronnie Brunner | ronnie.brunner@netcetera.ch phone +41-44-247 79 79 | fax +41-44-247 70 75 Netcetera AG | 8040 Zürich | Switzerland | http://netcetera.ch --------------------------------------------------------------------- To unsubscribe, e-mail: websh-user-unsubscribe@tcl.apache.org For additional commands, e-mail: websh-user-help@tcl.apache.org
Hi, I was looking for a way to run a TCL/TK script in a web environment, and I ran into Websh. But when I tried to run my script, I realised that I had to change several things of the original TCL/TK script for it to run in Websh. I couldn't find any documentation covering this in the webpage. Could you please tell me how to adapt a pure TCL/TK script to run in Websh? Thanks in advance, Ricardo
