tclhttpd-users — Discussion and general Q&A for TclHttpd

[Tclhttpd-users] tclhttpd3.3 tcllib issue

[Steve B. <st...@pr...>]

I noticed some traffic on clt regarding the package require tcllib0.7
in bin/httpd.tcl.   I get a different message, which comes from the
error branch (line 104 or thereabouts).

At the moment, I'm progressing by simply commenting the line out, and
I haven't so far hit a problem.   But I'd like to know whether it
*actually* matters.

I'm in the process of building and testing tclhttpd wrapped as a
scripted document for use on a customer's site with tclkit, and will
be working through the traffic on the list to look for other bugs and
patches.   Is a bugfix release planned?

Re: [Tclhttpd-users] Does tclhttpd run as an NT (actually Windows 2k) service?

[Ralf W. <a52...@gm...>]

Hi,

I've done it for NT and Windows 2000 and tclsvc works quite well for
tclhhtpd, beside a usually slow resonse when shutting down the service.

As I did not want to interfere with or rely on an already existing
Tcl/Tk installation, I added two new registry keys (Tcl_library and
Tcl_PkgPath) and modified the service wrapper to set the paths for the
Tcl Library and the Tcl Package Path if these registry keys are present.

You should be able to use the standard service wrapper in combination
with a standard tcl installation to run tclhttpd as a service. Remember
to disable the "vwait forever" in httpd.tcl using:

    if {![info exists tcl_service]} {
        vwait forever
    }

as mentioned in http://www.sensus.org/tcl/tclsvc.htm

Re: [Tclhttpd-users] Is clock command part of Tcl 7.4

[Brent W. <we...@pa...>]

As a shameless plug, pick up my book,
Practical Programming in Tcl and Tk, http://www.beedub.com/book/
in which I explain what commands were added in what releases of
Tcl and Tk dating back to Tcl 7.4/Tk 4.0 (including what was
new in those releases)
The clock command was indeed added in Tcl 7.5
Also the first time socket appeared, and the first version that
will run TclHttpd.  For general Tcl Q and A, you should also
check out the comp.lang.tcl newsgroup.

[Tclhttpd-users] Is clock command part of Tcl 7.4

[Jempty, G. <JE...@RW...>]

I'm doing this web app on an old Unix box with Tcl 7.4.  The following
straightforward commands don't work:

set today [clock seconds]
puts "$today<br>"

(I tried [clock format [clock seconds]] at first, also without success)

Is "clock" not a valid command in 7.4?  I looked at the online docs, and
there it is for version 7.5, but that's as far back as they go.  With
version 7.4 am I instead forced to resort to:

set today [exec date]

Thanks in advance: this email group has been a big help as I learn Tcl.

    while {[gets $f line] != -1} {

[Tclhttpd-users] Piping uncompress result(s) to open

[Jempty, G. <JE...@RW...>]

This is a general Tcl question but I'm having problems posting to the
general list online.

Can you do something like the following Perl with Tcl?

open(LOG, "uncompress -c '$errorLogPath.Z'|");

Or do I have to uncompress somewhere -- using exec I presume -- read that
(and delete when through)?  I've read the docs but I learn better by
example.

Done it with TclSvc - works great.
Or freewrap it and use ServiceInstaller
Haven't tried firedaemon, but that should work, too.

Re: [Tclhttpd-users] Does tclhttpd run as an NT (actually Windows 2k) service?

[Brent W. <we...@pa...>]

You need to create a special Tcl interpreter to run as a service.
One example is available at
http://www.sensus.org/tcl/tclsvc.htm
and
http://www.sensus.org/tcl/tclsvc11.tar.gz

Has anyone on the mailing list done that yet?
I haven't had time to play with this myself.

[Tclhttpd-users] Does tclhttpd run as an NT (actually Windows 2k) service?

[Jempty, G. <JE...@RW...>]

Greetings!

In my new position I have discovered that one of our third party vendors
allows us to write Tcl scripts to customize an application.  So, to leverage
the Tcl knowledge we thus gain, I intend to do some tclhttpd development, as
I am also responsible for setting up an app server (I've got previous
Apache, CGI, PHP and Unix experience and am confident of catching on
quickly).

To make a long story short, I'm a newbie, but am excited about the prospect
of working with Tcl and tclhttpd, especially considering how incredibly
simple it was to install and then run the web server on my Windows 98
workstation.

I have searched the mailing list archives, as well as the online docs, and
book chapter, but have seen no mention that tclhttpd will run as a service
under Windows NT/2000.  Is that correct?  If so, mind if I submit it as a
feature request on sourceforge?!

Re: [Tclhttpd-users] Extension to read office document properties.

[Brent W. <we...@pa...>]

There is a general Tcl package from Robin Becker called the "DLL Caller"
that basically lets you call any function in a DLL.  You can crash your
program by making bad calls, but once you get it right it is
apparently quite useful.

[Tclhttpd-users] Extension to read office document properties.

[petrus v. <pet...@si...>]

Hi,

We are trying to read out the document properties of win office 97
documents on Windows NT.

This has to be done without starting Excel , Word , etc.
By found out that this is a precondition for the dde package, so we can
not use it.

We know MS provides a ddl called dsofile.dll to do this job in Visual
Basic.

We have investigated possibilities to "transform" VB Code to C and to
create a dll.
Till now we are not successfull.

So the question is, was already someone successfull in reading office
properties
without using dde?
Does there exist a tcl package for this job ?

Thanks,

Re: [Tclhttpd-users] Tcl_EvalFile limitations

[Brent W. <we...@pa...>]

Tcl_EvalFile is equivalent to the "source" command.
The only way to pass parameters is to define global Tcl variables.
argv comes to mind.  You can use Tcl_SetVar to initialize the
variables before calling Tcl_EvalFile.

Another way to do this is to only have procedure definitions in the
file.  Then use Tcl_Eval to invoke a command along with whatever arguments
you want to pass.

[Tclhttpd-users] RE: TclHttpd-users digest, Vol 1 #97 - 1 msg

[Ted D. <tdu...@mu...>]

You can set global variables using Tcl_SetVar and then use Tcl_EvalFile to
source the file into your interpreter.

Of course, if you were on another platform besides Windows, then things
would be waaay easier.

Hi,

Does anybody know how  to execute a tcl file with arguments from a C 
program?. Tcl_EvalFile routine takes only the name of the file as an 
argument. But what if we want to specify arguments along with the file 
name?. So the command line would be

tclsh83 a.tcl a.gif

Tcl_Eval neither interprets source nor tclsh83 as a command

Basically, I am trying to execute a script file from a spwaned off thread.

I am programming on Windows environment.

[Tclhttpd-users] Tcl_EvalFile limitations

[Ashwini K. <ash...@ho...>]

Hi,

Does anybody know how  to execute a tcl file with arguments from a C

argument. But what if we want to specify arguments along with the file 
name?. So the command line would be

tclsh83 a.tcl a.gif

Tcl_Eval neither interprets source nor tclsh83 as a command

Basically, I am trying to execute a script file from a spwaned off thread.

I am programming on Windows environment.

Thanks in advance,
Ashwini

[Tclhttpd-users] Thread package

[Ashwini K. <ash...@ho...>]

Hello,

I am trying to use the thread package extension. I need to spawn  a thread 
from a main thread which does some work. However, I am not able to run it 
asyncronously. Also, I need to be able to kill the worker thread from the 
main thread at any time.

Do you have any examples of using the asyncronous worker threads?. My own 
example follows. Will appreciate if you can tell me if there is something 
wrong that I am doing.

Do I need to subsribe to any other list for answers to these types of 
questions?

Thanks,
Ashwini

##############################################################
load thread.dll thread

proc hello { fi } {

	set pfileID [open $fi w+]
	puts $pfileID "Hello there"
	close $pfileID
	return "Success"
}

#Create the worker thread
set cid [thread::create]

#wait for the thread to start
while {[thread::exists $cid] != 1} {
}

thread::send -async $cid [hello hi.1]
thread::send -async $cid [hello hi.2]

thread::send -async $cid {thread::exit}

###############################################################

In the example above, control comes to the "thread::exit" only after both 
the previous lines have been executed. I have even verified this with a huge 
for loop inside the proc.

Thanx Brent,
Once again, I looked at your book last night, and you cover most of this
there...

Ok, I am already writing the data to a backend.
How, if it is possible, to be able to easily come back to the form, with
its original values, after the redirect? Imagine someone using a
tabnotebook, filling in forms, and bouncing back and forth between
forms? I can even take the risk to write(submit) only once, when the
data entry person is certain...

So, if I understand, the form.tml is built with html::textInput, instead
of <input type=text>.
Any examples of this....

This sounds like it would allow the "tabbing" effect required above,
again any simple example?
This seems that it would also solve the query issue, where you would
like to populate the form with the results of a query?

Anyway, thank-you, for the help, and such a great tool. I am always
amazed at how much functionality is built into tclhttpd

sincerely,

Re: [Tclhttpd-users] Session state in httpd

[Brent W. <we...@pa...>]

I use "self-posting" forms a lot, and I think they will address what
you want.  If you look at the tcllib html:: package you'll see support
to create form elements that have default values for them based on
values in the CGI environment.

So, the basic scenario is that a form always posts to itself.
Then, to get out of that cycle you use a redirect to the next page
in the flow.  So, at the beginning of your page (I'm assuming a .tml
template, but it isn't strictly necessary) you decide if all the form
data is OK.  If it is, then use Doc_Redirect to trigger a redirect
to the next page.  You'll want to save the form data before you do that.
If the data is not OK, then you redisplay the page.  If it is constructed
with the building blocks out of the html:: package, then the previous
values are automatically filled in.

You can also avoid the redirect by passing data from page to page
with a bunch of <input type=hidden> fields.  Or, if you don't like that,
then you can jam values into the CGI environment with the ncgi:: package
so that they are seen by the afore mentioned html:: package routines.

[Tclhttpd-users] Session state in httpd

[Nicolas B. <nic...@ma...>]

Hi all,

Need some advice here on managing session state. I need todo the
following

1. Have user enter data in 5 forms and write them into a db. Domain
handlers made this easy. I am appending to the tables, so I will need
some way to have the system keep table relations...

2. Should a user want to recheck his data, what options are there
outside of always pushing the browser-s "back" button? The forms are
quite complex, so reading the db and generating the forms again is kind
of unrealistic. Sending a list/table of data written is easy, but kind
of defeats the purpose of the forms.

3. Cookies are often referred to; any practical examples of tracking
state using cookies with tclhttpd?

4. Is there any simple way of using the same forms used to input data,
to display the results of a query/edit request? I would think using
Httpd_ReturnFile would work, but how can I populate the form with data;
basically how to push the data back to the user's form?

Anyway, thank you,

Nicolas Boretos

If there is a "tclsh" on vxworks, then tclhttpd may work.

Re: [Tclhttpd-users] base 64

[Brent W. <we...@pa...>]

Right - reading the file in in binary mode is the first trick.
Then you can use the base64::encode procedure that TclHttpd uses
(it is from TclLib)

[Tclhttpd-users] Enhancements/Corrections for Tclhttpd-3.3

[Wolfgang S. K. <wol...@pr...>]

Hi,
here are some corrections and proposals for enhancememnt of the tclhttpd =
V3.3.
I have not had the time to reduce the attachment to a minimum, so I descr=
ibe
the changes. The other ones are mostly config changes specific to our spe=
cial use.

- The tar.gz file lacks the directory config that in turn contains
  the file install-sh, mkinstalldirs, and tcl.m4 (present in release 3.2)=

  Effect: unable to configure/build out of the box.
  Workaround: copied from V3.2
- I needed to rebuild the configure-Skript via autoconf to get the stuff =
working
  (SC_XX macros)
  Workaround: call autoconf in the tclhttpd-3.3 directory
- Please find attached a set of patches that contain the following change=
s:
  + New config item 'exactsearch' that controls the behaviour if pathname=

    completion for images. The existing mechanism does not work for if on=
e
    does not have filename.ext1 (queried by client), but filename.ext2 ex=
ists!
    filename.ext2 is returned, even if the MIME-types for the file-extens=
ions are
    different. (Broken in 3.2 as well)
  + Some MIME-types (ignore)
  + More customization (ignore)
- You should consider to use the error-page 'error.html' directly from th=
e
installation dir.
  Currently, if you configure a new document root, the code assumes a fil=
e
  named 'error.html' underneath the document root. If this file does not =
exist,
  the server hangs and the client browser waits for Godot :-(
  Using the one from the installation as fallback may be wise.
- You should consider splitting the installation in a platform-dependant =
(binaries)
  and platform-depandant part. All Tcl files could make their way into th=
e platform
  independant dir (example: independant-prefix/share/lib), other in prefi=
x/lib
  and prefix/bin. The platform-indepant prefix should equal prefix or can=
 be specified
  as a command line option to configure.
  This last feature would be nice for Tcl/Tk as well ;-)
