Hi Chris,

There isn't any testing framework built into Webmin. However, for some
large modules (Virtualmin and Cloudmin) I have implemented tests by
writing a script that calls the command-line API for the module, and 
verifies the output. However, this requires that your module actually
have a shell API, which can be a lot of work to develop (but is useful
for other purposes).

I'm no expert, but given that this written in Perl, I'd look to that tooling for testing procedures.

Subject: [webmin-devel] module development and testing

Hi,

We're currently looking into writing a webmin module for configuring a proprietary application on our appliance platform (currently targeting Turnkey Linux which includes webmin by default).

I have found the development wiki which has all kinds of useful information, but I can find nothing on testing.

I am interested in how we can unit test (if that is even possible) our module. What are the testing best practices? Is there a test harness we can make use of?

Thanks

[webmin-devel] module development and testing

[Chris C. <cc...@co...>]

Hi,

We're currently looking into writing a webmin module for configuring a
proprietary application on our appliance platform (currently targeting
Turnkey Linux which includes webmin by default).

I have found the development wiki which has all kinds of useful
information, but I can find nothing on testing.

I am interested in how we can unit test (if that is even possible) our
module. What are the testing best practices? Is there a test harness we can
make use of?

Thanks

Oh yes of course. I'm not very familiar with Perl... it works now, thanks!

I think you need to replace the + in those print statements with a . , which is what perl uses to combine strings.

I changed it to:

my $CRFL = "\x0d\x0a";
my $client  = HTTP::Client->new();
my $content = $client->get("http://127.0.0.1:8888/io");

print "Date: " + time2str(localtime) + $CRLF;
print "Content-Type: text/json; Charset=iso-8859-1$CRLF";
print "Content-Length: " + length($content);
print "$CRLF$CRLF$content";

I get the same 500 error. Afaik these are the only required headers for a http response. Do I need to add others to make it work? Is there a log where Webmin tells me what it doesn't like about my headers? (The action log is empty.)

I would look what a normal index.cgi outputs, but I cannot execute it directly from the command line (it says that WEBMIN_CONFIG is not set).

Re: [webmin-devel] ajax with webmin

[PEOPLES, M. P <mp...@at...>]

I'm no expert here, but I would get a protocol analyzer (Wireshark) and/or tcpdump and look at the packet stream that is being sent by an application (browser) that does work with your embedded application.

At least you'll know what a "well-formed" HTTP message looks like so that you can adjust your code accordingly.  You can also look at what is actually being sent by Webmin.  Maybe something is being altered before it is sent.

Finally, you could try transmitting the message with curl or wget ( I can't really tell details, but I know they can do that) to see if it appropriately formatted.

Subject: [webmin-devel] ajax with webmin

Hi everyone,

I am implementing a webmin module for monitoring an embedded system. The webmin installation is primarily used to administrate the OS, but should also be able to show the current status of the main application running on it. I need to use AJAX to automatically update the visualization of some I/O channels.

Now the application has a RESTful, JSON-based interface for accessing its status. The problem is that it does not do any authentication, so it is reachable only from localhost for security reasons. My Webmin module retrieves information from there and renders it. For the AJAX requests, the Webmin module should act like a proxy and just pipe through the content retrieved from the application. I tried the following in a script io.cgi as part of my Webmin module:

my $client  = HTTP::Client->new();
my $content = $client->get("http://127.0.0.1:8888/io");

print "HTTP/1.1 200 OK$CRLF";
print "Content-Type: text/json$CRLF";
print "Content-Length: " + length($content);
print "$CRLF$CRLF$content";

This does not work; when I try to retrieve /myModule/io.cgi, I get:

HTTP/1.0 500 Bad Header
Server: MiniServ/1.620
Date: Tue, 23 Jul 2013 06:07:06 GMT
Content-type: text/html; Charset=iso-8859-1

Is it possible to do this with Webmin?

Hi Felix,

Something like that should work - but you should remove the line
that prints "HTTP/1.1 200 OK". This isn't necessary in any Webmin
CGI script, as the webserver adds that line. The "500 Bad Header" error
happens if your script's output doesn't start with valid HTTP headers.

[webmin-devel] Slow download speeds from webmin

[Mads M. T. <ma...@ma...>]

Hi Webmin developers

I'm having a issue with very slow download speeds from the Upload and
download module.

I've committed a fix to github and created a pull request
https://github.com/webmin/webmin/pull/56.

But should I do anything more to get it into the official version?

Best regards,
Mads

If you do an <input type=number>, most newer browsers will restrict values to numeric, mobile browsers will pop up a numeric keypad, and old browsers will just do a normal text field because they don't recognize that type (and the default is plain text). You can't rely on that (always verify on the server side), and the ui_lib doesn't create these for you, but giving some feedback on the client side this way is almost free, so it's basically win-win. :)

[webmin-devel] Log access

[Emma w. <emm...@gm...>]

Hello,

As part of the module I am writing for tomcat management, I wrote a module
for accessing tomcat logs.

The problem I have is, when I open the page, the default selected fields
should cause the logs to display in the textarea box but this is not so. I
have to click on the "Display" button before the logs get displayed. The
second problem is that, when I select new fields and click on displays, the
logs displays alright but the fields changed back to the default fields
which in normal sense shouldn't be so.

Here is the code below:

 #!/usr/bin/perl

require 'tomcat-lib.pl';
#&ReadParse();
&ui_print_header(undef, $text{'logaccess_title'}, "", "tomcatlog");

#Get all instances
@insts = File::Slurp::read_file( $config{'tomcat_instance'} ) or die
"Failed to read $config{'tomcat_instance'} - $!";


#Log type: access or catalina.out
@log_types = ( "catalina.out", "access_log" );

$in{'inst'} =~ s/\s+//;

$in{'inst'} ||= $insts[0];
&indexof($in{'inst'}, @insts) >= 0 || &error( $text{'no_log'} );

$in{'log_type'} ||= $log_types[0];
&indexof($in{'log_type'}, @log_types) >= 0 || &error( $text{'clog'} );


print &ui_form_start("tomcatlogs.cgi");
print "<b>$text{'inst_select'}</b>\n";
print &ui_select("inst", $in{'inst'},
 [ map { [ $_ ] } @insts ]),"\n";

print "<b>$text{'log_type'}</b>\n";
print &ui_select("log_type", $in{'log_type'},
                [ map { [ $_ ] } @log_types ]),"\n";


$d =`date '+\%d'`;
$m = `date '+\%m'`;
$y = `date '+\%Y'`;

$m, "2") .
                "Year:".  &ui_textbox("ly", $y,"4") .
&date_chooser_button("ld", "lm", "ly" ), "\n";


print &ui_submit($text{'log_display'});

print &ui_form_end();

I cannot speak for Jamie, at whose feet I gladly grovel, but my theory is that it made Webmin and the attendant code more “inclusive” of what might be added to it.   Again, my Perl knowledge is pathetic, but that’s my theory.

What Jamie built, for those of you who have taken the time to really consider it, is a monumental achievement and contribution to system administrators all over the world.  I’m not “polishing apples” here.  I owe countless hours “recovered” through the use of Webmin to the guy.

I'm sure only the webmin developer knows why he did not use strict, however, you can still use it. Just initialize vars you intend on importing thus:

#!/usr/bin/perl

our( %in, %text, %config );

use strict;
use warnings;

etc.....

Older Perl did not support the 'our' pragma, but 'vars.' [1] So keep that in mind if you are using an older Perl.

Yea the same thing I did by removing the strict. When you look at webmin
codes itself, strict is not use anywhere do I guess that is it.

Re: [webmin-devel] Strict

[PEOPLES, M. P <mp...@at...>]

It's not the API that is doing that, it's Perl's interpretation of the code (perhaps that's self-evident).  I have limited Perl knowledge and will defer to others on this.  However, I experienced the same thing when developing my own custom module.  I simply removed the "strict" command and moved on.

Jamie will doubtless be able to explain this better.

Look at the javascript parameter. You should be able to pass in an arrayref

Re: [webmin-devel] Select button

[PEOPLES, M. P <mp...@at...>]

I've been where you're at and gave up on some things.

Your best bet may be to go out and find a JavaScript framework (Dojo, JQuery, etc.) and try to incorporate that functionality into your code.  I'm not entirely sure how the Webmin web server will react to this however.  This won't be easy, but once you've figured out how to make it work within the Webmin environment, you can use other functionality it provides to enhance your modules.  There are lots of neat widgets and components to work with.

Then, you can share what you did with the rest of us and be a hero!

Yea, I did but didn't find anything closer to it. I based on the download and upload module to write the jsp uploading module but only that part I am struggling with.

If you're curious as to which modules might contain such functions, search for JavaScript references in the files.  You can do this finding all the files containing source code, creating a list of them, then looping through the list, searching each file for the "jsp" or other relevant tags.

This may not always work for you, but it's how I created my custom modules.

Hello,

In the module am writing for tomcat, I want to provide two select menu(dropdown menu). There a so many tomcat instance and each of them has applications under them. Now, if someone want to upload a new jsp to a particular tomcat say /var/lib/tomcat5/webapps/myapp is where the jsp will be uploaded to. I want the first select menu to provide the list of all the tomcat instances on the server(This I have done successfully).
The second select menu should contain all the applications under the selected tomcat instance  from the first menu select. so if I select tomcat5, the second select menu should load automatically all the applications under tomcat5.

I know there is a javascript function that can do something like that (onchange or so). But how can I do this? Any help will be appreciated much.

I have my two menu select with the code below:

 print &ui_table_row($text{'inst_select'},
                &ui_select("inst", $in{'inst'},
                    [ map { [ $_ ] } @insts ] ) );

This is not working yet.
print &ui_table_row( $text{'select_app'},
                     &ui_select("ap", $in{'inst'},
                        [ map { [ $_ ] } @apps ] ) );




I will be using the two select menu to construct the directory to which the jsp is to be saved.


Cheers!
