Re: [webmin-devel] adding a "please wait" popup while executing time consuming commands

[marty l. <mal...@gm...>]

I still can't get the behavior I want where I print some text as soon as
possible and then wait.

Here's the relevant parg of a  test .cgi:

$start=qx(date);

ui_print_unbuffered_header('Changing communication mode');
$|=1;
print "started at $start\n<BR>";

my $type_ethernet=$in{'type_ethernet'};

my $type_wifi=$in{'type_wifi'};

set_wifi($type_wifi);
set_ethernet($type_ethernet);

$end=qx(date);

 print "ends at $end\n<BR>";

#print '<meta http-equiv="refresh" content="0;URL=index.cgi">';
footer();

The behavior of the "meta refresh" is what I want (at the end of the
script, go to another page)

But everything seems to print at once:  (with and without the $|=1 trick)

Changing communication mode
started at Wed Jun 4 03:36:49 UTC 2014
ssh stop/waiting ssh start/running, process 20496 ends at Wed Jun 4
03:36:56 UTC 2014

(there should be about a 7 second visual delay between the started and
ends, the data is transmitted instantenously).

I want the data to be transmitted when I write it.

 I've done lots of playing with this simple example wihtout different
results (seems the output is being buffered).

I have webmin being redirected through the SSL of nginx (though I can't
imagine that would be a problem)

Re: [webmin-devel] adding a "please wait" popup while executing time consuming commands

[marty l. <mal...@gm...>]

Thanks -- its ui_print_unbuffered_header.

But after the page is displayed, I want to force a redirect to another page
-- how would I do it

Something like:
&ui_print_unbuffered_header('please wait');
system('date');
print "<BR>\n";
sleep(5);
system('date');
 print "<BR>first line\n<BR>";
sleep(5);
system('date');
print "<BR>second line\n<BR>";

footer();

# redirect('index.cgi');

Sounds like print buffering. Either print enough content to 
flush buffer, or disable the buffer. I don't recall the syntax 
but google will find it for you quickly enough. Something like:

$| = 1;

Re: [webmin-devel] adding a "please wait" popup while executing time consuming commands

[marty l. <mal...@gm...>]

I'm having a problem where my page is delivered on the network at the same
time -- after the delay (I used wireshark to
monitor this)

What I want tried is:

ui_print_header('please wait');
footer();
sleep(5);
print "final\n<BR>";

I would have expected to see the header render, a delay, and "final".

Its all happening after the delay.

What I really want to do is:

display "please wait"
run a long command
redirect to another page (after the command runs)

In some modules, I've had Webmin print out a series of dots (one per second)
while performing some long operation. The code is like :

print "Doing something slow ..";
launch_slow_op_in_background();
while(!done_slow_op()) {
  sleep(1);

[webmin-devel] adding a "please wait" popup while executing time consuming commands

[marty l. <mal...@gm...>]

When having a custom module in webmin execute time consuming commands, how
would I add a
"please wait" message until the command is finished (without user
interaction).

I.e.:

start_please_wait();
system("long_command");
stop_please_wait();

Yes, in your module's config_info.pl file you can define a function
called config_post_save that will be called after the config is saved.

Thanks for all the help...

Is there a way to run a function after the editing has been completed?

(i.e. if we have to "do certain things" before displaying the webmin module
controls)?

Yes, you can control on a per-user per-module basis. In the Webmin Users
module you can click on a user and then on a module name (to bring up
the detailed access control page), and at the top there will be a setting
to determine if the Module Config page is available or not.

Yes - you can create a config_info.pl file in your module, which defines functions
to show and validate a config field define in config.info. See the standard "mysql"
module for an example.

[webmin-devel] questions about module configuration

[marty l. <mal...@gm...>]

1) can "webmin accounts" be involved in the module configuration.
i.e. can "some accounts" which can run the module be selected to "edit" the
configuration.
Can this be on an "option by option" basis?

2) Are there hooks to having a "parser" when free-form text is submitted
(i.e. if you want a "number" between 10 and 100, something which "confirms"
the text field is a number and within bounds (i.e. after a submittal, a way
to run a parser function)

3) Is there a way to hook a function after the module editor is "completed"
so "something knows"
editing has taken place (before the actions on the module are run?)

Any examples which accomplish this (possibly in alternate ways) would be
appreciated.

I'm thinking of having the "editor" as a webmin action so I can control it.

There is basic webserver logging to /var/webmin/miniserv.log , but this doesn't 
have the same detail as what you can get by calling webmin_log.

Yes, that is correct. In an ideal module the CGI script would have very
little actual functionality, and instead would call functions in your .pl
file to do the real work. These could then also be called via XML-RPC.

I wouldn't recommend going this route.

[webmin-devel] question on requirements for webmin modules

[marty l. <mal...@gm...>]

I'm writing custom modules and have the following requirements:
   a) all actions need to log
   b) xml-rpc needs to be able to trigger the actions

It appears  logging is modules written and I've seen it in the .cgi
scripts.  Is there any logging "inherent" in webmin, or is it all module
driven.

It looks like the .cgi scripts aren't accessabile from xml-rpc -- I suppose
to access the "actions" from xml-rpc I'd need to either
      1) put the actions in a method in the library (and invoke it from
both the cgi and the xml-rpc)
     2) have a method in the library to invoke a .cgi script (in which case
the CGI script run without a GUI)

Re: [webmin-devel] ssl with xml-rpc

Make sure that either your Webmin server has a real CA-issued SSL cert, or
that your test script is written to not require a valid SSL cert.

[webmin-devel] Free Disk Space fixed in 1.675

[Eric M. <em...@le...>]

Hi, I just wanted to report that Free Disk Space on right.cgi is definitely fixed for us on 1.675 (using Fedora Core 20).

On version 1.670 it was not reporting the size of the MDADM RAID array, only the one physical disk in the system.

Now it is properly reporting the size of the RAID array + the physical disk.

That would work .. although alternately, perhaps if rfc2307bis mode is enabled
the old-style list of member UIDs could be  replaced entirely by member DNs?

[Stephen G. P. <sg...@ma...>]

Hi Jamie,

The RFC has not changed in four years and I think is unlikely too.
Actually, developing this may not be not as bad as it sounds - e.g. the
attributes are read from LDAP and written to it regardless of the names
I think so backend writing / reading can remain as is.
Here is a break down of what we need:
In module config:
- a checkbox (enable rfc2307bis)
- a text field (dn member attribute name).

In Edit User, Group Membership:
- Secondary Groups - functions just as now, but is relabelled 'Secondary
Groups (by UID)'
- New panel, shown only if rcf2307bis is set  - Secondary Groups (by DN)
- pulls list of groups from the dn member attribute dictated by the
config. The left hand side can be populated in the same way as the
existing panel. The right hand will need a new query of some kind.

In Edit Group, Group Details:
- Members - functions just as now, but labelled 'Member UIDs'
- New panel, shown only if rfc2307bis is set - labelled 'Member DNs'.
The left hand side will need a new LDAP query to populate it. Will need
a new variable to store list in.

In LDAP Groups list:
- Concatenate the two attribute lists together before displaying as
members column

I'll have a look at the code over the holiday and see if I can come up
with a provisional patch.

Stephen

Wow, that sounds like it is going to be painful to support in Webmin.

I may just hold off until the RFC is finalized, to avoid having to 
make changes more than once.

Re: [webmin-devel] LDAP Groups and RFC2307BIS

[Stephen G. P. <sg...@ma...>]

Hi Jamie,

Nss_ldap has a configuration option for supporting rfc2307bis and will
actually pull members from both the uid based and dn based attributes,
even in the same object - see section 5.2 of the draft spec:
http://tools.ietf.org/html/draft-howard-rfc2307bis-02. Hence webmin
would probably have to have an extra field for the DN based attribute
with configuration options to enable / disable each separately. Two
further complications:

1) different implementations use different names for the DN based
attributes (e.g. the DN based attribute is sometimes 'member' (later RFC
versions); other times 'uniqueMember' (early RFC versions), by
comparison the uid attribute is almost always 'memberUid' (as per
original spec))  - hence the name of the DN attribute will need to be
configurable too. The structural classes vary a lot too, thanks to spec
variations, but the existing webmin config allows for that - more or less.

2) An empty group appears not to be allowed in many implementations.

It doesn't help that the RFC is far from complete - 'draft' is correct
because it really is full of holes!

Hi Stephen,

Does using RFC2307bis mean that the schema for Unix users and groups stored
in LDAP changes? My understanding is that the schema is what defines
the names of fields, and that changing this would also break NSS-LDAP (the Linux
library that allows users and groups to be stored in LDAP).

[webmin-devel] LDAP Groups and RFC2307BIS

[Stephen G. P. <sg...@ma...>]

Hi,
I have recently had to reconfigure my OpenLDAP server to use RFC2307bis
groups, rather than the more usual RFC2307. A lot of admins are finding
the need to do this, mainly to get a working memberOf attribute for use
with many popular applications such as owncloud that are too dim to make
separate group and user lookups. The main difference between 2307 and
2307bis is that the members of a group are store in 'member' or
'uniqueMember' attributes, not 'memberUid', and they are DNs not just
uids . Unfortunately, the webmin LDAP users and groups module does not
appear to cope with this. I have stuck my nose into the code and indeed,
the attribute name appears to be hard coded and is uid only. Has anyone
done any work on this? I could try knocking together a patch, but I am
not a perl coder, so the learning curve would be steep.
Thanks in advance

I would definitely use the Perl testing tooling.  I wrote some test

back, and I found it pretty easy & intuitive.  Example here:
