Absolutely true to my surprise. That means you can't return proper
content-type and content-encoding with non-OK codes, Apache will
rewrite it for you anyway, which is too human-oriented and imho
should be corrected. I ended up generating usual successful response
with custom status (which is 500 in my case):
$r->status($self->response->code);
$self->response->headers->scan(sub { $r->header_out(@_) });
$r->send_http_header(join '; ', $self->response->content_type);
$r->print($self->response->content);
&Apache::Constants::OK;
Probably worth mentioning in FAQ or somewhere. It took quite a bit of
my time.
Best wishes, Paul.

Thanks for the help, but it seems like I'm using it already:
$self->response->headers->scan(sub { $r->err_header_out(@_) });
# ---^^
$r->content_type(join '; ', $self->response->content_type);
$r->custom_response($self->response->code,
$self->response->content);
it's the same as to use err_headers_out as far as I understand. What
is the general procedure to generate custom content-type along with
SERVER_ERROR?
sub handler {
...
$r->content_type('text/xml; charset=utf-8');
$r->custom_response($self->response->code,
$self->response->content);
$self->response->code;
}
doesn't work if '$self->response->code' is 500. mod_perl overrides my
content-type with text/html.
Best wishes, Paul.

[Problem] Can't return Content-type with SERVER_ERROR
Hi, All!
Code is simple, but I can't return custom content-type with
SERVER_ERROR:
sub handler {
. $self->response is HTTP::Response object
if ($self->response->is_success) {
$self->response->headers->scan(sub { $r->header_out(@_) });
$r->send_http_header(join '; ', $self->response->content_type);
$r->print($self->response->content);
} else {
$self->response->headers->scan(sub { $r->err_header_out(@_) });
$r->content_type(join '; ', $self->response->content_type);
$r->custom_response($self->response->code,
$self->response->content);
}
$self->response->code;
}
In ALL cases (200OK and 500ServerError) I need to return error code,
content, content-type and optional headers.
Regardless of my settings content-type is always "text/html;
charset=iso-8859-1" which I expect to be "text/xml; charset=utf-8":
HTTP/1.1 500 Internal Server Error

Let me know what do you think and we definitely should talk in

would be glad also to work on SOAP-enabling taglib library and on
better COM integration. Thanks, Matt!

Agree. It can be built as simple SOAP call against your server.
Though I'm finding many similarities between publish/subscribe and
async messaging they share common problem in this aspect: client has
to tell server where to run callback or response in async model. You
don't need it if you have static environment (when you're responsible
for client and server and client has fixed endpoint), but that's not
interesting case for us.
What can be done in my understanding (and I'm working on it), we can
pass either URL for service description that is able to handle
callback, or even fragment that describes it.
--
Notification service.
Author creates the resource (something that can be pointed by URL and
may be interesting for others) and registers it:
manageResource(URL, {name, description})
System responds with status of the request: registered or not.
Registration may fail if URL is already registered or system decided
you may not register such URL (its not on your IP address) or for
any other reason.
User would like to know about any changes for specified resource. She
sends request and asks register her for this resource and send
notification if something changes:
manageNotification(URL, {notification} [, granularity])
Notification specifies how user would like to be notified (HTTP,
SMTP, etc), in which format and granularity specifies for which event
(resource updated, dropped, etc.). Notification registration may
succeed or fail for reasons similar to resource registration.
Author modifies the resource and would like to notify everybody who
is registered about update:
manageUpdate(URL, message)
It will register update with specified message for particular
resource and notify everybody who is subscribed for this resource.
User can be notified in two modes: active and passive. Active mode
supposes you have something that is able to accept notification, like
http server (for HTTP or SOAP requests) or mail account (for SMTP
requests), and passive notification will be stored on server and you
can come later and read notifications youve got (source, message and
time). You can combine these approaches: subscribe in active mode for
something youre urgent to know about and in passive mode for
everything else.
--
Notification is simpler because server knows exactly what parameters
he wants to pass. For example, I'd like to manage Meerkats checks
against my web site (for some sites one hour can be too often and for
others it can be to rare) and to achive that, I need to register URL
of my site with notification server (as author), Meerkat needs to
register (as User of this resource) and then I just need to send
updates to notification server and it will take care about the rest
and will notify eveybody who is subscribed for this service. Almost
nothing has to be changed on Meerkat's side, and other users can
register for the same service, like search engines, catalogs or
anybody else (like you and me).
Asynchronous messages are little bit different (actually it's not
neccessarily should be SMTP against POP3, it could be HTTP only, but
process on server side could take significant amount of time): A
calls B, then B calls A. Two problems: A should let B know how to
call it and pass something that will let Alater identify that this is
response for particular request, like messageID.
This model can definitely be built on top of SOAP (I hope to have
demonstration soon), but it'll require design changes in toolkit on
client side. I'd like to stay with 'collection' interface, when:
A collectionserver
--request-->
add MID --request-->
accept request with MID and
collection's endpoints
start process and
make fake response
<-response--
<-response-- with MID
time passed.
client runs request for particular MID
--request-->
nothing for you yet
<-response--
finish process and
make real response
<-response-- with MID
--request-->
yes, we have something for your MID

Re: [ANNOUNCE] Apache::SOAP 0.47 (mod_soap)
Hi, Gunther!
> Is there any way to add an interface to basically provide
> serialization and
> deserialization hints? My experience in the way we use SOAP is that
There is no way to ptovide hints, but you have several options to
alter serializer/deserializer and use all other infrastructure. For
example, you may override serializer completely from scratch and then
register it with:
my $soap = SOAP::Lite->serializer(My::Serializer->new)->...
Or you may inherit your own serializer and specify it in the same
way. The same thing is true about deserializer and about server side
(these methods are available there also).
I did some tests with overriding serializers and truly results are
surprised me at least a little bit. Script is below. Results:
o - (1)x200: 23 wallclock secs (23.68 usr + 0.00 sys = 23.68 CPU) @
4.22/s (n=100)
o - (1x100)x200: 25 wallclock secs (24.99 usr + 0.00 sys = 24.99
CPU) @ 4.00/s (n=100)
a - (1)x200: 15 wallclock secs (15.33 usr + 0.00 sys = 15.33 CPU) @
6.52/s (n=100)
a - (1x100)x200: 16 wallclock secs (16.14 usr + 0.00 sys = 16.14
CPU) @ 6.20/s (n=100)
t - (1)x200: 6 wallclock secs ( 5.11 usr + 0.00 sys = 5.11 CPU) @
19.57/s (n=100)
t - (1x100)x200: 6 wallclock secs ( 6.15 usr + 0.00 sys = 6.15
CPU) @ 16.26/s (n=100)
x - (1)x200: 2 wallclock secs ( 2.08 usr + 0.00 sys = 2.08 CPU) @
48.08/s (n=100)
x - (1x100)x200: 3 wallclock secs ( 3.19 usr + 0.00 sys = 3.19
CPU) @ 31.35/s (n=100)
First is default serializer.
Second makes serialization only for first element of array and then
duplicates the results, emulating procedure for one type for all
elements. 50% better
Third generates ready to use xml and provides it as the result (you
may provide xml fragments during serialization) using serializer's
tag function. Almost 5 times better comparing to default.
Forth generates xml with by-hand coding. Almost 10 times better than
default. Everithing else is generated by serializer, so you can
insert your fragment seamlessly.
It's definitely something to think about. I'll take a closer look,
but it shows that having some information about data structure you
may significantly speed up this process. You may alter serialization
depending on user-defined class, depending on Object class, depending
on ref type (array, hash, scalar), etc., so you have almost full
control on serializer behavior. Create you own, override what you
need, register it and you're done.
Here is the script
# -- -- -- -- -- -- -- -- -- -- --

Hi, Adi!

I see I wasn't the only person who starts with adding Array support
to it and I even made my copy of it SOAP1.1 compliant, but then Keith
came with his compliant version.
As for performance, I tried and got similar results on my machine. I
don't know your environment, so I included all my scripts, so you may
try them on your machine and let us know.
Anyway, here is my results (win98):
Benchmark: timing 10 iterations of 100x100, 1x100...
100x100: 10 wallclock secs ( 9.72 usr + 0.00 sys = 9.72 CPU) @
1.03/s (n=10)
1x100: 9 wallclock secs ( 9.17 usr + 0.00 sys = 9.17 CPU) @
1.09/s (n=10)
So, time is about 1 sec for roundtrip to mod_perl (serialization -
deserialization - invocation - serialization - deserialization)
Time for serialization only is different:
Benchmark: timing 100 iterations of (1)x200, (1x100)x200...
(1)x200: 23 wallclock secs (23.34 usr + 0.00 sys = 23.34 CPU) @
4.28/s (n=100)
(1x100)x200: 25 wallclock secs (24.99 usr + 0.00 sys = 24.99 CPU) @
4.00/s (n=100)
So, about 4 times bette. Same script on Linux (serialization only):
Benchmark: timing 100 iterations of (1)x200, (1x100)x200...
(1)x200: 5 wallclock secs ( 5.53 usr + 0.01 sys = 5.54 CPU)
(1x100)x200: 6 wallclock secs ( 5.79 usr + 0.02 sys = 5.81 CPU)
About 18 times a second.

That's right, but first Perl caches calls that involve inheritance
and second, I use the same scheme, because arrays can have everything
inside and I need to call serialization function for every element in
array. I did profiling for several versions and did some
improvements, but there is no obvious stopper.

I'd like to know your results, with your Array implementation. Thank
you.

First thing I did seven months ago was my email to Keith Brown (author of DM's SOAP/Perl module) about possible ways for cooperation and I'v been told that he's willing to, but design of his module should be consistent with other DM's implementations and he has no plans to change it. There was no easy way to combine our efforts and I came up with another implementation. Don't want to praise myself, but feature set seems to be pretty comparable with other toolkits. I took ::Lite, just because SOAP namespace was already taken. It does much more than you can expect from something with suffix Lite. "Lite suffix reflects number of calories you should spend using this module". > In that case, maybe you should call it Apache::SOAP::Lite rather > than Apache::SOAP I thought about it, and in fact I released UDDI::Lite, but I also plan to release DBD::SOAP, DBIx::SOAP and couple of other modules and don't want to put suffix Lite everywhere, it could lead to confusion. Also I don't think (IMHO) that DevelopMentor will ever support their module, since they abandon SOAP development in Java, C++ and Perl and there is no other SOAP modules in Perl and I don't have plans to stop development any time soon. Moreover, I have a long TODO list :). > find out about your SOAP::Lite module and vice versa.

Right, but there is no module specific code (it basically parameters parsing), so I think I'll keep it inside SOAP::Lite for one more version and then release as mod_soap. > Another positive thing about keeping the bundle under SOAP::Lite is > that > you might consider releasing SOAP::Lite server code for other > persistent > engines like PerlEx, Velocigen, SpeedyCGI, etc... and you could It works actually with Velocigen and as far as I understand with PerlEx also, but I don't have any information about SpeedyCGI. It also provides Daemon, TCP, CGI, IO, POP3 interfaces on server side (in addition to mod_perl and Apache::Registry) as well as COM interface and (hm, did I say already that I don't want to praise myself?) > And hopefully these comments will help you decide for yourself what > you'd like to do.

[ANNOUNCE] Apache::SOAP 0.47 (mod_soap)
Apache::SOAP provides SOAP server functionality by simply adding
couple of line in .htaccess or .conf file. Based on SOAP::Lite
module, hence inherits all functionality, like, for example,
compression on wire introduced in last version. For now released as
part of SOAP::Lite module.
Is there any value to ship it separately (probably as a mod_soap)?
Module is available from www.soaplite.com or CPAN.
Documentation and examples are included. Any comments are very
welcome.
Best wishes, Paul.

=head1 DESCRIPTION
This Apache Perl module provides the ability to add support for SOAP
(Simple
Object Access Protocol) protocol with easy configuration (either
in .conf or
in .htaccess file). This functionality should give you lightweight
option
for hosting SOAP services and greatly simplify configuration aspects.
This
module inherites functionality from SOAP::Transport::HTTP::Apache
component
of SOAP::Lite module.
=head1 CONFIGURATION
The module can be placed in , , ,
directives in main server configuration areas or directly
in .htaccess file.
All parameters should be quoted and can be separated with commas or
spaces
for lists ("a, b, c") and with 'wide arrows' and commas for hash
parameters
("key1 => value1, key2 => value2").
All options that you can find in SOAP::Transport::HTTP::Apache
component
are available for configuration. Here is the description of most
important
ones.
=over 4
=item dispatch_to (LIST)
Specifies path to directory that contains Perl modules you'd like to
give
access to, or just list of modules (for preloaded modules).
PerlSetVar dispatch_to "/Your/Path/To/Deployed/Modules,
Module::Name, Module::method"
=item options (HASH)
Specifies list of options for your module, for example threshold for
compression. Future versions will support more options. See
SOAP::Transport::HTTP documentation for other options.
PerlSetVar options "compress_threshold => 1"
