Installing mod_perl for 2 versions of Perl?
Hi, Under Ubuntu 10.04, is it possible to install mod_perl for 2 versions of Perl for the same Apache? I have the default build of Apache that comes with Ubuntu and the default Perl that comes with Ubuntu and I also have the mod_perl installed with apt-get. I want to test ActivePerl 5.14 and I want to install Mod_perl for it but I wouldn't like to need uninstalling the actual Apache/Perl/mod_perl. Thanks. --Octavian

It is technically possible, but you are going to spend so much time trying to combine this properly, that it is probably not worth the effort. You would save yourself a lot of time by using another host, installing your chosen versions of Apache and Perl on it, and then installing mod_perl from source, pointing it to the installed Apache and Perl. Personal opinion, all of it. YMMV.

If you want to compile additional modules make sure they use the right header files and also use the DESTDIR option. By personal experience, I believe that this is over-simplifying a bit. Ubuntu/Debian packages are nice, and they just work. But these packages work by putting (very clever) links all over the place, and I wish good luck to someone wanting to combine this with, for example, another perl and a mod_perl installed from source, while keeping the same Apache. (E.g. if it needs changing the LoadModule line in Apache, then of course you cannot run this concurrently with the normal version.) And trying to install a CPAN package over that, to a directory library that is not the default one, is a real pain. At least the last time I tried. Admittedly, I am not the ultimate perl/mod_perl expert, and in the end I will defer to the real experts. But I believe that the OP is not a real expert either, and for now I'll stick to my earlier recommendation.

PSGI isn't just about portability, it's also about middleware. With a common interface between components we get out of the rut where each new cool plugin was re-implemented by every existing framework. Now most things can just be written as PSGI middleware and anything can use it no matter what your framework (or lack of one). For instance, these are some handy ones to have: Plack::Middleware::InteractiveDebugger Plack::Middleware::REPL Plack::Middleware::Firebug::Lite Plack::Middleware::JSONP Plack::Middleware::RefererCheck Plack::Middleware::Static::Minifier Plack::Middleware::HTMLMinify Plack::Middleware::Mirror Plack::Middleware::iPhone And there's a ton more. Yes lots of them can be done with other existing Apache modules (but not all of them) and lots of them might already exist in your framework of choice. But pulling things out into middleware seems to be the future of such work and will thus get new features and be better maintained than lots of other alternatives. -- Michael Peters Plus Three, LP

Re: mod_perl EC2 AMI's or other platform providers?
I saw Miyagawa at YAPC::NA and it looks like DotCloud is serious about their Perl support. The situation seems pretty good to me. We have DotCloud, for people who want to try something simple very quickly with minimal startup costs. We have cheap virtual servers (e.g. Linode) running linux with simple installation of pre-compiled perl, apache, and mod_perl, for those who want a little more control but can live with outdated versions in exchange for ease of administration. Then we have compile-your-own, for those running large systems who want the latest versions and need the best performance and debugging possible. I don't think we're missing anyone at this point. - Perrin On Sun, Jul 10, 2011 at 7:22 AM, Dave Hodgkinson daveh...@gmail.com wrote: Also, I believe DotCloud has Miyagawa on board which is a big win IMHO.

Changing browser URL based on condition
Hi All,
I would like to know if there is a way to change the URL displayed on
browser without using Redirect option. The URL visible on client browser
must be based on some condition that is evaluated in my mod_perl handler.
For example -
1. User types the URL - www.example.com, this will display the login page.
2. Once the user enters the credentials and hits submit, the request is
posted to www.example.com/login action.
3. If the credentials entered by the user is valid then i would like to show
the home page..uri
4. I am able to show the homw page, but the URL does not change to
www.example.com/home, instead it remains the same (i.e.
www.example.com/login). I am using Template toolkit to render my pages. I
tried $req-url('/home'), but that does not change the browser URI.
Any help will be appreciated.
Thanks,
Jerry

Re: Changing browser URL based on condition
From: Jerry Pereira online.je...@gmail.com Hi All, I would like to know if there is a way to change the URL displayed on browser without using Redirect option. Nope, not possible. You need to do that redirection somehow. What the user sees in the address bar is the URL accessed by the browser. If the browser is not told to access a certain URL, how can that URL appear in the address bar? Why don't you want to do that redirection? It is pretty common (and recommended) to do a redirect after POST because in that case the users won't need to meet that ugly warning window that appear if the user does a page refresh after the POST. Octavian
Re: Changing browser URL based on condition
Hi Edward,
I have the following design:
A single PerlResponseHandler for all requests. This handler based on the
path decides the action to be taken
For example, if the user submits to www.example.com/login, then the handler
delegates the request to authentication module, which will then either
display the home page (throug home page template) or login page again, based
on the success/failure of authentication mechanism. Since i am rendering the
page via template, i am able to generate the content of home page which i
then send back to the client, but the URL on the browser remails the same
(i.e. www.example.com/login), which is not true. Any suggestions to handle
this scenario will be great.

They say that for the moment they don't really support Windows but I read a blog with some tips for making it work under Windows. The problem was that rsync didn't work under Windows, or at least this is what their client program said. I have installed cwRsync that includes cygwin and rsync, but I don't know for what reason... it didn't work. For the moment their pricing plan is not clear for me. 0 USD/Mo is clear, and I understand that for this it offers 2 services, that can be say... Perl and MySQL. The second level... is 99 USD/Mo for which they offer 4 services, but without beeing clear about the processors/memory/space (or I missed that part), and this second step is much expensive than the first few tariff plans of linode. I was interested by DotCloud because I wanted to see how accessible is the interface they offer, but for the moment... it is not very. If you know something more about these, please tell us. Perl programs are usually harder to deploy than the PHP apps, and it would be very good if there would be a solution easy to use for apps wich are a little more complex. Octavian
Re: Changing browser URL based on condition
Much better to go with a more RESTful approach - the URL is the identifier
for the page and you don't want that identifier to represent the wrong page,
e.g. if example.com/login sometimes returns the home page and sometimes
returns some other page (assuming you can login from and return to multiple
pages.)
Make it so that your home page (or any page) have a login form (or link
which expands to a login form) which POSTs to the login page (or to think of
it in a RESTful way, PUT to a sessions URL, thus defining the idea of
create a new session - except that browser forms have problems with PUT).
Then from the login page do a redirect to whatever was the referer.

One important reason to do something like that is because you do not want the user to bookmark or otherwise pass on an url with completely ambiguous content -- /login should refer to the login page, /home should refer to the home page, they are two different things. Having /login refer to both is no good. So I think your desire is justified. IMO, this is best handled client-side: you return your login data via an AJAX call. If the login succeeds, the client loads /home. If the login has failed, the client displays a message to that effect. You need to prevent spoofed access to /home, but of course you have to do that anyway (via cookies or whatever method you are already using). -- Enthusiasm is not the enemy of the intellect.

Re: Changing browser URL based on condition
Agree with the consensus. The URI should be descriptive of the
function, so any requests to /login should be from users who are
attempting to... login. The home page should be housed under a separate
URL (/home for example)
After the user has authenticated, the login module should redirect to
the /home URI. Any links to the home page from within the application
should likewise refer to /home. You should have security in place to
redirect any unauthenticated users to /login before requests for /home
(or any other part of your application) are processed.
If you for some reason simply MUST keep referring people to /login when
they are expecting to see the home page, put code in your login module
to check for authenticated users and redirect them to /home before
displaying the login page. If the user doesn't have a session, then go
ahead and display the login form.

RE: Changing browser URL based on condition
I think you need to do a redirect. From within your mod_perl handler try
something like this:
$r-content_type(text/plain);
$r-headers_out-set(Location=$url);

Subject: Changing browser URL based on condition
Hi All,
I would like to know if there is a way to change the URL displayed on
browser without using Redirect option. The URL visible on client browser
must be based on some condition that is evaluated in my mod_perl handler.
For example -
1. User types the URL - www.example.comhttp://www.example.com/, this will
display the login page.
2. Once the user enters the credentials and hits submit, the request is
posted to www.example.com/loginhttp://www.example.com/login action.
3. If the credentials entered by the user is valid then i would like to show
the home page..uri
4. I am able to show the homw page, but the URL does not change to
www.example.com/homehttp://www.example.com/home, instead it remains the same
(i.e.
www.example.com/loginhttp://www.example.com/login). I am using Template
toolkit to render my pages. I
tried $req-url('/home'), but that does not change the browser URI.
Any help will be appreciated.
Thanks,
Jerry

Re: Best approach to store Application Configuration
Hi Jerry.
I went through a couple of different approaches before settling on using YAML
files to describe configuration.
There are several nice properties of YAML IMO, not least of which is arbitrary
nesting so the config can closely match the software being configured.
Here is a sanitized example of my production config:
# -*- mode: perl -*-
# configuration file for XXX
config: { version: 1 }
# XYZ configuration
# across the entire XXX tier
xyz: {
# enable / disable all ...
feature_X_enabled: true,
# name of cookie(s) to emit: [xx, yy, zz]
emit_cookies: [ xx ]
# substructure configuration
sub_structures: {
disabled: {
foo: [],
bar: [],
baz: [],
}
}
}
There are several YAML readers available; I preferred YAML::XS because of its
speed and correctness.
My apps need to run a long time, so they poll the configuration file every n
seconds, and reload it if needed.
Overall, I was pretty happy with this approach, and so were the operations
folks who have to configure the settings in production.

Re: Best approach to store Application Configuration
Naming the path to the config file in an httpd conf will certainly work. In my case, the path the config file is hard coded in the method that reads the config as it is not something that changes. Here is on of my httpd conf file (a separate file loaded in the http configuration directory so your install process doesn't have to change the actual httpd.conf): PerlModuleYour::App PerlPostConfigHandler Your::App::httpd_start Location /foo/app SetHandler modperl PerlResponseHandler +Your::App # Apache::DBI needs GlobalRequest PerlOptions +GlobalRequest /Location The httpd_start method gets called at apache startup time, and reads the config in once. Also, one other possible advantage to YAML is that YAML is not perl, so if you have a mixed language env, it is easy to share/move/port your config to the language of your choice. YAML has pretty good support across the common languages you will find in the LAMP world. BTW, if you haven't already done so, I recommend becoming familiar with the handlers and their life cycles: http://perl.apache.org/docs/2.0/user/handlers/server.html http://perl.apache.org/docs/2.0/user/handlers/http.html#HTTP_Request_Cycle_Phases Have fun, -- jeff From: Jerry Pereira online.je...@gmail.commailto:online.je...@gmail.com Date: Mon, 11 Jul 2011 16:41:13 -0500 To: Jeff McCarrell jmcca...@akamai.commailto:jmcca...@akamai.com Cc: modperl@perl.apache.orgmailto:modperl@perl.apache.org modperl@perl.apache.orgmailto:modperl@perl.apache.org Subject: Re: Best approach to store Application Configuration please correct me if I am wrong, I should be using tool like YAML/Config::General for application configuration storage and reteieval, and load them on startup using startup.plhttp://startup.pl script?

Again, if you think about just using a mod_perl specific way of doing this you'll leave all of your non-mod_perl stuff out in the cold and any project of significant size is going to have some non-mod_perl processes involved somewhere. I prefer to use environment variables if you need to specify the location of a config file.

Almost certain that Apache2::Reload was not the root cause, but it was certainly heavily implicated in the problem and resultant instability. If anyone's interested in a crash dump I can re-enable this module temporarily and try and generate one for you. I experienced similar problems many years ago with Apache2::Reload in a Microsoft Windows environment. Although disabling Apache2::Reload did reduce the problem, it didn't completely eliminate it and instability continued, although much less frequently and after much longer time periods. After having additional troubles with .DLL files and the perl.exe.manifest file, I finally abandoned Windows and now run everything under NetBSD Unix which simply doesn't exhibit these problems for me... I know this probably isn't the most constructive solution for you, but it's good to know that there are other options. I suspect that there was some problem either with Apache HTTPd or one of its modules (and I haven't ruled out ModPerl 2 or APR 2), or MS-Windows itself. The main reason I gave up on Windows is that each OS version exhibited different patterns of when and how the crashing occurred. On one system I saw blue screens, on another the system would just stop responding (and there were less than 10 simultaneous connections at any one time due to limits on the external firewall, so this wasn't it either), and then on another I had problems with Apache HTTPd just crashing with a variety of different error codes in the Windows Event Viewer thingy. I could not narrow down specific results to a particular version of Windows, but Unix did solve the problem for me while also yielding better performance so I decided to just ignore this problem and [mostly] forget about it.
