[Mojolicious] Using 'state' in a helper

[Viktor Nacht]

Does using state inside a helper last for the duration of the connection, 
or something longer lasting like a process, worker, etc?

I want to create (and return) a current DateTime object and make it 
accessible to multiple helpers and templates during a connection.

I saw this Gist, but I'm not sure it pertains to per-connection:

Re: [Mojolicious] Using 'state' in a helper

[Dan Book]

A 'state' variable lasts for the rest of that process, but is only
available to the scope it's declared in. If you want per-connection (or
more precisely per request), I recommend storing it in the stash, like:

helper foo => sub {
  my $c = shift;
  return $c->stash->{'myapp.foo'} //= ...;
};

Dear Mr Henq,

Please see a fresh new thread on this mailing list, that I'll be posting
in a few minutes, with a subject line of "Apache Config for Mojo CGI
setup - opinions?".

[Mojolicious] Apache Config for Mojo CGI setup - opinions?

[Alexander Karelas]

I have made some webapps that I use internally. I use them so rarely
(just a couple of page views per week each) that I thought it wasn't
worth having a hypnotoad running for each and waste resources (RAM
mainly), especially since the number of these webapps might increase a
lot in the future, and I don't care about response time (2 seconds is
fine) so I thought I'd set them up as CGI sites.

With some experimentation, I ended up with this Apache conf file the
VirtualServer (for Apache v2.4). It routes arbitrary URLs to the right
route handler.

What do you think of it? Is it secure (suppose an evil user has access
to it)? Can it be improved? Can it be simplified, maybe? Is this useful
material for the mojo Wiki / POD?

I'm interested in your opinions, because my experience with Apache is
not that big.

[Mojolicious] Re: Apache Config for Mojo CGI setup - opinions?

[Alexander Karelas]

I should note that the entire webapp (the templates/ subdir, the public/
subdir, etc) resides in the cgi-bin/ directory. my_app.pl happens to be
a Mojolicious::Lite app in this case.

Re: [Mojolicious] Apache Config for Mojo CGI setup - opinions?

[Dan Book]

Even simpler, I think, is to alias everything to your one script, so you
don't have to worry about what else might be in that directory.

ScriptAlias "/cgi-bin/" "/opt/mysite/cgi-bin/my_app.pl"

https://httpd.apache.org/docs/2.4/mod/mod_alias.html#scriptalias talks
about some strategies for this.

[Mojolicious] Re: Apache Config for Mojo CGI setup - opinions?

[Alexander Karelas]

Something strange:

On a fresh CentOS 7, this conf works (i.e. mapping to
/cgi-bin/my_app.pl/further/path actually executes /cgi-bin/my_app.pl)

But on a fresh Ubuntu 18.04, it doesn't (I get a 404 Not Found because
script /cgi-bin/my_app.pl/further/path does not exist).

Don't know how to fix this on Ubuntu.

[Mojolicious] Improved version / Was: [Re: Apache Config for Mojo CGI setup - opinions?]

[Alexander Karelas]

Thanks to Dan Book, I searched a bit more. Plain ScriptAlias didn't do
the trick, but ScriptAliasMatch worked beautifully on both CentOS and
Ubuntu (provided you enable the cgi module of Apache, of course, which I
hadn't done before, and mysteriously wasn't getting an error for unknown
Apache directives):

This apache config seems a lot simpler and more secure, I think,
therefore better.


***
**  ServerName apache-dev.lxd**
**  DocumentRoot /opt/mysite/html*

*  ScriptAliasMatch "^/cgi-bin/(.*)" "/opt/mysite/cgi-bin/my_app.pl/$1"**
