[Mojolicious] Undefined address for Socket::pack_sockaddr_in

[Pavel Serikov]

I got a strange error when make GET request to Mojo server using curl:

Undefined address for Socket::pack_sockaddr_in at 
> /usr/lib/perl5/core_perl/Socket.pm line 851.

Same error I got when running server under morbo and under daemon mode.

What's wrong?

Notice: mojo server is running in docker container.

Mojolicious version : 8.27

Ah, a nice convention!

I’ll add an “add_handle_p()” alias, update the example, and make another 
release.

Ah, nice. Then you can simplify your example too.

my $promiser = Net::Curl::Promiser::Mojo->new();

my $handle = Net::Curl::Easy->new();
$handle->setopt(CURLOPT_URL() => $url);

$promiser->add_handle($handle)->then(
  sub { print "$url completed.$/" },
  sub { warn "$url failed: " . shift },
)->wait;

And if you really want to conform to the Mojo style you rename
add_handle to add_handle_p, because we like to make promise
returning methods obvious. ;)

The latest version does, actually.

Another big disadvantage is that it doesn't use Mojo::Promise. I don't 
think it will attract too many Mojo users without.

Re: [Mojolicious] libcurl via Mojolicious

[Felipe Gasper]

Hi Stefan,

The primary advantage I see is that whatever libcurl features that 
Net::Curl exposes are now readily usable within Mojo. So libcurl’s http/2 
support, for example, should be usable, as would non-HTTP protocols that 
libcurl supports like FTP, IMAP, etc. (Possibly even the experimental http/3 
support?)

Other potential advantages would be speed (XS/C versus pure Perl) and, 
I would think, wider use: as much as Mojo is used in Perl, curl is used 
practically everywhere, with bindings in Python, Ruby, Rust, etc.

The disadvantage is that you’ll need to use Net::Curl::Easy, which 
isn’t a very Perlish interface. HTTP::AnyUA’s backend for same demonstrates how 
to “tame the beast”, though, and Net::Curl’s own documentation is quite helpful 
(IMO), so there’s at least copious prior art to reference.

I should disclaim here: I’ve not benchmarked this nor used it very 
extensively beyond just verifying that it works for simple parallel GETs. That 
said, since Net::Curl::Promiser is fairly simple, and Net::Curl itself has been 
around for a while and remains actively maintained, whatever gremlins may still 
lurk should be easy to find and fix.

Hi, Felipe! Thanks for sharing this! What advantages does integrating with
libcurl have over using Mojo::UserAgent?

[Mojolicious] libcurl via Mojolicious

[Felipe Gasper]

Hi all,

I’ve got a library called Net::Curl::Promiser that does the “dirty-work” of 
interfacing between different event loops and Net::Curl::Multi. I recently 
added a Mojo::IOLoop backend, so it should now be possible to integrate 
libcurl seamlessly into Mojolicious via Net::Curl::Promiser::Mojo.

Hope it’s useful … enjoy!

-FG
