user agent & capture groups

[rasta]

Hi Guys!

Using Mojolicious 7.93 I face a rather mysterious issue:

In my app I call 

my $upload = $c->req->upload('file');
my $ua = Mojo::UserAgent->new;
my $post = $ua->post($url => \%headers => form => { file => { file => $upload->asset }} );

where $upload->asset is a Mojo::Asset::Memory in my case.

So far so good, Mojolicious makes the post and sends headers a la

   Mojolicious (Perl)
    multipart/mixed; boundary=S3ylX
    Accept-Encoding: gzip
    1201

(captured through tcpdump)

At some point, I added a check on some data before posting, using a match

if( $data =~ m/(\w+)\/(\w+)/)...

Suddenly, what came out of Mojolicious was

    Mojolicious (Perl)
    n; boundary=jthCXf
    Accept-Encoding: gzip
    1201

Not only 'multipart/mixed' is replaced with 'n', the boundary is actually wrong too.

In the end I found out it happens because of the capture groups in the match. If I don't use them

if( $data =~ m/\w+\/\w+/)...

all is fine again.

Is it possible that Mojolicious uses $1 etc somewhere inside the UserAgent to manipulate headers without calling a match first?

Cheers,

Rasta
