Hi, I have a problem when trying to run a PAR (1.002, ~::Packer 1.009) compiled executable which uses POE 1.311 and POE::Component::Client::HTTP 0.943, which uses POE::Coponent::Client::Keepalive 0.267, which finally uses POE::Component::Resolver 0.912.
In short. the problem occurs when Resolver.pm tries to instantiate wheels with
Program => (
($^O eq "MSWin32")
? \&POE::Component::Resolver::Sidecar::main
: [
$^X,
(map { "-I$_" } @INC),
'-MPOE::Component::Resolver::Sidecar',
'-e',
'POE::Component::Resolver::Sidecar->main()'
]
),
In other words, to keep the executable footprint low (lower than just a fork),
the code tries to run $^X (which is set to "perl" ...),
but then of course ends up with an arbitrary variety of failures.
IMHO it should be possible to use the Windows "solution" also in the PAR case,
but given a decent large executable
the question is whether there would be any chance for the "cheap sidecar"
solution Rocco has intented.
If possible, a solution should avoid the PAR unpack overhead (that is, start
directly from within $ENV{PAR_TEMP}
and execute the code (a la pp --reusable), but we might also have a (security)
clash with option -e ...
Another but smaller problem is that I have not seen an easy way to tell
POE::Component::Resolver all the way down
from POE::Compoent::Client::HTTP that I would like to see less than 8
subprocesses for the resolver job.
Any hints appreciated.
Best regards,
Markus
