Hot code upgrades do not start porcelain #41
Description
I am using https://github.com/gutschilla/elixir-pdf-generator which depends on porcelain.
Elixir: 1.4
Erlang: 19
Porcelain: 2.0.3
Everything works fine, but when I do a hot code upgrade using releases with distillery, I can get error when call the pdf/porcelain code after the upgrade:
Ranch listener MyApp.Endpoint.HTTP had connection process started with :cowboy_protocol:start_link/4 at #PID<0.24063.0> exit with reason:
{{%Porcelain.UsageError{message: "Looks like the :porcelain app is not running. Make sure you've added :porcelain to the list of applications in your mix.exs."},
[{Porcelain, :driver, 0, [file: 'lib/porcelain.ex', line: 419]},
{Porcelain, :"-exec/3-fun-0-", 3, [file: 'lib/porcelain.ex', line: 131]},
{Porcelain, :catch_throws, 1, [file: 'lib/porcelain.ex', line: 273]},
{PdfGenerator, :generate, 2, [file: 'lib/pdf_generator.ex', line: 136]},
{PdfGenerator, :generate_binary, 2, [file: 'lib/pdf_generator.ex', line: 188]},
...
]},
{MyApp.Endpoint, :call, [
%Plug.Conn{ ... }}When I restart my application/release it works again. So this currently prevents me from using hot code upgrades. Everything else works after the upgrade.
Porcelain is added in the mix.exs file:
def application do
[mod: {MyApp, []},
extra_applications: [
:logger,
:runtime_tools,
:misc_random,
:porcelain
]
]
endI also tried to add it to the distillery release config, without a difference.
Any ideas? Is it better to post this on pdf_generator or distillery issue tracker?
