如果不调用机架/葡萄 api 端点，OCRA 会丢失库的子模块 [英] OCRA missing submodules of libraries if rack/grape api endpoints aren't called

问题描述

我正在尝试使用 OCRA 将我的 REST 应用程序打包到可执行文件中.我的脚本中需要一些宝石:

I'm trying to pack my REST app into into an executable with OCRA. I have a few gems required in my script:

require 'rack'
require 'rack/server'
require 'grape'
require 'grape-entity'
require 'rubygems'

我跳过用这个启动服务器:

I skip starting the server with this:

if not defined?(Ocra)
    Rack::Server.start options
end

当我尝试运行我的 server.exe 时:

When I try to run my server.exe:

Temp/../server.rb:221:in `default_middleware_by_environment': 
cannot load such file -- rack/content_length (LoadError)

这意味着它不检测存在但未使用因此不包括在内的机架子模块.如果我添加一个 require 'rack/content_length' 它会继续 cannot load such file -- rack/chunkedEven` 等等.

Which means that it doesn't detect submodules of rack that exist, but aren't used and therefore not included. If I add a require 'rack/content_length' it continues with cannot load such file -- rack/chunkedEven` and so on.

当我手动中断服务器时，我还不得不调用一些 api 端点以包含所有内容.

When I interrupted my server by hand before I also had to call a few api endpoints to have everything included.

我认为我的选择是:

• 告诉 OCRA 包含rack 和grave 的所有子模块，但编译该列表有点耗时，并且会增加文件大小

• Tell OCRA to include all the submodules of rack and grape, but compiling that list is a bit time consuming and would increase the file size

我已经尝试过 ocra server.rb --gem-full=rack --gem-full=grape，它可以启动我的服务器，但是在调用 API 'rack/mount/strexp' 时又不见了..

I already tried ocra server.rb --gem-full=rack --gem-full=grape, which get my server started, but when calling the API 'rack/mount/strexp' is missing again..

在我的脚本中调用 API，但我不知道该怎么做.我无法向 Rack::Server.start options 添加块，它只会在我中断服务器时继续.

Calling the API within my script, but I couldn't figure out how to do that. I can't add a block to Rack::Server.start options and it does only continue when I interrupt the server.

有什么想法可以实现任一选项，还是有其他解决方案?

Any ideas to implement either option, or is there another solution?

推荐答案

如果我们使用机架处理程序(webrick/Thin/else)运行机架应用程序，我们可以在另一个线程中关闭服务器，以便 ocra 可以完成打包(不知道如何用 Rack::Server 做同样的事情.

If we run the rack app with a rack handler (webrick / thin / else), we can shutdown the server in another thread so that ocra can finish packing (not sure how to do same thing with Rack::Server).

app     = Rack::Directory.new ENV['HOME'] # a sample app
handler = Rack::Handler.pick %w/ thin webrick /
handler.run app do |server|
  # handler.run yields a server object,
  # which we shutdown when ocra is packing
  if ocra_is_packing # replace with proper condition
    Thread.new { sleep 10; server.shutdown }
  end
end

您可能需要做其他事情(访问服务器等)才能让 ocra 打包适当的依赖项.

You may have to do something else (access the server etc.) to have ocra pack appropriate dependencies.
