How to deploy Rails 4 with Capistrano 2 and precompile assets locally -

-

recently upgraded application rails 3 rails 4. in deploy scripts precompile assets locally , rsync them server(s). in rails 4 asset pipeline produces manifest- < random > .json instead of manifest.yml. since manifest files named differently, adds multiple manifest.json files shared assets directory. application picks wrong manifest file, , serves old assets.

i have read various issues related in github pull request threads:

my options seem be:

  1. don't share asset directory.

    this break old clients asking old resources.

  2. switch compiling assets on servers.

    this add complexity server.

  3. move manifest file outside of shared asset directory.

    i have since learned option removed in rails 4.

are there other solutions problem?

i found best answer after looking @ standard capistrano rails asset precompile task. added command local precompile task moves old asset manifest current release asset_manifest.json. leaves 1 manifest when new 1 uploaded.

run "mv -- #{shared_manifest_path.shellescape} #{current_path.to_s.shellescape}/assets_manifest#{file.extname(shared_manifest_path)}".compact

moving manifest-.json current_dir asset_manifest.json allows capistrano restore correct manifest file on rollback.

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
