How to shutdown daemon completely in code or clear the memory of it. #2991

Open zyzhangyang opened 8 years ago

Version/Platform/Processor information (from ipfs version --all):ipfs version --all

Type (bug, feature, meta, test failure, question):feature Area (api, commands, daemon, fuse, etc):daemon Priority (from P0: functioning, to P4: operations on fire):P3

Description: I have integrated ipfs to mobile client by modifying the main entry to api mode.Now I have to shutdown damon,because ios will suspend the app after it enters background several minutes and ipfs will not work on entering foreground. I get the IpfsNode on daemonfunc,call IpfsNode.close() to close daemon,daemon will return,and I can retart daemon.But the memory will increase after retart daemon everytime. So I want to find methods to shutdown daemon completely,and can reduce the memory of ipfs.

we havent put much effort yet into mobile, soft restarts like this are going to be very important, as well as a 'background mode' option.

What does memory usage look like for you? 100MB? 200MB?

zyzhangyang commented 8 years ago

@whyrusleeping First I start daemon,the memory usage is about 60MB,after restart daemon every time,it will increase about 40MB,and it will reach 200MB very easy. So I want to know how to modify source code to close daemo completely and release memory?

@zyzhangyang how are you interfacing with the daemon? as a subprocess, or are you embedding go code?

zyzhangyang commented 8 years ago

@whyrusleeping I modify the main.go in cmd/ipfs to a lib,then compile the ipfs to a framework by using go bind,and then I start a thread to start daemon in ios. Call other ipfs interface in other thread.

Can you get me any of the profiling information discussed in the debug guide ?

zyzhangyang commented 8 years ago

@whyrusleeping The attach file is the debug info,please see would it help? ios_ipfs_debug_info.zip

Can you share your code for ios-ipfs?
