open /dev/null: too many open files about realize

[emilgpa]

The error is raised in build.Run() from GoInstall(), GoFmt() and GoBuild() methods

@DasHaus how many files do you have? could be a problem of the fsnotify package.

@DasHaus thanks for the tip, we'll investigate as soon as possible how fresh work.

Probably it is a problem related to operating system limits as you can read in the last FAQ of fsnotify. @DasHaus have you ran realize and fresh at same time? In this case you may have reached the maximum limit of files that can be watched.

[emilgpa]

@asoseil I don't know. How can I know it?
@conventi No, only realize. There is any possibility to know when files is trying to open realize?

[asoseil]

In your config yaml, under the Watcher obj, add "preview:true"

[emilgpa]

I changed to "github.com/howeyc/fsnotify" package (the same that uses fresh), then I execute the command go install in the realize package and try it but the result is the same...

@DasHaus if you are on a MAC OS X or a GNU/Linux system you can count the number of files (recursively) by executing find . -type f | wc -l form working directory. Let us know!

[emilgpa]

@conventi I'am on Mac OS X. Sorry by not saying it before. The total is 3092 files.

@DasHaus you have 3093 files that you want to watch (have you cd into right directory)? Sorry if I ask but we have to retrive all informations to debug realize. Thanks for help!

[emilgpa]

Yes. Is the total files that I want to watch.

Ok thanks a lot! At this point this is obviously a bug related to realize and we will investigate into fresh package to resolve this issue.

[emilgpa]

OK, thanks you!

[emilgpa]

Ok. I found a solution. In the function routines(), I added to the end wg.Wait(), and now it works.

routines := func() {
        channel = make(chan bool)
        err = p.fmt()
        if err == nil {
            wr.Add(1)
            go p.build()
            go p.install(channel, &wr)
            wr.Wait() // I ADDED THIS LINE AND NOW WORKS!
        }
    }

[emilgpa]

Also, inside the routines function, when an error is raised, this error is not displayed in the terminal.

@DasHaus thanks a lot for your debug. We will testing your fix and if it's ok for all our cases we will integrate it!

[emilgpa]

@conventi You are welcome. Thank you for the package. I was long time looking for a substitute for fresh!

[asoseil]

Sorry, i lost your contribute with the last merge. added back just now.
