Input/output error

Question

I create file and show its contents inside of virtual machine using Docker:

touch file.txt
docker run \
    --rm -it \
    --volume $(pwd):/app \
    --workdir /app \
    alpine:3.6 \
    sh -c '\
        while : ; do \
            cat file.txt ;\
            sleep 1 ;\
        done \
    '

Then I change file locally:

date > file.txt

Everything is ok.

But when I change file in PhpStorm, I get an error message for about 20 seconds:

cat: can't open 'file.txt': I/O error

What is possible reason of this behaviour and how can I diagnose it?

(Docker 17.10, VirtualBox 5.1.30, PhpStorm 2017.2.4)

Answer 1

Try disabling "safe write" option in PhpStorm settings: Settings/Preferences | Appearance & Behavior | System Settings --> Use "safe write"...

With that option enabled IDE writes into a temp file first (e.g. file.__temp_jb__) and only then renames it into the actual target (file.txt).

It looks like such manipulation (original file gets deleted and replaced by another one) somehow conflicts with your script.
