Webpack-dev-server: Continuous re-bundling, VALID state never reached

[mischkl]

Do you want to request a feature or report a bug?
bug

What is the current behavior?
Oftentimes when a file is changed, webpack re-bundles, says the bundle is VALID then INVALID, rebundles again, again says VALID then INVALID, and over and over. The only way to interrupt the process is to press Ctrl-C and try again.

If the current behavior is a bug, please provide the steps to reproduce.
This issue occurs when using the following configuration:
https://gist.github.com/mischkl/cf7ab4b10df9763aa698a5b885f700cd

What is the expected behavior?
After max a couple of re-bundles the status changes to VALID

Please mention your webpack and Operating System version.
Webpack: 2.1.0-beta.26
OS: Windows 7 Enterprise x64

Note that webpack-dev-server doesn't control any of the watching, so the issue can't be fixed here. You could verify this with webpack --watch.

Do you have any special characters in your path? There are a couple of known issues with this (see https://github.com/webpack/webpack/issues/2258).

It could also be the same issue as https://github.com/webpack/webpack/issues/2320.

Or it could be https://github.com/webpack/watchpack/issues/25. I also have this issue sometimes, but very rarely.

As a workaround you could use --watch-poll or watchOptions: { poll: true }

@SpaceK33z there are no special characters as in webpack/webpack#2258 and the output doesn't look like in webpack/webpack#2320. I guess it could be webpack/watchpack#25, although the files in question were not newly created...

Okay, I'm going to close this because we can't do anything about this in dev-server unfortunately.
