[webpack --watch + web-ext start] Unexpected packet from actor root (Application Update Service Helper) #1092

Open osdiab opened 7 years ago

osdiab commented 7 years ago

Is this a feature request or a bug?

Bug

What is the current behavior?

I am developing an extension. It uses webpack@3.5.5 to compile a TypeScript project to JS scripts specified in manifest.json. For the development workflow I use the concurrently@3.5.0 library to run the following command:

concurrently 'webpack --watch' 'web-ext run'

This starts up properly, but pretty frequently, the Firefox browser to boots up closes automatically and this error shows up in the terminal:

What is the expected or desired behavior?

Version information (for bug reports)

node --version && npm --version && web-ext --version
v8.2.1
5.4.2
2.0.0

Thanks in advance!

Hi. Thanks for the bug report. Could you attach a log generated with web-ext run --verbose?

As a side note, you may wish to ignore your source files so that only the final webpack-built files will trigger web-ext to reload your extension. However, that may not be related to this bug.

I added my source files to be ignored, but the error still occurred; here's the verbose error:

Thanks for your prompt help! I'm traveling around so I just got around to posting this now. [0] is the output for my webpack job, and [1] is the output for web-ext --verbose.

And also to be clearer, this doesn't happen everytime—just frequently enough to be a pain; sometimes it happens almost every time/every other time I save my source and therefore trigger Webpack to regenerate my code again but for instance right now it's only happening once in maybe 10-15 saves or so, I don't really know why the frequency of the error varies so much.

sneakypete81 commented 6 years ago

I see this behaviour too on both Mac and Windows, usually failing but occasionally succeeding. It appears to be if a file changes at some critical point while Firefox is starting up - if I add a fixed delay to ensure webpack doesn't output anything while web-ext run is starting, it never seems to fail.

See also #1069.

Firefox version: 56.0.1 (64-bit) OS and version: Win10 RS1

node --version && npm --version && web-ext --version
v6.10.1
3.10.10
1.9.1

Thanks for the verbose log. It looks like 'Application Update Service Helper' is maybe causing the issue but things like that are supposed to be disabled by web-ext. Maybe some configuration for it changed.

Also, maybe we should not throw an error for unexpected actor messages. I'll have to think about the implications of ignoring errors though.

kumar303 commented 6 years ago

Fixing this may require porting from firefox-client to https://github.com/saucelabs/foxdriver (or something)
