WSL and file modification detection / livereload troubles?

support
1

Hi

I try to develop my website with Hugo and meet some troubles.
I try to use it with postcss and tailwindcss. Project is in early stage, nearly out of the box…

I have a laptop running on manjaro and hugo works fine

I have a desktop running on windows 10 and develop my web sites with ubuntu 20.04 in WSL2, code edition is made with VSCode in Windows… and Hugo does not like it ! Page generation is veeeery slow (30 / 50 seconds) and most of the time file system modifications are not detected and of course livereload is not triggered.

Any clue ?

Sooo… let’s assume you are on my side and I am on your side: Would you want me to add information about any code and configuration of your setup? Because if not, you would be wrong :wink: From your description nobody can help you. Please post your repository and somebody will have a look into it.

Hi @davidsneighbour thank you.

Answering to you will be fast as i have nearly made nothing until yet

I made ‘hugo new site test-site’ , then pickup this theme https://github.com/dirkolbrich/hugo-theme-tailwindcss-starter , activate theme, copying sample site… and that’s where i am :slight_smile: no other code than this

Generation takes several ms in manjaro (livereload ok; site is ok) and nearly 40 to 50 seconds in WSL 2 (no livereload update; site is ok though not updated)

Do you want some logs or something more ? Because at this stage i don’t know what to look for. BTW I suspect the WSL

Windows 10 Pro build 20257.fe_release.201106-1554
Ubuntu 20.04.1 LTS in WSL version 2
Hugo Static Site Generator v0.78.2-959724F0 linux/amd64 BuildDate: 2020-11-13T10:08:14Z

Does WSL print anything when running hugo server? I am suspecting WSL too, but I would expect some kind of notice about “starting up the engine”. Can you try to run the following command and copy paste everything that comes up:

hugo server --minify --disableFastRender --i18n-warnings --navigateToChanged  --templateMetrics --templateMetricsHints --verbose --verboseLog --path-warnings --buildDrafts --buildExpired --buildFuture --watch --enableGitInfo --forceSyncStatic --log true --logFile hugo.log --verbose

That’s my go-to-verbose-mode hugo server command. Some things might be unimportant, but template metrics and verbosity are good for a start. We should see from the timestamps where it sleeps.

Here is the output (it’s the same after removing --enableGitInfo that causes the error)

I also read this in reddit about WSL 2 : They changed the file sharing protocol, from using they own custom developed protocol to using the 9P protocol, which at this time might not support file changes event.. I will investigate

I found out the problem ! :slight_smile:

Let me explain

My web projects are stored on a D: Windows NTFS hard drive, in the WSL this drive is auto mounted as /mnt/d , I simlinked this in my home for quick access. THAT is what bothered Hugo

Now i copied my site in a pure Linux folder in my home and that is working perfectly :slight_smile:

In fact, it’s more a livereload issue with the 9P protocol than a Hugo issue :slight_smile:
