fatal error: concurrent map read and map write #2549

rdwatters · 2016-10-10T16:32:53Z

Left this on the forums as well. Getting this at a rate of almost every other save/livereload at this point. Unfortunately, the repo is private, but I can invite if necessary for a more comprehensive look at the code. Here's a link to the gist:

https://gist.github.com/rdwatters/ab7d3226fff97c7b432e5264fab57466

bep · 2016-10-10T16:40:35Z

Probably same as #2224. If you could invite me so I could have a look that would be great.

rdwatters · 2016-10-11T06:26:08Z

Done and done @bep. Thanks much.

bep · 2016-10-11T06:40:04Z

Thanks, @rdwatters -- I can reproduce with this one, which means I can figure it out.

bep · 2016-10-11T07:09:01Z

@rdwatters in your case it is the nested partial invocations that makes the race happen:

taxonomy.html -> partial -> partial

That should be enough to create a test case.

rdwatters · 2016-10-11T13:11:19Z

@bep. Just to make sure I follow. Is this an example?

https://github.com/rdwatters/digitalcaporg-redesign/blob/master/layouts/partials/components/article-listing.html

That's too bad if it's the nested partials that are causing the issue since the partials/components/title comes in awfully handy.

That said, I haven't had a single issue at build time (I'm using Netlify for CD), but the local deve definitely seems to be getting worse.

bep · 2016-10-11T13:15:42Z

Removing the nested partial makes the rebuilds stable -- but that is just a symptom ... or something. We'll fix this. Regular builds seems to be stable with your site.

bep · 2016-10-11T13:16:16Z

Is this an example?

Yes.

rdwatters · 2016-10-11T14:39:46Z

Great. Thanks much for looking into this. Should I post an issue elsewhere (perhaps add to the previous golang thread? I ask because I use that heading partial all over the place. At this point, I'm not sure it's worth extracting just to prevent the panic during dev.

See #2549

bep · 2016-10-11T18:31:08Z

No, I will try go boil it down to a simpler reproduction and post it at Go stdlib. If it is an issue we can probably work around it on Hugo side by adding a mutex.

bep · 2016-10-11T19:17:41Z

The Go issue:

golang/go#16101

rdwatters · 2016-10-11T19:31:49Z

Thanks for the due diligence on this @bep. I offered the repo on the Go issue thread as well.

bep · 2016-10-13T09:16:46Z

OK -- now I have this issue on my site ass well ... pain in the ass. I think the cause of it was adding the second block to my base template.

bep · 2016-10-13T12:22:41Z

The good news: I have a small reproduceable (I will try to make it even smaller) for the Go team -- the bad news is I don't see a workaround, yet ...

This was breaking Hugo. See gohugoio/hugo#2549

rdwatters · 2016-10-17T04:07:07Z

Saw that workaround offered by cespare on the other thread. Glad it's been added to the milestones. I'm cool with pressing up/enter in the terminal each time it panics until v18. Cheers.

bep · 2016-10-17T07:55:54Z

Or you could build from source ...

rdwatters · 2016-10-17T15:48:31Z

Or you could point out the obvious, which I should already know. Haha. Thanks!

i'm obtaining the same error in a random way, as you can see, three hugo compilation runs fine , but another compilation raise the error.

I'm getting this same error when attempting to build using v0.75.x on AWS Codebuild (but strangely not when using v0.75.1 locally on macOS). Installing Hugo using the following commands:

wget https://github.com/gohugoio/hugo/releases/download/v0.75.1/hugo_extended_0.75.1_Linux-64bit.deb
dpkg -i hugo_extended_0.75.1_Linux-64bit.deb```
