Random "all goroutines are asleep - deadlock!" on a build

btakita commented 7 months ago

I have not seen this error before & cannot reproduce. The project I ran this on is https://github.com/btakita/briantakita.me-dev

git clone git@github.com:btakita/briantakita.me-dev.git
cd briantakita.me-dev
git submodule init
git submodule update
bun i
app--build

It uses rebuildjs, relysjs, & @rebuildjs/tailwindcss...all of which I wrote. The rebuildjs core is a reactive build, which include throw new Cancel, which cancels the existing build process a reactive memo (using rmemo, another library I wrote) starts a new build. I'm mentioning this because it's not a normal use case & it's possible some undiscovered concurrency issues can arise...as seems to be the case here.

Actually, another build is not started. There is only one call to esbuild_ctx.rebuild() on the production environment. Sorry about the misstatement above. The Cancel logic is contained within various rmemos which:

sync the concurrent browser + server builds → hold state derived from metafile.json → post-build work → modify the state → persist the new state to metafile.json.

The app build logic is in https://github.com/btakita/briantakita.me/blob/main/build.ts, where @btakita/briantakita.me is a submodule in the btakita/briantakita.me-dev project.

From an esbuild perspective, one thing that is unusual is that two concurrent .rebuild() calls occur...for the browser & server...with each build having multiple entry points.

I have the same issue here when i start the dev angular server.

I have the same issue on an angular build, @XhstormR, on a Linux Azure Pipeline build. Did you ever find out what's going on?
