Hi @Lord-Y
Thanks for this and for splitting the original larger PR.
I've just synced this locally and am seeing a number of test failures.
In devutil
the tinygo
test is failing with:

Two things are strange about this:
I have manually installed tinygo v0.33.0
$ tinygo version
tinygo version 0.30.0 linux/amd64 (using go version go1.21.4 and LLVM version 16.0.1)
but the failure is trying use a docker image for tinygo v0.22
. So far I've not worked out why or how this is occurring.
I saw the same failure with tinygo v0.22 FWIW.
Also I am on the current version of go (v1.21.4) so I have the changes to the format to the version
in the go.mod
line to support a versioned toolchain, which AFAIK needs the form v.X.Y.Z.
The wasm-test-suite

2023/11/24 13:14:39 ERROR: encountered exception 'Uncaught (in promise)' (136:64478)
Which then leads to a test timeout, due to the uncaught exception failure.
So ATM none of the tinygo
tests are passing.
The simplehttp
package is failing with:

But this one is trivial to fix.
Are you also seeing these?
We want to keep all of the tests building at each PR stage.
Owen
Sorry I forgot to say....
In general the PR itself looks to be fine. :smile:
We will need to have a bit of a debate about returning errors vs panic'ing - in general I think it's ok if a function in a tool package panics, but not in package used by a framework or server, which seems to be the case here.
@owenwaller Instead of the bulk PR that I previously did, this is a step by step PR. So you need to use go1.17
and tinygo 0.22
. All tests will then be successful.
So @owenwaller you need to do:
go install golang.org/dl/go1.17@latest
go1.17 download
go1.17 test XXX
Hi @Lord-Y
Ah ha, yes downgrading to go1.17 from g1.21.4 does indeed make the tests pass (also with tinygo v0.22).
This is a question for @bradleypeabody
Should we:
Personally I prefer option (3), we can then combine the PRs locally and push the merged version back as a new release.
@Lord-Y @bradleypeabody is on thanksgiving so he might be slow to respond. But have you any idea how much work it would be to do option (3)? Personally, I think the quicker we get vugu building with a current version of Go the better, as it is unreasonable to ask folks to downgrade their go tool chain to do this.
Owen
@owenwaller as said in https://github.com/vugu/vugu/issues/246#issuecomment-1817900990 , my plan was to have PRs 252 to 256 merged. And only then make a PR for the upgrade to golang 1.21.x. I almost finished the requirements last sunday but didn't have the time to continue this week. So I'll continue this week-end.
@owenwaller So all my tests are passing with go 1.21.4
. I'll wait for the PRs 252 to 256 merged before creating the new one.
Hi @Lord-Y
OK thanks. So if we can get PR #252 and #256 merged in first, can PR's #253, #254 and #255 can all be merged after the new PR that updates go to v1.21.4?
@bradleypeabody I think both of these PR's 252 and 256 are fine. If you agree can you merge these in, so they don't block the new PR that will update go to v1.21.4 (which we can't build vugu with ATM). We can then merge in the other changes.
@Lord-Y if you have the new PR that does the go upgrade finished, can you open a new PR for that so we can review it?
Okay, I'm going to go ahead and merge these in just to get the flow going. There are some test failures, please have a look at those and submit another PR to fix.
@bradleypeabody @Lord-Y
Given that this change is merged, I am going to close this PR.
Can you please be specific in the new PR what tests have failed?
Thanks
As said in my last comment in PR https://github.com/vugu/vugu/pull/248, here is the 1st of many series of PR. This PR goes with https://github.com/vugu/vugu/issues/246 requirements.
I usually remove every unused functions/variables for a cleaner code. I didn't do it this time so I add
//nolint:golint,unused
tag. Tell me if you want me to delete them or not.I'm not sure what you wanted to do https://github.com/Lord-Y/vugu/blob/057f77f040a6752b26d472deff9d9023b379c82e/tinygo-dev/testpgm.go#L19 with
