workaround wrong paths reported for stdlib functions #32763

KristofferC · 2019-08-02T00:25:24Z

Not really clean to special case it just ofr less and edit but that is where people seems to encounter this issue the most. The workaround could potentially be put in find_source_file but that is a bit more "invasive".

This is also kinda hard to test. I tested it by evaluating this into InteractveUtils in a released julia.

Fixes #26314

Maybe add this for @which too?

Something holding this from being merged? Would be nice to have this issue fixed.

Something holding this from being merged? Would be nice to have this issue fixed.

I improved the implementation a bit but should be good to go now.

Tried it locally with the executable built by the buildbot and @which, @edit and @less work well with stdlib functions now.

vtjnash · 2019-10-15T15:27:17Z

Yeah, going with something, anything, is better than being always broken.

+# This function does the method location updating
+function updated_methodloc(m)
+    file, line = invokelatest(methodloc_callback[], m)
+    if file !== nothing && isdefined(@__MODULE__, :Sys)


Suggested change

if file !== nothing && isdefined(@__MODULE__, :Sys)

if file !== nothing && Sys.BUILD_STDLIB_PATH != Sys.STDLIB

Is Sys ever not defined?

And should we put this inside default_methodloc, or do we want to do this unconditionally?

It's not defined when this function gets defined and I was worried if there was some error before Sys gets defined then it would crash when trying to print some method.

I think we want to do this unconditionally.

Can this still make it into 1.3 or does the feature freeze prohibit it?

KristofferC · 2019-10-16T09:23:14Z

It will not make it into 1.3.0 for sure. Maybe 1.3.1.

rapus95 · 2019-10-16T09:40:36Z

Btw as this request is called workaround, I guess you'd not call it the idiomatic way.
Would it generally make sense to use the pathof(module) function to determine the path of the module where the function was defined and then resolve the path relative to that?

KristofferC · 2019-10-16T10:00:22Z

I dunno... If it works, it works:P

I did some fixups here @vtjnash

Does Pkg\src\Operations.jl need an update as well?
I get the wrong paths as well when interacting with the Package Manager.

KristofferC · 2019-10-16T17:21:51Z

I guess @info embeds the full path as well at macro expansion time. But that's for another PR.

rapus95 · 2019-10-23T11:09:24Z

Sad that it won't make it into 1.3 even though it is already merged 🙈

KristofferC · 2019-10-23T11:36:29Z

Could be put into 1.3.1 if it doesnt cause any problems on master.

I'm begging for it! This has been bugging me for way too long now. 😊

KristofferC · 2020-01-02T20:41:50Z

I have my script set to ignore backport labels that also has a triage label because we said we would triage backports at some point. This doesn't seem to happen though so the result is that PRs (like this) just get forgotten. I'll just backport stuff that includes the triage label as well.
