I just updated to the latest Julia 0.4 nightly to try out package precompilation and received some strange warnings when using Images immediately after running Base.compile(:Images).

From what I can tell, the package loaded properly, and the errors did not re-occur when I started a new Julia REPL and ran using Images there.

Steps:

  • Downloaded the latest Julia nightly
  • Started a REPL at the command line
  • Pkg.update()
  • Base.compile(:Images)
  • using Images

Here are the errors:

Should we add a message to the end of Pkg.update() telling the user they need to restart Julia?

Is there a way to make it so that the user wouldn't have to restart?

call workspace()

All the ambiguity warnings are a consequence of #12115 (recently merged). We're still noodling over how to fix them.

Re-using a package after a call to workspace() still triggers the errors:

oh right. i forgot i put some code into workspace() that specifically inhibits this. i guess it might be worth revisiting that.

The errors about uuid mismatch are a dup of #12508.

should be much improved by #18150. although we might still want to add a message to the end of Pkg.update suggesting restarting the REPL to pick up the changes
