If you want to save more precompile information, one option is to create a
"userimg.jl" file with which to build Julia. This is only supported for
@snoopc. Instead of calling
SnoopCompile.write, use the following:
# Use these two lines if you want to add to your userimg.jl
pc = SnoopCompile.format_userimg(reverse!(data))
Now move the resulting file to your Julia source directory, and create a
userimg.jl file that
includes all the package-specific precompile files you want. Then build Julia from source. You should note that your latencies decrease substantially.
There are serious negatives associated with a
- Your julia build times become very long
Pkg.update()will have no effect on packages that you've built into julia until you next recompile julia itself. Consequently, you may not get the benefit of enhancements or bug fixes.
- For a package that you sometimes develop, this strategy is very inefficient, because testing a change means rebuilding Julia as well as your package.
A process similar to this one is also performed via PackageCompiler.
