Detailed coverage is broken with Vala #799

Open arteymix opened 8 years ago

It seems like gcov cannot locate generated C sources correctly.

I'm getting the same here, just tried with https://github.com/GNOME/gnome-calculator but it fails randomly (like if the .c file isn't ready).

Also the generated files don't point to the actual .vala source, but to the .c code (while .c files includes #line directives properly).

Same issue for me. As shown in this example repo, ninja coverage-text can't bind generated c files with vala sources.

I'll be happy to dig into meson sources to fix this issue, any help will be appreciated to support me in that task...

Same issue here.

If I comment out the custom target below, it configures, but no coverage is actually generated when i do ninja coverage.

g_ir_compiler = find_program('g-ir-compiler', required: false)
if g_ir_compiler.found()
# the meson docs are incorrect on this

    install: true,
    install_dir: get_option('libdir') / 'girepository-1.0',
  )

Before I upgraded, with meson 0.54.0 (i think), it was generating coverage, but only for one of the .c files generated by valac.

cxw42 commented 3 years ago

Also the generated files don't point to the actual .vala source, but to the .c code (while .c files includes #line directives properly).

If you run valac -g, you will get #line directives pointing into the vala source, for generated lines that directly map to .vala lines. The coverage data will be a mix of .vala and .c files, but it works reasonably well in my experience.
