- %% Regression test for https://github.com/rebar/rebar/issues/249
- %%
- %% Root cause: We didn't have per-project .rebar/erlcinfo but just one in
- %% <base_dir>/.rebar/erlcinfo.
- %%
- %% Solution: Ensure every project has its own .rebar/erlcinfo
- %%
- %% For the bug to happen, the following conditions must be met:
- %%
- %% 1. <base_dir>/rebar.config has erl_first_files
- %% 2. one of the 'first' files depends on another file (in this
- %% case via -include_lib())
- %% 3. a sub project's rebar.config, if any, has no erl_first_files entry
- %%
- %% Now because erl_first_files is retrieved via rebar_config:get_list/3,
- %% base_dir/rebar.config's erl_first_files is inherited, and because we had
- %% a shared <base_dir>/.rebar/erlcinfo instead of one per project, the
- %% cached entry was reused. Next, while compiling the sub project
- %% rebar_erlc_compiler:needs_compile/3 gets a last modification time of
- %% zero for the 'first' file which does not exist inside the sub project.
- %% This, and the fact that it has at least one dependency, makes
- %% needs_compile/3 return 'true'. The root cause is that we didn't have per
- %% project .rebar/erlcinfo. For <base_dir>/.rebar/erlcinfo to be populated,
- %% base_dir has to be compiled at least once. Therefore, after the first
- %% compile any compile processing the sub project will fail because
- %% needs_compile/3 will always return true for the non-existent 'first'
- %% file.
