[GitHub] [couchdb] jjrodrig opened a new pull request, #4726: Unlock build using Elixir 1.15
jjrodrig opened a new pull request, #4726:
URL: https://github.com/apache/couchdb/pull/4726
## Overview
Elixir 1.5 introduces some changes in the compilation process tha affects to
the execution of our test suite. The problem has been reported here #4706
It seems that we are facing one of the incompatibility problems documented
in the Elixir 1.15 release notes
> Potential incompatibilities
Due to the code path pruning, if you have an application or dependency that
does not specify its dependencies on Erlang and Elixir application, it may no
longer compile successfully in Elixir v1.15. You can temporarily disable code
path pruning by setting prune_code_paths: false in your mix.exs, although doing
so may lead to runtime bugs that are only manifested inside a [mix
release](https://hexdocs.pm/mix/1.15/Mix.Tasks.Release.html).
Previous to this PR, if we try to run the elixir test suite with Elixir
1.15, the following error appears in any test that uses `jiffy`.
```
> make clean couch elixir
1) test Basic reduce functions (ReduceTest)
test/elixir/test/reduce_test.exs:16
** (UndefinedFunctionError) function :jiffy.decode/2 is undefined
(module :jiffy is not available)
stacktrace:
(jiffy 1.0.9) :jiffy.decode("{\"ok\":true}\n", [:return_maps])
```
This PR indroduces the suggested temporary fix in the `mix.exs` by adding
`prune_code_paths: false` to the build config. With this change we can use
Elixir 1.15 in our build process. I've tried to find the problem with our
dependency declaration without sucess. This should be a temporary solution
until we find the root of the problem.
This PR introduces a second change in the Makefile clean target by adding
aditional cleanup for elixir build artifacts.
## Testing recommendations
- Install Erlang >= 24
- Install Elixir 1.15
- `make clean couch elixir`
The elixir test suite should run without problems. Then check the cleanup.
- `make clean`
- `find . -name "_build"` (No _build folder should be found)
- `MIX_ENV=integration mix deps` (should inform that every dependency needs
to be compiled/updated)
