module http_util is not available in elixir 1.15.2

Elixir and Erlang/OTP versions

Erlang/OTP 26 [erts-14.0.2] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [jit] [dtrace]

Elixir 1.15.2 (compiled with Erlang/OTP 26)

Operating system

MacOS Ventura v13.4.1

Current behavior

I tried to upgrade my project to the new elixir version and ran into an issue with a dependency Sobelow, which uses :http_utils.timestamp internally, throwing ** (UndefinedFunctionError) function :http_util.timestamp/0 is undefined (module :http_util is not available). I reproduced the behaviour (that the module does not exist in the new version) in a minimal example below:

mix new test_elixir_version
iex -S mix
Compiling 1 file (.ex)
Generated test_elixir_version app
Erlang/OTP 26 [erts-14.0.2] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [jit] [dtrace]

Interactive Elixir (1.15.2) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> :http_util.timestamp
** (UndefinedFunctionError) function :http_util.timestamp/0 is undefined (module :http_util is not available)
:http_util.timestamp()

Expected behavior

When running the same code in the project but with elixir 1.14.2, the module / function is available.

iex -S mix
Erlang/OTP 26 [erts-14.0.2] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [jit] [dtrace]

iex(1)> :http_util.timestamp

Sobelow needs to declare :inets as a dependency, which is where that module is defined. Although in their case, it is probably best to replace :http_util.timestamp by System.os_time(:milliseconds).

This issue also seems to address this: nccgroup/sobelow#143 - but yeah, there is probably no need to load http_util for this. :)

Missed that they had a pull request for that in the works. Thanks!

PR is merged in, new version of Sobelow is getting pushed out to Hex.pm here in a few - sorry for the delay and thanks for the patience!
