:tzdata_release_updater terminating, argument error

[matteosister]

I'm on elixir 1.2.2, my deps are:

defp deps do
  [
    {:amqp, ">= 0.1.4"},
    {:ecto, "~> 1.1"},
    {:mariaex, "~> 0.6"},
    {:ex_statsd, ">= 0.5.1"},
    {:exrm, "~> 1.0"},
    {:poison, "~> 1.0"},
    {:credo, "~> 0.3", only: [:dev, :test]},
    {:dialyxir, "~> 0.3", only: [:dev]},
    {:timex, "~> 2.0"},
    {:timex_ecto, "~> 1.0"},
    {:httpoison, "~> 0.8.3"}
  ]
end

When I run the project (for example with iex -S mix) I get this after some seconds:

12:48:10.781 [error] Task #PID<0.3269.0> started from :tzdata_release_updater terminating

I tried deleting the _build folder with no luck...

[matteosister]

the problem seems related to the last version of tzdata: 0.5.7
the 0.5.6 version works!

[matteosister]

the downgrade to 0.5.6 makes it work also on 0.5.7...after upgrading again now it works. 😓

I'm not sure what the issue is. There have been issues with Timex. I recommend using Calendar: https://github.com/lau/calendar

[benwilson512]

Same issue here, and I'm using Calendar.

[benwilson512]

rm -rf _build solved this for me.

[lau]

Is this is development mode or does it happen when deployed to a server?

Did you have this config setting set? config :tzdata, :data_dir, "/some/path/here"

[benwilson512]

At the moment merely development, and no I do not have any such config set.

From the line numbers, looking at the code, it looks like it tries to open a file latest_remote_poll.txt but it can't. I will try to see if I can provoke the same error.

[benwilson512]

Thanks! I continue to be very happy with Calendar by the way, great work.

[lau]

Thanks, I appreciate that.

I got the same issue, I have :calendar, "~> 0.14.0" as a dependency. Resolved by specifying :tzdata, "~> 0.5.7" in the list of deps which updated the tzdata (ETS table and its related file):

[debug] Tzdata polling for update.
[debug] Tzdata downloading new data from https://www.iana.org/time-zones/repository/tzdata-latest.tar.gz
[debug] Tzdata data downloaded. Release version 2016d.
[info] Tzdata has updated the release from 2016c to 2016d
[debug] Tzdata deleting ETS table for version 2016c
[debug] Tzdata deleting ETS table file for version 2016c

I removed tzdata from the list of deps and now I no longer get the errors. I hope this helps in spotting the issue.

A new version 0.5.8 has just been release. It has improved error handling for errors related to latest_remote_poll.txt.
