Library making http requests, without possibility to disabling it about tzdata

[lau]

See the "Automatic data updates" section of the readme on how to disable it.

It is a very important feature. A lot of organizations fail to be up to date because they rely on manual or processes to do it. Or they don't have any process at all for being up to date. That means that the tzdata eventually become out of date and produce incorrect results. So the idea is to have the computer do it. If the app has internet access I would recommend to leave the feature enabled.

Thanks! RTFM for me.

Would it be possible to make the hackney dependency optional for when not using the automatic data updates feature?

@thmzlt I want the automatic update feature to be on by default. I don't think that is compatible with making hackney an optional dependency. With the way hex works. If hex changes/has changed and both can be possible, let me know.

I'm interested: how are you keeping the tzdata up to date since you are not using the automatic data updates?

I am not. I'm using a library for formatting/parsing timestamps and it depends on tzdata (unfortunately most of the options for this task also depend on tzdata).

But I'd answer to your question with manually bumping the package version on each tzdata update. Obviously this is incompatible with the automatic update feature, so there are no expectations from my part. If you are interested in revisiting the merits of the feature, I can chime in.

If you are using Calendar you can specify tzdata ~> 0.1.201601
Then there is no hackney dependency nor any autoupdating.

Thank you.

Hi, @lau ! Another question, is it possible to disable initial http request? Probably I need to package initial tzdata somehow in a build process. Because otherwise it always crash without internet access, and my application will be impossible to start due to tzdata.

Hi @liveforeverx What is the problem? In the readme you can see how to disable auto updates. Then the .ets file that ships with Tzdata will be used. Or whichever file is in the dir specified in the config. See the part "Data directory and releases" in the readme.
