705057955 MDU6SXNzdWU3MDUwNTc5NTU= 969 Add --tar option to "datasette publish heroku" betatim 1448859 closed 0   Datasette 0.50 5971510 3 2020-09-20T06:54:53Z 2020-10-08T23:55:59Z 2020-10-08T23:30:59Z NONE  

This issue is about how best to pass additional options to tools used for publishing datasettes. A concrete example is wanting to pass the --tar flag to the heroku CLI tool. I think there are at least two options for doing this: documentation for each publishing tool to explain how to set flags via env variables (if possible) or building a mechanism that lets users pass additional flags through datasette.

When using datasette publish heroku binder-launches.db --extra-options="--config facet_time_limit_ms:35000 --config sql_time_limit_ms:35000" --name=binderlytics --install=datasette-vega to publish https://binderlytics.herokuapp.com/ the following error happens:

``` › Warning: heroku update available from 7.42.1 to 7.43.0. › Warning: heroku update available from 7.42.1 to 7.43.0. › Warning: heroku update available from 7.42.1 to 7.43.0. Setting WEB_CONCURRENCY and restarting ⬢ binderlytics... done, v13 WEB_CONCURRENCY: 1 › Warning: heroku update available from 7.42.1 to 7.43.0. ▸ Couldn't detect GNU tar.

After installing GNU tar with brew install gnu-tar and modifying datasette/publish/heroku.py to include the --tar=/path/to/gnu-tar publishing works.

I think the problem occurs once your heroku slug reaches a certain size. At least when I add only a few 100 entries to the datasette then the error does not occcur.
