Trying to make Config Overlay work with a complex Drupal distribution

Mon, Apr 13, 2020

Drupal 8 and Drupal 9
Find It Cambridge, NICHQ, IFSI

I mean, it is working somewhat:

l sync/* | wc -l
550

versus:

l sync/* | wc -l
1062

before adding config overlay, and that’s with config snapshot still hanging around and adding 171 files versus 183 apiece.

So config overlay has reduced the config/sync export file path by a bit more than half. But after a fresh install, that number should be about 100%— there should be zero files.

Meanwhile, modules that should be enabled but aren’t…

admin_toolbar_search
google_analytics
eva (or are we dropping?)
mailsystem
metatag_open_graph
metatag_twitter_cards
sendgrid_integration
twig_tweak
views_contextual_filters_or

Some representative changes of what got re-exported:

Going to note here that Tobias Zimmermann (tstoeckler)](https://www.drupal.org/u/tstoeckler ) the maintainer of Config Overlay is being awesome, and most useful information will end up in this issue: https://www.drupal.org/project/config_overlay/issues/3127746

OK. Back to packaging config up. Working with Features for a moment.

Our feature for the install profile itself says this:

Configuration missing from active site:

node.settings

system.date

Import the feature to create the missing config listed above.

That is a lie. Both sets of configuration are in the active config— or at least they are when exported. Moreover, the configuration files in config/sync are identical to the ones in web/profile/findit/config/install except that the former has the dreaded:

core:
  default_config_hash: TL4dsl1620CB95qZ_WwWngEDKd_tSIRqKFquaFff-ag

but that’s expected in the active/exported config.

Moreover, system.theme has the same default_config_hash only in the active/config/sync version, and Features, in the same feature, sees it just fine.

Maddening!

Before config_overlay:

l sync/* | wc -l 1062

After:

l sync/* | wc -l 537

After moving workflow_buttons.settings.yml, minus the config hash junk, into our Drutopia Find It Organization feature…

l sync/* | wc -l 535

Moving one file got our count to go down by two after export. Interesting…

… but workflow_buttons.settings.yml is still there gaaaaaaahhck.

…

more success with putting views.view.moderated_content.yml into Drutopia Find It Content Management module— count went down by precisely 1, and the config file stayed gone after export!
