If people wish to opt out they can use `DISABLE_BOOTSNAP = 1`
Bootsnap is production ready and was tested on our production
servers for safety.
Promoting it now so it is enabled globally.
Will result in faster application boot
Adds new hidden site settings for rate limits:
30 for logged in users, 15 for anon
Adds an anon cache for searching, caches results of searches for 1 minute
Discourse needs a bunch of data preloaded before it can start up.
Normally we throw blobs of this into the HTML document that is requested
but in some cases that's awkward to retrieve.
For example with Ember CLI you have a separate javascript application
that needs to make its own HTML.
This API endpoint returns a JSON object with all the data Discourse needs to
bootstrap and start up.
Bootsnap is designed to work in production per:
https://github.com/Shopify/bootsnap
Over the years we have seen very few issues with it, none of which
were corruption.
This allows us to enable bootsnap in production
Having bootsnap enabled means that we can speed up deploys by
about 5 seconds per server. It also means a lot less waiting for
various production rake tasks and so on.
In some restricted setups all JS payloads need tight control.
This setting bans admins from making changes to JS on the site and
requires all themes be whitelisted to be used.
There are edge cases we still need to work through in this mode
hence this is still not supported in production and experimental.
Use an example like this to enable:
`DISCOURSE_WHITELISTED_THEME_REPOS="https://repo.com/repo.git,https://repo.com/repo2.git"`
By default this feature is not enabled and no changes are made.
One exception is that default theme id was missing a security check
this was added for correctness.
The risk here is that the database for one site goes down in the multisite setup and we drop everything to readonly mode. However, I discussed this with Sam and we agree that one database having problem is very rare. Most of the time, it is the entire DB cluster that goes down.
* FEATURE: notify admins about old credentials
Security and API keys should be renewed periodically.
This additional notification should help admins keep their Discourse safe and secure.
* DEV: To be pedantic, there is more than EMBER in there now
* DEV: Use less globals. Have `Discourse` start in an initializer
* DEV: Remove another global
