This commit adds some system specs to test uploads with
direct to S3 single and multipart uploads via uppy. This
is done with minio as a local S3 replacement. We are doing
this to catch regressions when uppy dependencies need to
be upgraded or we change uppy upload code, since before
this there was no way to know outside manual testing whether
these changes would cause regressions.
Minio's server lifecycle and the installed binaries are managed
by the https://github.com/discourse/minio_runner gem, though the
binaries are already installed on the discourse_test image we run
GitHub CI from.
These tests will only run in CI unless you specifically use the
CI=1 or RUN_S3_SYSTEM_SPECS=1 env vars.

It's very simple import script and currently imports only the following content:
* Users
* Messages as Discourse topics/posts
* Attachments
Each channel can be mapped to a category and tags. It uses regular expressions to convert formatted messages ("rich text") into Markdown used by Discourse. In the future we could convert the `blocks` attribute from each message into Markdown instead of applying regular expressions on the `text` attribute.
Various migration scripts define a normalize_raw method to do custom processing of post contents before storing it in the Post.raw and other fields.
They normally do not handle nil inputs, but it's a relatively common occurrence in data dumps.
Since this method is used from various points in the migration script, as it stands, the experience of using a migration script is that it will fail multiple times at different points, forcing you to fix the data or apply logic hacks every time then restarting.
This PR generalizes handling of nil input by returning a <missing> string.
Pros:
no more messy repeated crashes + restarts
consistency
Cons:
it might hide data issues
OTOH we can't print a warning on that method because it will flood the console since it's called from inside loops.
* FIX: zendesk import script: support nil inputs in normalize_raw
* FIX: return '<missing>' instead of empty string; do it for all methods
Before `pg` gem version 1.4.6 was loading `date` as dependency.
Looks like version 1.5.1 is not doing that anymore. Update was done here: d32709a74f
Therefore, we have to load `date` explicitly.
Previously, FETCH_HEAD would always point to tests-passed because our base docker image was configured to only fetch the tests-passed branch. Since https://github.com/discourse/discourse_docker/commit/53bbacc882, we switched to a partial clone which means that `git fetch; git checkout FETCH_HEAD` will checkout whichever remote branch is the first alphabetically. This commit makes the checkout more specific to avoid this issue.
Fixes an assumption that the PostgreSQL port will always be reachable at
the discovered host on the default port when performing the healthcheck.
Instead we should be sourcing this from the same environment variable
that the application will be using to connect to.
Defaults to the standard PG port, 5432.
There are two failure modes that can be expected - no target SRV DNS RRs
found or no healthy service available at target addresses. Prior to this
patch, there was no way to differentiate from log messages between the
two cases.
Introduce an EmptyCache exception which may be raised by either the
ResolverCache or HealthyCache. The exception message contains enough
information about where the exception occurred to troubleshoot issues.
An existing bug was fixed in this commit. Previously if a target address
changed during runtime, an old cached (healthy) address would be
returned.. The behaviour has been corrected to return the newly cached
address.
This commit implements many changes to topic and comments embedding. It
deprecates the class_name field from EmbeddableHost and suggests using
the className parameter. discourse_username parameter has been
deprecated and it will fetch it from embedded site from the author or
discourse-username meta.
See the updated code sample from Admin > Customize > Embedding page.

The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.
There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.
This bug is actually a Drupal issue where some edited posts have their `created` and `changed` timestamps set to the same value. But even when that happens in Drupal it still maintains the correct post order in an affected thread. This PR makes the Discourse importer also maintain the original Drupal comment order by sorting comments in the source DB by their `cid`, which is sequential and never changes. More details from this post onward:
https://meta.discourse.org/t/large-drupal-forum-migration-importer-errors-and-limitations/246939/24?u=rahim123
We'd like to lean on the DNS caching service for more than the standard
DB and Redis hosts, but without having to add additional code each time.
Define a new environment variable
DISCOURSE_DNS_CACHE_ADDITIONAL_SERVICE_NAMES (admittedly a mouthful)
which is a list of service names to be added to the static list at
process execution time.
For example, plugin foo may reference two services that you want to
cache the address of. By specifying the following two variables in the
process environment, cache_critical_dns will perform the lookup
alongside the DB and Redis host variables.
```
DISCOURSE_DNS_CACHE_ADDITIONAL_SERVICE_NAMES='FOO_SERVICE1,FOO_SERVICE2'
FOO_SERVICE1='foo.service1.example.com'
FOO_SERVICE1_SRV='foo._tcp.example.com'
FOO_SERVICE2='foo.service2.example.com'
```
The behaviour when it comes to SRV record lookup is the same as
previously implemented for the `DISCOURSE_DB_..` and
`DISCOURSE_REDIS_..` variables.
For the purposes of the health checks, services defined in the list _are
always considered healthy_. This is a compromise for conveniences sake.
Defining a dynamic method for health checks at runtime is not practical.
See t/88457/32.
1. Fix bug where we were not waiting for all unicorn workers to start up
before running benchmarks.
2. Fix a bug where headers were not used when benchmarking. Admin
benchmarks were basically running as anon user.
3. Disable rate limits when in profile env. We're pretty much going to
hit the rate limit every time as a normal user.
4. Benchmark against topic with a fixed posts count of 100. Previously profiling script was just randomly creating posts
and we would benchmark against a topic with a fixed posts count of 30.
Sometimes, the script fails because no topics with a posts count of 30
exists.
5. Benchmarks are not run against a normal user on top of anon and
admin.
6. Add script option to select tests that should be run.
This commit promotes all post_deploy migrations which existed in
Discourse v2.8.0 (timestamp <= 20220107014925).
This commit includes a fix to the promote_migrations script to promote
all migrations of the first version of the previous stable version. For
example, if the current stable version is v2.8.13, the version used as
a cutoff for promoting migrations is v2.8.0.
While load testing our user creation code path in production, we
identified that executing the DB statement to update the `Group#user_count` column within a
transaction is creating a bottleneck for us. This is because the
creation of a user and addition of the user to the relevant groups are
done in a transaction. When we execute the DB statement to update
`Group#user_count` for the relevant group, a row level lock is held
until the transaction completes. This row level lock acts like a global
lock when the server is creating users that will be added to the same
group in quick succession.
Instead of updating the counter cache within a transaction which the
default ActiveRecord `counter_cache` option does, we simply update the
counter cache outside of the committing transaction.

We now use Ember CLI (core/plugins) and DiscourseJSProcessor (themes) for all Ember and template compilation. This commit removes the remnants of the legacy Sprockets-based Ember compilation system.
Sprockets, and its DiscourseJSProcess-based Babel transformations, is still in use for a few assets. Ideally that will be removed/replaced in the near future.
We are already caching any DB_HOST and REDIS_HOST (and their
accompanying replicas), we should also cache the resolved addresses for
the MessageBus specific Redis. This is a noop if no MB redis is defined
in config. A side effect is that the MB will also support SRV lookup and
priorities, following the same convention as the other cached services.
The port argument was added to redis_healthcheck so that the script
supports a setup where Redis is running on a non-default port.
Did some minor refactoring to improve readability when filtering out the
CRITICAL_HOST_ENV_VARS. The `select` block was a bit confusing, so the
sequence was made easier to follow.
We were coercing an environment variable to an int in a few places, so
the `env_as_int` method was introduced to do that coercion in one place and
for convenience purposes default to a value if provided.
See /t/68301/30.
* handle polls with duplicate items

There are situations where a container running Discourse may want to
cache the critical DNS services without running the cache_critical_dns
service, for example running migrations prior to running a full bore
application container.
Add a `--once` argument for the cache_critical_dns script that will
only execute the main loop once, and return the status code for the
script to use when exiting. 0 indicates no errors occured during SRV
resolution, and 1 indicates a failure during the SRV lookup.
Nothing is reported to prometheus in run_once mode. Generally this
mode of operation would be a part of a unix pipeline, in which the exit
status is a more meaningful and immediate signal than a prometheus metric.
The reporting has been moved into it's own method that can be called
only when the script is running as a service.
See /t/69597.
Describes the behaviour and configuration of the cache_critical_dns
script, mainly cribbed from commit messages. Tries to make this program
a bit less of an enigma.
The `PG::Connection#ping` method is only reliable for checking if the
given host is accepting connections, and not if the authentication
details are valid.
This extends the healthcheck to confirm that the auth details are
able to both create a connection and execute queries against the
database.
We expect the empty query to return an empty result set, so we can
assert on that. If a failure occurs for any reason, the healthcheck will
return false.
This commit migrates all bookmarks to be polymorphic (using the
bookmarkable_id and bookmarkable_type) columns. It also deletes
all the old code guarded behind the use_polymorphic_bookmarks setting
and changes that setting to true for all sites and by default for
the sake of plugins.
No data is deleted in the migrations, the old post_id and for_topic
columns for bookmarks will be dropped later on.
An SRV RR contains a priority value for each of the SRV targets that
are present, ranging from 0 - 65535. When caching SRV records we may want to
filter out any targets above or below a particular threshold.
This change adds support for specifying a lower and/or upper bound on
target priorities for any SRV RRs. Any targets returned when resolving
the SRV RR whose priority does not fall between the lower and upper
thresholds are ignored.
For example: Let's say we are running two Redis servers, a primary and
cold server as a backup (but not a replica). Both servers would pass health
checks, but clearly the primary should be preferred over the backup
server. In this case, we could configure our SRV RR with the primary
target as priority 1 and backup target as priority 10. The
`DISCOURSE_REDIS_HOST_SRV_LE` could then be set to 1 and the target with
priority 10 would be ignored.
See /t/66045.
`ActiveRecord::Base.connection_config` has been deprecated since Rails
6.1 and was completely removed from Rails 7.
Instead we need to use
`ActiveRecord::Base.connection_db_config.configuration_hash`.
Import scripts were forgotten when we did the Rails 7 upgrade, this
patch fixes them.
