* Fixing weighted query hotness grab logic
Prior to this commit, I carried over (albeit imprecisely) logic from the
LargeForemExperimental. That logic was to help limit articles to those
that were published since the user's latest page view.
However, I introduced a bug in this transcription. Now both
LargeForemExperimental and WeightedQueryStrategy use the same logic to
determine the oldest publication date to search for in the feed.
This resolves a bug reported where users were not seeing a large number
of items in their feed.
Incidentally, if a forem has little activity in the 18 hours, there
might be very few items in the feed.
I believe, going forward, we may need to better parameterize how many
hours is considered "stale since last page view".
Related to #15240
* Fixing implementation detail
* Extracting helper method
Prior to this commit, I had introduced a method an put it in a less
ideal module space. This commit extracts that method to a more readily
shareable module space.
I've added a few more specs to help clarify and verify behavior.
* Updating documentation
* Renaming and documenting variables/constants
* Fixing that which I broke
* Limiting feed queries
Prior to this commit, we were joining on all comments. With this
change, we're limiting the comments to reflect the same time period as
our article limit.
Hopefully this further improves the performance of the query.
* Removing unintentional puts statement
* AB Test for Feed Strategy
Adding the plumbing for performing AB Tests on the feed strategy.
You can add the environment variable `AB_TEST_SERVICE_FEED_STRATEGY` to
specify the field test to run.
For example, from the forem application home directory you can run the
following to force a strategy for all users:
```console
AB_TEST_SERVICE_FEED_STRATEGY=original bin/start
```
Forcing the strategy can significantly help with quality assurance testing.
* Adding configurable weighted feed strategy
I wrote about this exploration on [DEV.to][1]. This particular
implementation provides significant configuration options for A/B
testing.
At it's core this `Articles::Feeds::WeightedQueryStrategy` provides a
means to query articles that are relevant to the user. The
configuration helps us test and refine those values.
Further more this implementation introduces the idea of some common
interfaces for feed strategies. I'm not happy with the naming
convention but we can work to change that.
This even hints at a mechanism for administrators to configure.
Related to forem/rfcs#314, as I work towards understanding the feed
algorithm. And #15180

* Renaming AbTestService to AbExperiment
I'm loath to end any production class's filename with "test". I don't
want minitest or rspec coming along and attempting to "test" that file.
In addition, I find that Experiment better describes the concept.
Also, per conversations with Michael K, we favor nouns objects to go
in app/models and verb objects to go in app/services. That's a great
separation.
* Factoring AbExperiment into a Controller concern
I wish this could be a stand-alone module but the implementation of
field test has cases that require controller context.
* Sanitizing configurable weighted strategy cases
* Minor refactoring of coding structure
* Renaming parameter for clarity
* Renaming variable to avoid confusion
Prior to the commit, `env` is a controller variable. The injected `env`
variable didn't collide, but did create just a bit of confusion.
With this change, I'm trying to disentangle from that variable.
* Factoring AbExperiment away from mixin concern
Per discussion with Michael K, we both agree that we do not like
controller concern mixins. They can quickly complicate the legibility
of any given codebase.
This refactor provides a common and simplified interface for a Plain Old
Ruby Object (PORO) that accounts for the implementation considerations
of the underlying "field_test" controller method.
* Adding Datadog.tracer.trace around feed actions
* Adding featured_article_factor
Prior to this commit, there was no consideration for how moderators
engage with an article. This is a first nudge towards that effort.
* Removing spec
Add a spec that says yes or no we're feature testing something seems
fragile. Namely, why are we wanting to assert that as a truism.
* Helping ensure we're "tracing" the same things
From the code comment:
> Hey, why the to_a you say? Because the
> LargeForemExperimental has already done this. But the
> weighted strategy has not. I also don't want to alter the
> weighted query implementation as it returns a lovely
> ActiveRecord::Relation. So this is a concession.
* Addressing parameters for tracing function
* For weight feed query only count positive tags
A user assigns explicit points to the tags that they do or do not want
to see. This change treats the negative explicit_points as an indicator
that they don't want to see the tag.
* Adding weighted factor for privileged user reactions
* Updating comments to better clarify
* Adding additional constraint for published_at
* Updating documentation and adding logger
* Adding documentation concerning method call
* Upping logging level for experiments
See conversations in https://github.com/forem/forem/pull/15240
* Adding group by clauses to appease postgres configs
* Injecting relevant scoring method's joins
Prior to this commit, we included all of the joins regardless of the
scoring methods chosen. With this commit, we only inject joins that are
used with the commit.
What this would allow us to do is to then have some pre-cooked scoring
methods but not turn them on. Or to turn off the more expensive scoring
methods.
* Adding feature flag for feed strategy experiment
* Parameterizing featured story requiring main image
This begins to ease the resolution of #15292.
If we merge #15240, I could see setting an `Article` constant for this
value and allowing the administrator to choose the particular behavior.
Once we have insight from the product team, we can move forward with a
more comprehensive solution.
* Adding default parameter
While this is an `@api private` method, I am aligning the defaults with
it's `@api public` caller. Yes, only specs call the method, but I'd
rather not fiddle with the specs at this moment in time.
* Reworking logic to be more scannable
Prior to this commit, there existed duplicate logic between two of the
primary user feeds. This refactor introduces a new object which is
solely concerned with calculating scores to add to an article base score.
With this commit, we can introduce A/B testing by changing passing
different config values to `ArticleScoreCalculatorForUser.new`.
My suspicion is that for some of this, we might be able to better
leverage the database via select statements and SQL sums. However, that
is presently outside of what I'm prepared to tackle.

* Removing state change and unused method
Prior to this commit, the `@comment_weight` value would change. This is
not ideal as depending on the call sequence, can notably change the
output. I suspect this state change occurred so as to not alter an
underlying spec.
What this change does is remove the state change, removes a dead method,
renames a method (to the dead method name), and leverages
parameterization to better test a spec that was brittle based on
possible state changes.
I believe, from a logical stand point, that this change does not impact
the functionality nor the actual logic that is part of the production
call path.
* Marking methods as @api private
The goal is to highlight that we really shouldn't be calling these
outside of their contained class. Ideally, I'd love to make them
private methods, but there are specs and would prefer to not use
`__send__` to change those specs.
This is a noop change.
* Renaming method to refelct returned param order
Prior to this commit the "default_home_feed_and_featured_story" returned
an array of `[featured_story, default_home_feed]`. The method name and
the order of the returned values were misaligned. This change helps
align the method name and the order of those returned values.
Note, methods such as `each_with_index` have an `element, index`
parameter order.

* Optimize Article.published scope
The index on `articles.published` is not being invoked due to lack of
diversity in the values in that column (it only has 2 possible values
because it's a boolean).
The index on `articles.published_at` is extremely diverse and will be
invoked any time it can reduce the scope of a query by an order of
magnitude or more.
On DEV, this does not change the row count for the scope:
irb(main):001:0> Article.where(published: true).count == Article.where(published: true).where(Arel.sql("published_at < now()")).count
=> true
The query plan for the `Articles::Feeds::LargeForemExperimental` service
invoked in the `Stories::FeedController#show` endpoint goes from this:
Planning Time: 0.271 ms
Execution Time: 329.258 ms
to this:
Planning Time: 0.330 ms
Execution Time: 0.468 ms
This is a reduction in query time of 99.7%
* Set published_at in articles factory
An article that is published should always have a `published_at`
timestamp
* Use Time.current for Zonebie
* Add clarifying comment to Article.published scope
* Generate timestamp in Ruby instead of SQL
I think using transactions for specs was interfering with comparing
timestamps generated in SQL, so this commit generates the timestamp in
Ruby.
* Move published_at outside of the transient block
This was causing articles to be marked as `published_at` right now even
if `published_at` was specified in the `FactoryBot.create` call.
* published_at: nil is no longer the factory default
* published_at is no longer nil by default
* published_at is no longer nil by default
* We didn't actually want to clear this published_at
This was intentionally left out to show that published_at does not get
cleared when we flip published true->false.
