chore: Improve DX for building the app locally (#18784)
After upgrading `react-native` to `0.72.5` we frequently started seeing the _red screen of death_ on both `Android` and `iOS` simulators right after the app was built and installed.
This used to happen because our workflow required us to do the following :
- `make run-clojure`
- `make run-metro`
- `make run-ios` OR `make run-android`

The problem with this approach was after `metro` was started the `iOS`, `Android` build step would change the files that `metro` couldn't handle and hence metro would go out of sync.
The quick fix back then was to restart `metro` terminal and to open the app again from the simulator.
This was however not a good DX.

This commit fixes that.
We no longer rely on `react-native` cli to generate and deploy debug builds on simulators. We take control of the process via our own script. The new workflow introduced in this commit will first build the app, then install the app on the simulators and then start metro terminal. When `metro` is successfully running the script will then open the app.

The new workflow now is :
- `make run-clojure`
- `make run-ios` OR `make run-android`

Run integration tests separately from unit tests (#18304)
- make test still exists, so if you have been using it, as well as make
  test-watch, they should all work exactly the same.
- [Changed] As part of the check stage, Jenkins will run Lint and Unit Tests
  in parallel. Integration Tests run later because running them at the same
  time as Unit Tests caused errors.
- [Added] "make unit-test" and "make unit-test-watch" run unit tests only.
  Watching all unit tests is faster now because we ignore integration tests and
  we only compile shadow-cljs :mock target once. We are at approximately 10-15s
  to re-run all unit tests after saving a watched file, depending on your
  hardware. If you change mocks.js_dependencies.cljs, you must re-run the make
  target.
- [Added] "make integration-test" and "make integration-test-watch" run
  integration tests only. These are much slower than the unit tests.

Improve test failure readability (#18049)
Problem: failed equality checks as in "(is (= expected actual))" will give a
single, long line of output that for anything but the simplest data structures
is unreadable by humans, and the output doesn't give a useful diff.

Solution: use library https://github.com/nubank/matcher-combinators and its test
directive "match?" which will pinpoint where two data structures differ. Then,
instead of "(is (= ...", use "(is (match? expected actual)". It works
beautifully.

The library offers other nice matchers, but the majority of the time match? is
sufficient.

Can we use another test runner like Kaocha? kaocha-cljs2
(https://github.com/lambdaisland/kaocha-cljs2) would be able to print better
test errors out of the box, among other features, but I have no clue if it would
work well or at all in our stack (in theory yes, but it's a larger piece of
work).

Document how to auto-format Clojure files in VSCode with zprint (#17719)
Document how a VSCode user can configure their editor to auto-format
Clojure(Script) files that respect all the formatter (zprint) settings specified
in status-mobile/.zprintrc.

The result should be that on every file save, the file should be identically
formatted as if you used make lint-fix, at least the part about zprint. If
lint-fix does other things now or in the future that are outside the scope of
zprint, those won't be covered by the VSCode extension.

Migrate away from rf/defn and rf/merge (first step) (#17451)
This commit shows how to move away from rf/defn
f12c7401d1/src/utils/re_frame.clj (L1-L90)
& rf/merge
f12c7401d1/src/utils/re_frame.cljs (L39-L85)
and why we should do it.

## Problems

Before jumping to solutions, let's understand the problems first, in no order of
importance.

### Problem 1: Cyclic dependencies

If you ever tried to move event handlers or the functions used inside them to
different files in status-mobile, you probably stumbled in cyclic dependency
errors.

When an event is registered in re-frame, it is globally available for any other
place to dispatch. The dispatch mechanism relies on globally unique keywords,
the so called event IDs, e.g. :chat/mute-successfully. This means that event
namespaces don't need to require other event namespaces, just like you don't
need to require subscription namespaces in views.

rf/merge increases the likelihood of cyclic dependencies because they force
event namespaces to require each other. Although not as common, this happened a
few times with devs in the team and it can be a big hassle to fix if you are
unlucky. It is a problem we should not have in the first place (at least not as
easily).

### Problem 2: We are not linting thousands of lines of code

The linter (clj-kondo) is incapable of understanding the rf/defn macro. In
theory, we could teach clj-kondo what the macro produces. I tried this, but gave
up after a few tries.

This is a big deal, clj-kondo can catch many issues and will continue to catch
more as it continue to evolve. It's hard to precisely count how many lines are
affected, but `find src/ -type f -name 'events.cljs' -exec wc -l {} +` gives us
more than 4k LOC.

### Problem 3: Blocking RN's UI thread for too long

Re-frame has a routing mechanism to manage events. When an event is dispatched,
it is enqueued and scheduled to run some time later (very soon). This process is
asynchronous and is optimized in such a way as to balance responsiveness vs the
time to empty the queue.

>[...] when processing events, one after the other, do ALL the currently queued
>events. Don't stop. Don't yield to the browser. Hog that CPU.
>
>[...] but if any new events are dispatched during this cycle of processing,
>don't do them immediately. Leave them queued.
>
>-- https://github.com/day8/re-frame/blob/master/src/re_frame/router.cljc#L8-L60

Decisions were made (way back in 2017) to reduce the number of registered
re-frame events and, more importantly, to coalesce events into bigger ones with
the rf/merge pattern. I tried to find evidence of real problems that were trying
to be solved, but my understanding is that decisions were largely based on
personal architectural preferences.

Fast-forward to 2023, and we are in a situation where we have many heavy events
that process a LOT of stuff in one go using rf/merge, thus blocking the UI
thread longer than we should. See, for example,
[status-im2.contexts.profile.login.events/login-existing-profile](3082605d1e/src/status_im2/contexts/profile/login/events.cljs (L69)),
[status-im2.contexts.profile.login.events/get-chats-callback](3082605d1e/src/status_im2/contexts/profile/login/events.cljs (L98)),
and many others.

The following excerpt was generally used to justify the idea that coalescing
events would make the app perform better.

> We will reduce the the amount of subscription re-computations, as for each
> distinct action, :db effect will be produced and swapped into app-db only once
>

This is in fact incorrect. Re-frame, ever since 2015 (so before the original
discussions in 2017) uses a concept of batching to process events, which means
subscriptions won't re-run after every dispatched event, and thus components
won't re-render either. Re-frame is smarter than that.

> groups of events queued up will be handled in a batch, one after the other,
> without yielding to the browser (previously re-frame yielded to the browser
> before every single event).
>
> -- 39adca9367/docs/releases/2015.md (050--2015-11-5)

Here's a practical example you can try in a shadow-cljs :mobile REPL to see the
batching behavior in practice.

```clojure
;; A dummy event that toggles between DEBUG and INFO levels.
(re-frame/reg-event-fx :dummy-event
  (fn [{:keys [db]}]
    {:db (update-in db
                    [:profile/profile :log-level]
                    (fn [level]
                      (if (= "DEBUG" level)
                        "INFO"
                        "DEBUG")))}))

(def timer
  (js/setInterval #(re-frame/dispatch [:dummy-event])
                  50))

;; 1. In component status-im.ui.screens.advanced-settings.views/advanced-settings,
;; add a print call to see when it's re-rendered by Reagent because the
;; subscription :log-level/current-log-level will be affected by our dummy event.
;;
;; 2. Also add a print call to the subscription :log-level/current-log-level to
;; see that the subscription does NOT re-run on every dispatch.

;; Remember to eval this expression to cancel the timer.
(js/clearInterval timer)
```

If you run the above timer with 50ms interval, you'll see a fair amount of
batching happening. You can infer that's the case because you'll see way less
than 20 print statements per second (so way less than 20 recomputations of the
subscription, which is the max theoretical limit).

When the interval is reduced even more, to say 10ms (to simulate lots of
dispatches in a row), sometimes you don't see a single recomputation in a 5s
window because re-frame is too busy processing events.

This shows just how critical it is to have event handlers finishing as soon as
possible to relinquish control back to the UI thread, otherwise responsiveness
is affected. It also shows that too many dispatches in a row can be bad, just as
big event handlers would block the batch for too long. You see here that
dispatching events in succession does NOT cause needless re-computations.

Of course there's an overhead of using re-frame.core/dispatch instead of calling
a Clojure function, but the trade-off is clearly documented: the more we
process in a single event, the less responsive the app may be because re-frame
won't be able to relinquish control back to the UI thread. The total time to
process the batch increases, but re-frame can't stop in the middle compared to
when different dispatches are used.

Thus, I believe this rf/merge pattern is harmful as a default practice in an
environment such as ours, where it's desirable end-users feel a snappy RN app. I
actually firmly believe we can improve the app's responsiveness by not
coalescing events by default. We're also preventing status-mobile from taking
the most advantage from future improvements in re-frame's scheduler. I can
totally see us experimenting with other algorithms in the scheduler to best fit
our needs. We should not blindly reduce the number of events as stated here
https://github.com/status-im/status-mobile/pull/2634#discussion_r155243127.

Solution: only coalesce events into one pile when it's strictly desirable to
atomically update the app db to avoid inconsistencies, otherwise, let the
re-frame scheduler do its job by using fx, not rf/merge. When needed, embrace
*eventual app db consistency* as a way to achieve lower UI latency, i.e. write
fast and short events, intentionally use :dispatch-later or other timing effects
to bend the re-frame's scheduler to your will.

There's another argument in favor of using something like rf/merge which I would
like to deconstruct. rf/merge gives us a way to reuse computations from
different events, which is nice. The thing here is that we don't need rf/merge
or re-frame to reuse functions across namespaces. rf/merge complects re-frame
with the need to reuse transformations.

Instead, the solution is as trivial as it gets, reuse app db "transformers"
across events by extracting the logic to data store namespaces
(src/status_im/data_store). This solution has the added benefit of not causing
cyclic dependency errors.

### Problem 4: Clojure's language server doesn't understand code under rf/defn

Nowadays, many (if not most) Clojure devs rely on the Clojure Language Server
https://github.com/clojure-lsp/clojure-lsp to be more effective. It is an
invaluable tool, but it doesn't work well with the macro rf/defn, and it's a
constant source of frustration when working in event namespaces. Renaming
symbols inside the macro don't work, finding references, jumping to local
bindings, etc.

Solution: don't use rf/defn, instead use re-frame's reg-event-fx function and
clojure-lsp will understand all the code inside event handlers.

### Problem 5: Unit tests for events need to "test the world"

Re-frame's author strongly recommends testing events that contain non-trivial
data transformations, and we do have many in status-mobile (note: let's not
confuse with integration tests in status_im/integration_test.cljs). That, and
non-trivial layer-3 subscriptions should be covered too. The reasoning is that
if we have a well developed and tested state layer, many UI bugs can be
prevented as the software evolves, since the UI is partially or greatly derived
from the global state. See re-frame: What to Test?
39adca9367/docs/Testing.md (what-to-test).
See PR Introduce subscription tests
https://github.com/status-im/status-mobile/pull/14472, where I share more
details about re-frame's testing practices.

When we use rf/merge, we make unit testing events a perennial source of
frustration because too many responsibilities are aggregated in a single event.
Unfortunately, we don't have many devs in the team that attempted to write unit
tests for events to confirm my claim, but no worries, let's dive into a real
example.

In a unit test for an event, we want to test that, given a cofx and args, the
event handler returns the expected map of effects with the correct values
(usually db transformations).

Let's assume we need to test the following event. The code is still using the
combo rf/defn & rf/merge.

```clojure
(rf/defn accept-notification-success
  {:events [:activity-center.notifications/accept-success]}
  [{:keys [db] :as cofx} notification-id {:keys [chats]}]
  (when-let [notification (get-notification db notification-id)]
    (rf/merge cofx
              (chat.events/ensure-chats (map data-store.chats/<-rpc chats))
              (notifications-reconcile [(assoc notification :read true :accepted true)]))))
```

As you can see, we're "rf/merging" two other functions, namely ensure-chats and
notifications-reconcile. In fact, ensure-chats is not registered in re-frame,
but it's 99% defined as if it's one because it needs to be "mergeable" according
to the rules of rf/merge. Both of these "events" are quite complicated under the
hood and should be unit tested on their own.

Now here goes the unit test. Don't worry about the details, except for the expected output.

```clojure
(deftest accept-notification-success-test
  (testing "marks notification as accepted and read, then reconciles"
    (let [notif-1          {:id "0x1" :type types/private-group-chat}
          notif-2          {:id "0x2" :type types/private-group-chat}
          notif-2-accepted (assoc notif-2 :accepted true :read true)
          cofx             {:db {:activity-center {:filter        {:type types/no-type :status :all}
                                                   :notifications [notif-2 notif-1]}}}

          expected {:db         {:activity-center {:filter        {:type 0 :status :all}
                                                   :notifications [notif-2-accepted notif-1]}
                                 :chats           {}
                                 :chats-home-list nil}
                    ;; *** HERE ***
                    :dispatch-n [[:activity-center.notifications/fetch-unread-count]
                                 [:activity-center.notifications/fetch-pending-contact-requests]]}
          actual   (events/accept-notification-success cofx (:id notif-2) nil)]
      (is (= expected actual)))))
```

Notice the map has a :dispatch-n effect and other stuff inside of it that are
not the responsibility of the event under test to care about. This happens
because rf/merge forces the event handler to compute/call everything in one go.
And things get MUCH worse when you want to test an event A that uses rf/merge,
but A calls other events B and C that also use rf/merge (e.g. event
:profile.login/get-chats-callback). At that point you flip the table in horror
😱, but testing events and maintaining them should be trivial.

Solution: Use re-frame's `fx` effect.

Here's the improved implementation and its accompanying test.

```clojure
(defn accept-notification-success
  [{:keys [db]} [notification-id {:keys [chats]}]]
  (when-let [notification (get-notification db notification-id)]
    (let [new-notifications [(assoc notification :read true :accepted true)]]
      {:fx [[:dispatch [:chat/ensure-chats (map data-store.chats/<-rpc chats)]]
            [:dispatch [:activity-center.notifications/reconcile new-notifications]]]})))

(re-frame/reg-event-fx :activity-center.notifications/accept-success accept-notification-success)

(deftest accept-notification-success-test
  (testing "marks notification as accepted and read, then reconciles"
    (let [notif-1          {:id "0x1" :type types/private-group-chat}
          notif-2          {:id "0x2" :type types/private-group-chat}
          notif-2-accepted (assoc notif-2 :accepted true :read true)
          cofx             {:db {:activity-center {:filter        {:type types/no-type :status :all}
                                                   :notifications [notif-2 notif-1]}}}

          ;; *** HERE ***
          expected {:fx [[:dispatch [:chat/ensure-chats []]]
                         [:dispatch [:activity-center.notifications/reconcile [notif-2-accepted]]]]}
          actual   (events/accept-notification-success cofx [(:id notif-2) nil])]
      (is (= expected actual)))))
```

Notice how the test expectation is NOT verifying what other events do (it's
actually "impossible" now). Using fx completely decouples events and makes
testing them a joy again.

### Problem 6: Unordered effects

status-mobile still uses the legacy way to describe the effects map, which has
the problem that their order is unpredictable.

> Prior to v1.1.0, the answer is: no guarantees were provided about ordering.
> Actual order is an implementation detail upon which you should not rely.
>
> -- 39adca9367/docs/Effects.md (order-of-effects)

> In fact, with v1.1.0 best practice changed to event handlers should only
> return two effects :db and :fx, in which case :db was always done first and
> then :fx, and within :fx the ordering is sequential. This new approach is more
> about making it easier to compose event handlers from many smaller functions,
> but more specificity around ordering was a consequence.
>
> -- 39adca9367/docs/Effects.md (order-of-effects)

### Problem 7: Usage of deprecated effect dispatch-n

We have 35 usages, the majority in new code using dispatch-n, which has been
officially deprecated in favor of multiple dispatch tuples in fx. See
39adca9367/docs/api-builtin-effects.md (L114)

### Problem 8: Complexity 🧙‍♂️

Have you ever tried to understand and/or explain how rf/merge and rf/defn work?
They have their fare share of complexity and have tripped up many contributors.

This is not ideal if we want to create a project where contributors can learn
re-frame as quickly as possible. Re-frame is already complicated enough to grasp
for many, the added abstractions should be valuable enough to justify.

Interestingly, rf/merge is a stateful function, and although this is not a
problem in practice, it is partially violating re-frame's spirit of only using
pure functions inside event handlers.

### Problem 9: Using a wrapping macro rf/defn instead of global interceptors

When rf/defn was created inside status-mobile, re-frame didn't have global
interceptors yet (which were introduced 3+ years ago). We no longer have this
limitation after we upgraded our old re-frame version in PR
https://github.com/status-im/status-mobile/pull/15997.

Global interceptors are a simple and functional abstraction to specify functions
that should run on every event, for example, for debugging during development,
logging, etc. This PR already shows this is possible by removing the wrapping
function utils.re-frame/register-handler-fx without causing any breakage.

## Conclusion

By embracing re-frame's best practices for describing effects
39adca9367/docs/FAQs/BestPractice.md (use-the-fx-effect),
we can solve long standing issues that affect every contributor at different
levels and bring the following benefits:

- Simplify the codebase.
- Bring back the DX we all deserve, i.e. Clojure Language Server and clj-kondo
  fully working in event namespaces.
- Greatly facilitate the testability of events.
- Give devs more flexibility to make the app more responsive, because the new
  default would not coalesce events, which in turn, would block the UI thread
  for shorter periods of time. At least that's the theory, but exceptions will
  be found.

The actions to achieve those benefits are:

- Don't use the macro approach, replace rf/defn with
  re-frame.core/reg-event-fx.
- Don't use rf/merge, simply use re-frame's built-in effect :fx.
- Don't call event handlers as normal functions, just as we don't directly call
  subscription handlers. Use re-frame's built-in effect :fx.

## How do we refactor the remainder of the code?

Some numbers first:

- There are 228 events defined with rf/defn in src/status-im2/.
- There are 34 usages of rf/merge in src/status_im2/.

Upgrade shadow-cljs and ClojureScript (#15417)
This commit upgrades Shadow CLJS from 2.11.16 (released on Feb/21) to latest
2.25.0 (Jul/23), so ~1.5 years worth of upgrades. By upgrading shadow we
can finally use the latest major Clojure version 1.11.x.

Why upgrade shadow?

- Shadow CLJS controls the ClojureScript version we can use. In order to use the
  latest major Clojure version we must upgrade Shadow CLJS.

- Shadow CLJS releases new versions very frequently, and if you take a look at
  its changelog https://github.com/thheller/shadow-cljs/blob/master/CHANGELOG.md, you'll see
  it had tons and tons of bug fixes over the years. I hope some of them help
  improve the DX for certain contributors who recently reported issues with
  it.

- Clojure 1.11 brings new features, bug fixes and even performance improvements
  (although I think the performance mostly impacts Clojure on the JVM). See the
  changelog https://github.com/clojure/clojure/blob/master/changes.md#changes-to-clojure-in-version-1110

Things that can be beneficial to us, or are interesting nonetheless:

- New :as-alias to be used in require, which is like :as but does not require
  the namespace to load. This means namespaced keywords using :as-alias can't
  cause circular dependency errors. This feature would very useful if we used
  namespaced keywords, but we don't, so...
  https://github.com/clojure/clojure/blob/master/changes.md#22-as-alias-in-require
- New macros run-test and run-test-var to run single test with fixtures and
  report.
- New iteration function, useful for processing paginated data.
  https://www.abhinavomprakash.com/posts/clojure-iteration/
- New update-keys function: applies a function to every key in a map.
- New update-vals function: applies a function to every value in a map.

Examples for update-vals and update-keys. They should perform better than the
common reduce-kv approach since they use a transient data structure.

    (let [m {:a 1 :b 2}]
      (update-vals m inc)) ; => {:a 2, :b 3}
    
    (let [m {:a 1 :b 2}]
      (update-keys m name)) ; => {"a" 1, "b" 2}

Why change namespaces within __tests__ directories?

Any namespace with the word --tests-- throws an error, like the one below. I
didn't bother investigating why, so I changed the guidelines to reflect the new
convention. It's probably related to the double dashes in the name.

    Namespace quo2.components.dividers.--tests--.divider-label-component-spec has a
    segment starting with an invalid JavaScript identifier at line 1

Make json-rpc/call effect more in line with re-frame standards (#15936)
Changes effect :json/rpc-call to accept on-success and on-error parameters
either as functions OR as re-frame event vectors. The changes are 100% backwards
compatible.

## Why?

Re-frame is very explicit in its documentation and its architecture, saying that
event handlers should be pure. Calling re-frame.core/dispatch in event handlers
makes them sort of stateful.

> So, you can "get away with it". But it ain't pure.
>
> -- https://day8.github.io/re-frame/EffectfulHandlers/#90-solution

In status-mobile, arguably one of our most important effects (not to be confused
with event handlers) is :json-rpc/call, but at the moment, the on-success and
on-error values are expected to be stateful functions (e.g. usually used for
logging and dispatching subsequent events).

This creates two important problems:

1. The value returned by event handlers is more opaque and cannot be easily
   inspected (for example using tap>, log/debug or just println). If we try to
   inspect or log them, on-success and on-error will be printed as
   #object[Function].
2. Testing event handlers using :json-rpc/call becomes an exercise of
   frustration, because we can't simply compare the results of the event handler
   with a good expected value, which is one of the big selling points of testing
   pure functions.

### The testability of event handlers

> For any re-frame app, there's three things to test:
>
> - Event Handlers - most of your testing focus will be here because this is
>   where most of the logic lives
> - Subscription Handlers - often not a lot to test here. Only Layer 3
>   subscriptions need testing.
> - View functions - I don't tend to write tests for views.
>
> -- https://day8.github.io/re-frame/Testing/#what-to-test

So re-frame is saying event handlers should be pure, and that event handlers
should be tested.

In order to achieve the divine simplicity of testing event handlers as pure
functions, we need to make :json-rpc/call also accept on-success and
on-error as event vectors.

Good news is that there is a known pattern to solve this problem, e.g. used by
the library https://github.com/Day8/re-frame-http-fx.

The pattern is simple once we see it: behind the scenes, :json-rpc/call conj'es
the results of the RPC call into the event vectors on-success and on-error, and
:json-rpc/call dispatches the events itself. This eliminates the need for the
stateful dispatch call in event handlers.
