gem install error: incompatible function pointer types passing

sugiarto — Wed, 06 Nov 2024 00:17:58 +0000

Few days ago, I bought second macbook pro m2, and need to setup rails projects on my mac.

One type of error that raised very often was:

error: incompatible function pointer types passing 'VALUE (VALUE)'

And the fixed always by adding

--with-cflags=-Wno-error=incompatible-function-pointer-types

Sample

gem install msgpack -v '1.4.2' -- --with-cflags=-Wno-error=incompatible-function-pointer-types

I put here, so this will remind me in case I find similar issue.

Override java version on flutter

sugiarto — Sat, 02 Nov 2024 01:05:09 +0000

Today, I have a requirement to override the Java version on the Flutter project.

I used sdkman for switching between multiple Java versions, and in this case I used java 17.0.12. For the Flutter version, I used fvm and used flutter 3.24.0 on this project.

Here is the command to set java version:

fvm flutter config --jdkdir=/Users/sugiarto/.sdkman/candidates/java/current

Where jdkdir should point to your absolute path of the Java directory.

Generate tags using gemini AI

sugiarto — Tue, 01 Oct 2024 03:12:41 +0000

A week ago, I was working on a Flutter project to generate tags based on a post sentence.

The requirement was to generate tags separated by commas using the Gemini API.

Todo that, I used the flutter_gemini package to call the Gemini API.

Here is sample code to call the API.

// main.dart
Gemini.init(apiKey: dotenv.env['GEMINI_API_KEY']!);

final sampleText = "Thanks for the iPhone and food."
final gemini = Gemini.instance;
gemini.streamGenerateContent("For this text, return only the name of people or things (separated by commas), that you're highly confident that has a very high positive sentiment: $sampleText").listen((Candidates value){
  if (value?.content?.parts != null){
    if (value!.content!.parts!.isNotEmpty){
      String? text = value!.content!.parts![0].text;
      if (text != null){
        var parsedTags = text.split(", ");
        setState(() {
          for (String tag in parsedTags){
            // push to tags variable
            if (!tags.contains(tag)){
              tags.add(tag);
            }
          }
        });
      }
    }
  }
  print(value);
}).onError((error){
  print('streamGenerateContent exception $error');
});

The result would be a String with content iPhone, food.

rails system test, save failed screenshots

sugiarto — Tue, 24 Sep 2024 02:48:32 +0000

When setting up github actions for running system tests, it is sometimes difficult to know or debug when several tests fail to run but are running well locally.

So why don't you just save the failed screenshots so we know what the actual error was during the test?

First, we need to change the Rails config, so errors will appear in the browser just like what we get when running locally in development mode.

# config/environments/test.rb

config.consider_all_requests_local = true

To save screenshots, we can upload the screenshots to artifacts. Uploads steps only will be performed if the system test fails to run.

      - name: Run system test
        run: bundle exec rails test:system
      - name: Upload screenshots
        uses: actions/upload-artifact@v4
        if: failure()
        with:
          name: screenshots
          path: tmp/screenshots

github action services: mysql, redis and elasticsearch

sugiarto — Tue, 24 Sep 2024 02:30:57 +0000

A few days ago, I needed to setup github actions for running Rails tests that required MySQL, Redis, and Elasticsearch to be installed.

Here is a is a sample configuration to boot MySQL, Redis, and elasticsearch that can be accessed from 127.0.0.1 address.

    services:
      mysql:
        image: mysql:8.0
        ports:
          - 3306:3306
        env:
          MYSQL_DATABASE: sample_database_test
          MYSQL_ROOT_PASSWORD: root
        options: >-
          --health-cmd "mysqladmin ping"
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5
      redis:
        image: redis
        ports:
          - 6379:6379
        # Set health checks to wait until redis has started
        options: >-
          --health-cmd "redis-cli ping"
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5
      elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:8.13.0
        ports:
          - 9200:9200
        options: --health-cmd="curl http://localhost:9200/_cluster/health" -e "discovery.type=single-node" -e "xpack.security.enabled=false"

Recreate shopify webhooks

sugiarto — Tue, 10 Sep 2024 23:25:44 +0000

When developing custom Shopify apps, I usually use ngrok as a reverse proxy for webhooks integration. Since I always use a free service plan from Ngrok, then the URL address always changes. Here is the sample generated Ngrok URL when running

ngrok http 3000

Generated endpoint
https://73d3-2001-448a-3032-c93e-bc56-f800-e58d-8a98.ngrok-free.app

When we hit ctrl+c and rerun the command, we will get a different new URL.

So what I did was just change the .env file of my Rails project, go to console, and recreate Shopify webhooks.

bundle exec rails c

Shop.first.recreate_webhooks!

And here is the code for recreate_webhooks!

# app/models/shop.rb

  def recreate_webhooks!
    ShopifyAPI::Webhook.all.each do |webhook|
      webhook.destroy
    end

    ShopifyApp.configuration.webhooks.each do |item|
      webhook = ShopifyAPI::Webhook.new(item)
      if webhook.save
        puts "webhook #{item} created."
      else
        puts "webhook #{item} failed."
      end
    end
  end

So every time you need to regenerate webhooks, you can just run this method from rails console.

searchkick get total records

sugiarto — Sun, 08 Sep 2024 10:15:39 +0000

In one of my projects, I used searchkick gem and elasticsearch for implementing search feature.

Something weird happens when database records are over 10K records. The total records always show 10K, even though the actual records are 267K.

I fixed this issue by adding

body_options: { track_total_hits: true }

As an argument for the search method.

Here is an example

collections = MyModel.pagy_search(query, fields: [:name], load: false, body_options: { track_total_hits: true })
pagy, properties = pagy_searchkick(collections)

Create supabase database function

sugiarto — Sun, 08 Sep 2024 09:19:59 +0000

Two days ago, I had a requirement to create a database function that accepts a single argument, in this case a 'user_id', and returns custom data as a table.

To create this function, we need to open SQL Editor.

Here is the sample code that I used at my function:

create or replace function get_friends(user_id uuid)
 RETURNS TABLE(
    friend_id uuid,
    updated_at timestamptz,
    first_name text,
    last_name text,
    email text,
    profile_image_url text,
    location text
  )
  language plpgsql as
$$

BEGIN
  RETURN QUERY
  select
    friends.friend_id,
    friends.updated_at,
    users.first_name,
    users.last_name,
    users.email,
    users.profile_image_url,
    users.location
  from friends
  inner join users ON users.id = friends.friend_id
  where
    friends.user_id = get_friend_ids.user_id AND
    friend_status = 'approved' AND
    users.info_complete = true

  union

  select
    friends.user_id friend_id,
    friends.updated_at,
    users.first_name,
    users.last_name,
    users.email,
    users.profile_image_url,
    users.location
  from friends
  inner join users ON users.id = friends.user_id
  where
    friends.friend_id = get_friends.user_id AND
    user_status = 'approved' AND
    users.info_complete = true;
end;
$$;

As I want to function to return a custom table, so I used table as return values.

RETURNS TABLE(
    friend_id uuid,
    updated_at timestamptz,
    first_name text,
    last_name text,
    email text,
    profile_image_url text,
    location text
  )

To call this function within a SQL editor.

select * from get_friends(uuid('e7839548-40e8-4c7e-8f6c-2b5cee6bde2d'))

We used uuid() to convert from text to uuid.

Hope this helps.

searchkick resource_already_exists_exception

sugiarto — Mon, 02 Sep 2024 22:32:19 +0000

Yesterday, I worked on elasticsearch integration with help of searchkick.

I did several times adding searchkick to Rails projects but never got this error before:

`__raise_transport_error': [400] {"error":{"root_cause":[{"type":"resource_already_exists_exception","reason":"index [house_development_20240902225059955/3Jvd0sYAT46lRDc8O-CgDQ] already exists"

This error was raised when I ran

MyModel.reindex

From the error description, I can say the problem is index already exists and failed to recreate the index. So I tried to delete the index using curl,

show all indexes.

curl http://elastic:ELASTICSEARCH_PASSSWORD@127.0.0.1:9200/_aliases?pretty=true

delete index.

curl -X DELETE http://elastic:CbHBbB9PS5xYB5RdOTQP@127.0.0.1:9200/house_development_20240902225059955

After that, then I tried to call MyModel.reindex again, but the same error still happened.

Then I tried to check the elasticsearch server log and got this:

high disk watermark [90%] exceeded on [WPlL99sKQ7CnX59V0PiC-Q][cc376a2237d1][/usr/share/elasticsearch/data] free: 47.2gb[9.9%], shards will be relocated away from this node; currently relocating away shards totalling [0] bytes; the node is expected to continue to exceed the high disk watermark when these relocations are complete

After googling, I found this SO question, and just tried to change threshold_enabled that made indexing back to work.

curl -XPUT "http://elastic:ELASTICSEARCH_PASSSWORD@127.0.0.1:9200/_cluster/settings" \
 -H 'Content-Type: application/json' -d'
{
  "persistent": {
    "cluster": {
      "routing": {
        "allocation.disk.threshold_enabled": false
      }
    }
  }
}'

Hope this helps for you.
