Chromium development gclient

gclient is a command-line tool used primarily in the context of Chromium development. It is part of the depot_tools suite, which is a collection of tools maintained by the Chromium project team to aid in managing large codebases like Chromium.

Here are some key aspects of gclient:

  1. Source Code Management: gclient is used to manage the source code repositories that make up Chromium and its dependencies. It handles tasks such as cloning repositories, fetching updates, and managing dependencies.

  2. Synchronization: It helps synchronize the source code across different repositories and ensures that all dependencies are up to date. This is crucial in a project like Chromium, which consists of multiple interconnected modules and libraries.

  3. Usage with fetch: The most common use of gclient is in conjunction with the fetch command. For example, fetch chromium will clone the Chromium repository and all necessary dependencies into a specified directory (src by default).

  4. Configuration Management: gclient also manages the configuration files (.gclient and .gclient_entries) that specify which repositories are part of the project and their respective URLs and branches.

  5. Dependency Management: In addition to fetching source code, gclient can also manage third-party dependencies and ensure they are correctly integrated into the build process.

Overall, gclient simplifies the process of setting up and maintaining a complex development environment like Chromium by automating many of the tasks related to managing multiple repositories and their dependencies.

Using the MinIO API via curl

Using the MinIO API via curl is straightforward, as MinIO is compatible with Amazon S3 API, so most commands follow a similar syntax. Here’s a guide on how to use curl with the MinIO API for some common operations like uploading, downloading, and managing objects. Prerequisites Access Key and Secret Key : Obtain your MinIO Access Key and Secret Key. MinIO Endpoint : Know your MinIO server endpoint, e.g., http://localhost:9000 . Bucket : You may need an existing bucket name, or create a new one using the commands below. Authentication Header For requests to work with MinIO, you need to include authentication in the headers. MinIO uses AWS Signature Version 4 for signing requests. Common Examples 1. List Buckets To list all buckets in your MinIO account, use: curl -X GET \ - -url "http://localhost:9000/" \ - H "Authorization: AWS <AccessKey>:<Signature>" 2. Create a Bucket To create a new bucket, use: curl -X PUT \ - -url "htt...

max_active_runs of Airflow

In Apache Airflow, if you want to ensure that a new run of a DAG doesn’t start before the previous one has completed, you can use the max_active_runs parameter in the DAG definition. Setting this parameter to 1 ensures that only one instance of the DAG is running at any given time. Setting max_active_runs for a DAG Here’s an example of how to set up a DAG with max_active_runs=1 : from airflow import DAG from airflow.operators.dummy_operator import DummyOperator from datetime import datetime # Define the DAG with DAG( 'my_dag' , description= 'A sample DAG' , schedule_interval= '@daily' , # Set your schedule start_date=datetime( 2023 , 1 , 1 ), catchup= False , max_active_runs= 1 # This prevents new runs before the previous run completes ) as dag: # Define tasks start = DummyOperator(task_id= 'start' ) end = DummyOperator(task_id= 'end' ) # Define task dependencies ...

how to delete all issues on project in sentry, 센트리 이슈 삭제하기

As of now, Sentry doesn't have a direct feature to delete all issues in bulk through the web interface. However, there are a few methods you can use to archive, resolve, or delete issues programmatically or by adjusting project settings: 1. Bulk Archive Issues from the Web Interface Though there is no mass delete option, you can bulk archive or resolve issues, which essentially hides them from active issue lists. Steps: Go to your Sentry project. In the issue list view, select the issues you want to archive or resolve. Use the "Select All" checkbox to select multiple issues. Choose "Resolve" or "Archive" from the bulk action dropdown. However, this doesn't delete the issues permanently; they will be archived or marked as resolved. 2. Adjust Retention Policy (Data Retention Settings) If you're looking to remove older issues, you can adjust the retention policy at the organization level. Sentry allows you to configure how long issue...

difference between truncate and truncate_preserve in hbase

In HBase, both truncate and truncate_preserve commands are used to delete all the data in a table, but they behave differently in terms of how they handle the table’s schema and regions. 1. truncate Purpose : Deletes all data and regions in a table and then recreates it with the same schema. What It Does : When you run truncate , it: Disables the table. Deletes all data and metadata (including region splits) in the table. Drops all regions and recreates the table as a single region with the original schema. Re-enables the table. Effect on Regions : After truncate , all region splits are lost, so the table will start with only one region. This is useful for development or quick data purging but is inefficient for large tables that rely on pre-split regions for load balancing. Command Syntax : truncate 'table_name' 2. truncate_preserve Purpose : Deletes all data in a table but preserves the table’s regions and schema. What It Does : When you use truncate_...
