I use HttpClient to get the content of the pages on the internet and was faced with weird behavior.

Some sites load perfectly, but some requests fail by timeout. The thing is that the links work perfectly in the browser. E.g. I have the following link: https://www.luisaviaroma.com/en-gb/shop/women/shoes?lvrid=_gw_i4. I can open it in the browser, but my code doesn't work:

Scrapy - ReactorAlreadyInstalledError when using TwistedScheduler

Asked 2022-Apr-01 at 14:33

I have the following Python code to start APScheduler/TwistedScheduler cronjob to start the spider.

Using one spider was not a problem and worked great. However using two spiders result into the error: twisted.internet.error.ReactorAlreadyInstalledError: reactor already installed.

I did found a related question, using CrawlerRunner as the solution. However, I'm using TwistedScheduler object, so I do not know how to get this working using multiple cron jobs (multiple add_job()).

https://docs.scrapy.org/en/latest/topics/practices.html#run-scrapy-from-a-script

There’s another Scrapy utility that provides more control over the crawling process: scrapy.crawler.CrawlerRunner. This class is a thin wrapper that encapsulates some simple helpers to run multiple crawlers, but it won’t start or interfere with existing reactors in any way.
It’s recommended you use CrawlerRunner instead of CrawlerProcess if your application is already using Twisted and you want to run Scrapy in the same reactor.

https://docs.scrapy.org/en/latest/topics/practices.html#running-multiple-spiders-in-the-same-process

By default, Scrapy runs a single spider per process when you run scrapy crawl. However, Scrapy supports running multiple spiders per process using the internal API.

SQLAlchemy queries running twice, only on a separate thread with long execution time

...

ANSWER

Answered 2022-Mar-23 at 22:07

The app.run function of Flask will run your initialization code twice when you set debug=True. This is part of the way Flask can detect code changes and dynamically restart as needed. The downside is that this is causing your thread to run twice which in turn creates a race condition on reading and executing your tasks, which indeed would only show up when the task takes long enough for the second thread to start working.

See this question/answer for more details about what is happening: Why does running the Flask dev server run itself twice?

To avoid this you could add code to avoid the second execution, but that has the limitation that the auto-reloading feature for modified code will no longer work. In general, it would probably be better to use something like Celery to handle task execution instead of building your own solution. However, as mentioned in the linked answer, you could use something like

Dask distributed has a fire_and_forget method which is an alternative to e.g. client.compute or dask.distributed.wait if you want the scheduler to hang on to the tasks even if the futures have fallen out of scope on the python process which submitted them.

Scheduling a satutus change using celery in django

Asked 2022-Mar-02 at 11:24

In my program, I have scheduled a task that is aimed at changing the status of insurance to Expiré if the due date is equal to the current date when I run the program. The script supposes to loop up throughout the Contract's table and fetches the rows that are corresponding to the condition we used in the script. However, it is changing the status of the whole table including rows that should not be affected by the imposed condition. Here is the jobs.py file that is scheduling the task of changing the status of the insurance to Expiré if the condition is true.

Calling initialize with no parameters will create and start an instance of the Scheduler with default configuration options. Initialize also takes a single lambda/action parameter for custom configuration. In this case we choose not to start the Scheduler automatically. Instead, we create a scheduler instance and start the instance explicitly after the Scheduler initialization.
