(I plan to publish this as a blog post once a few people have looked at it and caught the obvious typos.)

I got lots of positive feedback about the FAQ section in my Rust 2020 blog post, so I'm trying that format again for another topic that's been requested a lot: How to fix common borrow-checker issues. This isn't meant to explain how or why the borrow checker works the way it does (see The Nomicon or Two Beautiful Rust Programs for that), just how to work around some of its current limitations.

Like Flask "g". Good news you can do the same with FastAPI

"g" is a threadlocal magic object that lets developer add / change / remove attributes during the request lifecycle. Learn more about this "g" here.

There is no OTB equivalent in FastAPI, but thanks to the new contextvars Python 3.7+ module, I made this simple demo.

Any comment or help to improve yhis recipe is welcome.

This recipe is a work in progress and has never been run as-is.

• timeouts are in ms
• lock timeout: in postgres, when a statement that wants a restrictive lock waits on another lock, other statements that want locks can't jump the queue. so even though the statement that is waiting might only take a very short amount of time, when it starts running, while it is waiting no other statements can begin. So we set the lock timeout pretty low and retry if we don't get it.
• statement timeout: we set a short statement timeout before statements which do lock and which we expect to take a short amount of time, just in case something about our assumptions/understanding is wrong and the statement ends up taking a long time. if this happens the statement will bail early without causing harm, and we can investigate what is wrong with

Общее

1. Представься: краткая информация о себе – имя, место работы, чем занимаешься, можно фото для тех, кто будет смотреть слайды отдельно
2. План доклада: несколько пунктов (лучше не более 5) о чём будет доклад. Это могут быть главы доклада (кстати, составление плана может помочь грамотнее структурировать доклад ещё при создании)
3. Зачем: кратко рассказать, чем то, о чем рассказываешь в докладе, может быть полезно остальным – и разработчикам, и руководителям, и клиентам (можно акцентироваться на аудитории конкретной конфы – например если там есть дизайнеры, бэкенды, то упомянуть, что они могут узнать из доклада)
4. Итоги: в конце доклада ещё раз пройтись по плану и подвести итог по каждому пункту – что узнали, чему научились
5. Контакты: как слушатель и тот кто смотрит слайды может связаться и задать вопрос
