kandi X-RAY | cached Summary

cached is a Rust library typically used in Server, Caching applications. cached has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Caching structures and simplified function memoization. cached provides implementations of several caching structures as well as a handy macros for defining memoized functions. Memoized functions defined using #[cached]/#[once]/#[io_cached]/cached! macros are thread-safe with the backing function-cache wrapped in a mutex/rwlock, or externally synchronized in the case of #[io_cached]. By default, the function-cache is not locked for the duration of the function's execution, so initial (on an empty cache) concurrent calls of long-running functions with the same arguments will each execute fully and each overwrite the memoized value as they complete. This mirrors the behavior of Python's functools.lru_cache. To synchronize the execution and caching of un-cached arguments, specify #[cached(sync_writes = true)] / #[once(sync_writes = true)] (not supported by #[io_cached]. The procedural macros (#[cached], #[once], #[io_cached]) offer more features, including async support. See the proc_macro and macros modules for more samples, and the examples directory for runnable snippets.`. Any custom cache that implements cached::Cached/cached::CachedAsync can be used with the #[cached]/#[once]/cached! macros in place of the built-ins. Any custom cache that implements cached::IOCached/cached::IOCachedAsync can be used with the #[io_cached] macro.

QUESTION

Azure Container Registry - price per Gb or Cached Images TTL

Asked 2021-Jun-15 at 02:41

i am new on Azure. I will use Container Registry, but Azure has different pricing model. Different as GCP and AWS. Pay per day for 10 Gb. https://azure.microsoft.com/en-us/pricing/details/container-registry/

But i have only one image for 500Mb. 5$ per Month is not a big money, but i would like to pay for my 500Mb but not for 10Gb which i don't use.

Is there a workaround?

If I pull the image from other repo. Will be image bei Azure cached? If yes, then what is TTL for my image? I cannot find the info.

https://docs.microsoft.com/en-us/azure/container-instances/container-instances-faq#how-can-i-speed-up-the-deployment-of-my-container

Thanks for advice.

Answered 2021-Jun-15 at 02:41

There is no workaround to reduce the payment. For example, the Basic SKU include at least 10 GB storage, you can't pay less than $0.167 each day for the storage, even if you only use 500MB. Just like you use a part of something, but you can't only buy the part, you need to buy the whole thing.

If I pull the image from other repo. Will be image bei Azure cached? If yes, then what is TTL for my image?

The cache images mean Azure already pulled the images and don't need to pull again. The time to pull your custom image depends on two things. One is if the base image or your custom image in the list of the cached images. Another one is that how many layers your custom image have except the cached image. So Azure suggest you switch to use the cached image as the image or the base image and try to create less layers.

How to get wtforms to take json and insert data into the form object?

Asked 2021-Jun-15 at 00:52

The situation:

I am using React in the front-end and a Flask api server. I am wanting to send the data from React to the api and once I have done this I would like to use WTForms to run validations on the data before handling it. The question may seem similar to CSRF Protection with Flask/WTForms and React , but this does not answer the question, please take a look through I have put a lot of effort in writing a good question.

What I have

Currently the data is being sent successfully as a json object, where the keys match the names within the wtform structure, the aim is to get wtforms to take that json data and insert it into the object and and handle from there as normal

I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too. I believe it's something with Redis, as I'm using it to store the system cache. When I go to access my endpoint in postman it returns the following error:

Your problem is that you have set SESSION_CONNECTION=session, but your SESSION_DRIVER=default, so you have to use SESSION_DRIVER=database in your .env. See the config/session.php:

QUESTION

“500 Internal Server Error” with job artifacts on minio

Asked 2021-Jun-14 at 18:30

I'm running gitlab-ce on-prem with min.io as a local S3 service. CI/CD caching is working, and basic connectivity with the S3-compatible minio is good. (Versions: gitlab-ce:13.9.2-ce.0, gitlab-runner:v13.9.0, and minio/minio:latest currently c253244b6fb0.)

Is there additional configuration to differentiate between job-artifacts and pipeline-artifacts and storing them in on-prem S3-compatible object storage?

In my test repo, the "build" stage builds a sparse R package. When I was using local in-gitlab job artifacts, it succeeds and moves on to the "test" and "deploy" stages, no problems. (And that works with S3-stored cache, though that configuration is solely within gitlab-runner.) Now that I've configured minio as a local S3-compatible object storage for artifacts, though, it fails.

The answer is to bypass the empty-string test; the underlying protocol does not support region-less configuration, nor is there a configuration option to support it.

The trick is able to work because the use of 'endpoint' causes the 'region' to be ignored. With that, setting the region to something and forcing the endpoint allows it to work:

After thinking a little bit, I think I know what your problem is, you are using function ($keywords), but you should be using function () use ($keywords) because, in the source code, you see that it is doing $value = $callback(), but your function is awaiting $keywords, if you want to share a value, you have to use use ($keywords) again, like your second function in the where.

So, it should be:

Use git filter-branch for what it's good for, use git filter-repo for what it's better for. I doubt it's possible to make filter-repo do what you're after at all, or at any rate not nearly so well.

I recommend simply ignoring most of the criticisms leveled at git filter-branch, particularly the ones in the filter-repo readme, as regrettably overstated. Put export FILTER_BRANCH_SQUELCH_WARNING=1 in ~/.bashrc and be done with it.

You've used -Xms to force the JVM to get ~30GB at JVM startup.

It has tried, and failed. It only obtained 8GB. It needs another 22-ish GB but cannot get it. That is what the error message is telling you. This is consistent with a dump that says the heap is only 8GB.

You're asking for more than the OS will provide. You'll need to figure out what's going on in the OS in general.

Your application code is probably not involved. The JVM is still initializing its heap in accordance with your command-line options.
