kandi X-RAY | PauselessHashMap Summary
pauselesshashmap: a java.util.hashmap compatible map implementation that performs background resizing for inserts, avoiding the common "resize/rehash" outlier experienced by normal hashmap. get() and put() operations are "pauseless" in the sense that they do not block during resizing of the map. other operations, like remove(), putall(), clear(), and the derivation of keysets and such will block for pending resize operations. like hashmap, pauselesshashmap provides no synchronization or thread-safe behaviors on it's own, and must be externally synchronized if used by multiple threads. the background resizing mechanism relies on the calling program enforcing serialized access to all methods, and behavior is undefined if concurrent access (for modification or otherwise) is allowed. and like hashmap, pauselesshashmap is an implementation of map. all optional operations (adding and removing) are supported. keys and values can be any objects. here is some more background and commentary i included in my posting on the mechanical sympathy group on the subject: some background: as those of you who have read my various rants may have noticed, i spend a lot of my time thinking about the behavior of latency/response-time/reaction-time. in addition to trying to understand and teach about the behavior better (with monitoring and measurement tools like hdrhistogram, latencyutils, and jhiccup), i actually work on things that try

QUESTION
I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs
...ANSWER
Answered 2022-Mar-16 at 07:01First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".
January 11, 2022 Final brownout.
This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.
Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.
As noted by Jörg W Mittag:
For GitHub Actions:There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".
Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.
The permanent shutdown is not until March 15th.
As in actions/checkout issue 14, you can add as a first step:

In the current stable Rust, is there a way to write a function equivalent to BTreeMap::pop_last?

...ANSWER
Answered 2022-Mar-15 at 16:55Is there a way to work around this issue without imposing additional constraints on map key and value types?
It doesn't appear doable in safe Rust, at least not with reasonable algorithmic complexity. (See Aiden4's answer for a solution that does it by re-building the whole map.)
But if you're allowed to use unsafe, and if you're determined enough that you want to delve into it, this code could do it:
QUESTION
I've built my React Native app and tested and troubleshooted with my iOS devices for months. Now I'm trying to built and test the app on Android for the first time. The thing is, that I keep getting errors trying to run the Android-version of my app. After hours of debugging and troubleshooting, I tried to create a new RN project and see if that could run on my emulator and device. I got that part working and then I wanted to copy/paste the files of my existing app project into the new project.
I pasted my existing assets, styles, the source JS-files and the package.json file into the new project, ran npm install and then I ended up with the exact same error message as I had in the original project when I run react-native run-android.
The full error message is here:
...ANSWER
Answered 2021-Aug-21 at 13:43I've hit this same issue and have temporarily resolved it by uninstalling react-native-video (npm uninstall --save react-native-video). That's not a great answer as I need that component, but I don't have a full solution yet. I think somehow com.yqritc:android-scalablevideoview:1.0.4. is required by react-native-video but has gotten lost or removed. Other thoughts are welcome.
UPDATE: Resolved! In your build.gradle in your Android folder you need to add the repository "jcenter()" in allprojects (not in build dependencies) like this...

Apparently throwError(error) is now deprecated. The IntelliSense of VS Code suggests throwError(() => new Error('error'). new Error(...) accepts only strings. What's the correct way to replace it without breaking my HttpErrorHandlerService ?

I know that compiler is usually the last thing to blame for bugs in a code, but I do not see any other explanation for the following behaviour of the following C++ code (distilled down from an actual project):

Answered 2022-Feb-01 at 15:49The evaluation order of A = B was not specified before c++17, after c++17 B is guaranteed to be evaluated before A, see https://en.cppreference.com/w/cpp/language/eval_order rule 20.
The behaviour of valMap[val] = valMap.size(); is therefore unspecified in c++14, you should use:

QUESTION
I got a large list of JSON objects that I want to parse depending on the start of one of the keys, and just wildcard the rest. A lot of the keys are similar, like "matchme-foo" and "matchme-bar". There is a builtin wildcard, but it is only used for whole values, kinda like an else.
I might be overlooking something but I can't find a solution anywhere in the proposal:

I also faced this issue, and it seems that there is a known issue on Xcode 13 as mentioned in this document: https://developer.apple.com/documentation/Xcode-Release-Notes/xcode-13-release-notes
Swift libraries depending on Combine may fail to build for targets including armv7 and i386 architectures. (82183186, 82189214)
Workaround: Use an updated version of the library that isn’t impacted (if available) or remove armv7 and i386 support (for example, increase the deployment target of the library to iOS 11 or higher).
If your app is for iOS 11 or higher, one of the libraries should be modified to target iOS 11 or higher (e.g., my app is for iOS 12 or higher).
For example, I am using GRDB.swift, and its minimum iOS version is 10.0. There was a discussion as an issue of this repo, and I followed that comment to solve this issue as follows:
- Fork the repository
- Change Package.swift to modify the minimum iOS version like:
