kandi X-RAY | legacy Summary
Legacy is a utility for uploading Cassandra snapshots and incremental backups to S3. Light-weight, simple tool that can be run on individual nodes. It supports backing up snapshots and incremental backups, as well as tidying up incremental backups as it goes along. Make sure to get the latest version from the [Releases Section] rather than master (which should be treated as unstable just in-case). Used in production [Cassandra 2.1+] in its current state - stable enough and provides the necessary functionality to keep a clean consistent backup of a multi-node, multi-terrabyte cluster. Assuming the nodetool snapshot has --tags and the directory structure of the data/snapshots/backups directory is the same on 2.0 it should work. See the to-do’s below for a more descriptive list of features that Version 1 should / will comprise of.

QUESTION
I encountered the following error when I tried to install some new packages using npm install. It happened when I did npm install a-new-package --save and then delete package-lock.json file afterwards to refresh everything.
ANSWER
Answered 2021-Jun-15 at 18:59May be deleting node_modules folder and package-lock.json file and then reinstalling npm would resolve your issue.
So, consider the following commands to apply the above operations:
QUESTION
I am aware that floating-point numbers are tricky. But today I encountered a case that I cannot explain (and cannot reproduce using a standalone C++ code).
The code within a large project looks like this:
...ANSWER
Answered 2021-Jun-15 at 09:57Barring the undefined behavior which can be easily be fixed, you're seeing the effect of denormal numbers. They're extremely slow (see Why does changing 0.1f to 0 slow down performance by 10x?) so in modern FPUs there are usually denormals-are-zero (DAZ) and flush-to-zero (FTZ) flags to control the denormal behavior. When DAZ is set the denormals will compare equal to zero which is what you observed
Currently you'll need platform-specific code to disable it. Here's how it's done in x86:
QUESTION
This question is related to Azure MSIX Build and Package task only has Release and Debug configurations
We have a WinForms project that has an MSIX installer. Manually, we can successfully create
- An MSIXBUNDLE and deploy it to Kudu
- An MSIX and deploy it to an Azure VM through a VHDX. We have manually convert the MSIX to a VHDX first
We are now trying to automate the build and release process to create the VHDX. However, we are getting a blank screen when the VHDX is mounted using a process that we have already validated. The only thing different is the build method (i.e., MSBuild versus VS Publish).
How do we create a working VHDX in Azure CI Build Pipeline?
Below is the YAML.
...ANSWER
Answered 2021-Jun-15 at 14:26Actually, there is nothing wrong with the YAML. The problem was a delay in the virtual machine loading the VHDX. In other words, wait about 5 minutes once the VHDX is mounted before trying to run the application. I am leaving this here in case anyone else runs into this issue.
QUESTION
I have a pair of iterator, and I would like to use ranges::views::filter(some_predicate) on it (with the pipe operator). AFAIU I should first convert my pair of iterator into a view. I tried to use ranges::subrange(first, last) to do so, but I’m getting horrible error messages.
Note1: I’m using C++14 and range-v3 version 0.9.1 (the last version compatible with gcc-5.5). If the solution differs when using C++17/20 and/or when using C++20 std::ranges, I’m also interested to know what changed.
Note2: I find the documentation of range-v3 severely lacking, so I’m using cppreference.com. If you know a better documentation, I’m very interested.
EDIT:
In my real code, I’m wrapping a java-style legacy iterator (that has a next() method instead of operator++/operator*. I’m wrapping them in a C++-compatible wrapper. Then I tried to convert that wrapper into a view, and finally filter it. I reproduce a minimal example on godbolt. This use iterator_range as suggested, but it still doesn’t compile (see the second edit below).
ANSWER
Answered 2021-Apr-08 at 16:24In ranges-v3, there is iterator_range which you can use to wrap the iterators into a range object.
In C++20, you can use std::span to wrap those iterators into an range object
QUESTION
I've been tasked with porting a piece of legacy software and the client has decided they want to update Boost from 1.34 to 1.75 in the process.
Unfortunately, I'm having this issue show up when compiling:
...ANSWER
Answered 2021-Jun-09 at 10:17I think this is a conflict with third-party headers which we've seen before here:
"xtime: ambiguous symbol" error, when including
In that case reordering the includes worked out. If that doesn't work in your situation, you should work out which library is to blame (usually its the one that contaminates global namespace with (macro) definitions).
And then you can report the defect to the respective maintainers.
QUESTION
Im currently tackling the optimization of combining two arrays. The problem is the following:
- I have 2 Arrays of different sizes with Array A beeing smaller in all cases that Array B (Most of the time with different magnitude)
- Array A contains objects in with two ID's
ANSWER
Answered 2021-Jun-14 at 12:42The problem in both solutions is the need to iterate array A for every item in array B.
Instead create a Set from the 1st array (A) relevant ids, and then filter the 2nd array (b) by checking that the relevant id doesn't appear in the Set:

QUESTION
A legacy piece of software using the provider "sqloledb.1" via the OleDbConnection Class (System.Data.OleDb.dll) is still working on Windows Server 2019 with TLS1.2. Whereas on Server 2016 or 2012 R2 with TSL1.2 it is not?
Windows Server 2016 gets the following error, which is expected as it is using the sqloledb which doesn't support TLS1.2. This is well known as seen here.
...ANSWER
Answered 2021-Jun-12 at 12:21sqloledb is part of Windows, and it was recently updated to support TLS 1.2. See KB4580390.
So as of "Windows 10, version 1809, Windows Server version 1809" this should work.

I want to get a document in a stored procedure by partition key and id.
I guess readDocument is a function for point reads.
readDocument(String documentLink, RequestOptions options)
It needs a "documentLink" string as the first argument.
What is it?
...ANSWER
Answered 2021-Jun-11 at 05:11From the docs,
The format for documentLink is always "dbs/{db identifier}/colls/{coll identifier}/docs/{doc identifier}" only the values within the {} change depending on which method you wish to use to address the resource.
