.NET 6 failing at Decompress large gzip text

Asked 2022-Feb-01 at 10:43

I have to decompress some gzip text in .NET 6 app, however, on a string that is 20,627 characters long, it only decompresses about 1/3 of it. The code I am using code works for this string in .NET 5 or .NETCore 3.1 As well as smaller compressed strings.

Missing bounds checking elimination in String constructor?

Asked 2022-Jan-30 at 21:18

Looking into UTF8 decoding performance, I noticed the performance of protobuf's UnsafeProcessor::decodeUtf8 is better than String(byte[] bytes, int offset, int length, Charset charset) for the following non ascii string: "Quizdeltagerne spiste jordbær med flØde, mens cirkusklovnen".

I tried to figure out why, so I copied the relevant code in String and replaced the array accesses with unsafe array accesses, same as UnsafeProcessor::decodeUtf8. Here are the JMH benchmark results:

Encrypt data in Javascript, Decrypt data in C# using private/public keys

I want to encrypt data in a web browser that is send to my C# backend and decrypted there.

That fails because I am unable to decrypt the data generated on the frontend in the backend.

Problem Updating to .Net 6 - Encrypting String

Asked 2021-Dec-20 at 23:09

I'm using a string Encryption/Decryption class similar to the one provided here as a solution.

This worked well for me in .Net 5.
Now I wanted to update my project to .Net 6.

When using .Net 6, the decrypted string does get cut off a certain point depending on the length of the input string.

▶️ To make it easy to debug/reproduce my issue, I created a public repro Repository here.

The encryption code is on purpose in a Standard 2.0 Project.
Referencing this project are both a .Net 6 as well as a .Net 5 Console project.

Both are calling the encryption methods with the exact same input of "12345678901234567890" with the path phrase of "nzv86ri4H2qYHqc&m6rL".

.Net 5 output: "12345678901234567890"
.Net 6 output: "1234567890123456"

The difference in length is 4.

I also looked at the breaking changes for .Net 6, but could not find something which guided me to a solution.

I'm glad for any suggestions regarding my issue, thanks!

The reason is this breaking change:

DeflateStream, GZipStream, and CryptoStream diverged from typical Stream.Read and Stream.ReadAsync behavior in two ways:

They didn't complete the read operation until either the buffer passed to the read operation was completely filled or the end of the stream was reached.

And the new behaviour is:

Starting in .NET 6, when Stream.Read or Stream.ReadAsync is called on one of the affected stream types with a buffer of length N, the operation completes when:

At least one byte has been read from the stream, or The underlying stream they wrap returns 0 from a call to its read, indicating no more data is available.

In your case you are affected because of this code in Decrypt method:

Here is a sample code to output what you need. I use the formula below to calculate pct change. percentage_change = 100*(new-old)/old

If old is 0 it is changed to 1 to avoid division by zero error.

Looks like you have mixed up 2 concepts: replication and sharding. When using replication you need to use connects_to database: { writing: :tp, reading: :tp } where writing: is the master and reading: is the read replica. If you don't have a replica than you only have to specify writing:

Looking at your code you want sharding. In this case you should use connects_to shards: { }

ANSWER

Answered 2021-Sep-24 at 00:15

So, looking at the documentation for str.splitlines, we see that the line delimiters for this method are a superset of "universal newlines":

This method splits on the following line boundaries. In particular, the boundaries are a superset of universal newlines.

Representation Description \n Line Feed \r Carriage Return \r\n Carriage Return + Line Feed \v or \x0b Line Tabulation \f or \x0c Form Feed \x1c File Separator \x1d Group Separator \x1e Record Separator \x85 Next Line (C1 Control Code) \u2028 Line Separator \u2029 Paragraph Separator

A a line for a text-file will by default use the universal-newlines approach to interpret delimiters, from the docs:

When reading input from the stream, if newline is None, universal newlines mode is enabled. Lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n' before being returned to the caller. If newline is '', universal newlines mode is enabled, but line endings are returned to the caller untranslated. If newline has any of the other legal values, input lines are only terminated by the given string, and the line ending is returned to the caller untranslated.

Install utf8

You can download it from GitHub.
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.

Support

Using the php-utf8 library is quite easy. Just include the php-utf8.php and any additional functions that you may need from the functions folder. Make sure that you are confident about using the library by reading [Character Sets / Character Encoding Issues][2] and [Handling UTF-8 with PHP][3]. Use these functions only if you really need them & you understand why you need to use them. In particular, do not blindly replace all use of PHP’s string functions which functions found here. Most of the time you will not need to, and you will be introducing a significant performance overhead to your application. Most of the functions here are not operating defensively, mainly for performance reasons. For example there is no extensive parameter checking and it is assumed that they are fed with well formed UTF-8. This is particularly relevant when is comes to catching badly formed UTF-8. You should screen input on the outer perimeter with help from functions in the utils/validation.php and utils/bad.php files. Throughout the library all ASCII characters (control characters included) are treated as valid throughout the library. Make sure you take the appropriate measures before outputting into XML since it can become ill-formed with some control characters. [more info][5].
