QUESTION
Good Day!
I would like ask for your help on decompressing String back to its original data.
Here's the document that was sent to me by the provider.
Data description
First part describes the threshold data.
All data are managed as Little Endian IEEE 754 single precision floating numbers. Their binary representation are (represented in hexadecimal data) :
Compressed data (zip) Threshold binary data are compressed using the ‘deflate’ algorithm. Each compression result is given here (represented in hexadecimal data) :
Thresholds: $63 00 03 05 47 24 DA 81 81 A1 C1 9E 81 61 01 98 06 00
Encoded data (base64) Threshold compressed data are encoded in ‘base64’ to be transmitted as ASCII characters. Each conversion results is given here (represented in hexadecimal data) :
Thresholds: $59 77 41 44 42 55 63 6B 32 6F 47 42 6F 63 47 65 67 57 45 42 6D 41 59 41
Here is the output frame (Manufacturer frame content) The thresholds data are then sent using their corresponding ASCII character Here is the resulting Histogram ASTM frame sent :
YwADBUck2oGBocGegWEBmAYA
As explained in above details, what I want to do is backwards.
The packets that we received is
YwADBUck2oGBocGegWEBmAYA
then from there convert it to Hex value Base64 which is the output is.
Thresholds: $59 77 41 44 42 55 63 6B 32 6F 47 42 6F 63 47 65 67 57 45 42 6D 41 59 41
This first part was already been implemented using this line of codes.
...ANSWER
Answered 2022-Mar-23 at 16:03Your input string is a base64 encoded array of bytes, representing a compressed (deflated) sequence of floating point values (float / Single).
- You can use Convert.FromBase64String() to get the compressed bytes
- Initialize a MemoryStream with this byte array. It's used as the input stream of a DeflateStream
- Initialize a new MemoryStream to receive the deflated content from the DeflateStream.CopyTo() method
- Get a series of 4 bytes from the decompressed array of bytes and reconstruct the original values (here, using BitConverter.ToSingle() and an ArraySegment(Of Byte)).
An example:

ANSWER
Answered 2022-Mar-28 at 14:18This error is harmless in the sense that it does not indicate a broken repository. It is a bug that was introduced in Git 2.35 and that should be fixed in later releases.
The worst that can happen is that git gc does not prune all objects that are referenced from reflogs.
The error is triggered by an invocation of git reflog expire --all that git gc does behind the scenes.
The trigger are empty reflog files in the .git/logs directory structure that were left behind after a branch was deleted. As a workaround you can remove these empty files. This command lets you find them and check their size:
QUESTION
I need help debugging Webpack's Compression Plugin.
SUMMARY OF PROBLEM
- Goal is to enable asset compression and reduce my app's bundle size. Using the Brotli algorithm as the default, and gzip as a fallback for unsupported browsers.
- I expected a content-encoding field within an asset's Response Headers. Instead, they're loaded without the field. I used the Chrome dev tools' network tab to confirm this. For context, see the following snippet:
- No errors show in my browser or IDE when running locally.
WHAT I TRIED
- Using different implementations for the compression plugin. See below list of approaches:
- (With Webpack Chain API)
ANSWER
Answered 2021-Sep-30 at 14:59It's not clear which server is serving up these assets. If it's Express, looking at the screenshot with the header X-Powered-By, https://github.com/expressjs/compression/issues/71 shows that Brotli support hasn't been added to Express yet.
There might be a way to just specify the header for content-encoding manually though.
QUESTION
If I run git fetch origin and then git checkout on a series of consecutive commits, I get a relatively small repo directory.
But if I run git fetch origin and then git checkout FETCH_HEAD on the same series of commits, the directory is relatively bloated. Specifically, there seem to be a bunch of large packfiles.
The behavior appears the same whether the commits are all in place at the time of the first fetch or if they are committed immediately before each fetch.
The following examples use a public repo, so you can reproduce the behavior.
Why is the directory size of example 2 so much larger?
Example 1 (small):
...ANSWER
Answered 2022-Mar-25 at 19:08Because each fetch produces its own packfile and one packfile is more efficient than multiple packfiles. A lot more efficient. How?
First, the checkouts are a red herring. They don't affect the size of the .git/ directory.
Second, in the first example only the first git fetch origin does anything. The rest will fetch nothing (unless something changed on origin).
Compression works by finding common long sequences within the data and reducing them to very short sequences. If
long block of legal mumbo jumbo appears dozens of times it could be replaced with a few bytes. But the original long string must still be stored. If there's a single packfile it must only be stored once. If there's multiple packfiles it must be stored multiple times. You are, effectively, storing the whole history of changes up to that point in each packfile.
We can see in the example below that the first packfile is 113M, the second is 161M, the third is 177M, and the final fetch is 209M. The size of the final packfile is roughly equal to the size of the single garbage compacted packfile.
Why do multiple fetches result in multiple packfiles?git fetch is very efficient. It will only fetch objects you not already have. Sending individual object files is inefficient. A smart Git server will send them as a single packfile.
When you do a single git fetch on a fresh repository, Git asks the server for every object. The remote sends it a packfile of every object.
When you do git fetch ABC and then git fetch DEFs, Git tells the server "I already have everything up to ABC, give me all the objects up to DEF", so the server makes a new packfile of everything from ABC to DEF and sends it.
Eventually your repository will do an automatic garbage collection and repack these into a single packfile.
We can reduce the examples. I'm going to use Rails to illustrate because it has clearly defined tags to fetch.

ANSWER
Answered 2022-Mar-21 at 06:34As has been commented in the comments section, the issue has been solved by moving the project folder outside the OneDrive directory.
Because it's a synchronized cloud folder, as soon as you install/add/delete/update anything, it's being updated in the OneDrive cloud so the file/folder it's being used in the background and potentially unreachable. If at this time you try to develop the project (gatsby develop or gatsby build) and the file is being used, you won't be able to run it.
I don't think it's a good practice to use a cloud folder because the amount of data synchronized (mainly because of the node_modules) it's something to care about (it's also ignored in the .gitignore for a reason) so moving it to any other folder outside the OneDrive directory should be enough to run your project because the rest of global dependencies, according to your logs, were successfully installed.

...ANSWER
Answered 2022-Jan-25 at 08:42There was a breaking change to the way DeflateStream operates in .NET 6. You can read more about it and the recommended actions in this Microsoft documentation.
Basically, you need to wrap the .Read operation and check the length read versus the expected length because the operation may now return before reading the full length. Your code might look like this (based on the example in the documentation):

I cannot decode valid compressed chunks from zlib stream using go's zlib package.
I have prepared a github repo which contains code and data illustrating the issue I have: https://github.com/andreyst/zlib-issue.
What are those chunks?They are messages generated by a text game server (MUD). This game server send compressed stream of messages in multiple chunks, first of which contains zlib header and others do not.
I have captured two chunks (first and second) with a proxy called "mcclient", which is a sidecar to provide compression for MUD clients that do not support compression. It is written in C and uses C zlib library to decode compressed chunks.
Chunks are contained in "chunks" directory and are numerated 0 and 1. *.in files contain compressed data. *.out contain uncompressed data captured from mcclient. *.log contain status of zlib decompression (return code of inflate call).
A special all.in chunk is chunk 0 concatenated with chunk 1.
mcclientsuccessfully decompresses input chunks with C'szlibwithout any issues.*.logstatus shows0which means Z_OK which means no errors in zlib parlance.zlib-flate -uncompress < chunks/all.inworks without any errors under Linux and decompresses to same content. Under Mac OS it also decompresses to same content, but with warningzlib-flate: WARNING: zlib code -5, msg = input stream is complete but output may still be valid— which look as expected because chunks do not contain "official" stream end.- Python code in
decompress.pycorrectly decompresses with bothall.inand0/1chunks without any issues.
See main.go — it tries to decompress those chunks, starting with all.in and then trying to decompress chunks 0 and 1 step by step.
An attempt to decode all.in (func all()) somewhat succeeds, at least decompressed data is the same, but zlib reader returns error flate: corrupt input before offset 446.
When trying real-life scenario of decompressing chunk by chunk (func stream()), zlib reader decodes first chunk with expected data, but returning an error flate: corrupt input before offset 32, and subsequent attempt to decode chunk 1 fails completely.
Is it possible to use go's zlib package in some kind of "streaming" mode which is suited for scenario like this? Maybe I am using it incorrectly?
If not, what is the workaround? Also it would be interesting to know, why is that so — is it by design? Is it just not implemented yet? What am I missing?
...ANSWER
Answered 2021-Dec-30 at 22:28Notice that error is saying that the data at an offset after your input is corrupt. That is because of the way your are reading from the files:
