how to zlib inflate a gzip/deflate archive

Asked 2021-May-04 at 01:58

I have an archive encoded with gzip 1.5. I'm unable to decode it using the C zlib library. zlib inflate() return EC -3 stream.msg = "unknown compression method".

That should work fine, assuming that my_alloc and my_free do what they need to do. You should verify that you are actually giving unzip() the data that you think you are giving it. The data you give it needs to start with the 1f 8b.

(Side comment: "unzip" is a lousy name for the function. It does not unzip, since zip is an entirely different format than either gzip or zlib. "gunzip" or "ungzip" would be appropriate.)

You are manually reading the bits in the deflate stream in the wrong order. The least significant bits are first. The low three bits of ec are 100, indicating a non-last dynamic block. 0 for non-last, then 10 for dynamic.

You can use infgen to disassemble a deflate stream. Its output for the 14 bytes provided is this initial portion of a dynamic block:

R: Replace Abbreviations\ Words

Asked 2021-Feb-10 at 20:31

I have tried to resolve this problem all day but without any improvement.

I am trying to replace the following abbreviations into the following desired words in my dataset:

-Abbreviations: USA, H2O, Type 3, T3, bp

Desired words United States of America, Water, Type 3 Disease, Type 3 Disease, blood pressure

The input data is for example

[1] I have type 3, its considered the highest severe stage of the disease.
[2] Drinking more H2O will make your skin glow.
[3] Do I have T2 or T3? Please someone help.
[4] We don't have this on the USA but I've heard that will be available in the next 3 years.
[5] Having a high bp means that I will have to look after my diet?

The desired output is

[1] i have type 3 disease, its considered the highest severe stage of the disease.
[2] drinking more water will make your skin glow.
[3] do I have type 3 disease? please someone help.
[4] we don't have this in the united states of america but i've heard that will be available in the next 3 years.
[5] having a high blood pressure means that I will have to look after my diet?

If you need to replace only whole words (e.g. bp in Some bp. and not in bpcatalogue) you will have to build a regular expression out of the abbreviations using word boundaries, and - since you have multiword abbreviations - also sort them by length in the descending order (or, e.g. type may trigger a replacement before type three).

ZLIB inflate stream header format

...

ANSWER

Answered 2021-Feb-07 at 04:35

Your code is looking for a zlib stream header, as defined in RFC 1950. It's not finding it. That RFC defines the zlib header and trailer that is wrapped around a raw deflate stream.

You have a raw deflate stream in your question. To decode that instead of a zlib stream, you would need to use inflateInit2() with a windowBits value of -15.

QUESTION

C# proper way to construct ISerializable interface?

Asked 2020-Dec-13 at 10:49

I recently made my own custom formatter, it takes a runtime object and writes down an object graph of it in a string format then takes that string and converts it back to a runtime object. Example: [CustomFormatter.Btype, CustomFormatter, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null==[a==5][b==0]]

after messing around with primitive objects (int, bool, float...) I tried to serialize a Bitmap object into string using the ISerializable interface and it worked well but when I try to reconstruct the object back I'm getting an error System.MissingMethodException: Constructor on type 'System.Drawing.Bitmap' not found.

If bitmap doesn't have a constructor which takes SerializationInfo and StreamingContext as parameters how else can an object which inherits the ISerializable interface be constructed?

This part is is the main issue but I can include the whole code:

ANSWER

Answered 2020-Dec-13 at 10:49

If you are forced to for legacy .NET Framework reasons, and you are taking over the role of the serializer engine: you can construct raw objects using FormatterServices.GetUninitializedObject. This API is explicitly intended for use with things like serialization, but should be treated as an advanced/exotic feature, and needs great care. Bad things can happen in some cases (fields not initialized, etc).

Quite honestly there is no correct way of working with the ISerializable interface in 2020 - that entire API is deprecated and obsolete, and isn't widely supported in .NET Core / .NET 5, and I would not recommend starting new work with it. More details about the problems/reasons are here: https://blog.marcgravell.com/2020/03/why-do-i-rag-on-binaryformatter.html, and many other, non-deprecated, serialization frameworks exist.

How to decode deflate block header from the deflate compression output result

ANSWER

Answered 2020-Oct-30 at 13:51

You are making a zlib stream, not a raw deflate stream. So the 78 da is the zlib header, not deflate compressed data. The deflate data starts with f3. The low three bits of that are 011. The low 1 is BFINAL (this is the last block), and the 01 is BTYPE (fixed Huffman codes).
