[issue37095] [Feature Request]: Add zstd support in tarfile

2020-08-29 Thread Ma Lin 


Ma Lin  added the comment:

I have spent two weeks, almost complete the code, a preview:
https://github.com/animalize/cpython/pull/8/files

Write directly for stdlib, since there are already zstd modules on pypi.
In addition, the API of zstd is simple, not as complicated as lzma.

Can also use these:
1, argument clinic
2, multi-phase init
3. internal function _PyLong_AsInt

[issue37095] [Feature Request]: Add zstd support in tarfile

2020-08-15 Thread Ma Lin 


Ma Lin  added the comment:

There are two zstd modules on pypi:

https://pypi.org/project/zstd/
https://pypi.org/project/zstandard/

The first one is too simple.

The second one is powerful, but has too many APIs:
ZstdCompressorIterator
ZstdDecompressorIterator
ZstdCompressionReader
ZstdCompressionWriter
ZstdCompressionChunkerIterator
(multi-thread compression)

IMO these are not necessary for stdlib.

In addition, it needs to add something, such as the `max_length` parameter, and 
a `ZstdFile` class that can be integrated with the tarfile module. These 
workloads are not big.

I looked at the zstd API, it's a bit simpler than lzma/bz2/zlib. If spend a 
month, should be able to make a zstd module for stdlib. Then discuss the 
detailed API on Python-Ideas.
 
I once wanted to do this job, but it seems my time does not allow it. If anyone 
wants to do this work, please reply here.

FYI, Python 3.10 schedule:
3.10.0 beta 1: 2021-05-03 (No new features beyond this point.)

2020-07-23 Thread Serhiy Storchaka 


Serhiy Storchaka  added the comment:

The tarfile module supports arbitrary compressions by using the stream mode. 
You only need to use a third-party library which provides zstd support.

Recent versions of the tar utility has options to explicit support of new 
compressions: --lzip, --lzma, --lzop, --zstd, so corresponding modes can be 
added to the tarfile module. But it needs to include the support of these 
compressions in the stdlib. It should be discussed on the Python-ideas mailing 
list.

> Add zstd support in tarfile

This requires the stdlib to contain a Zstandard module.

You can ask in the Idea forum:

Anatol Pomozov  added the comment:

Is there any progress with this feature development?

Arch Linux uses Python tar library for its toolset. Arch devs are looking to 
add ZSTD support to the toolset but it needs this feature to be implemented.

New submission from Evan Greenup :

Zstandard is getting more and more popular. It could be awesome if tarfile 
support this compression format for .tar.zst file.
