[issue20741] Documentation archives should be available also in tar.xz format

[Éric Araujo]

Éric Araujo  added the comment:

tar is modular and depends on optional external programs to handle compression 
(tar itself does archival only).

gzip is still common, and xz has largely replaced bz2 these days.
I would expect it to be installed on most systems.

(For HTTP compression there are new competitors, brotli and zstd, but I haven’t 
seen these used to compress files.)

[Terry J. Reedy]

Terry J. Reedy  added the comment:

https://docs.python.org/3/download.html says a) tar.bz2 can be read by the tar 
program, which I presume is true also of tar.xz.  So there is no issue of 
*needing* two separate programs.  It also claims "The .tar.bz2 archives provide 
the best compression and fastest download times."  This only need be true, if 
it is, for the doc formats, as opposed to python code.  In the absence of at 
least 2 requests from *nix consumers of the archives, why even think of 
changing?

Éric Araujo  added the comment:

Oh to counter my own proposal: formats should not be removed without warnings, 
there are probably downstream tools that expect specific URL patterns and 
formats.  So adding something very modern to get the smallest size might be 
good, but not removing existing format without warning.

Éric Araujo  added the comment:

I don’t think that consistency or standardization really applies here, it’s not 
like there are tools that want to process both source and doc archives and are 
broken by the difference in formats.

It could be useful to review the formats used and decide if they are still the 
best choices (maybe zip for universality, tar + modern and well-supported 
compression for size), but consistency for consistency’s sake is needless churn.

Ned Deily  added the comment:

Documentation downloads are still built and provided for each release (as 
linked to from https://www.python.org/doc/ and 
https://www.python.org/doc/versions/) as well as daily for the heads of each 
active bugfix and feature branch, in each case via the "Download these 
documents" link on the top page of the release/branch documentation set, for  
example, https://docs.python.org/3/ -> https://docs.python.org/3/download.html. 
The downloadable doc formats are still .zip and .bz2 while cPython source 
archives are still .tgz and .xz formats. Julien Palard (@mdk) is the release 
team documentation expert.  Julien, what do you think?

Those archives seem to go only up to 3.9. Is this still relevant?

Paul Anton Letnes added the comment:

The format (xz vs bzip2) might not matter much, but I'd say consistency does. 
I'd make the formats identical just for the sake of standardization.

Where is this decided? In some (post)build script?

[issue20741] Documentation archives should be available also in tar.xz format

[Arfrever Frehtes Taifersar Arahesis]

New submission from Arfrever Frehtes Taifersar Arahesis:

Source archives (e.g. in [1]) are available in tgz and tar.xz formats, but 
documentation archives (e.g. in [2]) are available only in tar.bz2 and zip 
formats.
I suggest that documentation archives be available also in tar.xz format.
