We are talking about the "preferred" default archive format in Distutils-SIG.

I was wondering if you could give us some statistics on the various archives format used at PyPI.

Here are some statistics:

total number of uploaded files: - .tar.gz or .tgz files: 16667 - .tar.bz2 files: 547 - .zip files: 2053 - .egg files: 10189 - .exe files: 1115 - .rpm files: 77 - .dmg files: 4 - .deb files: 1

total number of such files uploaded as source: - .tar.gz or .tgz: 16525 - .tar.bz2: 543 - .zip: 2046 - other source files: 6

number of packages that have uploaded such source files: - .tar.gz or .tgz: 4229 - .tar.bz2: 151 - .zip: 706

Some packages release more than one source file per release; it's difficult to compute statistics here, because these are sometimes just repackagings (e.g. Amara: both .tar.gz and .tar.bz2) and sometimes different sets of sources (e.g. 4Suite-XML: both program source, and -docs).

HTH, Martin
