Why the function `rpmUtils.arch.getArchList()` returns i386, i486, etc. arches?

I was looking for a way to download all the dependencies of an RPM. I found this link:

http://unix.stackexchange.com/questions/50642/download-all-dependencies-with-yumdownloader-even-if-already-installed/50671#50671

telling to do this:

repotrack -a x86_64 -p /repos/Packages [packages]

The author claims that there is a bug: indeed, this command will download RPMs with arch x86_64, but also i*86 arches.

Here is the list of arch returned by the function rpmUtils.arch.getArchList() for the given option -a x86_64:

['x86_64', 'athlon', 'i686', 'i586', 'i486', 'i386', 'noarch']

Is it a bug, or is there a real reason to download also all the packages with those different arches?

Here is the source of the function rpmUtils.arch.getArchList():

Thanks,

Hello,

Not sure if you still have this question.

Would try to answer. As per defination getArchList method would return arch compatible to arch you have provided, as per that I can see that it list all of below arch, as per method

`def getArchList(thisarch=None):

this returns a list of archs that are compatible with arch given`

# amd64
"x86_64": "athlon",
"amd64": "x86_64",
"ia32e": "x86_64",
"athlon": "i686",
"i686": "i586",
"i586": "i486",
"i486": "i386",
"i386": "noarch",

That really doesn't answer the question of why repotrack should be downloading compatible architectures, rather than just the architecture given (plus noarch). That is answered here: https://bugzilla.redhat.com/show_bug.cgi?id=1150115
