git address in SRC_URI, doesn't works for me

git address in SRC_URI, doesn't works for me

[lei yang]

Hi experts.

One git address's prefix is "http" --->
http://git.opensvc.com/multipath-tools/.git,

it means

git clone  http://git.opensvc.com/multipath-tools/.git  ---------> works
git clone git://git.opensvc.com/multipath-tools/.git ---------> doesn't work

I tried SRC_URI with below, both failed

SRC_URI = "http://git.opensvc.com/multipath-tools/.git;protocol=git"
it tells
fatal: reference is not a tree: c23c0d33ed98a1dcee40115018b73cb3d4cda8d7


SRC_URI = "git://git.opensvc.com/multipath-tools/.git;protocol=http"
it doe noting,and trying to find COPING,but it doesn't clone it

any help?

This is the correct syntax. The URL scheme (git://) determines what bitbake
fetcher, and therefore what tool, is used to fetch. If you use http://,
it'll try to download it with wget, not git.

But, the fact is git://git.opensvc.com/multipath-tools/.git can't be
used, you can't  git clone  git://git.opensvc.com/multipath-tools/.git
(git:// is not valid this this git repos)
but you can "git clone  http://git.opensvc.com/multipath-tools/.git",
I think bitbake doesn't handle this

Correct, now it works for me, what protocol determines, , I thought
SRC_URS="address;protocol=*"
The address should be a real address, now I know it's not , a strange usage

Thanks

Yes, it is very counterintuitive (but cannot be corrected easily due to 
gazillions of recipes that use this unfortunate scheme).

As I already explained, the url scheme determines the tool to be used.
http:// will call wget. git:// will call git. protocol= controls the
underlying protocol it's fetched over. Not that complex. The alternative
would be to reverse them, meaning you'd have to tell bitbake not to use
wget for a http:// uri. Neither will magically know that a given
http://uri is a git repository.

I think you already got this answered on IRC, but for reference you need to 
use git://....;protocol=http and not http://.....;protocol=git. BitBake uses 
the prefix to determine which fetcher to use (matching the type of repository 
being fetched from) and then each individual fetcher decides the meaning of 
the protocol argument. In this case you're fetching from a git repository 
using the HTTP transport protocol.

Cheers,
Paul
