Description Ravi Vikkram 2022-06-20 09:30:13 UTC 
As We do develop software with multiple company collaboration, company A stores all the software Sources in GIT SCM and company B mirrors the repository in the their GIT SCM. The bb files reference the GIT SCM of the company A , the developers from the company B still fetch the source from the GIT SCM of the company A and not the mirror repository of the company B. 

Git mirroring is when a mirror copies the refs & the remote-tracking branches. It is  functionally identical copy that is interchangeable with the original.

What did I try already :


PREMIRRORS_append += "git://git@git.abc.a.com:8080/.* git://abc.b.com/repos/projects/k/.*\n"

A premirror append always look for tar file of the source repository. 

Expectation:

I want to replace the domain name of the company A with the company B so that I could use both the repository in each of its domain.

Can you give a little more information about why/how that failed?

In theory you should be able to setup a PREMIRROR entry as you describe. It would look for mirror tarballs but should also try the full url replacement as you want.

I assume you're using an older release and hence the "_append" syntax rather than ":append"? That syntax wouldn't work with 4.0.

We do various manipulations such as adding a ;protocol=https fallback for ;protocol=git:

https://git.yoctoproject.org/poky/tree/meta/classes/mirrors.bbclass#n76

so your case should be simpler and also work.

As per Richard's comments, need info state.
Comment 3 Ravi Vikkram 2022-06-24 05:56:24 UTC 
I have updated the version of the Poky Distro version to 3.1.15
Comment 4 Ravi Vikkram 2022-06-27 09:43:00 UTC 
I have added to the required information
Comment 5 Richard Purdie 2022-06-27 18:57:34 UTC 
Thanks for the additional information, it helps a lot to know this is dunfell. Even in dunfell, the MIRRORS entries I mentioned are present though:

https://git.yoctoproject.org/poky/tree/meta/classes/mirrors.bbclass?h=dunfell#n73

so in theory mapping two urls like that should work. 

We need to establish what exactly isn't working. Do you have a fetch log and PREMIRRORS entry which shows what is being attempted/not attempted you could share please?

In your example I notice that the domains, user, path and ports are different so it could be able one of these that is the trigger for an issue.

Ravi, see Richards comment and please reply.
Comment 7 Ravi Vikkram 2022-07-18 14:52:54 UTC 
The above solutions worked for me with the example shown in the bbclass. Thank you
Comment 8 Ravi Vikkram 2022-08-09 03:56:20 UTC 
The solution does work on the version. Thanks . Hence I mark it as not a Bug
