Hello,

i have a repo 'main_gerrit' which i want to replicate to a stash Server.

Here is the replication.config

[remote "stash"]

url = ssh://jen...@domain.com:7999/gpoc/${name}.git

push = +refs/heads/*:refs/heads/*

push = +refs/for/*:refs/for/*

push = +refs/drafts/*:refs/drafts/*

push = +refs/tags/*:refs/tags/*

authGroup = Registered Users

threads = 1

and when the replication starts then it is trying to replicate all repos that are on my Gerrit Server...

The problem was on the stash side - missing permissions.

Still - how will i be able to narrow the replication only to specific repos i want...?

Solved.

Found the solution in this thread - https://groups.google.com/forum/#!topic/repo-discuss/GICfb28Xbow

All you have to do is adding the "projects" attribute to the replication.config in order to explicitly set the projects to be replicated.

[remote "hostname"] 
  url = gerrit@hostname/test/git/${name} 
  projects = your_project_name

Here is the part in Documentation which explain it (I missed it before.....)

https://review.typo3.org/plugins/replication/Documentation/config.html

remote.NAME.projects
Specifies which repositories should be replicated to the remote. It can be provided more than once, and supports three formats: regular expressions, wildcard matching, and single project matching. All three formats match case-sensitive.
Values starting with a caret ^ are treated as regular expressions. ^foo/(bar|baz) would match the projects foo/bar, and foo/baz. Regular expressions have to fully match the project name. So the above example would not match foo/bar2, while ^foo/(bar|baz).* would.
Values that are not regular expressions and end in * are treated as wildcard matches. Wildcards match projects whose name agrees from the beginning until the trailing *. So foo/b* would match the projects foo/b, foo/bar, and foo/baz, but neither foobar, nor bar/foo/baz.
Values that are neither regular expressions nor wildcards are treated as single project matches. So foo/bar matches only the project foo/bar, but no other project.
By default, replicates without matching, i.e. replicates everything to all remotes.

Thanks Doron,
How about the push tag??
Should i mention any specific branch in this?

My replication.config looks like
[remote "testreplica164"]
url = ger...@14.142.24.164:8080:/home/gerrit2/gerrit_testsite/git//${name}.git

projects = tmp_replica
push = +refs/heads/android-5.1.1_r24_new:refs/heads/android-5.1.1_r24_new
push = +refs/tags/*:refs/tags/*
threads = 4

android-5.1.1_r24_new : this is branch in tmp_replica project.
Is this replication.config ok?

Hi Doron,

Also I have one more query.
Currently on the host server I have 3 repositories kitkat, jellybean, lollipop. These are the folders present in gerrit_testsite/git on master server

Now I want to replicate only Lollipop project. Should i create a mirror on the slave machine first and then try to replicate ??
Should the folder name be lollipop on both master and slave servers??
Because replication is not creating any folder on slave machine by itself.
If my question is not clear, I can explain again.
Please help me

As i am not so experienced with the replication git (just started using it 1 month ago) I am not sure I can assist you, but I will try.

The push tag seems to be fine if the only branch that you want to replicate is the one you mentioned.

I think that you do not need to create such repository on the target as I know that by default there is a feature of the plugin that create missing repositories (the attribute of it is called createMissingRepositories and it is true by default)

Thanks Doron.
Now The replication is success.
But in the replication_log,
[4ad5d5dc] Push to ger...@14.142.24.164:8080:/home/gerrit2/gerrit_testsite/git/tmp_replica/platform/packages/apps/Browser.git references: [RemoteRefUpdate[remoteName=refs/heads/android-5.1.1_r24_new, NOT_ATTEMPTED, (null)...d16aaec37d44ab1b200b4c799feacc6a7f873af7, srcRef=refs/heads/android-5.1.1_r24_new, forceUpdate, message=null], RemoteRefUpdate[remoteName=refs/changes/90/1090/1, NOT_ATTEMPTED, (null)...d16aaec37d44ab1b200b4c799feacc6a7f873af7, srcRef=refs/changes/90/1090/1, forceUpdate, message=null]]
[2015-11-02 06:52:28,729] [4ad5d5dc] Replication to ger...@14.142.24.164:8080:/home/gerrit2/gerrit_testsite/git/tmp_replica/platform/packages/apps/Browser.git completed in 3105 ms

do you have any idea on What is this NOT_ATTEMPTED?

Even though replication is success, the code is not synced in the slave server.

Thanks

are you sure that on the target side the user that does the replication has the required authorizations?

Yes Doron,
the user has permission.
Because now i tried, using same replication.config and replication could create the repository by itself on the slave server.
1. But in the repository created on the slave server, I cannot find manifest.xml , default.xml inside the replicated repository (Inside .repo folder)
I am new to replication. Even i am unable to see the branches in this replicated repository.
2. Can we clone the code from this replicated repository?

Can you confirm that you do see the branches from A replicated to B but the files are not there?

Can you create a new branch on A and then check if it was replicated to B?

Hi Doron,

No. Branches present in A is not replicated to B.

Have you already tried replication? Is there manifest.xml inside your replicated repository's .repo folder??
