In github, my account can access multiple related repositories. A user story can be implemented as same-name branches in multiple repositories.
Given a branch's name, can I find out which repositories contain a branch with the given name?
Can I further jump to such a branch in a given repository?
Probably the simplest way of searching repositories for branch names is to use the command git branch within each repo. You can specify git branch -a for local and remote branches, or git branch -r for just remote.
This isn't ideal for a number of reasons, one being that you'd need to have command-line access to all the repositories you want to search (such as all the repos being cloned locally), another being that you'll have to manually scan through the branch list that git branch outputs.
One possible solution to this is to use the GitHub API to list all repos and / or all branches. The answer here gives a decent example in Python of how to authenticate (to allow access to private repos), which you would need to follow with the API's GET request:
GET /repos/:owner/:repo/branches

this might not sound too practical
but i want github collaborators to only be able to modify / make changes to the files that they themselves uploaded on the repository
they should not be able to replace, rename, edit or modify files uploaded by other collaborators in the same repository
is this possible to achieve in a private repository on github ?
If so, how can i do this ?
Git operates at a repository level, so if a collaborator can push to a repository, they can clone, modify locally any file and push back.
You can isolate their work through fork and pull request.
And use an GitHub action like check-new-commits (modify for your purpose) to check if each commits only includes files whose list of authors is limited to one.
I have a project on GitHub, and I forked it to a second repository.
There is still work done on the repo that I forked from, but the changes I make to the first repo should also be applied to the forked one.
How can I push a pull request to both of them at the same time? Or is that impossible to do in a simple way?
If it is, is there a simple alternative solution?
No, GitHub pull requests only target a single repository.
Pull requests are only relevant when you are communicating with other people. Since both repositories are yours, you can just execute a git pull or git merge command on your local machine to merge whatever branches you want to merge. Then use git push to push the changes up to GitHub if you want.
Also, I recommend that you simplify this setup and just use a single GitHub repository with multiple branches.
Background
I am using GitHub Enterprise.
I want to check unused branches in my repository, and ask owners of these unused branches to clean-up.
You can see "Your branches" (branches created by current user) on “Branches” page in GitHub. So I think GitHub might have information for who created a branch.
On the other hand, the result of GitHub REST API (https://developer.github.com/v3/git/refs/#get-a-reference) does not contain the creator of the specified branch.
Question
Is there’s any way to get the user who created a branch with GitHub API?
There is no real "ownership" associated to a branch with Git/GitHub.
As mentioned in the documentation, "Your branches" reference in a repository the branches you have push access to, not necessarily the ones you have "created".
The best you can do is, if you have access to a local clone, a simple git fetch, followed by:
git for-each-ref --format="%(committerdate) %09 %(refname:short) %09 %(authorname)" --sort=-committerdate refs/remotes/origin
That will list the remote branches from the most recent updated one to the oldest, with the author of the last commit on each branch.
But if you have to use GitHub API, then you would need to:
list the remote branches,
then for each one get the commit mentioned with the branch
You can then contact the committer of that most recent commit.
How do I create a github mirror for an external git repository, such that it appears as "real mirror", e.g., as in https://github.com/mirrors?
So far, I set up a mirror using:
cd /path/to/bare/repository
git remote add --mirror github git#github.com:user/repo.git
and configure the post receive hook to do a git push --quiet github. This way, however, github does not recognize the mirror.
Any ideas how to do it the github way, such that "Mirrorred from" appears underneath the repostiory name?
Based on communicating with GitHub's support team, I found that GitHub currently offers no direct mechanism for a user to mirror repositories in this fashion.
However, one can ask GitHub to install this service for repositories which are part of an organization. GitHub then configures an existing repository as such a mirror and pulls from it in an interval that is a function of the number of overall mirrors they have.
EDIT: as Stuart points out, GitHub no longer accepts requests for mirroring arbitrary repositories. The only remaining option is the solution I posted in my question, i.e., creating a post-receive hook to automatically push to your GitHub repository.
Judging by the current content of https://github.com/mirrors, it would appear GitHub no longer does "official mirrors", as most projects that want their code mirrored on GitHub today just makea an organization for it, such as Git itself.
There is also a feature request at: https://github.com/isaacs/github/issues/415
According to Importing a Git:
For purposes of demonstration, we'll use:
An external account named extuser
A GitHub personal user account named ghuser
A GitHub repository named repo.git
The command line:
# Makes a bare clone of the external repository in a local directory
$ git clone --bare https://githost.org/extuser/repo.git
# Pushes the mirror to the new GitHub repository
$ cd *repo.git*
$ git push --mirror https://github.com/ghuser/repo.git
# Remove the temporary local repository.
$ cd ..
$ rm -rf repo.git
I have used a tool called github-backup with moderate success to, if not mirror, at least make a full backup (including issues and other metadata) of a Github user or organization. To quote the README file:
Each time you run github-backup, it will find any new forks on GitHub. It will add remotes to your repository for the forks, using names like github_torvalds_subsurface. It will fetch from every fork.
It downloads metadata from each fork. This is stored into a branch named "github". Each fork gets a directory in there, like torvalds_subsurface. Inside the directory there will be some files, like torvalds_subsurface/watchers. There may be further directories, like for comments: torvalds_subsurface/comments/1.
You can follow the commits to the github branch to see what information changed on GitHub over time.
The format of the files in the github branch is currently Haskell serialized data types. This is plain text, and readable, if you squint.
Limitations include:
no private repository support
no "social" stuff like stars, followers, etc
notes to lines of commits are not supported (yet?)
issue labels
Imagine situation like this:
You have a working repo in bitbucket - you were pulling revisions from another bitbucket repo in Windows 7 through TortioseHG.
Now the second project has moved to Github system and you can not pull from it anymore.
So my question is like this:
How can i somehow create new repo in bitbucket where I will pulling changes from github and from this repo i can easily pull in Tortiose HG to my working repo?
I do not want to use Github etc, so please do not advice it to me etc just help me with my question. Thank you.
The ideal solution consiste to keep local Mercurial repo, and work only with this local repo to the existing bitbucket Mercurial remote repo.
With a plugin like Hg-Git, you can at least push to and pull from a Git server repository from Mercurial, allowing you to pull from the GitHub repo to your local Mercurial repo.
From that local (Mercurial) repo, you can then work as usual with the bitbucket remote repo.
The OP adds:
It didn't work for me so i tried to transfer git repo to hg repo and from this repo pull to my working repo with changes - but it says that: abort: repository is unrelated - but I merged a lot from it. Any help here?
That makes senses, if both repos have been developed separately, you cannot push/pull 2 (mercurial) repos one into another.
This is confirmed at the bottom of the page "Understanding Mercurial", and detailed in the blog post: "What Mercurial Can't Do: Subtree Repos".
The more practical solution would be to make one extra repository (a "parent one") with your two repos declared in it as nested repository.
It would keep both repos independent, allowing to push back to the GitHub repo from your second mercurial repo.
If you don't have to push back to GitHub, but really want to have one repo in which you merge common files, then you can look in "Merge tip from an unrelated repository with Mercurial", but that is much more complex.
I would rather:
keep both repos separate
delete from the first one the common files you need to merge in the second one.
report and merge those common files in the second one.
