How can I 'hg clone' from another machine? - mercurial

I have 2 Ubuntu laptops in the same WiFi network. I would like to 'hg clone' from 1 laptop to another.
In my source laptop,
I have a 'hg' repository in ~/work/myserver
and my source laptop ip address inet addr:192.168.1.2.
So what should i do on my dest laptop so that I can clone my hg repository?
Thank you.

Like so:
hg clone ssh://your-user#192.168.1.2//home/my-user/work/myserver/
Note: If you're running a firewall on 192.168.1.2, you'll need to open port 22 for SSH. I believe Ubuntu uses ufw by default.
Note 2: Replace your-user with the user you use to login when you're sitting at 192.168.1.2

My choice between two Linux computers would also be going through ssh, as suggested by Zack.
One alternative that also works on Windows machines is to use the integrated web server to expose your repository, then clone from there.
First you run hg serve that will by default get you a web server on port 8000, then you just hg clone http://machine1:8000, with the added benefit that you get a nice graphical view of your history. (more information here)

Git must be used for Scalable App?

I am trying to move an old Wordpress install to Openshift.
So I setup two gears, one running MySQL (Gear #1) and the other is setup to be a scalable PHP5 gear (Gear #2). I have manually restored the database data to Gear #1 and manually restored original Wordpress files in Gear #2 under ~/app-root/runtime/repo. The app is running fine now with everything in place.
However, when I try to raise the max number of scalable PHP5 gears from 1 to 2, the app stopped working and showing only the default gear landing page, just like what an empty gear would show. Setting maximum scalable gears back to 1 then the app would work again.
Is it true that the Wordpress files (or any other PHP or web files under ~/app-root/runtime/repo) must be checked in with Git in Gear #2, in order for scaling up to Gear #3+ to work properly? If so, is there anyway I can check-in the files that I already have in Gear #2 from within itself? If not, how can I check-in the set of files that I already have from the old Wordpress install?
Thank you for your help in advance!
Cheers,
KC
If you want to get the files on your web gear into git you have two options:
1.) SSH or SFTP into your gear and copy the files to your local workstation, then clone your git repo to your local machine, and copy the files into it, git commit & git push. Then your files will be deployed properly.
2.) SSH into your gear, initialize a git repo in your app-root/repo folder, and then setup your git repo in that gear (the one openshift created) as a remote and add/commit/push your files, then you can do a clone on your local workstation and a push and everything should deploy correctly.
I spoke with operations about this:
We do an rsync from the app-deployments directory, which are the files that were in git. So it does seem at this point that git must be used for scaled applications to work correctly. Please add your use case to http://openshift.com/ideas

Gitlab with non-standard SSH port (on VM with Iptable forwarding)

My gitlab is on a virtual machine on a host server. I reach the VM with a non-standard SSH port (i.e. 766) which an iptable rule then forward from host:766 to vm:22.
So when I create a new repo, the instruction to add a remote provide a mal-formed URL (as it doesn't use the 766 port. For instance, the web interface give me this:
Malformed
git remote add origin git#git.domain.com:group/project.git
Instead of an URL containing :766/ before the group.
Wellformed
git remote add origin git#git.domain.com:766/group/project.git
So it time I create a repo, I have to do the modification manually, same for my collaborator.
How can I fix that ?
In Omnibus-packaged versions you can modify that property in the /etc/gitlab/gitlab.rb file:
gitlab_rails['gitlab_shell_ssh_port'] = 766
Then, you'll need to reconfigure GitLab:
# gitlab-ctl reconfigure
Your URIs will then be correctly displayed as ssh://git#git.domain.com:766/group/project.git in the web interface.
if you configure the ssh_port correctly in config/gitlab.yml, the webpages will show the correct repo url.
## GitLab Shell settings
gitlab_shell:
...
# If you use non-standard ssh port you need to specify it
ssh_port: 766
ps.
the correct url is:
ssh://git#git.domain.com:766/group/project.git
edit: after the change you need to clear caches, etc:
bundle exec rake cache:clear assets:clean assets:precompile RAILS_ENV=production
N.B.: this was tested on an old Giltab version (v5-v6), and might not be suitable for modern instance.
You can achieve similar behavior in a 2 step process:
1. Edit: config/gitlab.yml
On the server, set the port to the one you use:
ssh_port: 766
2. Edit ~/.ssh/config
On your machine, add the following section corresponding to your gitlab:
Host sub.domain.com
Port 766
Limit
You will need to repeat this operation on each user's computer…

Easy way to fix this issue:
ssh://git#my-server:4837/~/test.git
git clone -v ssh://git#my-server:4837/~/test.git

Mercurial over ssh with config file

Say I have the following ssh .config file:
Host host_nickname
User xxx
HostName yyy.zz.vvv
ControlMaster auto
ControlPath ~/.ssh/%r#%h:%p
In case you are not familiar with ControlMaster or ControlPath, here is the description from the ssh_config manual:
ControlMaster:
Enables the sharing of multiple sessions over a single network
connection. When set to ``yes'', ssh(1) will listen for connec-
tions on a control socket specified using the ControlPath argu-
ment. Additional sessions can connect to this socket using the
same ControlPath with ControlMaster set to ``no'' (the default).
These sessions will try to reuse the master instance's network
connection rather than initiating new ones, but will fall back to
connecting normally if the control socket does not exist, or is
not listening.
In Mercurial, if you want to push or pull from a repository, you could just type the following:
hg push ssh://user#example.com/hg/
Now, my question:
I would like to ask Mercurial to push (or pull) against a repository at /path/to/repository on the server corresponding to my ssh config entry host_nickname. How do I do this?
If you look under hg help urls you'll find
ssh://[user#]host[:port]/[path][#revision]
So, assuming that /path/to/repository works from your login dir on the remote machine, then type
hg [push|pull] ssh://host_nickname/path/to/repository
This works because hg isn't doing the name resolution; ssh is, and you've specified the correspondence between host_nickname and the real HostName. Also, ControlMaster won't affect this, as that just allows multiplexing over a single ssh connection. Note, if hg isn't in your remote PATH, then you need to specify it via --remotecmd /path/to/hg.

scp a mercurial repository

I have a shared web host and I am trying to figure out a way to download the latest copy of a private project from bitbucket onto the server.
The server does not have any versioning tools installed, but it does have scp and ssh with a jailshell level of access. It also has wget and curl...
Can I can do something like this?
scp ssh://hg#bitbucket.org/jespern/testrepo ~/public_html
I don't have a problem setting up the identity files / DSA keys, but I'm not exactly sure how the protocols are put together here so I need some help with the basic syntax.
Or, if scp is not the way to go, does ssh have an option for doing this? or is it possible to use CURL or wGet to grab the latest version of the repository and then reconstruct it on the server?
I am sure there is a way to do this, so please don't respond saying "it can't be done."
Thanks!
You can download from bitbucket using either http with URL like this:
http://bitbucket.org/jespern/rewsfeed/get/tip.tar.bz2
Notice how tip can be used in place of a revision ID in that URL form to always get the latest snapshot.
Alternately, you can just install Mercurial in your home directory on the shared web host -- people have succeeded in doing that on almost every webhost out there no matter how locked down they are.
Then you can just do: /home/me/bin hg clone ssh://hg#bitbucket.org/jespern/testrepo ~/public_html

How to configure hosted Mercurial in TeamCity 5

This is probably a simple problem and I'm feeling exceptionally dumb because I can't find a any kind of documentation.
I've just installed TeamCity 5 and I want to get files from my Mercurial hosting and there is two fields I just can't figure out.
HG Command path. What should I put here? The path to a file containing what? Can I get an example of that file somewhere?
The host is using Mercurial over SSH where do I define my private key?
Pull changes from? Should I put the address I'm cloning from i.e. ssh://username#myhost.something/project
I figured this out for my TeamCity 5 server last week.
HG Command path: HG
Pull changes from: https://bitbucket.org/.../.../
Don't put the username# in the URL. This is specificed as in the Username/Password fields. If you include the username in the URL it'll fail as there is a bug in the configuration tool. You'll also see a screenshot of the configuration attached to the thread:
http://www.jetbrains.net/devnet/message/5254640#5254640
I'd suggest getting things working with HTTPS and then moving to SSH if possible. This breaks things down into two easier to solve configuration problems. I used the following tutorial to get SSH going on my Windows client machine.
http://www.codza.com/mercurial-with-ssh-setup-on-windows
I've not set this up on my TeamCity server yet. However I did get TeamCity to pick up my Mercurial.ini settings by putting the ini file in \Documents and Settings\TeamCity, which is the account the service runs under.
I've not used team city, but I think hg command path is probably the full path to your local mercurial executable. For me (on linux) that's:
$ type hg
hg is /usr/bin/hg
On windows it's where the 'hg' executable in your system path was placed by whichever (of the many) windows installers for mercurial you used.
Pull changes from sounds like the URL to the repo, so:
ssh://username#myhost.something/project
or
ssh://username#myhost.something//project # note the _two_ double slashes
if you're using absolute paths on the server side.
Your private key location/specification depends on what you're using for ssh and whether or not you're running ssh-agent, but here's a links that explicitly points from within mercurial.ini, which seems sound:
