Mercurial Bundle Compression Error on Debian
If you get this error when pushing to a repository:
hg push pushing to https://mercuriate.3aims.com/project/... http authorization required realm: Dev Repo user: xxx password: searching for changes unknown bundle compression type
It is because you need to upgrade to mercurial 1.0 in backports:
$ wget http://www.backports.org/debian/pool/main/m/mercurial/mercurial-common_1.0.1-2~bpo40+1_all.deb $ wget http://www.backports.org/debian/pool/main/m/mercurial/mercurial_1.0.1-2~bpo40+1_amd64.deb $ dpkg -i mercurial-common_1.0.1-2~bpo40+1_all.deb mercurial_1.0.1-2~bpo40+1_amd64.deb
Building Firefox 3 on Mac OS X
First of all read the main build page at http://developer.mozilla.org/en/Mac_OS_X_Build_Prerequisites
I already have the following installed:
- The latest iPhone SDK 2.0 final (build 9M2199a) including XCode 3.1
- XQuartz 2.3.0 from http://xquartz.macosforge.org/trac/wiki
- The latest updates to Leopard (10.5.4)
Getting Started
Download and install MacPorts 1.6.0 for your platform from http://www.macports.org/install.php
Install packages needed for grabbing and building Firefox:
$ sudo /opt/local/bin/port sync $ sudo /opt/local/bin/port install mercurial libidl autoconf213
The second stage takes a long time because it builds lots of dependencies. It will stop three times while handling Python. Just keep running the command until everything works. Here’s the output I received:

Now get the Firefox source code using Mercurial:
hg clone http://hg.mozilla.org/mozilla-central
To build it you will need to modify your path to include the MacPorts software:
export PATH=$PATH:/opt/local/bin
Now you can start the build:
cd mozilla-central make -f client.mk build
This command will run for hours but when it is finished you will have a Firefox build.
Run the build in a terminal like this (you have to close any existing Friefox browsers though):
./obj-ff/dist/bin/firefox-bin
Run the debug build by clicking on the MinefieldDebug icon in the same directory.
And here it is running:
Mercurial Hosting using hg-admin-tools over SSH
In this article we’ll set up mercurial hosting over SSH. This is very similar to the Subversion setup described earlier but we’ll also make use of LShift’s hg-admin-tools to automate some parts of the set up.
I’ve got to say I don’t really understand the ssh-agent instructions from the README so this is my best stab. If it is wrong please let me know. There are some instructions here http://kb.iu.edu/data/aeww.html
First install mercurial, set up a new user and ensure you have Python 2.5:
apt-get install python2.5 python2.5-dev mercurial adduser hgadmin
Then give the hgadmin user sudo priviledges with visudo before becoming hgadmin and moving to the home directory:
visudo su hgadmin cd
Create a .ssh directory:
mkdir ~/.ssh
You’ll also need an updated version of mercurial otherwise an import fails later on:
wget http://www.backports.org/debian/pool/main/m/mercurial/mercurial_0.9.5-2~bpo40+1_amd64.deb sudo dkpg -i mercurial_0.9.5-2~bpo40+1_amd64.deb
At this point you need to have ssh-agent running and set up. Create a new key pair and copy the public key to the server like this:
james-gardners-macbook-air:~ james$ ssh-keygen -t dsa -f ~/.ssh/id_dsa -C "james@macbook.3aims.com" Generating public/private dsa key pair. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /Users/james/.ssh/id_dsa. Your public key has been saved in /Users/james/.ssh/id_dsa.pub. The key fingerprint is: 46:1e:48:06:b4:cd:ff:c7:e0:2e:db:77:59:5e:d0:0d james@macbook.3aims.com james-gardners-macbook-air:~ james$ scp ~/.ssh/id_dsa.pub hgadmin@78.47.146.254:.ssh/authorized_keys hgadmin@78.47.146.254's password: james-gardners-macbook-air:~ james$ scp ~/.ssh/id_dsa hgadmin@78.47.146.254:.ssh/ hgadmin@78.47.146.254's password:
Now you should be able to login as hgadmin using the password you set on your private key:
ssh hgadmin@78.47.146.254
Set up ssh-agent (I don’t know why we are doing this bit really but the install fails without it:
exec `ssh-agent` ssh-add
This will add the .ssh/id_dsa key to ssh-agent so that in the next step when we run install, it will be added correctly when the command ssh-add -L is called:
We need to get the hg-admin-tools:
mkdir ~/lib cd ~/lib hg clone http://hg.opensource.lshift.net/hg-admin-tools
Make sure there isn’t already an hg user then run this:
cd hg-admin-tools ./install
This creates a new user called hg without password signins and runs hginit to setup the hgadmin repository.
Changing Permissions
Now that the software is installed you need to know how to administer it. Back on the machine you signed in from (in my case the Macbook) you can checkout the hgadmin repository:
hg clone http://hg@78.47.146.254/hgadmin
This works because the same key you used for password-less signin to the hgadmin account has been setup by the hginit script to allow you to signin with the same key to the hg user account.
Creating New Repositories
Users authorized to do so (such as yourself) can create new repositories like this:
mkdir new-repository cd new-repository hg init hg clone . ssh://hg@78.47.146.254/my-project-name
You can then do things like this:
hg add * hg commit -m "Adding initial files" hg push ssh://hg@78.47.146.254/my-project-name
Then you can check out the changes somewhere else:
hg clone ssh://hg@78.47.146.254/my-project-name new-copy-of-my-new-project
or update another checkout with the new changes:
hg pull hg update
Each operation involving the server will prompt you for the password for your private key.
Back to the README
At this point you should be able to follow the README again. Particularly the HG-SSH-ACCESS.CONF section. It explains how you can add keys for new developers to the keys directory and configure permissions by changing the hg-ssh-access.conf. hen you check in changes some hooks are run to update the .ssh/authorized_keys file on the server to work with the new permissions.
Web Interface
Now let’s set up a web interface for the hosting. You can use hg serve to provide a web interface to a particular repository. For example to serve the new-project-name repository you would do this:
cd /home/hg/repos/new-project-name hg serve
This would start a server on http://localhost:8000 to serve the repository. You can also customise the styles. An easier style to use is gitweb:
hg serve --style gitweb
You can create your own styles by copying and modifying an existing template:
sudo cp -r /var/lib/python-support/python2.4/mercurial/templates/gitweb/ /var/lib/python-support/python2.4/mercurial/templates/james hg serve --style james
There’s documentation on how to do this at http://hgbook.red-bean.com/hgbookch11.html
