In a previous post I talked about setting up an encrypted file based keyring store for Mercurial. With some recent updates of the Python keyring modules, the setup changed a little bit again.
The file-backed keyrings got moved out to the keyrings.alt package.
$HOME/.local/share/python_keyring/keyringrc.cfg needs to be adjusted as follows:
In an earlier post I documented how to set up an encrypted file store for your keyring. With recent versions of Python keyring (at least 3 and up) the
CryptedFileKeyring backend got removed and replaced by
EncryptedKeyring. So in your
$HOME/.local/share/python_keyring/keyringrc.cfg you need to now have the following:
Mercurial allows for tying in keyring configuration for those of us who do not want to store passwords in plain-text in our
.hgrc files or constantly using SSH.
First install the Python keyring library by running
pip install keyring. After that is installed, checkout https://bitbucket.org/Mekk/mercurial_keyring/ and add to
$HOME/.hgrc the following:
mercurial_keyring = ~/path/to/mercurial_keyring/mercurial_keyring.py
Next up, configure your repositories, e.g. in the case of Bitbucket I use:
bitbucket.prefix = bitbucket.org/asmodai
bitbucket.username = asmodai
bitbucket.schemes = https
Mercurial keyring will automatically decide on the best keyring to use. On a FreeBSD system with no Gnome or other systems providing a keyring, if you do not specify a specific keyring, the system will use the file
~/.local/share/python_keyring/keyring_pass.cfg. This keyring file stores the passwords encoded in Base64 in plain-text. This is not quite what you would want from a security point of view. You can configure which backend store to use by editing
$HOME/.local/share/python-keyring/keyringrc.cfg. To get a plain-text file with encrypted keys use the following configuration:
This will create the file
~/.local/share/python-keyring/crypted_pass.cfg after initializing the backend store with a password. Look at the documentation for keyring on what other configuration options are available.
Note: make sure the PyCrypto dependency is installed with the
_fastmath module. This in turn depends on the
If you have a Subversion repository setup with multiple top-level projects and their typical branches/tags/trunk setup and want to migrate these to individual Mercurial (Hg) repositories, you can do this with the convert extension.
First you need to enable convert in your
.hgrc by adding a section like the following:
Next, if needed, create a plain-text file, e.g. author-map.txt, containing SVN username to Hg author mappings, e.g.
asmodai=Jeroen Ruigrok van der Werven <email@example.com>.
Next run Hg as follows:
hg --authors author-map.txt --config convert.svn.branches=project/branches --config convert.svn.tags=project/tags --config convert.svn.trunk=project/trunk path/to/svn/repository path/to/destination/hg/repository
This will start a SVN to Hg conversion, picking up only the changes and commit messages applicable for the various paths you gave for the branches, tags, and trunk, effectively splitting off this project from the main SVN tree into its own Hg repository.
Do note that for large SVN repositories this might not be the most efficient conversion way forward. In that case converting once from SVN to Hg and then split off Hg into many Hg repositories might be faster. Will adjust this post when I write that up.
For my own sanity:
In order to change the parent repository URL of a Mercurial clone (as
svn switch does) one simply edits
.hg/hgrc and adjusts the
