mercurial_keyring Description

Mercurial Keyring Extension mercurial_keyring is a Mercurial extension that can be used to securely save HTTP and SMTP authentication passwords in password databases (Gnome Keyring, KDE KWallet, OSXKeyChain, specific solutions for Win32 and command line). This extension uses and wraps services of the keyring library.How does it workThe extension prompts for the password on the first pull/push (in case of HTTP) or first email (in case of SMTP), just like it is done by default, but saves the password. On successive runs it checks for the username in .hg/hgrc, then for suitable password in the password database, and uses those credentials (if found).In case password turns out to be incorrect (either because it was invalid, or because it was changed on the server) or missing it just prompts the user again.Passwords are identified by the combination of username and remote repository url (for HTTP) or username and smtp server address (for SMTP), so they can be reused between repositories if they access the same remote repository.InstallationPrerequisitesInstall the keyring library:easy_install keyring(or pip keyring). On Debian "Sid" the library can be also installed from the official archive (packages python-keyring and either python-keyring-gnome or python-keyring-kwallet).Extension installationThere are two possible ways of installing the extension: using PyPi package, or using individual file.To install as a package use easy_install:easy_install mercurial_keyringand then enable it in ~/.hgrc (or /etc/mercurial/hgrc) using:mercurial_keyring =To install using individual file, download the mercurial_keyring.py file, save it anywhere you like, and put the following in ~/.hgrc (or /etc/mercurial/hgrc):hgext.mercurial_keyring = /path/to/mercurial_keyring.pyPassword backend configurationThe library should usually pick the most appropriate password backend without configuration. Still, if necessary, it can be configured using ~/keyringrc.cfg file (keyringrc.cfg in the home directory of the current user). Refer to keyring docs for more details.I considered handling similar options in hgrc, but decided that single user may use more than one keyring-based script. Still, I am open to suggestions.Repository configuration (HTTP)Edit repository-local .hg/hgrc and save there the remote repository path and the username, but do not save the password. For example:myremote = https://my.server.com/hgrepo/someprojectmyremote.schemes = http httpsmyremote.prefix = my.server.com/hgrepomyremote.username = mekkSimpler form with url-embedded name can also be used:bitbucket = https://User@bitbucket.org/User/project_name/Note: if both username and password are given in .hg/hgrc, extension will use them without using the password database. If username is not given, extension will prompt for credentials every time, also without saving the password.Repository configuration (SMTP)Edit either repository-local .hg/hgrc, or ~/.hgrc and set there all standard email and smtp properties, including SMTP username, but without SMTP password. For example:method = smtpfrom = Joe Doe host = smtp.gmail.comport = 587username = JoeDoe@gmail.comtls = trueJust as in case of HTTP, you must set username, but must not set password here to use the extension, in other cases it will revert to the default behavior.UsageConfigure the repository as above, then just hg pull, hg push, etc. You should be asked for the password only once (per every username+remote_repository_url combination).Similarly, for email, configure as above and just hg email. Again, you will be asked for the password once (per every username+email_server_name+email_server_port).Implementation detailsThe extension is monkey-patching the mercurial passwordmgr class to replace the find_user_password method. Detailed order of operations is described in the comments inside the code.DevelopmentDevelopment is tracked on BitBucket, see http://bitbucket.org/Mekk/mercurial_keyring/Additional notesInformation about this extension is also available on Mercurial Wiki: http://mercurial.selenic.com/wiki/KeyringExtension Requirements: · Python · Mercurial
