* global numcopies settingGravatar Joey Hess2014-01-20
| | | | | | | | | | | | | | | | | | | | | | | * numcopies: New command, sets global numcopies value that is seen by all clones of a repository. * The annex.numcopies git config setting is deprecated. Once the numcopies command is used to set the global number of copies, any annex.numcopies git configs will be ignored. * assistant: Make the prefs page set the global numcopies. This global numcopies setting is needed to let preferred content expressions operate on numcopies. It's also convenient, because typically if you want git-annex to preserve N copies of files in a repo, you want it to do that no matter which repo it's running in. Making it global avoids needing to warn the user about gotchas involving inconsistent annex.numcopies settings. (See changes to doc/numcopies.mdwn.) Added a new variety of git-annex branch log file, that holds only 1 value. Will probably be useful for other stuff later. This commit was sponsored by Nicolas Pouillard.
* add remote state logsGravatar Joey Hess2014-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | This allows a remote to store a piece of arbitrary state associated with a key. This is needed to support Tahoe, where the file-cap is calculated from the data stored in it, and used to retrieve a key later. Glacier also would be much improved by using this. GETSTATE and SETSTATE are added to the external special remote protocol. Note that the state is left as-is even when a key is removed from a remote. It's up to the remote to decide when it wants to clear the state. The remote state log, $KEY.log.rmt, is a UUID-based log. However, rather than using the old UUID-based log format, I created a new variant of that format. The new varient is more space efficient (since it lacks the "timestamp=" hack, and easier to parse (and the parser doesn't mess with whitespace in the value), and avoids compatability cruft in the old one. This seemed worth cleaning up for these new files, since there could be a lot of them, while before UUID-based logs were only used for a few log files at the top of the git-annex branch. The transition code has also been updated to handle these new UUID-based logs. This commit was sponsored by Daniel Hofer.

* refactor git-annex branch log filename code into central locationGravatar Joey Hess2013-08-29
Having one module that knows about all the filenames used on the branch allows working back from an arbitrary filename to enough information about it to implement dropping dead remotes and doing other log file compacting as part of a forget transition.
