2020-11-27 r/1936 fix(users/multi/home): fix tmux keybindings for tmux 3.1multi1-2/+2
The "swap-window" command swaps two windows, the 'source' and 'destination' window, exchanging the indices they occupy in the window list. In at least tmux 2.8 (which is what's in Debian Stable), if the window under focus is the source window, then focus follows that window (i.e. the focus changes to the current window's new index atomically with it being moved to that index). In more recent tmux versions, this is not the case, and the focus remains on the old index, so that the replacement window comes under focus. The former behaviour is still possible, but must be explicitly requested.

2020-11-27 r/1934 chore(tvix): avoid unnesscary rebuilds of protos and tvixAndreas Rammhold1-2/+26
For the build of tvix we can safely ignore all the files in src/protos as well as all the nix files in the root of the repository. By passing the input sources through builtins.filterSource we can make a per-file decision whether or not we want to copy it into the store (in other words: if we consider it relevant for the build). This enables much faster development on the actual build expression.

... still not that interesting, but at this point slightly divergent from the book: The book embraces mutability for interpreter state, initially for tracking whether an error condition has occured. I avoid this by instead defining an error type and collecting the error values, to be handled later on. Notes: So far nothing special, but this is just the beginning of the book. I like the style it is written in and it has pointed to some interesting resources, such as a 1965 paper titled "The Next 700 Languages".

2020-11-21 r/1892 fix(3p/cgit): Rename remaining 'sha1' references to 'oid'Vincent Ambo1-2/+2
This changed upstream & upstream-upstream, but was still used in our patches. Change-Id: Id33f868a4f188deb3348425276bc5b4c4b36aff9

2020-11-21 r/1890 merge(3p/git): Merge git subtree at v2.29.2Vincent Ambo1485-100645/+232762
This also bumps the stable nixpkgs to 20.09 as of 2020-11-21, because there is some breakage in the git build related to the netrc credentials helper which someone has taken care of in nixpkgs. The stable channel is not used for anything other than git, so this should be fine. Change-Id: I3575a19dab09e1e9556cf8231d717de9890484fb
2020-11-21 r/1889 merge(3p/absl): subtree merge of Abseil up to e19260fVincent Ambo854-5218/+11182
... notably, this includes Abseil's own StatusOr type, which conflicted with our implementation (that was taken from TensorFlow). Change-Id: Ie7d6764b64055caaeb8dc7b6b9d066291e6b538f
2020-11-21 r/1888 chore(tvix): Use StatusOr API available in Abseil's versionVincent Ambo4-8/+13
The Abseil version of `StatusOr` does not come with the status macros or the `Consume*` family of functions. This change modifies the existing code to use the common denominator of the API that is available between Abseil's own implementation of `StatusOr` and the one from Tensorflow that we are currently using.
