chore(3p/git): Unvendor git and track patches instead r/2903
This was vendored a long time ago under the expectation that keeping it in sync with cgit would be easier this way, but it has proven not to be a big issue. On the other hand, a vendored copy of git is an annoying maintenance burden. It is much easier to rebase the single (dottime) patch that we have. This removes the vendored copy of git and instead passes the git source code to cgit via `pkgs.srcOnly`, which includes the applied patch so that cgit can continue rendering dottime.

A big part of the job of this - class is to figure out these things, and to make sure that new - commits are only detailed once even if they were added to multiple - references. - - The first step is to determine the "other" references--those - unaffected by the current push. They are computed by listing all - references then removing any affected by this push. The results - are stored in Push._other_ref_sha1s. - - The commits contained in the repository before this push were - - git rev-list other1 other2 other3 ... change1.old change2.old ... - - Where "changeN.old" is the old value of one of the references - affected by this push. - - The commits contained in the repository after this push are - - git rev-list other1 other2 other3 ... change1.new change2.new ... - - The commits added by this push are the difference between these - two sets, which can be written - - git rev-list \ - ^other1 ^other2 ... \ - ^change1.old ^change2.old ... \ - change1.new change2.new ... - - The commits removed by this push can be computed by - - git rev-list \ - ^other1 ^other2 ... \ - ^change1.new ^change2.new ... \ - change1.old change2.old ... - - The last point is that it is possible that other pushes are - occurring simultaneously to this one, so reference values can - change at any time. It is impossible to eliminate all race - conditions, but we reduce the window of time during which problems - can occur by translating reference names to SHA1s as soon as - possible and working with SHA1s thereafter (because SHA1s are - immutable).""" - - # A map {(changeclass, changetype): integer} specifying the order - # that reference changes will be processed if multiple reference - # changes are included in a single push.
