Martin Ågren	4c399442f7	Doc: refer to the "commit-graph file" with dash The file processed by `git commit-graph` is referred to as the "commit-graph file", also with a dash. We have a few references to the "commit graph file", though, without the dash. These occur in git-commit-graph.txt as well as in Doc/technical/commit-graph.txt. Fix them. Do not change the references to the "commit graph" (without "... file") as a data structure.

Martin Ågren	4893d717a4	git-commit-graph.txt: refer to "commit-graph file" This document sometimes refers to the "commit-graph file" as just "the graph file". This saves a couple of words here and there at the risk of confusion. In particular, the documentation for `git commit-graph read` appears to suggest that there are indeed different types of graph files. Let's just write out the full name everywhere. The full name, by the way, is not the dash-less "commit graph file". Use the dashed form. (The next commit will fix the remaining few instances of the "commit graph file" in this document.)

Martin Ågren	a3a3ca002d	git-commit-graph.txt: fix bullet lists We have a couple of bullet items which span multiple lines, and where we have prefixed each line with a ``. (This might be the result of a text editor trying to help.) This results in each line being typeset as a separate bullet item. Drop the extra ``.

Derrick Stolee	59fb87701f	commit-graph: add '--reachable' option When writing commit-graph files, it can be convenient to ask for all reachable commits (starting at the ref set) in the resulting file. This is particularly helpful when writing to stdin is complicated, such as a future integration with 'git gc'.

Derrick Stolee	283e68c72f	commit-graph: add 'verify' subcommand If the commit-graph file becomes corrupt, we need a way to verify that its contents match the object database. In the manner of 'git fsck' we will implement a 'git commit-graph verify' subcommand to report all issues with the file. Add the 'verify' subcommand to the 'commit-graph' builtin and its documentation. The subcommand is currently a no-op except for loading the commit-graph into memory, which may trigger run-time errors that would be caught by normal use. Add a simple test that ensures the command returns a zero error code. If no commit-graph file exists, this is an acceptable state. Do not report any errors.

Derrick Stolee	7547b95b4f	commit-graph: implement "--append" option Teach git-commit-graph to add all commits from the existing commit-graph file to the file about to be written. This should be used when adding new commits without performing garbage collection. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	7 years ago
Derrick Stolee	3d5df01b5e	commit-graph: build graph from starting commits Teach git-commit-graph to read commits from stdin when the --stdin-commits flag is specified. Commits reachable from these commits are added to the graph. This is a much faster way to construct the graph than inspecting all packed objects, but is restricted to known tips. For the Linux repository, 700,000+ commits were added to the graph file starting from 'master' in 7-9 seconds, depending on the number of packfiles in the repo (1, 24, or 120).
