Git log print commits between a revision range (inclusive)

Git log print commits between a revision range (inclusive)

[wuzhouhui]

Hi,

I want to know how to display logs between a revision range (both
start and end are inclusive). I searched it and only found[1],
which doesn't resolve my problem completely, because

  git log <older hash>..<newer hash>

doesn't contains the log of <older hash>. So, how to display
logs between a revision range that both start and end are
inclusive?

Please CC me, thanks.

 $ git log maint --not v2.20.0^@

gives you commits that are reachable from (i.e. ancestors of) maint,
excluding those that are reachable from the set of commits denoted
by v2.20.0^@.

v2.20.0^@ is how you spell the set of commits that are parents of
the commit v2.20.0.

If your "range" is simple and "old" is a single-parent commit,

 $ git log <old>~1..<new>

is equivalent, because <old>~1 (i.e. the first parent of commit
<old>) would be the same as <old>^@ for a single-parent commit, and
because the short-hand "git log A..B" is the same as the long-hand
"git log B --not A".

As Junio mentioned, "A..B" means all commits reachable from B except those
reachable from A. Understanding this is just a way to say "B --not A" is
important to know you can take advantage of:

`--boundary`
    Output excluded boundary commits. Boundary commits are prefixed with -.

In other words, git log --boundary <older hash>..<newer hash> should give you
exactly what you asked with the small caveat it marks excluded commits
differently.

You are correct, but only when dealing with a single strand of
pearls.  If the history leading to <newer> is bushy with merges, the
above will give _far_ more than what was requested.  The fork points
of the side branches that got merged during <old>..<new> will also
be shown, in addition to the <old>.
