[git-users] how to check if my commit is propagated to later branchs?

[Jagadeesh N. Malakannavar]

Hello, I have branch structres something like this


/
   / rel-1
--//-  top of tree
  /
 /rel-2


I have made some commits on rel-1. After some months I branched out rel-2. 
How do I make sure that commits I made on rel-1 is in rel-2?
Just want to list out all missing commits on rel-2.
Thanks

That's a philosophical question rather than technical.

You used the word branched, and this means all the commits reachable
from the head rel-1 are also reachable from the head rel-2.
This means a simple (technical) answer to your question is yes, rel-2
contains all commits from rel-1, by definition.

If you implied, without spelling that, that rel-1 *moved* since the
point both branches diverged, then the answer is use git-log:

The call

  git log rel-1 ^rel-2

or, spelling the same the other way,

  git log rel-2..rel-1

would show the commits reachable from rel-1 but not reachable from
rel-2.
(To get better grasp on the idea of this read the section SPECIFYING
RANGES in the git-rev-parse manual page.)

Note that using this approach implies that rel-1 is periodically
re-merged (re-integrated) to rel-2 (or back).  If you, instead, just
cherry-picked a random commits from rel-1 to rel-2, they won't be
noticed by the `git log` (and `git merge-base`, which it uses)
machinery as it's only concerned with graphs of commits, and
cherry-picked commits do not contain any meta information about where
they came from, and do not mean joining of histories anyway.

Sorry, that should have been

   git log rel-2 ^rel-1
 
or
 
   git log rel-1..rel-2

instead because you'd want the reverse: to see all the commits reachable
from rel-2 but not reachable from rel-1 (and hence not present on it
-- even though this is technically not correct to describe it this way).
