So here it is. Note that the version of git on my $PATH is usually the one from the proposed updates branch, so some of the commands I use in the following text may not work for you unless you also have built "pu" one yourself. I am planning to finish updating, testing and documenting what's in the current proposed updates branch, and have most of them graduate to the master branch over the weekend. I am aiming for doing the 0.99.5 on Wednesday next week. ------------ I have the following heads all the time in my private repository: master - the one to be pushed to public "master" branch pu - master plus various proposed changes rc - master plus minimum release engineering ko-master - a copy of public "master" branch head ko-rc - a copy of public "rc" branch head My GIT day always starts with this command: $ git fetch ko I have this in .git/remotes/ko: $ cat .git/remotes/ko URL: master.kernel.org:/pub/scm/git/git.git/ Pull: master:ko-master rc:ko-rc Push: master pu rc The Pull: line gives me the default set of <refspec>s to give to the "git fetch" command. I slurp "master" and "rc" heads from the public repository at master.kernel.org, and fast-forward my ko-master and ko-rc branches with them. I do not touch these two branches in any way other than this "git fetch" fast forwarding. I have a few "topic branches" in addition to the above; they change from time to time. Recently I've been looking at multi-head fetches, and that work is done in "mhf" branch. There also is a catch-all topic called "misc". I started them like this: $ git branch mhf master $ git branch misc master The first thing I do during my GIT day is to process the patches I received via e-mail. I store them one topic per file in my working tree, like this: $ ls +*.txt +js-glossary.txt +mc-mailinfo.txt Depending on the quality of the patch, seriousness of the bug they fix, and the area of the code they touch, they either go directly to "master", "misc", or sent back to the sender, but the last one, luckily for me, rarely happens: $ git checkout master $ git applymbox -q ./+js-glossary.txt .git/info/signoff $ git checkout misc $ git applymbox -q ./+mc-mailinfo.txt please The last parameter to the applymbox command is the name of a file that has my signoff message. The latest applymbox in the "pu" branch has a bit more useful extension to do the same thing as what "git commit" does. At this point, I may push out the "master" branch (and nothing else), like this: $ git push ko master This pushes only "master", ignoring the default <refspec>s defined in the .git/remotes/ko file you saw earlier. Once I am done with the outside patches, I go back to where I left off the previous day: $ git checkout mhf And I check where my head is relative to the master: $ git show-branches master mhf ! [master] Yet another tweak * [mhf] Make git-fetch-script a bit more chatty. + Yet another tweak + Another tweak in Makefile + Make git-fetch-script a bit more chatty. + Update git-ls-remote-script + ... + Start adding the $GIT_DIR/remotes/ support. ++ [PATCH] Allow file removal when "git commit --all" is used. The output from show-branches is a poor-man's gitk. The named branches are shown, and '+' sign in each column shows whether the commit is contained in each branch, and the output stops where all branches converge, or you hit ^C ;-). If the mhf branch is way behind, I may choose to first rebase it, to clean up my history: $ git rebase master $ git show-branches master mhf ! [master] Yet another tweak * [mhf] Make git-fetch-script a bit more chatty. + Make git-fetch-script a bit more chatty. + Update git-ls-remote-script + ... + Start adding the $GIT_DIR/remotes/ support. ++ Yet another tweak I keep working in my topic branches. I may make some other changes in "misc" topic branch. It's a simple cycle of: $ edit-and-test $ git commit -s -a -v Eventually I get to a good point where it makes sense to push things to the public repository. $ git show-branches master mhf misc ! [master] Yet another tweak * [mhf] Make git-fetch-script a bit more chatty. ! [misc] Add hooks to tools/git-applypatch. + Make git-fetch-script a bit more chatty. + Update git-ls-remote-script + ... + Start adding the $GIT_DIR/remotes/ support. ++ Yet another tweak ++ Another tweak in Makefile + Add hooks to tools/git-applypatch. + Add commit hook and make the verification customizable. +++ [PATCH] Allow file removal when "git commit --all" is used. As you may have noticed, my topic branches are private and not pushed to the public repository. Instead, I make a grand total merge of them into "pu". The proposed update branch is always rewound and made from the head of the master: $ git checkout pu $ git reset master This checks out the head of "pu" branch, and then resets the index file to match "master" and updates .git/refs/heads/pu. What it does _not_ do is to update my working tree to match the index file. Linus recommends to do "git checkout -f" at this point, but I typically do this instead: $ git diff -R -p | git apply Note. This is an embarrassingly expensive way; the only thing it buys me over "git checkout -f" is that it removes the files that were introduced in "pu" branch that did not exist in the "master" head. I have to come up with a not so expensive way to do this. Then before doing the grand total merge, check again where those heads are: $ git show-branches master mhf misc pu ! [master] Yet another tweak ! [mhf] Make git-fetch-script a bit more chatty. ! [misc] Add hooks to tools/git-applypatch. * [pu] Yet another tweak + Make git-fetch-script a bit more chatty. + Update git-ls-remote-script + ... + Start adding the $GIT_DIR/remotes/ support. ++ + Yet another tweak ++ + Another tweak in Makefile + Add hooks to tools/git-applypatch. + Add commit hook and make the verification customizable. ++++ [PATCH] Allow file removal when "git commit --all" is used. Notice that I did not rebase "misc" above, but that is OK. What I want to do here is to make new "pu" an Octopus over "master", merging in all my topic branches (currently "mhf" and "misc"). $ git fetch . mhf misc Packing 0 objects Unpacking 0 objects * committish: a101f32...e5580 refs/heads/mhf from . * committish: 4426ac7...0c5bc refs/heads/misc from . This fetches two heads from the current repository (!). The only reason I do it is that the tentative implementation of "git octopus" always reads from $GIT_DIR/FETCH_HEAD, and "git fetch" is the way to populate that file. $ git octopus Removing git-parse-remote Removing git-parse-remote Committed octopus merge fe1899156bffa4be6722b2ca0b74ff17b76523da Makefile | 3 - git-commit-script | 75 +++++------------- ... tools/git-applypatch | 87 ++++++++++++++++---- 15 files changed, 551 insertions(+), 224 deletions(-) This makes an Octopus out of the master and other two topic branches. I can make sure that resulting "pu" contains all the necessary commits from the branches involved: $ git show-branches master mhf misc pu ! [master] Yet another tweak ! [mhf] Make git-fetch-script a bit more chatty. ! [misc] Add hooks to tools/git-applypatch. * [pu] Octopus merge of the following: + Octopus merge of the following: + + Make git-fetch-script a bit more chatty. + + Update git-ls-remote-script + + ... + + Start adding the $GIT_DIR/remotes/ support. ++ + Yet another tweak ++ + Another tweak in Makefile ++ Add hooks to tools/git-applypatch. ++ Add commit hook and make the verification customizable. ++++ [PATCH] Allow file removal when "git commit --all" is used. And things are now ready to be pushed out. First I sanity check the differences between ko-master and master (the earlier "git fetch ko" was done only for this step): $ git show-branches master ko-master ... and then run "git push": $ git push ko This will push "master" and "rc" but would fail to push "pu", because that is rebased and not based on what is on the public repository. So I push once more, this time with --force, like this: $ git push --force ko pu This pushes only "pu", ignoring the default <refspec>s defined in the .git/remotes/ko file you saw earlier. After that, I go back to reading the mail and wait until the kernel.org mirror network catches up. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
