GIT Repository

Setup

You need to setup your name and email

git config --global user.name  "Your Username"
git config --global user.email foo@soe.ucsc.edu

Checkout/clone once ESESC

git clone ssh://mada0.cse.ucsc.edu/mada/server/git/esesc

Checkout/clone once MTHD

git clone ssh://mada0.cse.ucsc.edu/mada/server/git/mthd

Checkout/clone once SCOORE

git clone ssh://mada0.cse.ucsc.edu/mada/server/git/scoore.git

Checkout/clone once SYNOS (the public branch of SCOORE)

git clone git://mada0.cse.ucsc.edu/synos.git

Operation

To see changes from local re-vision compared to main repo... similar to svn status

git status

Every day synchronize with other people modifications

git pull

Whenever you perform a task commit the changes

git commit -a

Remember that a commit does not make the changes visible. Do frequent pushes to the server

git push

To add/rename files uses the git command

git mv foo foo2
git add foo.cpp

If you did something in the local repository that it is wrong, and you want to revert the edits (equivalent to svn revert -R .)

git reset --hard HEAD

To see the current changes still not committed against the last commit (HEAD)

git diff HEAD

To see the current changes against the last against the previous to last commit (HEAD^)

git diff HEAD^

QEMU Inclusion in ESESC

ESESC includes code from the QEMU git repository. This is merged into the ESESC repository using the subtree merge strategy.

The initial steps to merge the qemu git repository were:

git remote add -f qemu-mainline git://git.savannah.nongnu.org/qemu.git
git merge -s ours --no-commit qemu-mainline/master
git read-tree --prefix=emul/qemu/ -u qemu-mainline/master
git commit -m "adding qemu-mainline code"

Getting updates from QEMU git is done with

git pull -s subtree qemu-mainline master

Since QEMU is already included in ESESC the initial configuration steps are not all needed for new repository clones. The only step needed is add the remote ref:

git remote add -f qemu-mainline git://git.savannah.nongnu.org/qemu.git

SYNOS vs SCOORE

SYNOS repository is the public version of SCOORE. SCOORE is regularly updated with patches sent to SYNOS, and once the code is stable, code from SCOORE is updated in SYNOS.

Merge Code from SYNOS to SCOORE

First, you should add the SYNOS as a remote branch in your SCOORE local repository

git remote add ucsc git://mada0.cse.ucsc.edu/synos.git
git fetch ucsc

Second, you should create a branch in the local SCOORE repository that tracks the remote SYNOS repository

git checkout --track -b ucsc remotes/ucsc/master

Third, you should merge/import all the SYNOS edits to the latest SCOORE master branch

git checkout master
git merge ucsc
git config push.default matching
git push

Merge Code from SCOORE to SYNOS

If you do not have write commits to synos, create a patch and send it to the MASC group

git diff ucsc/master ./scripts/ ./memcell ./docs ./storage >../patch

Make sure that you include only the files that you want to send. E.g:

git diff ucsc/master -- memcell >patch.memcell
