TASKS

Expandgit merging conflicts after diverging
Revert local changes in a file to HEAD git checkout -- path/to/file.txt Discard ALL LOCAL COMMITS and get the (possibly diverged) remote instead git reset --hard origin/master

Expandgit create new branch on server, pull to client

# ON CENTRAL SERVER git checkout master # as needed; we are assuming that master is clean enough as a starting point git checkout -b mynewbranchy # HOWEVER, use this instead if you need a new "clean" repo and even master is dirty... # You need the rm because git "leaves your working folder intact". git checkout --orphan mynewbranchy git rm -rf . # ON CLIENT git pull git checkout -b mynewbranchy origin/mynewbranchy # if files are in the way from the previously checked-out branch, you can force it... git checkout -f -b mynewbranchy origin/mynewbranchy

Expandgit pull when untracked files are in the way
This will pull, forcing untracked files to be overwritten by newly tracked ones in the repo: git fetch --all git reset --hard origin/mymatchingbranch

Expandgit create new branch when untracked files are in the way
git checkout -b bj143 origin/bj143 git : error: The following untracked working tree files would be overwritten by checkout: (etc) TOTAL PURGE FIX (too much): git clean -d -fn "" -d dirs too -f force, required -x include ignored files (don't use this) -n dry run BEST FIX (just overwrite what is in the way): git checkout -f -b bj143 origin/bj143

Expandgit recreate repo
git clone ssh://m@thedigitalmachine.com/home/m/development/thedigitalage/ampache-with-hangthedj-module cd ampache-with-hangthedj-module git checkout -b daily_grind origin/daily_grind If you already have the daily_grind branches and just need to connect them: git branch -u origin/daily_grind daily_grind

Expandgit connect to origin after the fact
git remote add origin ssh:// m@bitpost.com/home/m/development/logs git fetch From ssh:// bitpost/home/m/development/logs * [new branch] daily_grind -> origin/daily_grind * [new branch] master -> origin/master git branch -u origin/daily_grind daily_grind git checkout master git branch -u origin/master master

CONFIGURATION

Expandgit visual difftool and mergetool setup

Meld is purdy, let's kick its tires. Hope it actually works... git config --global diff.tool meld git config --global merge.tool meld git config --global --add difftool.prompt false I used to set up kdiff3 manually, like this... (gross) LINUX - put this in ~/.gitconfig [diff] tool = kdiff3 [merge] tool = kdiff3 WINDOZE [difftool "kdiff3"] path = C:/Progra~1/KDiff3/kdiff3.exe trustExitCode = false [difftool] prompt = false [diff] tool = kdiff3 [mergetool "kdiff3"] path = C:/Progra~1/KDiff3/kdiff3.exe trustExitCode = false [mergetool] keepBackup = false [merge] tool = kdiff3 LINUX Before - What a ridiculous pita... copy this into .git/config... [difftool "kdiff3"] path = /usr/bin/kdiff3 trustExitCode = false [difftool] prompt = false [diff] tool = kdiff3 [mergetool "kdiff3"] path = /usr/bin/kdiff3 trustExitCode = false [mergetool] keepBackup = false [merge] tool = kdiff3

Expandgit convert to a bare repo

Start with a normal git repo via [git init]; add your files, get it all set up. Then do this: cd repo Now you can copy-paste this... mv .git .. && rm -fr * mv ../.git . mv .git/* . rmdir .git git config --bool core.bare true cd .. Don't copy/paste these, you need to change repo name... mv repo repo.git # rename it for clarity git clone repo.git # (optional, if you want a live repo on the server where you have the bare repo) Then you can clean up old branches like daily and daily_grind, as needed.

Expandgit convert bare to a mirror of remote (github, facebook, etc)

You need a bare mirror repo if you want to take someone else's repo and create your own bare to work from. If you did NOT specify --mirror when you first created the bare repo, you can convert to a mirror by adding these last two lines to config, underneath url: [remote "origin"] url = git@github.com:facebook/proxygen.git fetch = +refs/*:refs/* mirror = true Now you can fetch from the bare repo: git fetch

Expandgit create merge-to command
Add this handy alias command to all git repos' .config file... [alias] merge-to = "!gitmergeto() { export tmp_branch=`git branch | grep '* ' | tr -d '* '` && git checkout $1 && git merge $tmp_branch && git checkout $tmp_branch; unset tmp_branch; }; gitmergeto"

Expandgit fix github diverge from local bare repo following README.md edit

Yes editing the README.md file on github will FUCK UP your downstream bare repo if you meanwhile push to it before pulling. Fixing it is a PAIN in the ASS, you have to create a new local repo and pull github into that, pull in from your other local repo, push to github, pull to your bare... git clone git@github.com:moodboom/quick-http.git quick-http-with-readme-conflict git remote add local ../quick-http git fetch local git merge local/master # merge in changes, likely trivial git push # pushes back to github cd .. mv quick-http.git quick-http.git__gone-out-of-sync-fu-github-readme-editor git clone git@github.com:moodboom/quick-http.git --bare cp quick-http.git__gone-out-of-sync-fu-github-readme-editor/config quick-http.git/ And that MIGHT get you on your way... but I would no longer trust ANY of your local repos... This is a serious pita.

Expandgit windows configure notepad++ editor
git config --global core.editor "'C:/Program Files (x86)/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"

Expandgit fix push behavior - ONLY PUSH CURRENT doh
git config --global push.default current

Expandgit multiple upstreams

Use this to cause AUTOMATIC push/pull to a second origin: git remote set-url origin --push --add user1@repo1 git remote set-url origin --push --add user2@repo2 git remote -v show Leave out --push if you want to pull as well... but I'd be careful, it's better if code is changed in one client with this config, and then pushed to the multiple origins from there. Otherwise, things are GOING TO GET SYNCY-STINKY.
