Clone large svn repository

git svn clone -r1:HEAD http://my-project.googlecode.com/svn/ --authors-file=users.txt --no-metadata -s my_project
git svn fetch -r1:HEAD --authors-file=users.txt

Clone and auto checkout

git clone --branch

Сlone a specific branch

git clone --branch --single-branch

Apply range of commits

git cherry-pick <start hash of commit - 1>..<end hash commit>

Patch

git diff (-binary) <> > <name>.patch
git format-patch <>

git apply <name>.patch

Stash the changes

git stash
git stash apply
git stash --save "massage_text"

git reset --hard commit_hash

Does not touch the index file or the working tree at all

git reset --soft commit_hash

Resets the index but not the working tree. Default

git reset --mixed commit_hash

Resets using index

git reflog
git reset HEAD@{<index>}

Show log with graph

git log --decorate --graph --branches --oneline
git log --all --decorate --graph --oneline

Install

git clone --mirror git://example.com/some-big-repo.git

Clean the repository

java -jar bfg.jar --strip-blobs-bigger-than 100M some-big-repo.git

Replace the passwords

bfg --replace-text passwords.txt  my-repo.git

Remove the files and folders

bfg --delete-folders .git --delete-files .git  --no-blob-protection  my-repo.git

1. Create commits authors file

   svn log --xml | grep author | sort -u | perl -pe 's/.*>(.*?)<.*/$1 = /' > users.txt
   

2. Then allow the record to the form

   krasnovov = Krasnov Oleg Viktorovich <krasnovov@example.com>
   

3. Cone repository

   • git svn clone http://my-project.googlecode.com/svn/ --authors-file=users.txt --no-metadata -s my_project
     

   • If repository so large and get timeout, use host with fast file system

   • For contine, execute command

     git svn fetch --authors-file=../users.txt
     

   • To clone to a specific revision use -rXXX:HEAD parameter

     git svn clone -rXXX:HEAD http://my-project.googlecode.com/svn/ --authors-file=users.txt --no-metadata -s my_project
     git svn fetch -rXXX:HEAD --authors-file=../users.txt
     

4. Create .gitignore file

   git svn show-ignore > .gitignore
   

5. Create backup

6. Convert branches and tags

   for t in $(git for-each-ref --format='%(refname:short)' refs/remotes/tags); do git tag ${t/tags\//} $t && git branch -D -r $t; done
   for b in $(git for-each-ref --format='%(refname:short)' refs/remotes); do git branch $b refs/remotes/$b && git branch -D -r $b; done
   

7. Remove tag and branch with suffix @xxx

   for p in $(git for-each-ref --format='%(refname:short)' | grep @); do git branch -D $p; done
   for p in $(git for-each-ref --format='%(refname:short)' | grep @); do git tag -d $p; done
   

8. Push local repository to remote

   git branch -d trunk
   git remote add origin git@my-git-server:myrepository.git
   git push origin --all
   git push origin --tags
   

To synchronize the changes made in svn, restore from backup step №5 and repeat the steps.

git svn fetch --authors-file=../users.txt

Filename too long

git config --global core.longpaths true

Illegal instruction

git config --global core.fscache true
