git svn branch results in Authentication failed - git-svn

I'm trying to do all of my branching and merging via git-svn, however I'm hung up on the branching in subversion.
Our admin tells me that I have full read/write permissions on the repo, and I CAN fetch the latest code.
For a test, I deleted my ~/.subversion/svn.simple directory and ran this.
04:13 pm [214423L] C:\Dev\MyFooApp.Bar [master]
$ git svn fetch
Authentication realm: <https://code:443> VisualSVN Server
Password for 'cflorell': {my password}
04:14 pm [214423L] C:\Dev\MyFooApp.Bar [master]
$ git svn fetch
04:14 pm [214423L] C:\Dev\MyFooApp.Bar [master]
$
Also, if I clone the repo using Tortoise, and then create a branch using svn it appears to work.
04:43 pm [214423L] C:\Dev\MyFooApp.Bar
$ svn copy https://code/svn/MyFooApp.Bar/trunk https://code/svn/MyFooApp.Bar/branches/test-branch -m "test branch"
Committing transaction...
Committed revision 93.
But upon trying to create a branch using git-svn, it still says my auth is invalid.
04:14 pm [214423L] C:\Dev\MyFooApp.Bar [master]
$ git svn branch develop
Copying https://code/svn/MyFooApp.Bar/trunk at r92 to https://code/svn/MyFooApp.Bar/branches/develop...

My config file is I believe correct.
[core]
repositoryformatversion = 0
filemode = false
bare = false
logallrefupdates = true
symlinks = false
ignorecase = true
hideDotFiles = dotGitOnly

url = https://code/svn/MyFooApp.Bar
fetch = trunk:refs/remotes/svn/trunk
branches = branches/*:refs/remotes/svn/*
tags = tags/*:refs/remotes/svn/tags/*
Where might I be going wrong with all of this?

Note that more than a year later (March 2017), Git 2.13+ (Q2 2017) should avoid that git svn authentication issue.
See commit e0688e9 (06 Mar 2017) by Hiroshi Shirosaki (shirosaki).
It recognizes that authentication fails with svn branch while svn rebase and svn dcommit work fine without authentication failures.
$ git svn branch v7_3

Authentication failed at
C:\Program Files\Git\mingw64/libexec/git-core\git-svn line 1200.
We add auth configuration to SVN::Client->new() to fix the issue.

So it looks like there is a conflict between Tortoise SVN and git-svn, I'm not sure if this exists in other versions of SVN or not but I uninstalled Tortoise SVN and was then able to branch using git svn branch branchName
C:\Files\Source\Repos\applications\core\App01>git svn branch branchName

Going to try some other SVN Browser for the time being and see if that also has an issue.

According to https://gist.github.com/kasparsd/3749872/563011118e33900b3a0ca89ec37f3c99be8e9c49 , there's no way to authenticate using git svn tag (used to work, but stopped working).
Instead, use svn directly to submit a tag:
svn cp <trunk-ul> <tag-url> -m "creating tag x.x"
It will ask to store your password in plain text though.

How to solve merge conflict in a approved review in gerrit?

I made a change in gerrit which was code reviewed and after 7 revisions approved. But, now it cannot be merged and trying to rebase in gerrit website is not working due to merge conflict. How can I resolve this merge conflict and merge the same approved change and not create a new one.
(Full steps from cloning the repo would be appreciated.)
1) Clone the Gerrit repository
git clone https://USER#GERRIT-SERVER/a/REPO-FULL-PATHNAME
2) Go to the change page on Gerrit and copy the checkout patch command
git fetch https://USER#GERRIT-SERVER/a/REPO-FULL-PATHNAME refs/changes/XX/YYYYY/Z && git checkout FETCH_HEAD
3) Rebase the change
git rebase origin/BRANCH
4) Solve the conflicts
git mergetool
5) Continue the rebase
git rebase --continue
Repeat the steps 4 and 5 until the end of conflicts
git commit --amend
Note: Keep the same Change-Id
6) Send the new patchset to Gerrit
git push origin HEAD:refs/for/BRANCH
The accepted solution works but I personally disagree with this workflow. It is unnecessarily cumbersome.
I prefer a workflow with exactly one merge and therefore less steps.
Clone the Gerrit repository if not already available
git clone https://[USER]#[GERRIT-SERVER]/a/[REPO-FULL-PATHNAME]
Checkout the Gerrit patch
git fetch https://[USER]#[GERRIT-SERVER]/a/[REPO-FULL-PATHNAME] refs/changes/46/12346/N && git checkout FETCH_HEAD
Soft-reset the change and stash it
git reset --soft HEAD~1 && git stash
Checkout branch or the Gerrit patch you want to rebase onto
git checkout origin/BRANCH
# or fetch other Gerrit patch:
# git fetch https://[USER]#[GERRIT-SERVER]/a/[REPO-FULL-PATHNAME] refs/changes/45/12345/N && git checkout FETCH_HEAD
Unstash the previously stashed changes
git stash pop
Solve the conflicts with your favourite 3-way merge tool.
Commit the merged changes - NOT (!!) amend them - and use the same Change-Id from the merged patch in the message:
git commit -am "[COMMIT-MESSAGE]\
\
Change-Id: [FORMER-CHANGE-ID]"
Send the new patchset to Gerrit
git push origin HEAD:refs/for/BRANCH
Done. One merge!
I additionally use the gitreview tool. That makes it extra easy. Steps 2, 3, 4 and 5 then can be chained.
git review -d 12346 && git reset --soft HEAD~1 && git stash && git review -d 12345 && git stash pop

Create a svn branch from git when directory structure differs

I created a local git copy of an svn repo with the following commands:
$ git svn init svn://host/path/to/repo/PROJECT/trunk workingcopy
$ cd workingcopy
$ git svn fetch
Now I'm trying to create an svn branch without success:
$ git svn branch -n mybranch -m "Branch for my things"
Multiple branch paths defined for Subversion repository.
You must specify where you want to create the branch with the --destination argument
In .git/config I do not have any entries under [svn-remote "svn"] as suggested in this answer. I tried adding branches = branches/*:refs/* but this tries to create the branch under the trunk:
Copying svn://host/path/to/repo/PROJECT/trunk at r6684 to svn://host/path/to/repo/PROJECT/trunk/branches/mybranch
What do I need to do to create a branch in the correct location?
Okay, so I changed .git/config from:
[svn-remote "svn"]
url = svn://host/path/to/repo/PROJECT/trunk
fetch = trunk:refs/remotes/git-svn
to:
[svn-remote "svn"]
url = svn://host/path/to/repo/PROJECT
fetch = trunk:refs/remotes/git-svn
branches = branches/*:refs/remotes/*
This worked, but I ran into problems trying to access the branch from a git repo on another machine. In the end, I pushed my changes to svn, then deleted my local git repo and cloned it properly this time:
$ git svn clone --standard-layout --prefix=svn/ svn://host/path/to/repo/PROJECT

git-svn: how to change the svn username on dcommit?

I cloned a SVN repository into a git repository using git svn clone. At that point in time, I did not have a username at that site and hence didn't use the --username option of clone. As I can now commit to the SVN repository with my new username, I would like to add that username. Without it, dcommit simply fails:
% LANG=C git svn dcommit
Committing to <THE URL> ...
RA layer request failed: Server sent unexpected return value (405 Method Not Allowed) in response to MKACTIVITY request for '/svn/!svn/act/0ceca4c5-f7b4-4432-94be-0485559a6040' at /usr/lib/git-core/git-svn line 945.
Is there a way to tell git about a new username? The git-svn manual doesn't seem to help: adding a username is only allowed on init and branch. I don't know how git works with SVN internally, but I guess there should be a way to add a username afterwards.
Note that I am using SVN over http.
You can specify the username in the dcommit command, e.g.
git svn dcommit --username=isapir
I think you can use this procedure (from the git svn manpage) to create a clone of your existing svn repository, but change the git svn init step so that it specifies a username. Your new git-svn repository will then have a username.
# Clone locally - make sure the refs/remotes/ space matches the server
mkdir project
cd project
git init
git remote add origin server:/pub/project
git config --replace-all remote.origin.fetch '+refs/remotes/*:refs/remotes/*'
git fetch
# Prevent fetch/pull from remote git server in the future,
# we only want to use git svn for future updates
git config --remove-section remote.origin
# Create a local branch from one of the branches just fetched
git checkout -b master FETCH_HEAD
# Initialize 'git svn' locally (be sure to use the same URL and -T/-b/-t options as were used on server)
git svn init --username my_new_name http://svn.example.com/project
# Pull the latest changes from Subversion
git svn rebase
Note that if you specify a username, you would not be able to dcommit a merge commit, not before Git 2.16.x/2.17 (Q1 2018).
That is because "git svn dcommit" did not take into account the fact that a
svn+ssh:// URL with a username# (typically used for pushing) refers
to the same SVN repository without the username# and failed when
svn.pushmergeinfo option is set.
See commit 8aaed89 (15 Sep 2017) by Jason Merrill (jwmerrill).
(Merged by Jason Merrill -- jwmerrill -- in commit 8aaed89, 17 Sep 2017)
git-svn: fix svn.pushmergeinfo handling of svn+ssh usernames.
Previously, svn dcommit of a merge with svn.pushmergeinfo set would
get error messages like
merge parent <X> for <Y> is on branch svn+ssh://gcc.gnu.org/svn/gcc/trunk,
which is not under the git-svn root svn+ssh://jason#gcc.gnu.org/svn/gcc!"
So, let's call remove_username (as we do for svn info) before comparing
rooturl to branchurl.

How can I do a git svn reset to HEAD revision without specifying the revision number?

How can I do a git svn reset to HEAD revision without specifying the revision number?
It sounds like what you want is not a git svn reset but a simple git checkout. I'm not sure what you mean when you say you reverted to an older revision, but it may have been something like
$ git log
# scan through the log looking for a particular commit.
# You find it and its SHA1 is abc123...
$ git checkout abc123
You are now in 'detached HEAD' state blah blah blah...
Now, HEAD (in your git repository) refers to the commit with SHA1 abc123, whereas HEAD (in the central SVN repository) refers to the newest commit on the SVN repository. If you have things set up in a fairly typical way, then you can just do git checkout master and then git svn rebase and you're back to normal working conditions.

How to commit a Git repo to an empty repo SVN server?

I have setup an empty svn on a server and I have been working on locally making commits along the way. Now I wish to commit my repo to an svn server. For this I tried:
git-svn checkout http://remote.svn.server.com
git-svn dcommit
Git complains that:
Use of uninitialized value in concatenation (.) or string at /usr/bin/git-svn line 411.
Committing to ...
Unable to determine upstream SVN information from HEAD history
Since I started on my local computer first, and the repo online is empty, I can't find any info on how to make this work.
I needed something like this recently and the process is relatively straightforward.
There's good tutorial by Brandon Dimcheff, "Commit a linear git history to subversion" (replaces old broken link), which these steps are based on.
As of Git version 1.6.3 these are the steps:
$ svnadmin create svn_repository
$ svn mkdir -m "Initial setup" file:///full/path/to/svn_repository/trunk
$ mkdir gitrepo && cd gitrepo
$ git init
$ echo 'Hello from Git' > file.txt
$ git add file.txt
$ git commit -m "Hello from Git"
$ git svn init --trunk=trunk file:///full/path/to/svn_repository/
$ git svn fetch
$ git branch -a # Lists remotes/trunk
$ git rebase --onto remotes/trunk --root master
# => Applying: Hello from Git etc.
$ git svn dcommit
# => Committing to ... Committed r2 ... etc
You can do a svn checkout of svn_repository now and see your Git repo.
Here is what I would do:
git-svn clone http://remote.svn.server.com otherdir
Then in other dir pull the changes locally from your previous dir. Then you should have a git repo that is "connected" via git-svn and you should be able to use dcommit on it.
This might also be a useful read.
