Using TortoiseSVN, I need to take changes I've done in a branch and then merge them with trunk.
I am the only developer on this project, so I know trunk hasn't changed. I am learning SVN so that eventually my team can use it.
Basically, I want my trunk to look exactly like the branch.
In pre-svn world, I would just copy the files in my branch folder, delete the files in the trunk folder, and then copy branch into trunk.
In TortoiseSVN, I've tried Reintegrate a branch, Merge a range of revisions, and Merge two different trees. Nothing seems to actually change trunk. I've also tried branching on top of the trunk. This gives me an error, saying that the trunk already exists.
In your case:
Switch the working copy to the trunk (SVN Switch)
Merge the branch into the working copy (SVN Merge)
Make sure everything still compiles and works
Commit the working copy (the trunk)
Consider killing the branch
In a team environment I would suggest that you first merge the latest modifications from the trunk in your branch, make sure that everything compiles and works, then do the above steps (which will be trivial since you've already tested the changes).
Update
In step 5, I mention killing the branch. That's because once a branch from a feature is in the trunk, it should be considered as part of the trunk. In that case the branch should be killed so that no one keeps working on it. If major modifications are needed for that feature, you should create a new branch for that.
The only branches that I don't kill are maintenance and release branches, unless a particular release is no longer supported.
No matter what, you always have access to every revision so killing a branch is only used to prevent other developers from developing on a dead branch.
I think in TortoiseSVN 1.8.5, Merge | Merge two different trees should work. When you merge a branch/tag back to trunk, the trick is that the From URL is the trunk and the To is the tag/branch. Weird but true.
Source: Merging
For directories that not in your working copy but are in the tag/branch you may get conflict errors. Just accept the conflict and redo the merge.
First switch your working copy to the trunk.
Then do a merge range of revisions, from the branch to trunk.
Once this dialog is complete the differences will be pending changes in your working copy of trunk. You'll need to commit them just as if you manually made the changes on your working copy.
In my usage, its more typical to keep trunk running and spin branches off at the times of builds. So then the only merge I ever need to do is to get a bug fix out of trunk and put it on the latest build branch and re-release that branch. The easiest way for me to do this, since as you have found merging is clumsy at best. Is to keep the latest branch and the trunk checked out to my machine, and to quite literally copy the files from trunk to branch and check both in.
I am using TortoiseSVN 1.9.3, Build 27038.
Follow below steps in order to merge branch into trunk.
1) Right click on trunk working copy and select the below option.
2) In case of Branch Merging into trunk select option second as shown below and click next
3) In the From: field enter the full folder URL of the trunk. This may sound wrong, but remember that the trunk is the start point to which you want to add the branch changes.
In the To: field enter the full folder URL of the feature branch.
4) Click next and do the test merge
5) If test merge is successful then click on Merge button.
6) Once merge is successful then commit the changes on trunk.

I had a functional version of code which I was trying to commit to my local branch,
However, previously I tried to make some changes that were not accepted on that branch. So I reverted back to a previous commit.
So I was working out of a commit that was 2nd to last in the branch
Then I made some more changes, tested the program, and tried to commit again,
Then tortoise svn forced me to update, I assumed it was updating the files for the current revision I was on. But no, unfortunately, it Updated the files to the Latest commit, which I did not want, then it tried to merge my changes on top of that, so I had changes that I wanted on top of changes that I didn't want merged together!
Can I undo this and keep my changes that I just made that I wanted to commit? What did I forget to do, was I supposed to stash all of the newer commits?
Right click on file you will have option replace with choose the local history. Select the local version you want to keep.
Its done. You are good to go :)
I have used svn for a while but recently a couple teams were added to the project. One of the teams made a new branch and has asked me to check some of their changes. I went to the directory, right click, svn->switch and chose the new branch. I went in and tried to echo something to the page I was on to see if I was working in the new branch and I wasn't. This is a little beyond what I do but with the project getting so big I need to learn this.
Based on that, my question..is there something more to this that I am not doing? After switching the working copy to this new branch how do I work on it?
The difference between checkout and switch might be adding to the confusion. I think that in your case it would be simpler to just check out the branch to a different folder since you're just doing review and it may be the most straightforward way to proceed regardless.
See this section from the Tortoise docs:
To Checkout or to Switch...
...that is (not really) the question. While a checkout downloads
everything from the desired branch in the repository to your working
directory, TortoiseSVN → Switch... only transfers the changed data to
your working copy. Good for the network load, good for your patience.
:-)
To be able to work with your freshly generated branch or tag you have
several ways to handle it. You can:
TortoiseSVN → Checkout to make a fresh checkout in an empty folder.
You can check out to any location on your local disk and you can
create as many working copies from your repository as you like.
Switch your current working copy to the newly created copy in the
repository. Again select the top level folder of your project and use
TortoiseSVN → Switch... from the context menu.
In the next dialog enter the URL of the branch you just created.
Select the Head Revision radio button and click on OK. Your working
copy is switched to the new branch/tag.
Switch works just like Update in that it never discards your local
changes. Any changes you have made to your working copy which have not
yet been committed will be merged when you do the Switch. If you do
not want this to happen then you must either commit the changes before
switching, or revert your working copy to an already-committed
revision (typically HEAD).
If you want to work on trunk and branch, but don't want the expense of
a fresh checkout, you can use Windows Explorer to make a copy of your
trunk checkout in another folder, then TortoiseSVN → Switch... that
copy to your new branch.
In the regular "Properties" dialogue (right click on Windows explorer) you have a "Subversion" tab that will tell you what URL the file or directory points to. Use that to verify that you actually switched to the correct branch.
It's also worth nothing that any non-committed local changes will still be in your working copy.
There might be a misconception about svn switch :
At first I thought that the existence of a switch command would imply that there were a "current" or a "selected" working copy for the proper functioning of SVN. Like I'm currently working on trunk, then I'm working on a branch B, hence "switching" from a working copy to another. The truth is : there is no such thing as a current working copy ! There are just many local working copies : one for the trunk, one for a branch another for a tag and so on. But none would be "implicitly selected".
As Paul Sasik quotes : switch would allow, for instance, to have only one working copy of say, the trunk, and then, merging that local working copy with a targeted branch or tag from the remote repository. switch only sync differences between local and remote, hence avoiding to do a whole check out of a solution. Past exectution of command, every further commits on the working copy will occur on the distant repository folder which's been switched to, which's been targeted. No matter what the initial check out was for that local folder.
I am having a task of SVN Merge. But i am not sure hows SVN perform it.
Details:
we have Trunk & On Revision 99 we cut a branch called "code_2011".
Two different group of developer are working one on Trunk, another on branch.
Respective developer are committing their code.
Now both Trunk and branch has changed.
Now After code freeze we have Trunk on revision 200 and Branch on 299.
Now we want to merge the code on Trunk.
Both repositories are clean, now i right clicked on Trunk folder and clicked merge. but i am unable to understand the terminologies start-URl & Revision then End-URL & Revision. so that i can have final code from both repository on Trunk with all revision history stuff.
Could somebody Tell me how its done. & Is it different when i merge the from Trunk to Branch.
Thanks
It's not logically different when you merge from branch to trunk or vice-verse.
Follow these steps for merging code from branch to trunk (Basic merging)-
Checkout the working copy of the trunk (Destination, where the merge is to be done).
Right Click on the Trunk and select TortoiseSVN > Merge
select the First option "Merge a Range of revisions"
Select the Branch URL to merge from.
For Revision range to merge, click on show log. It will show you the complete change log of the branch. Select all the revision that you want to merge (Ctrl+A) for all of them and select OK.
In the next dialog box, select Test Merge. It will show you the Test merge results, you can check if there are any conflicts or the merge is clean.
Finally, Merge.
This process will merge all the branch changes in your trunk's working copy (Local checkout). You need to commit the code after that.
Also, in case of conflicts, TortoiseSVN will automatically give you option to "Edit Conflicts" to resolve them using SVN Editor or leave them so they you can manually resolve them.
Hope this helps.
Cheers!
Post the merge activity, you can also see the from-branch history in log.
There is an option at the bottom of show-log window: stop on copy/rename. Just deselect it, you will get to see all the affected revisions.
we cut branch from Trunk. Changes are done on both trees and committed. Now we want to merge branch to trunk with all the revision history from both. Is it possible?
Is manual merge is different from tortoise SVN merge say i have to do 3-4 files?
"Means i manually check the changes then do it on trunk and commit the trunk."
I earlier put a question regarding it but still confused.
Experts comment only.
Thx
You should be able to merge from your branch to trunk by simply right clicking on the target branch and selecting merge. Typically, a reintegrate merge will merge all changes from a branch back into the target branch. I have had failures with that in the past based on the version of svn, how merges have been done in the past, etc. At that point, I simply would do a 'Merge revision range' without specifying a revision. It then picked up the appropriate ranges to merge and successfully pulled those over to trunk.
Once the merge is done, you must commit the merges. Simply put, the merge operation completes on your local working copy. You will then have to commit the changes to your working copy in order for others to pick it up. I recommend doing merges on clean copies of branches/targets (meaning you have no outstanding changes on either branch). Also, make sure you commit any property changes as well.
Lastly, if you just want to merge a specific change, you can specify the revision in which the change was made instead of doing a full merge/reintegration.
I'm using TortoiseSVN without an external Subversion server to manage LabView source (i.e. a large collection of ever-changing binary files).
I'd like to have a "beta" branch of the repository that anyone can subscribe to and get daily updates. I guess this is different from a usual beta release series with separate branches, but it's right for this project.
What is the best/easiest way to copy the contents of a particular revision of the trunk branch over to the beta branch? Essentially what I want to do is delete the old contents of beta and insert new contents. Delete+add would work, I suppose, but it's clearly suboptimal. Merge is not an option unless I can get Tortoise to automatically resolve all conflicts in the trunk's favor, including deleting files.
Update: a couple people have asked why I don't want delete+add. I'd like a cleaner alternative.
This method leads to half the updates to the beta tree being "wipe out last rev."
The updates are not atomic so someone could pick up an empty release.
I haven't tried and seen, but beta wouldn't be a proper branch. Would the revision log even track multiple revisions at all, since it's a "new" file each time?
Update 2: svn allows any arbitrary commands before a commit, but I couldn't get Tortoise to work this way. After selecting "Delete," stub directories were still left over until I committed, at which point I could repopulate the branch. There needs to be a way to unmark a directory for deletion when it exists in both the old and new tag revisions.
Merge is not an option unless I can
get Tortoise to automatically resolve
all conflicts in the trunk's favor,
including deleting files.
I don't know about TortoiseSVN, but if you install the command line client you could do the following to merge the latest trunk changes to a beta branch:
cd c:/path/to/my/working/copy/of/beta/branch
svn merge file:///c:/path/to/my/repository/trunk --accept theirs-full
svn commit -m "merged latest trunk changes to beta branch"
The --accept theirs-full option resolves all conflicts by using the trunk's version like you want.
This has some advantages: subversion will do representation sharing, so files stored on both branches will not take extra space in the repository. Also, when users update their beta working copy, only the files that were changed need to be pulled over the wire.
SVN is transactional - a delete and copy (not add!) would not be problematic. And beta would be a proper branch (or better a tag)
Why not delete beta/* and then copy trunk/* to beta/ ?
