It has 'bad' directory structure and I want to 'fix' it after each incremental update from cvs. Here is the idea: I have 2 permanent branches master (to work with) and cvs (to import from cvs) and one temporary branch to move files across the project to make directory structure better. Movement operation is always the same: move directories/files from one place to another. But merging from temp branch to work branch fail with error text : CONFLICT (rename/delete): Rename a->b/a in HEAD and deleted in 791371 Here is the example script: >git version git version 1.4.4 > mkdir 1 && cd 1 && git init-db defaulting to local storage area > echo 1 > a && git add a && git commit -a -m '1' Committing initial tree 2ce1eef76631e82282e0f7f0cf9e6f3e9a4a0b1e > git checkout -b fix > mkdir b && git mv a b/ && git commit -a -m 'fix 1' > git checkout -b work master > git pull . fix Updating 7be4ab0..d4909bb Fast forward a => b/a | 0 1 files changed, 0 insertions(+), 0 deletions(-) rename a => b/a (100%) > git checkout -f master > echo 2 >> a && git commit -a -m '2' > git checkout -b fix2 master > mkdir b && git mv a b/ && git commit -a -m 'fix 2' > git checkout -f work > git pull . fix2 Trying really trivial in-index merge... fatal: Merge requires file-level merging Nope.

Why git can't merge such changes ? It should know that work holds renamed version of file a from master and fix2 holds new renamed file a from master too. Why it can't apply changes of a from master to work ``` ## Junio C Hamano, 2006-11-16 11:32 Subject: Re: Git can't merge two identical move file operation Message-ID: <7v1wo3bp99.fsf@assigned-by-dhcp.cox.net> URL: https://gitlist.dev/e/7v1wo3bp99.fsf%40assigned-by-dhcp.cox.net In-Reply-To: <6e1787fe0611160226r2d51d980t6899f1a1018b5fe5@mail.gmail.com> ``` "Alexander Litvinov" writes: > Here is the example script: >>git version > git version 1.4.4 >> mkdir 1 && cd 1 && git init-db > defaulting to local storage area >> echo 1 > a && git add a && git commit -a -m '1' > Committing initial tree 2ce1eef76631e82282e0f7f0cf9e6f3e9a4a0b1e Could you try an exactly the same sequence except to make the initial contents of the file 'a' a bit more meaningful (I typically use COPYING file in git.git repository for something like this), by replacing the above "echo 1 > a ..." line with: $ cat COPYING >a && git add a && git commit -a -m '1' and see if it still breaks?

It works ! ``` ## Alexander Litvinov, 2006-11-16 12:23 Subject: Re: Git can't merge two identical move file operation Message-ID: <200611161823.39056.litvinov2004@gmail.com> URL: https://gitlist.dev/e/200611161823.39056.litvinov2004%40gmail.com In-Reply-To: <7v1wo3bp99.fsf@assigned-by-dhcp.cox.net> ``` В сообщении от Thursday 16 November 2006 17:32 Junio C Hamano написал(a): > Could you try an exactly the same sequence except to make the > initial contents of the file 'a' a bit more meaningful (I > typically use COPYING file in git.git repository for something > like this), by replacing the above "echo 1 > a ..." line with: > > $ cat COPYING >a && git add a && git commit -a -m '1' > > and see if it still breaks?
