The below changes were from Alexander Belopolsky. When I tried to push my changes, my changes resulted in multiple heads in 2.7, so I had to go back 2.7 branch, merge 2.7 and then commit and push. This resulted in both my changes as well as merged changes being pushed. I understand that the second part should not happen, like merging an already available change and then pushing it again. I have a script which kind of traverses all the local directories of branches and does a hg pull; hg update before I start making changes and I thought that was enough. How could the push would resulted in two heads here and why I did have merge ? ( I am unable to traceback the steps) and if there is anything I should know, or change in the workflow when doing changes to 2.7, please let me know.
