See the entry for "push.default" in "git help config".
The "tracking" setting does seem more sensible and intuitive, given that current git practice requires setting up explicit tracking relationships between branches.
For example, I find it surprising, perhaps even alarming, that by default, git will try and push my changes on branch A to the branch origin/A - even if I created it to track origin/B. Why allow the possibility of A tracking a non-matching branch origin/B, and have the default push setting ignore that?
Not only that, but I frequently get asked by puzzled colleagues, new to git, why "git push" seems to fail all the time when they're pushing their changes. (The errors arise because of the default "matching" setting: many of the matching branches fail to push cleanly because the remote branch has silently changed. My latest answer is to tell them to set push.default to "tracking", or to do that for them.)
I'm curious: why isn't "tracking" the default and recommended option? "Historical reasons" might explain the first, but not the second.
