I've started playing with Git and have come across the terms "upstream" and "downstream". I've seen these before but never understood them fully.

When you make changes, you usually want to send them back " upstream " so they make it into that repository so that everyone pulling from the same source is working with all the same changes.
This is mostly a social issue of how everyone can coordinate their work rather than a technical requirement of source control. You want Lorem lpsum 277 boatplans/plans/free-diy-boat-building-plans read article get your changes into the main project so you're not tracking divergent lines of development. Sometimes you'll read about package or release managers the people, not the tool talking about submitting changes Upstream And Downstream In Maths Quest Upstream And Downstream In Maths Quest to "upstream".
That usually means they had to adjust the original sources so they could create a package In Downstream Maths Quest And Upstream for their. They don't want to keep making those changes, so if they send them "upstream" to the original source, Upstream And Downstream Questions Linear Equations 20 they shouldn't have to deal with the same issue in the next release.

Those notions are always relative between two repos and depends on the way data flows:.
The DVCS Distributed Version Control System twist is: you have no idea what downstream actually is, beside your own repo relative to the remote repos you have declared. In term of " flow of Lorem lpsum 277 boatplans/small-boats/small-boat-drawing click to see more ", your repo is at the Upstream And Downstream In Maths Quest bottom "downstream" of a flow coming from upstream repos "pull from" and going back to the same or other upstream repos "push to".
It means you are pulling from an "upstream" repo where a rebase took placeand you the "downstream" repo is stuck with the consequence lots of duplicate commits, because the branch rebased upstream Upstream And Downstream In Maths Quest recreated the commits of the same branch you have locally. That is bad because for one "upstream" repo, there can be many downstream repos i.
Again, with the "flow of data" analogy, in a DVCS, one bad command "upstream" can have a " ripple effect " downstream. Note: this is not limited to data.
