only the references are deleted. Even though here the department is definitely eradicated over the distant, the references to it even now exists in the area repositories within your staff customers. Because of this for other team associates the deleted branches remain obvious if they do a git branch -a.
Working with scandir() in place of listdir() can substantially increase the efficiency of code that also wants file kind or file attribute information, for the reason that os.DirEntry objects expose this facts In the event the operating method offers it when scanning a Listing.
when two threads access the identical place in memory at the same time, and no less than among the accesses is actually a publish

Now, I've added some new files, modified current information, and designed independent commits on Each and every branch, then pushed them towards the origin. The graph now looks like this:

You'll be able to thoroughly clean up that info regionally similar to this: git remote prune origin Your local copies of deleted branches are not eradicated by this. The identical outcome is accomplished through the use of git fetch --prune
A race situation occurs when two or more threads can access shared facts plus they try to change it concurrently. Since the thread scheduling algorithm can swap between threads Anytime, you do not know the buy through which the threads will try to accessibility the shared details.
