Changes between Initial Version and Version 1 of Ticket #51857, comment 56

initial	v1
1	1	An alternative option would be to flip this around, and not add a rollback functionality into it, but rather install into a temporary directory first, and then remove existing/rename new into place.
	2
	3	(edit: I guess that's kind of how it works now, except the temporary install directory is wp-content/upgrade/somethinghere. It's the copy from there to the plugins directory that sometimes fails, so avoiding that copy by extracting into the plugins directory in the first place and then performing a move() would mean far less IO is needed and as a result could be faster too)
2	4
3	5	That would result in less downtime of the plugin not existing on the site, and also not delete the plugin from the site in the event of a failure to create the new files.
