Add feature to change http timeout directly in httpcli store in aws client Add copy/MPUCopy function Update mpu to allow copy with MPU Package Cobra Fix println by fmt.Fprint to os.stdout Package Crypt Refactor package to use instance of crypt instead of a global crypt unique instance Allow to gen key/nonce Add io stream reader/writer instead of only buffer slice encoder decoder Package file/bandwidth Add new subpackage bandwith to limit a amount of byte read/write for a duraction Use file/progress function increment/reset Allow to add custom function increment / reset Package IOUtils Remove useless file error.go, tempFile.go (replaced by package file) Move fileDescriptor to a subpackage fileDescriptor: allow to change nb of FD for linux/windows os Move Buffer ReadCloser to a new subpackage: allow to add close function to buffer, and expose read / write io interface Add sub package multiplexer to allow send/receive multiple io stream into on io stream Package Socket Rework to expose io stream instead of buffer Fix minor bugs Other: Bump dependencies Update code following bump dependencies
