Fixed the following
Fix for crash when giving publish command when in subscribed mode -- Important
When Giving streams command within transaction the key index was not choose correct for some stream commands like xgroup , xinfo , if it was first command -- Important
when parsing stream commands to check if it has block option , we were checking in correctly at only fixed offsets for BLOCK key word , while the BLOCK can be present at any offset before the STREAMS key word , This is fixed. - Important
For the transaction commands
all the blocking commands are now allowed in to transaction , as the redis itself takes care of converting it in to non blocking
mset and mget are added , as cross slot errors are handled by redis itself
To maintain atomicity of the transaction , if any of the unsupported commands are given at the middle of a valid transaction , when exec command is given at the last its replaced with DISCARD command, so that the transaction is discared , and also the response for DISCARD is just ok , this is unacceptable , so thats also caught and converted to proper error message. - On Need Basis
But still many commands which is handled before transaction iteself is left untouched and they are considered to be not supported within transaction - On Need Basis
