#rb Per.Larsson, Devin.Doucette #jira UE-133497 #rnx #preflight 61f835491c5ac5523462810a - A lot of files have been touched but most of this is changing FPayload::IsValid to !FIoHash::IsZero, the main changes are in EditorBulkData/EditorBulkDataTests - The only difference between FPayloadId and FIoHash is that the former considered the hash of an invalid or empty buffer to be 'invalid' too where as FIoHash would return a valid hash -- To keep behaviour the same, we only hash payloads in EditorBulkData using a utility method ::HashBuffer which will not hash empty or invalid payloads and return a default FIoHash instead. -- Unit tests have been extended to prove that the behaviour has not changed. #ROBOMERGE-AUTHOR: paul.chipchase #ROBOMERGE-SOURCE: CL 18806362 in //UE5/Release-5.0/... via CL 18808527 via CL 18821790 #ROBOMERGE-BOT: UE5 (Release-Engine-Test -> Main) (v908-18788545) [CL 18822154 by paul chipchase in ue5-main branch]

* This backend can be used to access payloads stored in source control.
|
|
* The backend doesn't 'check out' a payload file but instead will just download the payload as
|
|
* a binary blob.
|
|
* It is assumed that the files are stored with the same path convention as the file system
|
|
* backend, found in Utils::PayloadIdToPath.
|
|
*
|
|
* Ini file setup:
|
|
* 'Name'=(Type=SourceControl, DepotRoot="//XXX/")
|
|
* Where 'Name' is the backend name in the hierarchy and 'XXX' is the path in the source control
|
|
* depot where the payload files are being stored.
|
|
*
|
|
* Optional Values:
|
|
* UsePartitionedClient: When true the temporary workspace client created to submit payloads
|
|
* from will be created as a partitioned workspace which is less overhead
|
|
* on the source control server. If your server does not support this then
|
|
* use false. [Default=True]
