Truncation is most likely removing the most valuable disambiguation part of the filename. ie. host and path are more likely to be used for multiple SRC_URIs. Additionally the various git.py, svn.py... have a better view of the string and thus can do a better job of handling how best to shrink the filename. For example for git it makes sense to keep the hostname and drop the first parts of the pathname (again they are more likely to be non-unique). Instead of just dropping characters should we instead use some sort of ellipses? Is there any opportunity to know that a PREMIRROR is being used which we can drop? Maybe we should just start to catching the overflow occurrences and providing a better error/warning message. 96106 3 randy.macleod 2023-07-26 21:22:07 +0000 Bulk move of 64 bugs to 4.3 M3 after a quick review.
