Shawn O. Pearce	3cb59216f5	Avoid unnecessary second read on OBJ_OFS_DELTA headers When we read the object header we copy 20 bytes from the pack data, then start parsing out the type and the inflated size. For most objects, this is only going to require 3 bytes, which is sufficient to represent objects with inflated sizes of up to 2^16. The local buffer however still has 17 bytes remaining in it, and that can be used to satisfy the OBJ_OFS_DELTA header. We shouldn't need to worry about walking off the end of the buffer here, because delta offsets cannot be larger than 64 bits, and that requires only 9 bytes in the OFS_DELTA encoding. Assuming worst-case scenarios of 9 bytes for the OFS_DELTA encoding, the pack file itself must be approaching 2^64 bytes, an infeasible size to store on any current technology. However, even if this were the case we still have 11 bytes for the type/size header. In that encoding we can represent an object as large as 2^74 bytes, which is also an infeasible size to process in JGit. So drop the second read here. The data offsets we pass into the ObjectLoaders being constructed need to be computed individually now. This saves a local variable, but pushes the addition operation into each branch of the switch.

Robin Rosenberg	d4e7b70606	Move pure IO utility functions to a utility class of its own. According the javadoc, and implied by the name of the class, NB is about network byte order. The purpose of moving the IO only, and non-byte order related functions to another class is to make it easier for new contributors to understand that they can use these functions in general and it's also makes it easier to understand where to put new IO related utility functions Change-Id: I4a9f6b39d5564bc8a694b366e7ff3cc758c5181b Signed-off-by: Robin Rosenberg <robin.rosenberg@dewire.com> Signed-off-by: Shawn O.

Alex Blewitt	4d91645e89	Remove trailing whitespace at end of line As discussed on the egit-dev mailing list, we prefer not to have trailing whitespace in our source code. Correct all currently offending lines by trimming them. Change-Id: I002b1d1980071084c0bc53242c8f5900970e6845 Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	14 years ago
