strange incremental patch size [2.6.12-rc2 to 2.6.12-rc3]

strange incremental patch size [2.6.12-rc2 to 2.6.12-rc3]

[Maciej Soltysiak]

Hi,

These are the sizes of rc2 and rc3 patches

# ls -la patch-2.6.12*
-rw-r--r--  1 root src 18011382 Apr  4 18:50 patch-2.6.12-rc2
-rw-r--r--  1 root src 19979854 Apr 21 02:29 patch-2.6.12-rc3

Let us make an incremental patch from rc2 to rc3

# interdiff patch-2.6.12-rc2 patch-2.6.12-rc3 >x

Let us see how big it is.
# ls -ld x
-rw-r--r--  1 root src 37421924 Apr 21 12:28 x

How come interdiff from rc2 (18MB) to rc3 (20MB) gave me
37MB worth of patch-code ? I would expect something about
2MB but 40MB ?

The patching with the incremental patch took very long compared
to other rc2-rc3-type patches, that is how I noticed it.

Regards,
Maciej

The order in the patch changed a lot. The rc2 patch starts with the
changes in the CREDITS file and the rc3 patch has those starting at line
151839.  This is probably because Linus now uses different tools to
produce these. Maybe you can somehow sort the rc2 patch in the same way
as the rc3 patch (same file order) before using interdiff, that should
solve it.

Try interdiff -p1?
