Big deltas or deltas for very small packages are not needed so we should check that and not generate any. Signed-off-by: Florian Pritz <bluewind@xinu.at> Signed-off-by: Dan McGee <dan@archlinux.org>

Name

|
|
pkgdelta - package delta generation utility
|
|
|
|
|
|
Synopsis
|
|
--------
|
|
'pkgdelta' [options] <package1> <package2>
|
|
|
|
|
|
Description
|
|
-----------
|
|
'pkgdelta' is used to create package delta files between two versions of the
|
|
same package. These files are essentially binary patches. linkman:pacman[8] can
|
|
download deltas instead of full package upgrades, and use them with the
|
|
previous versions of packages (in the package cache) to synthesize the upgraded
|
|
version of the packages. This likely reduces download sizes for upgrades
|
|
significantly.
|
|
|
|
'pkgdelta' requires linkman:xdelta3[1] to do its job.
|
|
|
|
Options
|
|
-------
|
|
*--max-delta-size <ratio>*::
|
|
Only create delta files if the delta is smaller than ratio * package_size.
|
|
Possible values: 0.0 to 2.0.
|
|
Recommended values: 0.2 to 0.9.
|
|
Default value: 0.7
|
|
|
|
*--min-pkg-size <size>*::
|
|
Minimal size of the package file in bytes to be considered for delta creation.
|
|
Default value: 1048576 bytes = 1MiB
|
|
|
|
*-q, \--quiet*::
|
|
Be quiet. Do not output anything but warnings and errors.
