This vercmp issue has been a sticking point but this should resolve many of the issues that have come up. Only a few minor code changes were necessary to get the behavior we desired, and this version appears to beat any other vercmp rendition on a few more cases added in this commit. This commit passes all 58 vercmp tests currently out there. Other 'fixes' still fail on a few tests, namely these ones: test: ver1: 1.5.a ver2: 1.5 ret: -1 expected: 1 ==> FAILURE test: ver1: 1.5 ver2: 1.5.a ret: 1 expected: -1 ==> FAILURE test: ver1: 1.5-1 ver2: 1.5.b ret: 1 expected: -1 ==> FAILURE test: ver1: 1.5.b ver2: 1.5-1 ret: -1 expected: 1 ==> FAILURE 4 of 58 tests failed Signed-off-by: Dan McGee <dan@archlinux.org> --- Xavier- I had to get this fixed somehow. :) The challenge is back to you. -Dan doc/pacman.8.txt | 2 +- lib/libalpm/package.c | 26 ++++++++++++++------------ pactest/vercmptest.sh | 36 +++++++++++++++++++++++++++++++++--- 3 files changed, 48 insertions(+), 16 deletions(-) diff --git a/doc/pacman.8.txt b/doc/pacman.8.txt index 9e56a54..0a632ea 100644 --- a/doc/pacman.8.txt +++ b/doc/pacman.8.txt @@ -67,7 +67,7 @@ You can also use `pacman -Su` to upgrade all packages that are out of date.
