It seem that -Su and -S package version check are different and the -S is wrong.

I have done a pacman -Syu to list all the needed upgrade.
(I'll cut of the unecessary package form the output to have it more clear)

pacman -Su

Targets: libmysqlclient-5.0.24a-1 mysql-5.0.24a-1 mysql-clients-5.0.24a-1

Then I started to upgrage the package using -S optin and specifing the package:

Pacman -S libmysqlclient mysql mysql-clients

:: libmysqlclient-5.0.24-1: local version is newer. Upgrade anyway? [Y/n] y
:: mysql-5.0.24-2: local version is newer. Upgrade anyway? [Y/n] y
:: mysql-clients-5.0.24-1: local version is newer. Upgrade anyway? [Y/n] y

Targets: libmysqlclient-5.0.24a-1 mysql-5.0.24a-1 mysql-clients-5.0.24a-1

It seem that the -Su option use a differen version check than -S option.

Reason for closing:  Fixed
Additional comments about closing:  Added some code to honor 'force' flag in plain -S operation.

-Su respects the force=y option in PKGBUILDs to upgrade even if the version seems older. -S doesn't seem to respect the force=y flag.

So this mean that the version checking is wrong since 5.0.24a is never than 5.0.24 unless pacman understand the "a" as alpha....
I noticed this also with other package, maybe the version checking should be corrected.

The version checking is _impossible_ to correct when talking about alphanumeric versions. Which of these is greater:
1.0abcd or 1.0abc
1.0a or 1.0A
1.1 or 1.1c

It's utterly impossible to tell.

The best we can do is honor 'force' in -S calls. I will fix this in pacman3.

Looks like this is fixed in pacman3 already. Can someone verify that -S foo respects a FORCE setting for package foo?
Comment by Dan McGee (toofishes) - Tuesday, 06 February 2007, 21:34 GMT
FORCE is now honored by pacman3 with changes made today by Aaron. Tested and marking implemented.
