Fixes FS#17752
I think I too prefer --no-downgrade.
Trailing whitespace here, could be removed. Some editors can trim this automatically, so can allan when applying. :D
+ local version=$(sed -n '/^%VERSION%$/ {n;p;q}' "$pkgentry/desc") + if (( "$(vercmp $version $pkgver)" > "0" )); then
Neither of these actually need to be quoted, although sure, quoting doesn't hurt. But one of them is an integer literal, and vercmp is guaranteed to produce another integer literal, so there is no word splitting, globbing, or parameter expansion to worry about.
Thanks for the patch. Aside for these style nits and possible bikeshedding over the name of the option, the patch looks good to me, and works as expected. -- Eli Schwartz Bug Wrangler and Trusted User

A package with metadata which makepkg does not allow, could still theoretically be created in some other manner; pacman itself is very forgiving of this. (As mentioned elsewhere, it would be nice if repo-add made use of the linting rules written for makepkg...) -- Eli Schwartz Bug Wrangler and Trusted User
I'm totally going to follow this suggestions, thanks! When it comes to bash I always have doubts about quoting. I'll wait a bit before resubmitting to see opinions about the flag name decision (--no-downgrade or whatever) if that's fine. :) ekarndam On 28/04/19 19:11, Eli Schwartz wrote:

Adding a commit message with a brief description of what this patch does would be great. Also add a line with the number of the bug it fixes. I do not like --dont-downgrade because of the "dont". Abbreviations should be avoided. I'm also not a fan of "--no-downgrade" How about "--prevent-downgrades" and adding a short option? "-p" or "-d" would work. Otherwise, happy with the patch. Quoting the arguments to vercmp would not hurt. Thanks, Allan

The "p" puts emphasis on the prevention, the "d" puts emphasis on the downgrade. So I prefer the former. The "d" also collides with the --delta option that was just removed, which would have surprising results in scripts that still use -d, while not being particularly advantageous as a shortopt name. -- Eli Schwartz Bug Wrangler and Trusted User

Good point about deltas. Go with "-p" as the short option. A
