Hi Jan,
This happens because find_pkgentry() fails to account the case where globbing fails and the expression is taken literally.
Maybe we should use failglob instead to provoke an error?
Wouldn't nullglob be better to skip the loop's body?
$ touch foo bar $ ls bar foo $ $ shopt -u nullglob failglob $ for f in *; do echo = $f; done = bar = foo $ rm foo $ for f in *; do echo = $f; done = bar $ rm bar $ for f in *; do echo = $f; done = * $ $ touch foo bar $ shopt -s nullglob $ for f in *; do echo = $f; done = bar = foo $ rm foo $ for f in *; do echo = $f; done = bar $ rm bar $ for f in *; do echo = $f; done $
All three of you are wrong, or at least missing the point. :)
[[ foo = f* ]] is defined to have pattern-matching context, and in this case, [[ pkgname* = pkgname** ]] matches true. If we do not want this behavior, we need to quote this -- and by properly quoting where we are supposed to quote, we don't need to stat for file existence, we don't need to change the way the whole script handles globs, and we still get the failing action we want. To be more precise, we get the exact behavior and method of acquiring that behavior, which was originally intended.
There are also other cases where this could matter, some of which are long shots.
We probably need to work on the enforcement of pkgname rules from makepkg into repo-add as well: pkgname (array) Either the name of the package or an array of names for split packages. Valid characters for members of this array are alphanumerics, and any of the following characters: “@ . _ + -”. Additionally, names are not allowed to start with hyphens or dots. Can probably link in libmakepkg into here to do so. Although I'd like to move repo-add to using libalpm, and we need to enforce rules here too... Allan
