Normally I would blame an outdated repository, but perl has never required pcre. Therefore my question. My only explanation is a cut-and-paste mistake.
That command needs to be applied to all subpackages of pcre source package. E.g. pcre-utf16 adds "sigil" to a heap of affected packages. No command is universally good, because it always depends on what you want to get. Recently there was a thread discussing these queries at length. I think your command is good enough to get a quite accurate view on the affected packages. I would only apply --srpm option to see components instead of binary packages. Then the list shrinks to managable 105 components. That's not so much. Of course there are some high-profile componentes like grep, 389-ds-base, swig, kdelibs, postfix, and swig. And some of them will be very expensive to port (either because they use pcre extensively, or abuses a private API, or the code is simply too old and nobody wants to touch it), but that's a life and I think with help by their maintainers and upstreams, it's not impossible. Of course not in a month until F37. It will require some time. More disappointing is a majority of niche components whose upstream is dead or not motivated to port. Those will need to go. A problem of pcre is that it's too good. Applications which do not need a thread safety, latest Unicode features, or few per cents of performance, won't see a benefit in the port. -- Petr
