[libvirt] [PATCH] maint: drop spurious semicolons
I noticed a line 'int nparams = 0;;' in remote_dispatch.h, and tracked down where it was generated. While at it, I found a couple of other double semicolons. Additionally, I noticed that commit df0b57a95 left a stale reference to the file name remote_dispatch_bodies.h. * src/conf/numatune_conf.c (virDomainNumatuneNodeParseXML): Drop empty statement. * tests/virdbustest.c (testMessageStruct, testMessageSimple): Likewise. * src/rpc/gendispatch.pl (remote_dispatch_bodies.h): Likewise, and update stale comments.

Pushing under the trivial rule.
Syntax check can't easily catch this, because we want to allow 'for (int i = 0;; i++)' on a loop that uses break to exit, so this is just done by manual inspection.
But trying ';;$' it looks like it can. And trying it out it seems there's still one place left. Before your patch: git ls-files | grep '\.[chx]' | xargs grep ';;$' src/conf/numatune_conf.c: int n = 0;; src/xenconfig/xen_common.c: return -1;; tests/virdbustest.c: double in_double = 3.14159265359, out_double = 0;; tests/virdbustest.c: double in_double = 3.14159265359, out_double = 0;; And after your patch: git ls-files | grep '\.[chx]' | xargs grep ';;$' src/xenconfig/xen_common.c: return -1;; Martin

Oh cool, looks like I have a followup patch to write, then.
And after your patch: git ls-files | grep '\.[chx]' | xargs grep ';;$' src/xenconfig/xen_common.c: return -1;;
