Russell Hancox	2aacc9266f	Revert changes for building with Xcode 8 (#111 ) * Partial Revert of "Project: Update project files for Xcode 8 (#105)" Building with Xcode 8 (and specifically the 10.12 SDK) breaks logging on 10.12 and on top of that some tests don't pass while working perfectly fine on 10.11. For now, we'll just continue building with 7.3.1. * README: Add note about building with Xcode 7.3.1	2016-10-10 14:24:14 -04:00
Russell Hancox	d648d477bb	santa-driver: Fix deadlocking on Sierra (#107 ) 1. Don't RemoveFromCache for advisory access by santad itself. 2. wakeup sleeping threads when removing from cache 3. Move the vnode type check earlier in the process for the vnode scope	2016-09-28 16:36:23 -04:00

Russell Hancox	8d94324dd6	santad: Update SNTFileWatcher to fix broken dispatch source. (#97 ) I'm not certain if this is a Sierra change or just that it was more rare before but changing a cancel handler on a dispatch source no longer seems to have any effect. This meant the file descriptor for the currently-active source was being closed instead of the one for the source that was just cancelled. It wasn't actually necessary to get the file handle from the source, we can just rely on capturing it in the block, which works just as well.	2016-09-22 15:36:26 -04:00

Russell Hancox	b5921f95f3	santa-driver: Remove the static wrappers in SantaDriverClient (#90 ) SantaDriverClient was implemented to have static functions that call instance methods passing appropriate arguments.
