83be99e78c Immediately process incoming messages. 
This required moving message processing into the Storage class.

5823e3c780 Storage: Add CreateEntry function for Dispatcher use. 2015-07-28 22:06:42 -07:00

a0d30ffef1 Storage: Use StringMap instead of ConcurrentQueue for updates. 
Updates are merged or themselves updated as user code changes.  This avoids
the need for the dispatcher to do this and also avoids the need for disabling
updates when the dispatcher isn't running, because there's no risk of memory
usage piling up.

fb1b82e239 StorageEntry: Also store copy of name here. 
This wastes a bit of space but is necessary for assign message generation.

3bc5699ba1 Storage: Provide accessor for global mutex. 2015-07-26 09:42:14 -07:00

18659257d3 Storage: Make setters globally atomic. 
Previously, setters were locally but not globally atomic because they
used GetEntry() (globally atomic) in conjunction with locally atomic
gets/sets to the StorageEntry.  To support synchronizing network handshakes
they need to be globally atomic.

GetEntry() has been removed due to this issue, so a helper was added to
StorageTest instead.

8fa0e6c914 Add shims for old NetworkTable interface. 
This provides classes for virtual subtables using path delimiters within
the global NetworkTable namespace.
 2015-07-23 01:23:09 -07:00
Peter Johnson
6f940bcaaf Add immediate_notify and is_new to entry listener. 
On the callback function, is_new indicates the value is newly added.

On adding a callback function, immediate_notify indicates the callback
should be called once (with is_new=true) for each matching entry that
already exists.

79f732f239 Import llvm::SmallString and dependencies. 
Update StringRef and StringExtras with SmallVector functions.
 2015-07-22 22:29:46 -07:00

593bc28446 Move StringMap.h and StringExtras.h to public includes. 
While these aren't required by the public interface, they are generally
useful classes for users of the library.

5df62ac172 Storage: Disable use of update queue by default. 
This ensures we don't "leak" memory for local use when the dispatch thread
is not running.
