This simplifies the critical section of xcb_send_request and fixes a couple of subtle bugs: - It's possible for xcb_send_request to need to issue two sync requests before it can issue the real request. Previously, we counted sequence numbers as if both were issued, but only one went out on the wire. - The test for whether to sync at 32-bit sequence number wrap has been incorrect since we switched to 64-bit sequence numbers internally. This change means that if the output queue was already full and the current request is bigger than the output queue, XCB will do one more write syscall than it did before. But syncs are rare and small requests are the norm, so this shouldn't be a measurable difference. Signed-off-by: Jamey Sharp <jamey@minilop.net> |
