In preparation for non-cooperative preemption, this CL abstracts this into general purpose suspendG/resumeG functions. suspendG and resumeG closely follow the existing scang and restartg functions with one exception: the addition of a _Gpreempted status. Currently, preemption tasks (stack scanning) are carried out by the target goroutine if it's in _Grunning. In this new approach, the task is always carried out by the goroutine that called suspendG. Thus, we need a reliable way to drive the target goroutine out of _Grunning until the requesting goroutine is ready to resume it. The new _Gpreempted state provides the handshake: when a runnable goroutine responds to a preemption request, it now parks itself and enters _Gpreempted. The requesting goroutine races to put it in _Gwaiting, which gives it ownership, but also the responsibility to start it again. This CL adds several TODOs about improving the synchronization on the G status. The existing code already has these problems; we're just taking note of them. The next CL will remove the now-dead scang and preemptscan. For #10958, #24543.

To handle this, stack copying acquires the locks for the channels a goroutine is waiting on. One complication is that stack growth may happen while a goroutine holds these locks, in which case stack copying must *not* acquire these locks because that would self-deadlock. Currently, stack growth never acquires these locks because stack growth only happens when a goroutine is running, which means it's either not blocking on a channel or it's holding the channel locks already. Stack shrinking always acquires these locks because shrinking happens asynchronously, so the goroutine is never running, so there are either no locks or they've been released by the goroutine. However, we're about to change when stack shrinking can happen, which is going to break the current rules. Rather than find a new way to derive whether to acquire these locks or not, this CL simply adds a flag to the g struct that indicates that stack copying should acquire channel locks. This flag is set while the goroutine is blocked on a channel op. For #10958, #24543.

That's okay for scanning the stack (conservatively), but not for shrinking the stack. Hence, this CL prepares for this by only shrinking the stack as part of the stack scan if the goroutine is stopped at a synchronous safe point. Otherwise, it queues up the stack shrink for the next synchronous safe point. We already have one condition under which we can't shrink the stack for very similar reasons: syscalls. Currently, we just give up on shrinking the stack if it's in a syscall. But with this mechanism, we defer that stack shrink until the next synchronous safe point. For #10958, #24543.

Instead, we now make the directory read-only, which (on most platforms) suffices to prevent the removal of its files.

2019 17:05:56 -0400 Subject: [PATCH 020/107] runtime: M-targeted signals for BSDs For these, we split up the existing runtime.raise assembly implementation into its constituent "get thread ID" and "signal thread" parts. This lets us implement signalM and reimplement raise in pure Go. (NetBSD conveniently already had lwp_self.) We also change minit to store the procid directly, rather than depending on newosproc to do so. This is because newosproc isn't called for the bootstrap M, but we need a procid for every M. This is also simpler overall. For #10958, #24543.

For instance, we know that A<=N1<=B and we learn that B<=A, we can deduce A==N1==B, and thus we can collapse all paths from A to B into a single aliased node. Currently, this is a TODO. This CL implements the path-collapsing primitive by doing a DFS walk to build a bitset of all nodes across all paths, and then calling the new aliasnodes that allow to mark multiple nodes as aliases of a single master node. This helps only 4 times in std+cmd, but it will be fundamental when we will rely on poset to calculate numerical limits, to calculate the correct values. This also fixes #35157, a bug uncovered by a previous CL in this serie. A testcase will be added soon.

However, we've learned from Microsoft that there are several undocumented secret registry types that are in use by various parts of Windows, and we've learned from inspection that many Microsoft uses of registry types don't strictly adhere to the recommended value size. It's therefore foolhardy to make any assumptions about what goes in and out of the registry, and so this test, as well as its "blacklist", are meaningless.

Clulow" Date: Mon, 28 Oct 2019 09:19:48 -0700 Subject: [PATCH 042/107] runtime: make NumCPU respect zone CPU cap on illumos On illumos systems, check for the "zone.cpu-cap" resource control when determining how many usable CPUs are available. If the resource control is not set, or we are unable to read it, ignore the failure and return the value we used to return; i.e., the CPU count from sysconf(_SC_NPROCESSORS_ONLN).

Essentially, cmd/dist acts as a minimal version of 'go install' when building go_toolchain. Until now, cmd/go has had no transitive dependencies in vendor directories. This changes in CL 202698, where several packages are deleted and equivalent versions in golang.org/x/mod are used instead. So this CL adds support to cmd/dist for vendor directories.

Cherry Zhang Date: Sat, 26 Oct 2019 22:48:15 -0400 Subject: [PATCH 057/107] cmd/internal/obj/mips: fix encoding of FCR registers The asm encoder generally assumes that the lowest 5 bits of the REG_XX constants match the machine instruction encoding, i.e. the lowest 5 bits is the register number. This was not true for FCR registers and M registers. Make it so. MOV Rx, FCRy was encoded as two machine instructions. The first is unnecessary. Remove.

However, this was not true generally, as witnessed by issue #35213, which has a non-SSAable field reference of a struct that is not converted to an autotmp. So, I fixed openDeferSave() to handle non-SSAable nodes more generally, and make sure that these non-SSAable expressions are not evaluated more than once (which could incorrectly repeat side effects).

The revert CL included regression tests, while this CL includes a fixed version of the original change. In particular, what we forgot in the original optimization was that we still need the length and trailing quote checks at the beginning of unquoteBytes. Without those, we could end up in a crash later on. We can work out how many bytes can be unquoted trivially in rescanLiteral, which already iterates over a string's bytes. Removing the extra loop in unquoteBytes simplifies the function and speeds it up, especially when decoding simple strings, which are common. While at it, we can remove the check that s[0]=='"', since all call sites already meet that condition. name old time/op new time/op delta CodeDecoder-8 10.6ms ± 2% 10.5ms ± 1% -1.01% (p=0.004 n=20+10) name old speed new speed delta CodeDecoder-8 183MB/s ± 2% 185MB/s ± 1% +1.02% (p=0.003 n=20+10) Updates #28923.

Currently, several important fields of a heap span are set by heapBits.initSpan, which happens after the span has already been published and returned from the locked region of alloc_m. In particular, allocBits is set very late, which makes mspan.isFree unsafe even if you were to lock the heap because it tries to access allocBits. This CL fixes this by populating these fields in alloc_m. The next CL builds on this to only publish the span once it is fully initialized. Together, they'll make it safe to check allocBits even if there is a race with alloc_m. For #10958, #24543, but a good fix in general.

However, in various cases, we try to be defensive against bad pointers. In findObject, this is just a sanity check: we never expect to find a bad pointer, but programming errors can lead to them. In spanOfHeap, we don't necessarily trust the pointer and we're trying to check if it really does point to the heap, though it should always point to something. Conservative scanning takes this to a new level, since it can only guess that a word may be a pointer and verify this. In all of these cases, we have a problem that the span lookup and check can race with span initialization, since the span becomes visible to lookups before it's fully initialized. Furthermore, we're about to start initializing the span without the heap lock held, which is going to introduce races where accesses were previously protected by the heap lock. To address this, this CL makes accesses to mspan.state atomic, and ensures that the span is fully initialized before setting the state to mSpanInUse. All loads are now atomic, and in any case where we don't trust the pointer, it first atomically loads the span state and checks that it's mSpanInUse, after which it will have synchronized with span initialization and can safely check the other span fields. For #10958, #24543, but a good fix in general.
