02e5505858 [release-branch.go1.16] cmd/go: avoid +incompatible major versions if a go.mod file exists in a subdirectory for that version
Previous versions of the 'go' command would reject a pseudo-version
passed to 'go get' if that pseudo-version had a mismatched major
version and lacked a "+incompatible" suffix. However, they would
erroneously accept a version *with* a "+incompatible" suffix even if
the repo contained a vN/go.mod file for the same major version, and
would generate a "+incompatible" pseudo-version or version if the user
requested a tag, branch, or commit hash.

This change uniformly rejects "vN.…" without "+incompatible", and also
avoids resolving to "vN.…+incompatible", when vN/go.mod exists.
To maintain compatibility with existing go.mod files, it still accepts
"vN.…+incompatible" if the version is requested explicitly as such
and the repo root lacks a go.mod file.

a222963bc4 [release-branch.go1.16] cmd/compile: correct type of pointer difference on RISCV64
Pointer comparison is lowered to the following on RISCV64

(EqPtr x y) => (SEQZ (SUB <x.Type> x y))

The difference of two pointers (the SUB) should not be pointer
type. Otherwise it can cause the GC to find a bad pointer.

8a24f67ca7 [release-branch.go1.16] runtime: simplify histogram buckets considerably
There was an off-by-one error in the time histogram buckets calculation
that caused the linear sub-buckets distances to be off by 2x.

The fix was trivial, but in writing tests I realized there was a much
simpler way to express the calculation for the histogram buckets, and
took the opportunity to do that here. The new bucket calculation also
fixes the bug.

For #50732.
Fixes #50733.

288ff40bf9 [release-branch.go1.16] net: increase maximum accepted DNS packet to 1232 bytes
The existing value of 512 bytes as is specified by RFC 1035.
However, the WSL resolver reportedly sends larger packets without
setting the truncation bit, which breaks using the Go resolver.
For 1.18 and backports, just increase the accepted packet size.
This is what GNU glibc does (they use 65536 bytes).

For 1.19 we plan to use EDNS to set the accepted packet size.
That will give us more time to test whether that causes any problems.

No test because I'm not sure how to write one and it wouldn't really
be useful anyhow.

2b65cde586 [release-branch.go1.16] regexp/syntax: reject very deeply nested regexps in Parse
The regexp code assumes it can recurse over the structure of
a regexp safely. Go's growable stacks make that reasonable
for all plausible regexps, but implausible ones can reach the
“infinite recursion?” stack limit.

This CL limits the depth of any parsed regexp to 1000.
That is, the depth of the parse tree is required to be ≤ 1000.
Regexps that require deeper parse trees will return ErrInternalError.
A future CL will change the error to ErrInvalidDepth,
but using ErrInternalError for now avoids introducing new API
in point releases when this is backported.

Fixes #51112.
Fixes #51117.

de76489a1b [release-branch.go1.16] cmd/go/internal/modfetch: do not short-circuit canonical versions
Since at least CL 121857, the conversion logic in
(*modfetch).codeRepo.Stat has had a short-circuit to use the version
requested by the caller if it successfully resolves and is already
canonical.

However, we should not use that version if it refers to a branch
instead of a tag, because branches (unlike tags) usually do not refer
to a single, stable release: a branch named "v1.0.0" may be for the
development of the v1.0.0 release, or for the development of patches
based on v1.0.0, but only one commit (perhaps at the end of that
branch — but possibly not even written yet!) can be that specific
version.

We already have some logic to prefer tags that are semver-equivalent
to the version requested by the caller. That more general case
suffices for exact equality too — so we can eliminate the
special-case, fixing the bug and (happily!) also somewhat simplifying
the code.

the instruction does not do the extension. So we cannot elide the
extension.

169be8e5b1 [release-branch.go1.16] runtime: set iOS addr space to 40 bits with incremental pagealloc
In iOS <14, the address space is strictly limited to 8 GiB, or 33 bits.
As a result, the page allocator also assumes all heap memory lives in
this region. This is especially necessary because the page allocator has
a PROT_NONE mapping proportional to the size of the usable address
space, so this keeps that mapping very small.

However starting with iOS 14, this restriction is relaxed, and mmap may
start returning addresses outside of the <14 range. Today this means
that in iOS 14 and later, users experience an error in the page
allocator when a heap arena is mapped outside of the old range.

This change increases the ios/arm64 heapAddrBits to 40 while
simultaneously making ios/arm64 use the 64-bit pagealloc implementation
(with reservations and incremental mapping) to accommodate both iOS
versions <14 and 14+.

Once iOS <14 is deprecated, we can remove these exceptions and treat
ios/arm64 like any other arm64 platform.

This change also makes the BaseChunkIdx expression a little bit easier
to read, while we're here.

For #46860.
Fixes #48115.

281860c4fe [release-branch.go1.16] runtime/race: rebuild darwin syso to work around macOS 12 malloc reserved address
On macOS 12 a new malloc implementation (nano) is used by default,
and apparently it reserves address range
0x600000000000-0x600020000000, which conflicts with the address
range that TSAN uses for Go. Work around the issue by changing the
address range slightly.

The actual change is made on LLVM at https://reviews.llvm.org/D114825 .
This CL includes syso's built with the patch applied.

The syso in 1.16 was identical to the syso before the equivalent fix
on the main branch, so the back-ported syso is identical to the fixed
syso on the main branch.

Fixes #50072.
Updates #49138.

99950270f3 [release-branch.go1.16] syscall: avoid writing to p when Pipe(p) fails
Generally speaking Go functions make no guarantees
about what has happened to result parameters on error,
and Pipe is no exception: callers should avoid looking at
p if Pipe returns an error.

However, we had a bug in which ForkExec was using the
content of p after a failed Pipe, and others may too.
As a robustness fix, make Pipe avoid writing to p on failure.

Cancelling the context in Response.Body.Read interferes with the

from not canceling the context is minor (the context timer leaks

f2b0149e57 [release-branch.go1.16] runtime: keep //go:cgo_unsafe_args arguments alive to prevent GC
When syscall's DLL.FindProc calls into syscall_getprocaddress with a
byte slice pointer, we need to keep those bytes alive. Otherwise the GC
will collect the allocation, and we wind up calling `GetProcAddress` on
garbage, which showed up as various flakes in the builders. It turns out
that this problem extends to many uses of //go:cgo_unsafe_args
throughout, on all platforms. So this patch fixes the issue by keeping
non-integer pointer arguments alive through their invocation in
//go:cgo_unsafe_args functions.

88407a8dd9 [release-branch.go1.16] archive/zip: don't panic on (*Reader).Open
Previously, opening a zip with (*Reader).Open could result in a panic if
the zip contained a file whose name was exclusively made up of slash
characters or ".." path elements.

Open could also panic if passed the empty string directly as an argument.

Now, any files in the zip whose name could not be made valid for
fs.FS.Open will be skipped, and no longer added to the fs.FS file list,
although they are still accessible through (*Reader).File.

Note that it was already the case that a file could be accessible from
(*Reader).Open with a name different from the one in (*Reader).File, as
the former is the cleaned name, while the latter is the original one.

Finally, made the actual panic site robust as a defense-in-depth measure.

900443349b [release-branch.go1.16] cmd/link: increase reserved space for passing env on wasm
On wasm, the wasm_exec.js helper passes the command line arguments and
environment variables via a reserved space in the wasm linear memory.
Increase this reserved space from 4096 to 8192 bytes so more environment
variables can fit into the limit.

Later, after https://golang.org/cl/350737 landed, we can switch to the
WASI interface for getting the arguments and environment. This would
remove the limit entirely.

8c9c148772 [release-branch.go1.16] runtime: consistently access pollDesc r/w Gs with atomics
Both netpollblock and netpollunblock read gpp using a non-atomic load.
When consuming a ready event, netpollblock clears gpp using a non-atomic
store, thus skipping a barrier.

Thus on systems with weak memory ordering, a sequence like so this is
possible:

             T1                                T2

1. netpollblock: read gpp -> pdReady
2. netpollblock: store gpp -> 0

                                 3. netpollunblock: read gpp -> pdReady
                                 4. netpollunblock: return

i.e., without a happens-before edge between (2) and (3), netpollunblock
may read the stale value of gpp.

Switch these access to use atomic loads and stores in order to create
these edges.

For ease of future maintainance, I've simply changed rg and wg to always
be accessed atomically, though I don't believe pollOpen or pollClose
require atomics today.

1a6281d950 [release-branch.go1.16] cmd/compile: ensure constant shift amounts are in range for arm
Ensure constant shift amounts are in the range [0-31]. When shift amounts
are out of range, bad things happen. Shift amounts out of range occur
when lowering 64-bit shifts (we take an in-range shift s in [0-63] and
calculate s-32 and 32-s, both of which might be out of [0-31]).

The constant shift operations themselves still work, but their shift
amounts get copied unmolested to operations like ORshiftLL which use only
the low 5 bits. That changes an operation like <<100 which unconditionally
produces 0, to <<4, which doesn't.

4548fcc8df [release-branch.go1.16] misc/wasm, cmd/link: do not let command line args overwrite global data
On Wasm, wasm_exec.js puts command line arguments at the beginning
of the linear memory (following the "zero page"). Currently there
is no limit for this, and a very long command line can overwrite
the program's data section. Prevent this by limiting the command
line to 4096 bytes, and in the linker ensuring the data section
starts at a high enough address (8192).

(Arguably our address assignment on Wasm is a bit confusing. This
is the minimum fix I can come up with.)

552410fec2 [release-branch.go1.16] runtime: in adjustTimers back up as far as necessary
When the adjustTimers function removed a timer it assumed it was
sufficient to continue the heap traversal at that position.
However, in some cases a timer will be moved to an earlier
position in the heap. If that timer is timerModifiedEarlier,
that can leave timerModifiedEarliest not correctly representing
the earlier such timer.

Fix the problem by restarting the heap traversal at the earliest
changed position.

because certain VDSO calls can modify the r30 register, which is where g
is stored. This change was reverted for PowerPC because r30 is supposed
to be a non-volatile register. This is true, but that only makes a
guarantee across function calls, but not "within" a function call. This
patch was seemingly fine before because the Linux kernel still had hand
rolled assembly VDSO function calls, however with a recent change to C
function calls it seems the compiler used can generate instructions
which temporarily clobber r30. This means that when we receive a signal
during one of these calls the value of r30 will not be the g as the
runtime expects, causing a segfault.

You can see from this assembly dump how the register is clobbered during
the call:

(the following is from a 5.13rc2 kernel)

```

```

What I believe is happening is that the kernel changed the PowerPC VDSO
calls to use standard C calls instead of using hand rolled assembly. The
hand rolled assembly calls never touched r30, so this change was safe to
roll back. That does not seem to be the case anymore as on the 5.13rc2
kernel the compiler *is* generating assembly which modifies r30, making
this change again unsafe and causing a crash when the program receives a
signal during these calls (which will happen often due to async
preempt). This change happened here:

I realize this was reverted due to unexplained hangs in PowerPC
builders, but I think we should reinstate this change and investigate
those issues separately:

On ARM64, (external) linker generated trampoline may clobber R16

3d5afa9610 [release-branch.go1.16] cmd/{compile,link}: fix bug in map.zero handling
In CL 326211 a change was made to switch "go.map.zero" symbols from
non-pkg DUPOK symbols to hashed symbols. The intent of this change was
ensure that in cases where there are multiple competing go.map.zero
symbols feeding into a link, the largest map.zero symbol is selected.
The change was buggy, however, and resulted in duplicate symbols in
the final binary (see bug cited below for details). This duplication
was relatively benign for linux/ELF, but causes duplicate definition
errors on Windows.

This patch switches "go.map.zero" symbols back from hashed symbols to
non-pkg DUPOK symbols, and updates the relevant code in the loader to
ensure that we do the right thing when there are multiple competing
DUPOK symbols with different sizes.

Fixes #47289.

ae7943e11b [release-branch.go1.16] runtime: remove adjustTimers counter
In CL 336432 we changed adjusttimers so that it no longer cleared
timerModifiedEarliest if there were no timersModifiedEarlier timers.
This caused some Google internal tests to time out, presumably due
to the increased contention on timersLock.  We can avoid that by
simply not skipping the loop in adjusttimers, which lets us safely
clear timerModifiedEarliest.  And if we don't skip the loop, then there
isn't much reason to keep the count of timerModifiedEarlier timers at all.
So remove it.

The effect will be that for programs that create some timerModifiedEarlier
timers and then remove them all, the program will do an occasional
additional loop over all the timers.  And, programs that have some
timerModifiedEarlier timers will always loop over all the timers,
without the quicker exit when they have all been seen.  But the loops
should not occur all that often, due to timerModifiedEarliest.

d4ee0255f2 [release-branch.go1.16] cmd/compile: make map.zero symbol content-addressable
The compiler machinery that generates "map.zero" symbols marks them as
RODATA and DUPOK, which is problematic when a given application has
multiple map zero symbols (from different packages) with varying
sizes: the dupok path in the loader assumes that if two symbols have
the same name, it is safe to pick any of the versions. In the case of
map.zero, the link needs to select the largest symbol, not an
arbitrary sym.

To fix this problem, mark map.zero symbols as content-addressable,
since the loader's content addressability processing path already
supports selection of the larger symbol in cases where there are dups.

Fixes #46657.

c9f27b8d31 [release-branch.go1.16] cmd/go: use a real Go version in the go.mod files in TestScript/mod_readonly
For some reason, the go.mod file added to this test in CL 147281 lists
'go 1.20' instead of the version that was actually current when the
go.mod file was added.

That causes the test's behavior to change under lazy loading, because
1.20 is above the threshold to trigger lazy-loading invariants (1.17).

This backports CL 314049 to Go 1.16 in order to fix a spurious test
failure in a subsequent change.

dbf69b7da4 [release-branch.go1.16] cmd/go: in 'go mod download' without args, don't save module zip sums
'go mod download' without arguments is frequently used to populate the
module cache. It tends to fetch a lot of extra files (for modules in
the build list that aren't needed to build packages in the main
module). It's annoying when sums are written for these extra files.

'go mod download mod@version' will still write sums for specific
modules in the build list. 'go mod download all' still has the
previous behavior.

For now, all invocations of 'go mod download' still update go.mod and
go.sum with changes needed to load the build list (1.15 behavior).

40b97d6921 [release-branch.go1.16] cmd/link/internal: fix use of DynlinkingGo with ppc64le trampolines
When creating programs with large text sections on ppc64le,
trampolines are needed for calls that are too far; however
they are not created if the code is generated such that the TOC
register r2 is initialized and maintained in the code because
then the external linker can create the trampolines. Previously
the function DynlinkingGo was used to determine this but in the
case where plugins are used, this could return true even though
r2 is not valid.

To fix this problem I've added a new function r2Valid which returns
true when the build options indicate that the r2 is
initialized and maintained. Because of the ways that
DynlinkingGo is used I wanted to maintain its previous
behavior.

ce04f86bd3 [release-branch.go1.16] syscall: syscall.AllThreadsSyscall signal handling fixes
The runtime support for syscall.AllThreadsSyscall() functions had
some corner case deadlock issues when signal handling was in use.
This was observed in at least 3 build test failures on ppc64 and
amd64 architecture CGO_ENABLED=0 builds over the last few months.

The fixes involve more controlled handling of signals while the
AllThreads mechanism is being executed. Further details are
discussed in bug #44193.

The all-threads syscall support is new in go1.16, so earlier
releases are not affected by this bug.

f12cf7694f [release-branch.go1.16] time: use offset and isDST when caching zone from extend string
If the current time is computed from extend string
and the zone file contains multiple zones with the
same name, the lookup by name might find incorrect
zone.

This happens for example with the slim Europe/Dublin
time zone file in the embedded zip. This zone file
has last transition in 1996 and rest is covered by
extend string.
tzset returns IST as the zone name to use, but there
are two records with IST name. Lookup by name finds
the wrong one. We need to check offset and isDST too.

In case we can't find an existing zone, we allocate
a new zone so that we use correct offset and isDST.

I have renamed zone variable to zones as it shadowed
the zone type that we need to allocate the cached zone.

Backport note: this change also incorporates portions of
CL 264077.

96139f2599 [release-branch.go1.16] cmd/compile: fix long RMW bit operations on AMD64
Under certain circumstances, the existing rules for bit operations can
produce code that writes beyond its intended bounds. For example,
consider the following code:

    func repro(b []byte, addr, bit int32) {
	    _ = b[3]
	    v := uint32(b[0]) | uint32(b[1])<<8 | uint32(b[2])<<16 | uint32(b[3])<<24 | 1<<(bit&31)
	    b[0] = byte(v)
	    b[1] = byte(v >> 8)
	    b[2] = byte(v >> 16)
	    b[3] = byte(v >> 24)
    }

Roughly speaking:

1. The expression `1 << (bit & 31)` is rewritten into `(SHLL 1 bit)`
2. The expression `uint32(b[0]) | uint32(b[1])<<8 | uint32(b[2])<<16 |
   uint32(b[3])<<24` is rewritten into `(MOVLload &b[0])`
3. The statements `b[0] = byte(v) ... b[3] = byte(v >> 24)` are
   rewritten into `(MOVLstore &b[0], v)`
4. `(ORL (SHLL 1, bit) (MOVLload &b[0]))` is rewritten into
   `(BTSL (MOVLload &b[0]) bit)`. This is a valid transformation because
   the destination is a register: in this case, the bit offset is masked
   by the number of bits in the destination register. This is identical
   to the masking performed by `SHL`.
5. `(MOVLstore &b[0] (BTSL (MOVLload &b[0]) bit))` is rewritten into
   `(BTSLmodify &b[0] bit)`. This is an invalid transformation because
   the destination is memory: in this case, the bit offset is not
   masked, and the chosen instruction may write outside its intended
   32-bit location.

These changes fix the invalid rewrite performed in step (5) by
explicitly maksing the bit offset operand to `BT(S|R|C)(L|Q)modify`. In
the example above, the adjusted rules produce
`(BTSLmodify &b[0] (ANDLconst [31] bit))` in step (5).

These changes also add several new rules to rewrite bit sets, toggles,
and clears that are rooted at `(OR|XOR|AND)(L|Q)modify` operators into
appropriate `BT(S|R|C)(L|Q)modify` operators. These rules catch cases
where `MOV(L|Q)store ((OR|XOR|AND)(L|Q) ...)` is rewritten to
`(OR|XOR|AND)(L|Q)modify` before the `(OR|XOR|AND)(L|Q) ...` can be
rewritten to `BT(S|R|C)(L|Q) ...`.

Overall, compilecmp reports small improvements in code size on

887c0d890f [release-branch.go1.16] runtime: non-strict InlTreeIndex lookup in Frames.Next
When using cgo, some of the frames can be provided by cgoTraceback, a
cgo-provided function to generate C tracebacks. Unlike Go tracebacks,
cgoTraceback has no particular guarantees that it produces valid
tracebacks.

If one of the (invalid) frames happens to put the PC in the alignment
region at the end of a function (filled with int 3's on amd64), then
Frames.Next will find a valid funcInfo for the PC, but pcdatavalue will
panic because PCDATA doesn't cover this PC.

Tolerate this case by doing a non-strict PCDATA lookup. We'll still show
a bogus frame, but at least avoid throwing.

3a45c13094 [release-branch.go1.16] cmd/compile: disable shortcircuit optimization for intertwined phi values
We need to be careful that when doing value graph surgery, we not
re-substitute a value that has already been substituted. That can lead
to confusing a previous iteration's value with the current iteration's
value.

The simple fix in this CL just aborts the optimization if it detects
intertwined phis (a phi which is the argument to another phi). It
might be possible to keep the optimization with a more complicated
CL, but:
  1) This CL is clearly safe to backport.
  2) There were no instances of this abort triggering in
     all.bash, prior to the test introduced in this CL.

Fixes #45192

1d967ab95c [release-branch.go1.16] build: set GOPATH consistently in run.bash, run.bat, run.rc
We used to clear GOPATH in all the build scripts.
Clearing GOPATH is misleading at best, since you just end up
with the default GOPATH (%USERPROFILE%\go on Windows).
Unless that's your GOROOT, in which case you end up with a
fatal error from the go command (#43938).

run.bash changed to setting GOPATH=/dev/null, which has no
clear analogue on Windows.

run.rc still clears GOPATH.

Change them all to set GOPATH to a non-existent directory
/nonexist-gopath or c:\nonexist-gopath.

9c7463ca90 [release-branch.go1.16] cmd/link: generate trampoline for inter-dependent packages
Currently, in the trampoline generation pass we expect packages
are laid out in dependency order, so a cross-package jump always
has a known target address so we can check if a trampoline is
needed. With linknames, there can be cycles in the package
dependency graph, making this algorithm no longer work. For them,
as the target address is unkown we conservatively generate a
trampoline. This may generate unnecessary trampolines (if the
packages turn out laid together), but package cycles are extremely
rare so this is fine.

Updates #44639.
Fixes #44640.

33fb47921f [release-branch.go1.16] cmd/go/internal/modfetch: detect and recover from missing ziphash file
Previously, if an extracted module directory existed in the module
cache, but the corresponding ziphash file did not, if the sum was
missing from go.sum, we would not verify the sum. This caused 'go get'
not to write missing sums. 'go build' in readonly mode (now the
default) checks for missing sums and doesn't attempt to fetch modules
that can't be verified against go.sum.

With this change, when requesting the module directory with
modfetch.DownloadDir, if the ziphash file is missing, the go command
will re-hash the zip without downloading or re-extracting it again.

Note that the go command creates the ziphash file before the module
directory, but another program could remove it separately, and it
might not be present after a crash.

0da04a662a [release-branch.go1.16] runtime, time: disable preemption in addtimer
The timerpMask optimization updates a mask of Ps (potentially)
containing timers in pidleget / pidleput. For correctness, it depends on
the assumption that new timers can only be added to a P's own heap.

addtimer violates this assumption if it is preempted after computing pp.
That G may then run on a different P, but adding a timer to the original
P's heap.

Avoid this by disabling preemption while pp is in use.

Other uses of doaddtimer should be OK:

* moveTimers: always moves to the current P's heap
* modtimer, cleantimers, addAdjustedTimers, runtimer: does not add net
  new timers to the heap while locked

When using plugins, a type (whose value) may be pass to a plugin
and get converted to interface there, or vice versa. We need to
treat the type as potentially converted to interface, and retain
its methods.

292abd96ae [release-branch.go1.16] cmd/compile: fix escape analysis of heap-allocated results
One of escape analysis's responsibilities is to summarize whether/how
each function parameter flows to the heap so we can correctly
incorporate those flows into callers' escape analysis data flow
graphs.

As an optimization, we separately record when parameters flow to
result parameters, so that we can more precisely analyze parameter
flows based on how the results are used at the call site. However, if
a named result parameter itself needs to be heap allocated, this
optimization isn't safe and the parameter needs to be recorded as
flowing to heap rather than flowing to result.

Escape analysis used to get this correct because it conservatively
rewalked the data-flow graph multiple times. So even though it would
incorrectly record the result parameter flow, it would separately find
a flow to the heap. However, CL 196811 (specifically, case 3)
optimized the walking logic to reduce unnecessary rewalks causing us
to stop finding the extra heap flow.

This CL fixes the issue by correcting location.leakTo to be sensitive
to sink.escapes and not record result-flows when the result parameter
escapes to the heap.

Fixes #44659.

88f91b709e [release-branch.go1.16] time: correct unusual extension string cases
This fixes two uncommon cases.

First, the tzdata code permits timezone offsets up to 24 * 7, although
the POSIX TZ parsing does not. The tzdata code uses this to specify a
day of week in some cases.

Second, we incorrectly rejected a negative time offset for when a time
zone change comes into effect.

4fd2617cd8 [release-branch.go1.16] syscall: do not overflow key memory in GetQueuedCompletionStatus
The third argument to GetQueuedCompletionStatus is a pointer to a
uintptr, not a uint32. Users of this functions have therefore been
corrupting their memory every time they used it. Either that memory
corruption was silent (dangerous), or their programs didn't work so they
chose a different API to use.

This fixes the problem by passing through an intermediate buffer.

ca9cd629fb [release-branch.go1.16] cmd/compile: fix mishandling of unsafe-uintptr arguments with call method in go/defer
In CL 253457, we did the same fix for direct function calls. But for
method calls, the receiver argument also need to be passed through the
wrapper function, which we are not doing so the compiler crashes with
the code in #44415.

It will be nicer if we can rewrite OCALLMETHOD to normal OCALLFUNC, but
that will be for future CL. The passing receiver argument to wrapper
function is easier for backporting to go1.16 branch.

18e5d75ffb [release-branch.go1.16] cmd/compile: fix panic in DWARF-gen handling obfuscated code
DWARF generation uses variable source positions (file/line/col) as a
way to uniquely identify locals and parameters, as part of the process
of matching up post-optimization variables with the corresponding
pre-optimization versions (since the DWARF needs to be in terms of the
original source constructs).

This strategy can run into problems when compiling obfuscated or
machine-generated code, where you can in some circumstances wind up
with two local variables that appear to have the same name, file,
line, and column. This patch changes DWARF generation to skip over
such duplicates as opposed to issuing a fatal error (if an
obfuscation tool is in use, it is unlikely that a human being will be
able to make much sense of DWARF info in any case).

Fixes #44433.

ddeae6b248 [release-branch.go1.16] cmd/compile: declare inlined result params early for empty returns
The code for delayed declaration of inlined result parameters only
handles non-empty return statements. This is generally okay, because
we already early declare if there are any (non-blank) named result
parameters.

But if a user writes a function with only blank result parameters and
with exactly one return statement, which is empty, then they could end
up hitting the dreaded "Value live at entry" ICE.

This CL fixes the issue by ensuring we always early declare inlined
result parameters if there are any empty return statements.

Fixes #44358.

936829eff4 [dev.boringcrypto.go1.16] all: branch dev.boringcrypto.go1.16
We don't set a parent-branch because we can't use "git-codereview
sync-branch" to do our merges since we want them to happen at a specific
commit (the release tag), not at the HEAD of the release-branch.

We have misc/boring/merge.sh for release merges.

To be fair, we can't use it for dev.boringcrypto merges either, because
those also need to happen at the first conflicting commit, not at HEAD,
but I am hoping eventually we'll get release merges into the release
process, and maybe add a flag to sync-branch for master merges.

### What is the path of the package that you would like to have removed?
<!---
We can remove packages with a shared path prefix.
For example, a request for "github.com/author" would remove all pkg.go.dev pages with that package path prefix.
--->
### Are you the owner of this package?
<!---
Only the package owners can request to have their packages removed from pkg.go.dev.
--->
### What is the reason that you could not retract this package instead?
<!---
If you would like to have your module removed from pkg.go.dev, we recommend that you retract them, so that they can be removed from the go command and proxy.golang.org as well.
Retracting a module version involves adding a retract directive to your go.mod file and publishing a new version. For example: https://github.com/jba/retract-demo/blob/main/go.mod#L5-L8
See https://pkg.go.dev/about#removing-a-package for additional tips on retractions.

### Author background
- **Would you consider yourself a novice, intermediate, or experienced Go programmer?**
- **What other languages do you have experience with?**
### Related proposals
- **Has this idea, or one like it, been proposed before?**
- **If so, how does this proposal differ?**
- **Does this affect error handling?**
- **If so, how does this differ from previous error handling proposals?**
- **Is this about generics?**
- **If so, how does this relate to the accepted design and other generics proposals?**
### Proposal
- **What is the proposed change?**
- **Who does this proposal help, and why?**
- **Please describe as precisely as possible the change to the language.**
- **What would change in the language spec?**
- **Please also describe the change informally, as in a class teaching Go.**
- **Is this change backward compatible?**
- Breaking the Go 1 compatibility guarantee is a large cost and requires a large benefit.
Show example code before and after the change.
- **Before**
- **After**
- **Orthogonality: how does this change interact or overlap with existing features?**
- **Is the goal of this change a performance improvement?**
- **If so, what quantifiable improvement should we expect?**
- **How would we measure it?**
### Costs
- **Would this change make Go easier or harder to learn, and why?**
- **What is the cost of this proposal? (Every language change has a cost).**
- **How many tools (such as vet, gopls, gofmt, goimports, etc.) would be affected?**
- **What is the compile time cost?**
- **What is the run time cost?**
- **Can you describe a possible implementation?**
- **Do you have a prototype? (This is not required.)**

# dev.boringcrypto branch
We have been working inside Google on a fork of Go that uses
BoringCrypto (the core of [BoringSSL][]) for various crypto
primitives, in furtherance of some [work related to FIPS 140-2][sp].
We have heard that some external users of Go would be interested in
this code as well, so this branch holds the patches to make Go use
BoringCrypto.
[BoringSSL]: https://boringssl.googlesource.com/boringssl/
[sp]: https://csrc.nist.gov/CSRC/media/projects/cryptographic-module-validation-program/documents/security-policies/140sp3678.pdf
Unlike typical dev branches, we do not intend any eventual merge of
this code into the master branch. Instead we intend to maintain in
this branch the latest release plus BoringCrypto patches.
To be clear, we are not making any statements or representations about
the suitability of this code in relation to the FIPS 140-2 standard.
Interested users will have to evaluate for themselves whether the code
is useful for their own purposes.

except.txt lists features that may disappear without breaking true
compatibility.
Starting with go1.19.txt, each API feature line must end in "#nnnnn"
giving the GitHub issue number of the proposal issue that accepted
the new API. This helps with our end-of-cycle audit of new APIs.
The same requirement applies to next/* (described below), which will
become a go1.XX.txt for XX >= 19.
The next/ directory contains the only files intended to be mutated.
Each file in that directory contains a list of features that may be added
to the next release of Go. The files in this directory only affect the
warning output from the go api tool. Each file should be named
nnnnn.txt, after the issue number for the accepted proposal.
(The #nnnnn suffix must also appear at the end of each line in the file;
that will be preserved when next/*.txt is concatenated into go1.XX.txt.)
next.txt is the only file intended to be mutated. It's a list of
features that may be added to the next version. It only affects

aiming to keep the semantics simple, understandable, and useful.
This section gives a general overview of the approach and should suffice for most programmers.
The memory model is specified more formally in the next section.
Within a single goroutine, reads and writes must behave
as if they executed in the order specified by the program.
That is, compilers and processors may reorder the reads and writes
executed within a single goroutine only when the reordering
does not change the behavior within that goroutine
as defined by the language specification.
Because of this reordering, the execution order observed
by one goroutine may differ from the order perceived
by another. For example, if one goroutine
executes <code>a = 1; b = 2;</code>, another might observe
the updated value of <code>b</code> before the updated value of <code>a</code>.
</p>
<p>
A <em>data race</em> is defined as
a write to a memory location happening concurrently with another read or write to that same location,
unless all the accesses involved are atomic data accesses as provided by the <code>sync/atomic</code> package.
As noted already, programmers are strongly encouraged to use appropriate synchronization
to avoid data races.
In the absence of data races, Go programs behave as if all the goroutines
were multiplexed onto a single processor.
This property is sometimes referred to as DRF-SC: data-race-free programs
execute in a sequentially consistent manner.
To specify the requirements of reads and writes, we define
<i>happens before</i>, a partial order on the execution
of memory operations in a Go program. If event <span class="event">e<sub>1</sub></span> happens
before event <span class="event">e<sub>2</sub></span>, then we say that <span class="event">e<sub>2</sub></span> happens after <span class="event">e<sub>1</sub></span>.
Also, if <span class="event">e<sub>1</sub></span> does not happen before <span class="event">e<sub>2</sub></span> and does not happen
after <span class="event">e<sub>2</sub></span>, then we say that <span class="event">e<sub>1</sub></span> and <span class="event">e<sub>2</sub></span> happen concurrently.
</p>
<p class="rule">
Within a single goroutine, the happens-before order is the
order expressed by the program.
</p>
<p>
While programmers should write Go programs without data races,
there are limitations to what a Go implementation can do in response to a data race.
An implementation may always react to a data race by reporting the race and terminating the program.
Otherwise, each read of a single-word-sized or sub-word-sized memory location
must observe a value actually written to that location (perhaps by a concurrent executing goroutine)
and not yet overwritten.
These implementation constraints make Go more like Java or JavaScript,
in that most races have a limited number of outcomes,
and less like C and C++, where the meaning of any program with a race
is entirely undefined, and the compiler may do anything at all.
Go's approach aims to make errant programs more reliable and easier to debug,
while still insisting that races are errors and that tools can diagnose and report them.
A read <span class="event">r</span> of a variable <code>v</code> is <i>allowed</i> to observe a write <span class="event">w</span> to <code>v</code>
if both of the following hold:
</p>
<h2 id="model">Memory Model</h2>
<p>
The following formal definition of Go's memory model closely follows
the approach presented by Hans-J. Boehm and Sarita V. Adve in
<a href="https://www.hpl.hp.com/techreports/2008/HPL-2008-56.pdf">Foundations of the C++ Concurrency Memory Model</a>”,
published in PLDI 2008.
The definition of data-race-free programs and the guarantee of sequential consistency
for race-free programs are equivalent to the ones in that work.
</p>
<p>
The memory model describes the requirements on program executions,
which are made up of goroutine executions,
which in turn are made up of memory operations.
</p>
<p>
A <i>memory operation</i> is modeled by four details:
</p>
<ul>
<li>its kind, indicating whether it is an ordinary data read, an ordinary data write,
or a <i>synchronizing operation</i> such as an atomic data access,
a mutex operation, or a channel operation,
<li>its location in the program,
<li>the memory location or variable being accessed, and
<li>the values read or written by the operation.
</ul>
<p>
Some memory operations are <i>read-like</i>, including read, atomic read, mutex lock, and channel receive.
Other memory operations are <i>write-like</i>, including write, atomic write, mutex unlock, channel send, and channel close.
Some, such as atomic compare-and-swap, are both read-like and write-like.
</p>
<p>
A <i>goroutine execution</i> is modeled as a set of memory operations executed by a single goroutine.
</p>
<p>
<b>Requirement 1</b>:
The memory operations in each goroutine must correspond to a correct sequential execution of that goroutine,
given the values read from and written to memory.
That execution must be consistent with the <i>sequenced before</i> relation,
defined as the partial order requirements set out by the <a href="/ref/spec">Go language specification</a>
for Go's control flow constructs as well as the <a href="/ref/spec#Order_of_evaluation">order of evaluation for expressions</a>.
</p>
<p>
A Go <i>program execution</i> is modeled as a set of goroutine executions,
together with a mapping <i>W</i> that specifies the write-like operation that each read-like operation reads from.
(Multiple executions of the same program can have different program executions.)
</p>
<p>
<b>Requirement 2</b>:
For a given program execution, the mapping <i>W</i>, when limited to synchronizing operations,
must be explainable by some implicit total order of the synchronizing operations
that is consistent with sequencing and the values read and written by those operations.
</p>
<p>
The <i>synchronized before</i> relation is a partial order on synchronizing memory operations,
derived from <i>W</i>.
If a synchronizing read-like memory operation <i>r</i>
observes a synchronizing write-like memory operation <i>w</i>
(that is, if <i>W</i>(<i>r</i>) = <i>w</i>),
then <i>w</i> is synchronized before <i>r</i>.
Informally, the synchronized before relation is a subset of the implied total order
mentioned in the previous paragraph,
limited to the information that <i>W</i> directly observes.
</p>
<p>
The <i>happens before</i> relation is defined as the transitive closure of the
union of the sequenced before and synchronized before relations.
</p>
<p>
<b>Requirement 3</b>:
For an ordinary (non-synchronizing) data read <i>r</i> on a memory location <i>x</i>,
<i>W</i>(<i>r</i>) must be a write <i>w</i> that is <i>visible</i> to <i>r</i>,
where visible means that both of the following hold:
<ol>
<li><i>w</i> happens before <i>r</i>.
<li><i>w</i> does not happen before any other write <i>w'</i> (to <i>x</i>) that happens before <i>r</i>.
<li><span class="event">r</span> does not happen before <span class="event">w</span>.</li>
<li>There is no other write <span class="event">w'</span> to <code>v</code> that happens
after <span class="event">w</span> but before <span class="event">r</span>.</li>
</ol>
<p>
A <i>read-write data race</i> on memory location <i>x</i>
consists of a read-like memory operation <i>r</i> on <i>x</i>
and a write-like memory operation <i>w</i> on <i>x</i>,
at least one of which is non-synchronizing,
which are unordered by happens before
(that is, neither <i>r</i> happens before <i>w</i>
nor <i>w</i> happens before <i>r</i>).
To guarantee that a read <span class="event">r</span> of a variable <code>v</code> observes a
particular write <span class="event">w</span> to <code>v</code>, ensure that <span class="event">w</span> is the only
write <span class="event">r</span> is allowed to observe.
That is, <span class="event">r</span> is <i>guaranteed</i> to observe <span class="event">w</span> if both of the following hold:
</p>
<ol>
<li><span class="event">w</span> happens before <span class="event">r</span>.</li>
<li>Any other write to the shared variable <code>v</code>
either happens before <span class="event">w</span> or after <span class="event">r</span>.</li>
</ol>
<p>
This pair of conditions is stronger than the first pair;
it requires that there are no other writes happening
concurrently with <span class="event">w</span> or <span class="event">r</span>.
</p>
<p>
A <i>write-write data race</i> on memory location <i>x</i>
consists of two write-like memory operations <i>w</i> and <i>w'</i> on <i>x</i>,
at least one of which is non-synchronizing,
which are unordered by happens before.
Within a single goroutine,
there is no concurrency, so the two definitions are equivalent:
a read <span class="event">r</span> observes the value written by the most recent write <span class="event">w</span> to <code>v</code>.
When multiple goroutines access a shared variable <code>v</code>,
they must use synchronization events to establish
happens-before conditions that ensure reads observe the
desired writes.
</p>
<p>
Note that if there are no read-write or write-write data races on memory location <i>x</i>,
then any read <i>r</i> on <i>x</i> has only one possible <i>W</i>(<i>r</i>):
the single <i>w</i> that immediately precedes it in the happens before order.
The initialization of variable <code>v</code> with the zero value
for <code>v</code>'s type behaves as a write in the memory model.
</p>
<p>
More generally, it can be shown that any Go program that is data-race-free,
meaning it has no program executions with read-write or write-write data races,
can only have outcomes explained by some sequentially consistent interleaving
of the goroutine executions.
(The proof is the same as Section 7 of Boehm and Adve's paper cited above.)
This property is called DRF-SC.
Reads and writes of values larger than a single machine word
behave as multiple machine-word-sized operations in an
unspecified order.
</p>
<p>
The intent of the formal definition is to match
the DRF-SC guarantee provided to race-free programs
by other languages, including C, C++, Java, JavaScript, Rust, and Swift.
</p>
<h2>Synchronization</h2>
<p>
Certain Go language operations such as goroutine creation and memory allocation
act as synchronization operations.
The effect of these operations on the synchronized-before partial order
is documented in the “Synchronization” section below.
Individual packages are responsible for providing similar documentation
for their own operations.
</p>
<h2 id="restrictions">Implementation Restrictions for Programs Containing Data Races</h2>
<p>
The preceding section gave a formal definition of data-race-free program execution.
This section informally describes the semantics that implementations must provide
for programs that do contain races.
</p>
<p>
First, any implementation can, upon detecting a data race,
report the race and halt execution of the program.
Implementations using ThreadSanitizer
(accessed with “<code>go</code> <code>build</code> <code>-race</code>”)
do exactly this.
</p>
<p>
Otherwise, a read <i>r</i> of a memory location <i>x</i>
that is not larger than a machine word must observe
some write <i>w</i> such that <i>r</i> does not happen before <i>w</i>
and there is no write <i>w'</i> such that <i>w</i> happens before <i>w'</i>
and <i>w'</i> happens before <i>r</i>.
That is, each read must observe a value written by a preceding or concurrent write.
</p>
<p>
Additionally, observation of acausal and “out of thin air” writes is disallowed.
</p>
<p>
Reads of memory locations larger than a single machine word
are encouraged but not required to meet the same semantics
as word-sized memory locations,
observing a single allowed write <i>w</i>.
For performance reasons,
implementations may instead treat larger operations
as a set of individual machine-word-sized operations
in an unspecified order.
This means that races on multiword data structures
can lead to inconsistent values not corresponding to a single write.
When the values depend on the consistency
of internal (pointer, length) or (pointer, type) pairs,
as can be the case for interface values, maps,
slices, and strings in most Go implementations,
such races can in turn lead to arbitrary memory corruption.

<p>
The Go memory model restricts compiler optimizations as much as it does Go programs.
Some compiler optimizations that would be valid in single-threaded programs are not valid in all Go programs.
In particular, a compiler must not introduce writes that do not exist in the original program,
it must not allow a single read to observe multiple values,
and it must not allow a single write to write multiple values.
</p>
<p>
All the following examples assume that `*p` and `*q` refer to
memory locations accessible to multiple goroutines.
</p>
<p>
Not introducing data races into race-free programs means not moving
writes out of conditional statements in which they appear.
For example, a compiler must not invert the conditional in this program:
</p>
<pre>
*p = 1
if cond {
*p = 2
}
</pre>
<p>
That is, the compiler must not rewrite the program into this one:
</p>
<pre>
*p = 2
if !cond {
*p = 1
}
</pre>
<p>
If <code>cond</code> is false and another goroutine is reading <code>*p</code>,
then in the original program, the other goroutine can only observe any prior value of <code>*p</code> and <code>1</code>.
In the rewritten program, the other goroutine can observe <code>2</code>, which was previously impossible.
</p>
<p>
Not introducing data races also means not assuming that loops terminate.
For example, a compiler must in general not move the accesses to <code>*p</code> or <code>*q</code>
ahead of the loop in this program:
</p>
<pre>
n := 0
for e := list; e != nil; e = e.next {
n++
}
i := *p
*q = 1
</pre>
<p>
If <code>list</code> pointed to a cyclic list,
then the original program would never access <code>*p</code> or <code>*q</code>,
but the rewritten program would.
(Moving `*p` ahead would be safe if the compiler can prove `*p` will not panic;
moving `*q` ahead would also require the compiler proving that no other
goroutine can access `*q`.)
</p>
<p>
Not introducing data races also means not assuming that called functions
always return or are free of synchronization operations.
For example, a compiler must not move the accesses to <code>*p</code> or <code>*q</code>
ahead of the function call in this program
(at least not without direct knowledge of the precise behavior of <code>f</code>):
</p>
<pre>
f()
i := *p
*q = 1
</pre>
<p>
If the call never returned, then once again the original program
would never access <code>*p</code> or <code>*q</code>, but the rewritten program would.
And if the call contained synchronizing operations, then the original program
could establish happens before edges preceding the accesses
to <code>*p</code> and <code>*q</code>, but the rewritten program would not.
</p>
<p>
Not allowing a single read to observe multiple values means
not reloading local variables from shared memory.
For example, a compiler must not discard <code>i</code> and reload it
a second time from <code>*p</code> in this program:
</p>
<pre>
i := *p
if i &lt; 0 || i &gt;= len(funcs) {
panic("invalid function index")
}
... complex code ...
// compiler must NOT reload i = *p here
funcs[i]()
</pre>
<p>
If the complex code needs many registers, a compiler for single-threaded programs
could discard <code>i</code> without saving a copy and then reload
<code>i = *p</code> just before
<code>funcs[i]()</code>.
A Go compiler must not, because the value of <code>*p</code> may have changed.
(Instead, the compiler could spill <code>i</code> to the stack.)
</p>
<p>
Not allowing a single write to write multiple values also means not using
the memory where a local variable will be written as temporary storage before the write.
For example, a compiler must not use <code>*p</code> as temporary storage in this program:
</p>
<pre>
*p = i + *p/2
</pre>
<p>
That is, it must not rewrite the program into this one:
</p>
<pre>
*p /= 2
*p += i
</pre>
<p>
If <code>i</code> and <code>*p</code> start equal to 2,
the original code does <code>*p = 3</code>,
so a racing thread can read only 2 or 3 from <code>*p</code>.
The rewritten code does <code>*p = 1</code> and then <code>*p = 3</code>,
allowing a racing thread to read 1 as well.
</p>
<p>
Note that all these optimizations are permitted in C/C++ compilers:
a Go compiler sharing a back end with a C/C++ compiler must take care
to disable optimizations that are invalid for Go.
</p>
<p>
Note that the prohibition on introducing data races
does not apply if the compiler can prove that the races
do not affect correct execution on the target platform.
For example, on essentially all CPUs, it is valid to rewrite
</p>
<pre>
n := 0
for i := 0; i < m; i++ {
n += *shared
}
</pre>
into:
<pre>
n := 0
local := *shared
for i := 0; i < m; i++ {
n += local
}
</pre>
<p>
provided it can be proved that <code>*shared</code> will not fault on access,
because the potential added read will not affect any existing concurrent reads or writes.
On the other hand, the rewrite would not be valid in a source-to-source translator.
</p>
<h2 id="conclusion">Conclusion</h2>
<p>
Go programmers writing data-race-free programs can rely on
sequentially consistent execution of those programs,
just as in essentially all other modern programming languages.
</p>
<p>
When it comes to programs with races,
both programmers and compilers should remember the advice:
don't be clever.

title: "Go, Backwards Compatibility, and GODEBUG"
layout: article
---
<!--
This document is kept in the Go repo, not x/website,
because it documents the full list of known GODEBUG settings,
which are tied to a specific release.
-->
## Introduction {#intro}
Go's emphasis on backwards compatibility is one of its key strengths.
There are, however, times when we cannot maintain complete compatibility.
If code depends on buggy (including insecure) behavior,
then fixing the bug will break that code.
New features can also have similar impacts:
enabling the HTTP/2 use by the HTTP client broke programs
connecting to servers with buggy HTTP/2 implementations.
These kinds of changes are unavoidable and
[permitted by the Go 1 compatibility rules](/doc/go1compat).
Even so, Go provides a mechanism called GODEBUG to
reduce the impact such changes have on Go developers
using newer toolchains to compile old code.
A GODEBUG setting is a `key=value` pair
that controls the execution of certain parts of a Go program.
The environment variable `GODEBUG`
can hold a comma-separated list of these settings.
For example, if a Go program is running in an environment that contains
GODEBUG=http2client=0,http2server=0
then that Go program will disable the use of HTTP/2 by default in both
the HTTP client and the HTTP server.
It is also possible to set the default `GODEBUG` for a given program
(discussed below).
When preparing any change that is permitted by Go 1 compatibility
but may nonetheless break some existing programs,
we first engineer the change to keep as many existing programs working as possible.
For the remaining programs,
we define a new GODEBUG setting that
allows individual programs to opt back in to the old behavior.
A GODEBUG setting may not be added if doing so is infeasible,
but that should be extremely rare.
GODEBUG settings added for compatibility will be maintained
for a minimum of two years (four Go releases).
Some, such as `http2client` and `http2server`,
will be maintained much longer, even indefinitely.
When possible, each GODEBUG setting has an associated
[runtime/metrics](/pkg/runtime/metrics/) counter
named `/godebug/non-default-behavior/<name>:events`
that counts the number of times a particular program's
behavior has changed based on a non-default value
for that setting.
For example, when `GODEBUG=http2client=0` is set,
`/godebug/non-default-behavior/http2client:events`
counts the number of HTTP transports that the program
has configured without HTTP/2 support.
## Default GODEBUG Values {#default}
When a GODEBUG setting is not listed in the environment variable,
its value is derived from three sources:
the defaults for the Go toolchain used to build the program,
amended to match the Go version listed in `go.mod`,
and then overridden by explicit `//go:debug` lines in the program.
The [GODEBUG History](#history) gives the exact defaults for each Go toolchain version.
For example, Go 1.21 introduces the `panicnil` setting,
controlling whether `panic(nil)` is allowed;
it defaults to `panicnil=0`, making `panic(nil)` a run-time error.
Using `panicnil=1` restores the behavior of Go 1.20 and earlier.
When compiling a work module or workspace that declares
an older Go version, the Go toolchain amends its defaults
to match that older Go version as closely as possible.
For example, when a Go 1.21 toolchain compiles a program,
if the work module's `go.mod` or the workspace's `go.work`
says `go` `1.20`, then the program defaults to `panicnil=1`,
matching Go 1.20 instead of Go 1.21.
Because this method of setting GODEBUG defaults was introduced only in Go 1.21,
programs listing versions of Go earlier than Go 1.20 are configured to match Go 1.20,
not the older version.
To override these defaults, a main package's source files
can include one or more `//go:debug` directives at the top of the file
(preceding the `package` statement).
Continuing the `panicnil` example, if the module or workspace is updated
to say `go` `1.21`, the program can opt back into the old `panic(nil)`
behavior by including this directive:
//go:debug panicnil=1
Starting in Go 1.21, the Go toolchain treats a `//go:debug` directive
with an unrecognized GODEBUG setting as an invalid program.
Programs with more than one `//go:debug` line for a given setting
are also treated as invalid.
(Older toolchains ignore `//go:debug` directives entirely.)
The defaults that will be compiled into a main package
are reported by the command:
{{raw `
go list -f '{{.DefaultGODEBUG}}' my/main/package
`}}
Only differences from the base Go toolchain defaults are reported.
When testing a package, `//go:debug` lines in the `*_test.go`
files are treated as directives for the test's main package.
In any other context, `//go:debug` lines are ignored by the toolchain;
`go` `vet` reports such lines as misplaced.
## GODEBUG History {#history}
This section documents the GODEBUG settings introduced and removed in each major Go release
for compatibility reasons.
Packages or programs may define additional settings for internal debugging purposes;
for example,
see the [runtime documentation](/pkg/runtime#hdr-Environment_Variables)
and the [go command documentation](/cmd/go#hdr-Build_and_test_caching).
### Go 1.21
Go 1.21 made it a run-time error to call `panic` with a nil interface value,
controlled by the [`panicnil` setting](/pkg/builtin/#panic).
Go 1.21 made it an error for html/template actions to appear inside of an ECMAScript 6
template literal, controlled by the
[`jstmpllitinterp` setting](/pkg/html/template#hdr-Security_Model).
This behavior was backported to Go 1.19.8+ and Go 1.20.3+.
Go 1.21 introduced a limit on the maximum number of MIME headers and multipart
forms, controlled by the
[`multipartmaxheaders` and `multipartmaxparts` settings](/pkg/mime/multipart#hdr-Limits)
respectively.
This behavior was backported to Go 1.19.8+ and Go 1.20.3+.
There is no plan to remove any of these settings.
### Go 1.20
Go 1.20 introduced support for rejecting insecure paths in tar and zip archives,
controlled by the [`tarinsecurepath` setting](/pkg/archive/tar/#Reader.Next)
and the [`zipinsecurepath` setting](/pkg/archive/zip/#NewReader).
These default to `tarinsecurepath=1` and `zipinsecurepath=1`,
preserving the behavior of earlier versions of Go.
A future version of Go may change the defaults to
`tarinsecurepath=0` and `zipinsecurepath=0`.
Go 1.20 introduced automatic seeding of the
[`math/rand`](/pkg/math/rand) global random number generator,
controlled by the [`randautoseed` setting](/pkg/math/rand/#Seed).
Go 1.20 introduced the concept of fallback roots for use during certificate verification,
controlled by the [`x509usefallbackroots` setting](/pkg/crypto/x509/#SetFallbackRoots).
Go 1.20 removed the preinstalled `.a` files for the standard library
from the Go distribution.
Installations now build and cache the standard library like
packages in other modules.
The [`installgoroot` setting](/cmd/go#hdr-Compile_and_install_packages_and_dependencies)
restores the installation and use of preinstalled `.a` files.
There is no plan to remove any of these settings.
### Go 1.19
Go 1.19 made it an error for path lookups to resolve to binaries in the current directory,
controlled by the [`execerrdot` setting](/pkg/os/exec#hdr-Executables_in_the_current_directory).
There is no plan to remove this setting.
### Go 1.18
Go 1.18 removed support for SHA1 in most X.509 certificates,
controlled by the [`x509sha1` setting](/crypto/x509#InsecureAlgorithmError).
This setting will be removed in a future release, Go 1.22 at the earliest.
### Go 1.10
Go 1.10 changed how build caching worked and added test caching, along
with the [`gocacheverify`, `gocachehash`, and `gocachetest` settings](/cmd/go/#hdr-Build_and_test_caching).
There is no plan to remove these settings.
### Go 1.6
Go 1.6 introduced transparent support for HTTP/2,
controlled by the [`http2client`, `http2server`, and `http2debug` settings](/pkg/net/http/#hdr-HTTP_2).
There is no plan to remove these settings.
### Go 1.5
Go 1.5 introduced a pure Go DNS resolver,
controlled by the [`netdns` setting](/pkg/net/#hdr-Name_Resolution).
There is no plan to remove this setting.

# README.md
This directory holds build scripts for unofficial, unsupported
distributions of Go+BoringCrypto.
## Version strings
The distribution name for a Go+BoringCrypto release has the form `<GoVersion>b<BoringCryptoVersion>`,
where `<GoVersion>` is the Go version the release is based on, and `<BoringCryptoVersion>` is
an integer that increments each time there is a new release with different BoringCrypto bits.
The `<BoringCryptoVersion>` is stored in the `VERSION` file in this directory.
For example, the first release is based on Go 1.8.3 is `go1.8.3b1`.
If the BoringCrypto bits are updated, the next would be `go1.8.3b2`.
If, after that, Go 1.9 is released and the same BoringCrypto code added to it,
that would result in `go1.9b2`. There would likely not be a `go1.9b1`,
since that would indicate Go 1.9 with the older BoringCrypto code.
## Releases
The `build.release` script prepares a binary release and publishes it in Google Cloud Storage
at `gs://go-boringcrypto/`, making it available for download at
`https://go-boringcrypto.storage.googleapis.com/<FILE>`.
The script records each published release in the `RELEASES` file in this directory.
The `build.docker` script, which must be run after `build.release`, prepares a Docker image
and publishes it on hub.docker.com in the goboring organization.
`go1.8.3b1` is published as `goboring/golang:1.8.3b1`.
## Release process
Development is done on the dev.boringcrypto branch, which tracks
master. Releases are cut from dev.boringcrypto.go1.X branches,
which are BoringCrypto backported to the Go 1.X release branches.
To issue new BoringCrypto releases based on Go 1.X:
1. If the BoringCrypto bits have been updated, increment the
number in `VERSION`, send that change out as a CL for review,
get it committed to dev.boringcrypto, and run `git sync`.
2. Change to the dev.boringcrypto.go1.X branch and cherry-pick
all BoringCrypto updates, including the update of the
`VERSION` file. If desired, merge release-branch.go1.X into
dev.boringcrypto.go1.X. Mail them out and get them committed.
3. **Back on the dev.boringcrypto branch**, run `git fetch`,
`make.bash` and then `build.release dev.boringcrypto.go1.X`.
The script will determine the base Go version and the
BoringCrypto version, build a release, and upload it.
4. Run `build.docker`, which will build and upload a Docker image
from the latest release.
5. Send out a CL with the updated `RELEASES` file and get it
committed to dev.boringcrypto.
## Building from Docker
A Dockerfile that starts with `FROM golang:1.8.3` can switch
to `FROM goboring/golang:1.8.3b2` (see [goboring/golang on Docker Hub](https://hub.docker.com/r/goboring/golang/))
and should need no other modifications.
## Building from Bazel
Starting from [bazelbuild/rules_go](https://github.com/bazelbuild/rules_go)
tag 0.7.1, simply download the BoringCrypto-enabled Go SDK using
`go_download_sdk()` before calling `go_register_toolchains()`.
For example, to use Go 1.9.3 with BoringCrypto on Linux, use the following lines
in `WORKSPACE`:
```python
load("@io_bazel_rules_go//go:def.bzl", "go_rules_dependencies", "go_download_sdk", "go_register_toolchains")
go_rules_dependencies()
go_download_sdk(
name = "go_sdk",
sdks = {
"linux_amd64": ("go1.9.3b4.linux-amd64.tar.gz", "db1997b2454a2f27669b849d2d2cafb247a55128d53da678f06cb409310d6660"),
},
urls = ["https://storage.googleapis.com/go-boringcrypto/{}"],
)
go_register_toolchains()
```
**Note**: you must *not* enable `pure` mode, since cgo must be enabled. To
ensure that binaries are linked with BoringCrypto, you can set `pure = "off"` on
all relevant `go_binary` rules.
## Caveat
BoringCrypto is used for a given build only in limited circumstances:
- The build must be GOOS=linux, GOARCH=amd64.
- The build must have cgo enabled.
- The android build tag must not be specified.
- The cmd_go_bootstrap build tag must not be specified.
The version string reported by `runtime.Version` does not indicate that BoringCrypto
was actually used for the build. For example, linux/386 and non-cgo linux/amd64 binaries
will report a version of `go1.8.3b2` but not be using BoringCrypto.
To check whether a given binary is using BoringCrypto, run `go tool nm` on it and check
that it has symbols named `*_Cfunc__goboringcrypto_*`.
The program [rsc.io/goversion](https://godoc.org/rsc.io/goversion) will report the
crypto implementation used by a given binary when invoked with the `-crypto` flag.
