Previously if a context was canceled while it was waiting for a connection request, that connection request would leak. To prevent this remove the pending connection request if the context is canceled and ensure no connection has been sent on the channel. This requires a change to how the connection requests are represented in the DB.

This lets the compiler inline functions that contain a linknamed symbol. Previously, the net/http tests would fail to build with -l=4 because the compiler inlined functions that call net.byteIndex (which is linknamed to strings.IndexByte). This changes only the compiler-specific export data, so we don't need to bump the export format version number. The following benchmark results show how the size of package export data is impacted by this change. These benchmarks were created by compiling the go1 benchmark and running `go tool pack x` to extract the export data from the resulting .a files. name old bytes new bytes delta bufio 3.48k ± 0% 3.58k ± 0% +2.90% bytes 5.05k ± 0% 5.16k ± 0% +2.16% compress/bzip2 2.61k ± 0% 2.68k ± 0% +2.68% compress/flate 5.07k ± 0% 5.14k ± 0% +1.40% compress/gzip 8.26k ± 0% 8.40k ± 0% +1.70% container/list 1.69k ± 0% 1.76k ± 0% +4.07% context 3.93k ± 0% 4.01k ± 0% +1.86% crypto 1.03k ± 0% 1.03k ± 0% +0.39% crypto/aes 475 ± 0% 475 ± 0% +0.00% crypto/cipher 1.18k ± 0% 1.18k ± 0% +0.00% crypto/des 502 ± 0% 502 ± 0% +0.00% crypto/dsa 5.71k ± 0% 5.77k ± 0% +1.16% crypto/ecdsa 6.67k ± 0% 6.75k ± 0% +1.08% crypto/elliptic 6.28k ± 0% 6.35k ± 0% +1.07% crypto/hmac 464 ± 0% 464 ± 0% +0.00% crypto/internal/cipherhw 313 ± 0% 313 ± 0% +0.00% crypto/md5 691 ± 0% 695 ± 0% +0.58% crypto/rand 5.37k ± 0% 5.43k ± 0% +1.23% crypto/rc4 512 ± 0% 512 ± 0% +0.00% crypto/rsa 7.05k ± 0% 7.12k ± 0% +1.05% crypto/sha1 756 ± 0% 760 ± 0% +0.53% crypto/sha256 523 ± 0% 523 ± 0% +0.00% crypto/sha512 662 ± 0% 662 ± 0% +0.00% crypto/subtle 835 ± 0% 873 ± 0% +4.55% crypto/tls 28.1k ± 0% 28.5k ± 0% +1.30% crypto/x509 17.7k ± 0% 17.9k ± 0% +1.04% crypto/x509/pkix 9.75k ± 0% 9.90k ± 0% +1.50% encoding 473 ± 0% 473 ± 0% +0.00% encoding/asn1 1.41k ± 0% 1.42k ± 0% +1.00% encoding/base64 1.67k ± 0% 1.69k ± 0% +0.90% encoding/binary 2.65k ± 0% 2.76k ± 0% +4.07% encoding/gob 13.3k ± 0% 13.5k ± 0% +1.65% encoding/hex 854 ± 0% 857 ± 0% +0.35% encoding/json 11.9k ± 0% 12.1k ± 0% +1.71% encoding/pem 484 ± 0% 484 ± 0% +0.00% errors 360 ± 0% 361 ± 0% +0.28% flag 7.32k ± 0% 7.42k ± 0% +1.48% fmt 1.42k ± 0% 1.42k ± 0% +0.00% go/ast 15.7k ± 0% 15.8k ± 0% +1.07% go/parser 7.48k ± 0% 7.59k ± 0% +1.55% go/scanner 3.88k ± 0% 3.94k ± 0% +1.39% go/token 3.51k ± 0% 3.53k ± 0% +0.60% hash 507 ± 0% 507 ± 0% +0.00% hash/crc32 685 ± 0% 685 ± 0% +0.00% internal/nettrace 474 ± 0% 474 ± 0% +0.00% internal/pprof/profile 8.29k ± 0% 8.36k ± 0% +0.89% internal/race 511 ± 0% 511 ± 0% +0.00% internal/singleflight 966 ± 0% 969 ± 0% +0.31% internal/syscall/unix 427 ± 0% 427 ± 0% +0.00% io 3.48k ± 0% 3.52k ± 0% +1.15% io/ioutil 5.30k ± 0% 5.38k ± 0% +1.53% log 4.46k ± 0% 4.53k ± 0% +1.59% math 3.72k ± 0% 3.75k ± 0% +0.75% math/big 8.91k ± 0% 9.01k ± 0% +1.15% math/rand 1.29k ± 0% 1.30k ± 0% +0.46% mime 2.59k ± 0% 2.63k ± 0% +1.55% mime/multipart 3.61k ± 0% 3.68k ± 0% +1.80% mime/quotedprintable 2.20k ± 0% 2.25k ± 0% +2.50% net 21.1k ± 0% 21.3k ± 0% +1.10% net/http 56.6k ± 0% 57.3k ± 0% +1.28% net/http/httptest 33.6k ± 0% 34.1k ± 0% +1.38% net/http/httptrace 14.4k ± 0% 14.5k ± 0% +1.29% net/http/internal 2.70k ± 0% 2.77k ± 0% +2.59% net/textproto 4.51k ± 0% 4.60k ± 0% +1.82% net/url 1.71k ± 0% 1.73k ± 0% +1.41% os 11.3k ± 0% 11.4k ± 0% +1.36% path 587 ± 0% 589 ± 0% +0.34% path/filepath 4.46k ± 0% 4.55k ± 0% +1.88% reflect 6.39k ± 0% 6.43k ± 0% +0.72% regexp 5.82k ± 0% 5.88k ± 0% +1.12% regexp/syntax 3.22k ± 0% 3.24k ± 0% +0.62% runtime 12.9k ± 0% 13.2k ± 0% +1.94% runtime/cgo 229 ± 0% 229 ± 0% +0.00% runtime/debug 3.66k ± 0% 3.72k ± 0% +1.86% runtime/internal/atomic 905 ± 0% 905 ± 0% +0.00% runtime/internal/sys 2.00k ± 0% 2.05k ± 0% +2.55% runtime/pprof 4.16k ± 0% 4.23k ± 0% +1.66% runtime/pprof/internal/protopprof 11.5k ± 0% 11.7k ± 0% +1.27% runtime/trace 354 ± 0% 354 ± 0% +0.00% sort 1.63k ± 0% 1.68k ± 0% +2.94% strconv 1.84k ± 0% 1.85k ± 0% +0.54% strings 3.87k ± 0% 3.97k ± 0% +2.48% sync 1.51k ± 0% 1.52k ± 0% +0.33% sync/atomic 1.58k ± 0% 1.60k ± 0% +1.27% syscall 53.2k ± 0% 53.3k ± 0% +0.20% testing 8.14k ± 0% 8.26k ± 0% +1.49% testing/internal/testdeps 597 ± 0% 598 ± 0% +0.17% text/tabwriter 3.09k ± 0% 3.14k ± 0% +1.85% text/template 15.4k ± 0% 15.7k ± 0% +1.89% text/template/parse 8.90k ± 0% 9.12k ± 0% +2.46% time 5.75k ± 0% 5.86k ± 0% +1.86% unicode 4.62k ± 0% 4.62k ± 0% +0.07% unicode/utf16 693 ± 0% 706 ± 0% +1.88% unicode/utf8 1.05k ± 0% 1.07k ± 0% +1.14% vendor/golang_org/x/crypto/chacha20poly1305 1.25k ± 0% 1.26k ± 0% +0.64% vendor/golang_org/x/crypto/curve25519 392 ± 0% 392 ± 0% +0.00% vendor/golang_org/x/crypto/poly1305 426 ± 0% 426 ± 0% +0.00% vendor/golang_org/x/net/http2/hpack 4.19k ± 0% 4.26k ± 0% +1.69% vendor/golang_org/x/net/idna 355 ± 0% 355 ± 0% +0.00% vendor/golang_org/x/net/lex/httplex 609 ± 0% 615 ± 0% +0.99% vendor/golang_org/x/text/transform 1.31k ± 0% 1.31k ± 0% +0.08% vendor/golang_org/x/text/unicode/norm 5.78k ± 0% 5.90k ± 0% +2.06% vendor/golang_org/x/text/width 1.24k ± 0% 1.24k ± 0% +0.16% [Geo mean] 2.49k 2.52k +1.10% Fixes #18167.

Some rules insert MOVDreg ops to ensure that type changes are kept. If there is no type change (or the input is constant) then the MOVDreg can be omitted, allowing further optimization.

Previously it was intended that Rows.Scan would return an error and Rows.Err would return nil. This was problematic because drivers could not differentiate between a normal Rows.Close or a context cancel close. The alternative is to require drivers to return a Scan to return an error if the driver is closed while there are still rows to be read. This is currently not how several drivers currently work and may be difficult to detect when there are additional rows. At the same time guard the the Rows.lasterr and prevent a close while a Rows operation is active. For the drivers that do not have Context methods, do not check for context cancelation after the operation, but before for any operation that may modify the database state.

The fwdSig array is accessed by the signal handler, which may run in parallel with other threads manipulating it via the os/signal package. Use atomic accesses to ensure that there are no problems. Move the _SigHandling flag out of the sigtable array. This makes sigtable immutable and safe to read from the signal handler.

CL 20845 changed Stdin.Stat() so it returns ModeNamedPipe. But introduced TestStatStdin does not test what Stdin.Stat() returns when Stdin is console. This CL adjusts both TestStatStdin and Stdin.Stat implementations to handle console. Return ModeCharDevice from Stdin.Stat() when Stdin is console on windows, just like it does on unix. Fixes #14853.

Currently both _MaxMem and _MaxArena32 represent the maximum arena size on 32-bit hosts (except on MIPS32 where _MaxMem is confusingly smaller than _MaxArena32). Clean up sysAlloc so that it always uses _MaxMem, which is the maximum arena size on both 32- and 64-bit architectures and is the arena size we allocate auxiliary structures for. This lets us simplify and unify some code paths and eliminate _MaxArena32. Fixes #18651. mheap.sysAlloc currently assumes that if the arena is small, we must be on a 32-bit machine and can therefore grow the arena to _MaxArena32. This breaks down on darwin/arm64, where _MaxMem is only 2 GB. As a result, on darwin/arm64, we only reserve spans and bitmap space for a 2 GB heap, and if the application tries to allocate beyond that, sysAlloc takes the 32-bit path, tries to grow the arena beyond 2 GB, and panics when it tries to grow the spans array allocation past its reserved size. This has probably been a problem for several releases now, but was only noticed recently because mapSpans didn't check the bounds on the span reservation until recently. Most likely it corrupted the bitmap before. By using _MaxMem consistently, we avoid thinking that we can grow the arena larger than we have auxiliary structures for.

mallocinit has evolved organically. Make a pass to clean it up in various ways: 1. Merge the computation of spansSize and bitmapSize. These were computed on every loop iteration of two different loops, but always have the same value, which can be derived directly from _MaxMem. This also avoids over-reserving these on MIPS, were _MaxArena32 is larger than _MaxMem. 2. Remove the ulimit -v logic. It's been disabled for many releases and the dead code paths to support it are even more wrong now than they were when it was first disabled, since now we *must* reserve spans and bitmaps for the full address space. 3. Make it clear that we're using a simple linear allocation to lay out the spans, bitmap, and arena spaces. Previously there were a lot of redundant pointer computations. Now we just bump p1 up as we reserve the spaces. In preparation for #18651. Updates #5049 (respect ulimit).

The compiler did not emit write barrier for assigning global with struct literal, like global = T{} where T contains pointer. The relevant code path is: walkexpr OAS var_ OSTRUCTLIT oaslit anylit OSTRUCTLIT walkexpr OAS var_ nil return without adding write barrier return true break (without adding write barrier) This CL makes oaslit not apply to globals. See also CL https://go-review.googlesource.com/c/36355/ for an alternative fix. The downside of this is that it generates static data for zeroing struct now. Also this only covers global. If there is any lurking bug with implicit zeroing other than globals, this doesn't fix. Fixes #18956.

We added CentOS 7's /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem to the list in response to #17549 - not being able to find any certs otherwise. Now we have #18813, where CentOS 6 apparently has both that file and /etc/pki/tls/certs/ca-bundle.crt, and the latter is complete while the former is not. Moving the new CentOS 7 file to the bottom of the list should fix both problems: the CentOS 7 system that didn't have any of the other files in the list will still find the new one, and existing systems will still keep using what they were using instead of preferring the new path that may or may not be complete on some systems. Fixes #18813. Change-Id: I5275ab67424b95e7210e14938d3e986c8caee0ba Reviewed-on: https://go-review.googlesource.com/36429 Run-TryBot: Russ Cox <rsc@golang.org> Reviewed-by:
