* Rewrite the flushing code to not use a persistent goroutine, which also simplifies testing. * Define the meaning of a negative flush interval. Its meaning doesn't change, but now it's locked in, and then we can use it to optimize the performance of the non-buffered case to avoid use of an AfterFunc. * Support (internal-only) special casing of FlushInterval values per request/response. * For now, treat Server-Sent Event responses as unbuffered. (or rather, immediately flushed from the buffer per-write) Fixes #27816 Change-Id: Ie0f975c997daa3db539504137c741a96d7022665 Reviewed-on: https://go-review.googlesource.com/c/137335 Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

According to https://tools.ietf.org/html/rfc6962#section-3.3, the SCT must be at least one byte long. The parsing code correctly checks for this condition, but rarely the test does generate an empty SCT.

The spec used the term "conversion" somewhat indiscriminately for explicit conversions that appear literally in the source, and implicit conversions that are implied by the context of an expression. Be clearer about it by defining the terms. Also, state that integer to string conversions of the form string(x) are never implicit. This clarifies situations where implicit conversions might require an integer to change to a string (but don't and never have done so). See line 3948. Fixes #26313.

Reason for revert: It broke all the darwin builders; it's also not obvious how the weird darwin versions (900, 1000) relate to the > 3.9 requisite, so I'm not sure how to decide about skipping in a robust way.

This is similar to CL 136816 for x/sys/unix, changing the FreeBSD ABI to use 64-bit inodes in Stat_t, Statfs_t, and Dirent types. The changes are forward compatible, that is FreeBSD 10.x, 11.x continue to use their current sysnum numbers. The affected types are converted to the new layout (with some overhead). Thus the same statically linked binary should work using the native sysnums (without any conversion) on FreeBSD 12. Breaking API changes in package syscall are: Mknod takes a uint64 (C dev_t) instead of int. Stat_t: Dev, Ino, Nlink, Rdev, Gen became uint64. Atimespec, Mtimespec, Ctimespec, Birthtimespec renamed to Atim, Mtim, Ctim, Birthtim respectively. Statfs_t: Mntonname and Mntfromname changed from [88]int8 to [1024]int8 arrays. Dirent: Fileno became uint64, Namlen uint16 and an additional field Off int64 (currently unused) was added. The following commands were run to generate ztypes_* and zsyscall_* on FreeBSD-12.0-ALPHA6 systems (GOARCH=386 were run on the same amd64 host): GOOS=freebsd GOARCH=amd64 ./mksyscall.pl -tags freebsd,amd64 syscall_bsd.go syscall_freebsd.go syscall_freebsd_amd64.go |gofmt >zsyscall_freebsd_amd64.go GOOS=freebsd GOARCH=amd64 go tool cgo -godefs types_freebsd.go | GOOS=freebsd GOARCH=amd64 go run mkpost.go >ztypes_freebsd_amd64.go GOOS=freebsd GOARCH=386 ./mksyscall.pl -l32 -tags freebsd,386 syscall_bsd.go syscall_freebsd.go syscall_freebsd_386.go |gofmt >zsyscall_freebsd_386.go GOOS=freebsd GOARCH=386 go tool cgo -godefs types_freebsd.go | GOOS=freebsd GOARCH=386 go run mkpost.go >ztypes_freebsd_386.go GOOS=freebsd GOARCH=arm ./mksyscall.pl -l32 -arm -tags freebsd,arm syscall_bsd.go syscall_freebsd.go syscall_freebsd_arm.go |gofmt >zsyscall_freebsd_arm.go GOOS=freebsd GOARCH=arm go tool cgo -godefs -- -fsigned-char types_freebsd.go | GOOS=freebsd GOARCH=arm go run mkpost.go >ztypes_freebsd_arm.go The Kevent struct was changed to use the FREEBSD_COMPAT11 version always (requiring the COMPAT_FREEBSD11 kernel option FreeBSD-12, this is the default).

Remove assumption that methods associated to concrete (non-interface) types have a fully set up signature. Such methods are found through LookupFieldOrMethod or lookupMethod, or indexed method access from a Named type. Make sure that the method's signature is type-checked before use in those cases. (MethodSets also hold methods but the type checker is not using them but for internal verification. API clients will be using it after all methods have been type-checked.) Some functions such as MissingMethod may now have to type-check a method and for that they need a *Checker. Add helper functions as necessary to provide the additional (receiver) parameter but permit it to be nil if the respective functions are invoked through the API (at which point we know that all methods have a proper signature and thus we don't need the delayed type-check). Since all package-level objects eventually are type-checked through the top-level loop in Checker.packageObjects we are guaranteed that all methods will be type-checked as well. Updates #23203.

The origin tagKey is just dirname if no tags input which will cause pkgCache missmatch if other imported pkg explicit on GOARCH or GOOS This CL will add GOOS and GOARCH to tagKey Fixes #8425 Fixes #21181 Change-Id: Ifc189cf6746d753ad7c7e5bb60621297fc0a4e35 Reviewed-on: https://go-review.googlesource.com/c/138315Reviewed-by:

The alloc_m documentation refers to concepts that don't exist (and maybe never did?). alloc_m is also not the API entry point to span allocation. Hence, rewrite the documentation for alloc and alloc_m. While we're here, document why alloc_m must run on the system stack and replace alloc_m's hand-implemented system stack check with a go:systemstack annotation.

.rel symbol type is sym.SELFROSECT, and that makes .rel written into .rdata section. But .rel stores code - jump table used for external C functions. So we have to mark whole .rdata section as executable (IMAGE_SCN_MEM_EXECUTE), because of .rel presence in it. Move .rel into .text section, and make .rdata section non executable. I also had to move code that adjusted the size of .rel symbol before calling textaddress, otherwise textaddress would not calculate size of .text section correctly.

On wasm, pcln tables are indexed by "resumption point ID" instead of by pc offset. When finding a deferreturn call, we must find the associated resumption point ID for the deferreturn call. Update #27518 Fixes wasm bug introduced in CL 134637. Change-Id: I3d178a3f5203a06c0180a1aa2309bfb7f3014f0f Reviewed-on: https://go-review.googlesource.com/c/139898Reviewed-by:

This change disables the export-subst and export-ignore attributes when creating zip files for modules. This is done to prevent the ziphash for a given repo/revision from differing based on variables such as git version or size of repo. The full rational for this change is detailed here: https://github.com/golang/go/issues/27153#issuecomment-420763082 Fixes #27153 Change-Id: Ib33f525d91d2581fa0b5d26e70d29620c7e685e9 Reviewed-on: https://go-review.googlesource.com/c/135175 Run-TryBot: Bryan C.

Currently "ADD $0x123456, Rs, Rd" will load pre-stored 0x123456 from the constant pool and use it for the addition. Total 12 bytes are cost. And so does SUB. This CL breaks it to "ADD 0x123000, Rs, Rd" + "ADD 0x000456, Rd, Rd". Both "0x123000" and "0x000456" can be directly encoded into the instruction binary code. So 4 bytes are saved. 1. The total size of pkg/android_arm64 decreases about 0.3KB. 2. The go1 benchmark show little regression (excluding noise). name old time/op new time/op delta BinaryTree17-4 15.9s ± 0% 15.9s ± 1% +0.10% (p=0.044 n=29+29) Fannkuch11-4 8.72s ± 0% 8.75s ± 0% +0.34% (p=0.000 n=30+24) FmtFprintfEmpty-4 173ns ± 0% 173ns ± 0% ~ (all equal) FmtFprintfString-4 368ns ± 0% 368ns ± 0% ~ (p=0.593 n=30+30) FmtFprintfInt-4 417ns ± 0% 417ns ± 0% ~ (all equal) FmtFprintfIntInt-4 673ns ± 0% 661ns ± 1% -1.70% (p=0.000 n=30+30) FmtFprintfPrefixedInt-4 805ns ± 0% 805ns ± 0% +0.10% (p=0.011 n=30+30) FmtFprintfFloat-4 1.09µs ± 0% 1.09µs ± 0% ~ (p=0.125 n=30+29) FmtManyArgs-4 2.68µs ± 0% 2.68µs ± 0% +0.07% (p=0.004 n=30+30) GobDecode-4 32.9ms ± 0% 33.2ms ± 1% +1.07% (p=0.000 n=29+29) GobEncode-4 29.5ms ± 0% 29.6ms ± 0% +0.26% (p=0.000 n=28+28) Gzip-4 1.38s ± 1% 1.35s ± 3% -1.94% (p=0.000 n=28+30) Gunzip-4 139ms ± 0% 139ms ± 0% +0.10% (p=0.000 n=28+29) HTTPClientServer-4 745µs ± 5% 742µs ± 3% ~ (p=0.405 n=28+29) JSONEncode-4 49.5ms ± 1% 49.9ms ± 0% +0.89% (p=0.000 n=30+30) JSONDecode-4 264ms ± 1% 264ms ± 0% +0.25% (p=0.001 n=30+30) Mandelbrot200-4 16.6ms ± 0% 16.6ms ± 0% ~ (p=0.507 n=29+29) GoParse-4 15.9ms ± 0% 16.0ms ± 1% +0.91% (p=0.002 n=23+30) RegexpMatchEasy0_32-4 379ns ± 0% 379ns ± 0% ~ (all equal) RegexpMatchEasy0_1K-4 1.31µs ± 0% 1.31µs ± 0% +0.09% (p=0.008 n=27+30) RegexpMatchEasy1_32-4 357ns ± 0% 358ns ± 0% +0.28% (p=0.000 n=28+29) RegexpMatchEasy1_1K-4 2.04µs ± 0% 2.04µs ± 0% ~ (p=0.850 n=30+30) RegexpMatchMedium_32-4 587ns ± 0% 589ns ± 0% +0.33% (p=0.000 n=30+30) RegexpMatchMedium_1K-4 162µs ± 0% 163µs ± 0% ~ (p=0.351 n=30+29) RegexpMatchHard_32-4 9.54µs ± 0% 9.60µs ± 0% +0.59% (p=0.000 n=28+30) RegexpMatchHard_1K-4 287µs ± 0% 287µs ± 0% +0.11% (p=0.000 n=26+29) Revcomp-4 2.50s ± 0% 2.50s ± 0% -0.13% (p=0.012 n=28+27) Template-4 312ms ± 1% 312ms ± 1% +0.20% (p=0.015 n=27+30) TimeParse-4 1.68µs ± 0% 1.68µs ± 0% -0.35% (p=0.000 n=30+30) TimeFormat-4 1.66µs ± 0% 1.64µs ± 0% -1.20% (p=0.000 n=25+29) [Geo mean] 246µs 246µs -0.00% name old speed new speed delta GobDecode-4 23.3MB/s ± 0% 23.1MB/s ± 1% -1.05% (p=0.000 n=29+29) GobEncode-4 26.0MB/s ± 0% 25.9MB/s ± 0% -0.25% (p=0.000 n=29+28) Gzip-4 14.1MB/s ± 1% 14.4MB/s ± 3% +1.94% (p=0.000 n=27+30) Gunzip-4 139MB/s ± 0% 139MB/s ± 0% -0.10% (p=0.000 n=28+29) JSONEncode-4 39.2MB/s ± 1% 38.9MB/s ± 0% -0.88% (p=0.000 n=30+30) JSONDecode-4 7.37MB/s ± 0% 7.35MB/s ± 0% -0.26% (p=0.001 n=30+30) GoParse-4 3.65MB/s ± 0% 3.62MB/s ± 1% -0.86% (p=0.001 n=23+30) RegexpMatchEasy0_32-4 84.3MB/s ± 0% 84.3MB/s ± 0% ~ (p=0.126 n=27+26) RegexpMatchEasy0_1K-4 784MB/s ± 0% 783MB/s ± 0% -0.10% (p=0.003 n=27+30) RegexpMatchEasy1_32-4 89.5MB/s ± 0% 89.3MB/s ± 0% -0.20% (p=0.000 n=27+29) RegexpMatchEasy1_1K-4 502MB/s ± 0% 502MB/s ± 0% ~ (p=0.858 n=30+28) RegexpMatchMedium_32-4 1.70MB/s ± 0% 1.70MB/s ± 0% -0.25% (p=0.000 n=30+30) RegexpMatchMedium_1K-4 6.30MB/s ± 0% 6.30MB/s ± 0% ~ (all equal) RegexpMatchHard_32-4 3.35MB/s ± 0% 3.33MB/s ± 0% -0.47% (p=0.000 n=30+30) RegexpMatchHard_1K-4 3.57MB/s ± 0% 3.56MB/s ± 0% -0.20% (p=0.000 n=27+30) Revcomp-4 102MB/s ± 0% 102MB/s ± 0% +0.14% (p=0.008 n=28+28) Template-4 6.23MB/s ± 0% 6.21MB/s ± 1% -0.21% (p=0.009 n=21+30) [Geo mean] 24.1MB/s 24.0MB/s -0.16% Change-Id: Ifcef3edb667540e2d86e586c23afcfbc2cf1340b Reviewed-on: https://go-review.googlesource.com/c/134536 Run-TryBot: Ben Shi <powerman1st@163.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:
