2014-09-08build: move package sources from src/pkg to srcRuss Cox
Preparation was in CL 134570043. This CL contains only the effect of 'hg mv src/pkg/* src'. For more about the move, see golang.org/s/go14nopkg.
2014-08-19os: make SameFile handle paths like c:a.txt properlyAlex Brainman
Fixes #8490. LGTM=r, rsc R=golang-codereviews, rsc, bradfitz, r CC=golang-codereviews https://golang.org/cl/127740043
2014-08-12all: copy cmd/ld/textflag.h into pkg/GOOS_GOARCHRob Pike
The file is used by assembly code to define symbols like NOSPLIT. Having it hidden inside the cmd directory makes it hard to access outside the standard repository. Solution: As with a couple of other files used by cgo, copy the file into the pkg directory and add a -I argument to the assembler to access it. Thus one can write just #include "textflag.h" in .s files. The names in runtime are not updated because in the boot sequence the file has not been copied yet when runtime is built. All other .s files in the repository are updated. Changes to doc/asm.html, src/cmd/dist/build.c, and src/cmd/go/build.go are hand-made. The rest are just the renaming done by a global substitution. (Yay sam). LGTM=rsc R=rsc CC=golang-codereviews https://golang.org/cl/128050043

2014-07-03cmd/go, cmd/ld, runtime, os/user: TLS emulation for androidDavid Crawshaw
Based on cl/69170045 by Elias Naur. There are currently several schemes for acquiring a TLS slot to save the g register. None of them appear to work for android. The closest are linux and darwin. Linux uses a linker TLS relocation. This is not supported by the android linker. Darwin uses a fixed offset, and calls pthread_key_create until it gets the slot it wants. As the runtime loads late in the android process lifecycle, after an arbitrary number of other libraries, we cannot rely on any particular slot being available. So we call pthread_key_create, take the first slot we are given, and put it in runtime.tlsg, which we turn into a regular variable in cmd/ld. Makes android/arm cgo binaries work.

Add nacl.bash, the NaCl version of all.bash. It's a separate script because it builds a variant of package syscall with a large zip file embedded in it, containing all the input files needed for tests.

2014-03-12os: relax the way we kill processes on Plan 9Anthony Martin
Previously, we wrote "kill" to the process control file to kill a program. This is problematic because it doesn't let the program gracefully exit. This matters especially if the process we're killing is a Go program. On Unix, sending SIGKILL to a Go program will automatically kill all runtime threads. On Plan 9, there are no threads so when the program wants to exit it has to somehow signal all of the runtime processes. It can't do this if we mercilessly kill it by writing to it's control file. Instead, we now send it a note to invoke it's note handler and let it perform any cleanup before exiting. LGTM=rsc R=rsc, 0intro CC=golang-codereviews https://golang.org/cl/74440044

2014-02-25all: merge NaCl branch (part 1)Dave Cheney
See golang.org/s/go13nacl for design overview. This CL is the mostly mechanical changes from rsc's Go 1.2 based NaCl branch, specifically 39cb35750369 to 500771b477cf from https://code.google.com/r/rsc-go13nacl. This CL does not include working NaCl support, there are probably two or three more large merges to come. CL 15750044 is not included as it involves more invasive changes to the linker which will need to be merged separately. The exact change lists included are 15050047: syscall: support for Native Client 15360044: syscall: unzip implementation for Native Client 15370044: syscall: Native Client SRPC implementation 15400047: cmd/dist, cmd/go, go/build, test: support for Native Client 15410048: runtime: support for Native Client 15410049: syscall: file descriptor table for Native Client 15410050: syscall: in-memory file system for Native Client 15440048: all: update +build lines for Native Client port 15540045: cmd/6g, cmd/8g, cmd/gc: support for Native Client 15570045: os: support for Native Client 15680044: crypto/..., hash/crc32, reflect, sync/atomic: support for amd64p32 15690044: net: support for Native Client 15690048: runtime: support for fake time like on Go Playground 15690051: build: disable various tests on Native Client LGTM=rsc R=rsc CC=golang-codereviews https://golang.org/cl/68150047

2014-02-03os/exec: fix Command with relative pathsBrad Fitzpatrick
Command was (and is) documented like: "If name contains no path separators, Command uses LookPath to resolve the path to a complete name if possible. Otherwise it uses name directly." But that wasn't true. It always did LookPath, and then set a sticky error that the user couldn't unset. And then if cmd.Dir was changed, Start would still fail due to the earlier sticky error being set. This keeps LookPath in the same place as before (so no user visible changes in cmd.Path after Command), but only does it when the documentation says it will happen. Also, clarify the docs about a relative Dir path. No change in any existing behavior, except using Command is now possible with relative paths. Previously it only worked if you built the *Cmd by hand. Fixes #7228 LGTM=iant R=iant CC=adg, golang-codereviews https://golang.org/cl/59580044

2013-12-18crypto/x509: add non-cgo darwin system anchor certsJosh Bleecher Snyder
The set of certs fetched via exec'ing `security` is not quite identical to the certs fetched via the cgo call. The cgo fetch includes any trusted root certs that the user may have added; exec does not. The exec fetch includes an Apple-specific root cert; the cgo fetch does not. Other than that, they appear to be the same. Unfortunately, os/exec depends on crypto/x509, via net/http. Break the circular dependency by moving the exec tests to their own package. This will not work in iOS; we'll cross that bridge when we get to it. R=golang-dev, minux.ma, agl CC=golang-dev https://golang.org/cl/22020045

2013-10-29os: do not return Lstat errors from ReaddirRuss Cox
This CL restores the Go 1.1.2 semantics for os.File's Readdir method. The code in Go 1.1.2 was rewritten mainly because it looked buggy. This new version attempts to be clearer but still provide the 1.1.2 results. The important diff is not this CL's version against tip but this CL's version against Go 1.1.2. Go 1.1.2: names, err := f.Readdirnames(n) fi = make([]FileInfo, len(names)) for i, filename := range names { fip, err := Lstat(dirname + filename) if err == nil { fi[i] = fip } else { fi[i] = &fileStat{name: filename} } } return fi, err This CL: names, err := f.Readdirnames(n) fi = make([]FileInfo, len(names)) for i, filename := range names { fip, lerr := lstat(dirname + filename) if lerr != nil { fi[i] = &fileStat{name: filename} continue } fi[i] = fip } return fi, err The changes from Go 1.1.2 are stylistic, not semantic: 1. Use lstat instead of Lstat, for testing (done before this CL). 2. Make error handling in loop body look more like an error case. 3. Use separate error variable name in loop body, to be clear we are not trying to influence the final return result. Fixes #6656. Fixes #6680.
