* build: remove Make.pkg, Make.toolRuss Cox2012-01-301-244/+0
| | | | | | | | | | | | | | | Consequently, remove many package Makefiles, and shorten the few that remain. gomake becomes 'go tool make'. Turn off test phases of run.bash that do not work, flagged with $BROKEN. Future CLs will restore these, but this seemed like a big enough CL already. R=golang-dev, r CC=golang-dev http://codereview.appspot.com/5601057
* go: move compilers into the go-tool directoryRob Pike2012-01-301-9/+4
| | | | | | | | | | | | Also delete gotest, since it's messy to fix and slated for deletion anyway. A couple of things outside src can't be tested any more. "go test" will be fixed and these tests will be re-enabled. They're noisy for now. Fixes issue 284. R=rsc CC=golang-dev http://codereview.appspot.com/5598049

* runtime: separate out auto-generated files, take 2Russ Cox2011-12-191-1/+1
| | | | | | | | | | This is like the ill-fated CL 5493063 except that I have written a shell script (autogen.sh) instead of thinking I could possibly write a correct Makefile. R=golang-dev, r CC=golang-dev http://codereview.appspot.com/5496075
* runtime: hg revert -r 6ec0a5c12d75Russ Cox2011-12-161-1/+1
| | | | | | | | | | | | | That was the last build that was close to working. I will try that change again next week. Make is being very subtle today. At the reverted-to CL, the ARM traceback appears to be broken. I'll look into that next week too. R=golang-dev, r CC=golang-dev http://codereview.appspot.com/5492063

* build: pass $GCFLAGS to compilerRuss Cox2011-10-181-2/+2
| | | | | | | | | | | | | | | | | | For example, if you are debugging an optimization problem you can now run GCFLAGS=-N gotest This is a convention for make, not for the general build, so it may go away or be done differently in the eventual 'go' command. The plan is that people will be able to test their code for rune safety by doing GCFLAGS=-r. R=golang-dev, bradfitz, lvd CC=golang-dev http://codereview.appspot.com/5294042
* gc: add -p flag to catch import cycles earlierRuss Cox2011-09-071-2/+2
| | | | | | | | | | | | | | | | | | | | | The linker would catch them if gc succeeded, but too often the cycle manifests as making the current package and the imported copy of itself appear as different packages, which result in type signature mismatches that confuse users. As a crutch, add the -p flag to say 'if you see an import of this package, give up early'. Results in messages like (during gotest in sort): export_test.go:7: import "sort" while compiling that package (import cycle) export_test.go:7: import "container/heap": package depends on "sort" (import cycle) Fixes issue 2042.

* build: remove rm dregRuss Cox2011-07-261-1/+1

* goinstall: support GOPATH; building and installing outside the Go treeAndrew Gerrand2011-04-271-10/+14
| | | | | | | | | | | | | | | | | | | | | | For example, with GOPATH set like so GOPATH=/home/adg/gocode And after creating some subdirectories mkdir /home/adg/gocode/{bin,pkg,src} I can use goinstall to install the github.com/nf/goto web server, which depends on the github.com/nf/stat package, with goinstall github.com/nf/goto This downloads and installs all dependencies (that aren't already installed) like so /home/adg/gocode/bin/goto /home/adg/gocode/pkg/darwin_amd64/github.com/nf/stat.a /home/adg/gocode/src/github.com/nf/goto/... /home/adg/gocode/src/github.com/nf/stat/...

* testing: add -test.timeout option.Ian Lance Taylor2011-03-311-1/+1
| | | | | | | | | | | Since Go code can deadlock, this lets a testsuite driver set a time limit for the test to run. This is simple but imperfect, in that it only catches deadlocks in Go code, not in the runtime scheduler. R=r, rsc, iant2 CC=golang-dev http://codereview.appspot.com/4326048

Use -test.short to make one package (crypto ecdsa) run much faster. More changes to come. Once this is in, I will update the long-running tests to use the new flag.

* runtime: fix signal stack bugRuss Cox2011-02-241-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | In CL 4188061 I changed malg to allocate the requested number of bytes n, not n+StackGuard, so that the allocations would use rounder numbers. The allocation of the signal stack asks for 32k and then used g->stackguard as the base, but g->stackguard is StackGuard bytes above the base. Previously, asking for 32k meant getting 32k+StackGuard bytes, so using g->stackguard as the base was safe. Now, the actual base must be computed, so that the signal handler does not run StackGuard bytes past the top of the stack. Was causing flakiness mainly in programs that use the network, because they sometimes write to closed network connections, causing SIGPIPEs. Was also causing problems in the doc/progs test. Also fix Makefile so that changes to stack.h trigger rebuild. R=bradfitzgo, r, r2 CC=golang-dev http://codereview.appspot.com/4230044

* cgo: don't run cgo when not compilingGustavo Niemeyer2011-02-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The logic introduced to avoid running cgo when introducing _cgo_flags is faulty. My goal was to handle it with the following statement: -include _cgo_flags The dash tells make to ignore errors if it can't include the file. What I missed, though, was the fact that it *will* attempt to build the file if it knows how. This change will introduce the originally intended semantics of not attempting to build the file before necessary.

* cgo: fix _cgo_run timestamp file orderGustavo Niemeyer2011-02-021-1/+1
| | | | | | | | | | | | | | The timestamp file is being created before cgo runs, which means errors will not prevent it from being created and thus will cause the build to break by rendering the rule up-to-date when it isn't.

* misc/cgo/life: fix, add to buildRuss Cox2010-12-171-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | #pragma dynexport is no longer needed for this use of cgo, since the gcc and gc code are now linked together into the same binary. It may still be necessary later. On the Mac, you cannot use the GOT to resolve symbols that exist in the current binary, so 6l and 8l translate the GOT-loading mov instructions into lea instructions. On ELF systems, we could use the GOT for those symbols, but for consistency 6l and 8l apply the same translation. The translation is sketchy in the extreme (depending on the relocation being in a mov instruction) but it verifies that the instruction is a mov before rewriting it to lea. Also makes typedefs global across files. Fixes issue 1335. Fixes issue 1345. R=iant, r CC=golang-dev http://codereview.appspot.com/3650042

* Make.pkg: remove .so before installing new oneRuss Cox2010-10-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | On Linux, overwriting an mmap'ed file causes all the MAP_PRIVATE pages to get refreshed with the new content, even ones that have been modified by the process that did the mmap. One specific instance of this is that after the dynamic linker has relocated a page from a .so, overwriting the .so will un-relocate it, making the next use of one of the no-longer-relocated addresses incorrect and probably crash the program. Linux must go out of its way to break programs in this way: the pages have already been copied on write, so they're not shared with the file system cache, and it trashes them anyway. The manual says the behavior when the file gets overwritten is "undefined". Removing before copy avoids the undefined behavior. R=iant CC=golang-dev, msolo http://codereview.appspot.com/2333045

* cgo: use slash-free relative paths for .so referencesRuss Cox2010-06-301-2/+3
| | | | | | | | | | | | | | | The Makefile and cgo now rewrite / to _ when creating the path. The .so for gosqlite.googlecode.com/hg/sqlite is named cgo_gosqlite.googlecode.com_hg_sqlite.so, and then 6l and 8l both include a default rpath of $GOROOT/pkg/$GOOS_$GOARCH.

* Add _cgo_export.[ch] targets so that make knows how they areIan Lance Taylor2010-05-031-1/+1
| | | | | | | | | | | | built. Note that they are only built if a //export comment appears, so other targets should only use them if there is such a comment. Fixes issue 723. R=rsc CC=golang-dev http://codereview.appspot.com/1073041
* Add //export to cgo.Ian Lance Taylor2010-04-091-5/+9
| | | | | | | | | | | | | | | | | The new //export comment marks a Go function as callable from C. The syntax is "//export NAME" where NAME is the name of the function as seen from C. If such a comment is seen, cgo will generate two new files: _cgo_export.h and _cgo_export.c. The _cgo_export.h file provides declarations which C code may use to call Go functions. The _cgo_export.c file contains wrappers, and is to be compiled with gcc. The changes to Make.pkg support using this from a Go Makefile, though it could probably be more convenient.
