2009-04-20Use the mutex in exvar.Set since map access is not atomic.David Symonds1-0/+3
Imagine your var has a value of zero. If you have a goroutine calling Set(5), and another calling Increment(+1), then you only want one of these outcomes: - Set completes first, and then Increment occurs => 6 - Increment completes first, and then Set occurs => 5 However, you could get a sequence: - read (for Increment) 0 - set (for Set) 5 - write (for Increment) 1 This results in a value of 1, which is undesirable. Kudos to dnadasi for catching this. R=r APPROVED=r DELTA=3 (3 added, 0 deleted, 0 changed) OCL=27625 CL=27625

2009-04-19Initial cut at an "exported variables" (exvar) package.David Symonds4-0/+127
This handles integer-valued vars in a singleton struct, and exports functions for incrementing, setting and getting those vars, as well as rendering all the vars in a standard format.

2009-04-17add -P pkgdir option to 6l to have it look first in pkgdir for a package.Rob Pike3-2/+11
this allows gotest to find the locally built package when doing make gotest without this option, one would have to say make install gotest which kinda defeats the purpose based on discussions with rsc. R=ken,rsc DELTA=12 (10 added, 1 deleted, 1 changed) OCL=27606 CL=27606
2009-04-17Step 2 of the Big Error Shift.Rob Pike1-65/+61
Change the representation of errors in "os" to be cleaner. (But they are not really representative of the power of the new scheme.) Step 3 will be to remove all references to os.NewError. Step 4 will be to delete the second half of lib/os/error.go. R=rsc OCL=27587 CL=27587

2009-04-16Convert go tree to hierarchical pkg directory:Russ Cox59-291/+363
import ( "vector" -> "container/vector" "ast" -> "go/ast" "sha1" -> "hash/sha1" etc. ) and update Makefiles. Because I did the conversion semi-automatically, I sorted all the import blocks as a post-processing. Some files have therefore changed that didn't strictly need to. Rename local packages to lower case. The upper/lower distinction doesn't work on OS X and complicates the "single-package directories with the same package name as directory name" heuristic used by gobuild and godoc to create the correlation between source and binary locations. Now that we have a plan to avoid globally unique names, the upper/lower is unnecessary. The renamings will cause trouble for a few users, but so will the change in import paths. This way, the two maintenance fixes are rolled into one inconvenience. R=r OCL=27573 CL=27575
2009-04-16build packages in obj/ subdirectory that mimics $GOROOT/pkg.Russ Cox4-18/+115
for example, if building in src/lib/container, objects go in obj/container/, so that 6g -Iobj will find "container/vector". install packages in hierarchy in $GOROOT. this change only updates gobuild. another change will have to update all the sources to refer to "container/vector" etc and regenerate all the Makefiles. there are some pretty lame functions here (e.g., Mkdir, Remove, the Getenv("PWD")) but i will implement better ones in another CL.
