* cmd/cgo: given typedef struct S T, make C.T and C.struct_S interchangeableRuss Cox2014-05-281-5/+17
| | | | | | | | | | | | | | | | | | | | | | For incomplete struct S, C.T and C.struct_S were interchangeable in Go 1.2 and earlier, because all incomplete types were interchangeable (even C.struct_S1 and C.struct_S2). CL 76450043, which fixed issue 7409, made different incomplete types different from Go's point of view, so that they were no longer completely interchangeable. However, imprecision about C.T and C.struct_S - really the same underlying C type - is the one behavior enabled by the bug that is most likely to be depended on by existing cgo code. Explicitly allow it, to keep that code working. Fixes issue 7786. LGTM=iant, r R=golang-codereviews, iant, r CC=golang-codereviews https://codereview.appspot.com/98580046

* spec: explicitly disallow blank methods in interface typesRobert Griesemer2014-05-221-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The spec was unclear about whether blank methods should be permitted in interface types. gccgo permits at most one, gc crashes if there are more than one, go/types permits at most one. Discussion: Since method sets of non-interface types never contain methods with blank names (blank methods are never declared), it is impossible to satisfy an interface with a blank method. It is possible to declare variables of assignable interface types (but not necessarily identical types) containing blank methods, and assign those variables to each other, but the values of those variables can only be nil. There appear to be two "reasonable" alternatives: 1) Permit at most one blank method (since method names must be unique), and consider it part of the interface. This is what appears to happen now, with corner-case bugs. Such interfaces can never be implemented. 2) Permit arbitrary many blank methods but ignore them. This appears to be closer to the handling of blank identifiers in declarations. However, an interface type literal is not a declaration (it's a type literal). Also, for struct types, blank identifiers are not ignored; so the analogy with declarations is flawed. Both these alternatives don't seem to add any benefit and are likely (if only slightly) more complicated to explain and implement than disallowing blank methods in interfaces altogether.

* spec: specify order of init() callsgo1.3beta2Robert Griesemer2014-05-201-1/+2
| | | | | | | | | | | | | | | | | | | The spec did not specify the order in which init() functions are called. Specify that they are called in source order since we have now also specified the initialization order of independent variables. While technically a language change, no existing code could have relied on this, so this should not break anything. Per suggestion from rsc.

* spec: clarify section on package initializationRobert Griesemer2014-05-201-54/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - split description of package initialization and program execution - better grouping of concerns in section on package initialization - more explicit definition of what constitues a dependency - removed language about constant dependencies - they are computed at compile-time and not initialized at run-time - clarified that independent variables are initialized in declaration order (rather than reference order) Note that the last clarification is what distinguishes gc and gccgo at the moment: gc uses reference order (i.e., order in which variables are referenced in initialization expressions), while gccgo uses declaration order for independent variables. Not a language change. But adopting this CL will clarify what constitutes a dependency. Fixes issue 6703.

* runtime: switch default stack size back to 8kBRuss Cox2014-05-201-7/+0
| | | | | | | | | | | | | | | | | | | | | | The move from 4kB to 8kB in Go 1.2 was to eliminate many stack split hot spots. The move back to 4kB was predicated on copying stacks eliminating the potential for hot spots. Unfortunately, the fact that stacks do not copy 100% of the time means that hot spots can still happen under the right conditions, and the slowdown is worse now than it was in Go 1.2. There is a real program in issue 8030 that sees about a 30x slowdown: it has a reflect call near the top of the stack which inhibits any stack copying on that segment. Go back to 8kB until stack copying can be used 100% of the time. Fixes issue 8030. LGTM=khr, dave, iant R=iant, khr, r, bradfitz, dave CC=golang-codereviews https://codereview.appspot.com/92540043
