runtime: unify mutex code across OSes · ee24bfc0

Dmitriy Vyukov authored Nov 02, 2011

The change introduces 2 generic mutex implementations
(futex- and semaphore-based). Each OS chooses a suitable mutex
implementation and implements few callbacks (e.g. futex wait/wake).
The CL reduces code duplication, extends some optimizations available
only on Linux/Windows to other OSes and provides ground
for futher optimizations. Chan finalizers are finally eliminated.

exec: introduce ExitError · 451a1fa4

Russ Cox authored Nov 02, 2011

The existing code uses *os.Waitmsg as an os.Error,
but *os.Waitmsg is really just a stringer.

Introduce an explicit error type for the real error.

Not to be submitted until just before error goes in;
the gofix for error updates type assertions
        err.(*os.Waitmsg)
to
        err.(*exec.ExitError)

The seemingly redundant String method will become
an Error method when error goes in, and will no longer
be redundant.

gofix: error fix · 758200f2

Russ Cox authored Nov 02, 2011

To make the error fix more useful, expand typecheck to gather
more information about struct fields, typecheck range statements,
typecheck indirect and index of named types, and collect information
about assignment conversions.

Also, change addImport to rename top-level uses of a to-be-imported
identifier to avoid conflicts.  This duplicated some of the code in
the url fix, so that fix is now shorter.
