* cmd/gc: blank methods are not permitted in interface typesChris Manghane2014-10-152-16/+2
| | | | | | | | | Fixes issue 6606. LGTM=rsc R=rsc CC=golang-codereviews, gri https://codereview.appspot.com/156210044
* cmd/gc: don't attempt to generate wrappers for blank interface methodsAnthony Martin2013-08-192-2/+36
| | | | | | | | | | Fixes issue 5691. R=golang-dev, bradfitz, daniel.morsing, rsc CC=golang-dev https://codereview.appspot.com/10255047 Committer: Rob Pike <r@golang.org>
* test: convert tests to run.go whenever possible.R?my Oudompheng2012-10-109-90/+97
| | | | | | | | | | | The other tests either need a complex procedure or are architecture- or OS-dependent. Update issue 4139. R=golang-dev, daniel.morsing, iant CC=golang-dev http://codereview.appspot.com/6618062
* test: expand run.go's errorcheck, make clear which bugs runRuss Cox2012-09-233-0/+9
| | | | | | | | | | | | | | | | Today, if run.go doesn't understand a test header line it just ignores the test, making it too easy to write or edit tests that are not actually being run. - expand errorcheck to accept flags, so that bounds.go and escape*.go can run. - create a whitelist of skippable tests in run.go; skipping others is an error. - mark all skipped tests at top of file. Update issue 4139. R=golang-dev, bradfitz CC=golang-dev http://codereview.appspot.com/6549054

* gc: implement == on structs and arraysRuss Cox2011-12-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | To allow these types as map keys, we must fill in equal and hash functions in their algorithm tables. Structs or arrays that are "just memory", like [2]int, can and do continue to use the AMEM algorithm. Structs or arrays that contain special values like strings or interface values use generated functions for both equal and hash. The runtime helper func runtime.equal(t, x, y) bool handles the general equality case for x == y and calls out to the equal implementation in the algorithm table. For short values (<= 4 struct fields or array elements), the sequence of elementwise comparisons is inlined instead of calling runtime.equal.

* gc: disallow map/func equality via interface comparisonRuss Cox2011-12-061-0/+39

| | | | | | | | | Had been allowing it for use by fmt, but it is too hard to lock down. Fix other packages not to depend on it. R=r, r CC=golang-dev http://codereview.appspot.com/5266054

* errchk: allow multiple patternsRuss Cox2011-08-162-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | // ERROR "pattern1" "pattern2" means that there has to be one or more lines matching pattern1 and then excluding those, there have to be one or more lines matching pattern2. So if you expect two different error messages from a particular line, writing two separate patterns checks that both errors are produced. Also, errchk now flags lines that produce more errors than expected. Before, as long as at least one error matched the pattern, all the others were ignored. Revise tests to expect or silence these additional errors. R=lvd, r, iant CC=golang-dev http://codereview.appspot.com/4869044
