slices: avoid mutating elements between length and capacity in Grow Repeatedly calling Grow on a slice with sufficient capacity should effectively be a noop. However, this was not the case since it would zero out the elements between the length and capacity. Avoid that behavior to ensure Grow remains cheap in the common case. Also provide a workaround for golang/go#53888 to ensure that the number of allocations when growing is always 1. Fixes golang/go#53853 Change-Id: Id52c0d50ae9a97fe8af9acfeb666360859f336c0 Reviewed-on: https://go-review.googlesource.com/c/exp/+/417494 Reviewed-by: Daniel Martà <mvdan@mvdan.cc> TryBot-Result: Gopher Robot <gobot@golang.org> Reviewed-by: Eli Bendersky <eliben@google.com> Reviewed-by: Ian Lance Taylor <iant@google.com> Run-TryBot: Joseph Tsai <joetsai@digital-static.net>
This subrepository holds experimental and deprecated (in the old
directory) packages.
The idea for this subrepository originated as the pkg/exp
directory of the main repository, but its presence there made it unavailable to users of the binary downloads of the Go installation. The subrepository has therefore been created to make it possible to go get
these packages.
Warning: Packages here are experimental and unreliable. Some may one day be promoted to the main repository or other subrepository, or they may be modified arbitrarily or even disappear altogether.
In short, code in this subrepository is not subject to the Go 1 compatibility promise. (No subrepo is, but the promise is even more likely to be violated by go.exp than the others.)
Caveat emptor.
