Martin Atkins	783a07d9e8	build: Use Go 1.19 ... Go 1.19's "fmt" has some awareness of the new doc comment formatting conventions and adjusts the presentation of the source comments to make it clearer how godoc would interpret them. Therefore this commit includes various updates made by "go fmt" to acheve that. In line with our usual convention that we make stylistic/grammar/spelling tweaks typically only when we're "in the area" changing something else anyway, I also took this opportunity to review most of the comments that this updated to see if there were any other opportunities to improve them.	4 years ago
Martin Atkins	c23a7fce4e	lang/funcs: Preserve IP address leading zero behavior from Go 1.16 ... Go 1.17 includes a breaking change to both net.ParseIP and net.ParseCIDR functions to reject IPv4 address octets written with leading zeros. Our use of these functions as part of the various CIDR functions in the Terraform language doesn't have the same security concerns that the Go team had in evaluating this change to the standard library, and so we can't justify an exception to our v1.0 compatibility promises on the same sort of security grounds that the Go team used to justify their compatibility exception. For that reason, we'll now use our own fork of the Go library functions which has the new check disabled in order to preserve the prior behavior. We're taking this path, rather than pre-normalizing the IP address before calling into the standard library, because an additional normalization layer would be entirely new code and additional complexity, whereas this fork is relatively minor in terms of code size and avoids any significant changes to our own calls to these functions. Thanks to the Kubernetes team for their prior work on carving out a subset of the "net" package for their similar backward-compatibility concern. Our "ipaddr" package here is a lightly-modified fork of their fork, with only the comments changed to talk about Terraform instead of Kubernetes. This fork is not intended for use in any other future feature implementations, because they wouldn't be subject to the same compatibility constraints as our existing functions. We will use these forked implementations for new callers only if consistency with the behavior of the existing functions is a key requirement.	5 years ago
