Go 1.21 and dependencies update

• go 1.21
• protoc-24.2
• google.golang.org/protobuf v1.31.0

[masher] Support ARM64

masher now supports building ARM64. It does so by default if uname -m says it is on arm64, or if the --arm64 flag is passed in. On an arm64 machine the default can be overridden with --amd64 or --x86_64 to build again an x86_64 binary.

Go 1.20 compatibility

Yet again, the internal sort functions have changed.

Go 1.19 compatibility

This update is to add compatibility with go1.19.

v0.2.12: Wider GOOS support

I’ve written lib/files/clipboard to cover more than just linux, windows, and darwin.

Not supported: android, nacl, plan9, and zos but at least they should not compile-time error anymore.

The OSes: dragonflybsd, freebsd, linux, netbsd, openbsd and solaris still require you to have either xclip or xsel installed. If you do not have them installed, then the clip: and clipboard: URI schemes will always return os.ErrNotExist.

v0.2.11: Avoiding UDP truncated reads.

Using files.Copy with a UDP source had a problem where it was sometimes making reads with small buffers, which could lead to truncation of packets. This was solved in two parts:

• Datagram readers are now a buffered stream fed from individual packet reads. This means all files.Reader can be assumed to operate compatibly as a stream. (i.e. it will not break if used with io.LimitReader)
• files.Copy now uses a fuzzyLimitedReader that does not narrow the Read buffer to ensure only at most N bytes are read from its underlying source.

As a result of the datagram readers now being buffered, they now also have a receiver method of ReadPacket(buf []byte) (n int, err error) which does not ever buffer its reads, so that it can be type-asserted by packet-aware code to avoid potentially going through the buffer.

v0.2.10: Reworked lib/files/socketfiles code

The socket code was reworked to fix some bugs, and also be better engineered. See PR-16 for more details.

v0.2.9: Go 1.14 bump

• Brings in go1.14 for masher, and expect go1.1.4 from go.mod.
• Updates go.mod dependencies to newest versions.

v0.2.8: Clean up

Mostly the go.mod file is cleaned up. A few additional bug fixes also.

v0.2.7: Updates for go1.13 and protoc 3.9.2

Updates masher scripts and build directives:

• Uses go1.13 for building
• Uses protoc 3.9.2 for protocol buffers
• Injects main.Version from git tags
• Detects vendoring and short-circuits downloading dependencies and builds with -mod=vendor
• includes sumdb support
• Pass-through of GOPRIVATE into underlying docker container.

There are no updates to the lib/ portion of this repository from this release.
