add golang 1.19 and update of copyright year

[Hammond95]

What has changed

• patched a bug in the python script fetching go binaries urls:

  gimme/fetch-object-urls

  Line 22 in 01e9428

  def _fetch_links(base_url=DEFAULT_BASE_URL, max_fetch=20):

  
  This code probably should be improved since the links grow in time.

• updated copyright:

  gimme/gimme

  Line 58 in 01e9428

  readonly GIMME_COPYRIGHT="Copyright (c) 2015-2022 gimme contributors"

• add go 1.19 to version list:

  gimme/gimme

  Line 288 in 01e9428

  local versions=("1.19" "1.18" "1.17" "1.16" "1.15" "1.14" "1.13" "1.12" "1.11" "1.10" "1.9" "1.8" "1.7" "1.6" "1.5" "1.4")

• add a better method to compare version numbers in runtests:

  gimme/runtests

  Line 21 in 01e9428

  version() { echo "$@" | tr -d '[:alpha:]' | awk -F. '{ printf("%d%03d%03d%03d\n", $1,$2,$3,$4); }'; }

  
  

  gimme/runtests

  Line 90 in 01e9428

  if [[ $(version "$v") -lt $(version 1.5.0) && "${v}" != "tip" && "${v}" != "master" ]]; then

• updated shfmt and shellcheck versions:

  gimme/.travis.yml

  Lines 14 to 15 in 01e9428

  	- SHFMT_VERSION="v3.5.1"
  	- SHCHK_VERSION="v0.8.0"

• expanded matrix in order to test separately failing builds:

  gimme/.travis.yml

  Lines 23 to 51 in 01e9428

  	matrix:
  	- env:
  	TARGET: "native"
  	GO_VERSIONS: "$(sed -n -e '/^[^#]/p' < .testdata/sample-binary-$UNAME) $(sed -n -e '/^[^#]/p' < .testdata/source-$UNAME)"
  	addons:
  	apt:
  	packages:
  	# install cross compilers for cgo support.
  	- gcc-arm-linux-gnueabi
  	- libc6-dev-arm64-cross
  	- env:
  	TARGET: "arm"
  	GO_VERSIONS: "master"
  	addons:
  	apt:
  	packages:
  	# install cross compilers for cgo support.
  	- gcc-arm-linux-gnueabi
  	- libc6-dev-arm64-cross
  	- env:
  	TARGET: "arm64"
  	GO_VERSIONS: "$(sed -n -e '/^[^#]/p' < .testdata/sample-binary-$UNAME) master"
  	GIMME_DEBUG: "true"
  	addons:
  	apt:
  	packages:
  	# install cross compilers for cgo support.
  	- gcc-arm-linux-gnueabi
  	- libc6-dev-arm64-cross

  
  I think this could be a better approach also if we want to test on different architectures and different env variables.

• ran make lint which performed minor syntax changes

• ran make update-binary-versions to update links and versions in files of the test data.

I am asking others maintainers support here, because I don't know why test fail... maybe they should be updated, but I need more context.

[Hammond95]

I think that #204 is trying to achieve my same result, at the moment both build are in failed state.

Mine at the moment is 2 out of 3.

should we collaborate to get it 3 out of 3?

Mine fails for some reason I couldn't understand on installing go 1.19.1 with target arm64. It does install it on travis native arch, so the go binary is not executable.

But as far as I understood, gimme is expected to try to rebuild go using cross compilers and this way it should then work on this architecture too.

But these are just what I got, I may be wrong. I am here again asking for some clarification by the official maintainers of the project.

[Hammond95]

Could this also be related to #154?

[Hammond95]

@philpennock I tried to use GIMME_CC_FOR_TARGET: "arm-linux-gnueabi-gcc" for cross compilation, as you had suggested on #154, but the build failed anyways... any other idea?

[Hammond95]

The only test that fails on this branch is the installation on ARM64 using cross compilation. I don't know if this has ever worked.

I will stop here with developments unless someone else (possibly a travis-ci maintainer), points out to some solution/suggestion/way to go.

---

If someone thinks this should be merged, I would go for a squash merge, since I did many commits to try different stuff.

[Hammond95]

One thing that makes me think that this has never worked is that the error is the following:

./runtests: line 102: /home/travis/.gimme/versions/go1.19.1.linux.arm64/bin/go: cannot execute binary file: Exec format error
./runtests: line 98: /home/travis/.gimme/versions/go1.19.1.linux.arm64/bin/go: cannot execute binary file: Exec format error

env file is created and also the go binary is downloaded. The go binary is probably compiled for arm64 architecture and doesn't work on the native amd architecture.

@Hammond95 Hey, thanks for your contribution. @mustafa-travisci Could you take a look? It seems that you've been working on similar issue.

[Hammond95]

I also wanted to point out the following issues:
#166
#154
#42

still open that may be related to our problem of cross compilation.

[Hammond95]

@r-arek I haven't received any feedback from @mustafa-travisci.

It seems to me that the project has always had cross compilation issues (see #166 #154 #42).

We should probably solve these issue on a dedicated PR.

[Hammond95]

@r-arek @mustafa-travisci

I don't want to bother anyone here, but I think this PR adds the functionality to download go1.19, so it could be ok to merge it.

The cross-compiling functionality as far as I can see, has never worked well, so that problem should be addressed in a different PR.

[Hammond95]

@r-arek Is the project dead?

It's been more than a month and I didn't receive any feedback :(
