cmd/go shells out to version control binaries to implement go get.

doc/install currently declares minimum supported OS versions for FreeBSD, macOS, and Windows, but only a minimum kernel version for Linux. Those requirements do not imply any particular version of the supported version control binaries, and those versions do matter in practice: in particular, git accrued a large number of flags in between 2.7 and 2.18 (#26653).

We should be explicit about which versions are supported for use with the go command.

Marking NeedsDecision to determine:

  • whether we want to specify versions, and
  • if so, what criteria to use to determine them.

Maybe it would be sufficient to say "git version X or later is known to work" (taken from the oldest git version commonly used in tests), instead of figuring out and keeping track of the oldest suitable version?

I would really hope that we work with whatever's in Debian Stable at least, which is currently 2.11.0: https://packages.debian.org/stretch/git

Re @mostynb's point it's fine to say we need 2.5 even if 2.4 appears to work too.

I also agree with Brad that essentially every git that's on a supported OS by default needs to work. That's been our practice to date.

essentially every git that's on a supported OS by default needs to work.

I think we all agree with that, but what does “supported OS” mean in this context?

Our current definition for Go on Linux, according to the install page, is just a kernel version and a specific exclusion for CentOS/RHEL 5.x. That doesn't tell us which distros (and which versions of which distros) we should use to determine “every git that's on a supported OS”.

To pick some examples:

  • Debian 8 “Jessie” is in its LTS phase. It shipped with Git 2.1.4, but has a backport of 2.11.0 available. Does that mean we need to support 2.1.4, or just 2.11.0?
    • Debian “Jessie” shipped with Go 1.3.
  • Ubuntu still supports Ubuntu 14.04 LTS, which shipped with Git 1.9.1. Does that mean we need to support Git 1.9.1?
    • From what I can tell, Ubuntu 14.04 LTS is ~9 Ubuntu releases ago. It shipped with Go 1.2, with a backport to Go 1.3.
  • Slackware 14.0 has not been EOL'd yet, and it shipped with kernel 3.2.29 and Git 1.7.12. Does that mean that we need to support Git 1.7.12?

The table at https://en.wikipedia.org/wiki/Git#Release says that Git 2.12 and older are themselves no longer maintained. (However, I'm having trouble finding any supporting documentation in the Git release notes or mailing list.)

I suppose we could always vendor something like https://github.com/src-d/go-git . Not that I'm seriously suggesting that.

When it comes to GNU/Linux distros, I suggest that we can plausibly take CentOS as the trailing edge. CentOS is specifically adopted by people who want long term stability and who don't want to hack on their systems. We have decided that CentOS 5 is too old, so let's take CentOS 6 as the oldest version we want to support. CentOS 6 comes with git 1.7.1. I have no idea what is involved here: can we support git 1.7.1 and later without unreasonable effort?

It's probably inevitable that we go that route at some point. Maybe we should've from the beginning, in retrospect.

If CentOS is an OS that people deploy to but don't develop on, perhaps we don't need to care about its git version, assuming they just get their packaged binaries via Docker or scp or whatever.

But then one could make the same (incorrect?) assumption for Debian Jessie and Ubuntu 14.04 LTS, that people are more likely to deploy there than hack there themselves. But I just don't know if that's true.

I wish we had an opt-in mechanism like Debian's popcon (https://popcon.debian.org/) to let us collect statistics from Go users on their OS/versions/tool versions.

GitHub suggests using 1.7.10 in their help[*]:
"There's no minimum Git version necessary to interact with GitHub, but we've found version 1.7.10 to be a comfortable stable version that's available on many platforms."

[*] https://help.github.com/articles/https-cloning-errors/

If a particular minimum tested git version is selected, perhaps it could be tested on a bot without distribution-specific git packages installed? That way the test would not be tied to a specific distribution, and any git version requirement changes would at least need to be made consciously from that point onward.

I wish we had an opt-in mechanism like Debian's popcon (https://popcon.debian.org/) to let us collect statistics from Go users on their OS/versions/tool versions.

Sounds like an interesting side project, but would require some thought to avoid privacy/GDPR/etc issues.

FWIW I don't think vendoring go-git is a good idea at all and I don't think it's inevitable we end up there. We should use the same VCS tools our users are, not ship our own slightly different tools with different bugs. Back before we started invoking git again we had a whole bunch of "git works why doesn't your tool?" kinds of bugs. I like that those are by definition gone.

Maybe this thread is not really focused on the right thing. Maybe we should define which Linux distros we support and then it's implied which git versions we need to support. (And someone could figure out the exact implication.)

Brad suggests:

  • latest Ubuntu
  • latest Debian stable
  • latest RedHat Fedora
  • oldest Ubuntu LTS still supported by Ubuntu

Anything else?

@ianlancetaylor ianlancetaylor commented Aug 14, 2018

CentOS, as mentioned above. We have already chosen to not support CentOS 5, because the kernel is too old. What about CentOS 6? (It's clear from the number of bug reports we get about CentOS 5 that people who use CentOS do care about Go.)

@bradfitz bradfitz commented Aug 14, 2018

@ianlancetaylor, do you have any sense for whether people develop on CentOS vs just deploying to CentOS?

If we only care that resulting binaries work well on CentOS 6, that's easier than making sure "go get" and friends work with old git versions.

Maybe we should define which Linux distros we support and then it's implied which git versions we need to support.

This feels like the most practical thing to do, not least because we can use a number of Docker/other images as test rigs, e.g. #26988 (comment).

oldest Ubuntu LTS still supported by Ubuntu

I think this covers Travis and CircleCI. Put another way, I think it's worth making sure we have coverage of the major (to be defined) CI systems out there to ensure they are covered, and add their images/base images to the list if not.

Even if there was to be a list of Linux distros enumerated, it seems there would still be a need to pick a minimum supported git version to handle Windows, Macs, etc.?

It seems picking a git version would be more direct than picking a list of distros, including given the most immediate triggering event here seems to variability in git behavior across old versions.

For a developer who is "stuck" with an older environment for whatever reason, it is probably easier to upgrade git than to switch distros or upgrade their OS, which means having the restriction based on git might be friendlier to Go users.

That said, perhaps the conclusion ends up being both a git version and a list of distros get selected?

If there is a list of Linux distros enumerated, I would hope it would be made extremely clear that it is not a contraction of where Go code can run once compiled but rather a contraction of where the Go tooling is supported.

In terms of CentOS, I've definitely seen a common pattern of RHEL for production with CentOS for dev/QA (because very close to RHEL).

However things are end up being characterized in terms of what is officially supported, a related question would be whether or not anything is validated, and if so, whether a failing result is a warning vs. error vs. ___.

@bcmills can you describe what sorts of things break when using an older version of a VCS tool?

Also would the go tool enforce or otherwise check the version and give a helpful error message?

can you describe what sorts of things break when using an older version of a VCS tool?

The typical failure mode is that we add some flag (e.g. to disable one of the many ways that user settings can leak in to the behavior of git archive) and it turns out that the flag isn't present in some older version still in use. Then that whole command fails, or (less frequently) git ignores the flag and our fix is ineffective on that version.

Also would the go tool enforce or otherwise check the version and give a helpful error message?

If we know some version that we definitely don't support, we could emit a helpful error.
If we know what version we do support, then perhaps we could emit a helpful message only if the command fails (analogous to the behavior for #28221).

As far as proposal process, everyone seems to agree we should do this - define which VCS we support. The exact details can be worked out as a regular issue. (See also #26746 (comment) above.)

I have no idea if we use - from the go command - git options added since Git 1.7.1. One option is to say that CentOS 6 can be a deploy target but not a development target (at least for 'go get').

Can someone find out whether 'go test cmd/go/...' succeeds on CentOS 6 with git installed?
(If there's no git at all, the tests will be skipped entirely.)

@bcmills bcmills commented Dec 12, 2018

I spun up a CentOS 6 image and installed git and gcc at the default versions using yum install, then installed go1.11.2 from the pre-packaged binaries on golang.org and ran go test cmd/go/....

There were many failures, mostly related to Git commands.

I'm doing to try from HEAD next; I expect about the same number of failures but perhaps more-useful error messages.

I wanted to get a view of what might be a sensible cut-off for a minimum supported git version based on what modules users are using in practice.

Based on spending a couple of hours on this today, my observations included:

  1. A large number of complaints about git versions >= 2.7.4 not working.

    • As far as I am aware, these were all were subsquently resolved.
  2. A small number of complaints about 1.x git versions not working, such as 1.7.1, 1.7.2, 1.7.x, 1.9.1.

    • As far as I am aware, these were not resolved, aside from workarounds like asking people to upgrade their versions of git, which seems to have at least reduced the noise level around these 1.x versions of git.
  3. No complaints about git versions in the range > 1.9.1 and < 2.7.4.

Just because I found no complaints for a version range does not mean there were no complaints, but that sampling of results might suggest where the largest weight might be.

I ended up reading a small number of older issues carefully, and skimming comments from a larger set of issues:

  • I went back to an older snapshot of the Modules wiki. During vgo and 1.11 beta/rc phase, the wiki had been tracking a set of common issues people were frequently hitting due to older versions of git.
  • In order to cast a broader net, I then also ran some regexes against GitHub comments via maintner to try to find comments mentioning git versions.

Here is a programatically generated list of mentions of git versions from comments in issues with the modules tag. This is surely an incomplete view, but might at least give a flavor:

44 mentions of git versions across 16 issues
  • #26134: "git version 2.11.0"
  • #26353: "yes the git version is 2.16.1.windows.4."
  • #26353: "I am guessing due to git version 2.7 which is there in 16.04. The fix for that is in latest master. Either try with master or wait for an RC to get out."
  • #26353: "Note that your git version still needs to be greater than 1.7.2. If it is, then this is most probably a different issue. Please open a new bug with the exact steps to reproduce your issue. Thank you."
  • #26380: "git version 2.18.0.windows.1"
  • #26501: "-c paramater in "git log" means something different: https://git-scm.com/docs/git-log/2.6.5#git-log--c"
  • #26501: "git version 2.7.4"
  • #26501: "My git version is 2.7.4."
  • #26501: "--no-show-signature was introduced in git 2.10.0, roughly 2 years ago."
  • #26501: "The problem come from git version i has 2.8.2 and failed, i uprade to 2.18 and it's working."
  • #26511: "It seems this may be a dupe of #26501 I didn't catch that the --no-show-signature flag didn't exist in Git until 2.10.x and updating my git config to set that to false with git 2.7.4 didn't change anything (seems Git silently ignored the invalid setting)."
  • #26526: "EDIT: Do you have an old git version < 2.10 ? Check #26501"
  • #26594: "> My git version is 2.7.4."
  • #26594: "As far as I can tell, this is exactly the same setup as my CI build; same docker image, git version (2.11.0) etc."
  • #26594: "Does anyone have any idea what is wrong with git 2.7.4? Does it not support --depth=1?"
  • #26594: "for what its worth git 2.7.4 and go head works fine for me."
  • #26594: "git version 2.7.4"
  • #26594: "However, rogpeppe, with a standard Ubuntu 16.04 setup (git 2.7.4) can reproduce the exit code 1."
  • #26594: "I could move off git 2.7.4 but as it's the default version you get when using Ubuntu 16.04 I think it's important that Go works correctly with that version."
  • #26594: "I also can't reproduce the exit code 1 using git 2.7.4:"
  • #26594: "I just tried one of those git commands and as it happens it does return exit code 1 without printing any error, so perhaps the problem is with git itself. I am using git 2.7.4."
  • #26594: "I'm seeing the aforementioned behaviour on CircleCI v2 (which has git 2.11.0), so not an uncommon setup people will be using. CircleCI globally sets url.ssh://git@github.com.insteadof=https://github.com, hence how this comes about."
  • #26594: "The build was failing because, ultimately, the following git (2.11.0) command failed:"
  • #26594: "Using git 2.11.0 (because this particular command is not a problem with more recent git versions) and assuming an appropriate ssh setup:"
  • #26632: "git version 2.7.4"
  • #26695: "I don't think it's a git issue, because I am running git 2.18.0 as well."
  • #26695: "I think it is some Go caching issue, because it affects one user but not other newer user, both on the same system. Both users share system-wide go 1.11beta2 and git 2.18.0."
  • #26695: "This seems to work for me (with git 2.18.0, which suggests that sillyousu's theory is correct)."
  • #26713: "gv="git version 2.7.4""
  • #26754: "It appears that git 2.7.4 can't resolve one of the converted versions, whereas git 2.18.0 can. (See also #26653.)"
  • #27153: "git version 2.10.0"
  • #27153: "git version 2.17.1"

While I am sure you don't want a bunch of people saying which distro they use, I will call out mine since it was questioned above. My company currently is developing and deploying on CentOS/Redhat 6, because of its long term stability.

Also from a developers perspective, It would be a lot easier to see which OSes are supported period, rather than which is supported for development vs deployment.

Change https://golang.org/cl/191978 mentions this issue: cmd/go/internal/get: remove '--' separator from 'git ls-remote' command

gopherbot pushed a commit that referenced this issue Aug 27, 2019
'git ls-remote' started recognizing the '--' separator at some point
after 2.7.4, but git defaults to version 2.7.4 on Ubuntu 16.04 LTS,
which remains supported by Ubuntu until April 2021.

We added '--' tokens to most VCS commands as a defensive measure in
CL 181237, but it isn't strictly necessary here because the 'scheme'
argument to our template is chosen from a predefined list: we can
safely drop it to retain compatibility.

Fixes #33836
Updates #26746
