ci: let GitHub Actions upload failed tests' directories

Arguably, CI builds' most important task is to not only identify
regressions, but to make it as easy as possible to investigate what went
wrong.

In that light, we will want to provide users with a way to inspect the
tests' output as well as the corresponding directories.

This commit adds build steps that are only executed when tests failed,
uploading the relevant information as build artifacts. These artifacts
can then be downloaded by interested parties to diagnose the failures
more efficiently.

4 years agoci: configure GitHub Actions for CI/PR
Đoàn Trần Công Danh [Fri, 10 Apr 2020 17:18:09 +0000 (00:18 +0700)] 
ci: configure GitHub Actions for CI/PR

This patch adds CI builds via GitHub Actions. While the underlying
technology is at least _very_ similar to that of Azure Pipelines, GitHub
Actions are much easier to set up than Azure Pipelines:

- no need to install a GitHub App,

- no need to set up an Azure DevOps account,

- all you need to do is push to your fork on GitHub.

Therefore, it makes a lot of sense for us to have a working GitHub
Actions setup.

While copy/editing `azure-pipelines.yml` into
`.github/workflows/main.yml`, we also use the opportunity to accelerate
the step that sets up a minimal subset of Git for Windows' SDK in the
Windows-build job:

- we now download a `.tar.xz` stored in Azure Blobs and extract it
  simultaneously by calling `curl` and piping the result to `tar`,

- decompressing via `xz`,

- all three utilities are installed together with Git for Windows

At the same time, we also make use of the matrix build feature, which
reduces the amount of repeated text by quite a bit.

Also, we do away with the parts that try to mount a file share on which
`prove` can store data between runs. It is just too complicated to set
up, and most times the tree changes anyway, so there is little return on
investment there.

exists, since we're using rebase-merge instead.

Since we don't really care which rebase backend is in use, let's just

pack-objects: flip the use of GIT_TEST_PACK_SPARSE

The environment variable GIT_TEST_PACK_SPARSE was previously used
to allow testing the --sparse option for "git pack-objects" in
the test suite. This allowed interesting cases of "git push" to
also test this algorithm.

Since pack.useSparse is now true by default, we do not need this
variable to _enable_ the --sparse option, but instead to _disable_
it. This flips how we work with the variable a bit.

When checking for the variable, default to a value of -1 for
"unset". If unset, then take the default from the repo settings,
which is currently 1. Then, the --[no-]sparse command-line option
will override either of these settings.

config: set pack.useSparse=true by default

The pack.useSparse config option was introduced by 3d036eb0
(pack-objects: create pack.useSparse setting, 2019-01-19) and was
first available in v2.21.0. When enabled, the pack-objects process
during 'git push' will use a sparse tree walk when deciding which
trees and blobs to send to the remote. The algorithm was introduced
by d5d2e93 (revision: implement sparse algorithm, 2019-01-16) and
has been in production use by VFS for Git since around that time.
The features.experimental config option also enabled pack.useSparse,
so hopefully that has also increased exposure.

It is worth noting that pack.useSparse has a possibility of
sending more objects across a push, but requires a special
arrangement of exact _copies_ across directories. There is a test
in t5322-pack-objects-sparse.sh that demonstrates this possibility.
This test uses the --sparse option to "git pack-objects" but we
can make it implied by the config value to demonstrate that the
default value has changed.

While updating that test, I noticed that the documentation did not
include an option for --no-sparse, which is now more important than
it was before.

Since the downside is unlikely but the upside is significant, set
the default value of pack.useSparse to true. Remove it from the
set of options implied by features.experimental.

4 years agogit-gui: create a new namespace for chord script evaluation

git-gui: create a new namespace for chord script evaluation

Evaluating the script in the same namespace as the chord itself creates
potential for variable name collision. And in that case the script would
unknowingly use the chord's variables.

For example, say the script has a variable called 'is_completed', which
also exists in the chord's namespace. The script then calls 'eval' and
sets 'is_completed' to 1 thinking it is setting its own variable,
completely unaware of how the chord works behind the scenes. This leads
to the chord never actually executing because it sees 'is_completed' as
true and thinks it has already completed.

Avoid the potential collision by creating a separate namespace for the
script that is a child of the chord's namespace.

4 years agogit-gui: reduce Tcl version requirement from 8.6 to 8.5

git-gui: reduce Tcl version requirement from 8.6 to 8.5

On some MacOS distributions like High Sierra, Tcl 8.5 is shipped by
default. This makes git-gui error out at startup because of the version
mismatch.

The only part that requires Tcl 8.6 is SimpleChord, which depends on
TclOO. So, don't use it and use our homegrown class.tcl instead.

This means some slight syntax changes. Since class.tcl doesn't have an
"unknown" method like TclOO does, we can't just call '$note', but have
to use '$note activate' instead. The constructor now needs a proper
namespace qualifier. Update the documentation to reflect the new syntax.

As of now, the only part of git-gui that needs Tcl 8.5 is a call to
'apply' in lib/index.tcl::lambda. Keep using it until someone shows up
shouting that their OS ships with 8.4 only. Then we would have to look
into implementing it in pure Tcl.
