This refactoring commit changes runQueries() to calculate the set of
indices with non-empty custom queries early. Doing so allows us to check
early on whether there are any custom queries to run.
When the config specifies queries in external repositories and no other
queries and cli config parsing is enabled, the analyze job is not able
to find any queries to run and it fails. This PR fixes the problem.
Also add some logging statements when writing a copy of the user config
file.
This commit does a few related things:
1. Bumps the minimum version for cli config parsing to 2.10.6
2. Ensures that if cli config parsing is enabled, then remove repos
are _not_ downloaded by the action. It happens in the CLI.
3. Passes the `--external-repository-token-stdin` option to the CLI
and passes the appropriate token via stdin if cli config parsing is
enabled.
The tracer is very good at preserving itself, so unsetting the tracing-specific
variables from within a process will not end tracing for children of
that process.
The way the actions process model works means that we're running inside
a process for the entire build step that was launched with the tracer
variables set, so we'll have the tracer injected into the entire build
step and its children.
If we unset the variables in end-tracing, we will get into an intermediate
state: Not all variables in there are preserved by the tracer,
but the tracer is still active.
Usually, that wouldn't be a problem, but the autobuilders called from
the finalize step will suddenly run under a half-configured tracer.
Particularly, this half-configured tracer is unable to execute the dotnet
CLI without hangs, as the environment variable that prevents hangs for
dotnet on MacOS has been unset, but the tracer is still active.
This is an issue for the the go autobuilder, that invokes
user-provided build scripts in the hope of installing dependencies.
If that build script then invokes dotnet, it will hang.
This is only of concern for the Lua tracer that now implements proper
multi-language tracing: Previously, when encountering the go autobuilder,
the tracer disabled itself entirely, thus side-stepping any hangs.
In the new, multi-language tracing world, the tracer will stay active
as long as there is at least one other language that's been set up
for tracing.
Thus, we also get hangs when invoking the dotnet CLI through the go
autobuilder.
This commit prints diagnostic messages to the Actions log when debug
logging is enabled by passing `debug: true` to `codeql-action/init` or
enabling Actions step debug logging.
