CircleCI tests will fail for this commit, since these changes do not
address the problem that the module.useNode() stub imports the ESM code
using require. I will fix the tests properly in a later commit.
Although the Meteor jquery package is no long a core package (and thus is
not tied to the Meteor release), it seems like a good idea to nudge folks
towards installing jquery from npm, instead of relying on the very old
version (1.12.1) residing in meteor/packages/non-core/jquery/jquery.js.
Closes#10289.
The meteor/tools/isobuild/resolver.js changes are the static half of the
puzzle. The runtime half was implemented in install@0.13.0 with this
commit: 233aa75ce3
When I implemented support for the "module" entry point in package.json
files for client code in #10541, I modified PackageSource#_findSources to
include files found in node_modules that need to be compiled, but my
implementation considered only "local" node_modules directories, like the
one in the application root directory, while neglecting the private
.npm/package/node_modules directories that many Meteor packages have.
This commit includes .npm/**/node_modules when _findSources is scanning a
Meteor package, which should solve issues like #10544, where a Meteor
package imports an npm package that was installed with Npm.depends, and
that npm package has a "module" field in its package.json file, pointing
to an ESM entry point module, but the ESM syntax was not appropriately
compiled, leading to parse errors like "Unexpected token export".
Before lazy compilation was introduced in Meteor 1.7 (#9983), including
the node_modules directories of Meteor packages would likely have been a
big problem for build performance, since there would be that many more
modules to compile. It's still worth making sure this change doesn't
regress build performance for other reasons, but I'm reasonably confident
lazy compilation will save us here, unless there are just too many npm
packages installed via Npm.depends that export ESM modules.
Supporting "module" in package.json for server code is not advisable
because Node.js will be adopting the "type":"module" convention instead,
and in the meantime we need to maintain consistency with Node's module
resolution rules, which only currently pay attention to "main":

Fixes#10393.
Bumping compiler.BUILT_BY and LINKER_CACHE_SALT because
PR #10414 changes the behavior of the build system in a subtle way that
does not automatically trigger recompilation.
New Meteor apps have the following meteor.testModule in their package.json
files by default
"meteor": {
"testModule": "tests/main.js"
}
When meteor.testModule is defined, it determines the test entry point when
running the `meteor test` command, ignoring legacy file naming conventions
like *.tests.js or *.app-tests.js.
The package-source.js code changed by this commit was incorrect because it
ignored those specially-named test files even when running tests, which
was a problem if the meteor.testModule tried to import them explicitly,
because they would not be properly compiled.
If you're using meteor.testModule, the distinction between `meteor test`
and `meteor test --full-app` matters a bit less, since the test entry
point will be the same for both modes, though you can still check
Meteor.isTest and Meteor.isAppTest at runtime to control test behavior.
Should resolve#10233, reported by @klaussner.
Previously, if a compiler plugin called inputFile.addJavaScript multiple
times with different { path } strings, Meteor would allow importing all of
those modules at once by importing the original source module identifier,
by synthesizing a new source module containing a series of re-exports for
each of the generated modules.
Preserving this behavior is important for backwards compatibility, since
some compiler plugins still generate files like "module.ext.js" given an
input file named "module.ext", so Meteor tries to make those modules
interchangeable/synonymous.
However, if the compiler plugin explicitly calls inputFile.addJavaScript
with the original source path, then it would be a mistake to modify the
contents of that module, so Meteor will now leave the contents of that
explicit source module unmodified, rather than using it as a catch-all way
to import other generated modules.
