(still outstanding: changes to package publication workflow)
A package marked debugOnly in the package source is not to be bundled in production.
Moreover, if a package/app depends on a debugOnly package, that entire tree should
not be bundled. (But we should take it into account when figuring out versions!)
Does the following:
- In the catalog, we have a function that takes in a set of versions and a set of original
constraints and traverses it, recursively, to build a subset of versions that we *should*
bundle, and the corresponding subset of versions that we shouldn't (because they are either
debugOnly themselves or pulled in by debugOnly packages). (We do this in the catalog because
it is an addon onto the results of the constraint solver, tied deeply into our representation
of data)
- In the packageLoader, we keep track packages & versions that we should bundle, and also,
packages that we should exclude. We do this in the package-loader because, essentially, that's the
object that we use to keep the results of the constraint-solver, and we already propagate it to all
functions that care about it. (Possibly we should subsequently rename it later).
- In the compiler, when we figure out buildTimeDependencies, we ask if we need to bundle debug
builds. If not, we filter them out (see above). Also, when we actually build together unibuilds,
we don't touch the ones that the packageloader tells us to exclude (which ensures that they don't make
it into the final product).
- In the project, we keep track of whether this project is building in debug mode. That's because the project
is where we keep the state of our curent project that we are building, and if we are ever in the state of
building multiple things, then that's the code that we would need to touch (see also that we make a similar
assumption when solving constraints).
- Adds the option to keepthe project debug-build-free and calls it in commands when approporiate.
Previously, we would not write the versions file in this case because
project._recordVersions thought we were doing "run with a different
release temporarily"
Before, we were running the constraint solver with both the new and the
old constraint, which would fail if they were not simultaneously
satisfiable. (We were writing the right thing to disk if it succeeded,
at least.)
Drop the "at-least" constraint type entirely. It was not user-accessible
and was only used in the form ">=0.0.0" to represent a constraint with
no version constraint at all. This type of constraint is now called
"any-reasonable".
The definition of "any-reasonable" is:
- Any version that is not a pre-release (has no dash)
- Or a pre-release version that is explicitly mentioned in a TOP-LEVEL
constraint passed to the constraint solver
For example, constraints from .meteor/packages, constraints from the
release, and constraints from the command line of "meteor add" end up
being top-level.
Why only top-level-constrained pre-release versions, and not versions we
find explicitly desired by some other desired version while walking the
graph?
The constraint solver assumes that adding a constraint to the resolver
state can't make previously impossible choices now possible. If
pre-releases mentioned anywhere worked, then applying the constraints
"any reasonable" followed by "1.2.3-rc1" would result in "1.2.3-rc1"
ruled first impossible and then possible again. That's no good, so we
have to fix the meaning based on something at the start. (We could try
to apply our prerelease-avoidance tactics solely in the cost functions,
but then it becomes a much less strict rule.)
At the very least, this change should allow you to run meteor on a
preview branch like cordova-hcp without getting a conflict between the
prerelease package on the branch/release and the lack of an explicit
constraint in .meteor/packages on that package, because we are
reintepreting the .meteor/packages constraint as meaning "anything
reasonable" and the in-the-release version counts as reasonable.
The idea is that dotfiles in .meteor (like .id and .finished-upgraders)
aren't intended to be human-editable, whereas packages, release,
and versions are (although there are commands to edit them too).
Make sure that project._ensureDepsUpToDate does not get run mid-update,
since it might decide that various things are not compatible with the
packages in the current release. When the update command runs the
constraint solver explicitly, it passes ignoreProjectDeps, but implicit
calls can lead to an unhappy process.exit.
This before was just an uncaught exception. Now it's exit(1), which is
bad too. This should just use buildmessage, but for some reason that
doesn't work here.
We're going to make uniload use a different flavor of "complete" catalog
soon. So we need to reduce the number of singleton-ish references to
it.
Also, we need one PackageCache per catalog, so stop it from being a
singleton too.
Many of these (mostly in top level commands in commands-packages.js) are
not super well thought out: they use a new "doOrDie" helper to run some
function in a capture and exit if there are any messages. We really
need to get a little more thoughtful about the big picture of error
handling (combining "build" errors, network errors, catalog errors,
etc). But this at least allows the addition of more buildmessage
assertions.
At the very least, this ensures that if you edit a package.js in a local
package while "meteor run" is running, that instead of crashing the tool
it properly shows the buildmessage and lets you fix the issue.
Before, there were some random contexts (like 'test-packages') which
didn't print downloads. Now, the default is printing, and the exception
is the automatic background updater.
(Some of these bulk contexts should probably set silent and print their
own progress bar. And maybe even do paralellism...)
Generally clean up the tropohouse.maybeDownloadPackageForArchitectures
interface. Change it to take options, remove the vestigial return
value (though really, there needs to be better error handling...)
