(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.
Fixes#2488.
Assets added via "no handler" already have their source files added to
`sources` via the `sources.push(relPath)` in the sourceItems loop, and
assets added via a handler should not appear as source files themselves
--- the file that triggered the handler should!
This fixes packages like `mizzao:build-fetcher` which add static
assets via a plugin.
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.
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.
- The checkout catalog.uniload now does not uniload a resolver, and
instead just has a trivial implementation of resolveConstraints.
(The 'built' catalog.uniload already didn't use the resolver.)
- catalog.complete.resolveConstraints now throws an error if there's
no resolver; this is OK, because creating the resolver now only
uses the distinct catalog.uniload, so there's no recursion issue.
- don't record version dependencies in packages during uniload (this
protects against using release.current before it is initialized)
- PackageLoader should never download packages during uniload (this
protects against using catalog.uniload.isLocalPackage before it is
initialized)
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.
Regression introduced by the CSS watching code (specifically, f230eba62)
by the sourceIsWatched check. We need to be able to tell the difference
between "source handler didn't do anything because there was an error"
and "source handler didn't do anything because it's web-specific and
this is an os arch".
A simple fix would have been to interpret compileStep.error as
"sourceIsWatched = true", but I didn't think of that until after doing
it the slightly more complicated but more precise way :)
Also, ensure that if the runner rebuilds the client and there's an
error, it properly kills the app process (and the watchers and the
keepalive interval, etc).
