This mostly affects Meteor core development (since for now, unipackage.load is
only used inside the meteor tools itself and only to load core packages, which
should be properly compiled in any Meteor release).
Package.register_extension API.
It didn't even actually work for producing JavaScript files (eg a
coffeescript-like package): see #1410. Package maintainers should have upgraded
to the more powerful 0.6.5 API by now anyway.
mongo-livedata uses galaxy package, which has a connection to galaxy that
doesn't get closed, which leads to commands hanging. We should probably have a
way to close galaxy's connection, but for now removing mongo-livedata at least
stops commands from hanging.
Allow dots in package names.
Change the internal representation of "package specs" inside Slice to be a
{package,slice} object instead of a "spec" string.
library.getSlices now can take EITHER a "spec" string or a {package,slice}
object.
Linker-created slice files also separate the slice name with a colon (so eg, you
get URLs like "/packages/livedata:tests.js" when running package tests). (Maybe
this should use a subdirectory instead?)
Specifically, don't watch until after serverHandle points to the NEW
process. This way, if the watcher files, we are sure to kill the new process,
not fail to kill it because serverHandle is still pointing at the old process or
no process. The old behavior led to sometimes failing to kill the server; while
it would eventually die due to failed keepalive, the new servers would also fail
due to EADDRINUSE.
This change is possible because unlike the only dependencyInfo, WatchSets are
completely self-contained (there's no "... and it should look like it did the
first time" involved).
While we're at it, make restartServer always stops the watcher, and clear some
variables after they're used.
Fixes#1247.
We call these the pluginProviderPackages because these are the packages that, if
they change, could affect the set of plugins available to this package (and thus
require it to be rebuilt).
