It used to create a directory with an underscore instead of a colon
Now, it just removes the prefix.
In cases where the name of the package has more than one colon or starts or ends
witha colon, we report an error.
In particular, ban leading `-`, trailing `.`, and `..` anywhere.
This backport commit drops the changes to constraint-solver and adds a
History.md note.
Verified manually that `meteor update asdf.` displays an error,
not a stack trace.
Include the offending name in all error messages (as we do for
invalid versions).
In the return value, `name` has been changed to `package`,
and `vConstraint` is now `versionConstraint`.
`constraint.package` is better than `constraint.name`, where
`constraint` is a PackageConstraint. It's also more consistent
with functions like parsePackageAtVersion which return an object
like `{package, version}`.
`vConstraint` was too cryptic.
Changes were discussed with Glasser in a code review.
Troposphere does not call parseConstraint or work with constraint
objects, so it doesn't need to change.
This is a breaking change to the package-version-parser API (or one
method of it, at least), but it is considered an internal API so we
are not worrying too much about it.
Fill in all packages without README.md files with a short
README.md mentioning that this is an internal Meteor package.
Break up the top paragraph of a couple of existing README.md
files to be proper long description.
There is more work to do here, involving line wrapping and the like.
You can still include them on the client, but they don’t work in
Safari 4 and IE 8 because semver.js uses ES 5 methods including
String#trim, Array#map/filter/forEach, and possibly others.
This should fix any unit test failures in these packages.
PackageResolver no longer loads data from the Catalog. Instead, it
tells CatalogLoader what to load, and it sets up the Resolver based
on what it finds in the CatalogCache.
PackageResolver now creates the Resolver inside resolve(…). If the tool
were to invoke resolve(…) multiple times on the same PackageResolver
(which it doesn’t at the moment), the CatalogCache would persist, but
not the Resolver. (Note that PackageResolver#resolve makes multiple
calls to the same Resolver#resolve internally.)
The purpose of this change is to stop using Resolver to store the
dependency graph. Resolver will be replaced with a logic-solver-based
implementation that will not represent the graph as is, but instead
encode the graph as a satisfiability problem. Meanwhile, CatalogCache
is better at storing the graph than Resolver was, because it is easy
to populate, query, and serialize.
This change brings us back to a functional “devel”.
This is a breaking change to package-version-parser.
A PackageConstraint used to look like this:
```
{ name: String,
constraintString: String,
constraints: [{version: String|null,
type: String}]}
```
Now it looks like this:
```
{ name: String,
constraintString: String,
vConstraint: {
raw: String,
alternatives: [{versionString: String|null,
type: String}]}}
```
Where (vConstraint instanceof VersionConstraint) and
(vConstraint.raw === constraintString).
This achieves several desirable changes at once.
* `constraint.constraints` for the disjuncts in “1.0.0||2.0.0”
was confusing. `alternatives` is better.
* Having a class for VersionConstraint will come in handy because
we can add methods to it, and we can use it in the constraint
solver to represent the problem statement.
* The names “vConstraint” and “versionString” are a little verbose,
but there really shouldn’t be a lot of code that dives into this
structure, and I really wanted to avoid anyone ever writing:
`constraint.constraint.alternatives[0].version`, and then wondering
what sort of object that was (not a parsed PackageVersion! we could
parse eagerly but that might be slow).
Mostly I just made parseConstraint clearer and gave the return value a
prototype.
There are new unit tests, and the existing ones have been given much
better names.
PV.parseConstraint also now optionally takes two arguments, a package name and a version constraint. We can eventually propagate this feature to the tool and stop concatenating with “@” so much.
I’m referring to “foo@=1.0.0” as a PackageConstraint and “=1.0.0” as a version constraint. I’ll probably add a VersionConstraint class too.
Despite the name “package-version-parser,” PVP didn’t really provide a way to parse a package version. With this change, if you want to get the minor version of “1.2.3_4”, for example, you can just write `PV.parse(“1.2.3_4”).minor`. This simplifies the internals of PVP as well.
When you parse a version, you now get an instance of PackageVersion with a documented set of fields.
Also, make PVP work on the client. When called directly from the tool, semver is loaded the same way as before. When PVP is used as a package, it uses a copy of semver v4.1.0 kept inside the package.
This change is intended to be 100% behavior-preserving.
