The release action we are working conditionally executes based on the
version of `automerge-wasm` in the previous commit. We need to trigger
it even though the version has not changed so we roll back the version
in this commit and the commit immediately following this will bump it
again.
We have been listing all the files to be included in the distributed
package in package.json:files. This is tedious and error prone. We
change to using globs instead, to do this without also including the
test and src files when outputting declarations we add a new typescript
config file for the declaration generation which excludes tests.
The new text features are faster and more ergonomic but not backwards
compatible. In order to make them backwards compatible re-expose the
original functionality and move the new API under a `future` export.
This allows users to interoperably use both implementations.
The wasm codebase assumed that clients want to represent text as a
string of characters. This is faster, but in order to enable backwards
compatibility we add a `TextRepresentation` argument to
`automerge_wasm::Automerge::new` to allow clients to choose between a
`string` or `Array<any>` representation. The `automerge_wasm::Observer`
will consult this setting to determine what kind of diffs to generate.
The tsconfig.json was setup to not include the JS tests. Update the
config to include the tests when checking typescript and fix all the
consequent errors. None of this is semantically meaningful _except_ for
a few incorrect usages of the API which were leading to flaky tests.
Hooray for types!
The `SeekOp` query can produce incorrect results when the optree it is
searching only has visible ops on the internal nodes. Add some tests to
demonstrate the issue as well as a fix.
This is primarily useful when debugging documents which have been
corrupted somehow so you would like to see the ops even if you can't
trust them. Note that this is _not_ currently useful for performance
reasons as the hash graph is still constructed, just not verified.
Automerge CLI depends transitively (via and old version of `clap` and
via `colored_json` on `atty` and `ansi_term`. These crates are both
marked as unmaintained and this generates irritating `cargo deny`
messages. To avoid this, implement colored JSON ourselves using the
`termcolor` crate - colored JSON is pretty mechanical. Also update
criterion and cbindgen dependencies and ignore the criterion tree in
deny.toml as we only ever use it in benchmarks.
All that's left now is a warning about atty in cbindgen, we'll just have
to wait for cbindgen to fix that, it's a build time dependency anyway so
it's not really an issue.
* Don't panic on invalid gzip stream
Before this change automerge-rs would panic if the gzip data in
a raw column was invalid; after this change the error is propagated
to the caller correctly.
* Use AMbyteSpan for byte values
Before this change there was an inconsistency between AMmapPutString
(which took an AMbyteSpan) and AMmapPutBytes (which took a pointer +
length).
Either is fine, but we should do the same in both places. I chose this
path to make it clear that the value passed in was an automerge value,
and to be symmetric with AMvalue.bytes when you do an AMmapGet().
I did not update other APIs (like load) that take a pointer + length, as
that is idiomatic usage for C, and these functions are not operating on
byte values stored in automerge.
* More detailed instructions in README
I struggled to get the project to build for a while when first getting
started, so have added some instructions; and also some usage
instructions for automerge-c that show more clearly what is happening
without `AMpush()`
The error messages produced by various conversions in `automerge-wasm`
were quite uninformative - often consisting of just returning the
offending value with no description of the problem. The logic of these
error messages was often hard to trace due to the use of `JsValue` to
represent both error conditions and valid values - evidenced by most of
the public functions of `automerge-wasm` having return types of
`Result<JsValue, JsValue>`. Change these return types to mention
specific errors, thus enlisting the compilers help in ensuring that
specific error messages are emitted.
Transactions with no ops in them are generally undesirable. They take up
space in the change log but do nothing else. They are not useless
though, it may occasionally be necessary to create an empty change in
order to list all the current heads of the document as dependents of the
empty change.
The current API makes no distinction between empty changes and non-empty
changes. If the user calls `Transaction::commit` a change is created
regardless of whether there are ops to commit. To provide a more useful
API modify `commit` so that if there is a no-op transaction then no
changes are created, but provide explicit methods to create an empty
change via `Transaction::empty_change`, `Automerge::empty_change` and
`Autocommit::empty_change`. Also make these APIs available in Javascript
and C.
It's tricky to modify these structs with the fields public as every
change requires scanning the codebase for references to make sure you're
not breaking any invariants. Make the fields private to ease
development.
