# Changelog
|
|
|
|
## 0.7.0
|
|
|
|
- Migrate to null-safety.
|
|
|
|
## 0.6.0
|
|
|
|
- Update to latest args, path, meta dependency.
|
|
|
|
## 0.5.6
|
|
- Fix for flutter/flutter#76313 causing issues with profiles containing
|
|
WSRs serialized as smi-s instead of actual WSR objects.=
|
|
|
|
## 0.5.5
|
|
- Add `deps-display-depth` (`-d`) flag for `summary` command to make the display
|
|
depth of outputted dependency trees configurable.
|
|
- Rename `deps-collapse-depth` (formerly `-d`) flag for `summary` command to
|
|
`deps-start-depth` (now `-s`).
|
|
- Add `generateCallGraphWithDominators` method that generates a `CallGraph`
|
|
object from precompiler trace.
|
|
|
|
## 0.5.4
|
|
- Fix bug causing name clash for Type class.
|
|
|
|
## 0.5.3
|
|
- Add `compareProgramInfo` that takes in two program info objects and outputs
|
|
a `Map` object containing the diff data.
|
|
|
|
## 0.5.2
|
|
- Add support for package paths that look like `package:foo.bar.baz/src/foobar.dart`
|
|
- Move `commands` back to lib.
|
|
|
|
## 0.5.0+1
|
|
- Fix broken package by moving non-executable file out of bin/ directory.
|
|
|
|
## 0.5.0
|
|
- Remove `dart:io` dependency from package `lib`, and move `commands` to `bin`.
|
|
- Replace `loadProgramInfo` util method with `loadProgramInfoFromJson`, which
|
|
expects an `Object` parameter instead of a `File` parameter.
|
|
- `buildComparisonTreemap` now expects two `Object` parameters for `oldJson` and
|
|
`newJson` instead of two `File` parameters.
|
|
- `compare` command now prints difference breakdown by node type when this
|
|
information is available.
|
|
|
|
## 0.4.0
|
|
|
|
- Add `buildComparisonTreemap` for constructing treemap representing the diff
|
|
between two size profiles.
|
|
- Implemented support for extracting call graph information from the AOT
|
|
compiler trace (`--trace-precompiler-to` flag), see `precompiler_trace.dart`.
|
|
- New command `explain dynamic-calls` which estimates the impact of different
|
|
dynamic calls on the resulting AOT snapshot size using information from the
|
|
size dump (e.g. V8 snapshot profile) and AOT compiler trace.
|
|
- `summary` command can now use information from the AOT compiler trace to
|
|
group packages/libraries together with their dependencies to given more precise
|
|
estimate of how much a specific package/library brings into the snapshot.
|
|
|
|
## 0.3.0
|
|
|
|
- Extract treemap construction code into a separate library, to make it
|
|
reusable.
|
|
- Add ability to collapse leaf nodes in a treemap created from V8 snapshot
|
|
profile. This behavior is programmatically controlled by `TreemapFormat format`
|
|
parameter and from CLI via `--format` flag. The following options are available
|
|
- `collapsed` essentially renders `ProgramInfo` as a treemap, individual
|
|
snapshot nodes are ignored.
|
|
- `simplified` same as `collapsed`, but also folds size information from
|
|
nested functions into outermost function (e.g. top level function or a
|
|
method) producing easy to consume output.
|
|
- `data-and-code` collapses snapshot nodes based on whether they represent
|
|
data or executable code.
|
|
- `object-type` (default) collapses snapshot nodes based on their type only.
|
|
- When computing `ProgramInfo` from a V8 snapshot profile no longer create
|
|
`ProgramInfoNode` for `Code` nodes which are owned by a function - instead
|
|
directly attribute the `Code` node itself and all retained nodes into
|
|
`ProgramInfoNode` for the function itself. For stubs (including allocation
|
|
stubs) create an artificial `functionNode` instead of using `NodeType.other`.
|
|
The only remaining use of `NodeType.other` is for fields.
|
|
|
|
## 0.2.0
|
|
|
|
- Update CLI help message to avoid referring to a snapshot created by pub as the
|
|
name of the script.
|
|
- Fix owner computation code for V8 profiles: the size of a snapshot node
|
|
which corresponds to a `ProgramInfoNode` should be attributed to that
|
|
`ProgramInfoNode` and not to its parent. For example `Function` node corresponds
|
|
to `ProgramInfoNode` of type `functionNode`, previously the size of `Function`
|
|
node would be attributed to the parent of this `ProgramInfoNode`, but it
|
|
should be attributed to the node itself.
|
|
- Update `README.md` to include more information on how to pass flags to
|
|
Dart AOT compiler.
|
|
- Add `ProgramInfoNode.size` documentation to clarify the meaning of the member.
|
