pattern analysis: Use contiguous indices for enum variants
The main blocker to using the in-tree version of the `pattern_analysis` crate is that rustc requires enum indices to be contiguous because it uses `IndexVec`/`BitSet` for performance. Currently we swap these out for `FxHashMap`/`FxHashSet` when the `rustc` feature is off, but we can't do that if we use the in-tree crate.
This PR solves the problem by using contiguous indices on the r-a side too.
Fix crate IDs when multiple workspaces are loaded
Previously, we assumed that the crate numbers in a `rust-project.json` always matched the `CrateId` values in the crate graph. This isn't true when there are multiple workspaces, because the crate graphs are merged and the `CrateId` values in the merged graph are different.
This broke flycheck (see first commit), because we were unable to find the workspace when a file changed, so we every single flycheck, producing duplicate compilation errors.
Instead, use the crate root module path to look up the relevant flycheck. This makes `ProjectWorkspace::Json` consistenet with `ProjectWorkspace::Cargo`.
Also, define a separate JSON crate number type, to prevent bugs like this happening again.
feat: Add `rust-analyzer.cargo.allTargets` to configure passing `--all-targets` to cargo invocations
Closes#16859
## Unresolved question:
Should this be a setting for build scripts only ? All the other `--all-targets` I found where already covered by `checkOnSave.allTargets`
Fix tasks in tasks.json
#16839 refactored the representation of tasks inside the VS Code extension. However, this data type is exposed to users, who can define their own tasks in the same format in `tasks.json` or `.code-workspace`.
Revert the data type to have a `command` field rather than a `program` field, and document the different fields. This code is also a little complex, so split out a `cargoToExecution` to handle the Task to Execution conversion logic.
After this change, any tasks.json with a `command` field works again. For example, the following tasks.json works as expected:
```
{
"version": "2.0.0",
"tasks": [
{
"type": "cargo",
"command": "build",
"problemMatcher": [
"$rustc"
],
"group": "build",
"label": "my example cargo build task"
}
]
}
```

update: add editor/extension information to bug report template
When attempting to reproduce issues, I encounter difficulties due to differences in versions of LSP clients and editors (such as #16985, #16867, and more)
This sometimes consumes a lot of efforts from contributors to communicate the details about LSP client information. Therefore, I believe adding editor/extension information to the issue template would be helpful for problem reproduction.
fix: use lldb when debugging with C++ extension on MacOS
See https://github.com/rust-lang/rust-analyzer/issues/16901#issuecomment-2024486941
This PR resolves the issue of being unable to debug using the C++ extension on macOS. By using special configurations for the `MIMode` on macOS, it enables the C++ extension to connect to lldb when debugging (without affecting other platforms).
fix: lifetime length are not added in count of params in highlight
I found these two instances easily but I wonder how many such instances are there.
Fixes#16958
Revert to the crates.io version of rustc_pattern_analysis
The API hasn't fully settled yet, and there's an extra wrinkle with `IdxContainer` which blocked the [subtree update](https://github.com/rust-lang/rust/pull/122981). Let's just keep using the crates.io version for a bit longer.
