If these are regular comments, then they won't appear in our d.ts files.
But, now we are relying on an external d.ts bundler to produce our final
merged, so they need to be present in the "input" d.ts files, meaning
they have to be JSDoc comments.
These comments only work today because all of our builds load their TS
files from scratch, so they see the actual source files and their
non-JSDoc comments.
The comments also need to be attached to a declaration, not floating,
otherwise they won't be used by api-extractor, so move them if needed.
This step converts as many explicit accesses as possible in favor of direct imports from the modules in which things were declared. This restores the code (as much as possible) back to how it looked originally before the explicitify step, e.g. instead of "ts.Node" and "ts.Symbol", we have just "Node" and "Symbol".
This step converts each file into an exported module by hoisting the namespace bodies into the global scope and transferring internal markers down onto declarations as needed.
The namespaces are reconstructed as "barrel"-style modules, which are identical to the old namespace objects in structure. These reconstructed namespaces are then imported in the newly module-ified files, making existing expressions like "ts." valid.
* Add different tests for baselining before behavior
* Fix assert for first project output
* Add ability to pass declaration, declarationMap, emitDeclarationOnly, sourceMap and inlineSourceMap on commandline of --build
* Store these options in --out scenario
* Store buildInfo program for --out even if not composite
* Changes to make these commanline options work
* Do not include sourceMapUrl text in the sourceFile version
* Emit complete program in --out scenario as well since we need to determine uptodate ness
* Copy js or dts bundle from old build if emitting only js or dts files
* Dont emit dts if we want to emit only js files even though options suggest emitting d.ts files as well
* Adding comments and refactoring some of the code
* Store dts change file path in buildinfo
* With composite, do not write d.ts files if they changed
* Determine dts change based on outputs
* Instead of storing time in buildinfo store filename which was last updated to get modified time stamp from
* Get declaration time change lazily
* Rename per feedback
* Add test when declaration emit has errors and d.ts emit doesnt change which results in incorrect incremental behaviour
* Refactor
* Use declaration diagnostics in the d.ts signature for the file so it can be more accurate for detecting changes to file that could affect other files
Fixes#49527
* Renames and clarifications
* Simplify serialize declaration diagnostics for signature purpose
Do not serialize file name if error is in same file we are emitting. this should avoid having to do file path computation in most cases.
Locations are start and length instead of line and character.
Do not use any indents
* Fix baselines
* Use fixed time for vfs so baselining is consistent
* Baseline buildinfos
* Write new file text in baseline even if the file wasnt read on the shadow
* Remove unnecessary debugger statement
* Make sure that incremental correctness is checked with correct writeFile so we know buildInfo was written
Also baseline these so its easy to verify the changes
* More baselines for the tsbuildinfo
* If we are writing dts file and have used file text as version, we can update the signature when doing actual emit
* Make WriteFileCallback Api ready for future
* Assert that there is only single source file when emitting d.ts file
* Add test
* Renames
* More refactoring
* If we are updating dts of any of the file and it affects global scope, everything needs update in signature and dts emit
Fixes#42769
* Stacktrace optimization for getModified time in anticipation of using it more than fileExists wherever possible
* Baseline getModifiedTime, setModifiedTime, fileExits and directoryExits for experiment
* Remove unnecessary write file finger print code since its not used at all
* Use modified time instead of file existence check
* Remove unnecessary getModifiedTime
* No need to check for file existence before reading the d.ts file
* Do project reference errors before doing input/output file checks
* Dont call getModifiedTimes if dts change
* Passdown modified time if queried
* Use modified time passed through the file watching in tsbuild
* Handle force build as separate upto date status
* uptodate status worker to read buildinfo and use it to determine upto date ness
* No need to update output timestamps if buildinfo will determine uptodateness
* Store change file set instead of hasPendingChange to be able to reuse the information
* Add test that shows input file is not present
* No need to check input time stamp before buildinfo
* Keep buildinfos for lifetime of the solution builder and project
* Store modified time along with text of buildinfo
* Non composite projects dont need to track declaration change time
* Pass through buildInfo so we dont have to parse it back
* Save dts change time in buildinfo itself
* Store dts time for --out in the buildInfo
* Store hash of text in the bundle info so it can be verified before manipulating text for fast updates during prepend
This helps when text changes during incremental build toggling and we determine we can just manipulate text
* Since buildinfo is cached no need to maintain version check state
* Store output time stamps for non incremental builds
* Revert "Baseline getModifiedTime, setModifiedTime, fileExits and directoryExits for experiment"
This reverts commit 7e65cd3315.

* String completion relative import suggestions respect the mode of the import when choosing if they provide extensions
* Style feedback
* Change diagnostic case
* add shape updates to baselines
* avoid computing a full shape for indirectly invalidated files
using file version as shape is enough to keep build info valid
and it's much cheaper
* Make export-module and reference maps invertible
Right now, we're enumerating all the entries to find out which keys map
to a corresponding value. By maintaining a two-way map, we can convert
this linear search into a map lookup and skip allocation of many, many
iterator results.
* Fix lint error
* Add some explanatory comments
* Rename, drop type parameters, and add readonly variant
* Simplify member list
* Fold non-exporting behavior into custom map type
* Always issue cannot find name did-you-mean error
This PR issues "cannot find ${name}, did you mean ${name}" errors for
identifiers and propery access expressions in JS files *without*
`// @ts-check` and without `// @ts-nocheck`. This brings some benefits of
Typescript's binder to all Javascript users, even those who haven't
opted into Typescript checking.
```js
export var inModule = 1
inmodule.toFixed() // errors on exports
function f() {
var locals = 2
locale.toFixed() // errors on locals
}
var object = {
spaaace: 3
}
object.spaaaace // error on read
object.spaace = 2 // error on write
object.fresh = 12 // OK, no spelling correction to offer
```
To disable the errors, add `// @ts-nocheck` to the file. To get the
normal checkJs experience, add `// @ts-check`.
== Why This Works ==
In a word: precision. This change has low recall — it misses lots
of correct errors that would be nice to show — but it has high
precision: almost all the errors it shows are correct. And they come
with a suggested correction.
Here are the ingredients:
1. For unchecked JS files, the compiler suppresses all errors except
two did-you-mean name resolution errors.
2. Did-you-mean spelling correction is already tuned for high
precision/low recall, and doesn't show many bogus errors even in JS.
3. For identifiers, the error is suppressed for suggestions from global files.
These are often DOM feature detection, for example.
4. For property accesses, the error is suppressed for suggestions from
other files, for the same reason.
5. For property accesses, the error is suppressed for `this` property
accesses because the compiler doesn't understand JS constructor
functions well enough.
In particular, it doesn't understand any inheritance patterns.
== Work Remaining ==
1. Code cleanup.
2. Fix a couple of failures in existing tests.
3. Suppress errors on property access suggestions from large objects.
4. Combine (3) and (4) above to suppress errors on suggestions from other, global files.
5. A little more testing on random files to make sure that precision
is good there too.
6. Have people from the regular Code editor meeting test the code and
suggest ideas.
* all (most?) tests pass
* NOW they all pass
* add tonnes of semi-colons
* restore this.x check+add a test case
* make ts-ignore/no-check codefix work in unchecked js
* Issues errors only in the language service
* add a few more tests
* fix incorrect parentheses
* More cleanup in program.ts
* Improve readability of isExcludedJSError
* make diff in program.ts smaller via closure
* Switch unchecked JS did-you-mean to suggestion
Instead of selectively letting errors through.
* undo more missed changes
* disallow ignoring suggestions
* Issue different messages for plain JS than others
Straw text for the messages, I just changed the modals to avoid name
collisions.
* Make handleDtsMayChangeOf void-returning
Right now, it always returns false. This seems important, since
otherwise it would stop graph traversals prematurely. It took me a
while to figure that out though and I thought it might be clearer if it
were simply void-returning.
I've kept the behavior the same, except in
`forEachReferencingModulesOfExportOfAffectedFile`, where it seemed like
never enqueueing new references was a mistake.
* Make forEachFileAndExportsOfFile void-returning
As far as I can tell, it could only return `false`.
Eg. program can backup and restore state changing the state object and we want to release program on the correct one
This ensure program is released correctly when there are declaration emit errors during tsc --build
* Serialize compiler options that are needed from old state when creating new state
* Dont write affectsGlobalScope if not true
* Encode FileInfo for better serialization size
* Update src/compiler/builder.ts
Co-authored-by: TypeScript Bot <typescriptbot@microsoft.com>
* Extra tests in preparation for lazy signature making sure the original intent of test is maintained
* Whenver we cant use state delay signature calculation and use source file version as signature
* Incremental correctness checks
* Retain old behavior in compile on save by disabling use of file version as signature in when state is not reused
* Use ids as 1 based so we can specialize `0` to be some special meaning
* Baseline tsbuildinfo size in the readable baseline
* Baseline fileName and fileNames list as well in readable tsbuildinfo so that new additions are easy to recognize
* Baseline readable buildinfo
* Use file names as index in file name list
This is extension of the idea given by @sokra to optimize size of tsbuildinfo
* Deduplicate reference map lists and use file name index to sort them
Different implementation of #43079 based on idea suggested by @sokra
* Minimal json.stringify for the tsbuildinfo
Again implementaion of suggestion by @sokra
* Update src/testRunner/unittests/tsbuild/helpers.ts
