From 511fc2a3450a5c09fe222771d8889ce6fa52b9fc Mon Sep 17 00:00:00 2001 From: Jake Bailey <5341706+jakebailey@users.noreply.github.com> Date: Mon, 28 Sep 2026 20:02:53 -0700 Subject: [PATCH 1/5] Keep inclusion diagnostics local to each program Cloned programs share inclusion records, but diagnostics derived from those records can refer to a particular program's files. Caching them on the shared records lets later generations reuse diagnostics from an old program and prolong the lifetime of its source files. Keep derived diagnostics with their program and make the shared payloads explicit so the reusable records cannot hide arbitrary owners. --- tsc/internal/compiler/fileInclude.go | 51 ++++++++----------- tsc/internal/compiler/fileloader.go | 46 ++++++++--------- tsc/internal/compiler/filesparser.go | 34 ++++++------- tsc/internal/compiler/includeprocessor.go | 27 +++++----- tsc/internal/compiler/processingDiagnostic.go | 18 ++++--- tsc/internal/compiler/program.go | 22 ++++---- tsc/internal/compiler/program_test.go | 38 +++++++++----- 7 files changed, 123 insertions(+), 113 deletions(-) diff --git a/tsc/internal/compiler/fileInclude.go b/tsc/internal/compiler/fileInclude.go index 1b23b73359ed2..e9a1f3b0bce07 100644 --- a/tsc/internal/compiler/fileInclude.go +++ b/tsc/internal/compiler/fileInclude.go @@ -2,7 +2,6 @@ package compiler import ( "fmt" -

Retain only host-free resolution data, and bind lazy queries to the current program host. Package lookups can populate caches after construction, so each program needs its own package-json cache table. Construction-only resolution caches do not need to survive in completed programs. --- tsc/internal/api/module_resolution.go | 18 +--- tsc/internal/compiler/emitHost.go | 5 - tsc/internal/compiler/fileloader.go | 10 +- tsc/internal/compiler/filesparser.go | 2 -
