# vscode-0001: extensionGalleryService.getExtensions uuid dedup O(N×M)
|
||
#
|
||
# File: src/vs/platform/extensionManagement/common/extensionGalleryService.ts
|
||
# Function: getExtensions (line ~659)
|
||
#
|
||
# Defect: uuids array built via result.map(), then for each extensionInfo
|
||
# uuids.includes(e.uuid) is called — O(N×M) where N=extensionInfos,
|
||
# M=result count.
|
||
# Fix: Convert uuids to a Set for O(1) lookup.
|
||
# Severity: MEDIUM (N=installed extensions, typically 50-200)
|
||
# Speedup: 100x at N=200
