This caused incorrect completion display when: - User typed while waiting for LLM response - Completion text didn't align with cursor position - Stale completions were shown The fix: 1. Recalculates prefix/suffix when LLM promise resolves 2. Properly calculates matchup bounds using getAutocompletionMatchup 3. Handles cases where prefix changed too much (returns empty completions) This matches the pattern used for cached autocompletions and ensures completions display correctly. --- .../cortexide/browser/autocompleteService.ts | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) diff --git a/src/vs/workbench/contrib/cortexide/browser/autocompleteService.ts b/src/vs/workbench/contrib/cortexide/browser/autocompleteService.ts index 28b0f788651..f70348ccefb 100644 --- a/src/vs/workbench/contrib/cortexide/browser/autocompleteService.ts +++ b/src/vs/workbench/contrib/cortexide/browser/autocompleteService.ts @@ -923,8 +923,21 @@ export class AutocompleteService extends Disposable implements IAutocompleteServ await newAutocompletion.llmPromise // console.log('id: ' + newAutocompletion.id) - const autocompletionMatchup: AutocompletionMatchupBounds = { startIdx: 0, startLine: 0, startCharacter: 0 } - const inlineCompletions = toInlineCompletions({ autocompletionMatchup, autocompletion: newAutocompletion, prefixAndSuffix, position }) + // Recalculate prefix and suffix in case user typed more while waiting for LLM response + const currentPrefixAndSuffix = getPrefixAndSuffixInfo(model, position) + const currentPrefix = currentPrefixAndSuffix.prefix + + // Calculate the matchup bounds - this determines where in the generated text to start showing the completion + const autocompletionMatchup = getAutocompletionMatchup({ prefix: currentPrefix, autocompletion: newAutocompletion }) + + // If matchup is undefined, the prefix has changed too much (user typed beyond the completion) + // In this case, return empty completions + if (!autocompletionMatchup) { + this._autocompletionsOfDocument[docUriStr].delete(newAutocompletion.id) + return [] + } + + const inlineCompletions = toInlineCompletions({ autocompletionMatchup, autocompletion: newAutocompletion, prefixAndSuffix: currentPrefixAndSuffix, position }) // Record performance metrics const providerTime = performance.now() - providerStartTime; From 241ecf473e8e32b9e58c1d3c8804c3ccb565b5ac Mon Sep 17 00:00:00 2001 From: Tajudeen Date: Wed, 7 Jan 2026 23:48:12 +0000 Subject: [PATCH 08/18] Fix FIM support for all providers - Removed FIM from providers that don't support suffix parameter: - OpenAI (official API doesn't support it) - xAI, DeepSeek, Groq (OpenAI-compatible but no suffix support) - vLLM (docs confirm no suffix support) - lmStudio (comment confirms no suffix support) - Kept FIM for providers that support it: - Mistral (native FIM endpoint) - Ollama (native FIM support) - OpenRouter, OpenAI-compatible, LiteLLM (may support depending on backend) - Updated filter logic to match actual implementations - Added clear comments explaining which providers support FIM and why --- .../cortexide/browser/autocompleteService.ts | 114 ++++++++++++++---- .../common/cortexideSettingsService.ts | 48 ++++++-- .../llmMessage/sendLLMMessage.impl.ts | 41 ++++--- 3 files changed, 156 insertions(+), 47 deletions(-) diff --git a/src/vs/workbench/contrib/cortexide/browser/autocompleteService.ts b/src/vs/workbench/contrib/cortexide/browser/autocompleteService.ts index f70348ccefb..207d9de02fc 100644 --- a/src/vs/workbench/contrib/cortexide/browser/autocompleteService.ts +++ b/src/vs/workbench/contrib/cortexide/browser/autocompleteService.ts @@ -24,6 +24,7 @@ import { IConvertToLLMMessageService } from './convertToLLMMessageService.js'; import { getPerformanceHarness } from '../common/performanceHarness.js'; import { isLocalProvider } from './convertToLLMMessageService.js'; import { IModelWarmupService } from '../common/modelWarmupService.js'; +import { INotificationService } from '../../../../platform/notification/common/notification.js'; @@ -113,13 +114,16 @@ class LRUCache { const value = this.items.get(key); if (value !== undefined) { - // Call dispose callback if it exists + // Remove from cache first, then call dispose callback + // This prevents the callback from seeing the item as still in cache + this.items.delete(key); + this.keyOrder = this.keyOrder.filter(k => k !== key); + + // Call dispose callback if it exists (after removal to avoid issues) if (this.disposeCallback) { this.disposeCallback(value, key); } - this.items.delete(key); - this.keyOrder = this.keyOrder.filter(k => k !== key); return true; } @@ -170,8 +174,8 @@ type Autocompletion = { _newlineCount: number; }; -const DEBOUNCE_TIME = 500; -const TIMEOUT_TIME = 60000; +const DEBOUNCE_TIME = 250; // Reduced from 500ms for better responsiveness +const TIMEOUT_TIME = 15000; // Reduced from 60s to 15s for autocomplete const MAX_CACHE_SIZE = 20; const MAX_PENDING_REQUESTS = 2; @@ -496,8 +500,7 @@ const getAutocompletionMatchup = ({ prefix, autocompletion }: { prefix: string; if (lineStart < 0) { // console.log('@undefined3') - - console.error('Error: No line found.'); + console.warn('[Autocomplete] Matchup calculation failed: No line found.
