fix: what the third round broke, and the first batch's review
MCP preview after the server lost a session (it expired, or the MCP process restarted): - Every server state has an id, made when the state is created. The tab notices a new id even when the version numbers happen to match, and every push names the state it was based on, so one based on a lost state is refused, also when it comes before the tab's first poll (the server recovers the saved file first). - The tab keeps the newest canvas XML, saved or not. When the server knows nothing (no file) or exactly what the tab last saved, the canvas wins and is saved, so edits made while the server was down are kept. Otherwise the server's diagram (an AI write the tab missed, a cleared document that was saved) is shown and the tab's copy goes to History. - Late answers to an old state's push or poll are dropped; a failed push says the server is unreachable; Download as .drawio saves the canvas. Settings and server: - Saved providers this version does not know stay in storage with their keys, and sending no longer trips over them. - The desktop "Ollama (Local)" preset with a key goes to local Ollama again; a server model's Ollama URL variable is read; the admin panel writes Ollama Cloud's URL for a key without one. - Provider error texts show again in the desktop app and for EdgeOne. - .env: a quoted value followed by a comment ending in a quote is read as dotenv reads it; unquoted values are unchanged. - Desktop app: the next launch opens the port where a chat was last saved; a launch elsewhere that saves nothing does not move it, and a page with no chats lets the next launch try the other port once. - The Test button no longer stays busy after another tab changed the key. - A completed append_diagram is no longer undone by an earlier failed edit's preview; a file read once in vain is saved again once it is read or gone. From the first batch's review: - The admin panel's Test of an entry without a URL now tests the server's <P>_BASE_URL, where chat sends the entry's key; chat is unchanged (the first fix rerouted working setups). - The model list ends downloads that are too large, accepts answers without a body, and keeps the "redirects are not allowed" explanation. - A test covers the preview's History rendering. |

fix(chat): keep the canvas after an unrelated error, and more review fixes
Found by the second PR review: - After a streamed edit, an older render of the stream stored the edit's original diagram again, and the next failed request (no quota, a lost connection) put that old diagram back on the canvas. The tool handler now marks its call as handled, so the preview code leaves it alone. - An edit applied before the UI showed an earlier broken edit's error was erased when that error undid its preview, or was built on that preview. The handler now starts from the diagram before all unhandled previews, and reads the diagram state that updates at once. - A failed or stopped display_diagram left its half drawn diagram on the canvas. Its preview is undone now, like an edit's. - "New chat" cleared a chat that could not be saved (storage full). - The settings dialog showed a model list, a fetch error or a test result on the provider that was opened after the request started, and marked a model id changed during the test as tested. - A tool call with broken JSON was shown as cut off by the output limit. - History entries and session thumbnails could pair with a later diagram when draw.io answered an export late. - A server model saved before non-ASCII provider names got into the id was reset to the default model. |

fix(diagram): fix autosave staleness and XML repair corrupting valid diagrams
- Autosave guard reads refs, so edits after a theme or dark mode switch are kept - Duplicate-id check and rename run per page; repair loop no longer quadratic - autoFixXml no longer breaks style values, rich text " or single-line cells - extractCompleteMxCells keeps the cell after a self-closing cell - Better truncation detection; object/UserObject wrapped cells are editable - Exports for thumbnail, PNG and save are routed by tag instead of a shared resolver - History stores the full document; storage errors are reported, no auto-deletion of chats - IndexedDB connection reopens after errors; focus refresh throttled - Keep ?session= on locale redirect, map zh-Hant to zh-tw for draw.io |
