vakabunga	8b57dd987e	Revert SSE streaming for PDF import, use synchronous flow SSE streaming added unnecessary complexity and latency due to buffering issues across Node.js event loop, Nginx proxy, and Docker layers. Reverted to a simple synchronous request/response for PDF conversion. Kept extractLlmErrorMessage for user-friendly LLM errors, lazy-loaded pdf-parse, and extended Nginx timeout.	2026-03-14 20:12:27 +03:00

vakabunga	db4d5e4d00	fix: yield to event loop after each SSE write to flush socket The for-await loop over OpenAI stream chunks runs synchronously when data is buffered, causing res.write() calls to queue without flushing. Add setImmediate yield after each progress event so the event loop reaches its I/O phase and pushes data to the network immediately.	2026-03-14 19:59:22 +03:00

vakabunga	67fed57118	fix: disable gzip and pad SSE events to prevent proxy buffering Add gzip off to Nginx import location — the global gzip on was buffering text/event-stream responses.

vakabunga	aaf8cacf75	fix: eliminate SSE buffering through Nginx proxy Add 2 KB padding comment after headers to push past proxy buffer threshold, enable TCP_NODELAY on the socket, and remove erroneous chunked_transfer_encoding off from Nginx that caused full response buffering.	2026-03-14 17:30:52 +03:00
vakabunga	e28d0f46d0	fix: reopen result modal from progress bar, faster progress, handle LLM context error - Move import modal visibility into ImportContext so the Layout progress pill can reopen the result dialog after the modal was closed. - Raise LLM progress cap from 85% to 98% and drop the intermediate -import 88%- SSE event to eliminate the visual stall after LLM finishes. - Detect LLM context-length errors (n_keep >= n_ctx) and surface a clear message instead of generic -Временная ошибка конвертации-.	2026-03-14 17:05:55 +03:00

vakabunga	78c4730196	fix: adaptive LLM progress estimation and emit 85% on stream end Hardcoded EXPECTED_CHARS (15k) caused progress to stall at ~20-25% for short statements. Now expected size is derived from input text length. Also emit an explicit 85% event when the LLM stream finishes, and throttle SSE events to 300ms to reduce browser overhead.	2026-03-14 16:41:12 +03:00
