From 962e4538dadb29ddb45ef23254d70054bb8b67ab Mon Sep 17 00:00:00 2001 From: kshitijk4poor <82637225+kshitijk4poor@users.noreply.github.com> Date: Mon, 27 Jul 2026 23:18:45 +0500 Subject: [PATCH] refactor: reuse existing utilities in salvaged PR #72424 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three code-reuse fixes applied during salvage: 1. Reuse _relative_time from hermes_cli/main.py instead of duplicating the relative-time formatting logic in hermes_cli/status.py. 2. Extract _stamp_hygiene_compression_provenance helper in gateway/run.py to deduplicate the two nearly-identical try/except blocks that stamp compression timeout/abort provenance in the hygiene path. 3. Add ContextCompressor.record_timeout_failure() method and use it from the in-agent compress_context timeout callback instead of re-implementing the (60, 300, 900) cooldown ladder inline. The existing summary-LLM exception handler already has this ladder — now both paths share one method. --- agent/context_compressor.py | 18 +++++ gateway/run.py | 67 +++++++++---------- hermes_cli/status.py | 18 +---- run_agent.py | 13 +--- .../test_compress_context_progress_timeout.py | 8 +++ 5 files changed, 63 insertions(+), 61 deletions(-) diff --git a/agent/context_compressor.py b/agent/context_compressor.py index 9e93ac23d4..d3e04b0b20 100644 --- a/agent/context_compressor.py +++ b/agent/context_compressor.py @@ -1932,6 +1932,24 @@ class ContextCompressor(ContextEngine): self._cooldown_persist_failed = True logger.debug("compression failure cooldown persist failed (non-sqlite): %s", exc) + def record_timeout_failure(self, error: str) -> None: + """Record a consecutive timeout failure using the shared cooldown ladder. + + Used by both the summary-LLM exception handler (inline at line ~3714) + and the host-level ``compress_context`` timeout wrapper in + ``run_compress_context_with_progress_timeout``.
