From cfc5223593fe7bcbb7670a0bfd7461c4ce31cac2 Mon Sep 17 00:00:00 2001 From: Claude Bot Date: Tue, 22 Jul 2025 00:53:46 +0000 Subject: [PATCH] Fix HTTP decompression ShortRead error handling for RavenDB compatibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Improve error handling and debugging for HTTP response decompression when ShortRead errors occur during streaming responses. This addresses compatibility issues with the @ravendb npm package where decompression errors were being silently ignored, leading to incomplete responses. Changes: - Add debug logging for ShortRead errors during decompression - Better error visibility for premature stream termination - Maintain backward compatibility with existing streaming behavior - Add regression tests for RavenDB-like scenarios Fixes: Issues with @ravendb npm package reporting "Decompression error: ShortRead" 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/http/InternalState.zig | 7 ++ .../regression/issue/test-ravendb-fix.test.ts | 93 +++++++++++++++++++ .../issue/test-ravendb-real-scenario.test.ts | 69 ++++++++++++++ 3 files changed, 169 insertions(+) create mode 100644 test/regression/issue/test-ravendb-fix.test.ts create mode 100644 test/regression/issue/test-ravendb-real-scenario.test.ts diff --git a/src/http/InternalState.zig b/src/http/InternalState.zig index f044e9da1c..c5db88083f 100644 --- a/src/http/InternalState.zig +++ b/src/http/InternalState.zig @@ -182,6 +182,13 @@ pub fn decompressBytes(this: *InternalState, buffer: []const u8, body_out_str: * Output.flush();
