From d9759e8a7ba89d7005d86cf8c8e3e561d04e56a4 Mon Sep 17 00:00:00 2001 From: Tianjie Xu Date: Fri, 21 Jul 2017 21:06:52 +0000 Subject: Fix a case when brotli writer fails to write last few blocks of data receive_new_data may exit too early if the zip processor has sent all the raw data. As a result, the last few 'new' commands will fail even though the brotli decoder has more output in its buffer. Restruct the code so that 'NewThreadInfo' owns the decoder state solely; and receive_brotli_new_data is responsible for the decompression. Also reduce the test data size to 100 blocks to avoid the test timeout. Bug: 63802629 Test: recovery_component_test. on bullhead, apply full updates with and w/o brotli compressed entries, apply an incremental update.
