* pgsql: Add tests for low-level PGLZ [de]compression routines @ 2026-04-14 20:12 Michael Paquier <michael@paquier.xyz> 0 siblings, 0 replies; 6+ messages in thread From: Michael Paquier @ 2026-04-14 20:12 UTC (permalink / raw) To: pgsql-committers@lists.postgresql.org Add tests for low-level PGLZ [de]compression routines The goal of this module is to provide an entry point for the coverage of the low-level compression and decompression PGLZ routines. The new test is moved to a new parallel group, with all the existing compression-related tests added to it. This includes tests for the cases detected by fuzzing that emulate corrupted compressed data, as fixed by 2b5ba2a0a141: - Set control bit with read of a match tag, where no data follows. - Set control bit with read of a match tag, where 1 byte follows. - Set control bit with match tag where length nibble is 3 bytes (extended case). While on it, some tests are added for compress/decompress roundtrips, and for check_complete=false/true. Like 2b5ba2a0a141, backpatch to all the stable branches.
