BUG#31277 - myisamchk --unpack corrupts a table With certain data sets (when compressed record length gets bigger than uncompressed) myisamchk --unpack may corrupt data file. Fixed that record length was wrongly restored from compressed table. myisam/mi_check.c: With compressed tables compressed record length may be bigger than pack_reclength, thus we may allocate insufficient memory for record buffer. Let single function allocate record buffer, performing needed record length calculations. Still, it is not doable with parallel repair, as it allocates needed record buffers at once. For parellel repair added better record length calculation. myisam/mi_open.c: When calculating record buffer size, take into account that compressed record length may be bigger than uncompressed. myisam/mi_packrec.c: With certain data set share->max_pack_length (compressed record length) may be bigger than share->base.pack_reclength (packed record length). set_if_bigger(pack_reclength, max_pack_length) in this case causes myisamchk --unpack to write extra garbage, whereas pack_reclength remains the same in new index file. As a result we get unreadable table. myisam/myisamchk.c: With compressed tables compressed record length may be bigger than pack_reclength, thus we may allocate insufficient memory for record buffer. Let single function allocate record buffer, performing needed record length calculations. mysql-test/mysql-test-run.pl: Environment variables to execute myisamchk and myisampack. mysql-test/r/myisampack.result: New BitKeeper file ``mysql-test/r/myisampack.result'' mysql-test/t/myisampack.test: New BitKeeper file ``mysql-test/t/myisampack.test''
