BUG#15787 - MySQL crashes when archive table exceeds 2GB
Max compressed file size was calculated incorretly causing server crash on INSERT. With this patch we use proper max file size provided by zlib. Affects 5.0 only. sql/ha_archive.cc: When calculating max compressed file size, use the real offset size that is provided by zlib, instead of sizeof(z_off_t), which may be different from actual offset size. When we're about to write and the data file is almost full flush gzio buffer to get accurate real file size. mysql-test/r/archive-big.result: New BitKeeper file ``mysql-test/r/archive-big.result'' mysql-test/t/archive-big.test: New BitKeeper file ``mysql-test/t/archive-big.test''
