| * | mariabackup - rename backup-rocksdb option to rocksdb-backupVladislav Vaintroub2018-06-221-1/+1
| | | | | | | | | | | | | | | to avoid "using unique option prefix 'backup' is error-prone", there is already --backup option there.
| * | MDEV-16519 : mariabackup should fail if MDL could not be acquired with ↵Vladislav Vaintroub2018-06-221-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lock-ddl-per-table There is a tiny chance for race condition during MDL acquisition. If table is renamed just prior to SELECT 1 FROM <table_name> LIMIT 0 then this query would fail, yet mariabackup --backup does not handle it as fatal error and continues, only to fail later during file copy. The fix is to die on error, of MDL lock query fails.

| * | Follow-up to MDEV-16367 mariabackup: error: failed to copy enough redo logMarko Mäkelä2018-06-151-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit dc9c555415b1d37b713839b9f8143a053f402c0e moved the final phase of the redo log copying to the background thread. This would sometimes cause too little redo log to be copied at the end of the backup. We would only guarantee copying up to the latest redo log checkpoint. This would produce a consistent backup, but it could refer to a too old point of time. xtrabackup_copy_log(), xtrabackup_copy_logfile(): Add the parameter 'last'. xtrabackup_backup_low(): Copy any remaining part of the log after the backup threads have terminated.

| * | MDEV-16457 mariabackup 10.2+ should default to innodb_checksum_algorithm=crc32Marko Mäkelä2018-06-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since MariaDB Server 10.2.2 (and MySQL 5.7), the default value of innodb_checksum_algorithm is crc32 (CRC-32C), not the inefficient "innodb" checksum. Change Mariabackup to use the same default, so that checksum validation (when using the default algorithm on the server) will take less time during mariabackup --backup. Also, mariabackup --prepare should be a little faster, and the server should read backups faster, because the page checksums would only be validated against CRC-32C.

(Previously, we would stop copying as soon as the first batch of xtrabackup_copy_logfile() returned.) log_copying: Remove. Use log_copying_running instead. copy_logfile: Remove. Log copying will now only be invoked from 2 places: from xtrabackup_backup_func() for the initial batch, and from log_copying_thread() until all of the log has been read. Use the global variable metadata_to_lsn for determining if the final part of the log is being copied. xtrabackup_copy_log(): Add diagnostic messages for terminating the copying. These messages should be dead code, because log_group_read_log_seg() should be checking for the same. xtrabackup_copy_logfile(): Correct the retrying logic. If anything was successfully read, process the portion that was read. On failure, let the caller close dst_log_file. io_watching_thread(): Stop throttling during the last phase of copying the log (metadata_to_lsn!=0). The final copying of the log will now be performed in log_copying_thread(). stop_backup_threads(): Clean up the message about stopping the log copying thread. xtrabackup_backup_low(): Read metadata_to_lsn from the latest checkpoint header page, even if it is the first page. Let the log_copying_thread take care of copying all of the redo log.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make mariadb crc32 lib platform independent It looks strange that someone can make use of 2 crc libraries (Power64 or AArch64) at the same time. The patch sets macros 'CRC32_LIBRARY' to make platform independence as an optional crc32 library. Change-Id: I68bbf73cafb6a12f7fb105ad57d117b114a8c4af Signed-off-by: Yuqi Gu <yuqi.gu@arm.com>

| * | mariabackup : Fix race condition when killing query waiting for MDLVladislav Vaintroub2018-05-191-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Itcan happen that the connection is already gone during the window between quering I_S.PROCESSLIST and KILL QUERY. Fix is to tolerate ER_NO_SUCH_THREAD returned from KILL QUERY. Add small improvement in message "Killing MDL query " to actually output the query. Also do not try to kill queries that are already in Killed state.

* | | MDEV-12218: Put back mariabackup --innodb-flush-methodMarko Mäkelä2018-04-304-32/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement innodb_flush_method as an enum parameter in Mariabackup, instead of ignoring the option and hard-wiring it to a default value. xb0xb.h: Remove. Only xtrabackup.cc refers to the enum parameters. innodb_flush_method_names[], innodb_flush_method_typelib[]: Define as non-static, so that mariabackup can share the definitions. srv_file_flush_method: Change the type to ulong, to match the assignment in init_one_value() and handle_options() in mariabackup.

| | * MDEV-15779 - mariabackup incremental prepare fails on CIFS mount.Vladislav Vaintroub2018-04-121-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CIFS does not like O_DIRECT flag (it is set successfully, but pread would fail). The fix is not to use O_DIRECT, there is not need for it. posix_fadvise() was used already that should prevent buffer cache pollution on Linux. As recommended by documentation of posix_fadvise(), we'll also fsync() tablespaces after a batch of writes.
| | * MDEV-15780 : Mariabackup with absolute paths in innodb_data_file_pathVladislav Vaintroub2018-04-122-4/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | System tablespace can be specified with absolute path, if innodb_data_home_dir is empty. This was not handled well by mariabackup 1. In backup phase, empty innodb_data_home_dir variable from server was not recognized. full paths were stored in backup-my.ini, even if it stored all files locally. thus prepare phase would not find the system tablespace files. 2. In copy-back phase, copy would not be done to the absolute destination path, as path would be stripped with trim_dotslash This patch fixes the above defects.
