Julius Goryavsky	17e0f5224c	MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.	4 years ago
