- "--databases" is a space separated list of entries
database_name[.table_name]
- "--databases-file" is a name of file which contains entries
database_name[.table_name] one entry per line
- check_if_table_matches_filters has been modified to check whether
database is enabled first and then check the table
- databases and tables filters initialization has been refactored in
order to avoid code duplication
- innnobackupex's --databases option is mapped to one of these
options, depending on value.

Fix for bug 1243009 --debug and --valgrind options needed for XtraBackup's build-binary.sh

util/build-binary.sh:
  Added new options --debug, --relwithdebinfo and --valgrind. These will set and export the DEBUG, RELWITHDEBINFO and VALGRIND variables to 'yes' before calling build.sh if specified. Even though they are mutually exclusive, there is no explicit test for this case.

  Added testing for RELWITHDEBINFO and VALGRIND variables and set up build/make options necessary for each case.

test/run.sh and test/inc/common.sh:
  Added -v N option to run.sh to allow enabling of valgrind when using test suite. N specifies a value that will be bassed to valgrinds --error-exitcode option. Made changes to accomplish this based on Alexey Kopytovs suggestions.
  Moved innobackupex_no_defaults_file into inc/common.sh from t/ib_doublewrite.sh since the concept is used in a few tests and correct fixup of IB_ARGS[@] is necessary in order to preserve args and valgrind options and makes a couple test cases a little simpler.

Bug #1227240 fix.

my.cnf can contain innodb_log_arch_dir option for server. xtrabackup can
use servers my.cnf. As innodb_log_arch_dir option can be used only for backup
preparing xtrabackup exits with error message in the case of backup with
innodb_log_arch_dir option. Such behavior does not allow to make backup if
default my.cnf contains innodb_log_arch_dir.

This fix ignores --innodb_log_arch_dir and --to-archived-lsn and outputs warning

Added new environment variables to control build:
  MAKE_ONLY - Set this to 1 to only re 'make' the server and xtrabackup. Nothing will be downloaded, unpacked or patched. This is not advised if any compiler or other flags are being changed from previous builds.
  RELWITHDEBINFO - Set this to 1 to eliminate optimizations by changing C/CXXFLAGS to -g -O0 and pass CMAKE_BUILD_TYPE=RelWithDebInfo to PS or MySQL 5.5+ cmake.
  WITH_VALGRIND - Set this to 1 to perform Valgrind compatible build. Eliminates optimizations just like RELWITHDEBINFO and also passes WITH_VALGRIND=ON to PS or MySQL 5.5+ cmake.
Added innobackupex option --use-valgrind which will prefix backup and apply-log calls to xtrabackup with "valgrind".

Various test suite cleanups:

* Re-implemented testrun.c in testrun.sh. This allows cleaner and more
  efficient implementations of parallel tests execution and status
  aggregation. Unlike previously, a server instance to detect version
  is now started just once before tests execution, which should save a
  lot of time. And we don't need to hash the binary. Progress is now
  reported and stats are also collected in the main script. And we
  also don't need multuple subunit files.

* As we don't need the run.sh wrapper now either, renamed testrun.sh
  back to its original name.

* Fixed bug #1097434 "CTRL-C or kill run.sh only terminates current
  test, not entire run" by defining appropriate signal handler in the script.

* Fixed bug #1097444 "xtrabackup test suite leaves xtrabackup.mysql.sock
  and xtrabackup_port_lock files behind in /tmp" by making sure
  everything is killed and cleaned up in all circumstances

* Fixed bug #1194813 "The port lock mechanism in XB test suite does not work"

* Time taken by each test is now reported

* The summary is now a lot more similar to MTR and includes test
  execution time stats and skipped tests summary.

* When a test fails in debug mode, information on where the artifacts
  can be found is now displayed in the summary

* record_db_state / verify_db_state now pass --skip-extended-insert to
  mysqldump, which makes identifying difference in data rows much
  easier.

* reduced the time we are waiting for a server to start by tweaking
  mysql_ping()

This implements the io-block-size option for XtraBackup and innobackupex (just for passthrough) which specifies number of pages to read/write per cycle.
Changes made:
- Increased the default from 64 pages to 256 pages (4M).
- Changed the ds_buffer size when chained behind compression to (UNIV_PAGE_SIZE * (xtrabackup_iosize + 1)), the one extra page is for any additional formatting overhead that would normally be seen in compression and xbstream.
- Corrected the retry logic in fil_cur.cc so that an individual page will be re-read up to a pre-determined number of times and for each validation failure, only that page will be re-read. Previous logic would re-read the entire block and continue counting retry failures even across failed, then successfully read pages.
- Created very simple test case that sets io-block-size to a larger value.
- Corrupt page reads are tested as part of bug766033.sh which creates a corrupted dataset and looks for the error message.
- Not tested as part of any test is a page that has been read and failed validation, then re-read and passed.

Blueprint: Support InnoDB buffer pool dumps in MySQL 5.6
https://blueprints.launchpad.net/percona-xtrabackup/+spec/support-56-buffer-pool-dumps
MySQL 5.6 adds an ability to dump the buffer pool into file for it to be
possible to load it into memory at startup or on demand. The location of
buffer pool file is set by global variable innodb_buffer_pool_filename
and is relative to MySQL data directory.
The patch adds an ability to take a backup of buffer pool dump. It has been
made exactly the same way as XtraDB LRU dump is backed up.
Three tests have been added for this feature. One takes regular backup and
after takes streaming backup. Another one takes backup with --rsync
option. Third test tests feature with incremental backups.

Revision Date: 2013-02-20 22:57:02 UTC

Introducing xtrabackup with encryption.

Encryption will be done through the libgcrypt library which can be found documented here: http://www.gnupg.org/documentation/manuals/gcrypt

Addition of libgcrypt requires now that libgcrypt and libgpgerror packages be installed.

Many package repositories still contain older versions of libgcrypt. The current stable version of 1.5.0 is reccomended and will take advantage of the AES-NI instruction set if available.

Similar to compression, encryption is not supported on streamed tar backups.

New options:
  --encrypt=<algorithm> : algorithm may be 'NONE', 'AES128', 'AES192' or 'AES256'. 'NONE' is used mainly for testing and is simply pass-through. Please refer to the libgcrypt manual for more information on these ciphers.

  --encrypt_key=<key> : a proper length encryption key to use. It is not reccomended to use this option where there is uncontrolled access to the machine as the command line and thus the key can be viewed as part of the process info. See option --encrypt_key_file.

  --encrypt_key_file=<keyfile> : the name of a file where the raw key of the appropriate length can be read from. The file must be a simple binary (or text) file that contains exactly the key to be used.

  --encrypt_threads=<threadcount> : number of threads used to encrypt in parallel (default=1).

  --encrypt_chunk_size=<size> : size (in bytes) of the working encryption buffer size for each encryption thread (default=64K).

  --compress_chunk_size=<size> : size (in bytes) of the working compression buffer size for each encryption thread (default=64K).

encrypt_key and encrypt_key_file are mutually exclusive. If --encrypt is specified, one of these MUST be specified else an error will occur.

encryption key lengths must be precise:
AES128=128 bits or 16 bytes
AES192=192 bits or 24 bytes
AES256=256 bits or 32 bytes

When using the encrypt_key_file option, the file specified may have binary or textual content but must be _exactly_ the correct size for the algorithm being used. If using text, caution must be taken so that there are no extra spaces, tabs, carriage returns or line feeds within the file. These will cause the key to be read as an incorrect size and an error will be generated.

The coding task was fairly straight forward with some restructure/refactoring approved by Alexey K:
  - Update/set copyright notice in new and touched files to Copyright (c) 2009-2013 Percona Ireland Ltd.
  - Implemented new ds_stdout data sink.
  - Split the ds_stream data sink into two new, more specific data sinks, ds_archive and ds_xbstream.
  - Implement write callback model for ds_xbstream similar to libarchive.
  - Change ds_archive and ds_xbstream over to using callback write models.
  - Add new option to compression --compress_chunk_size to allow user specified chunk size management.
  - Implement xbcrypt format reader/writer. Format encapsulated as follows:
      8 bytes - magic string "XBCRYP01"
      8 bytes - reserved
      8 bytes - original size
      8 bytes - encrypted size

  - Implement a new ds_encrypt datasync modeled after the existing compression datasync which will use libgcrypt for actual encryption task and write callbacks.
  - Add new options, options validations and pass through innobackupex.
  - Implement new utility xbcrypt modeled after xbstream to perform encryption outside of xtrabackup for metadata and to offer a means of decrypting an encrypted backup.
  - Implement new tests and refactor test script structure a little to make adding new, similar test cases a little easier.

Merge change to percona-xtrabackup-test from 2.0

Author: Ignacio Nin
Revision Date: 2012-11-21 17:44:29 UTC

Make the percona-xtrabackup-test packages archictecture independent.

Since the percona-xtrabackup-test packages are only scripts, text, and
other architecture-independent files, create a noarch/all package instead
of having one per platform.

add some basic tests of xtrabackup alongside some commonly used innodb server options. Also do some basic incremental tests with some server options. This is a starting point for further, more exhaustive testing of XB and server options combinations
