  • Revision #2967 Tue 2011-05-10 18:19:11 +0200
    • small enhancement of the create table options feature:
    • no unnecessary casting from void*, more type safety.
    • typos fixed.
  • Revision #2966 Tue 2011-05-10 18:18:25 +0200
    • Fix Windows embedded warnings
  • Revision #2965 Tue 2011-05-10 18:00:28 +0200

    • Automatic merge Mariadb 5.1->5.2.
      • Revision #2643.127.9 Mon 2011-05-09 15:06:16 +0200
        • Fix buildbot failure in rpl_stop_slave.test.
        • Problem was setting DEBUG_SYNC twice in a row too fast in the test case; this could cause the second setting to override the first before the code had time to react to the first, causing the signal to get lost.
        • Fixed by waiting for the code to receive the first signal before overwriting it in the test case.
  • Revision #2963 Mon 2011-05-09 15:14:04 +0300
    • Make event stop code even more robust.
    • (Test failed if we added my_sleep(200000) in event_queue::cond_wait() just before pthread_cond_wait(); Not likely scenario but better to get that fixed too)
  • Revision #2962 Mon 2011-05-09 14:38:49 +0300
    • mysqltest: Write command to be executed to the log BEFORE executing the command.

          • Revision #2643.128.1 Wed 2011-05-04 15:45:39 +0200
            • Avoid mtr warning on Windows during startup
            • The reason for mtr warning is that collect_mysqld_features() starts mysqld with --datadir=/tmp and this directory does not exist on Windows.
            • Fix : instead of passing --datadir=$opt_vardir/tmp in collect_mysqld_features() just use --datadir=. mysqld does not need a correct directory, just an existing one, as it is started with --help ---verbose --skip-grant-tables.

        • Fix error in "make dist" (sql/CMakeLists.txt is not delivered in source distribution)
  • Revision #2947 Wed 2011-03-30 21:26:31 +0200
    • Bug #686006 : maria recovery tests fail.
    • All failing cases were attempts to use connection after the server was brought down and restarted. Connections used client reconnect option.
    • The reason for failures is the behavior of sockets on Windows: for a short period after crash (short enough to make the error not reproducible under debugger), write to socket on client side would succeed but subsequent read would fail.
    • MYSQL_OPT_RECONNECT does not really help in this case , because in the case given here ,as mysql_real_query() (which can handle reconnect option) succeeds and mysql_read_results() (can't handle reconnect) fails.
    • The fix is adding --include wait_until_connected_again.inc to appropriate places in test. This ensures that read errors are caught and connection is recreated.
  • Revision #2946 Wed 2011-03-30 19:20:22 +0300
    • Fixed problem that fill_record() allocated memory for every call. This could be a problem when doing big unions as memory could be filled up.
  • Revision #2945 Tue 2011-03-29 19:15:44 +0200
    • fix VS warning about variable 'unused' being used
  • Revision #2944 Tue 2011-03-29 19:01:42 +0200
    • Add optional CMake parameter TINY_VERSION.
    • Parameter setting has the effect on 4th part of the version string in executable's version info on Windows.
    • It could be set e.g to bzr revno to uniquely identify different builds for the same major.minor.patch combo.
  • Revision #2943 Mon 2011-03-28 16:53:46 +0200
    • Bug #702084 - myisam_block_size is not reported in SHOW GLOBAL VARIABLES
    • add a read-only server variable @@myisam_block_size

    • merge
      • Revision #2941.1.1 Mon 2011-03-28 17:01:40 +0200
        • CMake/code signing:
        • Use MYSQL_INSTALL_TARGETS() macro for DLLs (libmysql and libmysqld) to ensure that libraries are signed, if signing is requested.
  • Revision #2941 Mon 2011-03-28 12:56:34 +0200
    • Sign MSI if code signing is requested.
    • Remove SIGNCODE_ENABLED variable from create_msi.cmake.in, it was already removed from other places.
  • Revision #2940 Mon 2011-03-28 12:49:20 +0300
    • Fixed test failures with embedded server
  • Revision #2939 Mon 2011-03-28 02:02:24 +0200
    • Fix build error (wrong printf-like format)
  • Revision #2938 Mon 2011-03-28 01:05:34 +0200
    • CMake fixes for buildbot/MSI package building and signing:
      • FIND_PROGRAM (signtool) will now get a hint about location of signtool.exe (Windows SDK)
      • Targets "package" or "msi" will now fail, l if signing is requested but does not work (e.g invalid certificate)
      • During install, do not re-sign binaries, if they are already signed.
      • Preserve mysqld_error.h timestamp whenever possible. This helps avoiding situations where the whole server is rebuilt, whenever comp_err.exe changes (for example after code signing, or also after a minor fix in mysys)
      • Fix Wix error in UpgradeVersion, if patch part of the version is 0.
  • Revision #2937 [merge] Wed 2011-03-23 19:22:38 +0200
    • Merge with base 5.2
      • Revision #2933.1.2 Wed 2011-03-23 17:59:41 +0200
        • Added --log-basename to mysqld to allow one to set the prefix for all logs with one command
        • Changed test suite to use --log-basename (to get the code tested)
        • Added --sync-sys=1 to test suite to speed it up.
        • Better error messages if something goes wrong with mysql_install_db
      • Revision #2933.1.1 Fri 2011-03-18 17:03:43 +0200

        • The mysqld server and all clients now reads the new client-server section
        • Fixed that mysqldumpslow supports new slow log formats and new mysqld --slow- options

        • Address Monty's review comments
      • Revision #2919.1.26 Tue 2011-02-15 13:04:55 +0100
        • MWL#55 : Philip's review:
          • Take into account that mysql services start even with invalid defaults files (using data file relative to mysqld.exe location). Handle this case in upgrade scenarios, as if there was no --defaults-file in service definition.
      • Revision #2919.1.25 Mon 2011-02-14 19:36:06 +0100
        • MWL#55 : address Philip's final review comments :
          • rename upgrade_wizard.exe to mysql_upgrade_wizard.exe
          • have shortcut to upgrade wizard in the menu folder
      • Revision #2919.1.24 Tue 2011-02-08 13:07:31 +0100
        • MWL#55: look for my.cnf in addition to my.ini trying to figure out defaults file for the service
      • Revision #2919.1.23 Tue 2011-02-08 12:05:16 +0100
        • MWL#55: mysql_upgrade_service.exe will now ensure that datadir is always written to my.ini file
      • Revision #2919.1.22 Mon 2011-02-07 17:12:35 +0100
        • MWL#55 : Adjust UI according to some user's expectations.
        • If upgradable instances are found, bring a new dialog to inform user about it. This gives user a chance to deselect "database instance" feature early, because experience shows nobody really looks at features and their in their description in "customize setup" dialog. This also tells user that existing instances can be upgraded.
      • Revision #2919.1.21 Fri 2011-02-04 19:51:23 +0100
        • Remove --loose-skip-pbxt kludge from mysql_install_db and mysql_upgrade_service, after Bug #688404 was fixed.
      • Revision #2919.1.20 Fri 2011-02-04 19:47:56 +0100
        • Bug #688404 : Fix pbxt crashes on Windows 64 in debug build
        • The reason for the crash is misalignment on SSE instruciton in setjmp(). The root cause is PBXT debug malloc(), which unlike OS malloc does not guarantee 16 bytes alignment.
        • So the fix for now is disable PBXT debug malloc on Windows. It was obsolete anyway, as it does not provide additional benefits to C runtime debug routines (always used in debug compilation) or to pageheap, available at runtime.
      • Revision #2919.1.19 Fri 2011-02-04 12:20:41 +0100
        • MWL#55: Handle cases where service was installed with mysqld --install without any parameters.
        • In such case, service name is always MYSQL, as service binary path is "path\to\mysqld.exe" "MySQL". Guess data directory it is either from my.ini (which is assumed to be in the installation root), or just data directory under install root.
      • Revision #2919.1.18 Fri 2011-02-04 12:16:23 +0100
        • MWL#55 :
          • Allow MSI and NSIS side-by-side installation if installed NSIS package differs in "major.minor" version numbers. Still disallow MSI and NSIS if major.minor versions of both packages match.
      • Revision #2919.1.17 Thu 2011-02-03 21:02:20 +0100
        • On Philips request, introduce a variable BUILD_RELEASE to disable graceful fallbacks if WiX or MFC is not available.
      • Revision #2919.1.16 Thu 2011-02-03 18:56:30 +0100
        • MWL#55 : Add banner text to command line utilities (Philip's review)
      • Revision #2919.1.15 Thu 2011-02-03 17:51:03 +0100
        • MWL#55: correct mysqld.exe file path, to extract version from it.
        • Take into account that services registered by MySQL do not have .exe extension in service binary path.
      • Revision #2919.1.14 Thu 2011-02-03 16:05:21 +0100
        • MWL#55 : force per-machine installation.
        • Problem: user without privileges can have an half-complete installation, if he manages to click on "Ignore" for all errors in the installer.
        • As a result, he will miss ARP registry keys, and uninstall will not be possible using "Add/Remove Programs" applet.
      • Revision #2919.1.13 Wed 2011-02-02 01:34:22 +0100
        • AssignProcessToJobObject cannot assign current process on Win7 with the most strict user account control setting (secure desktop)
        • Fix: use job object for child process only, not for current process itself.
      • Revision #2919.1.12 Wed 2011-02-02 01:30:24 +0100
        • Fix service user name and directory ACL setting on localized Windows
          • Spell username correctly as "NT AUTHORITY\NetworkService"
          • Also, use well-known SIDs for predefined user when assigning directory ACLs (the names differ in localized Windows)
      • Revision #2919.1.11 Tue 2011-02-01 01:58:37 +0100
      • Revision #2919.1.10 Tue 2011-02-01 01:57:23 +0100

      • Revision #2919.1.5 Sat 2011-01-29 19:06:50 +0100
        • MWL#55 : implement MSI installer
        • The general technique to generate MSI using CMake is taken from MySQL 5.5
        • Additional features not present in 5.5 installer :
          • optionally creating a new database (as Windows service), using new mysql_install_db.exe to do the job
          • optional upgrade of existing services from old MySQL or Maria installation. This work is actually done by the upgrade wizard that is launched at the end of installation.
      • Revision #2919.1.4 Sat 2011-01-29 19:02:43 +0100
        • MWL#55 : implement upgrade_wizard - GUI program to uzpgrade existing MySQL/Maria services to higher version.
