When a node restarts it starts over again with fetching the configuration - It is not sure that it can use the "old dynamically allocated port number" again. - It should however try to reuse the old one, if not possible it should allocate a new one. One has to be able to distinguish between portnumbers specified originally in the config, and ones that has been dynamically added (the latter may be changed if "busy", but the first cannot be changed). We use negative portnumbers for ports that are ok to change. ndb/include/mgmapi/mgmapi_debug.h: change prototype for: ndb_mgm_set_connection_int_parameter ndb_mgm_get_connection_int_parameter Accept/set an int instead of an unsigned ndb/include/transporter/TransporterRegistry.hpp: Use an int (signed) to represent a port number. Zero means dynamic (but unassigned) >0 means static (defined in configuration) <0 means dynamic (and should be converted to positive before use) ndb/src/common/mgmcommon/IPCConfig.cpp: Set up the Transporter with a port number of the correct sign. ndb/src/common/transporter/TransporterRegistry.cpp: start_clients_thread: - handle negative port numbers add_transporter_interface: - accept signed integer as port number start_service: - If port is dynamic (<0), try to bind to it. if that fails (e.g. some other process has taken that port), then get a new dynamic port number. ndb/src/mgmapi/mgmapi.cpp: Use a signed integer for value in: ndb_mgm_set_connection_int_parameter ndb_mgm_get_connection_int_parameter Cast to a Uint32 for storage/retrieval to/from Properties ndb/src/mgmsrv/MgmtSrvr.cpp: getConnectionDbParameter - return value as integer (signed) - cast as Uint32 for iter.get ndb/src/mgmsrv/MgmtSrvr.hpp: Update prototype of getConnectionDbParameter int value (not unsigned anymore) ndb/src/mgmsrv/Services.cpp: MgmApiSession::getConnectionParameter - value is now signed |

This is a release of MySQL, a GPL (free) SQL database server (more licence information in the PUBLIC file and in the reference manual). Please read the "Upgrading from..." section in the manual first, if you are migrating from older versions of MySQL! The latest information about MySQL can be found at: http://www.mysql.com To see what it can do take a look at the features section in the manual. For installation instructions see the Installation chapter in the manual. For future plans see the TODO appendix in the manual. New features/bug fixes history is in the news appendix in the manual. For the currently known bugs/misfeatures (known errors) see the bugs appendix in the manual. For examples of SQL and benchmarking information see the bench directory. The manual mentioned above can be found in the Docs directory. The manual is available in the following formats: as plain ASCII text in Docs/manual.txt, in HTML format in Docs/manual_toc.html, as GNU Info in Docs/mysql.info and as PostScript in Docs/manual.ps. MySQL is brought to you by the MySQL team at MySQL AB For a list of developers and other contributors, see the Credits appendix in the manual. ************************************************************ IMPORTANT: Send bug (error) reports, questions and comments to the mailing list at mysql@lists.mysql.com Please use the 'mysqlbug' script when posting bug reports or questions about MySQL. mysqlbug will gather some information about your system and start your editor with a form in which you can describe your problem. Bug reports might be silently ignored by the MySQL maintainers if there is not a good reason included in the report as to why mysqlbug has not been used. A report that says 'MySQL does not work for me. Why?' is not considered a valid bug report. The mysqlbug script can be found in the 'scripts' directory of the distribution, that is '<where-you-installed-mysql>/scripts'.
