This is required for prepared statements and stored procedures. BitKeeper/etc/ignore: Added bkpull.log bkpull.log.2 bkpull.log.3 build.log sql/safe_to_cache_query.txt to the ignore list sql/item_create.cc: Moved safe_to_cache_query from thd to lex. sql/item_func.cc: Moved safe_to_cache_query from thd to lex. sql/sql_cache.cc: Moved safe_to_cache_query from thd to lex. Note: Query_cache::is_cacheable() has both a thd and lex argument. We assumed that it's the lex->safe_to_cache_query we should test. sql/sql_class.cc: Moved safe_to_cache_query from thd to lex. sql/sql_class.h: Moved safe_to_cache_query from thd to lex. sql/sql_lex.cc: Moved safe_to_cache_query from thd to lex. We set it to 1 initially. It's then set to 0 in cases where it's know not to be safe. (Before this change, it was set to 0 in thd, and then set to 1 before parsing.) sql/sql_lex.h: Moved safe_to_cache_query from thd to lex. sql/sql_parse.cc: Moved safe_to_cache_query from thd to lex. No point in setting it here now, it's set in lex_start() later. sql/sql_prepare.cc: Moved safe_to_cache_query from thd to lex. Must set it after lex_start() has been called. sql/sql_yacc.yy: Moved safe_to_cache_query from thd to lex.
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'.
