"SHOW TABLE STATUS very slow w/large number of tables" Replaced old algorithm which were used in my_dir() and stored all information about directory entries in one chunk of memory with new one which stores file names and MY_STAT structures in separate memroot, so now we don't need to copy this data during reallocation of dir_entry array. include/my_dir.h: Changed mystat member of FILEINFO structure to pointer since this prevents unneeded memory allocation and initialization. Added comment about new hidden members of MY_DIR structure. mysys/my_lib.c: Replaced old algorithm in my_dir() which stored all information about directory entries in one chunk of memory with new one which stores file names and MY_STAT structures in separate memroot. Now we don't copy this data during reallocation of array with FILEINFO structures. Also tuned sizes of memory chunks during first-other reallocations (we suppose that we either have < 100 files in the directory or > 1000 of them). sql/sql_show.cc: Updated only place in code where mystat member of FILEINFO structure is used. |

README |
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'.
