                 ChangeLog file for zlib
-Changes in port for MySQL (19 July 2004)
-- removed contrib, nt, os2, amiga, directories and some other files not used
-in MySQL distribution. If you are working on porting MySQL to one of rare
-platforms, you might find worth looking at the original zlib distribution 
-and using appropriate Makefiles/project files from it.

+36. Valgrind (or some similar memory access checker) says that deflate is
+    performing a conditional jump that depends on an uninitialized value.
+    Isn't that a bug?
+
+    No.  That is intentional for performance reasons, and the output of

+    zlib 1.2.x uses malloc() by default for allocations, whereas earlier
+    versions used calloc(), which zeros out the allocated memory.

+38. How can I encrypt/decrypt zip files with zlib?
 
     zlib doesn't support encryption. The original PKZIP encryption is very weak
     and can be broken with freely available programs. To get strong encryption,
     use GnuPG, http://www.gnupg.org/ , which already includes zlib compression.

     No. PKWare has apparently decided to keep that format proprietary, since
     they have not documented it as they have previous compression formats.
     In any case, the compression improvements are so modest compared to other
     more modern approaches, that it's not worth the effort to implement.

Subject: [PATCH 02/14] Fix for BUG#12882 - min/max inconsistent on empty
 table.

The problem was in that the MIN/MAX optimization in opt_sum_query was
replacing MIN/MAX functions with their constant argument without
taking into account that a query has no result rows.

Subject: [PATCH 05/14] Fix bug #13180 thd->allow_sum_funcs wasn't reset before
 query processing.

thd->allow_sum_func was left 'true' after previous statement thus allowing
sum funcs to be present in conditions.

thd->allow_sum_func should be set to 0 for each query and each prepared
statement reinitialization. This is done in lex_start() and
reset_stmt_for_execute().
