The crash is caused by macro uint3korr() accessing memory (1 byte) past
the end of allocated page. The macro is written such it reads 4 bytes
instead of 3 and discards the value of the last byte.

However, it is not always guaranteed that all uint3korr accesses will be
valid (i.e that the caller allocates an extra byte after the value).

In particular, the tree in Item_func_group_concat does not account for
any extra bytes that it would need for comparison of keys in some cases
(Field_newdate::cmp, Field_medium::cmp)

The fix change uint3korr so it does not access extra bytes.

This reverts commit 1daf746e.

Removed temporarily to make sure there are no legal problems.

The man page was already present in the debian release of MariaDB 10.0.

Make use of a different function to get the current tid.

Additionally, librt doesn't exist on OS X. Use System library instead.

- don't use stat() for file size, it doesn not handle large size
  use GetFileSizeEx() instead

- don't use lseek(), it can't handle large files, use _lseeki64() instead.

- Also, switch off OS file buffering for innochecksum on Windows,
to avoid thrashing file cache.

Clang/LLVM has more strict schemantics than gcc.

This patch quantifies the namesspace such that it will
compile using clang.

Prior to this patch name of the user was  read from environment variable
USER, with a fallback to 'ODBC', if the environment variable is not set.

The name of the env.variable is incorrect (USERNAME usually contains current
user's name,  but not USER), which made client to  always determine
current user as 'ODBC'.

The fix is to use GetUserName() instead.

Fixes CMake so that when building a 32-bit mips binary on a 64-bit
mips machine, the target is not set as 32-bit, which apparently
confused some tests in mroonga.

The patch fixes 128-bit multiply on mips64.

This corrects a previous incorrect patch upstreamed from Debian.

Re-opening a TABLE object (after e.g. FLUSH TABLES or open table cache
eviction) causes ha_innobase to call
dict_stats_update(DICT_STATS_FETCH_ONLY_IF_NOT_IN_MEMORY).

Inside this call, the following is done:
  dict_stats_empty_table(table);
  dict_stats_copy(table, t);

On the other hand, commands like UPDATE make this call to get the "rows in
table" statistics in table->stats.records:

  ha_innobase->info(HA_STATUS_VARIABLE|HA_STATUS_NO_LOCK)

note the HA_STATUS_NO_LOCK parameter. It means, no locks are taken by
::info() If the ::info() call happens between dict_stats_empty_table
and dict_stats_copy calls, the UPDATE's optimizer will get an estimate
of table->stats.records=1, which causes it to pick a full table scan,
which in turn will take a lot of row locks and cause other bad
consequences.

Also add fallback version string for unknown future versions.

when opening a system table for a SELECT-like read, pretend
(for the sake of engines) it's SQLCOM_SELECT

There was race condition between online ALTER TABLE and statements performing
TABLE_SHARE release without marking it flushed (e.g. in case of table cache
overflow, SET @@global.table_open_cache, manager thread purging table cache).

The reason was missing mysql_cond_broadcast().

Linking tokudb with jemalloc privately causes problems on library
load/unload. To prevent dangling destructor pointers, link with the same
library as the server is using.
