The fix is to allow myisamchk to use >4G key_buffer_size on win64
|
|
|
|
|
|
|
| |
The problem was that new lock types were being added without a
corresponding description. Since the lock types (enum values)
are used as indices to the description array, the descriptions
could be shifted depending on the lock type. The solution is to
ensure that every lock type has a correspondent description.

- Header <sys/ttydefaults.h> missing or not usable on QNX and OpenServer 6
include/my_global.h
- Moved down definition of function rint(), as for some platforms (in
this case Netware) 'longlong' is not defined until later in
"my_global.h"

produce incorrect results for ROUND()
Added a workaround and a configure check to test whether
isinf() is affected by the GCC bug #39228.
Since no code in MySQL server is currently affected by that
bug, the patch is actually a safeguard for possible future
code modifications. No test cases or changelog entries are
needed.

- Remove bothersome warning messages. This change focuses on the warnings
that are covered by the ignore file: support-files/compiler_warnings.supp.
- Strings are guaranteed to be max uint in length

continue to update it at make-time.
One shouldn't need to run "make" on server source to get the stuff we say
plugins should use.

Replaced a call to load_defaults() in sql_plugin.cc with
its thread-safe version.

in load_defaults()
load_defaults(), my_search_option_files() and
my_print_default_files() utilized a global variable
containing a pointer to thread local memory. This could lead
to race conditions when those functions were called with high
concurrency.
Fixed by changing the interface of the said functions to avoid
the necessity for using a global variable.
Since we cannot change load_defaults() prototype for API
compatibility reasons, it was renamed my_load_defaults().
Now load_defaults() is a thread-unsafe wrapper around
a thread-safe version, my_load_defaults().

Took the Xfree implementation (based on the same rewrite as the NDB one)
and added it instead of the current implementation.
Added a macro to make the calls to MD5 more streamlined.

When disk is full, server may waiting for free space while
writing binlog, relay-log or MyISAM tables. The server will
continue after user have freed some space. But the error
message printed was not quite clear about the how often the
error message is printed, and there will be a delay before
the server continue and user freeing space. And caused users
thinking that the server was hanging forever.
This patch fixed the problem by making the error messages
printed more clear. The error message is split into two part,
the first part will only be printed once, and the second part
will be printed very 10 times.
Message first part:
Disk is full writing '<filename>' (Errcode: <errorno>). Waiting
for someone to free space... (Expect up to 60 secs delay for
server to continue after freeing disk space)
Message second part:
Retry in 60 secs, Message reprinted in 600 secs

Add all HA error numbers and descriptions to perror.
Add reminder to header.
This is already fixed in smarter ways in future codebases, and this
codebase is unlikely to change, since new development is forbidden
here.

for bug #15936.
On some platforms fenv.h may #undef the min/max macros
defined in my_global.h.
Fixed by moving the #include directive for fenv.h from
mysqld.cc to my_global.h before definitions for min/max.

Several functions (mostly in mysqld.cc) directly call
exit() function in case of errors, which is not a desired
behaviour expecially in the embedded-server library.
Fixed by making these functions return error sign instead
of exiting.

Both of our own implementations of rint(3) were inconsistent with the
most common behavior of rint() on those platforms that have it: round
to nearest, break ties by rounding to nearest even.
Fixed by leaving just one implementation of rint() in our source tree,
and changing its behavior to match the most common native
implementations on other platforms.

upgrading lock, even with low_priority_updates
The problem is that there is no mechanism to control whether a
delayed insert takes a high or low priority lock on a table.
The solution is to modify the delayed insert thread ("handler")
to take into account the global value of low_priority_updates
when taking table locks. The value of low_priority_updates is
retrieved when the insert delayed thread is created and will
remain the same for the duration of the thread.

code backported from 6.0
per-file messages:
include/my_global.h
Remove SC_MAXWIDTH. This is unused and irrelevant nowadays.
include/my_sys.h
Remove errbuf declaration and unused definitions.
mysys/my_error.c
Remove errbuf definition and move and adjust ERRMSGSIZE.
mysys/my_init.c
Declare buffer on the stack and use my_snprintf.
mysys/safemalloc.c
Use size explicitly. It's more than enough for the message at hand.
sql/sql_error.cc
Use size explicitly. It's more than enough for the message at hand.
sql/sql_parse.cc
Declare buffer on the stack. Use my_snprintf as it will result in
less stack space being used than by a system provided sprintf --
this allows us to put the buffer on the stack without causing much
trouble. Also, the use of errbuff here was not thread-safe as the
function can be entered concurrently from multiple threads.
sql/sql_table.cc
Use MYSQL_ERRMSG_SIZE. Extra space is not needed as my_snprintf will
nul terminate strings.
storage/myisam/ha_myisam.cc
Use MYSQL_ERRMSG_SIZE.
sql/share/errmsg.txt
Error message truncation in test "innodb" in embedded mode
filename in the error message can safely take up to 210 symbols.

For reasons that are now a mystery, we had defined a CPP symbol to
help ancient compilers work better (in some way that's lost to history).
This interferes with at least one modern compiler.
Now, don't define the _PC symbol. Those other underscore-leading
symbols are suspect also, but at least the names aren't inscrutable.
Let's leave them for now.

myisam_repair_threads > 1 causes crash
Problem: parallel repair (myisam_repair_threads > 1) of a myisam
table with two or more fulltext keys that use the same parser may
lead to a server crash. ALTER TABLE ENABLE KEYS is affected as well.
Fix: properly initialize fulltext structures for parallel repair.
Note: 1. there's no deterministic test case.
2. now we call parser->init() for each fulltext key
(not for each fulltext parser used).

Add #define HAVE_CHARSET_name in config-win.h for all character sets that MySQL
supports. Add comments to config/ac-macros/character_sets.m4 and config-win.h
so hopefully they will be updated in sync.
