lz4.cmake: Check if shared or static lz4 library has LZ4_compress_default
function and if it has define HAVE_LZ4_COMPRESS_DEFAULT.
fil_compress_page: If HAVE_LZ4_COMPRESS_DEFAULT is defined use
LZ4_compress_default function for compression if not use
LZ4_compress_limitedOutput function.
Introduced a innodb-page-compression.inc file for page compression
tests that will also search .ibd file to verify that pages
are compressed (i.e. used search string is not found). Modified
page compression tests to use this file.
Note that snappy method is not included because of MDEV-12615
InnoDB page compression method snappy mostly does not compress pages
that will be fixed on different commit.
Also, include fixes by Vladislav Vaintroub to the
aws_key_management plugin. The AWS C++ SDK specifically depends on
OPENSSL_LIBRARIES, not generic SSL_LIBRARIES (such as YaSSL).
Do not exporting mysqld entry points directly.
This is needed for mariabackup, to load encryption plugins on Windows.
All plugins are "pure" by default. To mark plugin "impure"
it should use RECOMPILE_FOR_EMBEDDED or STORAGE_ENGINE keyword.
in MYSQL_ADD_PLUGIN, do not add TARGET_LINK_LIBRARIES twice for the LINK_LIBRARIES parameter
It is usually harmless to add libraries twice.
However, aws_key_management uses -Wl,-whole-archive to workaround linker issues on Linux
If libraries are added twice with whole-archive, linking will fail complaining about duplicate symbols
debug build with older cmake.
The constant is implicitely defined by VS when chosen C runtime is Debug
(/MTd, MDd).
CMake does not define it since https://public.kitware.com/Bug/view.php?id=15777
was fixed.
We remove it from compile flags, to be able to build Debug with /MT runtime
using older cmakes.
To export symbols from the mysqld.exe, use lib.exe with /DEF, rather than
pre-link step when building mysqld.exe.
This helps to avoid relinking all plugins, if mysqld.exe was recompiled
but the list of its exports has not changed.
Also removed unnecessary DEPENDS in some ADD_CUSTOM_COMMAND (gen_lex_token,
gen_lex_hash etc). They confuse VS generator which tends to
recreate headers and do unnecessary recompilations.
Also, remove empty .ic files that were not removed by my MySQL commit.
Problem:
InnoDB used to support a compilation mode that allowed to choose
whether the function definitions in .ic files are to be inlined or not.
This stopped making sense when InnoDB moved to C++ in MySQL 5.6
(and ha_innodb.cc started to #include .ic files), and more so in
MySQL 5.7 when inline methods and functions were introduced
in .h files.
Solution:
Remove all references to UNIV_NONINL and UNIV_MUST_NOT_INLINE from
all files, assuming that the symbols are never defined.
Remove the files fut0fut.cc and ut0byte.cc which only mattered when
UNIV_NONINL was defined.
* define MYSQL_DYNAMIC_PLUGIN only for server plugins
* don't typedef my_bool in mysql.h if plugin.h has already done it
* fix the include guard in plugin.h
If page_compression (introduced in MariaDB Server 10.1) is enabled,
the logical action is to not preallocate space to the data files,
but to only logically extend the files with zeroes.
fil_create_new_single_table_tablespace(): Create smaller files for
ROW_FORMAT=COMPRESSED tables, but adhere to the minimum file size of
4*innodb_page_size.
fil_space_extend_must_retry(), os_file_set_size(): On Windows,
use SetFileInformationByHandle() and FILE_END_OF_FILE_INFO,
which depends on bumping _WIN32_WINNT to 0x0600.
FIXME: The files are not yet set up as sparse, so
this will currently end up physically extending (preallocating)
the files, wasting storage for unused pages.
os_file_set_size(): Add the parameter "bool sparse=false" to declare
that the file is to be extended logically, instead of being preallocated.
The only caller with sparse=true is
fil_create_new_single_table_tablespace().
(The system tablespace cannot be created with page_compression.)
fil_space_extend_must_retry(), os_file_set_size(): Outside Windows,
use ftruncate() to extend files that are supposed to be sparse.
On systems where ftruncate() is limited to files less than 4GiB
(if there are any), fil_space_extend_must_retry() retains the
old logic of physically extending the file.
Change output of mysql_config --libs to have -lmariadb instead of
-lmysqlclient
Static linking is not yet supported, because static library has different
base name ( libmariadbclient.a static vs libmariadb.so shared)
This change add WITH_ROCKSDB_{LZ4,BZIP2,ZSTD,snappy} CMake variables
that can be set to ON/OFF/AUTO.
If variable has default value AUTO, rocksdb links with corresponding
compression library. OFF disables compiling/linking with specific compression
library, ON forces compiling with it (cmake would throw error if library
is not available)
Support for ZLIB is added unconditionally, as it is always there.
