DESCRIPTION
===========
If the .pid file is created at a world-writable location,
it can be compromised by replacing the server's pid with
another running server's (or some other non-mysql process)
PID causing abnormal behaviour.
ANALYSIS
========
In such a case, user should be warned that .pid file is
being created at a world-writable location.
FIX
===
A new function is_file_or_dir_world_writable() is defined
and it is called in create_pid_file() before .pid file
creation. If the location is world-writable, a relevant
warning is thrown.
NOTE
====
1. PID file is always created with permission bit 0664, so
for outside world its read-only.
2. Ignoring the case when permission is denied to get the
dir stats since the .pid file creation would fail anyway in
such a case.
Building with ninja shows the problem:

Bug#16877045 5.6-CLUSTER-7.3 WIN32 SQL_YACC.CC BUILD PROBLEM
- Somewhat circular dependency caused by the configured files sql_builtin.cc being included as
part of the files to generate in sql/
- Move sql_builtin.cc out of GEN_SOURCES variable.
- Create new variable CONF_SOURCES to be used for configured files.
- the probably ultimate fix for dependencies on VS
- remove some GET_TARGET_PROPERTY(LOCATION ...), they are deprecated in
cmake 3.9
- simplify signing targets on Windows.
- remove INSTALL_DEBUG_TARGET, we do not mix binaries from different builds
in the same package
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.
in default installation.
Added plugin-dir to the [client] section of the generated my.ini,
so that installed services (MSI or mysql_install_db.exe) would be able to
find plugin directory.

Bug#17959689: MAKE GCC AND CLANG GIVE CONSISTENT COMPILATION WARNINGS

Backport from mysql-5.6 to mysql-5.5
- Table locks now ends with state "After table lock"
- Open table now ends with state "After opening tables"
- All calls to close_thread_tables(), not only from mysql_execute_command(), has state "closing tables"
- Added state "executing" for mysql admin commands, like CACHE INDEX, REPAIR TABLE etc.
- Added state "Finding key cache" for CACHE INDEX
- Added state "Filling schema table" when we generate temporary table for SHOW commands and information schema.
Other things:
Add limit from innobase for thread_sleep_delay. This fixed a failing tests case.
Added db.opt to support-files to make 'make package' work
mysql-test/suite/funcs_1/datadict/processlist_val.inc:
Use new state
mysql-test/suite/funcs_1/r/processlist_priv_no_prot.result:
Updated test result because of new state
mysql-test/suite/funcs_1/r/processlist_val_no_prot.result:
Updated test result because of new state
sql/CMakeLists.txt:
Have option files in support-files
sql/lock.cc:
Added new state 'After table lock'
sql/sql_admin.cc:
Added state "executing" and "Sending data" for mysql admin commands, like CACHE INDEX, REPAIR TABLE etc.
Added state "Finding key cache"
sql/sql_base.cc:
open tables now ends with state "After table lock", instead of NULL
sql/sql_parse.cc:
Moved state "closing tables" to close_thread_tables()
sql/sql_show.cc:
Added state "Filling schema table" when we generate temporary table for SHOW commands and information schema.
storage/xtradb/buf/buf0buf.c:
Removed compiler warning
storage/xtradb/handler/ha_innodb.cc:
Add limit from innobase for thread_sleep_delay. This fixed a failing tests case.
support-files/db.opt:
cmakes needs this to create data/test directory
The merge is still missing a few hunks related to temporary tables and
InnoDB log file size. The associated code did not seem to exist in
10.0, so the merge of that needs more work. Until this is fixed, there
are a number of test failures as a result.
Adding ${CMAKE_BINARY_DIR}/pcre into search path for *.h files.
Needed for find pcre.h (which is generated from pcre.h.in) when
build directory != source directory.
cmake/jemalloc.cmake:
for dependencies to work, LIBJEMALLOC should be the target name, not the path
storage/tokudb/CMakeLists.txt:
* check the preconditions
* disable bdb tests (compilation errors)
* set variable, instead of SET_PROPERTY. same effect,
but doesn't fail when a plugin is disabled (that is, a target does not exist)
storage/tokudb/ft-index/CMakeLists.txt:
cmake should not look into examples/ directory,
there is hand-crafted examples/Makefile that
cmake will overwrite

storage/tokudb/ft-index/cmake_modules/TokuMergeLibs.cmake:
Libraries must be specified in the specific order,
REMOVE_DUPLICATES cannot be used, because it destroys this order.
(when OSLIBS contains "-lpthread -ljemalloc -lpthread", REMOVE_DUPLICATES
makes it "-lpthread -ljemalloc". But a thread library *must* be *after* jemalloc)
storage/tokudb/ft-index/cmake_modules/TokuSetupCTest.cmake:
* 'which' might print errors to stderr, they are not important, shut them up
* we don't have TOKUDB_DATA, no need to warn about it
* don't configure_file into itself (with input=output)
