Where package-wide types are available
--------------------------------------
- Variabe list type:
DECLARE var pkg1.type1;
- RETURN type for a package routine:
CREATE FUNCTION .. RETURN pkg1.type1 ...
- Parameter type for a package routine:
PROCEDURE p1(param1 pkg1.type1);
- Assoc array element type:
TYPE assoc1_t IS TABLE OF pkg1.type1 ...
- REF CURSOR RETURN type:
TYPE cur1_t IS REF CURSOR RETURN pkg1.type1;
Change details
--------------
- Adding a member Lex_length_and_dec_st::m_foreign_module_type
It's set to true when the data type was initialized from a TYPE
in foreign routine (e.g. in PACKAGE spec).
It's needed to prevent use of qualified identifiers in public contexts,
i.e. in schema public routine parameter types and schema publuc function
RETURN types.
Adding a helper method sp_head::check_applicability() which prevents
use of qualified types in public context.
- Adding a helper method sp_head::raise_unknown_data_type().
- Adding methods LEX::set_field_type_typedef_package_spec() for
2-step and 3-step qualified indentifiers.
It's used in field_type_all_with_typedefs which covers cases:
- Variabe list type : DECLARE var pkg1.type1;
- RETURN type : CREATE FUNCTION .. RETURN pkg1.type1 ...
- Parameter type : PROCEDURE p1(param1 pkg1.type1);
- Assoc array element type : TYPE assoc1_t IS TABLE OF pkg1.type1 ...
- Adding a method LEX::declare_type_ref_cursor_return_typedef().
It handles cases when a new TYPE REF CURSOR RETURN is declared,
for both for qualified RETURN types and non-qualified RETURN types:
- TYPE cur0_t IS REF CURSOR RETURN rec1_t;
- TYPE cur0_t IS REF CURSOR RETURN pkg1.rec1_t;
- TYPE cur0_t IS REF CURSOR RETURN db1.pkg1.rec1_t;
The code was moved from LEX::declare_type_ref_cursor() into
LEX::declare_type_ref_cursor_return_typedef() and extended
to cover qualified RETURN types.
- Adding a method Sql_path::find_package_spec_type().
It iterates through all schemas specified in @@path and searches
for the given type in the given package.
- Adding a helper method sp_pcontext::type_defs_add_ref_cursor()
to reuse the code.
- Adding a new method sp_package::get_typedef() to search
for TYPE definitions in PACKAGE specifications.
- Adding a new method sp_head::get_typedef_package_spec()
to search for TYPE definitions used by a PROCEDURE or FUNCTION.
- Adding a helper method
Sp_handler::sp_cache_routine_reentrant_suppress_errors
Adding a method Sp_handler::find_package_spec().
plugins are not yet supported in replay mode.
So, disabling tests type_test.type_test_int8, and type_test.type_test_double
to be run in replay-server mode
* reduced PARSEC_ITERATIONS_MAX because PKCS5_PBKDF2_HMAC() takes
a signed int
* instead of checking for '0'..'L' range (which includes punctuation,
check for the valid result of base62_to_uchar()
* add a connection test with non-default parsec_iterations
* make parsec_iterations a normal command line option
* update C/C to allow larger number of iterations in the client parsec
This patch adds a global and session level plugin variable
parsec_iterations to define the number of iterations to be
used when generating the key corresponding to the password.
It has a default value, lower and upper bounds.
THDVAR(thd, loc_info) can return NULL if the plugin was previously
uninstalled. get_loc_info() and its callers dereferenced it.
Guard against a NULL loc_info in get_loc_info(), auditing() and
log_current_query(). Such a session is not audited.
The plugin used clock() only to timestamp cache entries and measure
elapsed time against millisecond timeouts. As shown in MDEV-12345,
clock() is prohibitively expensive, and we do not need per-thread or
per-process CPU time here, only time differences.
Replace clock()/clock_t with the monotonic std::chrono::steady_clock.
Timeouts are kept as std::chrono::milliseconds
This statement:
OPEN c FOR 'dynamic sql'
was only allowed for SYS_REFCURSOR.
Additionally allow it for REF CURSOR with no RETURN clause, e.g.:
TYPE cur0_t IS REF CURSOR; -- No RETURN clause - OK for OPEN FOR
Note, REF CURSORs with RETURN clause are still not allowed for dynamic OPEN,
as expected.
Charset specified for XMLTYPE constructor.
Error returned if XML is in UTF16/UTF32 as we can't parse it yet.
XML check added so only well-formed allowed.
Field_xmltype::store has to do the my_error when it gets invalid XML,
just the warning with the -1 return results in the DBUG_ASSERT.
Also the UpdateXML function result reverted back to the STRING as
it can legally produce invalid XML, so we can't have columns built
from the UpdateXML to be XMLTYPE.
This statement:
OPEN strict_cursor_variable FOR 'SELECT ...';
caused an unclear error message:
ERROR 4078: Illegal parameter data types row<2> and row<0> for operation 'OPEN..FOR'
Fixing the error to be clearer:
ERROR HY000: Incorrect usage of c0 and OPEN..FOR <dynamic string>
Note, this statement is not supported:
OPEN strict_cursor_variable FOR 'SELECT ...';
It can be rewritten:
- either to use a SELECT statement instead of the dynamic string:
OPEN strict_cursor_variable FOR SELECT ...;
- or to make c0 a weak cursor variable (i.e.without the RETURN clause)
OPEN weak_cursor_variable FOR 'SELECT ...';
New optimizations were introduced that substitute virtual column
expressions (abbr. vcol expr) with index virtual columns (abbr. vcol
field) in ORDER BY and GROUP BY.
In this patch we introduce checks that the type of a vcol field is the
supertype to its vcol expr, and if not, do not proceed the
optimization. This ensures that the substitution is safe and does not
for example lose information due to truncation.
For simplicity, the version of the check implemented is strict with
100% precision, meaning that there are instances where vcol field is a
supertype to vcol expr, but the check returns false.
Type not covered in tests: Type_handler_null
Thanks to Jarir Khan <kjarir23@gmail.com> for initial patches
addressing this issue.
This reverts the effect of MDEV-21654 and includes
pam_mariadb_mtr in the mariadb-test-data Deb package.
This allows our CI systems to run tests on the
pam implementation on Debian systems.
As the pam configuration can include a full path,
we've change the installation of the pam module
pam_mariadb_mtr.so to under the /usr/lib*/plugins/test_pam_modules
directory and configured the pam configuration file,
suite/plugins/pam/mariadb_mtr, to include the
full path to pam_mariadb_mtr.so.
fix alloc_root() and my_malloc() to return 16-aligned pointers
(type_assoc_array.sp-assoc-array-64bit prints changes in memory_used,
and my_malloc() uses more memory now)
make sure P_S.{global|session}_status and I_S.feedback plugin table
have a column of the same width as I_S.global_status.
Otherwise long status strings (e.g. Ssl_cipher_list) won't fit
and trigger a data truncation warning (an error in the strict mode)
