privileges".
The first problem was that DROP USER didn't properly remove privileges
on stored functions from in-memory structures. So the dropped user
could have called stored functions on which he had privileges before
being dropped while his connection was still around.
Even worse if a new user with the same name was created he would
inherit privileges on stored functions from the dropped user.
Similar thing happened with old user name and function privileges
during RENAME USER.
This problem stemmed from the fact that the handle_grant_data() function
which handled DROP/RENAME USER didn't take any measures to update
in-memory hash with information about function privileges after
updating them on disk.
This patch solves this problem by adding code doing just that.
The second problem was that RENAME USER didn't properly update in-memory
structures describing table-level privileges and privileges on stored
procedures. As result such privileges could have been lost after a rename
(i.e. not associated with the new name of user) and inherited by a new
user with the same name as the old name of the original user.
This problem was caused by code handling RENAME USER in
handle_grant_struct() which [sic!]:
a) tried to update wrong (tables) hash when updating stored procedure
privileges for new user name.
b) passed wrong arguments to function performing the hash update and
didn't take into account the way in which such update could have
changed the order of the hash elements.
This patch solves this problem by ensuring that a) the correct hash
is updated, b) correct arguments are used for the hash_update()
function and c) we take into account possible changes in the order
of hash elements.
Details:
- Limit the queries to character sets and collations
which are most probably available in all build types.
But try to preserve the intention of the tests.
- Remove the variants adjusted to some build types.
Note:
1. The results of the review by Bar are included.
2. I am not able to check the correctness of this patch
on any existing build type and any MySQL version.
So it could happen that the new test fails somewhere.
including modifications according to code review
+ backport of the fix for
Bug 41932 funcs_1: is_collation_character_set_applicability path
too long for tar
which was missing in 5.0 (just a renaming of two files)
Test was failing due to the addition of a '\x05' character in result sets
Latest builds of the server have shown this problem to have disappeared.
Removing code within the test that disables the test on Mac OS X.
Recommit due to tree error on earlier, approved patch.
Bug#36787 Test funcs_1.charset_collation_1 failing
Details:
1. Skip charset_collation_1 if charset "ucs2_bin" is
missing (property which distincts "vanilla" builds
from the others)
2. Let builds with version_comment LIKE "%Advanced%"
(found them for 5.1) execute charset_collation_3.
3. Update comments charset_collation.inc so that they
reflect the current experiences.
Bug#37167 funcs_1: Many tests fail if the embedded server is used.
Bug#37164 funcs_1: Some tests fail if an optional character set is missing.
+ some cleanup within the testsuite related to the fixes above
+ some adjustments to open bugs on Mac OS X
Details:
- Remove the initial loading of data from tests if these data
are not somewhere retrieved
- Remove any use of columns with attribute unicode
(-> UCS2 is no more needed) from tests where unicode
properties are not checked or somehow required
- Create a separate branch of the Character maximum length test
(CML). If UCS2 is available than this test gets applied to
every available type of string column with attribute unicode
This prevents any loss of coverage by the points above.
- Disable the execution of is_tables_ndb which gives wrong
results because of a bug. Correct the exepected results of
this test.
- In case of tests failing when applied to the embedded server
1) Create a variant of this test for the embedded server
or
2) Skip the test in case of embedded server
depending on purpose and complexity of test.
- Skip the tests which could suffer from
Bug 28309 First insert violates unique constraint - was "memory" table empty ?
Bug 37380 Test funcs_1.is_columns_myisam_embedded fails on OS X
(both bugs Mac OS X, embedded server, MySQL 5.0 only)
- Minor improvements like remove typos
Fix for this bug and additional improvements/fixes
In detail:
- Remove unicode attribute from several columns
(unicode properties were nowhere needed/tested)
of the table tb3
-> The runnability of these tests depends no more on
the availibility of some optional collations.
- Use a table tb3 with the same layout for all
engines to be tested and unify the engine name
within the protocols.
-> <engine>_trig_<abc>.result have the same content
- Do not load data into tb3 if these rows have no
impact on result sets
- Add tests for NDB (they exist already in 5.1)
- "--replace_result" at various places because
NDB variants of tests failed with "random" row
order in results
This fixes a till now unknown weakness within the
funcs_1 NDB tests existing in 5.1 and 6.0
- Fix the expected result of ndb_trig_1011ext
which suffered from Bug 32656
+ disable this test
- funcs_1 could be executed with the mysql-test-run.pl
option "--reorder", which saves some runtime by
optimizing server restarts.
Runtimes on tmpfs (one attempt only):
with reorder 132 seconds
without reorder 183 seconds
- Adjust two "check" statements within func_misc.test
which were incorrect (We had one run with result set
difference though the server worked good.)
- minor fixes in comments
Bug#35335 funcs_1: Some tests fail within load_file during
pushbuild runs
Solution: 1. Move files with input data used in load_file,
load data etc.
from suite/funcs_1/<whatever>
to std_data
2. Use for testsuite funcs_1 the server option
--secure-file-priv=<MYSQLTEST_VARDIR>
3. Outfiles have to be stored under MYSQLTEST_VARDIR
+ changes according to WL#4304 Cleanup in funcs_1 tests
- backport of fixes/improvements made in 5.1 to 5.0
The differences between scripts in 5.0 and 5.1 cause
much additional and annoying work during any upmerge.
- replace error numbers with names
- improved comments
- improved formatting
- Unify storage engine names so that result files for
storage engine variants do not differ (some tests)
- remove a script no more used (tests are done in other scripts)
WL#4203 Reorganize and fix the data dictionary tests of
testsuite funcs_1
because the goal to fix
Bug#34532 Some funcs_1 tests do not clean up at end of testing
was partially missed.
Some minor additional modifications are for
WL#4304 Cleanup in funcs_1 tests
testsuite funcs_1
1. Fix the following bugs
Bug#30440 "datadict" tests (all engines) fail: Character sets depend on configuration
Solution: Test variants charset_collation_* adjusted to different builds
Bug#32603 "datadict" tests (all engines) fail in "community" tree: "PROFILING" table
Solution: Excluding "PROFILING" table from queries
Bug#33654 "slow log" is missing a line
Solution: Unify the content of the fields TABLES.TABLE_ROWS and
STATISTICS.CARDINALITY within result sets
Bug#34532 Some funcs_1 tests do not clean up at end of testing
Solution: DROP objects/reset global server variables modified during testing
+ let tests missing implementation end before loading of tables
Bug#31421 funcs_1: ndb__datadict fails, discrepancy between scripts and expected results
Solution: Cut <engine>__datadict tests into smaller tests + generate new results.
Bug#33599 INFORMATION_SCHEMA.STATISTICS got a new column INDEX_COMMENT: tests fail (2)
Generation of new results during post merge fix
Bug#33600 CHARACTER_OCTET_LENGTH is now CHARACTER_MAXIMUM_LENGTH * 4
Generation of new results during post merge fix
Bug#33631 Platform-specific replace of CHARACTER_MAXIMUM_LENGTH broken by 4-byte encoding
Generation of new results during post merge fix
+ removal of platform-specific replace routine (no more needed)
2. Restructure the tests
- Test not more than one INFORMATION_SCHEMA view per testscript
- Separate tests of I_S view layout+functionality from content related to the
all time existing databases "information_schema", "mysql" and "test"
- Avoid storage engine related variants of tests which are not sensible to
storage engines at all.
3. Reimplement or add some subtests + cleanup
There is a some probability that even the reviewed changeset
- does not fix all bugs from above or
- contains new bugs which show up on some platforms <> Linux or on one of
the various build types
4. The changeset contains fixes according to
- one code review
- minor bugs within testing code found after code review (accepted by reviewer)
- problems found during tests with 5.0.56 in build environment
Bug#31567 "datadict" tests (all engines) fail:
Reference protocol is non-standard build
Bug#30418 "datadict" tests (all engines) fail:
Dependency on the host name for ordering
Modifications:
1. The standard builds (build team) do not contain
the collation 'utf8_general_cs'.
The common developer builds (compuile-....-max)
contain this collation.
Solution fitting to both build variants:
Exclude the collation 'utf8_general_cs' from
result sets.
2. Use mysqltest builtin sorting of result set for
the statement where the hostname affects the
row order.
Bug#30418 "datadict" tests (all engines) fail: Dependency on the host name
for ordering
Bug#30420 "datadict" tests (all engines) fail: Release build has help tables loaded
Bug#30438 "{memory,myisam,ndb}__datadict" tests fail: Use "InnoDB" without checking
Bug#30440 "datadict" tests (all engines) fail: Character sets depend on configuration
Attention: Only the build team can check if Bug#30440 is really fixed.
- validated current result files
- forced order by and removed time stamps
removed a_version files (since do not make sense now when suite is in the main tree)
Note: datadict tests still fail as a result of regression bug 28181 in 5.0.42 (discovered
while performing this update) - tests should run clean once bug is fixed
