The test encryption.innodb-redo-nokeys did not actually test
recovery without valid keys, because due to the setting
innodb_encrypt_tables, InnoDB refused to start up at all,
without even attempting any crash recovery.
fil_ibd_load(): If the encryption key is not available,
refuse to load the file.
As main() invokes parse_page() when -S or -D are set, it can be a case
when parse_page() is invoked when -D filename is not set, that is why
any attempt to write to page dump file must be done only if the file
name is set with -D.
The bug is caused by 2ef7a5a13a
(MDEV-13443).
A few regression tests invoke heavy flushing of the buffer pool
and may trigger warnings that tablespaces could not be deleted
because of pending writes. Those warnings are to be expected
during the execution of such tests.
The warnings are also frequently seen with Valgrind or MemorySanitizer.
For those, the global suppression in have_innodb.inc does the trick.
(Edits by SergeiP: fix encryption.tempfiles_encrypted, re-word comment)
Global ORDER BY clause of a UNION may not refer to 1) aggregate functions
or 2) window functions. setup_order() checked for #1 but not for #2.
(Backport Varun Gupta's patch + edit the commit comment)
Name resolution code produced errors for valid queries with window
functions (but not for queries which used aggregate functions as
window functions).
Name resolution code worked incorrectly, because window function
objects had is_window_func_sum_expr()=false. This was so, because
mark_as_window_func_sum_expr() was only called for aggregate functions
used as window functions.
The fix is to call it for any window function.
The InnoDB DATA DIRECTORY attribute is not implemented via
symbolic links but something similar, *.isl files that contain
the names of data files.
InnoDB failed to ignore the DATA DIRECTORY attribute even though
the server was started with --skip-symbolic-links.
Native ALTER TABLE in InnoDB will retain the DATA DIRECTORY attribute
of the table, no matter if the table will be rebuilt or not.
Generic ALTER TABLE (with ALGORITHM=COPY) as well as TRUNCATE TABLE
will discard the DATA DIRECTORY attribute.
All tests have been run with and without the ./mtr option
--mysqld=--skip-symbolic-links
and some tests that use the InnoDB DATA DIRECTORY attribute
have been adjusted for this.
fil_space_decrypt(): change signature to return status via dberr_t only.
Also replace impossible condition with an assertion and prove it via
test cases.
ALTER TABLE IMPORT doesn't properly handle instant alter metadata.
This patch makes IMPORT read, parse and apply instant alter metadata at the
very beginning of operation. So, cases when source table has some metadata
and destination table doesn't have it now works fine.
DISCARD already removes instant metadata so importing normal table into
instant table worked fine before this patch.
decrypt_decompress(): decrypts and decompresses page if needed
handle_instant_metadata(): this should be the first thing to read source
table. Basically, it applies instant metadata to a destination
dict_table_t object. This is the first thing to read FSP flags so
all possible checks of it were moved to this function.
PageConverter::update_index_page(): it doesn't now read instant metadata.
This logic were moved into handle_instant_metadata()
row_import::match_flags(): this is a first part row_import::match_schema().
As a separate function it's used by handle_instant_metadata().
fil_space_t::is_full_crc32_compressed(): added convenient function
ha_innobase::discard_or_import_tablespace(): do not reload table definition
to read instant metadata because handle_instant_metadata() does it better.
The reverted code was originally added in
4e7ee166a9
ANONYMOUS_VAR: this is a handy thing to use along with make_scope_exit()
full_crc32_import.test shows different results, because no
dict_table_close() and dict_table_open_on_id() happens.
Thus, SHOW CREATE TABLE shows a little bit older table definition.
Import operation without .cfg file fails when there is mismatch of index
between metadata table and .ibd file. Moreover, MDEV-19022 shows
that InnoDB can end up with index tree where non-leaf page has only
one child page. So it is unsafe to find the secondary index root page.
This patch does the following when importing the table without .cfg file:
1) If the metadata contains more than one index then InnoDB stops
the import operation and report the user to drop all secondary
indexes before doing import operation.
2) When the metadata contain only clustered index then InnoDB finds the
index id by reading page 0 & page 3 instead of traversing the
whole tablespace.
Problem:
=========
As a part of MDEV-14398 patch, InnoDB added and removed
the tablespace from default encrypt list. But InnoDB removes
the tablespace from the default encrypt list too early due to
i) other encryption thread working on the tablespace
ii) When tablespace is being flushed at the end of
key rotation
InnoDB fails to decrypt/encrypt the tablespace since
the tablespace removed too early and it leads to
test case failure.
Solution:
=========
Avoid the removal of tablespace from default_encrypt_list
only when
1) Another active encryption thread working on tablespace
2) Eligible for tablespace key rotation
3) Tablespace is in flushing phase
Removed the workaround in encryption.innodb_encryption_filekeys test case.
Set tests to non-valgrind:
oqgraph.social
encryption.innodb-page_encryption
binlog_encryption.encrypted_master
innodb.innodb-page_compression_lz4
main.lock_multi_bug38499
main.lock_multi_bug38691
- Set the innodb_encrypt_tables variable before
timeout happens. It will add the pending tablespace
to default encrypt list and does the encryption/decryption
based on innodb_encrypt_tables.
