MDEV-23299: Bad data in mysql.func can cause crash
udf_init() can crash when the name field is empty.
We correct this by applying CHECK column constraints on
columns in the mysql.func tables.
The constrains are as follows:
* name cannot be an empty string;
* ret, the return type can be;
* STRING_RESULT(0),
* REAL_RESULT(1),
* INT_RESULT(2),
* and DECIMAL_RESULT(4);
* but not ROW_RESULT(3) or TIME_RESULT(5).
* dl, cannot be empty string
Upgrades ensure that any invalid functions are deleted.
- DEB_BUILD_HARDENING is only used with hardening-wrapper which is
deprecated in Debian, so remove it
- The word 'terse' should be checked in DEB_BUILD_OPTIONS and verbosity
controlled by it
- Remove excess build flag from debian/rules that does nothing, introduced
wrongly in commit 7cbde2d0a29e214afba4d5d30af890002fbf7db2. Instead
implement the embedded server build skipping on Travis-CI correctly.
- Simplify structure by doing all Travis-CI slimdown in one step.
- Remove unnecessary -e from sed, as it does nothing. When regex is needed,
use -r. Move -i to last so it is close to the file name it has an
argument.
- Remove backwards compat checks that are no longer relevant as neither
Debian Jessie (was before Stretch) nor Ubuntu Trusty (before Xenial)
are supported nor built for anymore. For example the GCC 4.8 check
if not relevant anymore, since Debian Jessie already has 4.9 and
Ubuntu Xenial has 5.3 and there is no GCC < 4.8 around anymore.
- Skip building ColumnStore on both Travis-CI and Gitlab-CI as it is
way too slow (time) and big (disk space) to pass.
- Remove unnecessary unused files
- Remove duplicate encryption configuration sample from sources and
re-use the identical file in RPM directory instead
- Clean away harmful "default-character-set = utf8mb4" from client config
as it is unnecassary (server enforces utf8mb4 anyway by default) and
could cause issues with mysqlbinlog and other tools (MDEV-22981).
- Update S3 plugin description to be long enough
- Remove trailing whitespace from support-files and Debian packaging.
- Clean away fixed Lintian issues
- Clean away temporary Salsa-CI fixes now that 10.5.4 is out and is fixed
- Apply wrap-and-sort -a -v

InnoDB appears to be invoking buf_flush_note_modification() on pages
that were exclusively latched but not modified in a mini-transaction.
MTR_MEMO_MODIFY, mtr_t::modify(): Define not only in debug code,
but also in release code. We will set the MTR_MEMO_MODIFY flag
on the earliest mtr_t::m_memo entry that we find.
MTR_LOG_NONE: Only use this mode in cases where the previous
mode will be restored before anything is modified in the mini-transaction.
MTR_MEMO_PAGE_X_MODIFY, MTR_MEMO_PAGE_SX_MODIFY: The allowed flag
combinations that include MTR_MEMO_MODIFY.
ReleaseBlocks: Only invoke buf_flush_note_modification()
on those buffer pool blocks on which mtr_t::set_modified()
and mtr_t::modify() were invoked.
