- Fix win64 pointer truncation warnings
(usually coming from misusing 0x%lx and long cast in DBUG)

- Also fix printf-format warnings

Make the above mentioned warnings fatal.

- fix pthread_join on Windows to set return value.

- The line was accidently removed by dd8474b1
- The effect of the missing test was just a few extra malloc when creating
  internal temporary tables. Nothing critical, but better got get fixed.

Update.rdiff fle

Also, introduce my_popen()/my_fgets() wrapper function for popen()/fgets()
in mysqltest to workaround a popen() bug in Windows C runtime,
mentioned in MDEV-9409

This workaround was used previously for "exec". From now on, it is also
used are used also for "perl" snippets.

reapply 6192f0bf

TSAN warnings count decreased from 206 to 195

- Clean up formulas and comments for host_cache_size and back_log
- Added test of autoset (for host_cache_size)
- Marked open_files_limit as auto_set

Ensure that no adaptive hash index exists for any system tables,
so that the blocked TRUNCATE TABLE t1 will not block the concurrent
TRUNCATE TABLE t2.

Made a few links in README.md secure (https).

This bug is a regression caused by the code refactoring in
commit f5a833c3. It was not present
in any release of the MariaDB server. The bug affects table-rebuilding
ALTER TABLE when the source table is in ROW_FORMAT=REDUNDANT and
contains no virtual columns.

row_log_table_low_redundant(): Log virtual column data only if
virtual columns are present.

The issue was that r_loops, r_rows and r_filtered in ANALYZE FORMAT= JSON were not
calculated for the table on which we were performing the MRR scan in the BKA join
Fixed this by adding respective counter in the JOIN_TAB_SCAN_MRR::open and JOIN_TAB_SCAN_MRR::next

The problem is there is an overflow for the key_file_length.
Added the maximum limit for the key_file_length

The ALTER TABLE…IMPORT TABLESPACE adjustment code that was introduced by
WL#5522 in MySQL 5.6 is incorrectly invoking rec_get_status() on a
ROW_FORMAT=REDUNDANT record to determine if a record is a leaf page record.
The function rec_get_status(rec) is only to be called on
ROW_FORMAT=COMPACT, DYNAMIC or COMPRESSED records.

Implement Field_timestamp::save_in_field(timestamp_field)
that stores timestamp values without converting them to MYSQL_TIME
and back, because this conversion is lossy around DST change time.
This fixes main.old-mode test.

This is 10.2 version of f8a800be

Implement a special Copy_func function for timestamps, that copies
timestamps without converting them to MYSQL_TIME (the conversion is
lossy around DST change time).

This fixes ALTER TABLE part of main.old-mode test.

This is 10.2 version of f4f48e06

make insert NULL into a timestamp mark the field as having an
explicit value. So that the field won't be assigned the value
again in TABLE::update_default_field()

make Item_func_now_local::save_in_field(timestamp_field) not to go
through MYSQL_TIME - this conversion is lossy around DST change times.
This fixes inserting a default value into a timestamp field.

log_group_read_log_seg(): Only display the message during recovery,
not during normal operation. When the XtraDB configuration parameter
innodb_log_archive is set, this function will be called during
normal operation.

But without f4f48e06..f8a800be - fixes for MDEV-12672
and related issues. 10.2 specific fix follows...

don't do it via MYSQL_TIME, that conversion is lossy
around DST change dates.

Implement a special Copy_field method for timestamps, that copies
timestamps without converting them to MYSQL_TIME (the conversion
is lossy around DST change dates).

libmariadbclient_18 version nodes, specially for debian builds

followup for 378beed0 - only count WARN_LEVEL_ERROR,
not warnings or notes.

tabtyp was defined under ODBC_SUPPORT, but used
outside of it too (under JDBC_SUPPORT).

Even if cmake can find pkg-config (e.g the one supplied with strawberry perl
), we cannot link with pkg-config-found libraries or use the headers -they
are mingw, 32bit-only.

- Added missing test case for MyISAM

Node pointer recors contain dict_index_get_n_unique_in_tree_nonleaf(index)+1
instead of index->n_uniq+1 fields.

rec_get_offsets_func(): Remove the incorrect assertion. Later in
the function there are assertion for checking the exact field count.

don't prepare for checking view's CHECK OPTION, if
there is no CHECK OPTION in the first place.
