Also, some MDEV-11738/MDEV-11581 post-push fixes.
In MariaDB 10.1, there is no fil_space_t::is_being_truncated field,
and the predicates fil_space_t::stop_new_ops and fil_space_t::is_stopping()
are interchangeable. I requested the fil_space_t::is_stopping() to be added
in the review, but some added checks for fil_space_t::stop_new_ops were
not replaced with calls to fil_space_t::is_stopping().
buf_page_decrypt_after_read(): In this low-level I/O operation, we must
look up the tablespace if it exists, even though future I/O operations
have been blocked on it due to a pending DDL operation, such as DROP TABLE
or TRUNCATE TABLE or other table-rebuilding operations (ALTER, OPTIMIZE).
Pass a parameter to fil_space_acquire_low() telling that we are performing
a low-level I/O operation and the fil_space_t::is_stopping() status should
be ignored.
To export symbols from the mysqld.exe, use lib.exe with /DEF, rather than
pre-link step when building mysqld.exe.
This helps to avoid relinking all plugins, if mysqld.exe was recompiled
but the list of its exports has not changed.
Also removed unnecessary DEPENDS in some ADD_CUSTOM_COMMAND (gen_lex_token,
gen_lex_hash etc). They confuse VS generator which tends to
recreate headers and do unnecessary recompilations.
vcols in the table definition are intentionaly bad and produce
warnings when a table is opened. In some cases (depending on the
TDC/TC state as left by earlier tests) a table might be opened in the
middle of the test, resulting in spurious warnings. Suppress them.
Also, don't run main.mdev-504 for ps-protocol at all (instead of
disabling ps-protocol inside the test, but still running the test)
remove hard-coded paths (that assumed we're in a source tree)
remove various shell/perl/awk/whatsnot scripts, use mysqltest and perl
remove numerous --exec /some/unix/tool commands, use mysqltest and perl
1. Special mode to search in error logs: if SEARCH_RANGE is not set,
the file is considered an error log and the search is performed
since the last CURRENT_TEST: line
2. Number of matches is printed too. "FOUND 5 /foo/ in bar".
Use greedy .* at the end of the pattern if number of matches
isn't stable. If nothing is found it's still "NOT FOUND",
not "FOUND 0".
3. SEARCH_ABORT specifies the prefix of the output.
Can be "NOT FOUND" or "FOUND" as before,
but also "FOUND 5 " if needed.
namely, restart_mysqld_with_option.inc and kill_and_restart_mysqld.inc -
use restart_mysqld.inc instead.
Also remove innodb_wl6501_crash_stripped.inc that wasn't used anywhere.
