Also, implement MDEV-11027 a little differently from 5.5 and 10.0:
recv_apply_hashed_log_recs(): Change the return type back to void
(DB_SUCCESS was always returned).
Report progress also via systemd using sd_notifyf().
Define my_thread_id as an unsigned type, to avoid mismatch with
ulonglong. Change some parameters to this type.
Use size_t in a few more places.
Declare many flag constants as unsigned to avoid sign mismatch
when shifting bits or applying the unary ~ operator.
When applying the unary ~ operator to enum constants, explictly
cast the result to an unsigned type, because enum constants can
be treated as signed.
In InnoDB, change the source code line number parameters from
ulint to unsigned type. Also, make some InnoDB functions return
a narrower type (unsigned or uint32_t instead of ulint;
bool instead of ibool).
mysql_prune_stmt_list() was walking the list following
element->next pointers, but inside the loop it was invoking
list_add(element) that modified element->next. So, mysql_prune_stmt_list()
failed to visit and reset all elements, and some of them were left
with pointers to invalid MYSQL.
FOUND
Description:- Failure during the validation of CA
certificate path which is provided as an option for 'ssl-ca'
returns two different errors for YaSSL and OPENSSL.
Analysis:- 'ssl-ca', option used for specifying the ssl ca
certificate path. Failing to validate this certificate with
OPENSSL returns an error, "ERROR 2026 (HY000): SSL
connection error: SSL_CTX_set_default_verify_paths failed".
While YASSL returns "ERROR 2026 (HY000): SSL connection
error: ASN: bad other signature confirmation". Error
returned by the OPENSSL is correct since
"SSL_CTX_load_verify_locations()" returns 0 (in case of
OPENSSL) for the failure and sets error as
"SSL_INITERR_BAD_PATHS". In case of YASSL,
"SSL_CTX_load_verify_locations()" returns an error number
which is less than or equal to 0 in case of error. Error
numbers for YASSL is mentioned in the file,
'extra/yassl/include/openssl/ssl.h'(line no : 292). Also
'ssl-ca' does not accept tilde home directory path
substitution.
Fix:- The condition which checks for the error in the
"SSL_CTX_load_verify_locations()" is changed in order to
accommodate YASSL as well. A logic is written in
"mysql_ssl_set()" in order accept the tilde home directory
path substitution for all ssl options.
The check for UCONTEXT in cmake was somehow become broken, disabling the
fallback to ucontext. This caused the non-blocking client API to not be
available for non-x86 platforms, on which no hand-crafted assembler
implementation of my_context is available.
