Client capability flags
Implementations
Use the improved version of Old Password Authentication. Assumed to be set since 4.1.1.
Send found rows instead of affected rows in EOF_Packet.
Don’t allow database.table.column.
Special handling of ODBC behavior.
Client only flag. Not used.
Client
Do not issue SIGPIPE if network failures occur (libmysqlclient only).
Enable authentication response packet to be larger than 255 bytes. When the ability to change default plugin require that the initial password field in the Protocol::HandshakeResponse41 paclet can be of arbitrary size. However, the 4.1 client-server protocol limits the length of the auth-data-field sent from client to server to 255 bytes. The solution is to change the type of the field to a true length encoded string and indicate the protocol change with this client capability flag.
Server
Understands length-encoded integer for auth response data in Protocol::HandshakeResponse41.
Client
Length of auth response data in Protocol::HandshakeResponse41 is a length-encoded integer.
Note
The flag was introduced in 5.6.6, but had the wrong value.
Capable of handling server state change information. Its a hint to the server to include the state change information in OK_Packet.
Server
Can set SERVER_SESSION_STATE_CHANGED in the SERVER_STATUS_flags_enum and send Session State Information in a OK_Packet.
Client
Expects the server to send Session State Information in a OK_Packet.
Client no longer needs EOF_Packet and will use OK_Packet instead.
Server
Can send OK after a Text Resultset.
Client
Expects an OK_Packet (instead of EOF_Packet) after the resultset rows of a Text Resultset.
Background
To support CLIENT_SESSION_TRACK, additional information must be sent after all successful commands. Although the OK_Packet is extensible, the EOF_Packet is not due to the overlap of its bytes with the content of the Text Resultset Row.
Therefore, the EOF_Packet in the Text Resultset is replaced with an OK_Packet. EOF_Packet is deprecated as of MySQL 5.7.5.
The client can handle optional metadata information in the resultset.
Compression protocol extended to support zstd compression method.
This capability flag is used to send zstd compression level between client and server provided both client and server are enabled with this flag.
Server
Server sets this flag when global variable protocol-compression-algorithms has zstd in its list of supported values.
Client
Client sets this flag when it is configured to use zstd compression method.
Support optional extension for query parameters into the COM_QUERY and COM_STMT_EXECUTE packets.
Server
Expects an optional part containing the query parameter set(s). Executes the query for each set of parameters or returns an error if more than 1 set of parameters is sent and the server can’t execute it.
Client
Can send the optional part containing the query parameter set(s).
Client or server supports progress reports within error packet.
Verify server certificate. Client only flag.
Deprecated in favor of –ssl-mode.
Don’t reset the options after an unsuccessful connect. Client only flag.
Returns an empty set of flags.
Returns the set containing all flags.
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Safety
The caller of the bitflags!
macro can chose to allow or
disallow extra bits for their bitflags type.
The caller of from_bits_unchecked()
has to ensure that
all bits correspond to a defined flag or that extra bits
are valid for this bitflags type.
Returns true
if there are flags common to both self
and other
.
Returns true
if all of the flags in other
are contained within self
.
Inserts the specified flags in-place.
Removes the specified flags in-place.
Toggles the specified flags in-place.
Inserts or removes the specified flags depending on the passed value.
Returns the intersection between the flags in self
and
other
.
Specifically, the returned set contains only the flags which are
present in both self
and other
.
This is equivalent to using the &
operator (e.g.
ops::BitAnd
), as in flags & other
.
Returns the union of between the flags in self
and other
.
Specifically, the returned set contains all flags which are
present in either self
or other
, including any which are
present in both (see Self::symmetric_difference
if that
is undesirable).
This is equivalent to using the |
operator (e.g.
ops::BitOr
), as in flags | other
.
Returns the difference between the flags in self
and other
.
Specifically, the returned set contains all flags present in
self
, except for the ones present in other
.
It is also conceptually equivalent to the “bit-clear” operation:
flags & !other
(and this syntax is also supported).
This is equivalent to using the -
operator (e.g.
ops::Sub
), as in flags - other
.
Returns the symmetric difference between the flags
in self
and other
.
Specifically, the returned set contains the flags present which
are present in self
or other
, but that are not present in
both. Equivalently, it contains the flags present in exactly
one of the sets self
and other
.
This is equivalent to using the ^
operator (e.g.
ops::BitXor
), as in flags ^ other
.
Returns the complement of this set of flags.
Specifically, the returned set contains all the flags which are
not set in self
, but which are allowed for this type.
Alternatively, it can be thought of as the set difference
between Self::all()
and self
(e.g. Self::all() - self
)
This is equivalent to using the !
operator (e.g.
ops::Not
), as in !flags
.
