SIGINT is handled in funny ways on windows, which could lead to problems when
Control-C was pressed in the client during a long-running query. Now Control-C
during a query aborts that query (by sending KILL to the server on a second
connexion), while Control-C outside of a running query terminates the client.
"I want to have the current delimiter in the prompt so that I can know at
a glance which is set."
Add a 'l' format specifier that represents the current statement delimiter.
Old option ordering in the help was confusing to some users. Changed
ordering of deprecated options to be consistent, and added mention to
entry for options with a "--no-option" variant mentioning the
"--disable-option" variant.
do not look for client-specific commands while inside a multi-line comment.
we will allow multi-comments pretty much anywhere within SQL-statements,
but client-specific commands (help, use, print, ...) must be the first token
in the input.
Using \U or \u in a prompt with the mysql command-line client could
crash when connecting to the instance manager, since it does not return
information about the user when asked by the client. This is fixed by
having the client use what it knowns about the user (or giving up and
saying "(unknown)").
The problem happened because "mysql" didn't send mysql_select_db() if
the current active database was specified in USE.
Now it always send mysql_select_db().
Rebuilding of completion hash is skipped in the same db is used
(for performance purposes).
Correct a bug (that I introduced, after using Oracle's database software for
too many years) where the length of the database-sent data is incorrectly
used to infer NULLness.
- Add new function 'ssl_verify_server_cert' which is used if we are
connecting to the server with SSL. It will compare the hostname in
the server's cert against the hostname that we used when connecting
to the server. Will reject the connection if hostname does not match.
- Add new option "OPT_SSL_VERIFY_SERVER_CERT" to be passed to mysql_options
which will turn on checking of servers cert.
- Add new argument "ssl-verify-server-cert" to all mysql* clients which
will activate the above option.
- Generate a new server cert with 1024 bits that has "localhost" as the server name.
Lines with column names consisting of national letters
were wrongly formatted in "mysql --table" results:
mysql> SELECT 'xxx xxx xxx' as 'xxx xxx xxx';
+-------------------+
| xxx xxx xxx |
+-------------------+
| xxx xxx xxx |
+-------------------+
1 row in set (0.00 sec)
It happened because in UTF-8 (and other multibyte charsets)
the number of display cells is not always equal to the number
of bytes of the string.
Data lines (unlike column name lines) were formatted correctly,
because data lines were displayed taking in account number of
display cells. This patch takes in account number of cells when
displaying column names, the same way like displaying data lines does.
Note: The patch is going to be applied to 4.1.
Test case will be added after merge to 5.0,
into "mysql.test", which appeared in 5.0.
mysql.cc:
Adding column name allignment using numcells(),
the same to data alignment, which was implemented earlier.
does not have "NOT NULL" attribute set. Also, calculate the padding
characters more safely, so that a negative number doesn't cause it to
print MAXINT-n spaces.
