## Version 1.2 (2014-06-03)
|
||||
|
||||
Changes:
|
||||
|
||||
- We switched back to a "rolling release". `go get` installs the current master branch again
|
||||
- Version v1 of the driver will not be maintained anymore. Go 1.0 is no longer supported by this driver
|
||||
- Exported errors to allow easy checking from application code
|
||||
- Enabled TCP Keepalives on TCP connections
|
||||
- Optimized INFILE handling (better buffer size calculation, lazy init, ...)
|
||||
- The DSN parser also checks for a missing separating slash
|
||||
- Faster binary date / datetime to string formatting
|
||||
- Also exported the MySQLWarning type
|
||||
- mysqlConn.Close returns the first error encountered instead of ignoring all errors
|
||||
- writePacket() automatically writes the packet size to the header
|
||||
- readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets
|
||||
|
||||
New Features:
|
||||
|
||||
- `RegisterDial` allows the usage of a custom dial function to establish the network connection
|
||||
- Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter
|
||||
- Logging of critical errors is configurable with `SetLogger`
|
||||
- Google CloudSQL support
|
||||
|
||||
Bugfixes:
|
||||
|
||||
- Allow more than 32 parameters in prepared statements
|
||||
- Various old_password fixes
|
||||
- Fixed TestConcurrent test to pass Go's race detection
|
||||
- Fixed appendLengthEncodedInteger for large numbers
|
||||
- Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo)
|
||||
|
||||
|
||||
## Version 1.1 (2013-11-02)
|
||||
|
||||
Changes:
|
||||
|
||||
- Go-MySQL-Driver now requires Go 1.1
|
||||
- Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
|
||||
- Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
|
||||
- `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
|
||||
- DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
|
||||
- Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
|
||||
- Optimized the buffer for reading
|
||||
- stmt.Query now caches column metadata
|
||||
- New Logo
|
||||
- Changed the copyright header to include all contributors
|
||||
- Improved the LOAD INFILE documentation
|
||||
- The driver struct is now exported to make the driver directly accessible
|
||||
- Refactored the driver tests
|
||||
- Added more benchmarks and moved all to a separate file
|
||||
- Other small refactoring
|
||||
|
||||
New Features:
|
||||
|
||||
- Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
|
||||
- Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
|
||||
- Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
|
||||
|
||||
Bugfixes:
|
||||
|
||||
- Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
|
||||
- Convert to DB timezone when inserting `time.Time`
|
||||
- Splitted packets (more than 16MB) are now merged correctly
|
||||
- Fixed false positive `io.EOF` errors when the data was fully read
|
||||
- Avoid panics on reuse of closed connections
|
||||
- Fixed empty string producing false nil values
|
||||
- Fixed sign byte for positive TIME fields

In general you should use an Unix domain socket if available and TCP otherwise for best performance.

|
||||
#### Address
|
||||
For TCP and UDP networks, addresses have the form `host:port`.
|
||||
For TCP and UDP networks, addresses have the form `host[:port]`.
|
||||
If `port` is omitted, the default port will be used.
|

If `host` is a literal IPv6 address, it must be enclosed in square brackets.
|
||||
The functions [net.JoinHostPort](http://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](http://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.

|
||||
|

For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
|
||||
|
||||
#### Parameters
|
||||
***Parameters are case-sensitive!***
|
||||
*Parameters are case-sensitive!*
|
||||
|
||||
Possible Parameters are:
|
||||
* `timeout`: **Driver** side connection timeout. The value must be a string of decimal numbers, each with optional fraction and a unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. To set a server side timeout, use the parameter [`wait_timeout`](http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_wait_timeout).
|
||||
* `charset`: Sets the charset used for client-server interaction ("SET NAMES `value`"). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
|
||||
* `allowAllFiles`: `allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files. *Might be insecure!*
|
||||
Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`.
|
||||
|
||||
##### `allowAllFiles`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
`allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files.
|
||||
[*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)
|
||||
|
||||
##### `allowCleartextPasswords`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
`allowCleartextPasswords=true` allows using the [cleartext client side plugin](http://dev.mysql.com/doc/en/cleartext-authentication-plugin.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.
|
||||
|
||||
##### `allowNativePasswords`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: true
|
||||
```
|
||||
`allowNativePasswords=false` disallows the usage of MySQL native password method.
|
||||
|
||||
##### `allowOldPasswords`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords).
|
||||
|
||||
##### `charset`
|
||||
|
||||
```
|
||||
Type: string
|
||||
Valid Values: <name>
|
||||
Default: none
|
||||
```
|
||||
|
||||
Sets the charset used for client-server interaction (`"SET NAMES <value>"`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
|
||||
|
||||
Usage of the `charset` parameter is discouraged because it issues additional queries to the server.
|
||||
Unless you need the fallback behavior, please use `collation` instead.
|
||||
|
||||
##### `collation`
|
||||
|
||||
```
|
||||
Type: string
|
||||
Valid Values: <name>
|
||||
Default: utf8_general_ci
|
||||
```
|
||||
|
||||
Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
|
||||
|
||||
A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
|
||||
|
||||
##### `clientFoundRows`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed.
|
||||
|
||||
##### `columnsWithAlias`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example:
|
||||
|
||||
```
|
||||
SELECT u.id FROM users as u
|
||||
```
|
||||
|
||||
will return `u.id` instead of just `id` if `columnsWithAlias=true`.
|
||||
|
||||
##### `interpolateParams`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`.
|
||||
|
||||
*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are blacklisted as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!*
|
||||
|
||||
##### `loc`
|
||||
|
||||
```
|
||||
Type: string
|
||||
Valid Values: <escaped name>
|
||||
Default: UTC
|
||||
```
|
||||
|
||||
Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](https://golang.org/pkg/time/#LoadLocation) for details.
|
||||
|
||||
Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter.
|
||||
|
||||
Please keep in mind, that param values must be [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`.
|
||||
|
||||
##### `maxAllowedPacket`
|
||||
```
|
||||
Type: decimal number
|
||||
Default: 4194304
|
||||
```
|
||||
|
||||
Max packet size allowed in bytes. The default value is 4 MiB and should be adjusted to match the server settings. `maxAllowedPacket=0` can be used to automatically fetch the `max_allowed_packet` variable from server *on every connection*.
|
||||
|
||||
##### `multiStatements`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded.
|
||||
|
||||
When `multiStatements` is used, `?` parameters must only be used in the first statement.
|
||||
|
||||
##### `parseTime`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
|
||||
The date or datetime like `0000-00-00 00:00:00` is converted into zero value of `time.Time`.
|
||||
|
||||
|
||||
##### `readTimeout`
|
||||
|
||||
```
|
||||
Type: duration
|
||||
Default: 0
|
||||
```
|
||||
|
||||
I/O read timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
|
||||
|
||||
##### `rejectReadOnly`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
|
||||
`rejectReadOnly=true` causes the driver to reject read-only connections. This
|
||||
is for a possible race condition during an automatic failover, where the mysql
|
||||
client gets connected to a read-only replica after the failover.
|
||||
|
||||
Note that this should be a fairly rare case, as an automatic failover normally
|
||||
happens when the primary is down, and the race condition shouldn't happen
|
||||
unless it comes back up online as soon as the failover is kicked off. On the
|
||||
other hand, when this happens, a MySQL application can get stuck on a
|
||||
read-only connection until restarted. It is however fairly easy to reproduce,
|
||||
for example, using a manual failover on AWS Aurora's MySQL-compatible cluster.
|
||||
|
||||
If you are not relying on read-only transactions to reject writes that aren't
|
||||
supposed to happen, setting this on some MySQL providers (such as AWS Aurora)
|
||||
is safer for failovers.
|
||||
|
||||
Note that ERROR 1290 can be returned for a `read-only` server and this option will
|
||||
cause a retry for that error. However the same error number is used for some
|
||||
other cases. You should ensure your application will never cause an ERROR 1290
|
||||
except for `read-only` mode when enabling this option.
|
||||
|
||||
|
||||
##### `serverPubKey`
|
||||
|
||||
```
|
||||
Type: string
|
||||
Valid Values: <name>
|
||||
Default: none
|
||||
```
|
||||
|
||||
Server public keys can be registered with [`mysql.RegisterServerPubKey`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterServerPubKey), which can then be used by the assigned name in the DSN.
|
||||
Public keys are used to transmit encrypted data, e.g. for authentication.
|
||||
If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required.
|
||||
|
||||
|
||||
##### `timeout`
|
||||
|
||||
```
|
||||
Type: duration
|
||||
Default: OS default
|
||||
```
|
||||
|
||||
Timeout for establishing connections, aka dial timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
|
||||
|
||||
|
||||
##### `tls`
|
||||
|
||||
```
|
||||
Type: bool / string
|
||||
Valid Values: true, false, skip-verify, <name>
|
||||
Default: false
|
||||
```
|
||||
|
||||
`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side). Use a custom value registered with [`mysql.RegisterTLSConfig`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).
|
||||
|
||||
|
||||
##### `writeTimeout`
|
||||
|
||||
```
|
||||
Type: duration
|
||||
Default: 0
|
||||
```
|
||||
|
||||
I/O write timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
|
||||
|
||||
|
||||
##### System Variables
|
||||
|
||||
Any other parameters are interpreted as system variables:
|
||||
* `<boolean_var>=<value>`: `SET <boolean_var>=<value>`
|
||||
* `<enum_var>=<value>`: `SET <enum_var>=<value>`
|
||||
* `<string_var>=%27<value>%27`: `SET <string_var>='<value>'`
|
||||
|
||||
Rules:
|
||||
* The values for string variables must be quoted with `'`.
|
||||
* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!
|
||||
(which implies values of string variables must be wrapped with `%27`).
|
||||
|
||||
Examples:
|
||||
* `autocommit=1`: `SET autocommit=1`
|
||||
* [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'`
|
||||
* [`tx_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `SET tx_isolation='REPEATABLE-READ'`
|
||||
|

### Connection pool and timeouts
|
||||
The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.
|
||||
|
||||
## `ColumnType` Support
|
||||
This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported.
|
||||
|
||||
## `context.Context` Support
|
||||
Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
|
||||
See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.
|
||||
|
||||
|
||||
### `LOAD DATA LOCAL INFILE` support
|
||||
For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
|
||||
```go
|
||||
import "github.com/go-sql-driver/mysql"
|
||||
```
|
||||
|
||||
Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` (might be insecure).
|
||||
Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)).
|
||||
|
||||
To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then.
|
||||
To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore.
|
||||

||||

||||
See the [godoc of Go-MySQL-Driver](https://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details.
|
||||
|
||||
|
||||
### `time.Time` support
|
||||
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
|
||||
|
||||
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
|
||||
|
||||
**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
|
||||
|
||||
Alternatively you can use the [`NullTime`](https://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
|
||||
|
||||
|
||||
### Unicode support
|
||||
Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default.
|
||||
|
||||
Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
|
||||
|
||||
Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
|
||||
|
||||
See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support.
|
||||
|
||||
## Testing / Development
|
||||
To run the driver tests you may need to adjust the configuration. See [this Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
