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 ## Version 1.0 (2013-05-14) Initial Release mysql-1.2/CONTRIBUTING.md000066400000000000000000000031071234342335300147550ustar00rootroot00000000000000# Contributing Guidelines ## Reporting Issues Before creating a new Issue, please check first if a similar Issue [already exists](https://github.com/go-sql-driver/mysql/issues?state=open) or was [recently closed](https://github.com/go-sql-driver/mysql/issues?direction=desc&page=1&sort=updated&state=closed).

License Grants and Conditions -------------------------------- 2.1. Grants Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license: (a) under intellectual property rights (other than patent or trademark) Licensable by such Contributor to use, reproduce, make available, modify, display, perform, distribute, and otherwise exploit its Contributions, either on an unmodified basis, with Modifications, or as part of a Larger Work; and (b) under Patent Claims of such Contributor to make, use, sell, offer for sale, have made, import, and otherwise transfer either its Contributions or its Contributor Version. 2.2. Effective Date The licenses granted in Section 2.1 with respect to any Contribution become effective for each Contribution on the date the Contributor first distributes such Contribution. 2.3. Limitations on Grant Scope The licenses granted in this Section 2 are the only rights granted under this License. No additional rights or licenses will be implied from the distribution or licensing of Covered Software under this License. Notwithstanding Section 2.1(b) above, no patent license is granted by a Contributor: (a) for any code that a Contributor has removed from Covered Software; or (b) for infringements caused by: (i) Your and any other third party's modifications of Covered Software, or (ii) the combination of its Contributions with other software (except as part of its Contributor Version); or (c) under Patent Claims infringed by Covered Software in the absence of its Contributions. This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be necessary to comply with the notice requirements in Section 3.4). 2.4. Subsequent Licenses No Contributor makes additional grants as a result of Your choice to distribute the Covered Software under a subsequent version of this License (see Section 10.2) or under the terms of a Secondary License (if permitted under the terms of Section 3.3). 2.5. Representation Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by this License. 2.6. Fair Use This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair dealing, or other equivalents. 2.7. Conditions Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1. 3. Responsibilities ------------------- 3.1. Distribution of Source Form All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients' rights in the Source Code Form. 3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then: (a) such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and (b) You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation --------------------------------------------------- If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination -------------- 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. ************************************************************************ * * * 6.

Miscellaneous ---------------- This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not be used to construe this License against a Contributor. 10. Versions of the License --------------------------- 10.1. New Versions Mozilla Foundation is the license steward. Except as provided in Section 10.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number. 10.2. Effect of New Versions You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, or under the terms of any subsequent version published by the license steward. 10.3. Modified Versions If you create software not governed by this License, and you want to create a new license for such software, you may create and use a modified version of this License if you rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License). 10.4.

No C-bindings, just pure Go * Connections over TCP/IPv4, TCP/IPv6 or Unix domain sockets * Automatic handling of broken connections * Automatic Connection Pooling *(by database/sql package)* * Supports queries larger than 16MB * Full [`sql.RawBytes`](http://golang.org/pkg/database/sql/#RawBytes) support. * Intelligent `LONG DATA` handling in prepared statements * Secure `LOAD DATA LOCAL INFILE` support with file Whitelisting and `io.Reader` support * Optional `time.Time` parsing ## Requirements * Go 1.1 or higher * MySQL (4.1+), MariaDB, Percona Server, Google CloudSQL or Sphinx (2.2.3+) --------------------------------------- ## Installation Simple install the package to your [$GOPATH](http://code.google.com/p/go-wiki/wiki/GOPATH "GOPATH") with the [go tool](http://golang.org/cmd/go/ "go command") from shell: ```bash $ go get github.com/go-sql-driver/mysql ``` Make sure [Git is installed](http://git-scm.com/downloads) on your machine and in your system's `PATH`. ## Usage _Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](http://golang.org/pkg/database/sql) API then. Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name) as `dataSourceName`: ```go import "database/sql" import _ "github.com/go-sql-driver/mysql" db, err := sql.Open("mysql", "user:password@/dbname") ``` [Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples"). ### DSN (Data Source Name) The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets): ``` [username[:password]@][protocol[(address)]]/dbname[?param1=value1&...¶mN=valueN] ``` A DSN in its fullest form: ``` username:password@protocol(address)/dbname?param=value ``` Except for the databasename, all values are optional. So the minimal DSN is: ``` /dbname ``` If you do not want to preselect a database, leave `dbname` empty: ``` / ``` This has the same effect as an empty DSN string: ``` ``` #### Password Passwords can consist of any character. Escaping is **not** necessary. #### Protocol See [net.Dial](http://golang.org/pkg/net/#Dial) for more information which networks are available. 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`. 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!* 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) ##### `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: Default: none ``` Sets the charset used for client-server interaction (`"SET NAMES "`). 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: 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. ##### `loc` ``` Type: string Valid Values: Default: UTC ``` Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](http://golang.org/pkg/time/#LoadLocation) for details. Please keep in mind, that param values must be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`. ##### `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` ##### `strict` ``` Type: bool Valid Values: true, false Default: false ``` `strict=true` enables the strict mode in which MySQL warnings are treated as errors. By default MySQL also treats notes as warnings. Use [`sql_notes=false`](http://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_sql_notes) to ignore notes. See the [examples](#examples) for an DSN example. ##### `timeout` ``` Type: decimal number Default: OS default ``` *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). ##### `tls` ``` Type: bool / string Valid Values: true, false, skip-verify, 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`](http://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig). ##### System Variables All other parameters are interpreted as system variables: * `autocommit`: `"SET autocommit="` * `time_zone`: `"SET time_zone="` * [`tx_isolation`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `"SET tx_isolation="` * `param`: `"SET ="` *The values must be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!* #### Examples ``` user@unix(/path/to/socket)/dbname ``` ``` root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local ``` ``` user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true ``` Use the [strict mode](#strict) but ignore notes: ``` user:password@/dbname?strict=true&sql_notes=false ``` TCP via IPv6: ``` user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci ``` TCP on a remote host, e.g. Amazon RDS: ``` id:password@tcp(your-amazonaws-uri.com:3306)/dbname ``` Google Cloud SQL on App Engine: ``` user@cloudsql(project-id:instance-name)/dbname ``` TCP using default port (3306) on localhost: ``` user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped ``` Use the default protocol (tcp) and host (localhost:3306): ``` user:password@/dbname ``` No Database preselected: ``` user:password@/ ``` ### `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!*](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::` then. See the [godoc of Go-MySQL-Driver](http://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 programm. 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](http://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`](http://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 the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details. Go-MySQL-Driver is not feature-complete yet. Your help is very appreciated. If you want to contribute, you can work on an [open issue](https://github.com/go-sql-driver/mysql/issues?state=open) or review a [pull request](https://github.com/go-sql-driver/mysql/pulls).
