-
-Package imaging provides basic image manipulation functions (resize, rotate, flip, crop, etc.).
-This package is based on the standard Go image package and works best along with it.
-
-Image manipulation functions provided by the package take any image type
-that implements `image.Image` interface as an input, and return a new image of
-`*image.NRGBA` type (32bit RGBA colors, not premultiplied by alpha).
-
-## Installation
-
-Imaging requires Go version 1.2 or greater.
-
- go get -u github.com/disintegration/imaging
-
-## Documentation
-
-http://godoc.org/github.com/disintegration/imaging
-
-## Usage examples
-
-A few usage examples can be found below. See the documentation for the full list of supported functions.
-
-### Image resizing
-```go
-// resize srcImage to size = 128x128px using the Lanczos filter
-dstImage128 := imaging.Resize(srcImage, 128, 128, imaging.Lanczos)
-
-// resize srcImage to width = 800px preserving the aspect ratio
-dstImage800 := imaging.Resize(srcImage, 800, 0, imaging.Lanczos)
-
-// scale down srcImage to fit the 800x600px bounding box
-dstImageFit := imaging.Fit(srcImage, 800, 600, imaging.Lanczos)
-
-// resize and crop the srcImage to fill the 100x100px area
-dstImageFill := imaging.Fill(srcImage, 100, 100, imaging.Center, imaging.Lanczos)
-```
-
-Imaging supports image resizing using various resampling filters. The most notable ones:
-- `NearestNeighbor` - Fastest resampling filter, no antialiasing.
-- `Box` - Simple and fast averaging filter appropriate for downscaling. When upscaling it's similar to NearestNeighbor.
-- `Linear` - Bilinear filter, smooth and reasonably fast.
-- `MitchellNetravali` - А smooth bicubic filter.
-- `CatmullRom` - A sharp bicubic filter.
-- `Gaussian` - Blurring filter that uses gaussian function, useful for noise removal.
-- `Lanczos` - High-quality resampling filter for photographic images yielding sharp results, but it's slower than cubic filters.
-
-The full list of supported filters: NearestNeighbor, Box, Linear, Hermite, MitchellNetravali, CatmullRom, BSpline, Gaussian, Lanczos, Hann, Hamming, Blackman, Bartlett, Welch, Cosine. Custom filters can be created using ResampleFilter struct.
-
-**Resampling filters comparison**
-
-Original image. Will be resized from 512x512px to 128x128px.

-Filter | Resize result
----|---
-`imaging.NearestNeighbor` | 
-`imaging.Box` | 
-`imaging.Linear` | 
-`imaging.MitchellNetravali` | 
-`imaging.CatmullRom` | 
-`imaging.Gaussian` | 
-`imaging.Lanczos` | 
-
-**Resize functions comparison**
-
-Original image:
-
-
-
-Resize the image to width=100px and height=100px:
-
-```go
-dstImage := imaging.Resize(srcImage, 100, 100, imaging.Lanczos)
-```
-
-
-Resize the image to width=100px preserving the aspect ratio:
-
-```go
-dstImage := imaging.Resize(srcImage, 100, 0, imaging.Lanczos)
-```
-
-
-Resize the image to fit the 100x100px boundng box preserving the aspect ratio:
-
-```go
-dstImage := imaging.Fit(srcImage, 100, 100, imaging.Lanczos)
-```
-
-
-Resize and crop the image with a center anchor point to fill the 100x100px area:
-
-```go
-dstImage := imaging.Fill(srcImage, 100, 100, imaging.Center, imaging.Lanczos)
-```
-
-
-### Gaussian Blur
-```go
-dstImage := imaging.Blur(srcImage, 0.5)
-```
-
-Sigma parameter allows to control the strength of the blurring effect.
-
-Original image | Sigma = 0.5 | Sigma = 1.5
----|---|---
- |  | 
-
-### Sharpening
-```go
-dstImage := imaging.Sharpen(srcImage, 0.5)
-```
-
-Uses gaussian function internally. Sigma parameter allows to control the strength of the sharpening effect.
-
-Original image | Sigma = 0.5 | Sigma = 1.5
----|---|---
- |  | 
-
-### Gamma correction
-```go
-dstImage := imaging.AdjustGamma(srcImage, 0.75)
-```
-
-Original image | Gamma = 0.75 | Gamma = 1.25
----|---|---
- |  | 
-
-### Contrast adjustment
-```go
-dstImage := imaging.AdjustContrast(srcImage, 20)
-```
-
-Original image | Contrast = 20 | Contrast = -20
----|---|---
- |  | 
-
-### Brightness adjustment
-```go
-dstImage := imaging.AdjustBrightness(srcImage, 20)
-```
-
-Original image | Brightness = 20 | Brightness = -20
----|---|---
- |  | 
-

-### Complete code example
-Here is the code example that loads several images, makes thumbnails of them
-and combines them together side-by-side.
-
-```go
-package main
-
-import (
- "image"
- "image/color"
-
- "github.com/disintegration/imaging"
-)
-
-func main() {
-

- img, err := imaging.Open(file)
- if err != nil {
- panic(err)
- }
- thumb := imaging.Thumbnail(img, 100, 100, imaging.CatmullRom)
- thumbnails = append(thumbnails, thumb)
- }
-
- // create a new blank image
- dst := imaging.New(100*len(thumbnails), 100, color.NRGBA{0, 0, 0, 0})
-
- // paste thumbnails into the new image side by side
- for i, thumb := range thumbnails {
- dst = imaging.Paste(dst, thumb, image.Pt(i*100, 0))
- }
-
- // save the combined image to file
- err := imaging.Save(dst, "dst.jpg")
- if err != nil {
- panic(err)

Go doesn't really have objects, at least not in the classic Smalltalk/Java sense. There goes the "O". gorp doesn't know anything about the relationships between your structs (at least not yet). So the "R" is questionable too (but I use it in the name because, well, it seemed more clever). - -The "M" is alive and well.

The API's for v1 are stable and shouldn't change. Development takes place at the master branch. Althought the code in master should always compile and test successfully, it might break API's. We aim to maintain backwards compatibility, but API's and behaviour might be changed to fix a bug. Also note that API's that are new in the master branch can change until released as v2. - -If you want to use bleeding edge, use `github.com/go-gorp/gorp` as import path. - -## API Documentation - -Full godoc output from the latest v1 release is available here: - -https://godoc.org/gopkg.in/gorp.v1 - -For the latest code in master: - -https://godoc.org/github.com/go-gorp/gorp - -## Supported Go versions - -This package is compatible with the last 2 major versions of Go, at this time `1.3` and `1.4`. - -Any earlier versions are only supported on a best effort basis and can be dropped any time. -Go has a great compatibility promise. Upgrading your program to a newer version of Go should never really be a problem. - -## Quickstart - -```go -package main - -import ( - "database/sql" - "gopkg.in/gorp.v1" - _ "github.com/mattn/go-sqlite3" - "log" - "time" -) - -func main() { - // initialize the DbMap - dbmap := initDb() - defer dbmap.Db.Close() - - // delete any existing rows - err := dbmap.TruncateTables() - checkErr(err, "TruncateTables failed") - - // create two posts - p1 := newPost("Go 1.1 released!", "Lorem ipsum lorem ipsum") - p2 := newPost("Go 1.2 released!", "Lorem ipsum lorem ipsum") - - // insert rows - auto increment PKs will be set properly after the insert - err = dbmap.Insert(&p1, &p2) - checkErr(err, "Insert failed") - - // use convenience SelectInt - count, err := dbmap.SelectInt("select count(*) from posts") - checkErr(err, "select count(*) failed") - log.Println("Rows after inserting:", count) - - // update a row - p2.Title = "Go 1.2 is better than ever" - count, err = dbmap.Update(&p2) - checkErr(err, "Update failed") - log.Println("Rows updated:", count) - - // fetch one row - note use of "post_id" instead of "Id" since column is aliased - // - // Postgres users should use $1 instead of ?

For example: - -```go -type Names struct { - FirstName string - LastName string -} - -type WithEmbeddedStruct struct { - Id int64 - Names -} - -es := &WithEmbeddedStruct{-1, Names{FirstName: "Alice", LastName: "Smith"}} -err := dbmap.Insert(es) -``` - -See the `TestWithEmbeddedStruct` function in `gorp_test.go` for a full example. - -### Create/Drop Tables ### - -Automatically create / drop registered tables. This is useful for unit tests -but is entirely optional. You can of course use gorp with tables created manually, -or with a separate migration tool (like [goose](https://bitbucket.org/liamstask/goose) or [migrate](https://github.com/mattes/migrate)). - -```go -// create all registered tables -dbmap.CreateTables() - -// same as above, but uses "if not exists" clause to skip tables that are -// already defined -dbmap.CreateTablesIfNotExists() - -// drop -dbmap.DropTables() -``` - -### SQL Logging - -Optionally you can pass in a logger to trace all SQL statements. -I recommend enabling this initially while you're getting the feel for what -gorp is doing on your behalf. - -Gorp defines a `GorpLogger` interface that Go's built in `log.Logger` satisfies. -However, you can write your own `GorpLogger` implementation, or use a package such -as `glog` if you want more control over how statements are logged. - -```go -// Will log all SQL statements + args as they are run -// The first arg is a string prefix to prepend to all log messages -dbmap.TraceOn("[gorp]", log.New(os.Stdout, "myapp:", log.Lmicroseconds)) - -// Turn off tracing -dbmap.TraceOff() -``` - -### Insert - -```go -// Must declare as pointers so optional callback hooks -// can operate on your data, not copies -inv1 := &Invoice{0, 100, 200, "first order", 0} -inv2 := &Invoice{0, 100, 200, "second order", 0} - -// Insert your rows -err := dbmap.Insert(inv1, inv2) - -// Because we called SetKeys(true) on Invoice, the Id field -// will be populated after the Insert() automatically -fmt.Printf("inv1.Id=%d inv2.Id=%d\n", inv1.Id, inv2.Id) -``` - -### Update - -Continuing the above example, use the `Update` method to modify an Invoice: - -```go -// count is the # of rows updated, which should be 1 in this example -count, err := dbmap.Update(inv1) -``` - -### Delete - -If you have primary key(s) defined for a struct, you can use the `Delete` -method to remove rows: - -```go -count, err := dbmap.Delete(inv1) -``` - -### Select by Key - -Use the `Get` method to fetch a single row by primary key. It returns -nil if no row is found. - -```go -// fetch Invoice with Id=99 -obj, err := dbmap.Get(Invoice{}, 99) -inv := obj.(*Invoice) -``` - -### Ad Hoc SQL - -#### SELECT - -`Select()` and `SelectOne()` provide a simple way to bind arbitrary queries to a slice -or a single struct. - -```go -// Select a slice - first return value is not needed when a slice pointer is passed to Select() -var posts []Post -_, err := dbmap.Select(&posts, "select * from post order by id") - -// You can also use primitive types -var ids []string -_, err := dbmap.Select(&ids, "select id from post") - -// Select a single row. -// Returns an error if no row found, or if more than one row is found -var post Post -err := dbmap.SelectOne(&post, "select * from post where id=?", id) -``` - -Want to do joins? Just write the SQL and the struct. gorp will bind them: - -```go -// Define a type for your join -// It *must* contain all the columns in your SELECT statement -// -// The names here should match the aliased column names you specify -// in your SQL - no additional binding work required. simple. -// -type InvoicePersonView struct { - InvoiceId int64 - PersonId int64 - Memo string - FName string -} - -// Create some rows -p1 := &Person{0, 0, 0, "bob", "smith"} -dbmap.Insert(p1) - -// notice how we can wire up p1.Id to the invoice easily -inv1 := &Invoice{0, 0, 0, "xmas order", p1.Id} -dbmap.Insert(inv1) - -// Run your query -query := "select i.Id InvoiceId, p.Id PersonId, i.Memo, p.FName " + - "from invoice_test i, person_test p " + - "where i.PersonId = p.Id" - -// pass a slice to Select() -var list []InvoicePersonView -_, err := dbmap.Select(&list, query) - -// this should test true -expected := InvoicePersonView{inv1.Id, p1.Id, inv1.Memo, p1.FName} -if reflect.DeepEqual(list[0], expected) { - fmt.Println("Woot! My join worked!") -} -``` - -#### SELECT string or int64 - -gorp provides a few convenience methods for selecting a single string or int64. - -```go -// select single int64 from db (use $1 instead of ? for postgresql) -i64, err := dbmap.SelectInt("select count(*) from foo where blah=?", blahVal) - -// select single string from db: -s, err := dbmap.SelectStr("select name from foo where blah=?", blahVal) - -``` - -#### Named bind parameters - -You may use a map or struct to bind parameters by name. This is currently -only supported in SELECT queries. - -```go -_, err := dbm.Select(&dest, "select * from Foo where name = :name and age = :age", map[string]interface{}{ - "name": "Rob", - "age": 31, -}) -``` - -#### UPDATE / DELETE - -You can execute raw SQL if you wish. Particularly good for batch operations. - -```go -res, err := dbmap.Exec("delete from invoice_test where PersonId=?", 10) -``` - -### Transactions - -You can batch operations into a transaction: - -```go -func InsertInv(dbmap *DbMap, inv *Invoice, per *Person) error { - // Start a new transaction - trans, err := dbmap.Begin() - if err != nil { - return err - } - - trans.Insert(per) - inv.PersonId = per.Id - trans.Insert(inv) - - // if the commit is successful, a nil error is returned - return trans.Commit() -} -``` - -### Hooks - -Use hooks to update data before/after saving to the db. Good for timestamps: - -```go -// implement the PreInsert and PreUpdate hooks -func (i *Invoice) PreInsert(s gorp.SqlExecutor) error { - i.Created = time.Now().UnixNano() - i.Updated = i.Created - return nil -} - -func (i *Invoice) PreUpdate(s gorp.SqlExecutor) error { - i.Updated = time.Now().UnixNano() - return nil -} - -// You can use the SqlExecutor to cascade additional SQL -// Take care to avoid cycles. gorp won't prevent them. -// -// Here's an example of a cascading delete -// -func (p *Person) PreDelete(s gorp.SqlExecutor) error { - query := "delete from invoice_test where PersonId=?" - - _, err := s.Exec(query, p.Id) - - if err != nil { - return err - } - return nil -} -``` - -Full list of hooks that you can implement: - - PostGet - PreInsert - PostInsert - PreUpdate - PostUpdate - PreDelete - PostDelete - - All have the same signature. for example: - - func (p *MyStruct) PostUpdate(s gorp.SqlExecutor) error - -### Optimistic Locking - -#### Note that this behaviour has changed in v2. See [Migration Guide](#migration-guide). - -gorp provides a simple optimistic locking feature, similar to Java's JPA, that -will raise an error if you try to update/delete a row whose `version` column -has a value different than the one in memory. This provides a safe way to do -"select then update" style operations without explicit read and write locks. - -```go -// Version is an auto-incremented number, managed by gorp -// If this property is present on your struct, update -// operations will be constrained -// -// For example, say we defined Person as: - -type Person struct { - Id int64 - Created int64 - Updated int64 - FName string - LName string - - // automatically used as the Version col - // use table.SetVersionCol("columnName") to map a different - // struct field as the version field - Version int64 -} - -p1 := &Person{0, 0, 0, "Bob", "Smith", 0} -dbmap.Insert(p1) // Version is now 1 - -obj, err := dbmap.Get(Person{}, p1.Id) -p2 := obj.(*Person) -p2.LName = "Edwards" -dbmap.Update(p2) // Version is now 2 - -p1.LName = "Howard" - -// Raises error because p1.Version == 1, which is out of date -count, err := dbmap.Update(p1) -_, ok := err.(gorp.OptimisticLockError) -if ok { - // should reach this statement - - // in a real app you might reload the row and retry, or - // you might propegate this to the user, depending on the desired - // semantics - fmt.Printf("Tried to update row with stale data: %v\n", err) -} else { - // some other db error occurred - log or return up the stack - fmt.Printf("Unknown db err: %v\n", err) -} -``` -### Adding INDEX(es) on column(s) beyond the primary key ### - -Indexes are frequently critical for performance. Here is how to add them to your tables. - -NB: SqlServer and Oracle need testing and possible adjustment to the -CreateIndexSuffix() and DropIndexSuffix() methods to make AddIndex() -work for them. - -In the example below we put an index both on the Id field, and on the AcctId field. - -``` -type Account struct { - Id int64 - AcctId string // e.g. this might be a long uuid for portability -} - -// indexType (the 2nd param to AddIndex call) is "Btree" or "Hash" for MySQL. -// demonstrate adding a second index on AcctId, and constrain that field to have unique values. -dbm.AddTable(iptab.Account{}).SetKeys(true, "Id").AddIndex("AcctIdIndex", "Btree", []string{"AcctId"}).SetUnique(true) - -err = dbm.CreateTablesIfNotExists() -checkErr(err, "CreateTablesIfNotExists failed") - -err = dbm.CreateIndex() -checkErr(err, "CreateIndex failed") - -``` -Check the effect of the CreateIndex() call in mysql: -``` -$ mysql - -MariaDB [test]> show create table Account; -+---------+--------------------------+ -| Account | CREATE TABLE `Account` ( - `Id` bigint(20) NOT NULL AUTO_INCREMENT, - `AcctId` varchar(255) DEFAULT NULL, - PRIMARY KEY (`Id`), - UNIQUE KEY `AcctIdIndex` (`AcctId`) USING BTREE <<<--- yes! index added. -) ENGINE=InnoDB DEFAULT CHARSET=utf8 -+---------+--------------------------+ - -``` - - -## Database Drivers - -gorp uses the Go 1 `database/sql` package. A full list of compliant drivers is available here: - -http://code.google.com/p/go-wiki/wiki/SQLDrivers - -Sadly, SQL databases differ on various issues. gorp provides a Dialect interface that should be -implemented per database vendor. Dialects are provided for: - -* MySQL -* PostgreSQL -* sqlite3 - -Each of these three databases pass the test suite. See `gorp_test.go` for example -DSNs for these three databases. - -Support is also provided for: - -* Oracle (contributed by @klaidliadon) -* SQL Server (contributed by @qrawl) - use driver: github.com/denisenkom/go-mssqldb - -Note that these databases are not covered by CI and I (@coopernurse) have no good way to -test them locally. So please try them and send patches as needed, but expect a bit more -unpredicability. - -## Known Issues - -### SQL placeholder portability - -Different databases use different strings to indicate variable placeholders in -prepared SQL statements. Unlike some database abstraction layers (such as JDBC), -Go's `database/sql` does not standardize this. - -SQL generated by gorp in the `Insert`, `Update`, `Delete`, and `Get` methods delegates -to a Dialect implementation for each database, and will generate portable SQL. - -Raw SQL strings passed to `Exec`, `Select`, `SelectOne`, `SelectInt`, etc will not be -parsed. Consequently you may have portability issues if you write a query like this: - -```go -// works on MySQL and Sqlite3, but not with Postgresql -err := dbmap.SelectOne(&val, "select * from foo where id = ?", 30) -``` - -In `Select` and `SelectOne` you can use named parameters to work around this. -The following is portable: - -```go -err := dbmap.SelectOne(&val, "select * from foo where id = :id", - map[string]interface{} { "id": 30}) -``` - -Additionally, when using Postgres as your database, you should utilize `$1` instead -of `?` placeholders as utilizing `?` placeholders when querying Postgres will result -in `pq: operator does not exist` errors. Alternatively, use -`dbMap.Dialect.BindVar(varIdx)` to get the proper variable binding for your dialect. - -### time.Time and time zones - -gorp will pass `time.Time` fields through to the `database/sql` driver, but note that -the behavior of this type varies across database drivers. - -MySQL users should be especially cautious. See: https://github.com/ziutek/mymysql/pull/77 - -To avoid any potential issues with timezone/DST, consider using an integer field for time -data and storing UNIX time. - -## Running the tests - -The included tests may be run against MySQL, Postgresql, or sqlite3. -You must set two environment variables so the test code knows which driver to -use, and how to connect to your database. - -```sh -# MySQL example: -export GORP_TEST_DSN=gomysql_test/gomysql_test/abc123 -export GORP_TEST_DIALECT=mysql - -# run the tests -go test - -# run the tests and benchmarks -go test -bench="Bench" -benchtime 10 -``` - -Valid `GORP_TEST_DIALECT` values are: "mysql"(for mymysql), "gomysql"(for go-sql-driver), "postgres", "sqlite" -See the `test_all.sh` script for examples of all 3 databases. This is the script I run -locally to test the library. - -## Performance - -gorp uses reflection to construct SQL queries and bind parameters. See the BenchmarkNativeCrud vs BenchmarkGorpCrud in gorp_test.go for a simple perf test. On my MacBook Pro gorp is about 2-3% slower than hand written SQL. - -## Migration guide -#### Pre-v2 to v2 -Automatic mapping of the version column used in optimistic locking has been removed as it could cause problems if the type was not int. The version column must now explicitly be set with tablemap.SetVersionCol(). - -## Help/Support - -IRC: #gorp -Mailing list: gorp-dev@googlegroups.com -Bugs/Enhancements: Create a github issue - -## Pull requests / Contributions - -Contributions are very welcome.

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 diff --git a/Godeps/_workspace/src/github.com/go-sql-driver/mysql/CONTRIBUTING.md b/Godeps/_workspace/src/github.com/go-sql-driver/mysql/CONTRIBUTING.md deleted file mode 100644 index f87c19824..000000000 --- a/Godeps/_workspace/src/github.com/go-sql-driver/mysql/CONTRIBUTING.md +++ /dev/null @@ -1,40 +0,0 @@ -# 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). - -Please provide the following minimum information: -* Your Go-MySQL-Driver version (or git SHA) -* Your Go version (run `go version` in your console) -* A detailed issue description -* Error Log if present -* If possible, a short example - - -## Contributing Code - -By contributing to this project, you share your code under the Mozilla Public License 2, as specified in the LICENSE file. -Don't forget to add yourself to the AUTHORS file. - -### Pull Requests Checklist - -Please check the following points before submitting your pull request: -- [x] Code compiles correctly -- [x] Created tests, if possible -- [x] All tests pass -- [x] Extended the README / documentation, if necessary -- [x] Added yourself to the AUTHORS file - -### Code Review - -Everyone is invited to review and comment on pull requests. -If it looks fine to you, comment with "LGTM" (Looks good to me). - -If changes are required, notice the reviewers with "PTAL" (Please take another look) after committing the fixes. - -Before merging the Pull Request, at least one [team member](https://github.com/go-sql-driver?tab=members) must have commented with "LGTM". - -## Development Ideas - -If you are looking for ideas for code contributions, please check our [Development Ideas](https://github.com/go-sql-driver/mysql/wiki/Development-Ideas) Wiki page. diff --git a/Godeps/_workspace/src/github.com/go-sql-driver/mysql/LICENSE b/Godeps/_workspace/src/github.com/go-sql-driver/mysql/LICENSE deleted file mode 100644 index 14e2f777f..000000000 --- a/Godeps/_workspace/src/github.com/go-sql-driver/mysql/LICENSE +++ /dev/null @@ -1,373 +0,0 @@ -Mozilla Public License Version 2.0 -================================== - -1.

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) - -##### `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. - -##### `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](http://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](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, <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`](http://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig). - - -##### System Variables - -All other parameters are interpreted as system variables: - * `autocommit`: `"SET autocommit=<value>"` - * [`time_zone`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `"SET time_zone=<value>"` - * [`tx_isolation`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `"SET tx_isolation=<value>"` - * `param`: `"SET <param>=<value>"` - -*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::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore. - -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.
