For that use: + +```go +testfixtures.New( + ... + testfixtures.Dialect("postgres"), // or "timescaledb" +) +``` + +With the above snippet this package will use `DISABLE TRIGGER` to temporarily +disabling foreign key constraints while loading fixtures. This work with any +version of PostgreSQL, but it is **required** to be connected in the database +as a SUPERUSER. You can make a PostgreSQL user a SUPERUSER with: + +```sql +ALTER USER your_user SUPERUSER; +``` + +#### With `ALTER CONSTRAINT` + +This approach don't require to be connected as a SUPERUSER, but only work with +PostgreSQL versions >= 9.4. Try this if you are getting foreign key violation +errors with the previous approach. It is as simple as using: + +```go +testfixtures.New( + ... + testfixtures.Dialect("postgres"), + testfixtures.UseAlterConstraint(), +) +``` + +Tested using the [github.com/lib/pq](https://github.com/lib/pq) driver. + +### MySQL / MariaDB + +Just make sure the connection string have +[the multistatement parameter](https://github.com/go-sql-driver/mysql#multistatements) +set to true, and use: + +```go +testfixtures.New( + ... + testfixtures.Dialect("mysql"), // or "mariadb" +) +``` + +Tested using the [github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql) driver. + +### SQLite + +SQLite is also supported. It is recommended to create foreign keys as +`DEFERRABLE` (the default) to prevent problems. See more +[on the SQLite documentation](https://www.sqlite.org/foreignkeys.html#fk_deferred). +(Foreign key constraints are no-op by default on SQLite, but enabling it is +recommended). + +```go +testfixtures.New( + ... + testfixtures.Dialect("sqlite"), +) +``` + +Tested using the [github.com/mattn/go-sqlite3](https://github.com/mattn/go-sqlite3) driver. + +### Microsoft SQL Server + +SQL Server support requires SQL Server >= 2008. Inserting on `IDENTITY` columns +are handled as well. Just make sure you are logged in with a user with +`ALTER TABLE` permission. + +```go +testfixtures.New( + ... + testfixtures.Dialect("sqlserver"), +) +``` + +Tested using the `mssql` and `sqlserver` drivers from the +[github.com/denisenkom/go-mssqldb](https://github.com/denisenkom/go-mssqldb) lib. + +## Templating + +Testfixtures supports templating, but it's disabled by default.

It may be useful to boostrap a test scenario from a sample +database of your app. + +```go +dumper, err := testfixtures.NewDumper( + testfixtures.DumpDatabase(db), + testfixtures.DumpDialect("postgres"), // or your database of choice + testfixtures.DumpDirectory("tmp/fixtures"), + textfixtures.DumpTables( // optional, will dump all table if not given + "posts", + "comments", + "tags", + ) +) +if err != nil { + ... +} +if err := dumper.Dump(); err != nil { + ... +} +``` + +> This was intended to run in small sample databases. It will likely break +if run in a production/big database. + +## Gotchas + +### Parallel testing + +This library doesn't yet support running tests in parallel! Running tests +in parallel can result in random data being present in the database, which +will likely cause tests to randomly/intermittently fail. + +This is specially tricky since it's not immediately clear that `go test ./...` +run tests for each package in parallel. If more than one package use this +library, you can face this issue. Please, use `go test -p 1 ./...` or run tests +for each package in separated commands to fix this issue. + +If you're looking into being able to run tests in parallel you can try using +testfixtures together with the [txdb][gotxdb] package, which allows wrapping +each test run in a transaction. + +## CLI + +We also have a CLI to load fixtures in a given database. +Grab it from the [releases page](https://github.com/go-testfixtures/testfixtures/releases) +and use it like: + +```bash +testfixtures -d postgres -c "postgres://user:password@localhost/database" -D testdata/fixtures +``` + +The connection string changes for each database driver. + +Use `--help` for all flags. + +## Contributing + +We recommend you to [install Task](https://taskfile.dev/#/installation) and +Docker before contributing to this package, since some stuff is automated +using these tools. + +It's recommended to use Docker Compose to run tests, since it runs tests for +all supported databases once. To do that you just need to run: + +```bash +task docker +``` + +But if you want to run tests locally, copy the `.sample.env` file as `.env` +and edit it according to your database setup. You'll need to create a database +(likely names `testfixtures_test`) before continuing. Then run the command +for the database you want to run tests against: + +```bash +task test:pg # PostgreSQL +task test:mysql # MySQL +task test:sqlite # SQLite +task test:sqlserver # Microsoft SQL Server +``` + +GitHub Actions (CI) runs the same Docker setup available locally. + +## Alternatives + +If you don't think using fixtures is a good idea, you can try one of these +packages instead: + +- [factory-go][factorygo]: Factory for Go.

This is different from libpq, which does not allow +run-time parameters in the connection string, instead requiring you to supply +them in the options parameter. + +For compatibility with libpq, the following special connection parameters are +supported: + + * dbname - The name of the database to connect to + * user - The user to sign in as + * password - The user's password + * host - The host to connect to. Values that start with / are for unix + domain sockets. (default is localhost) + * port - The port to bind to. (default is 5432) + * sslmode - Whether or not to use SSL (default is require, this is not + the default for libpq) + * fallback_application_name - An application_name to fall back to if one isn't provided. + * connect_timeout - Maximum wait for connection, in seconds. Zero or + not specified means wait indefinitely. + * sslcert - Cert file location. The file must contain PEM encoded data. + * sslkey - Key file location. The file must contain PEM encoded data. + * sslrootcert - The location of the root certificate file. The file + must contain PEM encoded data. + +Valid values for sslmode are: + + * disable - No SSL + * require - Always SSL (skip verification) + * verify-ca - Always SSL (verify that the certificate presented by the + server was signed by a trusted CA) + * verify-full - Always SSL (verify that the certification presented by + the server was signed by a trusted CA and the server host name + matches the one in the certificate) + +See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING +for more information about connection string parameters. + +Use single quotes for values that contain whitespace: + + "user=pqgotest password='with spaces'" + +A backslash will escape the next character in values: + + "user=space\ man password='it\'s valid'" + +Note that the connection parameter client_encoding (which sets the +text encoding for the connection) may be set but must be "UTF8", +matching with the same rules as Postgres. It is an error to provide +any other value. + +In addition to the parameters listed above, any run-time parameter that can be +set at backend start time can be set in the connection string. For more +information, see +http://www.postgresql.org/docs/current/static/runtime-config.html. + +Most environment variables as specified at http://www.postgresql.org/docs/current/static/libpq-envars.html +supported by libpq are also supported by pq.

The same marker can be reused for the same parameter: + + rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1 + OR age BETWEEN $2 AND $2 + 3`, "orange", 64) + +pq does not support the LastInsertId() method of the Result type in database/sql. +To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres +RETURNING clause with a standard Query or QueryRow call: + + var userid int + err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age) + VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid) + +For more details on RETURNING, see the Postgres documentation: + + http://www.postgresql.org/docs/current/static/sql-insert.html + http://www.postgresql.org/docs/current/static/sql-update.html + http://www.postgresql.org/docs/current/static/sql-delete.html + +For additional instructions on querying see the documentation for the database/sql package. + + +Data Types + + +Parameters pass through driver.DefaultParameterConverter before they are handled +by this package. When the binary_parameters connection option is enabled, +[]byte values are sent directly to the backend as data in binary format. + +This package returns the following types for values from the PostgreSQL backend: + + - integer types smallint, integer, and bigint are returned as int64 + - floating-point types real and double precision are returned as float64 + - character types char, varchar, and text are returned as string + - temporal types date, time, timetz, timestamp, and timestamptz are + returned as time.Time + - the boolean type is returned as bool + - the bytea type is returned as []byte + +All other types are returned directly from the backend as []byte values in text format. + + +Errors + + +pq may return errors of type *pq.Error which can be interrogated for error details: + + if err, ok := err.(*pq.Error); ok { + fmt.Println("pq error:", err.Code.Name()) + } + +See the pq.Error type for details. + + +Bulk imports + +You can perform bulk imports by preparing a statement returned by pq.CopyIn (or +pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement +handle can then be repeatedly "executed" to copy data into the target table. +After all data has been processed you should call Exec() once with no arguments +to flush all buffered data. Any call to Exec() might return an error which +should be handled appropriately, but because of the internal buffering an error +returned by Exec() might not be related to the data passed in the call that +failed. + +CopyIn uses COPY FROM internally. It is not possible to COPY outside of an +explicit transaction in pq. + +Usage example: + + txn, err := db.Begin() + if err != nil { + log.Fatal(err) + } + + stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age")) + if err != nil { + log.Fatal(err) + } + + for _, user := range users { + _, err = stmt.Exec(user.Name, int64(user.Age)) + if err != nil { + log.Fatal(err) + } + } + + _, err = stmt.Exec() + if err != nil { + log.Fatal(err) + } + + err = stmt.Close() + if err != nil { + log.Fatal(err) + } + + err = txn.Commit() + if err != nil { + log.Fatal(err) + } + + +Notifications + + +PostgreSQL supports a simple publish/subscribe model over database +connections. See http://www.postgresql.org/docs/current/static/sql-notify.html +for more information about the general mechanism. + +To start listening for notifications, you first have to open a new connection +to the database by calling NewListener. This connection can not be used for +anything other than LISTEN / NOTIFY. Calling Listen will open a "notification +channel"; once a notification channel is open, a notification generated on that +channel will effect a send on the Listener.Notify channel. A notification +channel will remain open until Unlisten is called, though connection loss might +result in some notifications being lost. To solve this problem, Listener sends +a nil pointer over the Notify channel any time the connection is re-established +following a connection loss. The application can get information about the +state of the underlying connection by setting an event callback in the call to +NewListener. + +A single Listener can safely be used from concurrent goroutines, which means +that there is often no need to create more than one Listener in your +application. However, a Listener is always connected to a single database, so +you will need to create a new Listener instance for every database you want to +receive notifications in. + +The channel name in both Listen and Unlisten is case sensitive, and can contain +any characters legal in an identifier (see +http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS +for more information). Note that the channel name will be truncated to 63 +bytes by the PostgreSQL server. + +You can find a complete, working example of Listener usage at +https://godoc.org/github.com/lib/pq/example/listen. + +*/ +package pq diff --git a/vendor/github.com/lib/pq/encode.go b/vendor/github.com/lib/pq/encode.go new file mode 100644 index 00000000..73cafb89 --- /dev/null +++ b/vendor/github.com/lib/pq/encode.go @@ -0,0 +1,602 @@ +package pq + +import ( + "bytes" + "database/sql/driver" + "encoding/binary" + "encoding/hex" + "errors" + "fmt" + "math" + "strconv" + "strings" + "sync" + "time" + + "github.com/lib/pq/oid" +) + +func binaryEncode(parameterStatus *parameterStatus, x interface{}) []byte { + switch v := x.(type) { + case []byte: + return v + default: + return encode(parameterStatus, x, oid.T_unknown) + } +} + +func encode(parameterStatus *parameterStatus, x interface{}, pgtypOid oid.Oid) []byte { + switch v := x.(type) { + case int64: + return strconv.AppendInt(nil, v, 10) + case float64: + return strconv.AppendFloat(nil, v, 'f', -1, 64) + case []byte: + if pgtypOid == oid.T_bytea { + return encodeBytea(parameterStatus.serverVersion, v) + } + + return v + case string: + if pgtypOid == oid.T_bytea { + return encodeBytea(parameterStatus.serverVersion, []byte(v)) + } + + return []byte(v) + case bool: + return strconv.AppendBool(nil, v) + case time.Time: + return formatTs(v) + + default: + errorf("encode: unknown type for %T", v) + } + + panic("not reached") +} + +func decode(parameterStatus *parameterStatus, s []byte, typ oid.Oid, f format) interface{} { + switch f { + case formatBinary: + return binaryDecode(parameterStatus, s, typ) + case formatText: + return textDecode(parameterStatus, s, typ) + default: + panic("not reached") + } +} + +func binaryDecode(parameterStatus *parameterStatus, s []byte, typ oid.Oid) interface{} { + switch typ { + case oid.T_bytea: + return s + case oid.T_int8: + return int64(binary.BigEndian.Uint64(s)) + case oid.T_int4: + return int64(int32(binary.BigEndian.Uint32(s))) + case oid.T_int2: + return int64(int16(binary.BigEndian.Uint16(s))) + case oid.T_uuid: + b, err := decodeUUIDBinary(s) + if err != nil { + panic(err) + } + return b + + default: + errorf("don't know how to decode binary parameter of type %d", uint32(typ)) + } + + panic("not reached") +} + +func textDecode(parameterStatus *parameterStatus, s []byte, typ oid.Oid) interface{} { + switch typ { + case oid.T_char, oid.T_varchar, oid.T_text: + return string(s) + case oid.T_bytea: + b, err := parseBytea(s) + if err != nil { + errorf("%s", err) + } + return b + case oid.T_timestamptz: + return parseTs(parameterStatus.currentLocation, string(s)) + case oid.T_timestamp, oid.T_date: + return parseTs(nil, string(s)) + case oid.T_time: + return mustParse("15:04:05", typ, s) + case oid.T_timetz: + return mustParse("15:04:05-07", typ, s) + case oid.T_bool: + return s[0] == 't' + case oid.T_int8, oid.T_int4, oid.T_int2: + i, err := strconv.ParseInt(string(s), 10, 64) + if err != nil { + errorf("%s", err) + } + return i + case oid.T_float4, oid.T_float8: + // We always use 64 bit parsing, regardless of whether the input text is for + // a float4 or float8, because clients expect float64s for all float datatypes + // and returning a 32-bit parsed float64 produces lossy results. + f, err := strconv.ParseFloat(string(s), 64) + if err != nil { + errorf("%s", err) + } + return f + } + + return s +} + +// appendEncodedText encodes item in text format as required by COPY +// and appends to buf +func appendEncodedText(parameterStatus *parameterStatus, buf []byte, x interface{}) []byte { + switch v := x.(type) { + case int64: + return strconv.AppendInt(buf, v, 10) + case float64: + return strconv.AppendFloat(buf, v, 'f', -1, 64) + case []byte: + encodedBytea := encodeBytea(parameterStatus.serverVersion, v) + return appendEscapedText(buf, string(encodedBytea)) + case string: + return appendEscapedText(buf, v) + case bool: + return strconv.AppendBool(buf, v) + case time.Time: + return append(buf, formatTs(v)...) + case nil: + return append(buf, "\\N"...) + default: + errorf("encode: unknown type for %T", v) + } + + panic("not reached") +} + +func appendEscapedText(buf []byte, text string) []byte { + escapeNeeded := false + startPos := 0 + var c byte + + // check if we need to escape + for i := 0;

before loading the -fixtures! It is supposed to be used on a test database. Please, double check -if you are running it against the correct database. - -Writing tests is hard, even more when you have to deal with an SQL database. -This package aims to make writing functional tests for web apps written in -Go easier. - -Basically this package mimics the ["Rails' way"][railstests] of writing tests -for database applications, where sample data is kept in fixtures files. Before -the execution of every test, the test database is cleaned and the fixture data -is loaded into the database. - -The idea is running tests against a real database, instead of relying in mocks, -which is boring to setup and may lead to production bugs not being caught in -the tests. - -## Installation - -First, get it: - -```bash -go get -u -v gopkg.in/testfixtures.v2 -``` - -## Usage - -Create a folder for the fixture files. Each file should contain data for a -single table and have the name `.yml`: - -``` -myapp/ - myapp.go - myapp_test.go - ... - fixtures/ - posts.yml - comments.yml - tags.yml - posts_tags.yml - ... -``` - -The file would look like this (it can have as many record you want): - -```yml -# comments.yml -- id: 1 - post_id: 1 - content: A comment... - author_name: John Doe - author_email: john@doe.com - created_at: 2016-01-01 12:30:12 - updated_at: 2016-01-01 12:30:12 - -- id: 2 - post_id: 2 - content: Another comment... - author_name: John Doe - author_email: john@doe.com - created_at: 2016-01-01 12:30:12 - updated_at: 2016-01-01 12:30:12 - -# ... -``` - -An YAML object or array will be converted to JSON.

If you want to disable this -check, use: - -```go -testfixtures.SkipDatabaseNameCheck(true) -``` - -## Sequences - -For PostgreSQL or Oracle, this package also resets all sequences to a high -number to prevent duplicated primary keys while running the tests. -The default is 10000, but you can change that with: - -```go -testfixtures.ResetSequencesTo(10000) -``` - -## Compatible databases - -### PostgreSQL - -This package has two approaches to disable foreign keys while importing fixtures -in PostgreSQL databases: - -#### With `DISABLE TRIGGER` - -This is the default approach. For that use: - -```go -&testfixtures.PostgreSQL{} -``` - -With the above snippet this package will use `DISABLE TRIGGER` to temporarily -disabling foreign key constraints while loading fixtures.

You can make a PostgreSQL user a SUPERUSER with: - -```sql -ALTER USER your_user SUPERUSER; -``` - -#### With `ALTER CONSTRAINT` - -This approach don't require to be connected as a SUPERUSER, but only work with -PostgreSQL versions >= 9.4. Try this if you are getting foreign key violation -errors with the previous approach. It is as simple as using: - -```go -&testfixtures.PostgreSQL{UseAlterConstraint: true} -``` - -#### Skipping reset of sequences - -You can skip the reset of PostgreSQL sequences if you're debugging a problem -with it, but most of the time you shouldn't do it: - -```go -&testfixtures.PostgreSQL{SkipResetSequences: true} -``` - -### MySQL / MariaDB - -Just make sure the connection string have -[the multistatement parameter](https://github.com/go-sql-driver/mysql#multistatements) -set to true, and use: - -```go -&testfixtures.MySQL{} -``` - -### SQLite - -SQLite is also supported. It is recommended to create foreign keys as -`DEFERRABLE` (the default) to prevent problems. See more -[on the SQLite documentation](https://www.sqlite.org/foreignkeys.html#fk_deferred). -(Foreign key constraints are no-op by default on SQLite, but enabling it is -recommended). - -```go -&testfixtures.SQLite{} -``` - -### Microsoft SQL Server - -SQL Server support requires SQL Server >= 2008. Inserting on `IDENTITY` columns -are handled as well. Just make sure you are logged in with a user with -`ALTER TABLE` permission. - -```go -&testfixtures.SQLServer{} -``` - -### Oracle - -Oracle is supported as well. Use: - -```go -&testfixtures.Oracle{} -``` - -## Generating fixtures for a existing database (experimental) - -The following code will generate a YAML file for each table of the database in -the given folder. It may be useful to boostrap a test scenario from a sample -database of your app. - -```go -err := testfixtures.GenerateFixtures(db, &testfixtures.PostgreSQL{}, "testdata/fixtures") -if err != nil { - log.Fatalf("Error generating fixtures: %v", err) -} -``` - -Or - -```go -err := testfixtures.GenerateFixturesForTables( - db, - []*TableInfo{ - &TableInfo{Name: "table_name", Where: "foo = 'bar'"}, - // ... - }, - &testfixtures.PostgreSQL{}, - "testdata/fixtures", -) -if err != nil { - log.Fatalf("Error generating fixtures: %v", err) -} -``` - -> This was thought to run in small sample databases. It will likely break -if run in a production/big database. - -## Gotchas - -### Parallel testing - -This library doesn't yet support running tests in parallel! Running tests -in parallel can result in random data being present in the database, which -will likely cause tests to randomly/intermittently fail. - -This is specially tricky since it's not immediately clear that `go test ./...` -run tests for each package in parallel. If more than one package use this -library, you can face this issue. Please, use `go test -p 1 ./...` or run tests -for each package in separated commands to fix this issue. - -See [#40](https://github.com/go-testfixtures/testfixtures/issues/40) -and [golang/go#11521](https://github.com/golang/go/issues/11521) for more information. - -We're also planning to implement transactional tests to allow running tests -in parallel (see [#24](https://github.com/go-testfixtures/testfixtures/issues/24)). -Running each test package in a separated database would also allow you to do that. -Open issues for other ideas :slightly_smiling_face:. - -## Contributing - -Tests were written to ensure everything work as expected. You can run the tests -with: - -```bash -# running tests for PostgreSQL -go test -tags postgresql - -# running test for MySQL -go test -tags mysql - -# running tests for SQLite -go test -tags sqlite - -# running tests for SQL Server -go test -tags sqlserver - -# running tests for Oracle -go test -tags oracle - -# running test for multiple databases at once -go test -tags 'sqlite postgresql mysql' - -# running tests + benchmark -go test -v -bench=. -tags postgresql -``` - -Travis runs tests for PostgreSQL, MySQL and SQLite. AppVeyor run for all -these and also Microsoft SQL Server. - -To set the connection string of tests for each database, copy the `.sample.env` -file as `.env` and edit it according to your environment. - -## Alternatives - -If you don't think using fixtures is a good idea, you can try one of these -packages instead: - -- [factory-go][factorygo]: Factory for Go. Inspired by Python's Factory Boy -and Ruby's Factory Girl -- [go-txdb (Single transaction SQL driver for Go)][gotxdb]: Use a single -database transaction for each functional test, so you can rollback to -previous state between tests to have the same database state in all tests -- [go-sqlmock][gosqlmock]: A mock for the sql.DB interface.
