// It also bumps the minor version as the repository was wrongly already tagged

// 2019-12-26 v1.1.0-alpha.2: Second alpha release adds support for accessing a

// database concurrently by multiple goroutines and/or processes. v1.1.0 is now

// considered feature-complete. Next planed release should be a beta with a
|
|
// proper test suite.

//
|
|
// 2019-12-18 v1.1.0-alpha.1: First alpha release using the new cc/v3, gocc,
|
|
// qbe toolchain. Some primitive tests pass on linux_{amd64,386}. Not yet safe
|
|
// for concurrent access by multiple goroutines. Next alpha release is planed

|
// to arrive before the end of this year.

//
|

// To access a Sqlite database do something like
|
|
//
|
|
// import (
|
|
// "database/sql"
|
|
//
|
|
// _ "modernc.org/sqlite"
|

// ...
|
|
//
|
|
// # Debug and development versions
|
|
//
|
|
// A comma separated list of options can be passed to `go generate` via the
|
|
// environment variable GO_GENERATE. Some useful options include for example:
|
|
//
|
|
// -DSQLITE_DEBUG
|
|
// -DSQLITE_MEM_DEBUG
|
|
// -ccgo-verify-structs
|
|
//
|
|
// To create a debug/development version, issue for example:
|
|
//
|
|
// $ GO_GENERATE=-DSQLITE_DEBUG,-DSQLITE_MEM_DEBUG go generate
|
|
//
|
|
// Note: To run `go generate` you need to have modernc.org/ccgo/v3 installed.

//
|
|
// # Hacking
|
|
//
|
|
// This is an example of how to use the debug logs in modernc.org/libc when hunting a bug.
