From b9de9788f400484d26be5e9cc55b9f4c020ed096 Mon Sep 17 00:00:00 2001 From: kevinrizza Date: Tue, 15 Oct 2019 15:55:27 -0400 Subject: [PATCH 1/2] Database migration initialization This commit introduces a day 0 set of building blocks to implement a database migration framework into the sqlite database. Adding the following changes: - Introduce the `golang-migrate` project as a dependency and vendor it - Introduce a `db_migrations` folder with an initial no-op migration to bootstrap the initial database version for newly created databases - Update the initialization of the database when creating the initial schema to hard set the database migration version on db creation before loading any data This commit does not introduce a method of actually running future migrations against existing databases -- that is left for future implementation based on this groundwork when a set of commands that updates the database in place exists and requires the migration. The intention of this commit is also to ensure that future initialized registry databases have an initial version that can be used for migrations in future releases. --- cmd/configmap-server/main.go |

NilVersion? + NilMigration defines a migration without a body. NilVersion is defined as const -1. + +#### What is the difference between uint(version) and int(targetVersion)? + version refers to an existing migration version coming from a source and therefor can never be negative. + targetVersion can either be a version OR represent a NilVersion, which equals -1. + +#### What's the difference between Next/Previous and Up/Down? + ``` + 1_first_migration.up.extension next -> 2_second_migration.up.extension ... + 1_first_migration.down.extension <- previous 2_second_migration.down.extension ... + ``` + +#### Why two separate files (up and down) for a migration? + It makes all of our lives easier. No new markup/syntax to learn for users + and existing database utility tools continue to work as expected. + +#### How many migrations can migrate handle? + Whatever the maximum positive signed integer value is for your platform. + For 32bit it would be 2,147,483,647 migrations. Migrate only keeps references to + the currently run and pre-fetched migrations in memory. Please note that some + source drivers need to do build a full "directory" tree first, which puts some + heat on the memory consumption. + +#### Are the table tests in migrate_test.go bloated? + Yes and no. There are duplicate test cases for sure but they don't hurt here. In fact + the tests are very visual now and might help new users understand expected behaviors quickly. + Migrate from version x to y and y is the last migration? Just check out the test for + that particular case and know what's going on instantly. + +#### What is Docker being used for? + Only for testing. See [testing/docker.go](testing/docker.go) + +#### Why not just use docker-compose? + It doesn't give us enough runtime control for testing. We want to be able to bring up containers fast + and whenever we want, not just once at the beginning of all tests. + +#### Can I maintain my driver in my own repository? + Yes, technically thats possible. We want to encourage you to contribute your driver to this respository though. + The driver's functionality is dictated by migrate's interfaces. That means there should really + just be one driver for a database/ source. We want to prevent a future where several drivers doing the exact same thing, + just implemented a bit differently, co-exist somewhere on Github. If users have to do research first to find the + "best" available driver for a database in order to get started, we would have failed as an open source community. + +#### Can I mix multiple sources during a batch of migrations? + No. + +#### What does "dirty" database mean? + Before a migration runs, each database sets a dirty flag. Execution stops if a migration fails and the dirty state persists, + which prevents attempts to run more migrations on top of a failed migration. You need to manually fix the error + and then "force" the expected version. + +#### What happens if two programs try and update the database at the same time? +Database-specific locking features are used by *some* database drivers to prevent multiple instances of migrate from running migrations at the same time + the same database at the same time. For example, the MySQL driver uses the `GET_LOCK` function, while the Postgres driver uses + the `pg_advisory_lock` function. + +#### Do I need to create a table for tracking migration version used? +No, it is done automatically. + +#### Can I use migrate with a non-Go project? +Yes, you can use the migrate CLI in a non-Go project, but there are probably other libraries/frameworks available that offer better test and deploy integrations in that language/framework. \ No newline at end of file diff --git a/vendor/github.com/golang-migrate/migrate/v4/GETTING_STARTED.md b/vendor/github.com/golang-migrate/migrate/v4/GETTING_STARTED.md new file mode 100644 index 000000000..41f293cc7 --- /dev/null +++ b/vendor/github.com/golang-migrate/migrate/v4/GETTING_STARTED.md @@ -0,0 +1,43 @@ +# Getting started +Before you start, you should understand the concept of forward/up and reverse/down database migrations. + +Configure a database for your application.

These migrations can be provided +by any one of the supported [migration sources](./README.md#migration-sources). + +The ordering and direction of the migration files is determined by the filenames +used for them. `migrate` expects the filenames of migrations to have the format: + + {version}_{title}.up.{extension} + {version}_{title}.down.{extension} + +The `title` of each migration is unused, and is only for readability. Similarly, +the `extension` of the migration files is not checked by the library, and should +be an appropriate format for the database in use (`.sql` for SQL variants, for +instance). + +Versions of migrations may be represented as any 64 bit unsigned integer. +All migrations are applied upward in order of increasing version number, and +downward by decreasing version number. + +Common versioning schemes include incrementing integers: + + 1_initialize_schema.down.sql + 1_initialize_schema.up.sql + 2_add_table.down.sql + 2_add_table.up.sql + ... + +Or timestamps at an appropriate resolution: + + 1500360784_initialize_schema.down.sql + 1500360784_initialize_schema.up.sql + 1500445949_add_table.down.sql + 1500445949_add_table.up.sql + ... + +But any scheme resulting in distinct, incrementing integers as versions is valid. + +It is suggested that the version number of corresponding `up` and `down` migration +files be equivalent for clarity, but they are allowed to differ so long as the +relative ordering of the migrations is preserved. + +The migration files are permitted to be "empty", in the event that a migration +is a no-op or is irreversible. It is recommended to still include both migration +files by making the whole migration file consist of a comment. +If your database does not support comments, then deleting the migration file will also work. +Note, an actual empty file (e.g. a 0 byte file) may cause issues with your database since migrate +will attempt to run an empty query. In this case, deleting the migration file will also work. +For the rational of this behavior see: +[#244 (comment)](https://github.com/golang-migrate/migrate/issues/244#issuecomment-510758270) + +## Migration Content Format + +The format of the migration files themselves varies between database systems. +Different databases have different semantics around schema changes and when and +how they are allowed to occur +(for instance, [if schema changes can occur within a transaction](https://wiki.postgresql.org/wiki/Transactional_DDL_in_PostgreSQL:_A_Competitive_Analysis)). + +As such, the `migrate` library has little to no checking around the format of +migration sources. The migration files are generally processed directly by the +drivers as raw operations. + +## Reversibility of Migrations + +Best practice for writing schema migration is that all migrations should be +reversible. It should in theory be possible for run migrations down and back up +through any and all versions with the state being fully cleaned and recreated +by doing so. + +By adhering to this recommended practice, development and deployment of new code +is cleaner and easier (cleaning database state for a new feature should be as +easy as migrating down to a prior version, and back up to the latest). + +As opposed to some other migration libraries, `migrate` represents up and down +migrations as separate files. This prevents any non-standard file syntax from +being introduced which may result in unintended behavior or errors, depending +on what database is processing the file. + +While it is technically possible for an up or down migration to exist on its own +without an equivalently versioned counterpart, it is strongly recommended to +always include a down migration which cleans up the state of the corresponding +up migration. diff --git a/vendor/github.com/golang-migrate/migrate/v4/Makefile b/vendor/github.com/golang-migrate/migrate/v4/Makefile new file mode 100644 index 000000000..a0cd24afe --- /dev/null +++ b/vendor/github.com/golang-migrate/migrate/v4/Makefile @@ -0,0 +1,105 @@ +SOURCE ?= file go_bindata github github_ee aws_s3 google_cloud_storage godoc_vfs gitlab +DATABASE ?= postgres mysql redshift cassandra spanner cockroachdb clickhouse mongodb sqlserver +VERSION ?= $(shell git describe --tags 2>/dev/null | cut -c 2-) +TEST_FLAGS ?= +REPO_OWNER ?= $(shell cd .. && basename "$$(pwd)") +COVERAGE_DIR ?= .coverage + + +build-cli: clean + -mkdir ./cli/build + cd ./cmd/migrate && CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -o ../../cli/build/migrate.linux-amd64 -ldflags='-X main.Version=$(VERSION) -extldflags "-static"' -tags '$(DATABASE) $(SOURCE)' . + cd ./cmd/migrate && CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build -a -o ../../cli/build/migrate.darwin-amd64 -ldflags='-X main.Version=$(VERSION) -extldflags "-static"' -tags '$(DATABASE) $(SOURCE)' . + cd ./cmd/migrate && CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build -a -o ../../cli/build/migrate.windows-amd64.exe -ldflags='-X main.Version=$(VERSION) -extldflags "-static"' -tags '$(DATABASE) $(SOURCE)' . + cd ./cli/build && find . -name 'migrate*' | xargs -I{} tar czf {}.tar.gz {} + cd ./cli/build && shasum -a 256 * > sha256sum.txt + cat ./cli/build/sha256sum.txt + + +clean: + -rm -r ./cli/build + + +test-short: + make test-with-flags --ignore-errors TEST_FLAGS='-short' + + +test: + @-rm -r $(COVERAGE_DIR) + @mkdir $(COVERAGE_DIR) + make test-with-flags TEST_FLAGS='-v -race -covermode atomic -coverprofile $$(COVERAGE_DIR)/combined.txt -bench=. -benchmem -timeout 20m' + + +test-with-flags: + @echo SOURCE: $(SOURCE) + @echo DATABASE: $(DATABASE) + + @go test $(TEST_FLAGS) ./... + + +kill-orphaned-docker-containers: + docker rm -f $(shell docker ps -aq --filter label=migrate_test) + + +html-coverage: + go tool cover -html=$(COVERAGE_DIR)/combined.txt + + +list-external-deps: + $(call external_deps,'.') + $(call external_deps,'./cli/...') + $(call external_deps,'./testing/...') + + $(foreach v, $(SOURCE), $(call external_deps,'./source/$(v)/...')) + $(call external_deps,'./source/testing/...') + $(call external_deps,'./source/stub/...') + + $(foreach v, $(DATABASE), $(call external_deps,'./database/$(v)/...')) + $(call external_deps,'./database/testing/...') + $(call external_deps,'./database/stub/...') + + +restore-import-paths: + find . -name '*.go' -type f -execdir sed -i '' s%\"github.com/$(REPO_OWNER)/migrate%\"github.com/mattes/migrate%g '{}' \; + + +rewrite-import-paths: + find . -name '*.go' -type f -execdir sed -i '' s%\"github.com/mattes/migrate%\"github.com/$(REPO_OWNER)/migrate%g '{}' \; + + +# example: fswatch -0 --exclude .godoc.pid --event Updated . | xargs -0 -n1 -I{} make docs +docs: + -make kill-docs + nohup godoc -play -http=127.0.0.1:6064 /dev/null 2>&1 & echo $$!

The problem +with this pattern is that you completely lose the original `error` structure. + +Arguably the _correct_ approach is that you should make a custom structure +implementing the `error` interface, and have the original error as a field +on that structure, such [as this example](http://golang.org/pkg/os/#PathError). +This is a good approach, but you have to know the entire chain of possible +rewrapping that happens, when you might just care about one. + +`errwrap` formalizes this pattern (it doesn't matter what approach you use +above) by giving a single interface for wrapping errors, checking if a specific +error is wrapped, and extracting that error. + +## Installation and Docs + +Install using `go get github.com/hashicorp/errwrap`. + +Full documentation is available at +http://godoc.org/github.com/hashicorp/errwrap + +## Usage + +#### Basic Usage + +Below is a very basic example of its usage: + +```go +// A function that always returns an error, but wraps it, like a real +// function might. +func tryOpen() error { + _, err := os.Open("/i/dont/exist") + if err != nil { + return errwrap.Wrapf("Doesn't exist: {{err}}", err) + } + + return nil +} + +func main() { + err := tryOpen() + + // We can use the Contains helpers to check if an error contains + // another error.

This would return nil if that specific error doesn't + // exist. + perr := errwrap.GetType(err, new(os.PathError)) +} +``` + +#### Custom Types + +If you're already making custom types that properly wrap errors, then +you can get all the functionality of `errwraps.Contains` and such by +implementing the `Wrapper` interface with just one function. Example: + +```go +type AppError { + Code ErrorCode + Err error +} + +func (e *AppError) WrappedErrors() []error { + return []error{e.Err} +} +``` + +Now this works: + +```go +err := &AppError{Err: fmt.Errorf("an error")} +if errwrap.ContainsType(err, fmt.Errorf("")) { + // This will work! +} +``` diff --git a/vendor/github.com/hashicorp/errwrap/errwrap.go b/vendor/github.com/hashicorp/errwrap/errwrap.go new file mode 100644 index 000000000..a733bef18 --- /dev/null +++ b/vendor/github.com/hashicorp/errwrap/errwrap.go @@ -0,0 +1,169 @@ +// Package errwrap implements methods to formalize error wrapping in Go. +// +// All of the top-level functions that take an `error` are built to be able +// to take any error, not just wrapped errors.

This ensures that the compiled binaries are portable and do not require around the migrations themselves along with the binary. Also updated the makefile to pull the go-bindata file and generate the `migration.go` file as part of `make build` --- Makefile | 8 +- cmd/configmap-server/main.go | 2 +- cmd/initializer/main.go | 2
