To avoid duplicated load of the same data in an HTTP request, we can set
a context cache to do that. i.e. Some pages may load a user from a
database with the same id in different areas on the same page. But the
code is hidden in two different deep logic. How should we share the
user? As a result of this PR, now if both entry functions accept
`context.Context` as the first parameter and we just need to refactor
`GetUserByID` to reuse the user from the context cache. Then it will not
be loaded twice on an HTTP request.
But of course, sometimes we would like to reload an object from the
database, that's why `RemoveContextData` is also exposed.
The core context cache is here. It defines a new context
```go
type cacheContext struct {
ctx context.Context
data map[any]map[any]any
lock sync.RWMutex
}
var cacheContextKey = struct{}{}
func WithCacheContext(ctx context.Context) context.Context {
return context.WithValue(ctx, cacheContextKey, &cacheContext{
ctx: ctx,
data: make(map[any]map[any]any),
})
}
```
Then you can use the below 4 methods to read/write/del the data within
the same context.
```go
func GetContextData(ctx context.Context, tp, key any) any
func SetContextData(ctx context.Context, tp, key, value any)
func RemoveContextData(ctx context.Context, tp, key any)
func GetWithContextCache[T any](ctx context.Context, cacheGroupKey string, cacheTargetID any, f func() (T, error)) (T, error)
```
Then let's take a look at how `system.GetString` implement it.
```go
func GetSetting(ctx context.Context, key string) (string, error) {
return cache.GetWithContextCache(ctx, contextCacheKey, key, func() (string, error) {
return cache.GetString(genSettingCacheKey(key), func() (string, error) {
res, err := GetSettingNoCache(ctx, key)
if err != nil {
return "", err
}
return res.SettingValue, nil
})
})
}
```
First, it will check if context data include the setting object with the
key. If not, it will query from the global cache which may be memory or
a Redis cache. If not, it will get the object from the database. In the
end, if the object gets from the global cache or database, it will be
set into the context cache.
An object stored in the context cache will only be destroyed after the
context disappeared.

Integration tests
Integration tests can be run with make commands for the appropriate backends, namely:
make test-sqlite
make test-pgsql
make test-mysql
make test-mysql8
make test-mssql
Make sure to perform a clean build before running tests:
make clean build
Run all tests via local drone
drone exec --local --build-event "pull_request"
Run sqlite integration tests
Start tests
make test-sqlite
Run MySQL integration tests
Setup a MySQL database inside docker
docker run -e "MYSQL_DATABASE=test" -e "MYSQL_ALLOW_EMPTY_PASSWORD=yes" -p 3306:3306 --rm --name mysql mysql:latest #(just ctrl-c to stop db and clean the container)
docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" --rm --name elasticsearch elasticsearch:7.6.0 #(in a second terminal, just ctrl-c to stop db and clean the container)
Start tests based on the database container
TEST_MYSQL_HOST=localhost:3306 TEST_MYSQL_DBNAME=test TEST_MYSQL_USERNAME=root TEST_MYSQL_PASSWORD='' make test-mysql
Run pgsql integration tests
Setup a pgsql database inside docker
docker run -e "POSTGRES_DB=test" -p 5432:5432 --rm --name pgsql postgres:latest #(just ctrl-c to stop db and clean the container)
Start tests based on the database container
TEST_PGSQL_HOST=localhost:5432 TEST_PGSQL_DBNAME=test TEST_PGSQL_USERNAME=postgres TEST_PGSQL_PASSWORD=postgres make test-pgsql
Run mssql integration tests
Setup a mssql database inside docker
docker run -e "ACCEPT_EULA=Y" -e "MSSQL_PID=Standard" -e "SA_PASSWORD=MwantsaSecurePassword1" -p 1433:1433 --rm --name mssql microsoft/mssql-server-linux:latest #(just ctrl-c to stop db and clean the container)
Start tests based on the database container
TEST_MSSQL_HOST=localhost:1433 TEST_MSSQL_DBNAME=gitea_test TEST_MSSQL_USERNAME=sa TEST_MSSQL_PASSWORD=MwantsaSecurePassword1 make test-mssql
Running individual tests
Example command to run GPG test:
For SQLite:
make test-sqlite#GPG
For other databases(replace mssql to mysql, mysql8 or pgsql):
TEST_MSSQL_HOST=localhost:1433 TEST_MSSQL_DBNAME=test TEST_MSSQL_USERNAME=sa TEST_MSSQL_PASSWORD=MwantsaSecurePassword1 make test-mssql#GPG
Setting timeouts for declaring long-tests and long-flushes
We appreciate that some testing machines may not be very powerful and the default timeouts for declaring a slow test or a slow clean-up flush may not be appropriate.
You can either:
- Within the test ini file set the following section:
[integration-tests]
SLOW_TEST = 10s ; 10s is the default value
SLOW_FLUSH = 5S ; 5s is the default value
- Set the following environment variables:
GITEA_SLOW_TEST_TIME="10s" GITEA_SLOW_FLUSH_TIME="5s" make test-sqlite
