Rewrite logger system (#24726)
## ⚠️ Breaking

The `log.<mode>.<logger>` style config has been dropped. If you used it,
please check the new config manual & app.example.ini to make your
instance output logs as expected.

Although many legacy options still work, it's encouraged to upgrade to
the new options.

The SMTP logger is deleted because SMTP is not suitable to collect logs.

If you have manually configured Gitea log options, please confirm the
logger system works as expected after upgrading.

## Description

Close #12082 and maybe more log-related issues, resolve some related
FIXMEs in old code (which seems unfixable before)

Just like rewriting queue #24505 : make code maintainable, clear legacy
bugs, and add the ability to support more writers (eg: JSON, structured
log)

There is a new document (with examples): `logging-config.en-us.md`

This PR is safer than the queue rewriting, because it's just for
logging, it won't break other logic.

## The old problems

The logging system is quite old and difficult to maintain:
* Unclear concepts: Logger, NamedLogger, MultiChannelledLogger,
SubLogger, EventLogger, WriterLogger etc
* Some code is diffuclt to konw whether it is right:
`log.DelNamedLogger("console")` vs `log.DelNamedLogger(log.DEFAULT)` vs
`log.DelLogger("console")`
* The old system heavily depends on ini config system, it's difficult to
create new logger for different purpose, and it's very fragile.
* The "color" trick is difficult to use and read, many colors are
unnecessary, and in the future structured log could help
* It's difficult to add other log formats, eg: JSON format
* The log outputer doesn't have full control of its goroutine, it's
difficult to make outputer have advanced behaviors
* The logs could be lost in some cases: eg: no Fatal error when using
CLI.
* Config options are passed by JSON, which is quite fragile.
* INI package makes the KEY in `[log]` section visible in `[log.sub1]`
and `[log.sub1.subA]`, this behavior is quite fragile and would cause
more unclear problems, and there is no strong requirement to support
`log.<mode>.<logger>` syntax.


## The new design

See `logger.go` for documents.

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 tests via local act_runner

Run all jobs

act_runner exec -W ./.github/workflows/pull-db-tests.yml --event=pull_request --default-actions-url="https://github.com" -i catthehacker/ubuntu:runner-latest

Warning: This file defines many jobs, so it will be resource-intensive and therefor not recommended.

Run single job

act_runner exec -W ./.github/workflows/pull-db-tests.yml --event=pull_request --default-actions-url="https://github.com" -i catthehacker/ubuntu:runner-latest -j <job_name>

You can list all job names via:

act_runner exec -W ./.github/workflows/pull-db-tests.yml --event=pull_request --default-actions-url="https://github.com" -i catthehacker/ubuntu:runner-latest -l

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
