042cac5fed* Improve install code to avoid low-level mistakes. If a user tries to do a re-install in a Gitea database, they gets a warning and double check. When Gitea runs, it never create empty app.ini automatically. Also some small (related) refactoring: * Refactor db.InitEngine related logic make it more clean (especially for the install code) * Move some i18n strings out from setting.go to make the setting.go can be easily maintained. * Show errors in CLI code if an incorrect app.ini is used. * APP_DATA_PATH is created when installing, and checked when starting (no empty directory is created any more).

// FIXME: There are too many calls to MkdirAll in old code. It is incorrect.
|
|
// For example, if someDir=/mnt/vol1/gitea-home/data, if the mount point /mnt/vol1 is not mounted when Gitea runs,
|
|
// then gitea will make new empty directories in /mnt/vol1, all are stored in the root filesystem.
|
|
// The correct behavior should be: creating parent directories is end users' duty. We only create sub-directories in existing parent directories.
|
|
// For quickstart, the parent directories should be created automatically for first startup (eg: a flag or a check of INSTALL_LOCK).
|
|
// Now we can take the first step to do correctly (using Mkdir) in other packages, and prepare the AppDataPath here, then make a refactor in future.
