From bc48628839c656e7136540d25ad706cee4816944 Mon Sep 17 00:00:00 2001 From: Reto Brunner Date: Sun, 13 Sep 2020 10:42:40 +0200 Subject: [PATCH] maildir: track the recent flag correctly In the maildir worker we manually need to track the Recent flag in order for the notification command etc to work. Push that responsibility to the container, we must make sure to manually add the flag though if one grabs the message info. --- worker/maildir/container.go | 40 ++++++++++++++++++++++++-------- worker/maildir/worker.go | 46 +++++++++++++++++++------------------ 2 files changed, 55 insertions(+), 31 deletions(-) diff --git a/worker/maildir/container.go b/worker/maildir/container.go index 14815c9..1bdc4e7 100644 --- a/worker/maildir/container.go +++ b/worker/maildir/container.go @@ -15,9 +15,10 @@ import ( // A Container is a directory which contains other directories which adhere to // the Maildir spec type Container struct { - dir string - log *log.Logger - uids *uidstore.Store + dir string + log *log.Logger + uids *uidstore.Store + recentUIDS map[uint32]struct{} // used to set the recent flag } // NewContainer creates a new container at the specified directory @@ -34,7 +35,8 @@ func NewContainer(dir string, l *log.Logger) (*Container, error) { if !s.IsDir() { return nil, fmt.Errorf("Given maildir '%s' not a directory", dir) } - return &Container{dir: dir, uids: uidstore.NewStore(), log: l}, nil + return &Container{dir: dir, uids: uidstore.NewStore(), log: l, + recentUIDS: make(map[uint32]struct{})}, nil } // ListFolders returns a list of maildir folders in the container @@ -72,17 +74,26 @@ func (c *Container) ListFolders() ([]string, error) { return folders, err } +// SyncNewMail adds emails from new to cur, tracking them +func (c *Container) SyncNewMail(dir maildir.Dir) error { + keys, err := dir.Unseen() + if err != nil { + return err + } + for _, key := range keys { + uid := c.uids.GetOrInsert(key) + c.recentUIDS[uid] = struct{}{} + } + return nil +} + // OpenDirectory opens an existing maildir in the container by name, moves new // messages into cur, and registers the new keys in the UIDStore. func (c *Container) OpenDirectory(name string) (maildir.Dir, error) { dir := c.Dir(name) - keys, err := dir.Unseen() - if err != nil { + if err := c.SyncNewMail(dir);
