(Feature request) ETAPI interface to get note content hash #4005

Open mm21 opened 1 year ago

Describe feature

Hi,

I'm building a tool to synchronize Trilium with a locally-maintained note tree, and it would really help to be able to get the hash of a note's current content. That way someone could check if the local file is already in sync with Trilium, without downloading the content or just blindly updating it every time.

This will become more important later as I intend to build a photo manager and efficiently track thousands of photos using Trilium. (Imagine syncing a folder of photos and being able to tag people/places just by setting a relation, with labels automatically populated by the photo's exif data. But I digress...)

I see the hash is already computed in BNote.setContent(), can that be readily accessed by ETAPI? Base64-encoded SHA1 is perfect.

Thanks for considering!

I've added "blobId" to the ETAPI interface in 0.61. For note types which are "copy on write", this effectively represents a content hash. It might not cover your needs completely, as for some notes (text notes), this doesn't change.

Thanks, this will work for binary notes which was my main concern. To accommodate text notes, can forceCold be added as a parameter to putNoteContentById? Then when I set content during a sync, I'll always pass forceCold to generate the blobId for the next sync.

Actually, your comment got me thinking and I reworked this to behave uniformly - blobId will be effectively a content hash for all types of notes.

Nice, thanks a lot!

re: https://github.com/zadam/trilium/issues/4005#issuecomment-1581558060 is there remaining work to finish this off? if so please specify what's left and maybe someone will pick it up (perhaps even me if I can come up to speed).
