Move state tracking into the puller/scanner objects. This is a first
step towards resolving #1391.
Rename Puller and Scanner to roFolder and rwFolder as they have more
duties than just pulling and scanning, and don't need to be exported.
Replace the current mix of UpperCamelCase und lowerCamelCase with
consistent lowerCamelCase keys for the JSON API. Also adapt the frontend
so it works with the changed API.
Attention: this will break existing consumers of the API.
Integers are for numbers, enabling arithmetic like subtractions and for
loops without getting shot in the foot. Unsigneds are for bitfields.
- "int" for numbers that will always be laughably smaller than four
billion, and where we don't care about the serialization format.
- "int32" for numbers that will always be laughably smaller than four
billion, and will be serialized to four bytes.
- "int64" for numbers that may approach four billion or will be
serialized to eight bytes.
- "uint32" and "uint64" for bitfields, depending on required number of
bits and serialization format. Likewise "uint8" and "uint16", although
rare in this project since they don't exist in XDR.
- "int8", "int16" and plain "uint" are almost never useful.
Request to terminate currently ongoing downloads and jump to the bumped file
incoming in 3, 2, 1.
Also, has a slightly strange effect where we pop a job off the queue, but
the copyChannel is still busy and blocks, though it gets moved to the
progress slice in the jobqueue, and looks like it's in progress which it isn't
as it's waiting to be picked up from the copyChan.
As a result, the progress emitter doesn't register on the task, and hence the file
doesn't have a progress bar, but cannot be replaced by a bump.
I guess I can fix progress bar issue by moving the progressEmiter.Register just
before passing the file to the copyChan, but then we are back to the initial
problem of a file with a progress bar, but no progress happening as it's stuck
on write to copyChan
I checked if there is a way to check for channel writeability (before popping)
but got struck by lightning just for bringing the idea up in #go-nuts.
My ideal scenario would be to check if copyChan is writeable, pop job from the
queue and shove it down handleFile. This way jobs would stay in the queue while
they cannot be handled, meaning that the `Bump` could bring your file up higher.
With this change we accept updates for ignored files from other devices,
and check the ignore patterns at pull time. When we detect that the
ignore patterns have changed we do a full check of files that we might
now need to pull.
This uses persistent Matcher objects that can reload their content and
provide a hash string that can be used to check if it's changed. The
cache is local to each Matcher object instead of kept globally.
