TODO.txt

v1.0
- colorpicker default listed colors revised (high contrast)
- bubbles' content revised/customizable
- journey log created, content revised
- consider tracks from various sources (SkyDemon, ForeFlight, GeoTracker, Garmin5)
- consider place-name based waypoint selection (based on a public database)
- some edit messages go to the same session_id's (realtime showing of changes if app open in two windows)

v0.3
+ multiple maps (from multiple countries, 1 additional country introduced)
+ bugfix: server could not start when no map was downloaded
+ limit tile download to 3 simultaneous
+ bugfix: always left-top tile was drawn first
+ include tile png generation in the build process (commented out, because Koyeb build times out)
+ tile cache pre-generation included in main server as a background process
+ bugfix: invalid-step-value error was sent regardless of error condition
+ separate VFRFunctionRoute class from the rest (~geometry.py)
+ limit the session connections based on number of open sessions & visual feedback if no connection available
+ server setup moved into `api` package
+ waypoints/constraint points lon-lat editable (in degrees/minutes/seconds and decimal format) in step1
+ points lon-lat editable all steps, addable by lon-lat
+ best linear approximation for GPX export
+ optimize memory consumption during final image generation
+ limit the area of interest based on expected memory consumption
+ changed use_sample_weather setting to always_use_real_weather (can be set if annotation edit page also uses)
+ switch from WebSocket to Socket.IO for its fallback to long-polling capabilities
+ published routes on postgres (to not lose on redeploy)
+ review socket.io handlers for async friendlyness
+ solve all linting problems
+ bugfix: tracks with same name breaks program logic + can't add twice the same file before refreshing page
+ bugfix: annotations are also refreshed when clicking a non-point
/ bugfix: add annotation point -> server exception (not in list) - can't reproduce
+ bugfix: leg definition changes to dotted lines while changing function
+ bugfix: session limit handling was a mess + start connection with polling
/ bugfix: on server exception, frontend keeps the progress indication - can't reproduce
+ close route button on step 6
+ bugfix: waypoint update state fix for annotations
+ bugfix: added square root as known function + latex conversion error handling fixes
+ bugfix: increase socket.io frame limit
+ solved linting issues came up since last review
+ object storage for map tiles and pdfs to avoid regeneration on container sleep
+ add vor/radial/dme format as waypoints
+ set dme arc x-values
+ default/loaded route's date modified on load if earlier than now
+ non-closed routes
+ can add airports by name
+ can disable server side local caching


v0.2
+ landing page
+ memory optimizations for low-res map
  + separate data sending from image sending
  + instead of contextmanager, be explicit about figure release
  + instead of plotting the map, use Pillow based manipulation
  + send images as binary through socket (centralize receiving in frontend)
  + send smaller tiles through websocket (this will also be good for progress display)
+ bugfix: LOW_DPI dependent tiles coordinates
+ no contextmanagers for figures
+ session management: time to live for sessions in the session store (api/routes.py:_vfrroutes)
+ session management: session_id is always sent in http and ws requests (retreived from localStorage)
+ the same memory optimizations for waypoints map
+ bugfix: the last tiles (in a row, in a column) are stretched (of course: they are smaller, but this
  is not considered)
+ the same memory optimizations for legs map
+ the same memory optimizations for annotations map
+ the same memory optimizations for tracks map
+ bugfix: LOW_DPI dependent VFRPoint transformations
+ bugfix: HIGH_DPI dependent VFRPoint transformations
+ memory optimizations for final image generation
  + binary transfer of final documents (PNG, DOCX)
  + introduced a resolution for this drawing (DOC_DPI)
  + background not drawn with matplotlib, but composited with PIL
  + background done with tiling (for tiles: bg_img.paste(get_tile(0, 0), (0, 0)))
+ cacheable tiles
  + overlay rendered into svg, frontend has 3 layers: map (canvas, tiles),
    server_overlay (svg), client_overlay (canvas); figure released immediately by
    SVGRenderer (this way map tiles will be uniform)
  + high resolution tiles are rendered according to fixed grid (this is
    needed for uniform map tiles)
  + frontend clips on the side to avoid larger maps shown than requested
  + bugfix: doc generation was not updated to fixed grid
+ tile cache
  + server caches to disk and checks before creating
  + change to http get for tiles, frontend uses http cache for tiles
+ bugfix: map download needed to be put at an earlier stage
+ bugfix: api endpoint rewrote by angular to /frontend/api/..., changed to absolute url
+ mapedit: moving amount is not decreasing when scaled
+ annotations: during edit, no realtime data is downloaded, only during final generation
+ sample route is loaded from file instead of generating it in code (also tracks are included)
+ annotations: text overlay refreshed automatically after every edit (1-1,5s delay is tolerable)
  and default to not show (wrongly) estimated bubbles
+ annotations: text is english + bugfix of prev commit
+ annotations: more precise bubble estimation
+ annotations: bubbles can be moved with mouse
+ add tooltips to buttons, no tooltip for app-header
+ remove unneccessary info (XY in map info panel)
+ double-click instead of middle button
+ mobile friendly: touch controls
+ bugfix: multiple constraint points, not editable?
+ calculation of final map size: area of interest never decreased, but
  increased if some function point would go outside
+ bugfix: extent calculation directly after load (matrix and function does not exist yet)
+ save to cloud
+ save to cloud sanitizes file name, checks for max published routes
+ bugfix: edge case no waypoints -> extent calculation crashed + filename sanitization update
+ mobile friendly: responsive action pages (landing, step0, step6)
+ bugfix: window resize caused zoom change
+ bugfix: edit boxes not recreated on change (navigating with tab was impossible)
+ mobile friendly: responsive map page in step2
+ mobile friendly: responsive map page in step1
+ mobile friendly: responsive map page in step3
+ first attempt to render 'function_range' correctly
+ fullscreen button in header
+ mobile friendly: steps 1-3 correctly handles portrait/landscape instead of screen width
+ mobile friendly: responsive map pages (step4)
+ mobile friendly: responsive map pages (step5)
+ fullscreen size fixed (tables were over the screen because of the url-bar-scroll-needed hack)
+ if was zoomed-to-all before resize, keep this feature after (instead of keeping zoom level)
+ session management
  + caching of states per session to disk periodically, load it on startup
  + if there is an open route on server, in step0 we can continue with that
  + each communication in a session raises it's expiry date
+ communication & its visual feedback
  + give visual feedback if no route is open on the server for the current session
  + visual feedback on each page if no open route on server
  + progress indication while waiting for server
  + visual feedback if error between steps (or in any communication)
+ tile download moved out from drawing loop
+ bugfix: first & last of leg's points and annotations were deletable
+ bugfix: step3 icon buttons were misrendered
+ bugfix: step1 did not dim invalid lon-lat values
+ route editing
  + speed & name is modifiable in step 6
  + order constraint points by func_x automatically
  + bugfix: readonly mathedit does not show formula
  + edit "function_range" on leg page (maybe it could be automatic?)
+ proper error when no wind forecast

+ transition to LEG definition step (waypoints to legs conversion, 
  considering existing legs)
+ stepping refactor
+ legs
  + transferring leg definitions to frontend
  + transferring leg function matrices to frontend
  + drawing leg overlays (with hardcoded linear function)
  + editing leg functions

  + vfr format save-load
  + change dof before generation
+ auto reconnect websocket (or change to socket.io)
+ deploy

  + websocket path adjusted to deployed one
  + high and low resolution set from environment variable (instead if hardcoded)
