## te doen voor werkend prototype (beta testers)
|
|
- (testen) server logging
|
|
- (testen/verder implementeren) stopknop
|
|
- volgorde chunks (en vaker voorkomen?): elke chunk naar los bestand en op het laatst samenvoegen
|
|
- (client) autopreheat wanneer er een printer aanwezig is
|
|
- (fw) temp gcode pad veranderen naar device-specifiek (i.e. /tmp/UltiFi/ttyACM?/combined.gc)
|
|
- (fw) bij (her)initialisatie printer altijd alle state weggooien (i.e. /dev/UtliFi/ttyACM?)
|
|
- client feedback
|
|
* voor ontwikkeling: debugoverlay
|
|
* vaker op 'print' drukken moet niet kunnen (knop disablen en op basis van polling (isPrinting?) status up-to-date houden)
|
|
-> maar! de firmware moet geen nieuwe printopdrachten accepteren wanneer er al een print bezig is
|
|
* temperatuurindicatie (alleen wanneer temperatuuruitlezing via api mogelijk is) -> dus ook indicatie van draaiende printserver
|
|
- (misschien?) verticale shape aanpassen
|
|
- preheaten voor het starten van een print
|
|
* (fw) wachten op targettemperatuur - 20 graden (hoe om te gaan met afkoelen?)
|
|
* (client) in config bij temperatuurinstelling: opmerking dat de printer gaat printen vanaf lagere temperatuur (bv. -20)
|
|
|
|
## te den voor final release
|
|
- start/end-codes configureerbaar maken (via los endpoint) (duplicate)
|
|
- printerlijst opvragen
|
|
* data: per printer: {id, path, type}
|
|
- gcode: printer busy rapporteren vanaf moment dat gcode wordt verzameld, niet pas bij begin printen (of gcode verzamelen per remote host?)
|
|
- op wiki over openwrt/osx svn checkout veranderen naar git clone
|
|
- image met alles erin
|
|
* in postinst op kastje: ook wifibox start doen (enable doet dat niet) (ook voor ultifi)
|
|
* firewall net wordt nog niet aangemaakt in 'Y'-mode
|
|
- nadenken over loggen (procedure voor testers hoe ze problemen kunnen rapporteren zodat wij ze kunnen reproduceren)
|
|
* verzamelen+zippen van logread output (of uci system.@system[0].log_file?) + /tmp/wifibox.conf + printserver log
|
|
- na /network/disassociate is wifi uitgeschakeld -> kan geen macadres opvragen -> openap bv. 2x nodig om weer goed macadres te vinden
|
|
- client: netwerkkeuze toevoegen?
|
|
- herstart van uhttpd en reboot uitstellen tot na sturen van response (closure queue in response.lua)
|
|
- consistentie REST API
|
|
- code documenteren
|
|
- codedocs uitwerken naar apidocs
|
|
- optie voor loggen toevoegen aan printmanager
|
|
- AP en client tegelijk (VAP / multi-ssid?)
|
|
* toegang altijd via AP, clientmode alleen voor updaten en internet ook via kastje (dan moet wel de portalmodus uit)
|
|
* dns forward: list 'dhcp_option' '6,10.0.0.1,192.168.178.1' (<http://wiki.openwrt.org/doc/howto/dhcp.dnsmasq#configuring.dnsmasq.to.broadcast.external.dns.server.information>)
|
|
- auto-update (zowel package als geheel image; <- kijken hoe luci dat doet)
|
|
- serieel:
|
|
* 115k2? -> Peter zei iets over instabiele connectie op 250k?
|
|
* fallback lijkt niet te werken (zelfde probleem als bij poort opnieuw openen?)
|
|
* mss helpt arduino reset triggeren om port opnieuw te kunnen openen?
|
|
* 3e manier baudrate zetten? <http://stackoverflow.com/questions/4968529/how-to-set-baud-rate-to-307200-on-linux>
|
|
- initscript testen (lijkt vaker dan eens te worden uitgevoerd)
|
|
- printerExists: ook nagaan of basispad ultifi bestaat?
|
|
|
|
|
|
## OOK MEE BEZIG
|
|
- in AP mode, things like 'somewhere.org/asdsfd' still results in 'Not found'
|
|
- behalve /dev/ttyACM* kan het voor FTDI dus ook /dev/ttyUSB* zijn
|
|
- config API: anders inrichten (misschien toch 1 key per keer instellen zodat response 'fail' kan zijn?)
|
|
|
|
- auto-update
|
|
- source-url in Makefile aanpassen (type aanpassen naar git en dan direct naar github repo)
|
|
- toevoegen aan /etc/opkg.conf via files in image: `src/gz wifibox http://doodle3d.com/static/wifibox-packages`
|
|
- of lokaal: `src/gz wifibox file:///tmp/wifibox-packages`
|
|
- (info) feed update-script: <wifibox_git_root>/extra/create-packages-dir.sh
|
|
uitvoeren vanuit pad waar wifibox_packages terecht moet komen (bv. ~/Sites)
|
|
- (info) package-url: <http://doodle3d.com/static/wifibox/packages>
|
|
- (info) image-url: <http://doodle3d.com/static/wifibox/images>
|
|
- later: printerprofielen
|
|
|
|
- API:
|
|
api/info/currentVersion
|
|
api/info/latestVersion [beta=true]
|
|
api/system/update
|
|
api/system/flash
|
|
* wat als wij een verkeerd package releasen waardoor de API niet meer werkt?
|

- (ref) <http://wiki.openwrt.org/doc/techref/opkg>
|
|
- (ref) <http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/>
|
|
- waar moeten debugvlaggen etc naartoe? (run_flags.lua?)
|
|
- in package postinst: hostname van kastje instellen op wifibox (met mac?)
|
|
|
|
- tijdens openwrt make:
|
|
'* satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-ath9k-common:
|
|
'* kmod-crypto-hash *
|
|
- wiki bijwerken (links, structuur, API)
|
|
- ook in wiki, luadoc installeren:
|
|
* !! (beter vervangen door?) <http://stevedonovan.github.io/ldoc/topics/doc.md.html>
|
|
* ongeveer volgens <http://www.hobsie.com/mark/archives/33>, maar! :
|
|
* luasocket apart installeren met `sudo luarocks install https://raw.github.com/diegonehab/luasocket/master/luasocket-scm-0.rockspec`
|
|
- Code documenteren <http://keplerproject.github.io/luadoc/>
|
|
- Lua programmeerstijl? (enkele quotes gebruiken behalve voor i18n)
|
|
- zoals het nu werkt wordt het lastig om een hiërarchische api te ondersteunen zoals dit: <http://www.restapitutorial.com/lessons/restfulresourcenaming.html>
|
|
- uhttpd ondersteunt geen PUT en DELETE, wel status codes. Beschrijving CGI-antwoorden: <http://docstore.mik.ua/orelly/linux/cgi/ch03_03.htm>
|
|
- voor captive portal: cgi 'Location' header voor redirect naar goede url?
|
|
|
|
- http statuscodes <https://blog.apigee.com/detail/restful_api_design_what_about_errors>; met relevante link in antwoord (meer: <https://blog.apigee.com/taglist/restful>)
|
|
- proposed status handling in response.lua:
|
|
fucntion setStatus(code, <msg>) -> sets http status+dfl msg and optional errmsg in data
|
|
|
|
# TODO (new functionality)
|
|
- fix init script handling as described here: http://wiki.openwrt.org/doc/devel/packages#packaging.a.service
|
|
- implement (automated) test code where possible
|
|
* in 'test' dir next to 'src', with API tests under 'test/www/'
|
|
* www tests check functionality of the test module
|
|
* www tests also provide an interface to run arbitrary get/post requests
|
|
* test path splitting as well
|
|
- document REST API
|
|
* fail/error difference: fail is a valid rq aka 'could not comply', while error is invalid rq _or_ system error
|
|
* modules/functions prefixed with '_' are for internal use
|
|
* rq IDs and endpoint information can be supplied (but it's probably not useful after all)
|
|
* list endpoints+args+CRUD type
|
|
* success/fail/error statuses are justified by drupal api
|
|
* unknown values (e.g. in network info) are either empty or unmentioned fields
|
|
- define a list of REST error codes to be more descriptive for clients (e.g. errortype=system/missing-arg/generic)
|
|
- steps to take regarding versioning/updating
|
|
* versioning scheme
|
|
* create feed location (e.g. www.doodle3d.com/firmware/packages) (see here: http://wiki.openwrt.org/doc/packages#third.party.packages)
|
|
* create opkg (already present in bin/ar71xx/packages as .ipk file)
|
|
* create listing info for package list (checksum, size, etc. ...is this inside the .ipk file?)
|
|
* find a way to add the feed url to opkg.conf (directly in files during image building?)
|
|
* determine how opkg decides what is 'upgradeable'
|
|
* at this point manual updating should be possible, now find out how to implement in lua (execve? or write a minimalistic binding to libopkg?)
|
|
* expose through info API and/or system API; also provide a way (future) to flash a new image
|
|
- generally, for configuration keys, it could be a good idea to use the concept of default values so it's always possible to return to a 'sane default config'
|
|
* use a uci wifibox config to store configuration and a uci wifibox-defaults config as fallback-lookup (which contains a complete default configuration)
|
|
* specify min/max/type/regex for each config key in separate lua file
|
|
* perhaps defaults should be specified together with min/max/type/regex
|
|
- dynamic AP name based on partial MAC (present in default config so it can be overridden and reverted again)
|
|
- require api functions which change state to be invoked as post request
|
|
* can this be modelled like java annotations or c function attributes?
|
|
* otherwise maybe pair each function with <func>_attribs = {…}?
|
|
- add API functions to test network connectivity in steps (any chance(e.g. ~ap)? ifup? hasip? resolve? ping?) to network or test
|
|
- handling requests which need a restart of uhttpd (e.g. network/openap) will probably respond with some kind of 'please check back in a few seconds' response
|
|
- add more config options to package, which should act as defaults for a config file on the system; candidates:
|
|
reconf.WWW_RENAME_NAME, wifihelper.{AP_ADDRESS, AP_NETMASK, (NET)}
|
|

# Ideas / issues to work out
|
|
- add system api module? for check-updates/do-update/etc
|
|
- licensing (also for hardware and firmware) + credits for external code and used ideas (<http://www.codinghorror.com/blog/2007/04/pick-a-license-any-license.html>)
|
|
- (this is an old todo item from network:available(), might still be relevant at some point)
|
|
extend netconf interface to support function arguments (as tables) so wifihelper functionality can be integrated
|
|
but how? idea: pass x_args={arg1="a",arg2="2342"} for component 'x'
|
|
or: allow alternative for x="y" --> x={action="y", arg1="a", arg2="2342"}
|
|
in any case, arguments should be put in a new table to pass to the function (since order is undefined it must be an assoc array)
|
|
- perhaps opkg+safeboot could be useful in the update mechanism?
|
|
- add config option to compile sources using luac _or_ add an option to minify the lua code
|
|
|
|

# Bugs
|
|
- (captive portal mode) https is not redirected
|
|
- (captive portal mode) .local domains are not redirected
|
|
- (captive portal mode) any urls with text after the root domain are not redirected
|
|
- using iwinfo with interface name 'radio0' yields very little 'info' output while wlan0 works fine.
|
|
However, sometimes wlan0 disappears (happened after trying to associate with non-existing network)...why?
|
|
- protect dump function against reference loops (see <http://lua-users.org/wiki/TableSerialization>, json also handles this well)
|
|
- relocatabilty of package (take root prefix into consideration everywhere)
|
|
- disabling all wireless networks breaks the current method of obtaining the mac address, thus openap must be called twice before it is properly set up
