[o] implement Engine#reply (Engine simply has to include ReceiverMixin

[o] Andrew's technique http://groups.google.com/group/openwferu-users/browse_thread/thread/c2aa4b53d1664d45/8523a1a5ee98fd71
[o] Avishai : LocalParticipant : repost dispatch message
[o] Rdoc Ruote::Engine.register_participant -> passing a block to a participant
and perhaps also on
http://ruote.rubyforge.org/implementing_participants.html (Avish)
[o] wrap workitem in process error ? for on_error consumption (thanks Oleg)
doing workitem.fields['__error__'] = [ fei, time, error_message ]
[o] HashStorage should emit 'init persist fail' messages as well !
[o] Oleg's idea about participant on_reply
http://groups.google.com/group/openwferu-users/browse_thread/thread/2e6a95708c10847b
on_reply should be done in the receive action, not in Receiver
thus, in the ParticipantExpression
[x] exp : step (jump to cursor tag ?) : there is already the jump expression
[x] auto-participant re-apply
[o] receiver should be OK with a storage or a context
[x] Avishai : Worker : hook for rejecting the dispatch message
[o] receiver / local participant : reply/forward/proceed/... mess : fix
[o] storage participant : accept string for fei
[o] => Ruote::FlowExpressionId.extract(x)
[o] fei : place engine id in fei.to_storage_id (and back)
[o] wait_for(:inactive) blocks until worker is inactive
[o] storage0.copy_to(storage1) / migrate_to as requested by Matt Nichols
[o] check if rufus-lru is still needed
[o] storage migration : eats all the memory :(
[x] remove dependency on rufus-scheduler
[o] engine.storage_participant
[o] engine.noisy = true shortcut
[o] (ft_27) set "v:mypart" => [ 'MyParticipant', {} ]
binding a participant on the fly (just for this process)
[o] participant timeout as an instance method
[o] engine.process_wfids (lighter than engine.processes)
[o] storage.get_many(x, y, :descending => true) ?
[o] storage_participant.query : use skip and limit
[o] engine.processes use skip and limit
[o] engine.errors use skip and limit
[o] ParticipantEntry is a bit brittle when editing engine.participant_list
[o] use blank slate for process definition
[o] lib/ruote/svc for treechecker, error_handler and co (tree_checker)
[o] part/template.rb, use Rufus::Json.pretty_encode
[o] storage.clear OR storage.purge! OR both (cf discussion with marc_lee) !!
[o] Nathan : throw error on ${ruby:...} when ruby_eval_allowed is not set
[o] engine.kill and engine.cancel should accept fei, fexp or wfid
[o] participant params['tags'] = [ a, b, c ] ? costly (x expressions to read)
but passing them in the workitem could be fun
field['__tags__'] ?
[x] use treetop for more complex "${f:x} AND ${f:y}" ?
(systems like Rails require it anyway)
NO : using ruby_parser instead
[o] TreeChecker : exclude_fvccall :at_exit
[o] _if '${f:x} == ${f:y} || ${f:x} == ${f:z}'
[x] beanstalk [as a] workqueue ?
[o] tree.to_xml (require builder ?)
[o] tree.to_ruby
[o] __command__ + tag (rewind that cursor there, not the current one)
[o] rewind 'x' where x is a tagname (command x)
[o] solve the ps#root_expression_for(fei) dilemma
[x] condition : "${f:x} [is] empty" / this one is hard
[o] when : add test for cancelling when child has been triggered / is running
[o] engine.ps(wfid)
[x] alias "when" to "whenever" ?
[x] alias "when" to "on" / "upon"
[o] alias "when" to "once" "once x == y do"
[o] condition : "${'x} [is] empty" since ${array} => "[]"
[x] simple worker hooks ? (as discussed with @hassox)
on_terminate... ? only works in the same process as the worker
only for tests...
[o] on_error => retry / pass
[o] workitem : #as_json and #from_json
since ruote depends on rufus-json...
[x] engine.on_error = 'participant_name' // 'subprocess_name'
done at : http://github.com/jmettraux/ruote/commit/50292d954ff877f1f6615022216f346a7001b483
`--> reverting that for now, too dangerous
[o] process_count and error_count ? (processes(:count => true))
[o] exp : case (is it necessary ?) (guards ?) (hard for ruote-fluo)
[o] exp : lose
[o] conditional : rprefix ! ${r:x} is perhaps sufficient
[o] implement kill_process! (kill_expression! ?)
[o] /!\ resurrect CI
[o] user3 :rif => "!wi.fields['approvers'].include?('user3')" : 'in' operator
"${customer} in [ 1, 2, 3 ]"
"${customer} in { 'x' => 1 }"
[o] rename 'parser' to 'reader'
[o] ft_42 : maybe require storage to output ids already sorted
[o] Participant#rtimeout(workitem=nil)
[o] alias concurrent-iterator to citerator
[o] like we have a default WaitLogger, why not have a default HistoryLogger ?
so that context.history always returns something...
the default history would be storage based but with LRU turned on
for the HashStorage one...
like WaitLogger only remembers 147 msgs...
[o] StorageHistory : add a method to list all wfids (for by_wfid)
[o] DefaultHistory : add a method to list all wfids (for by_wfid)
[x] issue with ruote-kit and inpa participants...
[x] .nil? .empty? .set? for "${x}.nil?"
[o] BlockParticipant : proc.to_source thanks to sourcify
[o] register :overwrite { ... } ? (wipes all the participants)
[o] pause engine
[o] pause process instance
[o] filter : blank? equivalent (maybe it already exists)
[o] eft_18 weak with jruby-1.5.1 and 1.5.6
[o] participant : consume/cancel/accept?/on_reply without params
[o] participant : consume -> on_workitem
[o] remove abort_on_exception=true
[o] concurrence / concurrent_iterator : merge_type => 'discard' / 'ignore'
keep track of the first "process sub id" ?
[o] register :toto, :accept? => lambda { |workitem| ... }
[o] register :toto, :do_not_thread => lambda { |workitem| ... }
[o] :on_timeout => :rewind (break, jump to x)...
[o] :on_error => :rewind (break, jump to x)...
[o] worker identification/registration
http://groups.google.com/group/openwferu-users/browse_thread/thread/c51b94fb8bb685da
[o] worker shutdown initiated by engine (same thread)
[o] set :var => 'y' { '2342342' }
[o] wfid generator UTC?
[o] iterator: drop the need for the sequence --> implicit sequence
[o] citerator: drop the need for the sequence --> implicit sequence
[o] move test/unit/storage[s].rb to test/functional/

[x] exp : filter
[x] exp : filter-definition
[x] exp : parameter
[ ] exp : log : or could it be a participant ?
[x] wait_for(:participant) what about 'dispatched' instead of 'dispatch' ?
[ ] define without name (__result__)
[ ] participant dispatch thread throttling ?
[ ] tailcall
- is it really necessary? The storage is the limit.
[ ] subprocesses participants (alias ?)

[ ] verify get_last/get_raw logic, no + 0.0001...
[x] spare 1 get_msg by caching msg (but keep 'deleting')
[ ] [un]set_var : via message ? should be ok like that... Not much traffic there
[ ] empty iterator or concurrent-iterator, log ? crash ? empty while...
[ ] shell ? irb ? Shell.new(storage)
[ ] focus on fulldup or json.dup (via fulldup ?)
[ ] should __error__ contain the tree ?
[ ] engine.on_cancel = 'participant_name' // 'subprocess_name'
bof
[ ] participant :ref => '${f:nada}', :or => 'xyz'
(look at OpenWFE manual, this feature already existed in there)
http://www.openwfe.org/manual/ch06s02.html#expression_participant
else-ref... list of participants...
ref="alpha && bravo", ref="alpha||bravo" (|| parallel :( )
[ ] LocalParticipant def consume; handle; reply; end
[ ] find better solution than "get all schedules"
... or discard get_schedules completely
[ ] worker : minuteman, make it cron triggerable
trap SIGUSR1 or USR2
maybe it's expensive to fire a [worker] process each minute
have to write the $$ (pid) somewhere for cron to pick it up
[ ] toto :task => 'maw the lawn', :within => '3d'
alias to timeout
[ ] "business days" plugin

[ ] engine.register_from_dir() have a way to re-evaluate the dir
[o] OR remove engine.register_from_dir()
[o] AND provide a better register &block
[o] provide a mean for a participant to reject a workitem (intra plist)
on_reply and now filter ?
[ ] StorageParticipant#by_store[_name]
maybe : reform the store_name system !
[ ] a run of ruby -w
[x] cursor : previous_command field ? not really necessary with :break_if => x
[ ] storage_participant.by_participant([ a, b, c, d ], opts)
storage_participant.by_participant(a, b, c, d, opts) too
leverage things like
http://wiki.apache.org/couchdb/HTTP_view_API#Querying_Options
2.1.12
[ ] receiver/base.rb : fexp.lookup_variable --> lookup_variable ?
[ ] engine/receiver #reply(workitem or fexp or fei) ?

but, this is a cancel_expression(fei)
[ ] concurrence : add_child ?
How would that impact concurrent_iterator's add_branches ?
[ ] detach / attach segments of processes
[x] clone process ? (could be used by {de|at}tach)
what about participants ?
[ ] console for InformatiQ / console or dashboard or tool ?
[ ] pooltool.ru : there are already storage copy methods
[o] doc : enhance doc on conditional (and, empty, null, ...)
[o] doc : document engine.on_{error|terminate}
[o] doc : document on_error = retry and on_error = pass
[ ] doc : add piece of doc about running workers on their own

well... there is already on_error...
but on_error is for nested stuff...
[o] listen to tags {entering|leaving}
[x] listen to launch/terminate, listen :process => :x, :upon => 'launching'
you can now set :tag on a subprocess' define
[ ] listen to [un]set variable (the events are already in there)
not really necessary... there is already 'once' (when)
[o] listen condition ? :when => '${x} == y', :constraint, :only, ...
it's :where and it's not documented :-( but it's tested :-)
[o] engine#on_terminate, similar to on_error
[o] let engine#on_error use svc/tracker.rb instead of 'notifications'
[ ] process supervise other process, listen...
launch a process with a designed 'supervisor' ?
listen to termination, listen to error, for a given process ?
