Can you add a template for the content of a device.json file, when using the -f argument?

In the new flogoapp build process there are a few small issues:

• flogo.json is not in the bin directory
• flogo.json does not have type id for root task
• flogoapp build adds flows.go to it even though it is not needed

Flogo application is crashing when 2 concurrent client hitting PUT & GET requests.

Environment: MAC
Attached zip contains necessary files: flowapp-crash-flogo.json & crash.sh
flowapp-crash.zip

Steps to reproduce the issue:

Step-1:
flogo create -f flowapp-crash-flogo.json flowAppCrash
cd flowAppCrash
flogo build
cd bin
export FLOGO_LOG_LEVEL=ERROR
./flowappcrash

Step-2:

Start new terminal & run ./crash.sh
Start 2nd terminal & run ./crash.sh

You should able see flow app is crashing in 1-2 mins.

Current behavior (how does the issue manifest):
When building an app using a new activity that depends on a Go package "github.com/hyperledger/fabric/core/chaincode/shim", I got the following error:

2019-02-18T22:02:17.517Z - error: # flogo-web/vendor/github.com/docker/docker/opts
vendor/github.com/docker/docker/opts/address_pools.go:15:12: undefined: ipamutils.NetworkToSplit

See the same error in flogo-web when adding the same activity from Flogo UI. We cannot add this activity because "flogo build" failed to build flogo-web.

Expected behavior:
"flogo build" may need a better way to reset dependencies, and so build will succeed. My steps to work around the issue is documented below.

Minimal steps to reproduce the problem (not required if feature enhancement):
add dependency by importing the following in an app or a trigger/activity, then try to build it.

    _ "github.com/hyperledger/fabric/core/chaincode/shim"

What is the motivation / use case for changing the behavior?

Please tell us about your environment (Operating system, docker version, browser & verison if webui, etc):
OSX, Docker desktop, Chrome

Flogo version (CLI & contrib/lib. If unknown, leave empty or state unknown): 0.X.X

Additional information you deem important (e.g. issue happens only occasionally):
To work-around the issue, I had to reset the Go dep by the following steps:

cd myapp/src/myapp
rm -Rf Gopkg.* vendor
dep init

To fix the same build issue in flogo-web, I had to do the same in the flogo-docker container. In addition, I had to add an extra lib to the docker container for UI:

apk add --no-cache musl-dev

This will include the flogo_old executable, and other things.

Separate flogo cli into two executables. One that for a high-level flogo user that only addresses app creation. And another that is for a contribution developer that used to create scaffolding to assist in the development of flogo contributions (triggers, actions, activities, etc..).

Following the readme:

Installed Go latest
Set Go Path - export PATH=$PATH:/usr/local/go/bin
Installed gb - go get github.com/constabulary/gb/...
Installed Flogo - go get github.com/TIBCOSoftware/flogo-cli/...
Download myflow.json to work folder
run - ./flogo create myApp

Error: Cannot create flogo project [myApp], gb is not installed

Am I missing something here? Thanks!

Hi,
I am trying to install activities through cli but getting below errors.
Any suggestions?

flogo install github.com/TIBCOSoftware/flogo-contrib/activity/log

I try to do the getting started step-by-step. I installed everything successfully. However, the command "flogo add flow myflow.json" fails.
I assume the reason is that there is no file "myflow.json". Do I have to create this file first? The readme does not give any additional hints.

In addition, it would be great if the readme explains how flogo-cli and flogo-web are related. Or can you use either one to build the same flows ?!

Hi,

importing the following app:
https://github.com/TIBCOSoftware/flogo-cli/blob/master/docs/samples/devices/device-l0x.json

gives me an error because the trigger "has not been installed"

Actually, it seems that it is just because the path to the trigger is not correct.

Instead of:
{ "id": "l0x_trigger", "name": "Read From VL53L0X", "ref": "github.com/TIBCOSoftware/flogo-contrib/device/trigger/vl53l0x_stream", "actionId": "monitor_dist", "settings": { "interval": "500" } }

it should be:
{ "id": "l0x_trigger", "name": "Read From VL53L0X", "ref": "github.com/TIBCOSoftware/flogo-contrib/device/trigger/vl53l0xstream", "actionId": "monitor_dist", "settings": { "interval": "500" } }

Philippe

Right now only version 1.7 will compile our code, so we should mention the minimum version in docs.

I have a problem when I was trying to get the Flogo cli on my Mac OS:

When flogo create or add issued , the cli does go get from github and it will pick the latest code which is uncontrolled from a build perspective.

On the "add" it can partially address it by supporting "@Version" for example flogo add activity github.com/.../[email protected], but it is not possible control the versions of that activity's dependencies at the moment.
Dave Cheney(creator of gb) have been contacted concerning this, and gb is working on adding support for this. Hopefully Go can figure out some basic dependency management in the near future.

We should prevent 2 activities with the same name to be added to the engine using the command:

flogo add activity myActivity

If you call this command twice, two activities with the same name will be added to engine configuration 'flogo.json' file.

Change log from github.com/op/go-logging to flogo-lib logger wrapper

When entering a cmd with an incorrect syntax we should display the correct syntax again. For example the following cmd:

flogo create -f SampleApp2 ~/Downloads/SampleApp.json

Simply yields the following error. The correct syntax should be displayed again after the error.

Error: Error loading app file 'SampleApp2' - open SampleApp2: no such file or directory

We need a way to choose what version of libraries will be used in a flogo project.

When the app name specified in flogo json does not match the dir name, the app fails to execute after being built.

If you develop locally a trigger or activity, and if you use a third party go package, then you have to manage manually the copy of the 3rd party package under [flogo_app_dir]/vendor/src directory (this is done automatically when using 'flogo add activity' using an activity fetched from github.com

I have created flogo app using flogo web. It contains simple Rest trigger with Rest invoker and Reply to trigger legacy one. I am not getting output in browser. Attached flogo.json for reference.

Steps to reproduce:

1. Create flogo app with attached json and start the binary.
2. Open browser hit the "url http://localhost:9096/pet/1"
3. I am getting empty page check the attached error.jpg

Observation:
I have changed output params value to null instead of empty array in metadata section. I can see the response in browser.

FATAL: command "build" failed: exit status 1

I followed the README.md steps and did not manage to install flogo on Windows:

1. I installed a clean Go instance and set PATH env variable (go version yields go version go1.8.3 windows/amd64)
2. Created a directory called C:\Users\MY_USER\Go\src as suggested by Go
3. Executed go get github.com/constabulary/gb/.... Two directories were created, C:\Users\MY_USER\Go\src\constabulary and C:\Users\MY_USER\Go\src\pkg
4. Executed go get github.com/TIBCOSoftware/flogo-cli/.... Two directories were created, C:\Users\MY_USER\Go\src\TIBCOSoftware and C:\Users\MY_USER\Go\src\xeipuuv

The README.md file starts using flogo commands afterwards but it is not being recognized as a comand. Do I need to build something? Or set some other path to PATH?

I used "flogo create" to create an instance of an app. I then copied over the flogo.json file with a version containing the kafka trigger (rather than hand editing the file) and then attempted the build:

Steps:
Create a flow app
edit flogo.json and add new dependancy (lets say new trigger)
use flogo-cli/app/api.BuildApp() api for building the binary

Issue: newly added dependancies are not getting downloaded.

flogogen trigger test will create template code that has:

trigger.go
// Init implements trigger.Trigger.Init
func (t *udpTrigger) Init(runner action.Runner) {
t.runner = runner
}
rather than Initialize

trigger_test.go

runner := &TestRunner{}
tgr.Init(runner)

is Init correct ?

Create a trigger:
flogogen trigger wcntrigger
Attempt to build the new trigger and you get:
github.com/wnichols/wcntrigger
trigger.go:16: undefined: jsonMetadata

There is no declaration for jsonMetadata. Comment the "init" method out and check the code into github.

make a test flo: flogo create testtrigger
flogo build works and creates a rest service as usual.
Now install the previously created trigger:
flogo install github.com/wnichols/wcntrigger
trigger is installed in the vendor folder.
flogo build now fails with:
trigger_metadata.go:31: undefined: NewFactory

Current behavior (how does the issue manifest):
The flogo build is giving the following issue

[error] Encountered error while installing the 'https://github.com/pradyuz3rocool/flogo-workspace/activity/dhtxx' to the engine:
2018-12-05T10:18:00.268Z - error: # flogo-web/vendor/github.com/pradyuz3rocool/flogo-workspace/activity/dhtxx

FATAL: command "build" failed: exit status 2

Expected behavior:

Minimal steps to reproduce the problem (not required if feature enhancement):

What is the motivation / use case for changing the behavior?

Please tell us about your environment (Operating system, docker version, browser & verison if webui, etc):

OSX Mojave, Docker engine 18.09.0, chrome, logo v0.5.6
Flogo version (CLI & contrib/lib. If unknown, leave empty or state unknown): 0.X.X

Additional information you deem important (e.g. issue happens only occasionally):

After adding trigger, and the activity to app, the "flogo build" step gives following error:

github.com/TIBCOSoftware/flogo-lib/core/data
coercion.go:38: undefined: MAP
github.com/TIBCOSoftware/flogo-lib/util
github.com/julienschmidt/httprouter
github.com/op/go-logging
FATAL: command "build" failed: exit status 2

Looks like, the MAP type needs to be defined in https://github.com/TIBCOSoftware/flogo-lib/blob/master/core/data/types.go

Code synch up done on 04/19/2016, AM.

We need a command that will tell us what version of the cli is currently run.

This will help us with issues and debug problems to make sure people are running the correct version.

In github.com/TIBCOSoftware/flogo-cli/tools/trigger/files.go template the Stop() method is missing error as return value to match the Managed interface in github.com/TIBCOSoftware/flogo-lib/util/managed.go.

This creates an error when building a custom Trigger.

In github.com/TIBCOSoftware/flogo-cli/tools/activity/files.go template the Eval() method has the wrong type of error.

This creates an error when building a custom Activity.

flogo package contains commands code, we need to change this.

Rename the flogoapp cmd to flogo and deprecate the original flogo cmd.

Hi there,
probably more a documentation issue at this point, and a request for guidance to get an first app running.
What i wanted to do is take the weather app example from flogo-web and run it using flogo-cli
I ran the app successfully on flogo-web and exported the flow using "Export for CLI" (generated file : "weather_flow.json")

Here is what I did:

flogo create weather_app
cd weather_app
flogo add activity github.com/TIBCOSoftware/flogo-contrib/activity/log
flogo add activity github.com/TIBCOSoftware/flogo-contrib/activity/rest
flogo add activity github.com/TIBCOSoftware/flogo-contrib/activity/twilio
flogo add trigger github.com/TIBCOSoftware/flogo-contrib/trigger/rest

I updated the bin/triggers.json to configure my rest trigger
so far so good.
then I tried to add my flow using the generated "weather_flow.json"

flogo add flow weather_flow.json 
Error: cannot embed 'weather_flow.json', validation of the flow's json failed:
  - model: model is required
  - type: type is required
  - rootTask: rootTask is required

This creates error as you can see above.
I don't mind updating manually my flow json file, but I cannot find anywhere a document that describes how to write it ? Did I miss it ?

One side remark: the Readme's sometimes mention the possibility to use Slack to ask questions. But this on a Slack team I don't belong to:

1. either there is a process to join the Slack team, and then this should mentioned
2. or this is a restricted Slack team, and then you should remove this from the Readme's

Thanks,
Eric

consider running dep ensure after the shim.go has been moved to main.go, in the event the shim imports packages that are not part of the original import tree

I'm starting with Flogo. I've install Go 1.7.5 on a RaspeberryPi 3B and I can compile a Go app.

I've followed the pre-requisit steps without any error, but I'm getting an error when I try to create the project:
$ go get github.com/constabulary/gb/...
$ go get github.com/TIBCOSoftware/flogo-cli/...
$ ls $GOPATH/pkg/linux_arm/github.com
constabulary pkg TIBCOSoftware xeipuuv
$ pwd
/home/pi/work/src
$ flogo create helloflogo
bash: flogo: command not found

Do I need to manually add flogo bin to the path? If yes, please add this to the get started steps.

When we create a new Trigger or Activity we need to create an initial default ui structure

Current behavior (how does the issue manifest):
flogogen trigger generates an incomplete _test.go Currently it is possible to take the trigger as generated and test it.

Expected behavior:
Similar to activity. Would have expected the generated trigger to 'work'
Minimal steps to reproduce the problem (not required if feature enhancement):
flogogen trigger testTrigger
cd testTrigger
go test
What is the motivation / use case for changing the behavior?

Please tell us about your environment (Operating system, docker version, browser & verison if webui, etc):

Flogo version (CLI & contrib/lib. If unknown, leave empty or state unknown): 0.X.X

Additional information you deem important (e.g. issue happens only occasionally):

System: macOS. go version go1.8.1 darwin/amd64

When running flogo build without -sp the following error occurs. The build succeeds when running with -sp.

Current behavior (how does the issue manifest):
The code adds an additional GOPATH entry to cmd and under certain circumstances it does not work

Expected behavior:
Only one GOPATH entry in the env when running "cmd"

Minimal steps to reproduce the problem (not required if feature enhancement):

What is the motivation / use case for changing the behavior?

Please tell us about your environment (Operating system, docker version, browser & verison if webui, etc):

Flogo version (CLI & contrib/lib. If unknown, leave empty or state unknown): 0.X.X

Additional information you deem important (e.g. issue happens only occasionally):

When flogo create or add issued , the cli does go get from github and it will pick the latest code which is uncontrolled from a build perspective.

On the "add" it is possible to partially address it by supporting "@Version" for example flogo add activity github.com/.../[email protected], but it is not possible to control the versions of that activity's dependencies at the moment. Dave Cheney(creator of gb) has been concerning this, and gb is working on adding support for this. Hopefully Go can figure out some basic dependency management in the near future.

For the create we can also add a "-libVersion" or something to allow you to specify the specific version of flogo-lib

Clean up the shim build code. Specifically the ensure and regeneration of metadata
