Similar to go-sdk, we should avoid using fabric pkg as dependencies

HI sir，

How to Communicate with peer by proxy using your Tape？ thank you！
Like this：

peers:
  peer0.adminorg.544330u:
    url: grpcs://181.71.124.24:30062
    grpcOptions:
      ssl-target-name-override: nginx.bc9seqlghk0u.baas
      grpc.primary_user_agent: /peer0-adminorg.bceqlghk0u
      grpc.keepalive_time_ms: 600000
    tlsCACerts:
      path: networks/cert/nginx.bc9qlghk0u.baas.pem

My config.yaml is written like this

private_key: /home/niqinyin/go/src/github.com/kongyixueyuan.com/education/fixtures/crypto-config/peerOrganizations/org1.kevin.kongyixueyuan.com/users/[email protected]/msp/keystore/c24c159c6de601f2703c4e4273682b08cda54ebdaf4ca1c4aa4b3f80b8a91964_sk

I've tried the user's private key, too.But it always reported such an error

ERRO[0000] error connecting to localhost:7051: failed to load client certificate: tls: private key does not match public key

please help me

Bug:

Hint: Let's decouple Tape bug with general issues as TLS cert config error,general performance testing issue as resource been eat up, or fabric bugs.
Hint: For any platform specific issues, please try to reproduce by Mac/Linux. For ex, it's hard for Tape maintainers to investigating issue on any kind of IOT device as we don't have your device.

i want to test my fabric，and this error showed up，how can i deal with that?

There's zero integration today in this project. User/Dev must manually spin up a fabric network and try it out. We need a proper integration test that spins up real fabric network and run stupid with light traffic against it

When I write config.yaml, I don't know how to write args.
My function name is "addfile",the type of its parameter is []String ,its parameter is [{"FileName":"1.txt","ID":"121","IPAdress":"1.1.1.2","OrgName":"org2","ModifyTime":"8:27 2019/9/12"}，"eventAddFile"], how should I write the args?
By the way, when calling chain code from the Ubuntu command line, the common command is written like this
peer chaincode invoke --tls --cafile $ORDERER_CA -C mychannel -n mycc -c '{"Args":["get","a"]}'
So how do my functions write commands

As hot fix for CI, we switched to 2.3 version.
So ... we need add Fabric 2.2 in CI scope.

Describe the bug
In the scenario of monitoring multiple peers, if the number of threshold peers receive all transactions, txs can be considered as writed successful. However, the current implementation has a bug. As long as a peer receives all transactions, the monitoring process is deemed to be over and the program exits, which is a big deviation from the original design.
In addition, closing channel finishCh(https://github.com/Hyperledger-TWGC/tape/blob/master/pkg/infra/observer.go#L64) may panic, which has been closed in other goroutines.

To Reproduce

Expected behavior
The threshold in BlockCollector takes affect.

Logs
Attach logs from Tape/Peer/Orderer here. And please format them with markdown!

Additional context
Add any other context about the problem here.

we are using fmt.Println all over places, which should be replaced with proper loggers

We have client_per_conn in config.yaml, which is passed as client int in Proposer:
https://github.com/guoger/stupid/blob/6b3b46f98c82c860f4bec8af76606478977b3ed2/infra/proposer.go#L16

However, this is not used. Effectively, we have one client per connection. We should make use of it (or delete it?)

Nodes to interact with

endorsers:

• *peer1
• *peer2

we might support multi-committer in the future for more complex test scenario,

i.e. consider tx committed only if it's done on >50% of nodes. But for now,

it seems sufficient to support single committer.

We should be able to send tx at constant rate in order to test Fabric durability

Often we need to spot network bottleneck by testing 3 phases Endorsement - Order - Commitment separately:

• generate Proposals to peer and observe endorsement ProposalResponse
• generate Envelope to orderers and observe ordered Block
• generate Block to peer and observed committed Block (this is the most tricky one)

This could help us benchmarking fabric components in finer-grained manners.

Is your proposal related to a problem?

After I successfully ran the Tape in my fabric sample, I got results with three columns: time, block, and tnx.

However, I didn't totally understand what these indicators mean as I have not found related documents in https://github.com/Hyperledger-TWGC/tape .

In addition, where/how can I get results such as latency and TPS.

Describe the solution you'd like

Hope the Tape outputs could be more intuitive or more explanations in README. Thanks

the tps pre block may 1000+ in previouse,

in this case the total tps from 1000+ to 500+ ?

1. When I use tape to test my fabric network, the tape sets 10 transactions in each block by default. I just wondering where I can change this setting? It seems I cannot change it in the configure.yaml.

2. After testing, I quired blockchain height, and I found all the transactions that used for the test were really stored in ledger and can not be removed. So does Tape has a "clear" mechanism like caliper? Thanks

Describe the bug
It works when calling a chaincode from the JS script, but fails in tape. The error is ProposalResponsePayloads from Peers do not match.

Part of my config file
It's strange that when I invoke some simple chaincode functions with short parameters, tape works normally. However it fails with follow parameters in complicated functions.

args:
  - base_tx
  - 04379014e00469b50713374741ff06a39e24c869d6e1855a684c159268ce67331a4af3ca09c4e74e7713e50aedc1d0533d1e3cdded042229d4d093b11bdd46b881

Should we need chaincode level performance testing?

国密支持
仅仅考虑msp和支持国密对于背书的签名支持
不考虑tls

I am fine with current context.
I am not sure, if we'd better refactor this part with link to https://prometheus.io/docs/introduction/overview/ (if we suggestion user use prometheus...)

so that tips can be refactor as:
tips:

1. network samples....
2. monitor tool suggestion....

and I suppose later we are able to use some result from probe to replace Increase number of messages per block in your channel configuration may help, as adjust parameter for xxx may help for sample and ...

but I suppose the content update can be in further version/pr.

also, i think we could have a followup PR to add peer.Pause() and peer.Resume(), so we could assert that threshold takes effect when 2/5 peers are paused

Today, stupid does not care if a block contains invalid transactions (in most cases, it doesn't). However, it might be useful to display success rate by inspecting blocks, especially when multiple peers are supported #10

we should be able to observe multiple peers, to support semantics like "block is considered committed if it's done on >50% peers"

following key metrics section in https://www.hyperledger.org/wp-content/uploads/2018/10/HL_Whitepaper_Metrics_PDFVersion.pdf, we would need to be able to report latency with Tape

1. for release ref https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/utility/github-release?view=azure-devops
2. for golint

if not, we should support it

today, tape only support static and fixed arguments upon start. Although this is way too limited. We need to pick and support a templating language. For example: https://ghz.sh/docs/examples#metadata-using-template-variables

ideally this should be 0, so that system randomly picks an available port. And we dynamically render this port into config file. Not necessarily fix in this PR, pls create a new issue
