Extend trepctl to include simple_services and super_trepctl features #516

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
1. To which tool/application/daemon will this feature apply?

Replicator management.

2. Describe the feature in general

The output of trepctl is developer oriented, not user oriented. The information 
is given in a way that is hard to use for beginners. (Include simple_services 
and super_trepctl in regular distro).

6. Notes

Reported by Giuseppe.

Rather than including new tools, it would be better if trepctl could provide 
the same functionality. Probably fixed when Issue#499 is completed

We'll use 2.1.0 instead of 2.0.8, hence moving the issues.

Moving out to 2.1.1.

Moving to 2.1.2, but increasing priority.

simple_services is a filter that displays services in a condensed way.
trepctl services | simple_services
alpha  [slave]  seqno:         10  - latency:   0.742 - ONLINE

bravo  [slave]  seqno:          5  - latency:   0.390 - ONLINE

delta  [master] seqno:          0  - latency:   1.059 - ONLINE

trepctl services | simple_services --action=list
alpha,bravo,delta

trepctl services | simple_services --action=list --role=slave
alpha,bravo

trepctl services | simple_services --action=name --role=slave
alpha
bravo

super-trepctl is a wrapper to trepctl that offers additional features.

Its default output is like simple_services
super-trepctl
alpha  [slave]  seqno:         10  - latency:   0.742 - ONLINE

bravo  [slave]  seqno:          5  - latency:   0.390 - ONLINE

delta  [master] seqno:          0  - latency:   1.059 - ONLINE

it supports several actions: 

super-trepctl --action masterof
master of alpha: host1
master of bravo: host2
master of delta: localhost

super-trepctl --action offline --role=slave

super-trepctl
alpha  [slave]  seqno:         -1  - latency:  -1.000 - OFFLINE:NORMAL

bravo  [slave]  seqno:         -1  - latency:  -1.000 - OFFLINE:NORMAL

delta  [master] seqno:          2  - latency:   0.724 - ONLINE

super-trepctl --host=host1 --action=heartbeat 
(finds the master service in host1 and issues a heartbeat)

How does super-trepctl "masterof" work? Does it do calls across different hosts?

masterof (which was written more than one year ago) uses two calls to trepctl. 
The first call goes to 'services' and gets the name and role. The for each 
service it calls 'trepctl status' and gets the master from masterConnectUri.

With the recent feature 'services --full --json', the same result can be 
achieved with a single call.

Will not use third version digit for normal releases anymore. It will only be 
increment for maintenance ones.
