Tested 9bb48bf on Linux Mint 20.3 (Qt 5.12.8) -- the "Network Traffic" tab shows a black window.

shaavan · 2022-01-16T07:08:39Z

Updated from 9bb48bf to 5e6ad43 (pr524.02 -> pr524.03)
Addressed @jonatack and @hebasto’s suggestions.

Done proper casting of m_range variable from mins to milliseconds.
Used duration_casting instead of static_casting, as suggested by @hebasto. The reason for doing so is explained in this article.
Incorporated other nit suggestions.

Tested that the network traffic graph is working correctly now.

Approach ACK 5e6ad43, tested on Linux Mint 20.3 (Qt 5.12.8).

About commit message:

please use "qt: " prefix (see https://github.com/bitcoin-core/gui/blob/master/CONTRIBUTING.md#creating-the-pull-request)
what about "qt, refactor: Use std::chrono in TrafficGraphWidget class"?
references like PR#517 do not work well with separated repositories that use the monotree; you could use bitcoin-core/gui#517, or just drop it

Just remove? It's not used.

@promag @shaavan

I concur - It appears to be part of the original implementation but never used for anything...

it can and should be removed...

shaavan · 2022-01-31T10:49:54Z

I use int TrafficGraphWidget::getGraphRangeMins() const in PR #539 (which fixes issue #532)

I looked through #532, but I couldn't find any use case of getGraphRangeMins() there. So I don't think there should be an issue removing this function in this PR.

I have added a variation of this PR to #539 c25d3f4 to ensure compatibility with the chrono lib.

I looked through it, and it looked good. However, I reckon the primary purpose of #539 is to fix an issue by adding a scaling feature. And the purpose of this PR is refactoring. So I think it would be best to keep these PRs separate.

RandyMcMillan · 2022-02-01T00:02:58Z

If you insist - but to scale the graph - we will have to know the current value of the slider - otherwise the graph can't calculate how many samples to display. It will have to be re-added - it is easier to leave it in.

#539

shaavan · 2022-02-01T07:30:59Z

It will have to be re-added - it is easier to leave it in.

I think you are right. Let me keep the GetGraphRange() function and make it consistent with the previous changes.

shaavan · 2022-02-03T10:11:35Z

Updated from bdf7cb9 to cad0e0a (pr524.06 -> pr524.07, diff)
Addressed @RandyMcMillan comment

Changes:

Restored the getGraphRange() function, as it is used in Scale network graph based on time interval #539. So removing and re-adding the function doesn’t seem optimal.

The updated PR correctly compiles on Ubuntu 20.04, with the Network Traffic widget showing the correct graph.

shaavan · 2022-02-03T11:41:20Z

Reverted back to f7a19ef (pr524.07 -> pr524.04, diff)

Reason:

The is almost no difference between pr524.07 and pr524.04 (see the diff).
f7a19ef had quite a few ACKs behind it, by:

P.S.: To avoid any unintended changes between the PR and f7a19ef, I used the following command to update the PR:

git reset --hard HEAD^
git cherry-pick f7a19ef774ef92ce348215593e3590a750c345e1

The commit id has changed (which I was not able to restore) but the changes are identical f7a19ef

shaavan · 2022-02-04T10:11:27Z

Restored PR to previous commit f7a19ef. The reason for doing so is explained here: #524 (comment)

P.s.: Thanks, @hebasto, for your help in restoring this commit.

RandyMcMillan · 2022-02-08T18:33:50Z

@shaavan - thanks for leaving that function in - @rebroad and I have work that utilizes this.
