Update duration is more than 24h?

[zyuyou]

func (u *Updater) wantUpdate() bool {
    path := u.getExecRelativeDir(u.Dir + upcktimePath)
    if u.CurrentVersion == "dev" || readTime(path).After(time.Now()) {
        return false
    }
    wait := 24*time.Hour + randDuration(24*time.Hour)
    return writeTime(path, time.Now().Add(wait))
}

Why can I update just once in 24 hours and more?

There isn't a reason, just a sane default. Maybe this should be a field on the Updater struct?

[zyuyou]

I wanted it to be updated when I restarted the app, why should I set an duration to stop my way? So I think that it should always checking for updates when the app restarting.

[sanbornm]

That check is to limit how many times it looks for an update regardless of when an app is restarted. If your app was running for 4 days it would check 4 times by default. Even if you never restart your app.

[zyuyou]

Yes, I see. But I mean, it should check for updates at that moment when the app is starting. For now，the update duration may make it stop.

Some steps:

1. version-1 would write next wanted check for update time to cktime file.
2. version-2 is out, I would like to restart app to update version-1 to version-2.

But it won't work, because readTime(path).After(time.Now() is true. Unless I move cktime file away.

I agree you should be able to set a periodic check time as well as check on app start. I am open to pull requests if you want to make the change.

[zyuyou]

Yes, I want this feature. Thank you.

do you have any idea if people actually use this repo in 2020? ForceCheck doesn't appear to actually force checks and I ran into the same thing zyuyou did. I'd be willing to open a PR but can't get this to work in general so trying to decide if the community could use the PRs/effort or if I should just write something myself for my specific purpose

[sanbornm]

@stevenaldinger I still use it. I don't use ForceCheck or have a need to check on every app startup. I don't think a PR was ever submitted for either of these issues.

Also, I need to use this again for another project very soon. I'll review, test, and approve any PRs/efforts if you want to contribute. It looks like I also need to update this project to use Go modules and do some general cleanup.
