#2159 closed Enhancement (worksforme)

Write a summary of variables alt-speed-... on the Wiki

Reported by: blackjancsi Owned by: Waldorf
Priority: Normal Milestone: None Set
Component: Wiki Version: 1.61
Severity: Normal Keywords:


Even after a lot ot time spent, I could not localise solid info on how exactly the scheduler and its assigned variables work. Bundled with a lack of alt-speed- commanding capability for either the web client or transmission-remote, this is quite a showstopper for headless systems (which are mainly commanded through the above interfaces). This is a pity, considering that transmission is by far the best p2p-app. for them because of its small memory footprint.

Severity is difficult to judge, for headless systems, this is Major/Critical?, for anything else probably Minor (as those are commanded by the more advanced interfaces).

See ticket:2148 if you want to see various stages of the search... :-)

Fixed: Scheduling. Thanks for reporting this!

My pleasure, and great job, especially with the alt-speed-time-day, with no info on it, that was a little hard to figure out before... ;-) A small modif request for the linuxually challenged, though: "Note: When enabled, this will toggle the alt-speed-enabled setting." As someone who did not go through the source code (I know, what a noob...), and who only does some Matlab coding for his PhD in Plasma Physics, i.e. fusion reactor research (no kidding), I found it a little challenging to understand how the whole turtle scheme works (based on the params). And for anyone who messes around with headless systems (like I do, as I prefer burning 20 W instead of 250 W continously), parametrising the daemon like this is necessary.

The main "difficulty" here (conceptually) was that some params are switches (i.e. one-off parameters that stay as they are, e.g. the alt-speed-...-settings, the alt-speed-time-enabled, etc) and then there is one which is a status indicator (alt-speed-enabled), which toggles automatically based on the other scheduling params.

So, in short, I suggest this:

Note: If this is enabled, the alt-speed-enabled parameter will automatically change between false and true as time passes between different scheduling periods, and along with it, the speed settings will toggle between speed-limit-... and alt-speed-... params.

instead of

Note: When enabled, this will toggle the alt-speed-enabled setting.

Also, on another note (this should be a quick change), in the wiki, the other speed-related params are also not up to date, there is

# download-limit: Number (KB/s, default = 100)

# download-limit-enabled: Boolean (default = false)

# upload-limit: Number (KB/s, default = 100)

# upload-limit-enabled: Boolean (default = false)

but in 1.61 those have been replaced by

"speed-limit-down": 150,

"speed-limit-down-enabled": true,

"speed-limit-up": 10,

"speed-limit-up-enabled": true,

Btw, what is the rationale for having the params "speed-limit-down-enabled" and "speed-limit-up-enabled"? I find their existence quite confusing once contrasted with the parameter alt-speed-enabled, which is a toggle parameter that chooses between the two sets of speed settings, whereas the other ones simply mean whether your p2p has unlimited speeds or not. My suggestion for this:

  • Rename "alt-speed-time-enabled" to "scheduling-active"
  • Rename "alt-speed-enabled" to "scheduling-state-slow"
  • eliminate both "speed-limit-down/up-enabled" and just set the speed-limit-up/down defaults on unlimited (or a HUGE number like maxint or something, as I guess it has to be a number) - which would boil down to the same thing as having those two on "false" - and after all, having 2 less parameters is probably a pretty good thing...

thx. didn't notice that. however, the values have not changed.

Your sugestions are more confusing (to me and charles, at least). If you want an easy settings with more description and other bells and whistles, then use a GUI. eg. the new QT-based interface will allow you to connect to a (remote) daemon.

The main "difficulty" here (conceptually) was that some params are switches [...]

Personally, I don't think it needs more words. I did update the other note, however.
