Vimperator: 3.15.0 (created: 2016/10/08 06:55:36)

Description:

When i updgraded vimperator to version 3.15 i discovered constant lagging when i tried work with commandline. For example, when i type ab and try to autocomplete that to about:support, with pressing Up only once, it's autocompletes with delay.

I found commit that was cause of it and compile without it, and it's gone: https://github.com/vimperator/vimperator-labs/pull/587

~~With a fast machine this is only slightly noticeable, but you are able to notice it. On a slower machine I observed a rather long lag.~~

~~Maybe it's the regular expression matching that slows it down.~~

~~Until a solution is found I suggest to revert 52b7f94e46dd09057e30c9c62e2f3233d68c5eb2.~~

Now I cannot reproduce it anymore. Maybe something else. :/

But it still seems to be here for @stepshal and probably others? If this commit is really the cause, I am for reverting it. Working on the commandline should always be fast.

@maxauthority Yes, i am for reverting it. For some reason with current build first entry is autocompletes without lag, but if you try to autocomplete to the next, lag is still here.

@stepshal That is interesting. Can you please describe exactly what you do to reproduce this?

I think it's not the completion but the history that became slower. And I tried it on an old (=slow) computer and can reproduce it with this sequence:

1. Press :set
2. Press ↑ multiple times, each results in a slight delay

After reverting 52b7f94e46dd09057e30c9c62e2f3233d68c5eb2 it is fast again.

Maybe it is history. For me:

1. Press :tabopen
2. Type ab
3. Press ↑ to autocomplete to about:pages, each result in a 1 second delay (3.15 version), and only after first entry delay appears (master). And youtube.com was freezing each time i open it for a long time for some reason with it.

@timss maybe just revert this commit?
