performance - Possible with lua in redis to return all key stored in a set as a list of hashes? -


i have structure

data_type:key1 - hash data_type:key2 - hash data_type:key3 - hash data_type:key4 - hash data_type:key5 - hash data_type:index - set(key1, key2, key3, key4, key5)

is possible lua in redis build script iterate on set data_type:index , return data_type:key*'s list of hashes? still learning lua go in head think work like

collect = [] key_name in redis.call.smemembers('data_type:index'):     collect.append( redis.call.smembers('data_type:' + key_name) return collect

generally of index's have 100 keys, each key 1kb, script have 100-120kb response size under ideal circumstances.

and before asks, real keys 'some_data:status:{64 bit hex string}' , 'some_data:index:2013:05:09' {64 bit hex string} being member of :index set.

check sscan command.

something following should work in case: 

local collect = {} local match_pattern = "*" local results = redis.call("sscan", "data_type:index", 0, "match", match_pattern) i, key_name in ipairs(results[2])    -- code here (could different depending on needs)   local key_value = redis.call("get", "data_type:" .. key_name)   if key_value     table.insert(collect, key_value)   end  end  return collect

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
