i have complex recursive function in node.js, sake of question simplified following: function sum(tree) { if (!tree) return 0; var sumleft = sum(tree.left); var sumright = sum(tree.right); return sumleft + tree.val + sumright; } var exampletree = { val: 3, right: { val: 4 }, left: { val: 5, right: {val: 6}, left: {val: 7} } } console.log(sum(exampletree)); // returns 25 = 3+4+5+6+7 now want convert function "sum" asynchronous function: function sumasync(tree, callback) { // ??? } but, since function doesn't return value, don't know how values sumright , sumleft , combine them. one possible option totally rewrite algorithm such iterative , not recursive (as suggested in question: how make synchronous recursive function asynchronous ). but, in many cases might complicated , make entire program unreadable. there solution keeps simple structure of recursive function, while making asynchronous? note: pr...

i using django rest server. suppose post contains json should parse. client salesforce server gzipping request. to request inflated, use in vhost: setinputfilter deflate almost looks fine, when read request.body or request.read(16000) - input pretty small - see chopped response (5 characters missing). any suggestions start debugging? technically wsgi specification doesn't support concept of mutating input filters middleware, or within underlying web server. the specific issue mutating input filters change amount of request content, not change content_length value in wsgi environ dictionary. the wsgi specification says valid wsgi application allowed read content_length bytes request content. consequence, in case of compressed request content, final request size end being greater content_length specifies, web framework truncate request input before data read. you can find details issue in: http://blog.dscpl.com.au/2009/10/details-on-wsgi-...

i have following problem i have 2 table on database respectivelly named vulnerabilityalertdocument , vulnerabilityreference bind togheter table named vulnerabilityalertdocument_vulnerabilityreference contains 2 fields: id of first table ( vulnerabilityalertdocument ) , id of second table ( vulnerabilityreference ) now if try delete record vulnerabilityalertdocument sql server me can't because exist referential integrity constraint. so if want delete record vulnerabilityalertdocument have following operations: i have select rows in vulnerabilityalertdocument_vulnerabilityreference first field id of record want delete vulnerabilityreference i have delete corresponding record vulnerabilityreference finaly have delete these row vulnerabilityalertdocument_vulnerabilityreference i think correct solution have problem understand how can store result of selection in vulnerabilityalertdocument_vulnerabilityreference can me? i think got order of operations w...

i draw triangle, 1 of sides needs circle segment. example not working: blue outside circle needs removed. can done directly, without calculating entire contour myself? thank you! import matplotlib.pyplot plt fig = plt.figure() ax = fig.add_subplot(1, 1, 1) polygon = plt.polygon([(0,0.6),(1,2),(2,0.4)], true) circle=plt.circle((0,0),1.0,facecolor='none', edgecolor='black') ax.add_patch(polygon) ax.add_patch(circle) plt.show() you can use set_clip_path property if capture added patch of polygon. given example: fig = plt.figure() ax = fig.add_subplot(1, 1, 1) polygon = plt.polygon([(0,0.6),(1,2),(2,0.4)], true) circle = plt.circle((0,0),1.0,facecolor='none', edgecolor='black') patch_poly = ax.add_patch(polygon) ax.add_patch(circle) patch_poly.set_clip_path(circle)

i have update panel timer. panel contains repeater has records. use pageddatasource paginate repeater's data. added server method onchange event reloads repeater's page size. event fired when needed data reloads when timer tick executes. therefore, when change page size, need wait entire timer interval see page size changed. explain why happens? appreciated here's of code <form id="linksform" runat="server"> <div> <div style="float: left; background-color: white"> <asp:scriptmanager id="scriptmanager1" runat="server"></asp:scriptmanager> <asp:button id="displayalllinksbt" onclick="displayalllinks" runat="server" text="visi"/> <asp:button id="displaynewlinksbt" onclick="displaynewlinks" runat="server" text="nauji" /> <asp:timer id="timerlinks...
