GeoServer times out (504 Gateway Time-Out) when accessed from OpenLayers via nginx webserver -


i have developed openlayers web app uses geoserver. using nginx webserver proxy_pass setup geoserver. works expected when use "localhost" when switch ip address 504 gateway time-out error for

http://98.153.141.207/geoserver/cite/wfs.

i can access geoserver at

http://98.153.141.207/geoserver/web

via browser without problem appear proxy continues work expected.

the geoserver log shows when problem occurs:

request: describefeaturetype     service = wfs     version = 1.1.0     baseurl = http://98.153.141.207:80/geoserver/     typename[0] = {http://www.opengeospatial.net/cite}mylayer     outputformat = text/xml; subtype=gml/3.1.1

then after minute, 504 gateway time-out in javascript console , shows in geoserver log:

09 may 06:02:15 warn [geotools.xml] - error parsing: http://98.153.141.207/geoserver/wfs/describefeaturetype?version=1.1.0&typename=cite:mylayer

i have tried supposed problem url in browser , works fine.

the nginx erorr log contains this:

2013/05/09 06:02:15 [error] 420#3844: *54 upstream timed out (10060: connection attempt failed because connected party did not respond after period of time, or established connection failed because connected host has failed respond) while reading response header upstream, client: 98.153.141.207, server: localhost, request: "get /geoserver/wfs/describefeaturetype?version=1.1.0&typename=cite:mylayer http/1.1", upstream: "http://127.0.0.1:8080/geoserver/wfs/describefeaturetype?version=1.1.0&typename=cite:mylayer", host: "98.153.141.207"

further investigation reveals problem seems restrict wfs layers only. wms layers work fine. here declaration of wfs layer fails:

mylayer = new openlayers.layer.vector("mylayer",                                     {                                       strategies: [new openlayers.strategy.bbox(),savestrategy],                                       projection: "epsg:2276",                                       protocol: new openlayers.protocol.wfs(                                       {                                         version: "1.1.0",                                         url: "http://" + hostip + "/geoserver/cite/wfs",                                         featurens: "http://www.opengeospatial.net/cite",                                         srsname: "epsg:2276",                                         featuretype: "mylayer",                                         geometryname: "poly",                                         schema: "http://" + hostip + "/geoserver/wfs/describefeaturetype?version=1.1.0&typename=cite:mylayer"                                       })                                     });

any appreciated. thanks

i managed working remove "schema" property openlayer.protocol.wfs of layer. can explain why problem?

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...

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...
