regex - Apache mod_rewrite rule for complex sitemap + index xml files -


we manage sitemap (sitemap.org) files have in range of 500k links, changing enough want dynamically generate them, don't worry, we'll cache results period it's mod_rewrite rules i'm having problem with.

being have more 50k links need using sitemap index files. both sitemaps , index files redirected sitemap.php file use filename pattern ($_server['request_uri']) figure out list present.

the filename patterns follows:

www.domain.com/sitemap.index.xml www.domain.com/sitemap.some_theme.xml www.domain.com/sitemap.different_theme.xml

the mod_rewrite covers off our web application i'll include of in case else may overriding or conflicting i'm trying accomplish:

rewriteengine on rewritecond %{request_filename} -s [or] rewritecond %{request_filename} -l [or] rewritecond %{request_filename} -d rewriterule ^sitemap\.(.*)\.xml$ sitemap.php/ [nc,l] rewriterule ^.*$ - [nc,l] rewriterule ^.*$ index.php/ [nc,l] errordocument 404 /

the line i've inserted sitemaps is:

rewriterule ^sitemap\.(.*)\.xml$ sitemap.php/ [nc,l]

otherwise else standard web application stuff.

--- edit ---

ok, after head scratching, found problem. first, simplified rule since didn't need capture pattern match, positive response, new rule is:

rewriterule ^sitemap.*\.xml$ sitemap.php [nc,l]

so kicker swapping order of , 1 below:

rewriterule ^.*$ - [nc,l] rewriterule ^sitemap.*\.xml$ sitemap.php [nc,l]

i'm going leave question open now, because i'd know why made difference. thanks.

this rule redundant , should removed:

rewriterule ^.*$ - [nc,l]

modify code this:

options +followsymlinks -multiviews # turn mod_rewrite on rewriteengine on rewritebase /  errordocument 404 /  rewritecond %{request_filename} -s [or] rewritecond %{request_filename} -l rewriterule ^/?sitemap\. /sitemap.php [nc,l] rewriterule ^ /index.php [l]

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...
