cmake - How to use different tool chains -


in project targets build , run on build platform , other targets build cross platform; options have, when using cmake?

currently use cmake_build_type define tool chain, build type , platform (for example -d cmake_build_type=arm_debug). in 1 place in build, switch tools (compilers, linke etc.), command line flags, libraries etc. according value of cmake_build_type. every build type, create build directory.

this approach has it's drawbacks: multiple build directories , no easy way depend 1 target 1 build type on target in other build type (some kind of precompiler needed on build platform build cross platform example).

as every build targets has single tool chain used love associate target target platform / tools set. implies libraries have build more 1 target platform different tool sets.

the 'one build type , platform per cmake run' limitation fundamental , advise against trying work around it.

the proper solution here seems me split build several stages. in particular, scenario target 1 build type depends on target build type, should not try have 2 targets in same cmake project. proper modularization key here. effective use of cmake's include command can avoid code duplication in build scripts.

the big drawback of approach build process becomes more complex, have several interdependent cmake projects need built in order specific configurations. although seem way beyond point can build whole system single command anyway. cmake can manage complexity tools externalproject, allows build cmake project within another. depending on particular setup, non-cmake layer written in favorite scripting language might viable alternative ensuring different subprojects built in correct order.

the sad truth though complex build setups hard manage. cmake great job @ providing number of tools tackling complexity cannot magically make problem easier. of limitations cmake imposes on user there reason, namely things even harder if tried work without them.

apache - PHP Soap issue while content length is larger -

we have developed soap based webservice post data third party webservice. accepts 4 params. in 1 of parameters accepts xml string no size limit restriction put in place. the webservice works fine in local environment running on php 5.2 , apache2. works content length long 10 mb. in staging server running nginx , php fpm.we have updated max post size , max upload filesize in php.ini , client_max_body param in nginx.conf allow upto 50 mb. but webservice client keeps on loading in staging environment. gives 502 timeout , gives soap error. can me understand issue here?

asynchronous - Python asyncio task got bad yield -

i confused how play around asyncio module in python 3.4. have searching api search engine, , want each search request run either parallel, or asynchronously, don't have wait 1 search finish start another. here high-level searching api build objects raw search results. search engine using kind of asyncio mechanism, won't bother that. # no asyncio module used here class search(object): ... self.s = some_search_engine() ... def searching(self, *args, **kwargs): ret = {} # raw searching according args , kwargs , build wrapped results ... return ret to try async requests, wrote following test case test how can interact stuff asyncio module. # here testing script @asyncio.coroutine def handle(f, *args, **kwargs): r = yield f(*args, **kwargs) return r s = search() loop = asyncio.get_event_loop() loop.run_until_complete(handle(s.searching, arg1, arg2, ...)) loop.close() by running pytest, return runtimeerror: task got bad yield : {results s...

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
