okhttp - Instrumenting OkHttpClient -

-

i'm writing small wrapper library that'll allow me monitor internals of okhttpclient using dropwizard metrics: https://github.com/raskasa/metrics-okhttp.

i'm having trouble instrumenting connectionpool - specifically, periodically calling getconnectioncount() monitor number of open tcp connections.

when instance of okhttpclient created, getconnectionpool() null - i'm expecting. also, subsequent attempts access pool still return null during/after executing network requests.

i'm assuming there proper way monitor connectionpool because part of public api, i'm not seeing @ moment.

so:

  • is there way access connectionpool @ point okhttpclient.getconnectionpool() not null?
  • if isn't best approach, advice going better way?

try this:

okhttpclient client = ... client.setconnectionpool(connectionpool.getdefault());

that'll give same connection pool you'll anyway, it'll give sooner.

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

-
i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .

Qt4: how to send QString inside a struct via QSharedMemory -

-
i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
