Facebook PHP Graph SDK performance issue -


i'm using facebook php sdk v5 simple task: converting javascript short-lived user token long lived 1 , returning it.

the issue i'm having requests seem take long time when issued sdk compared postman or graph api explorer.

in order benchmark have used profiling calls, i'm measuring both high level execution times , lowest level possible (wrapping curl call) make sure issue not related additional php overhead.

$fb = new facebook\facebook([   'app_id' => $options['app_id'],   'app_secret' => $options['app_secret'],   'default_graph_version' => 'v2.10',   ]);  $helper = $fb->getjavascripthelper(); $prev = performancelog($prev, 'fbinit'); try {     $accesstoken = $helper->getaccesstoken(); } catch (\facebook\exceptions\facebookresponseexception $e) {     // when graph returns error     die(500);  } catch (\facebook\exceptions\facebooksdkexception $e) {     // when validation fails or other local issues     die(500); } $prev = performancelog($prev, 'gettoken'); if (!isset($accesstoken)) {     if ($helper->geterror())     {         die(var_dump($helper->geterror()));     } else {         die(500);     } } else {     // oauth 2.0 client handler helps manage access tokens     $oauth2client = $fb->getoauth2client();      // access token metadata /debug_token     $tokenmetadata = $oauth2client->debugtoken($accesstoken);      // validation (these throw facebooksdkexception's when fail)     $tokenmetadata->validateappid($options['app_id']);     // if know user id access token belongs to, can validate here     $tokenmetadata->validateexpiration();     $prev = performancelog($prev, 'validation');     if (!$accesstoken->islonglived()) {         // exchanges short-lived access token long-lived 1         try {             $accesstoken = $oauth2client->getlonglivedaccesstoken($accesstoken);         } catch (\facebook\exceptions\facebooksdkexception $e) {             die(var_dump($e));         }     }     $prev = performancelog($prev, 'getlong');     echo $accesstoken->getvalue();     $prev = performancelog($prev, 'echogetvalue'); }

which standard, profiling times are:

init : 0.15900301933289   fbinit : 0.0040819644927979   gettoken : 1.5706379413605 of request : 1.566477060318   validation : 1.5675730705261 of request : 1.5646359920502   getlong : 0.56497001647949 of request : 0.56240797042847  echogetvalue : 4.0531158447266e-6

am doing wrong? there other solution besided caching? keep in mind times variable: go 3 seconds around 12, times out.

thanks

telegram's inline keyboard great feature lots of different use cases. inline buttons added list of items this: inline_keyboard = [[inlinekeyboardbutton(text="button", callback_data="button"), inlinekeyboardbutton(text="reset",callback_data="reset")]] inline_keyboard_markup = inlinekeyboardmarkup(inline_keyboard) update.message.reply_text("hi", reply_markup=inline_keyboard_markup) the above code adds 2 buttons each half width of chat screen. i know the normal keyboard button there resize_keyboard parameter somehow can used. my question is there way resize inline buttons ? example make full width or quarter width. unfortunately, can't now. :( you can suggest @botsupport , might add feature next version.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
