18,043,512 | 0 | <p>It is almost impossible to answer your question in the scope of a SO "answer" - you will need to read up on implementation of parallel processing for the particular architecture of your machine if you want the "real" answer. Short answer is "it depends". But your program could be running on both processors, on any or all of the four cores; they key to understand here is that you can control that to some extent with the structure of your program, but the neat thing about OMP is that usually "you ought not to care". If threads are operating concurrently, they will usually get a core each; but if they need to access the same memory space that may slow you down since "short term data" likes to live in the processor's (core's) cache, and that means there is a lot of shuffling data going on. You get the greatest performance improvements if different threads DON'T have to share memory.</p> |

I've been using it for months and I'm very satisfied.</p> <p>If you're worried about the future of your app you should consider that Nodemailer is used not just with Sendgrid, but with a lot of other competitors.

But some customers who have Android 4.0 complain me that it doesn't work! It returns something like mac-address: fe80::fad0:bdff:fe4d:4871 Can anyone explain what's happened?</p> <p>The second problem is about WiFi checking state. I use function below to check connection to WiFi hotspot point:</p> <pre><code> public boolean IsWiFiConnected(){ List<WifiConfiguration> wifiConfigList = wifiManager.getConfiguredNetworks(); boolean retVal=false; for(WifiConfiguration wifiConf : wifiConfigList){ if(wifiConf.status==WifiConfiguration.Status.CURRENT){ retVal=true; break; } } return retVal; } </code></pre> <p>In android 4.0 it always returns false. </p> <p>And the third problem is getting device's information (it happens on ASUS Transformer Prime): I get information about device by using function below:</p> <pre><code>public static String GetDeviceInfo(Context context){ TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); return Build.BRAND.toString()+"~|~"+Build.DEVICE.toString()+"~|~"+telephonyManager.getDeviceId().toString()+"~|~"+Build.VERSION.RELEASE; } </code></pre> <p>It throws NULLPointerExeption.

Some of the ways we have used Virtualization:</p> <ul> <li>Virtualized complete .NET development environment in Windows XP, including VS 2008, IIS, MS SQL Server</li> <li>Virtualized complete PHP + RoR development environment in CentOS</li> <li>Virtualized multiple complete Java environments in Windows XP, including Eclipse, Tomcat / Jboss, MySQL and Apache</li> <li>Virtualized multiple complete server environments (with GUI's) in Server 2003, Server 2008, Ubuntu, CentOS, Red Hat, and openSUSE.</li> </ul> <p>In your case, I would say virtualize the entire desktop, then clone it so you can run multiple instances on which you can try your different variations of gem packages, plugins, and configurations. If your host machine has enough RAM -- at least 4GB, you should be able to run at least 3 instances needing 1GB of RAM each.

34,503,110 | 0 | cmocka malloc testing OOM and gcov <p>I'm having a hard time finding an answer to a nitch case using cmocka, testing malloc for failure (simulating), and using gcov</p> <p>Update about cmocka+gcov: I noticed I get empty gcda files as soon as I mock a function in my cmocka tests. Why? Googling cmocka and gcov gives results where people talk about using the two together. It seems most people are using CMake, something I will look at later but there should be no reason (that I can think of) that would require me to use cmake. Why can't I just use cmocka with the --coverage/-lgcov flags?</p> <p>Orignal question:</p> <p>I've tried a myriad combinations mostly based off of two main ideas:</p> <p>I tried using -Wl,--wrap=malloc so calls to malloc are wrapped. From my cmocka tests I attempted to use will_return(__wrap_malloc, (void*)NULL) to simulate a malloc failure. In my wrap function I use mock() to determine if I should return __real_malloc() or NULL. This has the ideal effect, however I found that gcov fails to create gcda files, which is part of the reason with wrapping malloc, so I can test malloc failing AND get code coverage results. I feel I've played dirty games with symbols and messed up malloc() calls called form other compilation units (gcov? cmocka?).</p> <p>Another way I tried was to us gcc -include using a #define for malloc to call "my malloc" and compile my target code to be tested with mymalloc.c (defining the "my malloc"). So a #define malloc _mymalloc helps me call only the "special malloc" from the target test code leaving malloc alone anywhere else it is called (i.e., leave the other compilation unites alone so they just always call real malloc). However I don't know how to use will_return() and mock() correctly to detect failure cases vs success cases. If I am testing malloc() failing I get what I want, I return NULL from "malloc" based on mock() returning NULL- this is all done in a wrapping function for malloc that is only called in the targeted code. However if I want to return the results of the real malloc than cmocka will fail since I didn't return the result from mock(). I wish I could just have cmocka just dequeue the results from the mock() macro and then not care that I didn't return the results since I need real results from malloc() so the code under test can function correctly.</p> <p>I feel it should be possible to combine malloc testing, with cmocka and get gcov results.</p> <p>whatever the answer is I'd like to pull of the following or something similar.</p> <pre><code>int business_code() { void* d = malloc(somethingCalculated); void* e = malloc(somethingElse); if(!d) return someRecovery(); if(!e) return someOtherRecovery(); return 0; } </code></pre> <p>then have cmocka tests like</p> <pre><code>cmocka_d_fail() { will_return(malloc, NULL); int ret = business_code(); assert_int_equal(ret, ERROR_CODE_D); } cmocka_e_fail() { will_return(malloc, __LINE__); // someway to tell wrapped malloc to give me real memory because the code under test needs it will_return(malloc, NULL); // I want "d" malloc to succeed but "e" malloc to fail int ret = business_code(); assert_int_equal(ret, ERROR_CODE_E); } </code></pre> <p>I get close with some of the #define/wrap ideas I tried but in the end I either mess up malloc and cause gcov to not spit out my coverage data or I don't have a way to have cmocka run malloc cases and return real memory i.e., not reeturn from mock() calls. On one hand I could call real malloc from my test driver but and pass that to will_return but my test_code doesn't know the size of the memory needed, only the code under test knows that.</p> <p>given time constraints I don't want to move away from cmocka and my current test infrastructure. I'd consider other ideas in the future though if what I want isn't possible. What I'm looking for I know isn't new but I'm trying to use a cmocka/gcov solution.</p> <p>Thanks</p> |
