c - Why does the kretprobe of the _do_fork() only return once? -

when write small script fork, syscall returns twice processes (once per process): #include <stdio.h> #include <unistd.h> int main(int argc, char *argv[]) { int pid = fork(); if (pid == 0) { // child } else if (pid > 0) { // parent } } if instrument systemtap, find 1 return value: // fork() in libc calls clone on linux probe syscall.clone.return { printf("return clone\n") } ( systemtap installes probes on _do_fork instead of clone, shouldn't change anything.) this confuses me. couple of related questions: why syscall return once? if understand _do_fork code correctly, process cloned in middle of function. ( copy_process , wake_up_new_task ). shouldn't subsequent code run in both processes? does kernel code after syscall run in same thread / process user code before syscall? creation of child can fail, errors have detected , handled the child has different return value , has handled ...

i'm using spring's named queries access data , came upon issue. have rather long named query in spring data repo: list<landscapelocationentity> findbyidcustomeridandidproductgroupandidproductidandidlocationidinandactiveflag(string customerid, string productgroup, string productid, list<integer> locationid, boolean activeflag); the query works fine long provide list<integer> 1 entry. there entry throw java.sql.sqlexception: borrow preparestatement pool failed . as can see in screenshot, call different actual query (locationid(?,?) vs. locationid(?)). have workaround executes queries separately that's not way want have in long term. if need further information please tell me. update: prove point removed other attributes , still same error: query now: list<landscapelocationentity> findbyidlocationidin(list<integer> locations);

c - cat breaks the program, manual stdin input doesn't -

i have small program: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <sys/wait.h> int main() { int orig = 1; (int = 0; (i != 3) && orig; ++i) { orig = orig && fork(); } if (orig) { (int = 0; != 3; ++i) { wait(null); } } else { int num; scanf("%8d", &num); printf("%d\n", num*num); } } which supposed square 3 numbers reads stdin . , if type numbers in myself, works: akiiino$ ./out.out 12345678 12345678 12345678 260846532 260846532 260846532 but if use cat same purpose, not work expected: akiiino$ cat in.txt 12345678 12345678 12345678 akiiino$ cat in.txt | ./out.out 260846532 0 0 what reason behind weird behavior , fixable? i've assumed cat ing files no different typing them stdin . the difference when type 3 numbers by hand , reading terminal , low level reads terminated on newlines. let...

c++ - Using gRPC with MFC in a shared DLL gives memory leaks -

i integrating grpc in windows application uses third party libraries need mfc in shared dll vs2015. build multi-threaded dll (/md) version of libprotobuf.lib , grpc++.lib , helloworld example. when set use standard windows libraries helloworld server grpc example works fine. when set use mfc in shared dll helloworld server grpc example works, exits lot of memory leaks. dumping objects -> {1475} normal block @ 0x00000259f0cb9070, 22 bytes long. data: <g r p c _ t r > 47 00 52 00 50 00 43 00 5f 00 54 00 52 00 41 00 {1398} normal block @ 0x00000259f0cb7d70, 30 bytes long. data: <g r p c _ v e r > 47 00 52 00 50 00 43 00 5f 00 56 00 45 00 52 00 ... also running piece of code, not start server, gives memory leaks. looks static allocation in grpc code , not runtime issue. int main(int argc, char** argv) { //runserver(); return 0; } is grpc+mfc combination possible?
