c++ - explicit operator bool not called inside lambda — MSVC bug? - 


#include <functional>  struct t {     explicit operator bool() { return true; } };  int main() {     t t;      if(t) {} // ok      auto l = [&]() {         if (t) {} // error     }; }

msvc's behaviour seems oddly inconsistent here; difference between ok line , error line 1 in lambda. bug?

is bug?

yes, definitely. there nothing wrong in program, bool conversion operator shall invoked in both cases.

Java sticky instances of class com.mysql.jdbc.Field aggregating -

i noticed (via jmap+jhat) app leaking storing many instances com.mysql.jdbc.field  class - double checked code make sure closing preparedstatements, find few missing didn't change outcome. - preparedstatement created , closed right away - several others created @ start , reused many times - using org.apache.tomcat.jdbc.pool.datasource connection pool what can cause type of behavior? are closing of preparedstatements / result sets using: preparedstatement stmt (possible assignment here); try { // work prepared statement resultset rs; try { while (rs.next()) ... // process results } { rs.close(); } } { stmt.close(); } so guarantee result sets closed when finished (regardless of exceptions) , statements closed (regardless of exceptions)? there other ways write that, idea same. if you're doing of properly, unless have many references it's taking inordinate amount of memory, it's ok , nothing needs done it.
