Why gdb switched to home directory? -


suppose current directory /home/xxx/test, there text file named "test.txt" contains single word "hello", , file named "test.cpp" following,

#include <iostream> #include <fstream> #include <unistd.h> using namespace std;  int main () {         char cwd[1024];         getcwd(cwd, 1024);         cout << cwd << endl;          string s;         ifstream i("test.txt");         if (!i.good())                 cout << "can't open test.txt" << endl;          >> s;         i.close();          cout << s << endl;          return 0; }  test> g++ test.cpp test> ./a.out /home/xxx/test hello test> gdb a.out gnu gdb (gdb) red hat enterprise linux (7.2-60.el6_4.1) copyright (c) 2010 free software foundation, inc. license gplv3+: gnu gpl version 3 or later <http://gnu.org/licenses/gpl.html> free software: free change , redistribute it. there no warranty, extent permitted law.  type "show copying" , "show warranty" details. gdb configured "x86_64-redhat-linux-gnu". bug reporting instructions, please see: <http://www.gnu.org/software/gdb/bugs/>... reading symbols /home/xxx/test/a.out...(no debugging symbols found)...done. (gdb) run starting program: /home/xxx/test/a.out /home/xxx can't open test.txt   program exited normally. (gdb) pwd working directory /home/xxx/test. (gdb) shell pwd /home/xxx

my question why gdb switched home directory yields 'test.txt' can't found? why 'pwd' , 'shell pwd' give different result?

thanks.

there 'cd ~' in .cshrc, root cause difference between 'shell pwd' , 'pwd'.

after remove it, problems resolved.

thanks.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
