RFC - Program to schedule download of winetest.exe

[Jakob Eriksson]

I have hacked together a little program to download winetest.exe and run
it every 24h.

Here is the URL:

http://vmlinux.org/jakov/Wine/testloader/

There are more binaries and stuff there too.

I know this is not a windows service, but at least it is something. Keep 
this
console aplication open and it will download winetest.exe every 24h, with
some randomness, to go easy on the server.

.----------------------------------.

What the code looks like:

#include <string>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
#include <windows.h>
#include <io.h>
#include <process.h>

using namespace std;

static void await(int hour)
{
    int right_time = 0;
    do {
        time_t now = time(NULL);
        struct tm comp = *gmtime(&now);
        if (comp.tm_hour == hour) {
            Sleep((rand()%60) * 60000); // Introduce randomness
            right_time = 1;
        } else {
            Sleep(10000);
        }
    } while(!right_time);
}

#define WINETESTS "winetests.exe"
#define TESTCOPY "testcopy.exe"

static void runtest()
{
    SetCurrentDirectory(getenv("TEMP"));

_unlink(WINETESTS);

system("wget --no-clobber http://vmlinux.org/jakov/Wine/" WINETESTS);

// Validate GPG signature for winetest.exe -- TODO

// silly wget makes file not executable
    if (!CopyFile(WINETESTS, TESTCOPY, FALSE)) {
        printf("Problem with file " WINETESTS "\n");

return;
    }

_unlink(WINETESTS);
    rename(TESTCOPY, WINETESTS);

printf("execl %s returns: %d\n", WINETESTS, _execl(WINETESTS, 
WINETESTS, NULL));
}

int main(int argc, char **argv)
{
    int run_once = 0;

if (argc != 2) {
        printf("Usage:\n%s < hour_of_download | once >\n", argv[0]);

return 0;
    }

srand((unsigned int)time(NULL));

if (2 == argc) {
        if (string(argv[1]) == "once") {
            run_once = 1;
        }
    }

if (run_once) {
        runtest();

return 0;
    }

while (1) {
        await(atoi(argv[1]));
        runtest();
    }

return 0;
}
