We use random numbers for file names, both temporary filename when creating a zip for divelogs.de upload and for filename on form data for facebook upload. This does not require for true randomness but we still want these to not be constant on each run of Subsurface. Thus we need to initialize the random number generator.
Signed-off-by: Miika Turkia <[email protected]> --- I noticed this when I was testing the divelogs.de upload. I always ended up with same file name when removing the deletion of the temporary .dld. And of course I had problems adding the same files again to the already existing zip. --- subsurface-desktop-main.cpp | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/subsurface-desktop-main.cpp b/subsurface-desktop-main.cpp index d084f2a..2b7bf89 100644 --- a/subsurface-desktop-main.cpp +++ b/subsurface-desktop-main.cpp @@ -64,6 +64,14 @@ int main(int argc, char **argv) #else git_libgit2_init(); #endif + /* + * Initialize the random number generator - not really secure as + * this is based only on current time, but it should not matter + * that much in our context.
