rtorrent 0.9.2-1 crashed upon start several times when I tried it
couple of weeks ago. (Today it did not crash yet, but this seems to be
the usual behavior when I am trying to reproduce crash for the bug
report.)
By the way, changes like this in libtorrent's configure look
suspicious:
int main() {
- struct kevent ev[2], ev_out[2];
+ struct kevent ev2, ev_out2;
struct timespec ts = { 0, 0 };
- int pfd[2], pty[2], kfd, n;
- char buffer[9001];
+ int pfd2, pty2, kfd, n;
+ char buffer9001;
if (pipe(pfd) == -1) return 1;
- if (fcntl(pfd[1], F_SETFL, O_NONBLOCK) == -1) return 2;
- while ((n = write(pfd[1], buffer, sizeof(buffer))) ==
sizeof(buffer));
- if ((pty[0]=posix_openpt(O_RDWR | O_NOCTTY)) == -1) return 3;
- if ((pty[1]=grantpt(pty[0])) == -1) return 4;
- EV_SET(ev+0, pfd[1], EVFILT_WRITE, EV_ADD | EV_ENABLE, 0, 0,
NULL);
- EV_SET(ev+1, pty[1], EVFILT_READ, EV_ADD | EV_ENABLE, 0, 0,
NULL);
+ if (fcntl(pfd1, F_SETFL, O_NONBLOCK) == -1) return 2;
+ while ((n = write(pfd1, buffer, sizeof(buffer))) ==
sizeof(buffer));
+ if ((pty0=posix_openpt(O_RDWR | O_NOCTTY)) == -1) return 3;
+ if ((pty1=grantpt(pty0)) == -1) return 4;
+ EV_SET(ev+0, pfd1, EVFILT_WRITE, EV_ADD | EV_ENABLE, 0, 0,
NULL);
+ EV_SET(ev+1, pty1, EVFILT_READ, EV_ADD | EV_ENABLE, 0, 0,
NULL);
if ((kfd = kqueue()) == -1) return 5;
if ((n = kevent(kfd, ev, 2, NULL, 0, NULL)) == -1) return 6;
- if (ev_out[0].flags & EV_ERROR) return 7;
- if (ev_out[1].flags & EV_ERROR) return 8;
- read(pfd[0], buffer, sizeof(buffer));
+ if (ev_out0.flags & EV_ERROR) return 7;
+ if (ev_out1.flags & EV_ERROR) return 8;
+ read(pfd0, buffer, sizeof(buffer));
+ if ((n = kevent(kfd, NULL, 0, ev_out, 2, &ts)) < 1) return 9;
+ return 0;
+ }
All brackets around array indexes are lost in c snippets.
My .rtorrent.rc contains this:
bind = …
port_range = …-…
#port_range = …-…
check_hash = yes
directory = "…"
http_proxy = ""
encoding_list = "utf-8"
encryption = allow_incoming,try_outgoing
peer_exchange = yes
session = "…"
dht = auto
dht_port = …
There are usually several dozens of torrents from jamendo in the session
directory.
