It is asn1, and the type of\n\/\/ PKCS #7 ContentInfo, which comprises the PKCS #7 structure, is:\n\/\/\n\/\/\t\t\tContentInfo ::= SEQUENCE {\n\/\/\t\t\t\tcontentType ContentType,\n\/\/\t\t\t\tcontent [0] EXPLICIT ANY DEFINED BY contentType OPTIONAL\n\/\/\t\t\t}\n\/\/\n\/\/ There are 6 possible ContentTypes, data, signedData, envelopedData,\n\/\/ signedAndEnvelopedData, digestedData, and encryptedData.

The ExtendedCertificatesAndCertificates type consists of a sequence of choices\n\/\/ between PKCS #6 extended certificates andx509 certificates.

The following trace is NOT a deadlock, but will be\n\t\/\/ reported as a deadlock on systems that consider only process granularity:\n\t\/\/\n\t\/\/ \tP.1 locks file A.\n\t\/\/ \tQ.3 locks file B.\n\t\/\/ \tQ.3 blocks on file A.\n\t\/\/ \tP.2 blocks on file B. (This is erroneously reported as a deadlock.)\n\t\/\/ \tP.1 unlocks file A.\n\t\/\/ \tQ.3 unblocks and locks file A.\n\t\/\/ \tQ.3 unlocks files A and B.\n\t\/\/ \tP.2 unblocks and locks file B.\n\t\/\/ \tP.2 unlocks file B.\n\t\/\/\n\t\/\/ These spurious errors were observed in practice on AIX and Solaris in\n\t\/\/ cmd\/go: see https:\/\/golang.org\/issue\/32817.\n\t\/\/\n\t\/\/ We work around this bug by treating EDEADLK as always spurious. If there\n\t\/\/ really is a lock-ordering bug between the interacting processes, it will\n\t\/\/ become a livelock instead, but that's not appreciably worse than if we had\n\t\/\/ a proper flock implementation (which generally does not even attempt to\n\t\/\/ diagnose deadlocks).\n\t\/\/\n\t\/\/ In the above example, that changes the trace to:\n\t\/\/\n\t\/\/ \tP.1 locks file A.\n\t\/\/ \tQ.3 locks file B.\n\t\/\/ \tQ.3 blocks on file A.\n\t\/\/ \tP.2 spuriously fails to lock file B and goes to sleep.\n\t\/\/ \tP.1 unlocks file A.\n\t\/\/ \tQ.3 unblocks and locks file A.\n\t\/\/ \tQ.3 unlocks files A and B.\n\t\/\/ \tP.2 wakes up and locks file B.\n\t\/\/ \tP.2 unlocks file B.\n\t\/\/\n\t\/\/ We know that the retry loop will not introduce a *spurious* livelock\n\t\/\/ because, according to the POSIX specification, EDEADLK is only to be\n\t\/\/ returned when “the lock is blocked by a lock from another process”.\n\t\/\/ If that process is blocked on some lock that we are holding, then the\n\t\/\/ resulting livelock is due to a real deadlock (and would manifest as such\n\t\/\/ when using, for example, the flock implementation of this package).\n\t\/\/ If the other process is *not* blocked on some other lock that we are\n\t\/\/ holding, then it will eventually release the requested lock.\n\n\tnextSleep := 1 * time.Millisecond\n\tconst maxSleep = 500 * time.Millisecond\n\tfor {\n\t\terr = setlkw(f.Fd(), lt)\n\t\tif err != syscall.EDEADLK {\n\t\t\tbreak\n\t\t}\n\t\ttime.Sleep(nextSleep)\n\n\t\tnextSleep += nextSleep\n\t\tif nextSleep > maxSleep {\n\t\t\tnextSleep = maxSleep\n\t\t}\n\t\t\/\/ Apply 10% jitter to avoid synchronizing collisions when we finally unblock.\n\t\tnextSleep += time.Duration((0.1*rand.Float64() - 0.05) * float64(nextSleep))\n\t}\n\n\tif err != nil {\n\t\tunlock(f)\n\t\treturn &os.PathError{\n\t\t\tOp:   lt.String(),\n\t\t\tPath: f.Name(),\n\t\t\tErr:  err,\n\t\t}\n\t}\n\n\treturn nil\n}\n\nfunc unlock(f File) error {\n\tvar owner File\n\n\tmu.Lock()\n\tino, ok := inodes[f]\n\tif ok {\n\t\towner = locks[ino].owner\n\t}\n\tmu.Unlock()\n\n\tif owner != f {\n\t\tpanic(\"unlock called on a file that is not locked\")\n\t}\n\n\terr := setlkw(f.Fd(), syscall.F_UNLCK)\n\n\tmu.Lock()\n\tl := locks[ino]\n\tif len(l.queue) == 0 {\n\t\t\/\/ No waiters: remove the map entry.\n\t\tdelete(locks, ino)\n\t} else {\n\t\t\/\/ The first waiter is sending us their file now.\n\t\t\/\/ Receive it and update the queue.\n\t\tl.owner = <-l.queue[0]\n\t\tl.queue = l.queue[1:]\n\t\tlocks[ino] = l\n\t}\n\tdelete(inodes, f)\n\tmu.Unlock()\n\n\treturn err\n}\n\n\/\/ setlkw calls FcntlFlock with F_SETLKW for the entire file indicated by fd.\nfunc setlkw(fd uintptr, lt lockType) error {\n\tfor {\n\t\terr := syscall.FcntlFlock(fd, syscall.F_SETLKW, &syscall.Flock_t{\n\t\t\tType:   int16(lt),\n\t\t\tWhence: io.SeekStart,\n\t\t\tStart:  0,\n\t\t\tLen:    0, \/\/ All bytes.\n\t\t})\n\t\tif err != syscall.EINTR {\n\t\t\treturn err\n\t\t}\n\t}\n}\n\nfunc isNotSupported(err error) bool {\n\treturn err == syscall.ENOSYS || err == syscall.ENOTSUP || err == syscall.EOPNOTSUPP || err == ErrNotSupported\n}\n<|endoftext|>"}
