1. A lock which is not self-latching, but requires a key to
throw the bolt forward.
[1913 Webster]
2. A counteraction of things, which produces an entire
stoppage; a complete obstruction of action.
[1913 Webster]
Things are at a deadlock. --London
Times.

n 1: a situation in which no progress can be made or no
advancement is possible; "reached an impasse on the
negotiations" [syn: deadlock, dead end, impasse,
stalemate, standstill] |
deadlock
(foldoc) | deadlock
deadly embrace
A situation where two or more
processes are unable to proceed because each is waiting for
one of the others to do something.
A common example is a program waiting for output from a server
while the server is waiting for more input from the
controlling program before outputting anything. It is
reported that this particular flavour of deadlock is sometimes
called a "starvation deadlock", though the term "starvation"
is more properly used for situations where a program can never
run simply because it never gets high enough priority.
Another common flavour is "constipation", in which each
process is trying to send stuff to the other but all buffers
are full because nobody is reading anything). See {deadly
embrace}.
Another example, common in database programming, is two
processes that are sharing some resource (e.g. read access to
a table) but then both decide to wait for exclusive
(e.g. write) access.
The term "deadly embrace" is mostly synonymous, though usually
used only when exactly two processes are involved. This is
the more popular term in Europe, while deadlock predominates
in the United States.
Compare: livelock. See also safety property, {liveness
property}.

deadlock
(jargon) | deadlock
n.
1. [techspeak] A situation wherein two or more processes are unable to
proceed because each is waiting for one of the others to do something. A
common example is a program communicating to a server, which may find
itself waiting for output from the server before sending anything more to
it, while the server is similarly waiting for more input from the
controlling program before outputting anything. (It is reported that this
particular flavor of deadlock is sometimes called a starvation deadlock,
though the term starvation is more properly used for situations where a
program can never run simply because it never gets high enough priority.
Another common flavor is constipation, in which each process is trying to
send stuff to the other but all buffers are full because nobody is reading
anything.) See deadly embrace.
2. Also used of deadlock-like interactions between humans, as when two
people meet in a narrow corridor, and each tries to be polite by moving
aside to let the other pass, but they end up swaying from side to side
without making any progress because they always move the same way at the
same time.
