This "publish/subscribe" layer sits on top of lib/dispatch, and
tries to provide more type-safety and cross-checking for the
lower-level layer.
Even with this commit, we're still not done: more checking will come
in the next commit, and a set of usability/typesafety macros will
come after.
This module implements a way to send messages from one module to
another, with associated data types. It does not yet do anything to
ensure that messages are correct, that types match, or that other
forms of consistency are preserved.
We already do this in our log_debug() macro, but there are times
when we'd like to avoid allocating or precomputing something that we
are only going to log if debugging is on.
Previously, or_connection_t did not record whether or not the
connection uses a pluggable transport. Instead, it stored the
underlying proxy protocol of the pluggable transport in
proxy_type. This made bootstrap reporting treat pluggable transport
connections as plain proxy connections.
Store a separate bit indicating whether a pluggable transport is in
use, and decode this during bootstrap reporting.
Fixes bug 28925; bugfix on 0.4.0.1-alpha.
When NULL is given to lpApplicationName we enable Windows' "magical"
path interpretation logic, which makes Tor 0.4.x behave in the same way
as previous Tor versions did when it comes to executing binaries in
different system paths.
For more information about this have a look at the CreateProcessA()
documentation on MSDN -- especially the string interpretation example is
useful to understand this issue.
This bug was introduced in commit bfb94dd2ca.

The name of circpad_machine_state_t was very confusing since it was conflicting
with circpad_state_t and circpad_circuit_state_t.
Right now here is the current meaning of these structs:
circpad_state_t -> A state of the state machine.
circpad_machine_runtime_t -> The current mutable runtime info of the state machine.
circpad_circuit_state_t -> Circuit conditions based on which we should apply a machine to the circuit
so that the relays that would be "excluded" from the bandwidth
file because of something failed can be included to diagnose what
failed, without still including these relays in the bandwidth
authorities vote.
Closes#29806.
This is something we should think about harder, but we probably want dormant
mode to be more powerful than padding in case a client has been inactive for a
day or so. After all, there are probably no circuits open at this point and
dormant mode will not allow the client to open more circuits.
Furthermore, padding should not block dormant mode from being activated, since
dormant mode relies on SocksPort activity, and circuit padding does not mess
with that.
