Nick Mathewson 8a85239746 Add a helper function to decrement read and write at the same time 2018-04-13 10:41:14 -04:00
Nick Mathewson c376200f6a Add a new token-bucket backend abstraction, with tests 
This differs from our previous token bucket abstraction in a few
ways:

  1) It is an abstraction, and not a collection of fields.
  2) It is meant to be used with monotonic timestamps, which should
     produce better results than calling gettimeofday over and over.
 2018-04-13 10:41:14 -04:00
Nick Mathewson d8ef9a2d1e Expose a function that computes stamp units from msec. 
(It turns out we can't just expose STAMP_TICKS_PER_SECOND, since
Apple doesn't have that.)

David Goulet 395fa0258d compat: Fix unchecked return value from event_del()

Nick Mathewson 6a5f62f68f Move responsibility for threadpool reply-handler events to workqueue 
This change makes cpuworker and test_workqueue no longer need to
include event2/event.h.  Now workqueue.c needs to include it, but
that is at least somewhat logical here.
 2018-04-05 12:36:28 -04:00
Nick Mathewson b3586629c9 Wrap the function we use to run the event loop. 
Doing this lets us remove the event2/event.h header from a few more
modules, particularly in the tests.

Part of work on 23750.
 2018-04-05 12:36:27 -04:00
Nick Mathewson 39cb04335f Add wrappers for event_base_loopexit and event_base_loopbreak. 2018-04-05 12:36:05 -04:00
Nick Mathewson f0d2733b46 Revise procmon.c to use periodic_timer_t 
This removes its need to use event2/event.h, and thereby fixes
another instance of 23750.
 2018-04-05 12:35:11 -04:00
Nick Mathewson 871ff0006d Add an API for a scheduled/manually activated event in the mainloop 
Using this API lets us remove event2/event.h usage from half a dozen
modules, to better isolate libevent.  Implements part of ticket
23750.
 2018-04-05 12:35:11 -04:00
Nick Mathewson f4bcf3f34c Remove event2/event.h include from compat_libevent.h 
Only one module was depending on this include (test_helpers.c), and
it was doing so incorrectly.

Nick Mathewson d4bf1f6c8e Add a paranoia check in string_is_valid_nonrfc_hostname() 
The earlier checks in this function should ensure that components is
always nonempty.  But in case somebody messes with them in the
future, let's add an extra check to make sure we aren't crashing.
 2018-03-28 07:48:18 -04:00
Nick Mathewson b504c854d3 Rename string_is_valid_hostname -> string_is_valid_nonrfc_hostname 
Per discussion on 25055.

Folks have found two in the past week or so; we may as well fix the
others.

Fernando Fernandez Mancera 0fad49e1c4 Move crypto_pk_obsolete_* functions into RSA module. 
We moved the crypto_pk_obselete_* functions into crypto_rsa.[ch] because they fit
better with the RSA module.

Follows #24658.

Nick Mathewson a34fc1dad2 Allow checkpointing of non-sha1 digests. 
This is necessary because apparently v3 rendezvous cpath hops use
sha3, which I had forgotten.

Bugfix on master; bug not in any released Tor.
