2018-06-20Update copyrights to 2018.Nick Mathewson
2018-05-10Add functions to enable/disable periodic_event_t objects.Nick Mathewson
2018-04-26Remove the "cached gettimeofday" logic.Nick Mathewson
Previously were using this value to have a cheap highish-resolution timer. But we were only using it in one place, and current dogma is to use monotime_coarse_t for this kind of thing.
2018-04-13Generic mechaism for "post-loop" callbacksNick Mathewson
We've been labeling some events as happening "outside the event loop", to avoid Libevent starvation. This patch provides a cleaner mechanism to avoid that starvation. For background, the problem here is that Libevent only scans for new events once it has run all its active callbacks. So if the callbacks keep activating new callbacks, they could potentially starve Libevent indefinitely and keep it from ever checking for timed, socket, or signal events. To solve this, we add the ability to label some events as "post-loop". The rule for a "post-loop" event is that any events _it_ activates can only be run after libevent has re-scanned for new events at least once.
2018-04-05Wrap the function we use to run the event loop.Nick Mathewson
Doing this lets us remove the event2/event.h header from a few more modules, particularly in the tests. Part of work on 23750.
2018-04-05Add wrappers for event_base_loopexit and event_base_loopbreak.Nick Mathewson
2018-04-05Add an API for a scheduled/manually activated event in the mainloopNick Mathewson
Using this API lets us remove event2/event.h usage from half a dozen modules, to better isolate libevent. Implements part of ticket 23750.
2018-04-02Remove event2/event.h include from compat_libevent.hNick Mathewson
Only one module was depending on this include (test_helpers.c), and it was doing so incorrectly.
2017-12-11On exit, free the event_base and set its pointer to NULL.Nick Mathewson
When we didn't do this before, we'd have some still-reachable memory warnings, and we'd find ourselves crashing when we tried to reinitialize libevent. Part of 24581 (don't crash when restarting Tor in-process)
2017-12-08Fix wide lines introduced by previous patch.Nick Mathewson
2017-12-08Replace all FREE_AND_NULL* uses to take a type and a free function.Nick Mathewson
This commit was made mechanically by this perl script: \#!/usr/bin/perl -w -i -p next if /^#define FREE_AND_NULL/; s/\bFREE_AND_NULL\((\w+),/FREE_AND_NULL\(${1}_t, ${1}_free_,/; s/\bFREE_AND_NULL_UNMATCHED\(/FREE_AND_NULL\(/;
2017-12-08Switch to a safer FREE_AND_NULL implementationNick Mathewson
This one only evaluates the input once, so it cannot mess up even if there are side effects.
2017-12-08Convert the rest of src/common's headers to use FREE_AND_NULLNick Mathewson
2017-10-20Expose a new function to make the event loop exit once and for all.Nick Mathewson
Instead of calling tor_cleanup(), exit(x), we can now call tor_shutdown_event_loop_and_exit.
2017-09-15Run our #else/#endif annotator on our source code.Nick Mathewson
2017-05-10In channelpadding tests that touch libevent, call event_reinit().Nick Mathewson
This is necessary to avoid crashes and test failures on kevent-based systems. Fixes bug 22209; bug not in any released Tor.

2016-08-02Search for remaining references to 'bufferevent'.Nick Mathewson
Remove or adjust as appropriate.
2016-08-02Bufferevent removal: remove more bufferevent-only optionsNick Mathewson
(All this IOCP stuff was bufferevent-only.)
2016-08-02Remove USE_BUFFEREVENTS code outside src/orNick Mathewson
2016-07-19Remove tor_gettimeofday_cached_monotonic as broken and unneededNick Mathewson
2016-07-04Address review comments from cypherpunksSebastian Hahn
2016-07-04Raise libevent dependency to 2.0.10-stable or newerSebastian Hahn
Only some very ancient distributions don't ship with Libevent 2 anymore, even the oldest supported Ubuntu LTS version has it. This allows us to get rid of a lot of compat code.
2016-02-27Update the copyright year.Nick Mathewson
2015-10-02Clean up compat_libevent testsNick Mathewson
2015-09-15Add tests for compat_libeventOla Bini
2015-03-12Remove workarounds for Libevent < 1.3.Nick Mathewson
This actually lets us dump a lot of old cruft that nobody had (I hope!) tested in ages. Closes 15248.
2015-01-12src/common/compat_libevent.h: include testsupport.hAnthony G. Basile
When tor is configured with --enable-bufferevents, the build fails because compat_libevent.h makes use of the macro MOCK_DECL() which is defined in testsupport.h, but not included. We add the include.

2014-10-28Add another year to our copyright dates.Nick Mathewson
Because in 95 years, we or our successors will surely care about enforcing the BSD license terms on this code. Right?

2014-08-29Always event_del() connection events before freeing themNick Mathewson
Previously, we had done this only in the connection_free() case, but when we called connection_free_() directly from connections_free_all(), we didn't free the connections.
2014-04-16Get Libevent's PRNG functioning under the linux sandboxNick Mathewson
Libevent uses an arc4random implementation (I know, I know) to generate DNS transaction IDs and capitalization. But it liked to initialize it either with opening /dev/urandom (which won't work under the sandbox if it doesn't use the right pointer), or with sysctl({CTL_KERN,KERN_RANDOM,RANDOM_UUIC}). To make _that_ work, we were permitting sysctl unconditionally. That's not such a great idea. Instead, we try to initialize the libevent PRNG _before_ installing the sandbox, and make sysctl always fail with EPERM under the sandbox.

2014-02-26Monotonize the OOM-killer data timersNick Mathewson
In a couple of places, to implement the OOM-circuit-killer defense against sniper attacks, we have counters to remember the age of cells or data chunks. These timers were based on wall clock time, which can move backwards, thus giving roll-over results for our age calculation. This commit creates a low-budget monotonic time, based on ratcheting gettimeofday(), so that even in the event of a time rollback, we don't do anything _really_ stupid. A future version of Tor should update this function to do something even less stupid here, like employ clock_gettime() or its kin.

2012-10-12Convert all include-guard macros to avoid reserved identifiers.Nick Mathewson
In C, we technically aren't supposed to define our own things that start with an underscore. This is a purely machine-generated commit. First, I ran this script on all the headers in src/{common,or,test,tools/*}/*.h : ============================== use strict; my %macros = (); my %skipped = (); FILE: for my $fn (@ARGV) { my $f = $fn;

next; } if ($macros{$fn} !~ /_H_?$/) { print "# Weird macro for $fn...\n"; } my $goodmacro = uc $fn; $goodmacro =~ s#.*/##; $goodmacro =~ s#[\/\-\.]#_#g; print "s/(?<![A-Za-z0-9_])$macros{$fn}(?![A-Za-z0-9_])/TOR_${goodmacro}/g;\n" } ============================== It produced the following output, which I then re-ran on those same files: ============================== s/(?<![A-Za-z0-9_])_TOR_ADDRESS_H(?![A-Za-z0-9_])/TOR_ADDRESS_H/g;

Also, try to resolve some doxygen issues. First, define a magic "This is doxygen!" macro so that we take the correct branch in various #if/#else/#endifs in order to get the right documentation. Second, add in a few grouping @{ and @} entries in order to get some variables and fields to get grouped together.
