* Fix a hard-to-trigger memory leak in launch_resolve•••To hit this leak, you need to be a relay that gets a RESOLVE request or an exit node getting a BEGIN or RESOLVE request. You must either have unconfigured (and unconfigurable) nameservers, or you must have somehow set DisableNetwork after a network request arrived but before you managed to process it. So, I doubt this is reached often. Still, a leak's a leak. Fix for bug 5916; bugfix on 0.2.3.9-alpha and 0.1.2.1-alpha. Nick Mathewson2012-05-18
* Use the standard _WIN32, not the Torism MS_WINDOWS or deprecated WIN32•••This commit is completely mechanical; I used this perl script to make it: #!/usr/bin/perl -w -i.bak -p if (/^\s*\#/) { s/MS_WINDOWS/_WIN32/g; s/\bWIN32\b/_WIN32/g; } Nick Mathewson2012-01-31

* Use SOCKET_OK macros in even more places•••Add a TOR_INVALID_SOCKET macro to wrap -1/INVALID_SOCKET. Partial work for bug4533. Nick Mathewson2012-01-17
* Make sure we never launch an evdns resolve when DisableNetwork is 1Nick Mathewson2011-11-29
* Change "reverse_lookup_name" functions to refer to "PTR_name"s•••Under the new convention, having a tor_addr.*lookup function that doesn't do hostname resolution is too close for comfort. I used this script here, and have made no other changes. s/tor_addr_parse_reverse_lookup_name/tor_addr_parse_PTR_name/g; s/tor_addr_to_reverse_lookup_name/tor_addr_to_PTR_name/g; Nick Mathewson2011-10-11
* Fix names of functions that convert strings to addrs•••Now let's have "lookup" indicate that there can be a hostname resolution, and "parse" indicate that there wasn't. Previously, we had one "lookup" function that did resolution; four "parse" functions, half of which did resolution; and a "from_str()" function that didn't do resolution. That's confusing and error-prone! The code changes in this commit are exactly the result of this perl script, run under "perl -p -i.bak" : s/tor_addr_port_parse/tor_addr_port_lookup/g; s/parse_addr_port(?=[^_])/addr_port_lookup/g; s/tor_addr_from_str/tor_addr_parse/g; This patch leaves aton and pton alone: their naming convention and behavior is is determined by the sockets API. More renaming may be needed. Nick Mathewson2011-10-11
* Make the get_options() return const•••This lets us make a lot of other stuff const, allows the compiler to generate (slightly) better code, and will make me get slightly fewer patches from folks who stick mutable stuff into or_options_t. const: because not every input is an output!

| * Fix check for failed evdns request creation•••When using libevent 2, we use evdns_base_resolve_*(). When not, we fake evdns_base_resolve_*() using evdns_resolve_*(). Our old check was looking for negative values (like libevent 2 returns), but our eventdns.c code returns 1. This code makes the check just test for nonzero. Note that this broken check was not for _resolve_ failures or even for failures to _launch_ a resolve: it was for failures to _create_ or _encode_ a resolve request.

This gains us consistence for our free functions, and allows some code simplifications where an explicit null check is no longer necessary. Sebastian Hahn2009-12-12

* | Fix a crash when using evdns from Libevent 2.•••When we tried to use the deprecated non-threadsafe evdns interfaces in Libevent 2 without using the also-deprecated event_init() interface, Libevent 2 would sensibly crash, since it has no guess where to find the Libevent library. Here we use the evdns_base_*() functions instead if they're present, and fake them if they aren't. Nick Mathewson2009-10-13

* | Isolate Libevent API dependency to just main.c and dns.c in src/or.•••The rest of the code was only including event.h so that it could see EV_READ and EV_WRITE, which we were using as part of the connection_watch_events interface for no very good reason. Nick Mathewson2009-06-12
* | Update Tor to use Libevent 2.0 APIs when available.•••This patch adds a new compat_libevent.[ch] set of files, and moves our Libevent compatibility and utilitity functions there. We build them into a separate .a so that nothing else in src/commmon depends on Libevent (partially fixing bug 507). Also, do not use our own built-in evdns copy when we have Libevent 2.0, whose evdns is finally good enough (thus fixing Bug 920). Nick Mathewson2009-06-12
