* Hide the contents of the circuit_build_times structure.•••There were only two functions outside of circuitstats that actually wanted to know what was inside this. Making the structure itself hidden should help isolation and prevent us from spaghettifying the thing more. Nick Mathewson2013-08-22
* Separate mutable/const accessors for circuit_build_times•••(These have proved invaluable for other global accessors.) Nick Mathewson2013-08-22
* Make circ_times static and add accessor functions.•••Change the global circ_times to a static variable and use accessor functions throughout the code, instead of accessing it directly. vagrant2013-08-22

| | * Implement a real OOM-killer for too-long circuit queues.•••This implements "algorithm 1" from my discussion of bug #9072: on OOM, find the circuits with the longest queues, and kill them. It's also a fix for #9063 -- without the side-effects of bug #9072. The memory bounds aren't perfect here, and you need to be sure to allow some slack for the rest of Tor's usage. This isn't a perfect fix; the rest of the solutions I describe on codeable. Nick Mathewson2013-06-18
* | | Add destroy balance tracking and logging to circuitmuxAndrea Shepard2013-06-13
* | | Implementation of a fix for bug 7912•••I added the code to pass a destroy cell to a queueing function rather than writing it immediately, and the code to remember that we shouldn't reuse the circuit id until the destroy is actually sent, and the code to release the circuit id once the destroy has been sent... and then I finished by hooking destroy_cell_queue into the rest of Tor.

| * | | Rename circuit_expire_all_dirty_circs•••The new name is circuit_mark_all_dirty_circs_as_unusable. This resolves an XXX024 Nick Mathewson2013-02-19
| * | | Stop frobbing timestamp_dirty as our sole means to mark circuits unusable•••In a number of places, we decrement timestamp_dirty by MaxCircuitDirtiness in order to mark a stream as "unusable for any new connections. This pattern sucks for a few reasons: * It is nonobvious. * It is error-prone: decrementing 0 can be a bad choice indeed. * It really wants to have a function. It can also introduce bugs if the system time jumps backwards, or if MaxCircuitDirtiness is increased. So in this patch, I add an unusable_for_new_conns flag to origin_circuit_t, make it get checked everywhere it should (I looked for things that tested timestamp_dirty), and add a new function to frob it. For now, the new function does still frob timestamp_dirty (after checking for underflow and whatnot), in case I missed any cases that should be checking unusable_for_new_conns. Fixes bug 6174. We first used this pattern in 516ef41ac1fd26f338c, which I think was in 0.0.2pre26 (but it could have been 0.0.2pre27). Nick Mathewson2013-02-19

* | | Fix 8447: use %u to format circid_t.•••Now that circid_t is 4 bytes long, the default integer promotions will leave it alone when sizeof(int) == 4, which will leave us formatting an unsigned as an int. That's technically undefined behavior. Fixes bug 8447 on bfffc1f0fc7616a25c32da2eb759dade4651659e. Bug not in any released Tor. Nick Mathewson2013-03-10

I've gone with the safest possible replacement, which might be a bit slow. I don't think this is critical path in any way that will affect performance, but if it is, we can work on that in 0.2.4.

* | Rename all reserved C identifiers we defined•••For everything we declare that starts with _, make it end with _ instead. This is a machine-generated patch.

Then pipe the output through this script: ============================== use strict; BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; } chomp; next if ( /^__attribute__/ or /^__func__/ or /^_FILE_OFFSET_BITS/ or /^_FORTIFY_SOURCE/ or /^_GNU_SOURCE/ or /^_WIN32/ or /^_DARWIN_UNLIMITED/ or /^_FILE_OFFSET_BITS/ or /^_LARGEFILE64_SOURCE/ or /^_LFS64_LARGEFILE/ or /^__cdecl/ or /^__attribute__/ or /^__func__/ or /^_WIN32_WINNT/); my $ident = $_; my $better = $ident; $better =~ s/^_//; $better = "${better}_"; print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n"; ============================== Then run the resulting script on all the files you want to change.
