Original Path: trunk 
Fall back to IPv4 when trying IPv6 for an IP socket fails due to a lack of
support.  But why is it Protocol not supported and not EPFNOSUPPORT!?
Revision 248 - Directory Listing
Modified Thu Aug 20 06:43:35 2009 UTC (12 months, 2 weeks ago) by juli
Original Path: trunk 
Push off on Pipes until 0.5.2, possibly.
Revision 247 - Directory Listing
Modified Thu Aug 20 06:40:43 2009 UTC (12 months, 2 weeks ago) by juli
Original Path: trunk 
o) Add the SocketAddressFamilyIP type which auto-detects IPv4 or IPv6.
o) Pass the address as a hint to Socket::create where applicable.
o) Make socket_address::operator() use getaddrinfo(3) to find an appropriate
   address in the desired family and to handle family inference when passed
   AF_UNSPEC.
o) Remember the socket type and numeric protocol to facilitate getaddrinfo(3).
o) Reorder Socket::create to make it possible to determine which IP family to
   use based on an address hint passed in.
o) While here make Socket::create's protocol argument default to empty.
o) Don't pass an empty protocol by hand to Socket::create for Unix domain
   sockets anymore.
o) Make the WANProxy default configuration use the IP address family and the
   "localhost" name so that it uses IPv4 or IPv6 as appropriate for that
   system.
Revision 246 - Directory Listing
Modified Thu Aug 20 05:33:09 2009 UTC (12 months, 2 weeks ago) by juli
Original Path: trunk 
Make encode_reference look more like encode_declaration.
Revision 245 - Directory Listing
Modified Thu Aug 20 00:37:32 2009 UTC (12 months, 2 weeks ago) by juli
Original Path: trunk 
Use a more efficient segment-sized copyout() invocation that might just create
a reference rather than copying if we're lucky.
Revision 244 - Directory Listing
Modified Thu Aug 20 00:33:57 2009 UTC (12 months, 2 weeks ago) by juli
Original Path: trunk 
Remove offset_seg_pair_t.
Revision 243 - Directory Listing
Modified Thu Aug 20 00:33:28 2009 UTC (12 months, 2 weeks ago) by juli
Original Path: trunk 
Factor out encode_declaration() and encode_reference() from the main encode() body.
Revision 242 - Directory Listing
Modified Thu Aug 20 00:08:11 2009 UTC (12 months, 2 weeks ago) by juli
Original Path: trunk 
Remove now-unused XCodecEncoder::Data class.
Revision 241 - Directory Listing
Modified Wed Aug 19 13:24:03 2009 UTC (12 months, 2 weeks ago) by juli
Original Path: trunk 
Rewrite the XCodecEncoder encode function...
o) Do the entirety of processing in the first loop rather than processing
   references and then declarations.  This improves handling of in-stream
   collisions and references to data earlier in a stream.
   XXX This duplicates a lot of code.  Add a TODO item to clean it up.
o) Correct an implementation bug: when we have a collision, we should still
   check to see whether the last-known-good hash should be declared.
o) As a result of merging the loops add logic to handle adjacent hash collisions
   (and hits) gracefully.

The net effect of this is that performance may be slightly degraded in terms of
encode throughput (merging the loops was at first a boost in throughput but
handling edge cases and better encoding possibilities ate the increase) the
compression ratio for non-random, non-uniform data is significantly better than
previously, from 1% to 10% better in some tested data sets.  Random data should
be the same and veryuniform data sees a significant performance boost from the
elimination of the second loop (both in terms of eliminating the number of loops
and in terms of registering declarations earlier) -- about twice the throughput
of the previous encoder.

Modified Thu Aug 13 00:14:54 2009 UTC (12 months, 3 weeks ago) by juli
Original Path: trunk 
Forcefully set the ConfigType pointer to NULL in case of failure sine GCC seems
to be confused about this in many versions.  XXX Would be nice to conditionalize

Revision 205 - Directory Listing
Modified Wed Aug 12 21:41:21 2009 UTC (12 months, 3 weeks ago) by juli

Revision 200 - Directory Listing
Modified Thu Aug 6 23:47:23 2009 UTC (13 months ago) by juli
Original Path: trunk 
Add compile-tested Unix domain socket support.  I'd like to make CLI<->WANProxy
use Unix domain sockets, and this also helps clarify how the Socket API and
implementation need to change to be more general.
Revision 199 - Directory Listing

Make accept virtual.

Modified Thu Jul 30 10:03:03 2009 UTC (13 months, 1 week ago) by juli
Original Path: trunk 
Record io's dependency on event and net's dependency on event and io.

XXX This approach is kind of ugly.  Perhaps just REQUIREMENTS or DEPENDENCIES
    or something and either make it hard to find out which library's requirement
    is unmet, or make it slightly less ugly at best, like, DEPENDENCIES+=io:net
    rather than IO_DEPENDENCIES+=net.  Almost better to just hard-code it.  But
    not quite.
Revision 190 - Directory Listing
Modified Thu Jul 30 09:58:09 2009 UTC (13 months, 1 week ago) by juli
Original Path: trunk

Revision 184 - Directory Listing
Modified Tue Jun 30 04:50:13 2009 UTC (14 months, 1 week ago) by juli
Original Path: trunk 
Remove FlowTables and the FlowMonitor since the new configuration format doesn't

Revision 177 - Directory Listing
Modified Tue Jun 16 03:09:11 2009 UTC (14 months, 3 weeks ago) by juli

Revision 176 - Directory Listing
Modified Tue Jun 16 00:11:41 2009 UTC (14 months, 3 weeks ago) by juli
Original Path: trunk 
We implicitly make <string> a part of the standard environment for WANProxy by
needing it in <common/log.h>, so be explicit and put it in <common/common.h> since
it's basically indispensible like the logging and debugging stuff.  This allows
me to clean up recent confusion I've introduced about this in the config code.
Revision 175 - Directory Listing
Modified Mon Jun 15 23:02:27 2009 UTC (14 months, 3 weeks ago) by juli

o) Add ZZCodec, which zig-zag transforms blocks of data.  This produces fewer

o) Make it okay for kqueue to return EINTR.
o) Only claim that a TimeoutQueue is not empty if at least one of its

   since items can be removed from those queues by a cancel, it's important to

o) Use typedefs for offset-hash and offset-seg pairs rather than spelling
   out the full template every time.
o) Don't leak a refernece to a BufferSegment if there's a first-pass
   collision.
o) Remove some comments from the block before the main encode function
   which are being replaced by inline comments reflecting where work can
   be done or where it has been done.  Namely:
o) Comment where we should be (first) caching the database_ presense, so we
   avoid having to search the giant hash when we already know the results in
   a more local context.
o) Don't add redundant possible-declarations to the offset-hash map.  Also
   note where it is possible to do declarations in the first pass without
   resorting to the second pass.

The last item results in a 30% performance boost (statistically significant)

o) Don't make XCodecSlice create more XCodecSlices, there's no need.  We've
   now well-encapsulated the child data, so create an XCodecSlice::Data
   struct to reflect that, much like xcodec_slice.
o) Make the children just a vector of XCodecSlice::Datas.
o) Make declarations_ a std::set since the Data will have a BufferSegment.
o) Get rid of the type_ of XCodecSlice now.
o) Hash all input, not all but the last XCODEC_SEGMENT_LENGTH.
o) Since we're no longer recursive, we can make decisions when outputting the
   references in encode()...
o) Copy the declarations_ set to a local variable called 'need_declared' in
   encode so that we can output declarations when they are referenced, and be
   sure to output them only once.  This restores locality of reference.  It
   also puts us back in the situation where we wonder if we need to make a
   DECLARE/HASHREF pair, or if we can have DECLARE imply HASHREF.

Write the new slice/encoder.

o) Track declarations needed by a slice and its children.
o) Look for redundant data using algorithms explained in the code.
o) Get rid of trying to slice the data up into smaller working units.  The
   only gains that gives are related to locality of reference, which is
   absolutely broken now, but likely to be fixed.

Performance is below that of the old encoder by a few times in the case of
data with a lot of redundancy, but it's probably fairly easy to fix that,
at least for some data sets.  Comments explain the plan-of-action and the
perceived problem space.

Random data performs about as well, it seems, in terms of streaming rate.

And even if performance is worse, that's to be expected since there's no
more crazy inlining, and probably a worthwhile trade-off since this version
of the encoder is humanly-comprehensible (and full of almost-useful
comments.)

Vastly improve the decoder despite keeping it mostly the same:
o) Be more tolerant of errors in the stream, and don't use exceptions
   to detect them.  Most importantly, don't crash because of them.
o) Keep track of the number of bytes in the input Buffer and use that
   to figure out how long to loop, etc., rather than looking into the
   Buffer all the time to figure out whether it's empty (and sometimes
   what its length is.)
o) Loop over un-escaped non-special data aggressively.  There's going to
   be some in every stream and we should process it well.
o) Don't leak segments in the event that some errors occur.

This translates into a slight performance increase (less slight with some
workloads), a huge reliability boost and a good chance to improve the
comments and clarity of the code.

o) Make the Event callback system no longer require a void * user data argument.
   Instead, provide two callback classes, one with a user-specified argument, one
   with none and one with an argument type specified by a template parameter.
   For now the only consumer of user-specified arguments still uses a void *.

o) Consolidate all of the decoder funcitons into the decode() function for now.
o) Add some DEBUG if we decode only some data due to there not being enough buffered
   to decode the current command.
o) Use the existing seg if we're trying to enter a sum that already exists (and is
   correct) in the database.

XXX Really should rewrite encoder and decoder at some point.  Or at least make it so
    the decoder fails more gracefully.

XXX I did this work in search of an infinite loop due to a ESCAPE at end of input.
    How did it get there!?  Is there an encoder bug?  Could not reproduce.

Original Path: trunk 
Close a race whereby:

	1) Channel X closes its file descriptor, N.
	2) An Event::Done for close is queued.
	3) A pending callback which creates a socket is called, which is given
	   file descriptor N, since it's free.  This would blow up since when
	   the channel attaches to the socket, N will be found to be in use by
	   the IOSystem.  Even if it didn't blow up:
	4) The Event::Done for the close is delivered, channel X detaches from
	   socket N and finds it is not closed anymore.

Do this by keying the IOSystem's Handle map with a std::pair of file descriptor
and Channel.  This may even allow for Channels to pass file descriptors to each
other if we get rid of the need to close before detach.

Original Path: trunk 
Add a singleton IOSystem which manages IO requests (close/read/write.)  It may
at some point use lio_listio or similar to batch up IO requests.  This moves
some code out of FileDescriptor.  It also means we have to remove some
assertions from Socket and FileDescriptor since they no longer have visibility
into close() calls.

Original Path: trunk 
Do as the XXX suggests and avoid starting the local peer until the remote peer
is connected.  Otherwise we would blow up when close_peer() is called while we
are still connecting to the remote peer.  Now, maybe the right thing to do is to
fix that case to work properly so we can buffer lots of data from a client that
is starting out with a lot of data, but really that's an uncommon case so for
now do the easy thing.

Revision 4 - Directory Listing
Modified Fri Feb 20 12:35:58 2009 UTC (18 months, 2 weeks ago) by juli
Original Path: trunk 
o) Add a parameter to Channel::read to take an amount to read, defaulting to 0,
   which retains the old behavior of reading whatever amount is available.
o) Implement new Channel::read semantics in FileDescriptor::read.  Add buffering
   to FileDescriptor.
   Note that this tries to only read the amount specified by the caller, which
   may not be most efficient, but may provide the right behavior in terms of
   not acknowledging data?
o) Add ugly hackish redundant APIs to support numeric IP addresses in addition
   to strings.
o) Use said ugly hackish API to implement a simple SOCKS4 proxy.  It's a very
   conservative proxy that tries to be discreet (in that it doesn't send errors
   to clients sending random requests.)
   XXX SOCKS5 would be nice.
o) Modify the default config to show chaining through to the SOCKS4 proxy.
