Modified Thu Aug 20 07:00:39 2009 UTC (12 months, 2 weeks ago) by juli

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 247 - Directory Listing
Modified Thu Aug 20 06:40:43 2009 UTC (12 months, 2 weeks ago) by juli

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 229 - Directory Listing
Modified Sat Aug 15 10:07:21 2009 UTC (12 months, 3 weeks ago) by juli

o) Add a cat-like (well, not really) program that passes its stdin to its stdout
   via a PipeNull and which is useful for benchmarking the event system, IO,
   Pipe, Buffer, etc. (about 10% of cat(1) right now), and which clearly
   illustrates the need for a way to signal EOF to a Pipe and to get EOS back
   from one.

---

Revision 227 - Directory Listing
Modified Sat Aug 15 08:42:16 2009 UTC (12 months, 3 weeks ago) by juli

Turn some HALTs into ERRORs.

---

Revision 215 - Directory Listing
Modified Thu Aug 13 06:53:01 2009 UTC (12 months, 3 weeks ago) by juli

o) Move Socket{AddressFamily,Type} enums to new <io/socket_types.h> for
   consumers of the types but not the Socket API.
o) Make the configuration system use the SocketAddressFamily instead of its own
   hand-rolled thing.
o) Make the Unix client/server API ask for the SocketType since that can vary,
   but the SocketAddressFamily is implicit.
o) Make TCP* and UDP* API ask for the SocketAddressFamily.  The rest is implied.
o) Modify a test so that it will be possible to sneak IPv6 into it RSN.

---

Revision 214 - Directory Listing
Modified Thu Aug 13 06:16:52 2009 UTC (12 months, 3 weeks ago) by juli

Put hostnames in brackets, just to be sure.

---

Revision 206 - Directory Listing
Modified Wed Aug 12 23:05:12 2009 UTC (12 months, 3 weeks ago) by juli

o) Switch to single-string connect() and bind().
o) Make ports strings.
o) Use getsockname() to construct the listening address if bind() with
   port of 0, rather than passing in a pointer to the port, simplifying
   the API for non-0 code.
o) Add getsockname() pass-through to TCPServer.

---

Revision 203 - Directory Listing

---

Revision 200 - Directory Listing
Modified Thu Aug 6 23:47:23 2009 UTC (13 months ago) by juli

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 197 - Directory Listing

Blow up nicely if the Buffer * passed to write() is empty, instead of blowing

Revision 191 - Directory Listing
Modified Thu Jul 30 10:03:03 2009 UTC (13 months, 1 week ago) by juli

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 179 - Directory Listing
Modified Sat Jun 27 09:21:33 2009 UTC (14 months, 1 week ago) by juli

Move program.mk into common/ to make tab-completion of programs/ less ugly and

Mention switching to getnameinfo(3).

---

Revision 129 - Directory Listing
Modified Sat Apr 18 04:05:51 2009 UTC (16 months, 2 weeks ago) by juli

o) Set OSNAME in program.mk rather than in each library that needs it.
o) If running OpenBSD, disable -Werror, since OpenBSD has an ancient compiler
   that bogusly warns about private destructors without any defined friends.

---

Revision 128 - Directory Listing
Modified Sat Apr 18 01:23:26 2009 UTC (16 months, 2 weeks ago) by juli

Make everything build on OpenSolaris.
o) Include <errno.h> in cases where the extern definition of errno may be
   needed, in addition to <sys/errno.h>.
o) Remove serial interface support code, it has not been needed and will not
   likely be needed in the WANProxy repository.
o) On SunOS, add -lnsl and -lsocket when using IO routines as networking
   support requires them.
o) On SunOS, like on Linux, do not populate a 'len' field of a socket address.
o) Mark a bad assertion with a comment.
o) Don't use gethostbyname2(3) on SunOS, sigh.  Would be good to write a
   simple non-blocking resolver anyway...
o) Attempt to use the SunOS method of endianness-determination at compile
   time.  Hopefully I got that right.

Revision 127 - Directory Listing

Revision 112 - Directory Listing
Modified Fri Mar 27 07:50:58 2009 UTC (17 months, 1 week ago) by juli

Fix build with GCC 4.4, note some flags that may be useful in the future, etc.
Instead of including common/log.h and common/debug.h on the command line, just
include common/common.h, and let that include headers that are globally-desired,
namely stdint stuff and common/log.h and common/debug.h.  Elsewhere, include
headers that are required at least with GCC 4.4 at least in GNU++0x mode to get
certain functions and constants to be visible.

Revision 106 - Directory Listing

Add a UDPClient.

---

Revision 64 - Directory Listing
Modified Sun Mar 15 02:51:49 2009 UTC (17 months, 3 weeks ago) by juli

o) Don't use bsd.prog.mk where bsd.subdir.mk is desired.
o) Make TCPClient just give the user a Socket.  There's no reason they
   would want to have to go through some silly wrapper class.
o) Get rid of a warning in file.cc by returning NULL if HALT()<< for
   some incomprehensible reason doesn't return.  I hate GCC.
o) Make TCPClient::connect ASSERT that it can get a Socket rather than
   having it return NULL, since nobody checks its return value anyway.
o) Make program.mk not rely on bsd.prog.mk (just bsd.obj.mk.)
o) Crank up warnings a bit.

Revision 55 - Directory Listing
Modified Thu Mar 12 04:09:25 2009 UTC (17 months, 3 weeks ago) by juli

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 *.

Revision 51 - Directory Listing
Modified Sat Mar 7 04:38:41 2009 UTC (18 months ago) by juli

o) Make it possible to get the underlying Socket from a TCPClient.
o) Add getpeername() and getsockname() to Socket, returning strings.
o) Handle EOS in ProxySocksConnection for when a client goes away before
   it finishes authenticating and connecting outwards.
o) Add a FlowTable structure for registering flows.
o) Parameterize proxy listeners and such with a FlowTable.
o) Make ProxyClient manage flow table entries.
o) Pass Sockets around rather than Channels where we want to be able to
   do things like getpeername()/getsockname().
o) Fix WANProxyConfig log handle.
o) Create a FlowMonitor which reports on flow table entries.
o) Add flow-monitor and flow-table commands to start a FlowMonitor and to
   create FlowTables.
o) Make proxies specify which FlowTable their clients go into.

Revision 38 - Directory Listing
Modified Thu Mar 5 02:05:02 2009 UTC (18 months ago) by juli

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.

Comment a race I noticed last night.

Revision 36 - Directory Listing
Modified Wed Mar 4 09:13:44 2009 UTC (18 months ago) by juli

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.

Revision 33 - Directory Listing

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.
