* ZMQ_REQ_STRICT was negative option (default 1) which goes against
the standard, where defaults are zero. I renamed this to
ZMQ_REQ_RELAXED.
* ZMQ_REQ_REQUEST_IDS felt clumsy and describes the technical solution
rather than the problem/requirement. I changed to ZMQ_REQ_CORRELATE
which seems more explicit.
- tests that system can provide at least 1,000 sockets
- we could expand on this but this covers the main case of OS/X
having a too-low default limit of 256 handles per process
- Split off NULL security check from PLAIN
- Cleaned up test_linger code a little
- Got all tests to pass, added TODOs for outstanding issues
- Added ZAP authentication for NULL test case
- NULL mechanism was not passing server identity - fixed
- cleaned up test_security_plain and removed option double-checks (made code ugly)
- lowered timeout on expect_bounce_fail to 150 msec to speed up checks
- removed all sleeps from test_fork and simplified code (it still passes :-)
This allows making a new request on a REQ socket by sending a new
message. Without the option set, calling send() after the first message
is done will continue to return an EFSM error.
It's useful for when a REQ is not getting a response. Previously that
meant creating a new socket or switching to DEALER.
* Documentation:
The default behavior of REQ sockets is to rely on the ordering of messages
to match requests and responses and that is usually sufficient. When this option
is set to 1, the REQ socket will prefix outgoing messages with an extra frame
containing a request id. That means the full message is (request id, 0,
user frames...). The REQ socket will discard all incoming messages that don't
begin with these two frames.
* Behavior change: When a REQ socket gets an invalid reply, it used to
discard the message and return EAGAIN. REQ sockets still discard
invalid messages, but keep looking at the next one automatically
until a good one is found or there are no more messages.
* Add test_req_request_ids.
* disabled the specific tests that do not work (yet) on libzmq
* cleaned up one source (test_spec_rep.c) but the others need similar work
* added sleep in test_spec_rep to allow connects time to happen; this would
not be needed if we connected out to the REP peers instead in from them,
but I didn't want to change the logic of the test code.

This patch, salvaged from a trainwreck accidental merge earlier, adds a
new sockopt, ZMQ_DELAY_ATTACH_ON_CONNECT which prevents a end point
being available to push messages to until it has fully connected, making
connect work more like bind. This also applies to reconnecting sockets,
which may cause message loss of in-queue messages, so it is sensible to
use this in conjunction with a low HWM and potentially an alternative
acknowledgement path.
Notes on most of the individual commits can be found the repository log.
This patch adds a sockopt ZMQ_DELAY_ATTACH_ON_CONNECT, which if set to 1 will attempt to preempt this behavior. It does this by extending the use of the session_base to include in the outbound as well as the inbound pipe, and only associates the pipe with the socket once it receives the connected callback via a process_attach message. This works, and a test has been added to show so, but may introduce unexpected complications. The shutdown logic in this class has become marginally more awkward because of this, requiring the session to serve as the sink for both pipes if shutdown occurs with a still-connecting pipe in place. It is also possible there could be issues around flushing the messages, but as I could not directly think how to create such an issue I have not written any code with regards to that.
The documentation has been updated to reflect the change, but please do check over the code and test and review.
These include configurations for both Win32 and x64 platforms. All project
settings have been normalised in property sheets (the ".props" files under
builds/msvc/properties) to simplify maintenance. Build artefacts are all
generated in platform-specific subfolders of bin, lib and obj directories.
Also enables the use of precompiled headers with MSVC10.
This significantly reduces the time required to compile libzmq with Visual
Studio on Windows. It should have no impact on other platforms.

Mercurial does not have built-in support for converting line-endings. This is a
settings file for hg eol (http://mercurial.selenic.com/wiki/EolExtension), an
extension that replicates the behaviour of git with core.autocrlf=true.
Mercurial uses Python regex syntax by default in its .hgignore files. Adding
this line to .gitignore overrides that setting, so hg-git users can just create
a hardlink to it (e.g "mklink /H .hgignore .gitignore" on Windows) to use it.
