Master port stores two file descriptors and works as a read port on the master
process side. After a fork, the port switches into write mode and the read
socket closes, but the same event structure is used for the write socket.
However, the inherited structure remained in read state, telling the epoll
engine to use MOD operation instead of ADD. The patch resets read event
state, so the engine may write using proper ADD operation.

Absence of this flag is the reason of memory leak in case when client
disconnected before receiving all response data.

This is required to assemble fragmented messages correctly. Stream
identifier is unique only for messages generated within a process, but
the (stream, pid) pair should be enough to avoid collisions. Adding
reply_port seems redundant because it's enough to add stream to a pid.
This closes #199 issue on GitHub.

Sending large plain (exceeding port's max_size, not in shared memory) messages
causes message fragmentation. First message fragment is sent successfully,
but the next fragment may fail with the EAGAIN error. In this case, the
message has to be pushed back to queue head for additional processing.
Related to #167 issue on GitHub.

Unlike EAGAIN, ENOBUFS returned on OSX when trying to send many relatively
small (64 bytes) fragments.
Found during investigation of #167 issue on GitHub.
|
|
Before this fix, large plain message (i.e. configuration) send may fail
with the 'Message too big' error, because internal fragmentation
implementation does not account for 16 byte message header.
This closes #167 issue on GitHub.

After event is delivered from the kernel its further processing is blocked.
Non-ready TSL I/O operation should mark connection I/O state as not ready
to unblock events and to allow their further processing. Otherwise
the connection hangs.

According to CGI/1.1 RFC 3875:
The server MUST set this variable; if the Script-URI does not include a
query component, the QUERY_STRING MUST be defined as an empty string ("").
Python's PEP 333(3) allows omitting it in WSGI interface; PHP docs force no
requirements; PSGI and Rack specifications require it even if empty.
When nginx proxies requests over FastCGI, it always provides QUERY_STRING.
and some PHP apps have been observed to fail if it is missing (see issue
#201 on GitHub).
A drawback of this change (besides a small overhead) is that there will be
no easy way to tell a missing query string from an empty one (i.e. requests
with or without the "?" character); yet, it's negligible compared to the
possible benefits of wider application compatibility.
This closes #226 issue on GitHub.

When idle timeout occurs at the same time as a request comes in,
the timer handler closes connection while the read event triggers
request processing, and this eventually leads to segmentation fault.

As far as I understand, this field is important to control the number of
buffers send in a single write attempt. Furthermore, having uninitialized
field is always bad.

This patch contains various logging improvements and bugfixes found
during Java module development.
|
|
This message produces too many noise in log and complicates analysis.

Fragmented message non-mmap buffer chain not freed nor reused before
this fix.

Also, increased default select() timeout from 1s to 5s.
|
|
Also minor header organizing.
|

The application can return the body as an IO:Handle-like object
without file descriptor.

While it looks nicer without zero 3-rd version number, this should
improve interoperability. Version string can be parsed or used for
sorting. And it is easier to handle and less confusing when there
is constant number of version parts.
Moreover, NPM also expects version format with 3 parts.
So ".0" has already been used in Node.js module version.

Previously, the nxt_router_prepare_msg() function expected server host among
other headers unmodified. It's not true anymore since normalization of the
Host header has been introduced in 77aad2c142a0.
The nxt_unit_split_host() function was removed. It didn't work correctly with
IPv6 literals. Anyway, after 77aad2c142a0 the port splitting is done in router
while Host header processing.
