Changes

0.28

	- Released at 2019-01-11T16:25:00+0900
	- Now the distribution is made with mbtiny.
	- Various improvements of the test suite.
	- Rewrite the internally-used testing-purpose HTTP server to allow the control of 'Content-Length' request header.

0.27

	- Released at 2016-10-28T12:59:00+0100
	- Unbreak with Elasticeasrch 5.0. See https://rt.cpan.org/Public/Bug/Display.html?id=118425

0.26

	- Released at 2015-11-25T12:30:00+0100
	- No functional changes since 0.25, but we had some Travis-specific
	  changes in the repo, releasing just so we have the latest code there
	  on the CPAN.

0.25

	- Released at 2015-11-25T12:20:00+0100

	- Make the t/select-timeout.t test which fails on various odd
	  CPANtesters platforms a TODO. Maybe some OS-specific issue, maybe an
	  issue with kill() in the CPANtesters sandboxes not behaving as we
	  expect.

0.24

	- Released at 2015-07-05T13:40:00+0200

	- Minor copyediting and formatting changes to the documentation. No
	  code changes at all.

0.23

	- Released at 2015-07-03T17:00:00+0200

	- The "Host" header can now be overriden by supplying a new
	  `no_default_host_header` option along with a `Host` header in `head
	  => []` to request().

	  Before this we'd always send "Host: $host" over, where $host was the
	  host we were connecting to, now you can customize this.

	- Fixed a bug where if passed passed `head => []` to request() we'd
	  emit a ":" header, i.e. just an empty header name with an empty
	  value.

	  You could have just not passed the `head => ` value if the array was
	  empty, but no we won't screw up and emit a single line consisting of
	  ":" if given an empty array.

0.22

	- Released at 2015-05-27T07:54:17+0200
	- No feature change. Re-package due to a missing file in the tarball:
	  https://rt.cpan.org/Ticket/Display.html?id=104624

0.21

	- Released at 2015-05-22T15:26:23+0200

	- Fix "Too many CRLF" issue. Hijk has been always generating HTTP
	  request with an extra CRLF at the end. While many HTTP servers are
	  ignoring those, some treat it as errors. We now eliminate the extra
	  CRLF at the end of every request.
	  See also http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html

	- Handle better when select() is interrupted by signals.

0.20

	- Released at 2015-03-20-T15:10:00+0000
	- Fix a regression in 0.14. When the chunked encoding support was
	  introduced we accidentally stopped supporting "Content-Length: 0",
	  treat those responses as the zero-body again. This broke e.g. PUT
	  requests that would return no payload.

	- Add support for 204 No Content responses. According to the HTTP
	  standard we must try to consume the body if there's no
	  Content-Length, but not if the server returns a 204 response, then
	  it MUST NOT include a body (see
	  http://tools.ietf.org/html/rfc2616#page-60).

	  This re-adds support for e.g. 204 No Content response, in practice
	  this "worked" before 0.14, but only accidentally and other types of
	  responses wouldn't work.

	- We now handle our system calls returning EINTR.

0.19

	- Released at 2015-01-10-T18:30:00+0000
	- Fix a major regression in 0.16. The introduction of "head_as_array"
	  completely broke the disconnection logic when the socket_cache was
	  enabled (which is the default). When talking to a webserver that
	  would disconnect us after N requests request N+1 would always fail
	  with a 0 byte response error.

	  This issue was reported as RT #101424
	  (https://rt.cpan.org/Public/Bug/Display.html?id=101424)

	- Fix a minor regression in 0.16: The introduction of "head_as_array"
	  broke the "proto" part of the return value in a relatively obscure
	  edge case where we'd read the header & had no Content-Length and
	  couldn't read() anything.

	- Fix an edge case in the Trailer support. It would only kick in if we
	  got the Transfer-Encoding header before the "Trailer" header, not
	  the other way around.

0.18

	- Released at 2014-12-10T14:00:00+000
	- We now do the right thing on "method => 'HEAD'". I.e. ignore the
	  Content-Length parameter, previously we'd just hang trying to slurp
	  up the body.
	- Fix an edge case with some of the live tests leaving around a HTTP
	  server if they died, these don't run by default.

0.17

	- Released at 2014-08-31T18:30:00+000
	- Minor documentation changes, no functional changes.
	- The version number for the last release was incorrect in this
	  changelog, fixed in this release.

0.16

	- Released at 2014-08-31T00:10:00+000
	- Major Change: There are several new Hijk::Error::* constants for
	  common issues that happened during normal requests in the face of
	  regular exceptions out of the control of this library, such as
	  network blips.

	  Existing code that checks $res->{error} should be
	  forwards-compatible with this change, but anything that was doing
	  e.g. regex checks against regular errors thrown by this library
	  should be updated to check the new Hijk::Error::* constants instead.

	- It's now possible to specify "head_as_array" to get the returned
	  headers as an array (with potential duplicated headers), rather than
	  the default behavior of lossily returning them as a hash.

	- There's now a "read_length" option to control how much we
	  POSIX::read($fd, $buf, $read_length) at a time. We don't expect this
	  to be useful, it's mainly configurable on general principle so we
	  don't have arbitrary unconfigurable hardcoded constants in the
	  source.

0.15

	- Released at 2014-08-30T10:00:00+000
	- The new code to support chunked transfer encoding would return a
	  nonexisting Hijk::Error::* value of "0" when it encountered a read
	  timeout. This meant that not only was the error reporting broken,
	  but anything checking if there were errors via the simple idiom of
	  "if ($res->{error}) {...}" wouldn't properly report errors.

	  We'll now correctly report these errors as
	  Hijk::Error::READ_TIMEOUT.

	- Since there may still be other bugs like that in this new parsing
	  mode it's disabled by default, if you know you want to parse chunked
	  responses you have to pass parse_chunked => 1 for now. Usually you
	  probably just want to disable chunked encoding on the other end, see
	  the note about how to do that with nginx in the docs.

0.14

	- Released at 2014-08-29T15:40:36+0900
	- Start support chunked transfer encoding.

0.13

	- Released at 2014-04-27T20:00:43+0200
	- Switch to use non-blocknig fd to avoid a rare deadlock situation
	  when select() is successful and the following read() blocks forever
	  because there are really nothing to read.

0.12

	- Released at 2014-01-31T18:20:00+0100
	- Instead of dying on e.g. "Bad arg length for
	  Socket::pack_sockaddr_in, length is 0, should be 4" when given a
	  host we can't resolve we'll now return a $res with the error value
	  set to Hijk::Error::CANNOT_RESOLVEif we can't gethostbyname() the
	  provided hostname. Makes it easier to handle DNS resolution
	  failures.

0.11

	- Released at 2014-01-06T13:20:00+0100
	- Fixed broken HTTP header parsing for servers that didn't return the
	  entire header all at the same time, but in chunks.
	- We now return "proto" as well as "status" etc. in the response, so
	  you can see what the protocol the server was using to speak to
	  us. Also we pro-actively connections to servers that claim they're
	  speaking HTTP/1.0.
	- Document that what the socket_cache is keyed on, for anyone wanting
	  to implement a tied hash or whatever.
	- Fix a minor bug causing redundant work under "socket_cache => undef"

0.10

	- Released at 2013-12-19T16:50:00+0100
	- We can now talk HTTP/1.0 an addition to HTTP/1.1, have a way to
	  disable the socket cache, and can specify connect and read timeouts
	  independently.
	- Fix a really nasty bug with mixings up requests after encountering a
	  timeout. See
	  http://lists.unbit.it/pipermail/uwsgi/2013-December/006802.html for
	  details.
	- Remove spurious requirenment on perl v5.14.2
	- First stab at https://github.com/gugod/Hijk/issues/3 we'll now
	  return an error key in the response with
	  Hijk::Error::{CONNECT_TIMEOUT,READ_TIMEOUT} instead of dying.
	- Nuked the Hijk::HTTP::XS support from the repo, we've decided it was
	  too complex for its own good.
	- Add support for an on_connect callback for seeing how long the
	  connect/reads take.

0.09

	- Released at 2013-12-13T07:38:25+0100
	- KEEP CALM AND REMOVE FETCH OPTION
	- Hijk::request will use XS parser only if Hijk::HTTP::XS is loaded

0.08

	- Released at 2013-12-12T20:10:00+0100
	- We only checked for undefined return codes from POSIX::read(), not
	  0, resulting in an infinite select/read loop when a server with
	  keep-alive enabled cut off our connection.

0.07

	- Released at 2013-12-09T12:50:00+0100
	- Skip the live connect timeout test by default, it will fail making
	  live connections on various firewalled/locked down hosts.

0.06

	- Released at 2013-12-09T12:20:00+0100
	- Declare missing test dependency on Test::Exception
	- Declare test dependency on Net::Ping 2.41
	- Various POD improvements describing more limitations in the API and
	  providing examples.
	- Don't unconditionally load the yet-to-be-released Hijk::HTTP::XS
	  module, instead provide a "fetch" option.
	- Shutdown and delete the cached connection in case of read error.
	- Handle syswrite() returning undef without spewing an uninitialized
	  comparison error
	- Various work on the test suite.
