Fixed bug #21228 (broken check for ob_gzhandler).
Fixed a bug that made ob_start return incorrect return value.

Comment about maximal length now matches code.

Merge streams changes from branch.

Fixed OnUpdate_zlib_output_compression() behaviour

Move wrong output buffer usage check to ob_gzhandler init.
Export some output buffer functions.

Revisted Wez patch: chunk_size 0 means cahce the whole output. So

Revisted Wez patch: chunk_size 0 means cahce the whole output. So
we must apply the default before calling php_enable_output_compression().
I have left the default setting in the rinit function even though i do think
it is not necessary.

Fix infinite recursion bug when using zlib output compression.
Cause: the chunk size is taken from the zlib.output_compression setting,
which is 0 or 1. This causes the block_size for output

Fix infinite recursion bug when using zlib output compression.
Cause: the chunk size is taken from the zlib.output_compression setting,
which is 0 or 1. This causes the block_size for output buffer to be set
to 0 (1 / 2) and thus causes infinite recursion in php_ob_allocate().
Solution: use a value of 0 for the chunk size which will use the default
sizes. Also add a sanity check which will default the block_size to 1
if it ends up as 0.

Use zend_ini_string instead of the 'alias'.

Fix ob_gzhandler()'s handling of requests w/o compression but that do have
the Accept-Encoding header

Fix error messages.

Fixed prototype.
Fixed double printing of function name in docref error messages.

change to php_error_docref()
#documentation about output relevant ini settings will be in ref.outcontrol

Changed handling of output buffer sizes.

Changed my mind.
Let users decided whether users want larger chunk size or not.
@ Changed zlib.output_compression behavior. If larger chunk is preferred,
enable output_buffering also. (

Generally speaking, sending packets less than 1KB is not efficient.
We're better to take some benchmarks see if removing extra buffer
is actually a good idea or not.

corrected handling of internal output buffers
minor fixs

no need to start additional first buffer when output compression is first buffer

should fix all windows warnings

Improved handling of output buffers (see news)\n#No trim for the string parameter...

Commit patch as discussed on LinuxTag and posted to php-dev in June.
Disables zlib.output_compression for scripts with image/ content-type
header (fixes bug #16109) and makes it possible to switch
zlib.output_compression during script execution before the headers are
sent.
@- zlib.output_compression is disabled for "image/" content-type
@ headers and can be changed during script execution. (Stefan)

- oops... read before commit :)

- It doesn't work from within a script... so we disallow it

Added "Vary: Accept-Encoding" header to zlib.output_compression
compressed output as with obgzhandler().

Added "Vary: Accept-Encoding" header to zlib.output_compression
compressed output as with obgzhandler().
@ If zlib.output_compression is enabled and a page is compressed
@ a "Vary: Accept-Encoding" header is added. (Stefan)
# obgzhandler() sends this header, I think it is recommened by
# RFC 2616. If there are problems (e.g. with some browsers)
# it should be reverted.

Move Content-Length: header handling from zlib.c to output.c
When output buffer is enabled and header can be sent, Content-Length:
header is added always from now on.

s/len/xln/ was necessary here
