directive is set in activation time). This commit fixes this by adding a per
request parsing of the browscap file that's when get_browser is called the
first time and the directive is set on activation time.w
This reverts the fix for bug #24557.
- Make php_stream_free delete the stream from the resources list, not merely
decrease its refcount, as a single call to zend_list_delete does.
#Not worth the risk merging to 5.3. While change #2 may prevent some segfaults,
#a quick and dirty survey to the codebase only showed calls to php_stream_close
#or php_stream_free on streams allocated in the same function, which would have
#refcount == 1. May be reconsidered.

#php_stream->wrapperdata should hold an array zval (like its zval* type

- PHP_STREAM_OPTION_WRITE_BUFFER no longer changes the chunk size in socket
streams.
- Added stream_set_chunk_size() function.
- Some signedness fixes.
- Test for commit r308474, now that it's possible to actually test it.

The tests that fail due to #308035 in the standard ext were not

desirable one, both this commit and #308035 ought to be reverted
or at least adapted.

headers_list(), header_remove() and header() can all be used

- Fixed usage of zend_multibyte_get_internal_encoding (its return cannot be
cast to char*).
- Change tests to reflect that charset detection now relies on
internal_encoding, not on current_internal_encoding.
NOTE: This fixes the changes in rev 306077, but it remains that that change
introduced a BC break. I assumed it was intentional
- Added mechanism to force outer streams to be closed before their inner ones.
- Fixed temp:// streams only handling correctly (through an ad hoc mechanism) reverse closing order
when the inner stream is of type memory.

- Moved ext/standard/tests/file/htmlentities19.phpt and htmlspecialchars.phpt to the
proper directory (tests/strings instead of tests/file). htmlentities19.phpt had to
be renamed in order not to clash with an existing file.

remains.
- Fixed bug on determine_charset that was preventing correct detection in
combination with internal mbstring encoding "none", "pass" or "auto".
- Added profiles for entity encode/decode for HTMl 4.01, XHTML 1.0, XML 1.0
and HTML 5. Added the constants ENT_HTML401, ENT_XML1, ENT_XHTML and
ENT_HTML5.
- htmlentities()/htmlspecialchars(), when told not to double encode, verify
the correctness of the existenting entities more thoroughly.
It is checked whether the numerical entity represents a valid unicode code
point (number is between 0 and 0x10FFFF). If using the flag ENT_DISALLOWED,
it is also checked whether that numerical entity is valid in selected
document. In HTML 4.01, all the numerical entities that represent a Unicode
code point (< U+10FFFFFF) are valid, but that's not the case with other
document types. If the entity is not valid, & is encoded to &.
For named entities, the check is also more thorough. While before the only
check would be to determine if the entity was constituted by alphanumeric
characters, now it is checked whether that entity is necessarily defined for
the target document type. Otherwise, & is encoded to &.
- For html_entity_decode(), only valid numerical and named entities (as defined
above for htmlentities()/htmlspecialchars() + !double_encode) are decoded.
But there is in this case one additional check. Entities that represent
non-SGML or otherwise invalid characters are not decoded. Note that, in
HTML5, U+000D is a valid literal character, but the entity 
 is not
valid and is therefore not decoded.
- The hash tables lazily created for decoding in html_entity_decode() that were
added recently were substituted by static hash tables. Instead of 1 hash
table per encoding, there's only one hash table per document type defined in
terms of unicode code points. This means that for charsets other than UTF-8
and ISO-8859-1, a conversion to unicode code points is necessary before
decoding.
- On the encoding side, the ad hoc ranges of entities of the translation
tables, which mapped (in general) non-unicode code points to HTML entities
were replaced by three-stage tables for HTML 4 and HTML 5. This mapping
tables are defined only in terms of unicode code points, so a conversion
is necessary for charsets other than UTF-8 and ISO-8859-1. Even so, the
multi-stage table is much faster than the previous method, by a factor
of 5; the conversion to unicode is a small penalty because it's just a
simple table lookup.
XML 1.0/htmlspecialchars() uses a simple table instead of a three-stage
table.
- Added the flag ENT_SUBSTITUTE, which makes htmlentities()/htmlspecialchars()
replace the invalid multibyte sequences with U+FFFD (UTF-8) or &#FFFD;
(other encodings).
- Added the flag ENT_DISALLOWED. Implements FR #52860. Characters that cannot
appear literally are replaced by U+FFFD (UTF-8) or &#FFFD; (otherwise).
An alternative implementation would be to encode those characters into
numerical entities, but that would only work in HTML 4.01 due to limitations
on the values of numerical entities in other document types. See also the
effects on htmlentities()/htmlspecialchars() with !double_encode above.
fix the erratic behavior without breaking backwards compatibility. Namely,
$offset retains SEEK_SET behavior but actually SEEK_CUR is passed to
_php_stream_seek, if possible, by moving the offset stream->position bytes.
- Addresses bug #53006.
