To perform fast shutdown without full table cleanup we need all
internal functions to be in one continuous chunk. This was
violated when functions were deleted via disable_functions.
This drops the zend_disable_function() API in favor of
zend_disable_functions(), which disables the given list of
functions and performs the necessary rehash afterwards.
Also drop PG(disabled_functions), which is no longer used.
Voidification of Zend API which always succeeded
Use bool argument types instead of int for boolean arguments
Use bool return type for functions which return true/false (1/0)
Use zend_result return type for functions which return SUCCESS/FAILURE as they don't follow normal boolean semantics
Closes GH-6002
We might just want to drop this completely, but at least don't
enable it by default. It already gets disabled by a number of
SAPIs, but we should make that the default state.
Unconditionally strip shebang lines when using the CLI SAPI,
independently of whether they occur in the primary or non-primary
script. It's unlikely that someone intentionally wants to print
that shebang line when including a script, and this regularly
causes issues when scripts are used in multiple contexts, e.g.
for direct invocation and as a phar bootstrap.
Add a `zend.exception_string_param_max_len` ini setting.
(same suffix as `log_errors_max_len`)
Allow values between 0 and 1000000 bytes.
For example, with zend.exception_string_param_max_len=0,
"" would represent the empty string, and "..." would represent something
longer than the empty string.
Previously, this was hardcoded as exactly 15 bytes.

This makes the zend_error_cb API simpler, and avoid formatting
the same message in multiple places.
It should be noted that the passed zend_string is always
non-persistent, so if you want to store it persistently somewhere,
you may still need to duplicate it.
The last_error_message is cleared a bit more aggressive, to make
sure it doesn't hang around across allocator life-cycles.
Closes GH-5639.
It should be noted that we still throw the usual fopen warnings,
but the final fatal error becomes an Error exception. Combine
with @ to suppress FS warnings.
Closes GH-5641.
In some places, we need to make sure that no warnings are thrown
due to unknown encoding. The error reporting code tried to avoid
this by determining a "safe charset", but this introduces subtle
discrepancies in which charset is picked (normally
internal_encoding takes precedence). Avoid this by suppressing
the warning in the first place.
While here, use the fallback logic to print error messages with
substitution characters more consistently, to avoid skipping
parts of the error message entirely.
Treatment of locales in PHP is currently inconsistent: The LC_ALL
locale is set to "C", as is standard behavior on program startup.
The LC_CTYPE locale is set to "", which will inherit it from the
environment. However, the inherited LC_CTYPE locale will only be
used in some cases, while in other cases it is necessary to perform
an explicit setlocale() call in PHP first. This is the case for
the locale-sensitive handling in the PCRE extension.
Make things consistent by *never* inheriting any locales from the
environment. LC_ALL, including LC_CTYPE will be "C" on startup.
A locale can be set or inherited through an explicit setlocale()
call, at which point the behavior will be fully consistent and
predictable.
Closes GH-5488.
Even if default_charset is set to "", we should still return
"UTF-8" as the default value here. Setting default_charset to ""
suppresses the header emission, but shouldn't change anything
about our encoding defaults.
This is a backport of fcdc0a6db0
to the PHP-7.3 branch. We need to make sure that OnUpdateString
is also called for a NULL value, otherwise the reset of the encoding
at the end of the request will not work.
I believe I already tried to land this before once, but it didn't
actually end up on the PHP-7.3 branch due to a push conflict that
I only noticed just now.
We need to update the value even if new_value is NULL. In particular,
it should be reset back to NULL after each request if the setting was
not specified on startup. Otherwise we leave dangling pointers.
