e7f252652f Fix tokenizer test to not depend on specific token numbers 2014-08-26 23:36:53 +02:00

aff56f3c45 add T_POW (**) operator
Fixed recognition of the operator

Added opcode, still doing multiply instead of pow()

opcode now always returns int(42)

The right answer, but always a float

Yanked code from pow() implementation.

Should not handle negative long as exponent ourselves

Added test cases from pow()

Moved precedence higher than '~'

Added GMP operator overloading

Added ZEND_ASSIGN_POW (**=) operator.

Added pow() as a language construct.

Adjusted test cases for changed precedence.

Reduced pow() to shell function around ZEND_API pow_function()

Reduced test case to only contain edge cases
Added overloading test case

Moved unary minus above T_POW

Revert "Added pow() as a language construct."

Bad bad bad idea.

This reverts commit f60b98cf7a8371233d800a6faa286ddba4432d02.

Reverted unary minus behaviour due to previous revert.
Convert arrays to int(0)
Exponent with array as a base becomes int(0)

Rebase against master

Fixed tokenizer test case

  Fix lexing of nested heredoc strings in token_get_all()

4cf90e06c9 Fix lexing of nested heredoc strings in token_get_all()
This fixes bug #60097.

Before two global variables CG(heredoc) and CG(heredoc_len) were used to
track the current heredoc label. In order to support nested heredoc
strings the *previous* heredoc label was assigned as the token value of
T_START_HEREDOC and the language_parser.y assigned that to CG(heredoc).

This created a dependency of the lexer on the parser. Thus the
token_get_all() function, which accesses the lexer directly without
also running the parser, was not able to tokenize nested heredoc strings
(and leaked memory). Same applies for the source-code highlighting
functions.

The new approach is to maintain a heredoc_label_stack in the lexer, which
contains all active heredoc labels.

As it is no longer required, T_START_HEREDOC and T_END_HEREDOC now don't
carry a token value anymore.

In order to make the work with zend_ptr_stack in this context more
convenient I added a new function zend_ptr_stack_top(), which retrieves the
top element of the stack (similar to zend_stack_top()).
