Added PHP API for registering tick functions. Ticks is a per-instruction
callback in Zend that allows us to implement cooperative multitasking
within PHP. Example:
In extension code:
php_add_tick_function(my_tick_func);
void my_tick_func(int count) {
php_printf("[tick %d]", count);
}
In PHP code:
<?php
declare(ticks = 1) {
print "there should be two ticks here.\n";
}
?>
- but as it is Sascha who has reverted a zillion patches I don't feel that
- bad about it :)
- The patch is morally incorrect and it actually also has a crash bug which
- I won't point out because it shouldn't be there.
- SG(path_translated) should be set by the SAPI module correctly and if it
- isn't the SAPI module should be fixed and not add code to PHP. There is
- enough special case code in PHP and I would like to clean it up and not
- add more.
- Last but not least, old_cwd takes 4KB of stack space. We should probably
- malloc() it because in ISAPI we only have 10KB of stack space.
- Post 4.0.2 it's time to move the whole opened_path and virtual stuff
- to emalloc() and friends including some alloca() improvements where
- possible but I don't want to break anything before
to the directory where the executing script is located.
Since this needs to be implemented for all SAPI modules anyway, this
change moves the functionality to php_execute_script() and gets rid
of the per-module code.
- I started with trying to localize the V_FOPEN's so that we can have a
- version which won't really open the file for include_once/require_once to
- work faster and have less chance of a race which would cause a fd leak.
- What I did will, therefore, change but I want to do this step by step
- because the code is extremley messy so first of all I want to make sure
- that the isolating of the V_FOPEN code doesn't break anything.
- How about moving URL stuff out of this file?
- php_fopen_url_wrapper() copy and pasted the second part of
- php_fopen_wrapper() (incorrectly). Please try not to copy&paste code but
- centralize functionality. Need to think of a nice way to nuke one of the
- copies and have both functions use the same one.
