++* Futex (Fast Userspace Mutex) support for APC
++*
++* Futex support provides user space locking with system calls only
++* for the contended cases. Some required reading for this functionality is:
++*
++* 'Fuss, Futexes and Furwocks: Fast Userlevel Locking in Linux'
++* by Hubertus Franke, Rusty Russell, and Matthew Kirkwood
++* http://www.realitydiluted.com/nptl-uclibc/docs/futex.pdf
++*
++* 'Futexes are Tricky' by Ulrich Drepper
++* http://people.redhat.com/drepper/futex.pdf
++*
++*
++* This implementation is optimized and designed for the i386 and x86_64
++* architectures. Other architectures may require additional design
++* to efficiently and safely implement this functionality.
++*
++* Lock values are:
++* 0 = Unlocked
++* 1 = Locked without any waiting processes
++* 2 = Locked with an unknown number of waiting processes
++*

++3.0.11: 2006-08-16
++- Made --enable-apc-mmap the default compile option (for real this time)
++- Add an optional flag to apc_cache_info() and some apc.php tweaks to make it
++ only fetch header information to make it useful when you have tens of
++ thousands of entries. (Brian Shire)
++- 64-bit fixes (George)

++- Override ZEND_INCLUDE_OR_EVAL opcode (when possible) to speed up use of
++ require_once() and include_once() statements. (Sara)

++Installation Instructions for APC
++---------------------------------
++
++This version of APC should work on PHP 4.3.0 - 4.4.x and
++5.1.0 - 5.2.x. Yes, that means PHP 5.0.x is no longer
++supported. Upgrade to PHP 5.1.x or 5.2.x and you will
++notice all sorts of performance increases.
++
++CVS Instructions
++----------------
++Building from CVS can be done like this:
++
++ cvs -d :pserver:cvsread@cvs.php.net:/repository login
++ Password: phpfi
++ cvs -d :pserver:cvsread@cvs.php.net:/repository co pecl/apc
++ cd pecl/apc
++ phpize
++ ./configure --enable-apc-mmap --with-apxs --with-php-config=/usr/local/php/bin/php-config
++ make
++ make install
++
++Suggested Configuration (in your php.ini file)
++----------------------------------------------
++ extension=apc.so
++ apc.enabled=1
++ apc.shm_segments=1
++ apc.shm_size=128
++ apc.ttl=7200
++ apc.user_ttl=7200
++ apc.num_files_hint=1024
++ apc.mmap_file_mask=/tmp/apc.XXXXXX
++ apc.enable_cli=1
++
++These are fully described at the bottom of this file.
++
++PHP 4 Optimization
++------------------
++If you are trying to get every little bit of speed out of PHP4+APC, you need
++to tell APC where to find your httpd.h file and also add -DAPC_PHP4_STAT to
++your CPPFLAGS. (if you don't have httpd.h, install the apache_dev package
++for your OS) and do:
++ export CPPFLAGS="-I/usr/include/apache-1.3 -DAPC_PHP4_STAT" (for bash on Debian)
++ setenv CPPFLAGS "-I/usr/include/apache-1.3 -DAPC_PHP4_STAT" (for tsch on Debian)
++and then re-run your configure script.
++
++This optimization saves a stat syscall on the main script file. In PHP5 this
++optimization is automatic and doesn't need any special build flags.
++
++The second thing you are going to want to do to save another syscall is to
++compile using the --with-apxs configure switch. This should work for both
++Apache1 and Apache2. Point it directly at your apxs2 script for Apache2.
++eg. --with-apxs=/usr/local/bin/apxs2
++
+++---------------------+
++| QUICK INSTALL (DSO) |
+++---------------------+
++
++These instructions assume your PHP installation is located in /usr/local/php and you
++want Apache optimizations (--with-apxs).
++
++$ gunzip -c apc_x.y.tar.gz | tar xf -
++$ cd apc_x.y
++$ /usr/local/php/bin/phpize
++$ ./configure --enable-apc --enable-apc-mmap --with-apxs --with-php-config=/usr/local/php/bin/php-config
++$ make
++$ make install
++
++You will probably need to run the final command (make install) as root.
++
++The above sequence of commands will install a .so file in your PHP
++installation extension directory. The output of make install should display
++that path to the screen.
++
++Next you must edit your php.ini file, which is normally located in
++/usr/local/php/lib/php.ini, and add the following line:
++
++ extension="apc.so"
++
++Replace "/path/to/php/extensions" with whatever path was displayed when you
++ran make install above.
++
++Then restart your web server and consult the output of phpinfo(). If there is
++an informational section for APC, the installation was successful.
++
+++------------------------+
++| QUICK INSTALL (Static) |
+++------------------------+
++
++APC will not successfully compile on all systems as a DSO. If you run into
++problems using the DSO quick install, you can try to compile it statically
++into PHP. (The DSO install is recommended, though.)
++
++These instructions assume the current directory is the root of the PHP source
++tree, and that you have already configured PHP by running its bundled
++configure script.
++
++$ cd ext
++$ gunzip -c apc_x.y.tar.gz | tar xf -
++$ cd ..
++$ ./buildconf
++$ ./config.nice
++$ make
++$ make install
++
++Once this is complete, simply restart your web server. You do not need to
++modify your php.ini file to enable APC.
++
+++-----------------+
++| VERBOSE INSTALL |
+++-----------------+
++
++These instructions assume your PHP installation is located in /usr/local/php.
++
++1. Unpack your distribution file.
++
++ You will have downloaded a file named something like apc_x.y.tar.gz.
++ Unzip this file with a command like
++
++ gunzip apc_x.y.tar.gz
++
++ Next you have to untar it with
++
++ tar xvf apc_x.y.tar
++
++ This will create an apc_x.y directory. cd into this new directory:
++
++ cd apc_x.y
++
++2. Run phpize.
++
++ phpize is a script that should have been installed with PHP, and is
++ normally located in /usr/local/php/bin assuming you installed PHP in
++ /usr/local/php. (If you do not have the phpize script, you must reinstall
++ PHP and be sure not to disable PEAR.)
++
++ Run the phpize command:
++
++ /usr/local/php/bin/phpize
++
++ Its output should resemble this:
++
++ autoheader: `config.h.in' is created
++ You should update your `aclocal.m4' by running aclocal.
++ Configuring for:
++ PHP Api Version: 20020918
++ Zend Module Api No: 20020429
++ Zend Extension Api No: 20021010
++
++ phpize should create a configure script in the current directory. If you
++ get errors instead, you might be missing some required development tools,
++ such as autoconf or libtool. You can try downloading the latest versions
++ of those tools and running phpize again.
++
++3. Run the configure script.
++
++ phpize creates a configure script. The only option you need to specify is
++ the location of your php-config script:
++
++ ./configure --enable-apc
++
++ php-config should be located in the same directory as phpize.
++
++ If you prefer to use mmap instead of the default IPC shared memory support,
++ add --enable-apc-mmap to your configure line.
++
++ If you prefer to use sysv IPC semaphores over the safer fcntl() locks, add
++ --enable-sem to your configure line. If you don't have a problem
++ with your server segaulting, or any other unnatural accumulation of
++ semaphores on your system, the semaphore based locking is slightly faster.
++
++4. Compile and install the files. Simply type: make install
++
++ (You may need to be root in order to install)
++
++ If you encounter errors from libtool or gcc during this step, please
++ contact the project maintainer (dcowgill@php.net).
++
++5. Edit your php.ini
++
++ make install should have printed a line resembling the following:
++
++ Installing shared extensions: /path/to/extension/
++
++ Copy the path /path/to/extension/ and add the following line to your
++ php.ini file (normally located in /usr/local/php/lib/php.ini):
++
++ extension="apc.so"
++
++ If you don't have a php.ini file in that location, you can create it now.
++
++6. Restart the web server and test the installation.
++
++ Restart your web server now (for apache, it's apachectl restart) and
++ create a small test PHP file in your document root. The file should
++ contain just the following line:
++
++ <?php phpinfo() ?>
++
++ Request that file in a web browser. If there is an entry for APC in the
++ list of installed modules, the installation was successful.
++
++ If APC is not listed, consult your web server error log. If it contains an
++ error message saying that it can't load the APC extension, your system
++ might not be able to load shared libraries created with PHP's build
++ system. One alternative would be to compile APC statically into PHP. See
++ the Quick Install (Static) instructions above.
++
++ You should consult your error log anyway to see if APC generated any
++ errors. On BSD-based platforms, it is typical for APC to be unable to
++ allocate the default-sized shared memory segment. See below for hints on
++ raising your system's shared memory limitations.
++
+++-----------------+
++| CONFIGURING APC |
+++-----------------+
++
++Although the default APC settings are fine for many installations, serious
++users should consider tuning the following parameters:
++
++ OPTION DESCRIPTION
++ ------------------ --------------------------------------------------
++ apc.enabled This can be set to 0 to disable APC. This is
++ primarily useful when APC is statically compiled
++ into PHP, since there is no other way to disable
++ it (when compiled as a DSO, the zend_extension
++ line can just be commented-out).
++ (Default: 1)
++
++ apc.shm_segments The number of shared memory segments to allocate
++ for the compiler cache. If APC is running out of
++ shared memory but you have already set
++ apc.shm_size as high as your system allows, you
++ can try raising this value. Setting this to a
++ value other than 1 has no effect in mmap mode
++ since mmap'ed shm segments don't have size limits.
++ (Default: 1)
++
++ apc.shm_size The size of each shared memory segment in MB.
++ By default, some systems (including most BSD
++ variants) have very low limits on the size of a
++ shared memory segment.
++ (Default: 30)
++
++ apc.optimization This option has been deprecated.
++ (Default: 0)
++
++ apc.num_files_hint A "hint" about the number of distinct source files
++ that will be included or requested on your web
++ server. Set to zero or omit if you're not sure;
++ this setting is mainly useful for sites that have
++ many thousands of source files.
++ (Default: 1000)
++
++ apc.user_entries_hint Just like num_files_hint, a "hint" about the number
++ of distinct user cache variables to store.
++ Set to zero or omit if you're not sure;
++ (Default: 4096)
++
++ apc.ttl The number of seconds a cache entry is allowed to
++ idle in a slot in case this cache entry slot is
++ needed by another entry. Leaving this at zero
++ means that your cache could potentially fill up
++ with stale entries while newer entries won't be
++ cached.
++ (Default: 0)
++
++ apc.user_ttl The number of seconds a user cache entry is allowed
++ to idle in a slot in case this cache entry slot is
++ needed by another entry. Leaving this at zero
++ means that your cache could potentially fill up
++ with stale entries while newer entries won't be
++ cached.
++ (Default: 0)
++
++
++ apc.gc_ttl The number of seconds that a cache entry may
++ remain on the garbage-collection list. This value
++ provides a failsafe in the event that a server
++ process dies while executing a cached source file;
++ if that source file is modified, the memory
++ allocated for the old version will not be
++ reclaimed until this TTL reached. Set to zero to
++ disable this feature.
++ (Default: 3600)
++
++ apc.cache_by_default On by default, but can be set to off and used in
++ conjunction with positive apc.filters so that files
++ are only cached if matched by a positive filter.
++ (Default: On)
++
++ apc.filters A comma-separated list of POSIX extended regular
++ expressions. If any pattern matches the source
++ filename, the file will not be cached. Note that
++ the filename used for matching is the one passed
++ to include/require, not the absolute path. If the
++ first character of the expression is a + then the
++ expression will be additive in the sense that any
++ files matched by the expression will be cached, and
++ if the first character is a - then anything matched
++ will not be cached. The - case is the default, so
++ it can be left off.
++ (Default: "")
++
++ apc.mmap_file_mask If compiled with MMAP support by using --enable-mmap
++ this is the mktemp-style file_mask to pass to the
++ mmap module for determing whether your mmap'ed memory
++ region is going to be file-backed or shared memory
++ backed. For straight file-backed mmap, set it to
++ something like /tmp/apc.XXXXXX (exactly 6 X's).
++ To use POSIX-style shm_open/mmap put a ".shm"
++ somewhere in your mask. eg. "/apc.shm.XXXXXX"
++ You can also set it to "/dev/zero" to use your
++ kernel's /dev/zero interface to anonymous mmap'ed
++ memory. Leaving it undefined will force an
++ anonymous mmap.
++ (Default: "")
++
++ apc.slam_defense ** DEPRECATED - Use apc.write_lock instead **
++ On very busy servers whenever you start the server or
++ modify files you can create a race of many processes
++ all trying to cache the same file at the same time.
++ This option sets the percentage of processes that will
++ skip trying to cache an uncached file. Or think of it
++ as the probability of a single process to skip caching.
++ For example, setting this to 75 would mean that there is
++ a 75% chance that the process will not cache an uncached
++ file. So the higher the setting the greater the defense
++ against cache slams. Setting this to 0 disables this
++ feature.
++ (Default: 0)
++
++ apc.file_update_protection
++ When you modify a file on a live web server you really
++ should do so in an atomic manner. That is, write to a
++ temporary file and rename (mv) the file into its permanent
++ position when it is ready. Many text editors, cp, tar and
++ other such programs don't do this. This means that there
++ is a chance that a file is accessed (and cached) while it
++ is still being written to. This file_update_protection
++ setting puts a delay on caching brand new files. The
++ default is 2 seconds which means that if the modification
++ timestamp (mtime) on a file shows that it is less than 2
++ seconds old when it is accessed, it will not be cached.
++ The unfortunate person who accessed this half-written file
++ will still see weirdness, but at least it won't persist.
++ If you are certain you always atomically update your files
++ by using something like rsync which does this correctly, you
++ can turn this protection off by setting it to 0. If you
++ have a system that is flooded with io causing some update
++ procedure to take longer than 2 seconds, you may want to
++ increase this a bit.
++ (Default: 2)
++
++ apc.enable_cli Mostly for testing and debugging. Setting this enables APC
++ for the CLI version of PHP. Normally you wouldn't want to
++ create, populate and tear down the APC cache on every CLI
++ request, but for various test scenarios it is handy to be
++ able to enable APC for the CLI version of APC easily.
++ (Default: 0)
++
++ apc.max_file_size Prevents large files from being cached.
++ (Default: 1M)
++
++ apc.stat Whether to stat the main script file and the fullpath
++ includes. If you turn this off you will need to restart
++ your server in order to update scripts.
++ (Default: 1)
++
++ apc.write_lock On busy servers when you first start up the server, or when
++ many files are modified, you can end up with all your processes
++ trying to compile and cache the same files. With write_lock
++ enabled, only one process at a time will try to compile an
++ uncached script while the other processes will run uncached
++ instead of sitting around waiting on a lock.
++ (Default: 1)
++
++ apc.report_autofilter Logs any scripts that were automatically excluded from being
++ cached due to early/late binding issues.
++ (Default: 0)
++
++ apc.rfc1867 RFC1867 File Upload Progress hook handler is only available
++ if you compiled APC against PHP 5.2.0 or later. When enabled
++ any file uploads which includes a field called
++ APC_UPLOAD_PROGRESS before the file field in an upload form
++ will cause APC to automatically create an upload_<key>
++ user cache entry where <key> is the value of the
++ APC_UPLOAD_PROGRESS form entry.
++
++ Note that the file upload tracking is not threadsafe at this
++ point, so new uploads that happen while a previous one is
++ still going will disable the tracking for the previous.
++ (Default: 0)
++
++ apc.localcache This enables a lock-free local process shadow-cache which
++ reduces lock contention when the cache is being written to.
++ (Default: 0)
++
++ apc.localcache.size The size of the local process shadow-cache, should be set to
++ a sufficently large value, approximately half of num_files_hint.
++ (Default: 512)
++
++ apc.include_once_override
++ Optimize include_once and require_once calls and avoid the
++ expensive system calls used.
++ (Default: 0)

++ *
++ * Once we do decide to block, we use randomly increasing pg_usleep()
++ * delays. The first delay is 1 msec, then the delay randomly increases to
++ * about one second, after which we reset to 1 msec and start again. The
++ * idea here is that in the presence of heavy contention we need to
++ * increase the delay, else the spinlock holder may never get to run and
++ * release the lock. (Consider situation where spinlock holder has been
++ * nice'd down in priority by the scheduler --- it will not get scheduled
++ * until all would-be acquirers are sleeping, so if we always use a 1-msec
++ * sleep, there is a real possibility of starvation.) But we can't just
++ * clamp the delay to an upper bound, else it would take a long time to
++ * make a reasonable number of tries.
++ *
++ * We time out and declare error after NUM_DELAYS delays (thus, exactly
++ * that many tries). With the given settings, this will usually take 2 or
++ * so minutes. It seems better to fix the total number of tries (and thus
++ * the probability of unintended failure) than to fix the total time
++ * spent.
++ *
++ * The pg_usleep() delays are measured in milliseconds because 1 msec is a
++ * common resolution limit at the OS level for newer platforms. On older
++ * platforms the resolution limit is usually 10 msec, in which case the
++ * total delay before timeout will be a bit more.

++ *
++ * s_lock.h
++ * Hardware-dependent implementation of spinlocks.
++ *
++ * NOTE: none of the macros in this file are intended to be called directly.
++ * Call them through the hardware-independent macros in spin.h.
++ *
++ * The following hardware-dependent macros must be provided for each
++ * supported platform:
++ *
++ * void S_INIT_LOCK(slock_t *lock)
++ * Initialize a spinlock (to the unlocked state).
++ *
++ * void S_LOCK(slock_t *lock)
++ * Acquire a spinlock, waiting if necessary.
++ * Time out and abort() if unable to acquire the lock in a
++ * "reasonable" amount of time --- typically ~ 1 minute.
++ *
++ * void S_UNLOCK(slock_t *lock)
++ * Unlock a previously acquired lock.
++ *
++ * bool S_LOCK_FREE(slock_t *lock)
++ * Tests if the lock is free. Returns TRUE if free, FALSE if locked.
++ * This does *not* change the state of the lock.
++ *
++ * void SPIN_DELAY(void)
++ * Delay operation to occur inside spinlock wait loop.
++ *
++ * Note to implementors: there are default implementations for all these
++ * macros at the bottom of the file. Check if your platform can use
++ * these or needs to override them.
++ *
++ * Usually, S_LOCK() is implemented in terms of an even lower-level macro
++ * TAS():
++ *
++ * int TAS(slock_t *lock)
++ * Atomic test-and-set instruction. Attempt to acquire the lock,
++ * but do *not* wait. Returns 0 if successful, nonzero if unable
++ * to acquire the lock.
++ *
++ * TAS() is NOT part of the API, and should never be called directly.
++ *
++ * CAUTION: on some platforms TAS() may sometimes report failure to acquire
++ * a lock even when the lock is not locked. For example, on Alpha TAS()
++ * will "fail" if interrupted. Therefore TAS() should always be invoked
++ * in a retry loop, even if you are certain the lock is free.
++ *
++ * ANOTHER CAUTION: be sure that TAS() and S_UNLOCK() represent sequence
++ * points, ie, loads and stores of other values must not be moved across
++ * a lock or unlock. In most cases it suffices to make the operation be
++ * done through a "volatile" pointer.
++ *
++ * On most supported platforms, TAS() uses a tas() function written
++ * in assembly language to execute a hardware atomic-test-and-set
++ * instruction. Equivalent OS-supplied mutex routines could be used too.
++ *
++ * If no system-specific TAS() is available (ie, HAVE_SPINLOCKS is not
++ * defined), then we fall back on an emulation that uses SysV semaphores
++ * (see spin.c). This emulation will be MUCH MUCH slower than a proper TAS()
++ * implementation, because of the cost of a kernel call per lock or unlock.
++ * An old report is that Postgres spends around 40% of its time in semop(2)
++ * when using the SysV semaphore code.

++APC Quick-Start Braindump
++
++This is a rapidly written braindump of how APC currently works in the
++form of a quick-start guide to start hacking on APC.
++
++1. Install and use APC a bit so you know what it does from the end-user's
++ perspective.
++ user-space functions are all explained here:
++
++2. Grab the current APC code from CVS:
++
++ cvs -d:pserver:cvsread@cvs.php.net:/repository login
++ Password: phpfi
++ cvs -d:pserver:cvsread@cvs.php.net:/repository co pecl/apc
++
++ apc/php_apc.c has most of the code for the user-visible stuff. It is
++ also a regular PHP extension in the sense that there are MINIT, MINFO,
++ MSHUTDOWN, RSHUTDOWN, etc. functions.
++
++3. Build it.
++
++ cd pecl/apc
++ phpize
++ ./configure --enable-apc --enable-mmap
++ make
++ cp modules/apc.so /usr/local/lib/php
++ apachectl restart
++
++4. Debugging Hints
++
++ apachectl stop
++ gdb /usr/bin/httpd
++ break ??
++ run -X
++
++ Grab the .gdbinit from the PHP source tree and have a look at the macros.
++
++5. Look through apc/apc_sma.c
++ It is a pretty standard memory allocator.
++
++ apc_sma_malloc, apc_sma_realloc, apc_sma_strdup and apc_sma_free behave to the
++ caller just like malloc, realloc, strdup and free
++
++ On server startup the MINIT hook in php_apc.c calls apc_module_init() in
++ apc_main.c which in turn calls apc_sma_init(). apc_sma_init calls into
++ apc_mmap.c to mmap the specified sized segment (I tend to just use a single
++ segment). apc_mmap.c should be self-explanatory. It mmaps a temp file and
++ then unlinks that file right after the mmap to provide automatic shared memory
++ cleanup in case the process dies.
++
++ Once the region has been initialized we stick a header_t at the beginning
++ of the region. It contains the total size in header->segsize and the number
++ of bytes available in header->avail.
++
++ After the header comes a bit of a hack. A zero-sized block is inserted just
++ to make things easier later on. And then a huge block that is basically
++ the size of the entire segment minus the two (for the 0-sized block, and this one)
++ block headers.
++
++ The code for this is:
++
++ header = (header_t*) shmaddr;
++ header->segsize = sma_segsize;
++ header->avail = sma_segsize - sizeof(header_t) - sizeof(block_t) - alignword(sizeof(int));
++ memset(&header->lock,0,sizeof(header->lock));
++ sma_lock = &header->lock;
++ block = BLOCKAT(sizeof(header_t));
++ block->size = 0;
++ block->next = sizeof(header_t) + sizeof(block_t);
++ block = BLOCKAT(block->next);
++ block->size = header->avail;
++ block->next = 0;
++
++ So the shared memory looks like this:
++
++ +--------+-------+---------------------------------+
++ | header | block | block |
++ +--------+-------+---------------------------------+
++
++ sma_shmaddrs[0] gives you the address of header
++
++ The blocks are just a simple offset-based linked list (so no pointers):
++
++ typedef struct block_t block_t;
++ struct block_t {
++ int size; /* size of this block */
++ int next; /* offset in segment of next free block */
++ };
++
++ The BLOCKAT macro turns an offset into an actual address for you:
++
++ #define BLOCKAT(offset) ((block_t*)((char *)shmaddr + offset))
++
++ where shmaddr = sma_shaddrs[0]
++
++ And the OFFSET macro goes the other way:
++
++ #define OFFSET(block) ((int)(((char*)block) - (char*)shmaddr))
++
++ Allocating a block with a call to apc_sma_allocate() walks through the
++ linked list of blocks until it finds one that is >= to the requested size.
++ The first call to apc_sma_allocate() will hit the second block. We then
++ chop up that block so it looks like this:
++
++ +--------+-------+-------+-------------------------+
++ | header | block | block | block |
++ +--------+-------+-------+-------------------------+
++
++ Then we unlink that block from the linked list so it won't show up
++ as an available block on the next allocate. So we actually have:
++
++ +--------+-------+ +-------------------------+
++ | header | block |------>| block |
++ +--------+-------+ +-------------------------+
++
++ And header->avail along with block->size of the remaining large
++ block are updated accordingly. The arrow there representing the
++ link which now points to a block with an offset further along in
++ the segment.
++
++ When the block is freed using apc_sma_deallocate() the steps are
++ basically just reversed. The block is put back and then the deallocate
++ code looks at the block before and after to see if the block immediately
++ before and after are free and if so the blocks are combined. So you never
++ have 2 free blocks next to each other, apart from at the front with that
++ 0-sized dummy block. This mostly prevents fragmentation. I have been
++ toying with the idea of always allocating block at 2^n boundaries to make
++ it more likely that they will be re-used to cut down on fragmentation further.
++ That's what the POWER_OF_TWO_BLOCKSIZE you see in apc_sma.c is all about.
++
++ Of course, anytime we fiddle with our shared memory segment we lock using
++ the locking macros, LOCK() and UNLOCK().
++
++ That should mostly take care of the low-level shared memory handling.
++
++6. Next up is apc_main.c and apc_cache.c which implement the meat of the
++ cache logic.
++
++ The apc_main.c file mostly calls functions in apc_sma.c to allocate memory
++ and apc_cache.c for actual cache manipulation.
++
++ After the shared memory segment is created and the caches are initialized,
++ apc_module_init() installs the my_compile_file() function overriding Zend's
++ version. I'll talk about my_compile_file() and the rest of apc_compile.c
++ in the next section. For now I will stick with apc_main.c and apc_cache.c
++ and talk about the actual caches. A cache consists of a block of shared
++ memory returned by apc_sma_allocate() via apc_sma_malloc(). You will
++ notice references to apc_emalloc(). apc_emalloc() is just a thin wrapper
++ around PHP's own emalloc() function which allocates per-process memory from
++ PHP's pool-based memory allocator. Don't confuse apc_emalloc() and
++ apc_sma_malloc() as the first is per-process and the second is shared memory.
++
++ The cache is stored in/described by this struct allocated locally using
++ emalloc():
++
++ struct apc_cache_t {
++ void* shmaddr; /* process (local) address of shared cache */
++ header_t* header; /* cache header (stored in SHM) */
++ slot_t** slots; /* array of cache slots (stored in SHM) */
++ int num_slots; /* number of slots in cache */
++ int gc_ttl; /* maximum time on GC list for a slot */
++ int ttl; /* if slot is needed and entry's access time is older than this ttl, remove it */
++ };
++
++ Whenever you see functions that take a 'cache' argument, this is what they
++ take. And apc_cache_create() returns a pointer to this populated struct.
++
++ At the beginning of the cache we have a header. Remember, we are down a level now
++ from the sma stuff. The sma stuff is the low-level shared-memory allocator which
++ has its own header which is completely separate and invisible to apc_cache.c.
++ As far as apc_cache.c is concerned the block of memory it is working with could
++ have come from a call to malloc().
++
++ The header looks like this:
++
++ typedef struct header_t header_t;
++ struct header_t {
++ int num_hits; /* total successful hits in cache */
++ int num_misses; /* total unsuccessful hits in cache */
++ slot_t* deleted_list; /* linked list of to-be-deleted slots */
++ };
++
++ Since this is at the start of the shared memory segment, these values are accessible
++ across all the yapache processes and hence access to them has to be locked.
++
++ After the header we have an array of slots. The number of slots is user-defined
++ through the apc.num_slots ini hint. Each slot is described by:
++
++ typedef struct slot_t slot_t;
++ struct slot_t {
++ apc_cache_key_t key; /* slot key */
++ apc_cache_entry_t* value; /* slot value */
++ slot_t* next; /* next slot in linked list */
++ int num_hits; /* number of hits to this bucket */
++ time_t creation_time; /* time slot was initialized */
++ time_t deletion_time; /* time slot was removed from cache */
++ time_t access_time; /* time slot was last accessed */
++ };
++
++ The slot_t *next there is a linked list to other slots that happened to hash to the
++ same array position.
++
++ apc_cache_insert() shows what happens on a new cache insert.
++
++ slot = &cache->slots[hash(key) % cache->num_slots];
++
++ cache->slots is our array of slots in the segment. hash() is simply:
++
++ static unsigned int hash(apc_cache_key_t key)
++ {
++ return key.data.file.device + key.data.file.inode;
++ }
++
++ That is, we use the file's device and inode to uniquely identify it. Initially
++ we had used the file's full path, but getting that requires a realpath() call which
++ is amazingly expensive since it has to stat each component of the path to resolve
++ symlinks and get rid of relative path components. By using the device+inode we
++ can uniquely identify a file with a single stat.
++
++ So, on an insert we find the array position in the slots array by hasing the device+inode.
++ If there are currently no other slots there, we just create the slot and stick it into
++ the array:
++
++ *slot = make_slot(key, value, *slot, t)
++
++ If there are other slots already at this position we walk the link list to get to
++ the end. Here is the loop:
++
++ while (*slot) {
++ if (key_equals((*slot)->key.data.file, key.data.file)) {
++ /* If existing slot for the same device+inode is different, remove it and insert the new version */
++ if ((*slot)->key.mtime != key.mtime) {
++ remove_slot(cache, slot);
++ break;
++ }
++ UNLOCK(cache);
++ return 0;
++ } else if(cache->ttl && (*slot)->access_time < (t - cache->ttl)) {
++ remove_slot(cache, slot);
++ continue;
++ }
++ slot = &(*slot)->next;
++ }
++
++ That first key_equals() check sees if we have an exact match meaning the file
++ is already in the cache. Since we try to find the file in the cache before doing
++ an insert, this will generally only happen if another process managed to beat us
++ to inserting it. If we have a newer version of the file at this point we remove
++ it an insert the new version. If our version is not newer we just return without
++ doing anything.
++
++ While walking the linked list we also check to see if the cache has a TTL defined.
++ If while walking the linked list we see a slot that has expired, we remove it
++ since we are right there looking at it. This is the only place we remove stale
++ entries unless the shared memory segment fills up and we force a full expunge via
++ apc_cache_expunge(). apc_cache_expunge() walks the entire slots array and walks
++ down every linked list removing stale slots to free up room. This is obviously
++ slow and thus only happens when we have run out of room.
++
++ apc_cache_find() simply hashes and returns the entry if it is there. If it is there
++ but older than the mtime in the entry we are looking for, we delete the one that is
++ there and return indicating we didn't find it.
++
++ Next we need to understand what an actual cache entry looks like. Have a look at
++ apc_cache.h for the structs. I sort of glossed over the key part earlier saying
++ that we just used the device+inode to find a hash slot. It is actually a bit more
++ complex than that because we have two kinds of caches. We have the standard file
++ cache containing opcode arrays, but we also have a user-controlled cache that the
++ user can insert whatever they want into via apc_store(). For the user cache we
++ obviously don't have a device+inode. The actual identifier is provided by the user
++ as a char *. So the key is actually a union that looks like this:
++
++ typedef union _apc_cache_key_data_t {
++ struct {
++ int device; /* the filesystem device */
++ int inode; /* the filesystem inode */
++ } file;
++ struct {
++ char *identifier;
++ } user;
++ } apc_cache_key_data_t;
++
++ struct apc_cache_key_t {
++ apc_cache_key_data_t data;
++ int mtime; /* the mtime of this cached entry */
++ };
++
++ And we have two sets of functions to do inserts and finds. apc_cache_user_find()
++ and apc_cache_user_insert() operate on the user cache.
++
++ Ok, on to the actual cache entry. Again, because we have two kinds of caches, we
++ also have the corresponding two kinds of cache entries described by this union:
++
++ typedef union _apc_cache_entry_value_t {
++ struct {
++ char *filename; /* absolute path to source file */
++ zend_op_array* op_array; /* op_array allocated in shared memory */
++ apc_function_t* functions; /* array of apc_function_t's */
++ apc_class_t* classes; /* array of apc_class_t's */
++ } file;
++ struct {
++ char *info;
++ zval *val;
++ unsigned int ttl;
++ } user;
++ } apc_cache_entry_value_t;
++
++ And then the actual cache entry:
++
++ struct apc_cache_entry_t {
++ apc_cache_entry_value_t data;
++ unsigned char type;
++ int ref_count;
++ };
++
++ The user entry is pretty simple and not all that important for now. I will
++ concentrate on the file entries since that is what holds the actual compiled
++ opcode arrays along with the functions and classes required by the executor.
++
++ apc_cache_make_file_entry() in apc_cache.c shows how an entry is constructed.
++ The main thing to understand here is that we need more than just the opcode
++ array, we also need the functions and classes created by the compiler when it
++ created the opcode array. As far as the executor is concerned, it doesn't know
++ that it isn't operating in normal mode being called right after the parse/compile
++ phase, so we need to recreate everything so it looks exactly like it would at
++ that point.
++
++7. my_compile_file() and apc_compile.c
++
++ my_compile_file() in apc_main.c controls where we get the opcodes from. If
++ the user-specified filters exclude the file from being cached, then we just
++ call the original compile function and return. Otherwise we fetch the request
++ time from Apache to avoid an extra syscall, create the key so we can look up
++ the file in the cache. If we find it we stick it on a local stack which we
++ use at cleanup time to make sure we return everything back to normal after a
++ request and call cached_compile() which installs the functions and classes
++ associated with the op_array in this entry and then copy the op_array down
++ into our memory space for execution.
++
++ If we didn't find the file in the cache, we need to compile it and insert it.
++ To compile it we simply call the original compile function:
++
++ op_array = old_compile_file(h, type TSRMLS_CC);
++
++ To do the insert we need to copy the functions, classes and the opcode array
++ the compile phase created into shared memory. This all happens in apc_compile.c
++ in the apc_copy_op_array(), apc_copy_new_functions() and apc_copy_new_classes()
++ functions. Then we make the file entry and do the insert. Both of these
++ operations were described in the previous section.
++
++8. The Optimizer
++
++ The optimizer has been deprecated.
++
++If you made it to the end of this, you should have a pretty good idea of where things are in
++the code. I skimmed over a lot of things, so plan on spending some time reading through the code.

++Known Bugs
++
++1. Gallery2 doesn't work with PHP5+APC. There is something wrong
++ with the way methods are restored in some edge case I haven't
++ been able to figure out yet.
++ To reproduce install gallery2 and click down to an individual photo.
++
++2. apc_store() probably needs some checks to skip trying to store
++ internal classes. Something along the lines of:
++
++ if(Z_TYPE_P(val) == IS_OBJECT) {
++ zend_class_entry *ce = Z_OBJCE_P(val);
++ if(ce->type == ZEND_INTERNAL_CLASS) {
++ php_error_docref(NULL TSRMLS_CC, E_WARNING, "Cannot cache internal objects");
++ RETURN_FALSE;
++ }
++ }
++
++ in the apc_store() function in php_apc.c but I am wondering if it needs to do more
++ than that.
++
++Enhancements
++
++1. Some faster platform-specific locking mechanisms wouldd be nice. futex support
++ for the 2.6 Linux kernels, and/or x86-specific spinlock support.
++
++2. The optimizer needs a lot of work.
++
++3. Assert() elimination in the optimizer when some debug flag somewhere isn't set.
