+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:
+
+ svn co http://svn.php.net/repository/pecl/apc/trunk apc
+ cd apc
+ phpize
+ ./configure --with-php-config=/usr/local/php/bin/php-config
+ make
+ export TEST_PHP_ARGS='-n'
+ make test
+ make install
+
+Suggested Configuration (in your php.ini file)
+----------------------------------------------
+ extension=apc.so
+ apc.enabled=1
+ apc.shm_size=128
+ apc.ttl=7200
+ apc.user_ttl=7200
+ apc.enable_cli=1
+
+These are fully described at the bottom of this file.
+
++---------------------+
+| 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 --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.canonicalize Whether to canonicalize paths in stat=0 mode or
+ fall back to stat behaviour if set to 0
+ (Default: 0)
+
+ 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.rfc1867_prefix Key prefix to use for the user cache entry generated by
+ rfc1867 upload progress functionality.
+ (Default: "upload_")
+
+ apc.rfc1867_name Specify the hidden form entry name that activates APC upload
+ progress and specifies the user cache key suffix.
+ (Default: "APC_UPLOAD_PROGRESS")
+
+ apc.rfc1867_freq The frequency that updates should be made to the user cache
+ entry for upload progress. This can take the form of a
+ percentage of the total file size or a size in bytes
+ optionally suffixed with 'k', 'm', or 'g' for kilobytes,
+ megabytes, or gigabytes respectively (case insensitive).
+ A setting of 0 updates as often as possible, which may cause
+ slower uploads.
+ (Default: 0)
+
+ apc.localcache ** REMOVED
+ apc.localcache.size ** REMOVED
+
+ apc.include_once_override
+ Optimize include_once and require_once calls and avoid the
+ expensive system calls used.
+ (Default: 0)

+* Add apc.stat ini flag which defaults to 1. If set to 0, the main script and any fullpath
+ includes will not be stat'ed for any changes. You will have to restart the server if you
+ change anything. This mode increases performance quite a bit, especially if you have a

+
+* Get rid of the lock safety net hack I added in 3.0.9. It seems to cause more problems
+ than it solves. I'll need to revisit locking and signal handling at some point soon.

+
+* Override ZEND_INCLUDE_OR_EVAL opcode (when possible) to speed up use of

+ array with a single loop for copying, jump fixups and auto
+ global pre-fetches. (Gopal)
+
+* Perform fetch_global checks only in php5 and only if
+ auto_globals_jit is enabled. (Gopal)
+
+* Fix bug #8579 - scrub php4 classes' function_table and default
+ properties before inserting into cache. (Gopal)
+
+* Fix bug #8606 - ZEND_FETCH_GLOBAL is not an opcode, but is a
+ op1->type. The opcodes applicable are ZEND_FETCH_R and
+ ZEND_FETCH_W. (Gopal)
+
+* PHP 5.2 Compatibility (Gopal)
+
+* Make the include_once override optional - default off (Sara)
+
+* Fixed crash when apc run in CLI, but enable_cli is off. (Ilia)
+
+* Ensure that the apc_globals->cache_stack is cleared before the
+ shm cache is destroyed. Fixes segfault for corner-case i.e request
+ shutdown (apc_deactivate) is not called before module shutdown
+ calls (php_apc_shutdown_globals) (Gopal)
+
+* TSRM fixes (ensure ts_free_id before apc.so is dlclosed) (Gopal)

+ * 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 {
+ size_t size; /* size of this block */
+ size_t next; /* offset in segment of next free block */
+ size_t canary; /* canary to check for memory overwrites */
+#ifdef __APC_SMA_DEBUG__
+ int id; /* identifier for the memory block */
+#endif
+ };
+
+ 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 hashing 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.
+
+Windows
+
+1. The following configurations (build arguments) have not been implemented yet
+
+ (*) --enable-apc-mmap Memory mapping support
+ (*) --enable-apc-sem Semaphore locking support (FCNTL replacement)
+ (*) --enable-apc-phreadmutex Thread mutexes, while implemented we should probably rename the internals to thread
+
+2. Non-blocking locks is not supported either
+
+3. Update fileinfo to support stat info in a more portable way (see PECL #17903)
