-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.
-

-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 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.

-* 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
-*

-Description: APC module for PHP5
- This package provides a module for APC functions.
+Description: Dummy transition package for php-apc
+ The Alternative PHP Cache, also known as APC, is a free, open, and robust
+ framework for caching and optimizing PHP intermediate code. APC is a fast
+ solution for caching PHP code locally, it is not distributed like MemcacheD,
+ but they can be used together for optimal caching.

- * cycles, while in a multi-CPU scenario it's usually better to spin a bit

- * depending on whether we seem to be in a uniprocessor or multiprocessor.
- *
- * Note: you might think MIN_SPINS_PER_DELAY should be just 1, but you'd

- *
- * 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.

- * The PAUSE instruction improves the performance of IA-32

- * polling loop. When executing a spin-wait loop, the
- * processor can suffer a severe performance penalty when
- * exiting the loop because it detects a possible memory order
- * violation and flushes the core processor's pipeline. The
- * PAUSE instruction provides a hint to the processor that the
- * code sequence is a spin-wait loop. The processor uses this
- * hint to avoid the memory order violation and prevent the
- * pipeline flush. In addition, the PAUSE instruction
- * de-pipelines the spin-wait loop to prevent it from
- * consuming execution resources excessively.
