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_ - user cache entry where 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) diff --git a/LICENSE b/LICENSE deleted file mode 100644 index 25662b2..0000000 --- a/LICENSE +++ /dev/null @@ -1,68 +0,0 @@ --------------------------------------------------------------------- - The PHP License, version 3.01 -Copyright (c) 1999 - 2008 The PHP Group.

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.
