file will be #included AFTER <malloc.h>. This is needed only if |
your system defines a struct mallinfo that is incompatible with the |
standard one declared here. Otherwise, you can include this file |
INSTEAD of your system system <malloc.h>. At least on ANSI, all |

malloc(size_t n) |
Returns a pointer to a newly allocated chunk of at least n bytes, or |
null if no space is available, in which case errno is set to ENOMEM |
on ANSI C systems. |
If n is zero, malloc returns a minimum-sized chunk. (The minimum |
size is 16 bytes on most 32bit systems, and 32 bytes on 64bit |
systems.) Note that size_t is an unsigned type, so calls with |
arguments that would be negative if signed are interpreted as |
requests for huge amounts of space, which will often fail. The |
maximum supported value of n differs across systems, but is in all |
cases less than the maximum representable value of a size_t. |
*/ |

/* |
free(void* p) |
Releases the chunk of memory pointed to by p, that had been previously |
allocated using malloc or a related routine such as realloc. |
It has no effect if p is null. If p was not malloced or already |
freed, free(p) will by default cuase the current program to abort. |
*/ |

/* |
calloc(size_t n_elements, size_t element_size); |
Returns a pointer to n_elements * element_size bytes, with all locations |
set to zero. |

void* dlcalloc(size_t, size_t); |
/* |
realloc(void* p, size_t n) |
Returns a pointer to a chunk of size n that contains the same data |
as does chunk p up to the minimum of (n, p's size) bytes, or null |
if no space is available. |
The returned pointer may or may not be the same as p. The algorithm |
prefers extending p in most cases when possible, otherwise it |
employs the equivalent of a malloc-copy-free sequence. |
If p is null, realloc is equivalent to malloc. |
If space is not available, realloc returns null, errno is set (if on |
ANSI) and p is NOT freed. |
if n is for fewer bytes than already held by p, the newly unused |
space is lopped off and freed if possible. realloc with a size |
argument of zero (re)allocates a minimum-sized chunk. |
The old unix realloc convention of allowing the last-free'd chunk |
to be used as an argument to realloc is not supported. |
*/ |
void* dlrealloc(void*, size_t); |
/* |
memalign(size_t alignment, size_t n); |
Returns a pointer to a newly allocated chunk of n bytes, aligned |
in accord with the alignment argument. |
The alignment argument should be a power of two. If the argument is |
not a power of two, the nearest greater power is used. |
8-byte alignment is guaranteed by normal malloc calls, so don't |
bother calling memalign with an argument of 8 or less. |
Overreliance on memalign is a sure way to fragment space. |
*/ |
void* dlmemalign(size_t, size_t); |
/* |
valloc(size_t n); |
Equivalent to memalign(pagesize, n), where pagesize is the page |
size of the system. If the pagesize is unknown, 4096 is used. |
*/ |
void* dlvalloc(size_t); |
/* |
mallopt(int parameter_number, int parameter_value) |
Sets tunable parameters The format is to provide a |
(parameter-number, parameter-value) pair. mallopt then sets the |
corresponding parameter to the argument value if it can (i.e., so |
long as the value is meaningful), and returns 1 if successful else |
0. SVID/XPG/ANSI defines four standard param numbers for mallopt, |
normally defined in malloc.h. None of these are use in this malloc, |
so setting them has no effect. But this malloc also supports other |

independent_calloc(size_t n_elements, size_t element_size, void* chunks[]); |
independent_calloc is similar to calloc, but instead of returning a |
single cleared space, it returns an array of pointers to n_elements |
independent elements that can hold contents of size elem_size, each |
of which starts out cleared, and can be independently freed, |
realloc'ed etc. The elements are guaranteed to be adjacently |
allocated (this is not guaranteed to occur with multiple callocs or |
mallocs), which may also improve cache locality in some |
applications. |
The "chunks" argument is optional (i.e., may be null, which is |
probably the most typical usage). If it is null, the returned array |
is itself dynamically allocated and should also be freed when it is |
no longer needed. Otherwise, the chunks array must be of at least |
n_elements in length. It is filled in with the pointers to the |
chunks. |
In either case, independent_calloc returns this pointer array, or |
null if the allocation failed. If n_elements is zero and "chunks" |
is null, it returns a chunk representing an array with zero elements |
(which should be freed if not wanted). |
Each element must be individually freed when it is no longer |
needed. If you'd like to instead be able to free all at once, you |
should instead use regular calloc and assign pointers into this |
space to represent elements. (In this case though, you cannot |
independently free elements.) |
independent_calloc simplifies and speeds up implementations of many |
kinds of pools. It may also be useful when constructing large data |
structures that initially have a fixed number of fixed-sized nodes, |
but the number is not known at compile time, and some of the nodes |
may later need to be freed. For example: |
struct Node { int item; struct Node* next; }; |
struct Node* build_list() { |
struct Node** pool; |
int n = read_number_of_nodes_needed(); |
if (n <= 0) return 0; |
pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0); |
if (pool == 0) die(); |
// organize into a linked list... |
struct Node* first = pool[0]; |
for (i = 0; i < n-1; ++i) |
pool[i]->next = pool[i+1]; |
free(pool); // Can now free the array (or not, if it is needed later) |
return first; |
} |
*/ |
void** dlindependent_calloc(size_t, size_t, void**); |
/* |
independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]); |
independent_comalloc allocates, all at once, a set of n_elements |
chunks with sizes indicated in the "sizes" array. It returns |
an array of pointers to these elements, each of which can be |
independently freed, realloc'ed etc. The elements are guaranteed to |
be adjacently allocated (this is not guaranteed to occur with |
multiple callocs or mallocs), which may also improve cache locality |
in some applications. |
The "chunks" argument is optional (i.e., may be null). If it is null |
the returned array is itself dynamically allocated and should also |
be freed when it is no longer needed. Otherwise, the chunks array |
must be of at least n_elements in length. It is filled in with the |
pointers to the chunks. |
In either case, independent_comalloc returns this pointer array, or |
null if the allocation failed. If n_elements is zero and chunks is |
null, it returns a chunk representing an array with zero elements |
(which should be freed if not wanted). |
Each element must be individually freed when it is no longer |
needed. If you'd like to instead be able to free all at once, you |
should instead use a single regular malloc, and assign pointers at |
particular offsets in the aggregate space. (In this case though, you |
cannot independently free elements.) |
independent_comallac differs from independent_calloc in that each |
element may have a different size, and also that it does not |
automatically clear elements. |
independent_comalloc can be used to speed up allocation in cases |
where several structs or objects must always be allocated at the |
same time. For example: |
struct Head { ... } |
struct Foot { ... } |
void send_message(char* msg) { |
int msglen = strlen(msg); |
size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) }; |
void* chunks[3]; |
if (independent_comalloc(3, sizes, chunks) == 0) |
die(); |
struct Head* head = (struct Head*)(chunks[0]); |
char* body = (char*)(chunks[1]); |
struct Foot* foot = (struct Foot*)(chunks[2]); |
// ... |
} |
In general though, independent_comalloc is worth using only for |
larger values of n_elements. For small values, you probably won't |
detect enough difference from series of malloc calls to bother. |
Overuse of independent_comalloc can increase overall memory usage, |
since it cannot reuse existing noncontiguous small chunks that |
might be available for some of the elements. |

malloc_trim(size_t pad); |
If possible, gives memory back to the system (via negative arguments |

large blocks of memory to potentially reduce the system-level memory |
requirements of a program. However, it cannot guarantee to reduce |
memory. Under some allocation patterns, some large free blocks of |
memory will be locked between two used chunks, so they cannot be |
given back to the system. |
The `pad' argument to malloc_trim represents the amount of free |
trailing space to leave untrimmed. If this argument is zero, only |
the minimum amount of memory to maintain internal data structures |
will be left. Non-zero arguments can be supplied to maintain enough |
trailing space to service future expected allocations without having |
to re-obtain memory from the system. |
Malloc_trim returns 1 if it actually released any memory, else 0. |

overwriting other allocated objects. This is not a particularly great |
programming practice. malloc_usable_size can be more useful in |
debugging and assertions, for example: |
p = malloc(n); |
assert(malloc_usable_size(p) >= 256); |

number of bytes allocated via malloc (or realloc, etc) but not yet |
freed. Note that this is the number of bytes allocated, not the |
number requested. It will be larger than the number requested |
because of alignment and bookkeeping overhead. Because it includes |
alignment wastage as being in use, this figure may be greater than |
zero even when no user-level chunks are allocated. |
The reported current and maximum system memory can be inaccurate if |
a program makes other calls to system memory allocation functions |

/** |
* Asynchronous library |
* |
* The aim of this library is facilitating writing programs utilizing |
* the asynchronous nature of HelenOS IPC, yet using a normal way |
* of programming. |
* |
* You should be able to write very simple multithreaded programs, |
* the async framework will automatically take care of most synchronization |
* problems. |
* |
* Default semantics: |
* - send() - send asynchronously. If the kernel refuses to send more |
* messages, [ try to get responses from kernel, if nothing |
* found, might try synchronous ] |
* |
* Example of use: |
* |
* 1) Multithreaded client application |
* create_thread(thread1); |
* create_thread(thread2); |
* ... |
* |
* thread1() { |
* conn = ipc_connect_me_to(); |
* c1 = send(conn); |
* c2 = send(conn); |
* wait_for(c1); |
* wait_for(c2); |
* } |
* |
* |
* 2) Multithreaded server application |
* main() { |
* async_manager(); |
* } |
* |
* |
* client_connection(icallid, *icall) { |
* if (want_refuse) { |
* ipc_answer_fast(icallid, ELIMIT, 0, 0); |
* return; |
* } |
* ipc_answer_fast(icallid, 0, 0, 0); |
* |
* callid = async_get_call(&call); |
* handle(callid, call); |
* ipc_answer_fast(callid, 1, 2, 3); |

* callid = async_get_call(&call); |

/** Print formatted string. |
* |
* Print string formatted according to the fmt parameter |
* and variadic arguments. Each formatting directive |
* must have the following form: |
* |
* \% [ FLAGS ] [ WIDTH ] [ .PRECISION ] [ TYPE ] CONVERSION |
* |
* FLAGS:@n |
* - "#" Force to print prefix. |
* For conversion \%o the prefix is 0, for %x and \%X prefixes are 0x and 0X |
* and for conversion \%b the prefix is 0b. |
* |
* - "-" Align to left. |
* |
* - "+" Print positive sign just as negative. |
* |
* - " " If the printed number is positive and "+" flag is not set, print space in |
* place of sign. |
* |
* - "0" Print 0 as padding instead of spaces. Zeroes are placed between sign and the |
* rest of the number. This flag is ignored if "-" flag is specified. |
* |
* WIDTH:@n |
* - Specify minimal width of printed argument. If it is bigger, width is ignored. |
* If width is specified with a "*" character instead of number, width is taken from |
* parameter list. And integer parameter is expected before parameter for processed |
* conversion specification. If this value is negative its absolute value is taken |
* and the "-" flag is set. |
* |
* PRECISION:@n |
* - Value precision. For numbers it specifies minimum valid numbers. |
* Smaller numbers are printed with leading zeroes. Bigger numbers are not affected. |
* Strings with more than precision characters are cut off. |
* Just as with width, an "*" can be used used instead of a number. |
* An integer value is then expected in parameters. When both width and precision |
* are specified using "*", the first parameter is used for width and the second one |
* for precision. |
* |
* TYPE:@n |
* - "hh" Signed or unsigned char.@n |
* - "h" Signed or usigned short.@n |
* - "" Signed or usigned int (default value).@n |
* - "l" Signed or usigned long int.@n |
* - "ll" Signed or usigned long long int.@n |
* - "z" Type size_t.@n |
* |
* |
* CONVERSION:@n |
* - % Print percentile character itself. |
* |
* - c Print single character. |
* |
* - s Print zero terminated string. If a NULL value is passed as value, "(NULL)" is printed instead. |
* |
* - P, p Print value of a pointer. Void * value is expected and it is printed in hexadecimal notation with prefix |
* (as with '\%#X' or '\%#x' for 32bit or '\%#X' or '\%#x' for 64bit long pointers). |
* |
* - b Print value as unsigned binary number. Prefix is not printed by default. (Nonstandard extension.) |
* |
* - o Print value as unsigned octal number. Prefix is not printed by default. |
* |
* - d,i Print signed decimal number. There is no difference between d and i conversion. |
* |
* - u Print unsigned decimal number. |
* |
* - X, x Print hexadecimal number with upper- or lower-case. Prefix is not printed by default. |
* |
* All other characters from fmt except the formatting directives |
* are printed in verbatim. |
* |
* @param fmt Formatting NULL terminated string. |
* @return Number of printed characters or negative value on failure. |

* Note about race conditions. |
* Because of non-atomic nature of operations performed sequentially on the futex |
* counter and the futex wait queue, there is a race condition: |
* |
* (wq->missed_wakeups == 1) && (futex->count = 1) |
* |
* Scenario 1 (wait queue timeout vs. futex_up()): |
* 1. assume wq->missed_wakeups == 0 && futex->count == -1 |
* (ie. thread A sleeping, thread B in the critical section) |
* 2. A receives timeout and gets removed from the wait queue |
* 3. B wants to leave the critical section and calls futex_up() |
* 4. B thus changes futex->count from -1 to 0 |
* 5. B has to call SYS_FUTEX_WAKEUP syscall to wake up the sleeping thread |
* 6. B finds the wait queue empty and changes wq->missed_wakeups from 0 to 1 |
* 7. A fixes futex->count (i.e. the number of waiting threads) by changing it from 0 to 1 |
* |
* Scenario 2 (conditional down operation vs. futex_up) |
* 1. assume wq->missed_wakeups == 0 && futex->count == 0 |
* (i.e. thread A is in the critical section) |
* 2. thread B performs futex_trydown() operation and changes futex->count from 0 to -1 |
* B is now obliged to call SYS_FUTEX_SLEEP syscall |
* 3. A wants to leave the critical section and does futex_up() |
* 4. A thus changes futex->count from -1 to 0 and must call SYS_FUTEX_WAKEUP syscall |
* 5. B finds the wait queue empty and immediatelly aborts the conditional sleep |
* 6. No thread is queueing in the wait queue so wq->missed_wakeups changes from 0 to 1 |
* 6. B fixes futex->count (i.e. the number of waiting threads) by changing it from 0 to 1 |
* |
* Both scenarios allow two threads to be in the critical section simultaneously. |
* One without kernel intervention and the other through wq->missed_wakeups being 1. |
* |
* To mitigate this problem, futex_down_timeout() detects that the syscall didn't sleep |
* in the wait queue, fixes the futex counter and RETRIES the whole operation again. |

This is a version (aka dlmalloc) of malloc/free/realloc written by |
Doug Lea and released to the public domain, as explained at |
http://creativecommons.org/licenses/publicdomain. Send questions, |
comments, complaints, performance data, etc to dl@cs.oswego.edu |
* Version 2.8.3 Thu Sep 22 11:16:15 2005 Doug Lea (dl at gee) |
Note: There may be an updated version of this malloc obtainable at |
ftp://gee.cs.oswego.edu/pub/misc/malloc.c |
Check before installing! |
* Quickstart |
This library is all in one file to simplify the most common usage: |
ftp it, compile it (-O3), and link it into another program. All of |
the compile-time options default to reasonable values for use on |
most platforms. You might later want to step through various |
compile-time and dynamic tuning options. |
For convenience, an include file for code using this malloc is at: |
ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h |
You don't really need this .h file unless you call functions not |
defined in your system include files. The .h file contains only the |
excerpts from this file needed for using this malloc on ANSI C/C++ |
systems, so long as you haven't changed compile-time options about |
naming and tuning parameters. If you do, then you can create your |
own malloc.h that does include all settings by cutting at the point |
indicated below. Note that you may already by default be using a C |
library containing a malloc that is based on some version of this |
malloc (for example in linux). You might still want to use the one |
in this file to customize settings or to avoid overheads associated |
with library versions. |
* Vital statistics: |
Supported pointer/size_t representation: 4 or 8 bytes |
size_t MUST be an unsigned type of the same width as |
pointers. (If you are using an ancient system that declares |
size_t as a signed type, or need it to be a different width |
than pointers, you can use a previous release of this malloc |
(e.g. 2.7.2) supporting these.) |
Alignment: 8 bytes (default) |
This suffices for nearly all current machines and C compilers. |
However, you can define MALLOC_ALIGNMENT to be wider than this |
if necessary (up to 128bytes), at the expense of using more space. |
Minimum overhead per allocated chunk: 4 or 8 bytes (if 4byte sizes) |
8 or 16 bytes (if 8byte sizes) |
Each malloced chunk has a hidden word of overhead holding size |
and status information, and additional cross-check word |
if FOOTERS is defined. |
Minimum allocated size: 4-byte ptrs: 16 bytes (including overhead) |
8-byte ptrs: 32 bytes (including overhead) |
Even a request for zero bytes (i.e., malloc(0)) returns a |
pointer to something of the minimum allocatable size. |
The maximum overhead wastage (i.e., number of extra bytes |
allocated than were requested in malloc) is less than or equal |
to the minimum size, except for requests >= mmap_threshold that |
are serviced via mmap(), where the worst case wastage is about |
32 bytes plus the remainder from a system page (the minimal |
mmap unit); typically 4096 or 8192 bytes. |
Security: static-safe; optionally more or less |
The "security" of malloc refers to the ability of malicious |
code to accentuate the effects of errors (for example, freeing |
space that is not currently malloc'ed or overwriting past the |
ends of chunks) in code that calls malloc. This malloc |
guarantees not to modify any memory locations below the base of |
heap, i.e., static variables, even in the presence of usage |
errors. The routines additionally detect most improper frees |
and reallocs. All this holds as long as the static bookkeeping |
for malloc itself is not corrupted by some other means. This |
is only one aspect of security -- these checks do not, and |
cannot, detect all possible programming errors. |
If FOOTERS is defined nonzero, then each allocated chunk |
carries an additional check word to verify that it was malloced |
from its space. These check words are the same within each |
execution of a program using malloc, but differ across |
executions, so externally crafted fake chunks cannot be |
freed. This improves security by rejecting frees/reallocs that |
could corrupt heap memory, in addition to the checks preventing |
writes to statics that are always on. This may further improve |
security at the expense of time and space overhead. (Note that |
FOOTERS may also be worth using with MSPACES.) |
By default detected errors cause the program to abort (calling |
"abort()"). You can override this to instead proceed past |
errors by defining PROCEED_ON_ERROR. In this case, a bad free |
has no effect, and a malloc that encounters a bad address |
caused by user overwrites will ignore the bad address by |
dropping pointers and indices to all known memory. This may |
be appropriate for programs that should continue if at all |
possible in the face of programming errors, although they may |
run out of memory because dropped memory is never reclaimed. |
If you don't like either of these options, you can define |
CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything |
else. And if if you are sure that your program using malloc has |
no errors or vulnerabilities, you can define INSECURE to 1, |
which might (or might not) provide a small performance improvement. |
Thread-safety: NOT thread-safe unless USE_LOCKS defined |
When USE_LOCKS is defined, each public call to malloc, free, |
etc is surrounded with either a pthread mutex or a win32 |
spinlock (depending on WIN32). This is not especially fast, and |
can be a major bottleneck. It is designed only to provide |
minimal protection in concurrent environments, and to provide a |
basis for extensions. If you are using malloc in a concurrent |
program, consider instead using ptmalloc, which is derived from |
a version of this malloc. (See http://www.malloc.de). |
System requirements: Any combination of MORECORE and/or MMAP/MUNMAP |
This malloc can use unix sbrk or any emulation (invoked using |
the CALL_MORECORE macro) and/or mmap/munmap or any emulation |
(invoked using CALL_MMAP/CALL_MUNMAP) to get and release system |
memory. On most unix systems, it tends to work best if both |
MORECORE and MMAP are enabled. On Win32, it uses emulations |
based on VirtualAlloc. It also uses common C library functions |
like memset. |
Compliance: I believe it is compliant with the Single Unix Specification |
(See http://www.unix.org). Also SVID/XPG, ANSI C, and probably |
others as well. |
* Overview of algorithms |
This is not the fastest, most space-conserving, most portable, or |
most tunable malloc ever written. However it is among the fastest |
while also being among the most space-conserving, portable and |
tunable. Consistent balance across these factors results in a good |
general-purpose allocator for malloc-intensive programs. |
In most ways, this malloc is a best-fit allocator. Generally, it |
chooses the best-fitting existing chunk for a request, with ties |
broken in approximately least-recently-used order. (This strategy |
normally maintains low fragmentation.) However, for requests less |
than 256bytes, it deviates from best-fit when there is not an |
exactly fitting available chunk by preferring to use space adjacent |
to that used for the previous small request, as well as by breaking |
ties in approximately most-recently-used order. (These enhance |
locality of series of small allocations.) And for very large requests |
(>= 256Kb by default), it relies on system memory mapping |
facilities, if supported. (This helps avoid carrying around and |
possibly fragmenting memory used only for large chunks.) |
All operations (except malloc_stats and mallinfo) have execution |
times that are bounded by a constant factor of the number of bits in |
a size_t, not counting any clearing in calloc or copying in realloc, |
or actions surrounding MORECORE and MMAP that have times |
proportional to the number of non-contiguous regions returned by |
system allocation routines, which is often just 1. |
The implementation is not very modular and seriously overuses |
macros. Perhaps someday all C compilers will do as good a job |
inlining modular code as can now be done by brute-force expansion, |
but now, enough of them seem not to. |
Some compilers issue a lot of warnings about code that is |
dead/unreachable only on some platforms, and also about intentional |
uses of negation on unsigned types. All known cases of each can be |
ignored. |
For a longer but out of date high-level description, see |
http://gee.cs.oswego.edu/dl/html/malloc.html |
* MSPACES |
If MSPACES is defined, then in addition to malloc, free, etc., |
this file also defines mspace_malloc, mspace_free, etc. These |
are versions of malloc routines that take an "mspace" argument |
obtained using create_mspace, to control all internal bookkeeping. |
If ONLY_MSPACES is defined, only these versions are compiled. |
So if you would like to use this allocator for only some allocations, |
and your system malloc for others, you can compile with |
ONLY_MSPACES and then do something like... |
static mspace mymspace = create_mspace(0,0); // for example |
#define mymalloc(bytes) mspace_malloc(mymspace, bytes) |
(Note: If you only need one instance of an mspace, you can instead |
use "USE_DL_PREFIX" to relabel the global malloc.) |
You can similarly create thread-local allocators by storing |
mspaces as thread-locals. For example: |
static __thread mspace tlms = 0; |
void* tlmalloc(size_t bytes) { |
if (tlms == 0) tlms = create_mspace(0, 0); |
return mspace_malloc(tlms, bytes); |
} |
void tlfree(void* mem) { mspace_free(tlms, mem); } |
Unless FOOTERS is defined, each mspace is completely independent. |
You cannot allocate from one and free to another (although |
conformance is only weakly checked, so usage errors are not always |
caught). If FOOTERS is defined, then each chunk carries around a tag |
indicating its originating mspace, and frees are directed to their |
originating spaces. |
------------------------- Compile-time options --------------------------- |
Be careful in setting #define values for numerical constants of type |
size_t. On some systems, literal values are not automatically extended |
to size_t precision unless they are explicitly casted. |
WIN32 default: defined if _WIN32 defined |
Defining WIN32 sets up defaults for MS environment and compilers. |
Otherwise defaults are for unix. |
MALLOC_ALIGNMENT default: (size_t)8 |
Controls the minimum alignment for malloc'ed chunks. It must be a |
power of two and at least 8, even on machines for which smaller |
alignments would suffice. It may be defined as larger than this |
though. Note however that code and data structures are optimized for |
the case of 8-byte alignment. |
MSPACES default: 0 (false) |
If true, compile in support for independent allocation spaces. |
This is only supported if HAVE_MMAP is true. |
ONLY_MSPACES default: 0 (false) |
If true, only compile in mspace versions, not regular versions. |
USE_LOCKS default: 0 (false) |
Causes each call to each public routine to be surrounded with |
pthread or WIN32 mutex lock/unlock. (If set true, this can be |
overridden on a per-mspace basis for mspace versions.) |
FOOTERS default: 0 |
If true, provide extra checking and dispatching by placing |
information in the footers of allocated chunks. This adds |
space and time overhead. |
INSECURE default: 0 |
If true, omit checks for usage errors and heap space overwrites. |
USE_DL_PREFIX default: NOT defined |
Causes compiler to prefix all public routines with the string 'dl'. |
This can be useful when you only want to use this malloc in one part |
of a program, using your regular system malloc elsewhere. |
ABORT default: defined as abort() |
Defines how to abort on failed checks. On most systems, a failed |
check cannot die with an "assert" or even print an informative |
message, because the underlying print routines in turn call malloc, |
which will fail again. Generally, the best policy is to simply call |
abort(). It's not very useful to do more than this because many |
errors due to overwriting will show up as address faults (null, odd |
addresses etc) rather than malloc-triggered checks, so will also |
abort. Also, most compilers know that abort() does not return, so |
can better optimize code conditionally calling it. |
PROCEED_ON_ERROR default: defined as 0 (false) |
Controls whether detected bad addresses cause them to bypassed |
rather than aborting. If set, detected bad arguments to free and |
realloc are ignored. And all bookkeeping information is zeroed out |
upon a detected overwrite of freed heap space, thus losing the |
ability to ever return it from malloc again, but enabling the |
application to proceed. If PROCEED_ON_ERROR is defined, the |
static variable malloc_corruption_error_count is compiled in |
and can be examined to see if errors have occurred. This option |
generates slower code than the default abort policy. |
DEBUG default: NOT defined |
The DEBUG setting is mainly intended for people trying to modify |
this code or diagnose problems when porting to new platforms. |
However, it may also be able to better isolate user errors than just |
using runtime checks. The assertions in the check routines spell |
out in more detail the assumptions and invariants underlying the |
algorithms. The checking is fairly extensive, and will slow down |
execution noticeably. Calling malloc_stats or mallinfo with DEBUG |
set will attempt to check every non-mmapped allocated and free chunk |
in the course of computing the summaries. |
ABORT_ON_ASSERT_FAILURE default: defined as 1 (true) |
Debugging assertion failures can be nearly impossible if your |
version of the assert macro causes malloc to be called, which will |
lead to a cascade of further failures, blowing the runtime stack. |
ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(), |
which will usually make debugging easier. |
MALLOC_FAILURE_ACTION default: sets errno to ENOMEM, or no-op on win32 |
The action to take before "return 0" when malloc fails to be able to |
return memory because there is none available. |
HAVE_MORECORE default: 1 (true) unless win32 or ONLY_MSPACES |
True if this system supports sbrk or an emulation of it. |
MORECORE default: sbrk |
The name of the sbrk-style system routine to call to obtain more |
memory. See below for guidance on writing custom MORECORE |
functions. The type of the argument to sbrk/MORECORE varies across |
systems. It cannot be size_t, because it supports negative |
arguments, so it is normally the signed type of the same width as |
size_t (sometimes declared as "intptr_t"). It doesn't much matter |
though. Internally, we only call it with arguments less than half |
the max value of a size_t, which should work across all reasonable |
possibilities, although sometimes generating compiler warnings. See |
near the end of this file for guidelines for creating a custom |
version of MORECORE. |
MORECORE_CONTIGUOUS default: 1 (true) |
If true, take advantage of fact that consecutive calls to MORECORE |
with positive arguments always return contiguous increasing |
addresses. This is true of unix sbrk. It does not hurt too much to |
set it true anyway, since malloc copes with non-contiguities. |
Setting it false when definitely non-contiguous saves time |
and possibly wasted space it would take to discover this though. |
MORECORE_CANNOT_TRIM default: NOT defined |
True if MORECORE cannot release space back to the system when given |
negative arguments. This is generally necessary only if you are |
using a hand-crafted MORECORE function that cannot handle negative |
arguments. |
HAVE_MMAP default: 1 (true) |
True if this system supports mmap or an emulation of it. If so, and |
HAVE_MORECORE is not true, MMAP is used for all system |
allocation. If set and HAVE_MORECORE is true as well, MMAP is |
primarily used to directly allocate very large blocks. It is also |
used as a backup strategy in cases where MORECORE fails to provide |
space from system. Note: A single call to MUNMAP is assumed to be |
able to unmap memory that may have be allocated using multiple calls |
to MMAP, so long as they are adjacent. |
HAVE_MREMAP default: 1 on linux, else 0 |
If true realloc() uses mremap() to re-allocate large blocks and |
extend or shrink allocation spaces. |
MMAP_CLEARS default: 1 on unix |
True if mmap clears memory so calloc doesn't need to. This is true |
for standard unix mmap using /dev/zero. |
USE_BUILTIN_FFS default: 0 (i.e., not used) |
Causes malloc to use the builtin ffs() function to compute indices. |
Some compilers may recognize and intrinsify ffs to be faster than the |
supplied C version. Also, the case of x86 using gcc is special-cased |
to an asm instruction, so is already as fast as it can be, and so |
this setting has no effect. (On most x86s, the asm version is only |
slightly faster than the C version.) |
malloc_getpagesize default: derive from system includes, or 4096. |
The system page size. To the extent possible, this malloc manages |
memory from the system in page-size units. This may be (and |
usually is) a function rather than a constant. This is ignored |
if WIN32, where page size is determined using getSystemInfo during |
initialization. |
USE_DEV_RANDOM default: 0 (i.e., not used) |
Causes malloc to use /dev/random to initialize secure magic seed for |
stamping footers. Otherwise, the current time is used. |
NO_MALLINFO default: 0 |
If defined, don't compile "mallinfo". This can be a simple way |
of dealing with mismatches between system declarations and |
those in this file. |
MALLINFO_FIELD_TYPE default: size_t |
The type of the fields in the mallinfo struct. This was originally |
defined as "int" in SVID etc, but is more usefully defined as |
size_t. The value is used only if HAVE_USR_INCLUDE_MALLOC_H is not set |
REALLOC_ZERO_BYTES_FREES default: not defined |
This should be set if a call to realloc with zero bytes should |
be the same as a call to free. Some people think it should. Otherwise, |
since this malloc returns a unique pointer for malloc(0), so does |
realloc(p, 0). |
LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H |
LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H, LACKS_ERRNO_H |
LACKS_STDLIB_H default: NOT defined unless on WIN32 |
Define these if your system does not have these header files. |
You might need to manually insert some of the declarations they provide. |
DEFAULT_GRANULARITY default: page size if MORECORE_CONTIGUOUS, |
system_info.dwAllocationGranularity in WIN32, |
otherwise 64K. |
Also settable using mallopt(M_GRANULARITY, x) |
The unit for allocating and deallocating memory from the system. On |
most systems with contiguous MORECORE, there is no reason to |
make this more than a page. However, systems with MMAP tend to |
either require or encourage larger granularities. You can increase |
this value to prevent system allocation functions to be called so |
often, especially if they are slow. The value must be at least one |
page and must be a power of two. Setting to 0 causes initialization |
to either page size or win32 region size. (Note: In previous |
versions of malloc, the equivalent of this option was called |
"TOP_PAD") |
DEFAULT_TRIM_THRESHOLD default: 2MB |
Also settable using mallopt(M_TRIM_THRESHOLD, x) |
The maximum amount of unused top-most memory to keep before |
releasing via malloc_trim in free(). Automatic trimming is mainly |
useful in long-lived programs using contiguous MORECORE. Because |
trimming via sbrk can be slow on some systems, and can sometimes be |
wasteful (in cases where programs immediately afterward allocate |
more large chunks) the value should be high enough so that your |
overall system performance would improve by releasing this much |
memory. As a rough guide, you might set to a value close to the |
average size of a process (program) running on your system. |
Releasing this much memory would allow such a process to run in |
memory. Generally, it is worth tuning trim thresholds when a |
program undergoes phases where several large chunks are allocated |
and released in ways that can reuse each other's storage, perhaps |
mixed with phases where there are no such chunks at all. The trim |
value must be greater than page size to have any useful effect. To |
disable trimming completely, you can set to MAX_SIZE_T. Note that the trick |
some people use of mallocing a huge space and then freeing it at |
program startup, in an attempt to reserve system memory, doesn't |
have the intended effect under automatic trimming, since that memory |
will immediately be returned to the system. |
DEFAULT_MMAP_THRESHOLD default: 256K |
Also settable using mallopt(M_MMAP_THRESHOLD, x) |
The request size threshold for using MMAP to directly service a |
request. Requests of at least this size that cannot be allocated |
using already-existing space will be serviced via mmap. (If enough |
normal freed space already exists it is used instead.) Using mmap |
segregates relatively large chunks of memory so that they can be |
individually obtained and released from the host system. A request |
serviced through mmap is never reused by any other request (at least |
not directly; the system may just so happen to remap successive |
requests to the same locations). Segregating space in this way has |
the benefits that: Mmapped space can always be individually released |
back to the system, which helps keep the system level memory demands |
of a long-lived program low. Also, mapped memory doesn't become |
`locked' between other chunks, as can happen with normally allocated |
chunks, which means that even trimming via malloc_trim would not |
release them. However, it has the disadvantage that the space |
cannot be reclaimed, consolidated, and then used to service later |
requests, as happens with normal chunks. The advantages of mmap |
nearly always outweigh disadvantages for "large" chunks, but the |
value of "large" may vary across systems. The default is an |
empirically derived value that works well in most systems. You can |
disable mmap by setting to MAX_SIZE_T. |

/* ----------------------- Chunk representations ------------------------ */ |
/* |
(The following includes lightly edited explanations by Colin Plumb.) |
The malloc_chunk declaration below is misleading (but accurate and |
necessary). It declares a "view" into memory allowing access to |
necessary fields at known offsets from a given base. |
Chunks of memory are maintained using a `boundary tag' method as |
originally described by Knuth. (See the paper by Paul Wilson |
ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such |
techniques.) Sizes of free chunks are stored both in the front of |
each chunk and at the end. This makes consolidating fragmented |
chunks into bigger chunks fast. The head fields also hold bits |
representing whether chunks are free or in use. |
Here are some pictures to make it clearer. They are "exploded" to |
show that the state of a chunk can be thought of as extending from |
the high 31 bits of the head field of its header through the |
prev_foot and PINUSE_BIT bit of the following chunk header. |
A chunk that's in use looks like: |
chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Size of previous chunk (if P = 1) | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P| |
| Size of this chunk 1| +-+ |
mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| | |
+- -+ |
| | |
+- -+ |
| : |
+- size - sizeof(size_t) available payload bytes -+ |
: | |
chunk-> +- -+ |
| | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1| |
| Size of next chunk (may or may not be in use) | +-+ |
mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
And if it's free, it looks like this: |
chunk-> +- -+ |
| User payload (must be in use, or we would have merged!) | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P| |
| Size of this chunk 0| +-+ |
mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Next pointer | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Prev pointer | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| : |
+- size - sizeof(struct chunk) unused bytes -+ |
: | |
chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Size of this chunk | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |0| |
| Size of next chunk (must be in use, or we would have merged)| +-+ |
mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| : |
+- User payload -+ |
: | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
|0| |
+-+ |
Note that since we always merge adjacent free chunks, the chunks |
adjacent to a free chunk must be in use. |
Given a pointer to a chunk (which can be derived trivially from the |
payload pointer) we can, in O(1) time, find out whether the adjacent |
chunks are free, and if so, unlink them from the lists that they |
are on and merge them with the current chunk. |
Chunks always begin on even word boundaries, so the mem portion |
(which is returned to the user) is also on an even word boundary, and |
thus at least double-word aligned. |
The P (PINUSE_BIT) bit, stored in the unused low-order bit of the |
chunk size (which is always a multiple of two words), is an in-use |
bit for the *previous* chunk. If that bit is *clear*, then the |
word before the current chunk size contains the previous chunk |
size, and can be used to find the front of the previous chunk. |
The very first chunk allocated always has this bit set, preventing |
access to non-existent (or non-owned) memory. If pinuse is set for |
any given chunk, then you CANNOT determine the size of the |
previous chunk, and might even get a memory addressing fault when |
trying to do so. |
The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of |
the chunk size redundantly records whether the current chunk is |
inuse. This redundancy enables usage checks within free and realloc, |
and reduces indirection when freeing and consolidating chunks. |
Each freshly allocated chunk must have both cinuse and pinuse set. |
That is, each allocated chunk borders either a previously allocated |
and still in-use chunk, or the base of its memory arena. This is |
ensured by making all allocations from the the `lowest' part of any |
found chunk. Further, no free chunk physically borders another one, |
so each free chunk is known to be preceded and followed by either |
inuse chunks or the ends of memory. |
Note that the `foot' of the current chunk is actually represented |
as the prev_foot of the NEXT chunk. This makes it easier to |
deal with alignments etc but can be very confusing when trying |
to extend or adapt this code. |
The exceptions to all this are |
1. The special chunk `top' is the top-most available chunk (i.e., |
the one bordering the end of available memory). It is treated |
specially. Top is never included in any bin, is used only if |
no other chunk is available, and is released back to the |
system if it is very large (see M_TRIM_THRESHOLD). In effect, |
the top chunk is treated as larger (and thus less well |
fitting) than any other available chunk. The top chunk |
doesn't update its trailing size field since there is no next |
contiguous chunk that would have to index off it. However, |
space is still allocated for it (TOP_FOOT_SIZE) to enable |
separation or merging when space is extended. |
3. Chunks allocated via mmap, which have the lowest-order bit |
(IS_MMAPPED_BIT) set in their prev_foot fields, and do not set |
PINUSE_BIT in their head fields. Because they are allocated |
one-by-one, each must carry its own prev_foot field, which is |
also used to hold the offset this chunk has within its mmapped |
region, which is needed to preserve alignment. Each mmapped |
chunk is trailed by the first two fields of a fake next-chunk |
for sake of usage checks. |

When chunks are not in use, they are treated as nodes of either |
lists or trees. |
"Small" chunks are stored in circular doubly-linked lists, and look |
like this: |
chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Size of previous chunk | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
`head:' | Size of chunk, in bytes |P| |
mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Forward pointer to next chunk in list | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Back pointer to previous chunk in list | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Unused space (may be 0 bytes long) . |
. . |
. | |
nextchunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
`foot:' | Size of chunk, in bytes | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
Larger chunks are kept in a form of bitwise digital trees (aka |
tries) keyed on chunksizes. Because malloc_tree_chunks are only for |
free chunks greater than 256 bytes, their size doesn't impose any |
constraints on user chunk sizes. Each node looks like: |
chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Size of previous chunk | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
`head:' | Size of chunk, in bytes |P| |
mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Forward pointer to next chunk of same size | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Back pointer to previous chunk of same size | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Pointer to left child (child[0]) | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Pointer to right child (child[1]) | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| Pointer to parent | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
| bin index of this chunk | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |

`foot:' | Size of chunk, in bytes | |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |
Each tree holding treenodes is a tree of unique chunk sizes. Chunks |
of the same size are arranged in a circularly-linked list, with only |
the oldest chunk (the next to be used, in our FIFO ordering) |
actually in the tree. (Tree members are distinguished by a non-null |
parent pointer.) If a chunk with the same size an an existing node |
is inserted, it is linked off the existing node using pointers that |
work in the same way as fd/bk pointers of small chunks. |
Each tree contains a power of 2 sized range of chunk sizes (the |
smallest is 0x100 <= x < 0x180), which is is divided in half at each |
tree level, with the chunks in the smaller half of the range (0x100 |
<= x < 0x140 for the top nose) in the left subtree and the larger |
half (0x140 <= x < 0x180) in the right subtree. This is, of course, |
done by inspecting individual bits. |
Using these rules, each node's left subtree contains all smaller |
sizes than its right subtree. However, the node at the root of each |
subtree has no particular ordering relationship to either. (The |
dividing line between the subtree sizes is based on trie relation.) |
If we remove the last chunk of a given size from the interior of the |
tree, we need to replace it with a leaf node. The tree ordering |
rules permit a node to be replaced by any leaf below it. |
The smallest chunk in a tree (a common operation in a best-fit |
allocator) can be found by walking a path to the leftmost leaf in |
the tree. Unlike a usual binary tree, where we follow left child |
pointers until we reach a null, here we follow the right child |
pointer any time the left one is null, until we reach a leaf with |
both child pointers null. The smallest chunk in the tree will be |
somewhere along that path. |
The worst case number of steps to add, find, or remove a node is |
bounded by the number of bits differentiating chunks within |
bins. Under current bin calculations, this ranges from 6 up to 21 |
(for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case |
is of course much better. |

/* ----------------------------- Segments -------------------------------- */ |
/* |
Each malloc space may include non-contiguous segments, held in a |
list headed by an embedded malloc_segment record representing the |
top-most space. Segments also include flags holding properties of |
the space. Large chunks that are directly allocated by mmap are not |
included in this list. They are instead independently created and |
destroyed without otherwise keeping track of them. |
Segment management mainly comes into play for spaces allocated by |
MMAP. Any call to MMAP might or might not return memory that is |
adjacent to an existing segment. MORECORE normally contiguously |
extends the current space, so this space is almost always adjacent, |
which is simpler and faster to deal with. (This is why MORECORE is |
used preferentially to MMAP when both are available -- see |
sys_alloc.) When allocating using MMAP, we don't use any of the |
hinting mechanisms (inconsistently) supported in various |
implementations of unix mmap, or distinguish reserving from |
committing memory. Instead, we just ask for space, and exploit |
contiguity when we get it. It is probably possible to do |
better than this on some systems, but no general scheme seems |
to be significantly better. |
Management entails a simpler variant of the consolidation scheme |
used for chunks to reduce fragmentation -- new adjacent memory is |
normally prepended or appended to an existing segment. However, |
there are limitations compared to chunk consolidation that mostly |
reflect the fact that segment processing is relatively infrequent |
(occurring only when getting memory from system) and that we |
don't expect to have huge numbers of segments: |
* Segments are not indexed, so traversal requires linear scans. (It |
would be possible to index these, but is not worth the extra |
overhead and complexity for most programs on most platforms.) |
* New segments are only appended to old ones when holding top-most |
memory; if they cannot be prepended to others, they are held in |
different segments. |
Except for the top-most segment of an mstate, each segment record |
is kept at the tail of its segment. Segments are added by pushing |
segment records onto the list headed by &mstate.seg for the |
containing mstate. |
Segment flags control allocation/merge/deallocation policies: |
* If EXTERN_BIT set, then we did not allocate this segment, |
and so should not try to deallocate or merge with others. |
(This currently holds only for the initial segment passed |
into create_mspace_with_base.) |
* If IS_MMAPPED_BIT set, the segment may be merged with |
other surrounding mmapped segments and trimmed/de-allocated |
using munmap. |
* If neither bit is set, then the segment was obtained using |
MORECORE so can be merged with surrounding MORECORE'd segments |
and deallocated/trimmed using MORECORE with negative arguments. |

/* ---------------------------- malloc_state ----------------------------- */ |
/* |
A malloc_state holds all of the bookkeeping for a space. |
The main fields are: |
Top |
The topmost chunk of the currently active segment. Its size is |
cached in topsize. The actual size of topmost space is |
topsize+TOP_FOOT_SIZE, which includes space reserved for adding |
fenceposts and segment records if necessary when getting more |
space from the system. The size at which to autotrim top is |
cached from mparams in trim_check, except that it is disabled if |
an autotrim fails. |
Designated victim (dv) |
This is the preferred chunk for servicing small requests that |
don't have exact fits. It is normally the chunk split off most |
recently to service another small request. Its size is cached in |
dvsize. The link fields of this chunk are not maintained since it |
is not kept in a bin. |
SmallBins |
An array of bin headers for free chunks. These bins hold chunks |
with sizes less than MIN_LARGE_SIZE bytes. Each bin contains |
chunks of all the same size, spaced 8 bytes apart. To simplify |
use in double-linked lists, each bin header acts as a malloc_chunk |
pointing to the real first node, if it exists (else pointing to |
itself). This avoids special-casing for headers. But to avoid |
waste, we allocate only the fd/bk pointers of bins, and then use |
repositioning tricks to treat these as the fields of a chunk. |
TreeBins |
Treebins are pointers to the roots of trees holding a range of |
sizes. There are 2 equally spaced treebins for each power of two |
from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything |
larger. |
Bin maps |
There is one bit map for small bins ("smallmap") and one for |
treebins ("treemap). Each bin sets its bit when non-empty, and |
clears the bit when empty. Bit operations are then used to avoid |
bin-by-bin searching -- nearly all "search" is done without ever |
looking at bins that won't be selected. The bit maps |
conservatively use 32 bits per map word, even if on 64bit system. |
For a good description of some of the bit-based techniques used |
here, see Henry S. Warren Jr's book "Hacker's Delight" (and |
supplement at http://hackersdelight.org/). Many of these are |
intended to reduce the branchiness of paths through malloc etc, as |
well as to reduce the number of memory locations read or written. |
Segments |
A list of segments headed by an embedded malloc_segment record |
representing the initial space. |
Address check support |
The least_addr field is the least address ever obtained from |
MORECORE or MMAP. Attempted frees and reallocs of any address less |
than this are trapped (unless INSECURE is defined). |
Magic tag |
A cross-check field that should always hold same value as mparams.magic. |
Flags |
Bits recording whether to use MMAP, locks, or contiguous MORECORE |
Statistics |
Each space keeps track of current and maximum system memory |
obtained via MORECORE or MMAP. |
Locking |
If USE_LOCKS is defined, the "mutex" lock is acquired and released |
around every public call using this mspace. |

/* |
For security, the main invariant is that malloc/free/etc never |
writes to a static address other than malloc_state, unless static |
malloc_state itself has been corrupted, which cannot occur via |
malloc (because of these checks). In essence this means that we |
believe all pointers, sizes, maps etc held in malloc_state, but |
check all of those linked or offsetted from other embedded data |
structures. These checks are interspersed with main code in a way |
that tends to minimize their run-time cost. |
When FOOTERS is defined, in addition to range checking, we also |
verify footer fields of inuse chunks, which can be used guarantee |
that the mstate controlling malloc/free is intact. This is a |
streamlined version of the approach described by William Robertson |
et al in "Run-time Detection of Heap-based Overflows" LISA'03 |
http://www.usenix.org/events/lisa03/tech/robertson.html The footer |
of an inuse chunk holds the xor of its mstate and a random seed, |
that is checked upon calls to free() and realloc(). This is |
(probablistically) unguessable from outside the program, but can be |
computed by any code successfully malloc'ing any chunk, so does not |
itself provide protection against code that has already broken |
security through some other means. Unlike Robertson et al, we |
always dynamically check addresses of all offset chunks (previous, |
next, etc). This turns out to be cheaper than relying on hashes. |

Unlink steps: |
1. If x is a chained node, unlink it from its same-sized fd/bk links |
and choose its bk node as its replacement. |
2. If x was the last node of its size, but not a leaf node, it must |
be replaced with a leaf node (not merely one with an open left or |
right), to make sure that lefts and rights of descendents |
correspond properly to bit masks. We use the rightmost descendent |
of x. We could use any other leaf, but this is easy to locate and |
tends to counteract removal of leftmosts elsewhere, and so keeps |
paths shorter than minimally guaranteed. This doesn't loop much |
because on average a node in a tree is near the bottom. |
3. If x is the base of a chain (i.e., has parent links) relink |
x's parent and children to x's replacement (or null if none). |

2. If it is big enough, use the dv chunk, which is normally the |
chunk adjacent to the one used for the most recent small request. |
3. If one exists, split the smallest available chunk in a bin, |

4. If it is big enough, use the top chunk. |
5. If available, get memory from system and use it |
Otherwise, for a large request: |
1. Find the smallest available binned chunk that fits, and use it |
if it is better fitting than dv chunk, splitting if necessary. |
2. If better fitting than any binned chunk, use the dv chunk. |
3. If it is big enough, use the top chunk. |
4. If request size >= mmap threshold, try to directly mmap this chunk. |
5. If available, get memory from system and use it |

/* -------------------- Alternative MORECORE functions ------------------- */ |

Guidelines for creating a custom version of MORECORE: |
* For best performance, MORECORE should allocate in multiples of pagesize. |
* MORECORE may allocate more memory than requested. (Or even less, |
but this will usually result in a malloc failure.) |
* MORECORE must not allocate memory when given argument zero, but |
instead return one past the end address of memory from previous |
nonzero call. |
* For best performance, consecutive calls to MORECORE with positive |
arguments should return increasing addresses, indicating that |
space has been contiguously extended. |
* Even though consecutive calls to MORECORE need not return contiguous |
addresses, it must be OK for malloc'ed chunks to span multiple |
regions in those cases where they do happen to be contiguous. |
* MORECORE need not handle negative arguments -- it may instead |
just return MFAIL when given negative arguments. |
Negative arguments are always multiples of pagesize. MORECORE |
must not misinterpret negative args as large positive unsigned |
args. You can suppress all such calls from even occurring by defining |
MORECORE_CANNOT_TRIM, |
As an example alternative MORECORE, here is a custom allocator |
kindly contributed for pre-OSX macOS. It uses virtually but not |
necessarily physically contiguous non-paged memory (locked in, |
present and won't get swapped out). You can use it by uncommenting |
this section, adding some #includes, and setting up the appropriate |
defines above: |
#define MORECORE osMoreCore |
There is also a shutdown routine that should somehow be called for |
cleanup upon program exit. |
#define MAX_POOL_ENTRIES 100 |
#define MINIMUM_MORECORE_SIZE (64 * 1024U) |
static int next_os_pool; |
void *our_os_pools[MAX_POOL_ENTRIES]; |
void *osMoreCore(int size) |
{ |
void *ptr = 0; |
static void *sbrk_top = 0; |
if (size > 0) |
{ |
if (size < MINIMUM_MORECORE_SIZE) |
size = MINIMUM_MORECORE_SIZE; |
if (CurrentExecutionLevel() == kTaskLevel) |
ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0); |
if (ptr == 0) |
{ |
return (void *) MFAIL; |
} |
// save ptrs so they can be freed during cleanup |
our_os_pools[next_os_pool] = ptr; |
next_os_pool++; |
ptr = (void *) ((((size_t) ptr) + RM_PAGE_MASK) & ~RM_PAGE_MASK); |
sbrk_top = (char *) ptr + size; |
return ptr; |
} |
else if (size < 0) |
{ |
// we don't currently support shrink behavior |
return (void *) MFAIL; |
} |
else |
{ |
return sbrk_top; |
} |
} |
// cleanup any allocated memory pools |
// called as last thing before shutting down driver |
void osCleanupMem(void) |
{ |
void **ptr; |
for (ptr = our_os_pools; ptr < &our_os_pools[MAX_POOL_ENTRIES]; ptr++) |

and Anonymous. |
* Allow override of MALLOC_ALIGNMENT (Thanks to Ruud Waij for |
helping test this.) |

leads to more fragmentation in some programs and doesn't |
seem to help in any others. |
* Collect all cases in malloc requiring system memory into sysmalloc |
* Use mmap as backup to sbrk |
* Place all internal state in malloc_state |
* Introduce fastbins (although similar to 2.5.1) |

usage of 'assert' in non-WIN32 code |
* Improve WIN32 'sbrk()' emulation's 'findRegion()' routine to |
avoid infinite loop |
* Always call 'fREe()' rather than 'free()' |

* removed potential for odd address access in prev_chunk |
* removed dependency on getpagesize.h |
* misc cosmetics and a bit more internal documentation |
* anticosmetics: mangled names in macros to evade debugger strangeness |
* tested on sparc, hp-700, dec-mips, rs6000 |
with gcc & native cc (hp, dec only) allowing |
Detlefs & Zorn comparison study (in SIGPLAN Notices.) |
Trial version Fri Aug 28 13:14:29 1992 Doug Lea (dl at g.oswego.edu) |
* Based loosely on libg++-1.2X malloc. (It retains some of the overall |
structure of old version, but most details differ.) |
