/*
Redis is an in memory DB. We need to share the redis database with a quasi-forked process so that we can do the RDB and AOF saves
without halting the main redis process, or crashing due to code that was never designed to be thread safe. Essentially we need to
replicate the COW behavior of fork() on Windows, but we don't actually need a complete fork() implementation. A complete fork()
implementation would require subsystem level support to make happen. The following is required to make this quasi-fork scheme work:
DLMalloc (http://g.oswego.edu/dl/html/malloc.html):
- replaces malloc/realloc/free, either by manual patching of the zmalloc code in Redis or by patching the CRT routines at link time
- partitions space into segments that it allocates from (currently configured as 64MB chunks)
- we map/unmap these chunks as requested into a memory map (unmapping allows the system to decide how to reduce the physical memory
pressure on system)
DLMallocMemoryMap:
- An uncomitted memory map whose size is the total physical memory on the system less some memory for the rest of the system so that
we avoid excessive swapping.
- This is reserved high in VM space so that it can be mapped at a specific address in the child qforked process (ASLR must be
disabled for these processes)
- This must be mapped in exactly the same virtual memory space in both forker and forkee.
QForkConrolMemoryMap:
- contains a map of the allocated segments in the DLMallocMemoryMap
- contains handles for inter-process synchronization
- contains pointers to some of the global data in the parent process if mapped into DLMallocMemoryMap, and a copy of any other
required global data
QFork process:
- a copy of the parent process with a command line specifying QFork behavior
- when a COW operation is requested via an event signal
- opens the DLMAllocMemoryMap with PAGE_WRITECOPY
- reserve space for DLMAllocMemoryMap at the memory location specified in ControlMemoryMap
- locks the DLMalloc segments as specified in QForkConrolMemoryMap
- maps global data from the QForkConrolMEmoryMap into this process
- executes the requested operation
- unmaps all the mm views (discarding any writes)
- signals the parent when the operation is complete
How the parent invokes the QFork process:
- protects mapped memory segments with VirtualProtect using PAGE_WRITECOPY (both the allocated portions of DLMAllocMemoryMap and
the QForkConrolMemoryMap)
- QForked process is signaled to process command
- Parent waits (asynchronously) until QForked process signals that operation is complete, then as an atomic operation:
- signals and waits for the forked process to terminate
- resotres protection status on mapped blocks

Default header file for malloc-2.8.x, written by Doug Lea
and released to the public domain, as explained at
http://creativecommons.org/publicdomain/zero/1.0/
This header is for ANSI C/C++ only. You can set any of
the following #defines before including:
* If USE_DL_PREFIX is defined, it is assumed that malloc.c
was also compiled with this option, so all routines
have names starting with "dl".
* If HAVE_USR_INCLUDE_MALLOC_H is defined, it is assumed that this
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
declarations should be compatible with system versions
* If MSPACES is defined, declarations for mspace versions are included.

Returns a pointer to a newly allocated chunk of at least n bytes, or

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

cases less than the maximum representable value of a size_t.

Returns a pointer to a chunk of size n that contains the same data

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.

to be used as an argument to realloc is not supported.

available if n is greater than p's current allocated size, or n is
less than or equal to p's size). This may be used instead of plain
realloc if an alternative allocation strategy is needed upon failure
to expand space; for example, reallocation of a buffer that must be

these alternatives only when needed.

Using an argument of the maximum possible size_t effectively

malloc_inspect_all(void(*handler)(void *start,

Traverses the heap and calls the given handler for each managed

purposes. Traversal does not include include chunks that have been
directly memory mapped. Each reported region begins at the start
address, and continues up to but not including the end address. The
first used_bytes of the region contain allocated data. If
used_bytes is zero, the region is unallocated. The handler is
invoked with the given callback argument. If locks are defined, they
are held during the entire traversal. It is a bad idea to invoke
other malloc functions from within the handler.
For example, to count the number of in-use chunks with size greater
than 1000, you could write:
static int count = 0;
void count_chunks(void* start, void* end, size_t used, void* arg) {
if (used >= 1000) ++count;

/*
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 freed when it is no longer needed. This can be
done all at once using bulk_free.
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 freed when it is no longer needed. This can be
done all at once using bulk_free.
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]);
// ...

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.

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
(normally sbrk) outside of malloc.
