NAME
mallopt - set memory allocation parameters
SYNOPSIS
#include <malloc.h>
int mallopt(int param, int value);
DESCRIPTION
The
mallopt()
function adjusts parameters that control the behavior of the
memory-allocation functions (see
malloc(3)).
The
param
argument specifies the parameter to be modified, and
value
specifies the new value for that parameter.
The following values can be specified for
param:
- M_CHECK_ACTION
-
Setting this parameter controls how glibc responds when various kinds
of programming errors are detected (e.g., freeing the same pointer twice).
The 3 least significant bits (2, 1, and 0) of the value assigned
to this parameter determine the glibc behavior, as follows:
-
- Bit 0
-
If this bit is set, then print a one-line message on
stderr
that provides details about the error.
The message starts with the string "*** glibc detected ***",
followed by the program name,
the name of the memory-allocation function in which the error was detected,
a brief description of the error,
and the memory address where the error was detected.
- Bit 1
-
If this bit is set, then,
after printing any error message specified by bit 0,
the program is terminated by calling
abort(3).
In glibc versions since 2.4,
if bit 0 is also set,
then, between printing the error message and aborting,
the program also prints a stack trace in the manner of
backtrace(3),
and prints the process's memory mapping in the style of
/proc/[pid]/maps
(see
proc(5)).
- Bit 2 (since glibc 2.4)
-
This bit has an effect only if bit 0 is also set.
If this bit is set,
then the one-line message describing the error is simplified
to contain just the name of the function where the error
was detected and the brief description of the error.
-
The remaining bits in
value
are ignored.
-
Combining the above details,
the following numeric values are meaningful for
M_CHECK_ACTION:
-
- 0
-
Ignore error conditions; continue execution (with undefined results).
- 1
-
Print a detailed error message and continue execution.
- 2
-
Abort the program.
- 3
-
Print detailed error message, stack trace, and memory mappings,
and abort the program.
- 5
-
Print a simple error message and continue execution.
- 7
-
Print simple error message, stack trace, and memory mappings,
and abort the program.
-
Since glibc 2.3.4, the default value for the
M_CHECK_ACTION
parameter is 3.
In glibc version 2.3.3 and earlier, the default value is 1.
-
Using a nonzero
M_CHECK_ACTION
value can be useful because otherwise a crash may happen much later,
and the true cause of the problem is then very hard to track down.
- M_MMAP_MAX
-
This parameter specifies the maximum number of allocation requests that
may be simultaneously serviced using
mmap(2).
This parameter exists because some systems have a limited number
of internal tables for use by
mmap(2),
and using more than a few of them may degrade performance.
-
The default value is 65,536,
a value which has no special significance and
which servers only as a safeguard.
Setting this parameter to 0 disables the use of
mmap(2)
for servicing large allocation requests.
- M_MMAP_THRESHOLD
-
For allocations greater than or equal to the limit specified (in bytes) by
M_MMAP_THRESHOLD
that can't be satisfied from the free list,
the memory-allocation functions employ
mmap(2)
instead of increasing the program break using
sbrk(2).
-
Allocating memory using
mmap(2)
has the significant advantage that the allocated memory blocks
can always be independently released back to the system.
(By contrast,
the heap can be trimmed only if memory is freed at the top end.)
On the other hand, there are some disadvantages to the use of
mmap(2):
deallocated space is not placed on the free list
for reuse by later allocations;
memory may be wasted because
mmap(2)
allocations must be page-aligned;
and the kernel must perform the expensive task of zeroing out
memory allocated via
mmap(2).
Balancing these factors leads to a default setting of 128*1024 for the
M_MMAP_THRESHOLD
parameter.
-
The lower limit for this parameter is 0.
The upper limit is
DEFAULT_MMAP_THRESHOLD_MAX:
512*1024 on 32-bit systems or
4*1024*1024*sizeof(long)
on 64-bit systems.
-
Note:
Nowadays, glibc uses a dynamic mmap threshold by default.
The initial value of the threshold is 128*1024,
but when blocks larger than the current threshold and less than or equal to
DEFAULT_MMAP_THRESHOLD_MAX
are freed,
the threshold is adjusted upward to the size of the freed block.
When dynamic mmap thresholding is in effect,
the threshold for trimming the heap is also dynamically adjusted
to be twice the dynamic mmap threshold.
Dynamic adjustment of the mmap threshold is disabled if any of the
M_TRIM_THRESHOLD,
M_TOP_PAD,
M_MMAP_THRESHOLD,
or
M_MMAP_MAX
parameters is set.
- M_MXFAST (since glibc 2.3)
-
Set the upper limit for memory allocation requests that are satisfied
using "fastbins".
(The measurement unit for this parameter is bytes.)
Fastbins are storage areas that hold deallocated blocks of memory
of the same size without merging adjacent free blocks.
Subsequent reallocation of blocks of the same size can be handled
very quickly by allocating from the fastbin,
although memory fragmentation and the overall memory footprint
of the program can increase.
The default value for this parameter is
64*sizeof(size_t)/4
(i.e., 64 on 32-bit architectures).
The range for this parameter is 0 to
80*sizeof(size_t)/4.
Setting
M_MXFAST
to 0 disables the use of fastbins.
- M_PERTURB (since glibc 2.4)
-
If this parameter is set to a nonzero value,
then bytes of allocated memory (other than allocations via
calloc(3))
are initialized to the complement of the value
in the least significant byte of
value,
and when allocated memory is released using
free(3),
the freed bytes are set to the least significant byte of
value.
This can be useful for detecting errors where programs
incorrectly rely on allocated memory being initialized to zero,
or reuse values in memory that has already been freed.
- M_TOP_PAD
-
This parameter defines the amount of padding to employ when calling
sbrk(2)
to modify the program break.
(The measurement unit for this parameter is bytes.)
This parameter has an effect in the following circumstances:
-
- *
-
When the program break is increased, then
M_TOP_PAD
bytes are added to the
sbrk(2)
request.
- *
-
When the heap is trimmed as a consequence of calling
free(3)
(see the discussion of
M_TRIM_THRESHOLD)
this much free space is preserved at the top of the heap.
-
In either case,
the amount of padding is always rounded to a system page boundary.
-
Modifying
M_TOP_PAD
is a trade-off between increasing the number of system calls
(when the parameter is set low)
and wasting unused memory at the top of the heap
(when the parameter is set high).
-
The default value for this parameter is 128*1024.
- M_TRIM_THRESHOLD
-
When the amount of contiguous free memory at the top of the heap
grows sufficiently large,
free(3)
employs
sbrk(2)
to release this memory back to the system.
(This can be useful in programs that continue to execute for
a long period after freeing a significant amount of memory.)
The
M_TRIM_THRESHOLD
parameter specifies the minimum size (in bytes) that
this block of memory must reach before
sbrk(2)
is used to trim the heap.
-
The default value for this parameter is 128*1024.
Setting
M_TRIM_THRESHOLD
to -1 disables trimming completely.
-
Modifying
M_TRIM_THRESHOLD
is a trade-off between increasing the number of system calls
(when the parameter is set low)
and wasting unused memory at the top of the heap
(when the parameter is set high).
Environment variables
A number of environment variables can be defined
to modify some of the same parameters as are controlled by
mallopt().
Using these variables has the advantage that the source code
of the program need not be changed.
To be effective, these variables must be defined before the
first call to a memory-allocation function.
(If the same parameters are adjusted via
mallopt(),
then the
mallopt()
settings take precedence.)
For security reasons,
these variables are ignored in set-user-ID and set-group-ID programs.
The environment variables are as follows
(note the trailing underscore at the end of the name of each variable):
- MALLOC_CHECK_
-
This environment variable controls the same parameter as
mallopt()
M_CHECK_ACTION.
If this variable is set to a nonzero value,
then a special implementation of the memory-allocation functions is used.
(This is accomplished using the
malloc_hook(3)
feature.)
This implementation performs additional error checking,
but is slower
than the standard set of memory-allocation functions.
(This implementation does not detect all possible errors;
memory leaks can still occur.)
-
The value assigned to this environment variable should be a single digit,
whose meaning is as described for
M_CHECK_ACTION.
Any characters beyond the initial digit are ignored.
-
For security reasons, the effect of
MALLOC_CHECK_
is disabled by default for set-user-ID and set-group-ID programs.
However, if the file
/etc/suid-debug
exists (the content of the file is irrelevant), then
MALLOC_CHECK_
also has an effect for set-user-ID and set-group-ID programs.
- MALLOC_MMAP_MAX_
-
Controls the same parameter as
mallopt()
M_MMAP_MAX.
- MALLOC_MMAP_THRESHOLD_
-
Controls the same parameter as
mallopt()
M_MMAP_THRESHOLD.
- MALLOC_PERTURB_
-
Controls the same parameter as
mallopt()
M_PERTURB.
- MALLOC_TRIM_THRESHOLD_
-
Controls the same parameter as
mallopt()
M_TRIM_THRESHOLD.
- MALLOC_TOP_PAD_
-
Controls the same parameter as
mallopt()
M_TOP_PAD.
RETURN VALUE
On success,
mallopt()
returns 1.
On error, it returns 0.
ERRORS
On error,
errno
is
not
set.
CONFORMING TO
This function is not specified by POSIX or the C standards.
A similar function exists on many System V derivatives,
but the range of values for
param
varies across systems.
The SVID defined options
M_MXFAST,
M_NLBLKS,
M_GRAIN,
and
M_KEEP,
but only the first of these is implemented in glibc.
BUGS
Specifying an invalid value for
param
does not generate an error.
A calculation error within the glibc implementation means that
a call of the form:
mallopt(M_MXFAST, n)
does not result in fastbins being employed for all allocations of size up to
n.
To ensure desired results,
n
should be rounded up to the next multiple greater than or equal to
(2k+1)*sizeof(size_t),
where
k
is an integer.
If
mallopt()
is used to set
M_PERTURB,
then, as expected, the bytes of allocated memory are initialized
to the complement of the byte in
value,
and when that memory is freed,
the bytes of the region are initialized to the byte specified in
value.
However, there is an
off-by-sizeof(size_t)
error in the implementation:
instead of initializing precisely the block of memory
being freed by the call
free(p),
the block starting at
p+sizeof(size_t)
is initialized.
EXAMPLE
The program below demonstrates the use of
M_CHECK_ACTION.
If the program is supplied with an (integer) command-line argument,
then that argument is used to set the
M_CHECK_ACTION
parameter.
The program then allocates a block of memory,
and frees it twice (an error).
The following shell session shows what happens when we run this program
under glibc, with the default value for
M_CHECK_ACTION:
$ ./a.out
main(): returned from first free() call
*** glibc detected *** ./a.out: double free or corruption (top): 0x09d30008 ***
======= Backtrace: =========

Aborted (core dumped)
The following runs show the results when employing other values for
M_CHECK_ACTION:
$ ./a.out 1 # Diagnose error and continue
main(): returned from first free() call
*** glibc detected *** ./a.out: double free or corruption (top): 0x09cbe008 ***
main(): returned from second free() call

main(): returned from first free() call
Aborted (core dumped)
$ ./a.out 0 # Ignore error and continue
main(): returned from first free() call
main(): returned from second free() call
The next run shows how to set the same parameter using the
MALLOC_CHECK_
environment variable:
$ MALLOC_CHECK_=1 ./a.out
main(): returned from first free() call
*** glibc detected *** ./a.out: free(): invalid pointer: 0x092c2008 ***

To develop an efficient Q and A engine to answer the natural language query for INDIAN HISTORY in one sentence rather than providing the reference links for the answer.
The efficiency of the Engine will be calculated in terms of processing time and specificness of the answer. Speciality of our Q and A enigne is that the domain of the questions asked will be INDIAN HISTORY which is Restricted domain.
User can ask Factoid Questions which include who, when, where, what, which. The data source that will be used is Unstructured one like web pages, books, articles, etc.
My COntribution: Learning about Natural language processing and working of an QAEngine. Also trying to work on Console.
My Contribution: Developing Front-end of the Engine and study regarding working of OCR and Elastic Search
Check it outThe project includes the business plan for a small venture. It is basically an idea of platform based business which connects costumers who require ayurvedic medicines and the suppliers. It also had additional features of onnline consultancy with doctor.

READ_FILE_TEXT
Function
Reads the contents of a text file and returns it as a single string representing the whole file.
Syntax
READ_FILE_TEXT(file-path, [file-encoding])
Arguments
- file-path (string expression)
The absolute path to the text file to read.
- file-encoding (integer expression, optional, 0-65535, default: 0)
Indicates the text encoding to use when
reading the file. Specify 0 to detect the encoding automatically. Any nonzero integer is treated as a Windows code page
number.
Return Value
Text.
Examples
DECLARE @data = READ_FILE_TEXT('C:\MyFile.txt');
Reads the contents of "MyFile.txt" into a text
variable called @data
. Because the file-encoding parameter is not specified, the UTF-8 encoding
is used to read the file.
SELECT READ_FILE_TEXT('C:\ShiftJIS.txt', 932) AS data;
Produces a 1-row query result containing
the contents of "ShiftJIS.txt", which is read using the Japanese Shift-JIS encoding (code page 932).

This Week in Rust
Welcome to another issue of This Week in Rust. We’re gearing up for a 0.8 release, tentatively planned for Thursday. Additionally, a huge welcome of Alex Crichton to the Rust team! He’s been doing some great work, it’s wonderful to have another full-time Rust dev.
What’s cooking in master?
There were 86 PRs merged this week.
rustdoc_ng
rustdoc_ng was merged into mainline and enabled as the new rustdoc, in time for 0.8. This makes me incredibly happy, as it marks the conclusion of my quest to a better rustdoc. Not to say that rustdoc is finished or perfect, but it’s already much better than the old rustdoc. My sincere thanks go to Jordi Boggiano (Seldaek), who worked unceasingly to create a beautiful, usable frontend, and to Meret Vollenweider (meretv) for donating her amazing design skills. Also thanks to Huon Wilson (dbaupp) for moral support and creating the awesome DocFolder interface that passes over the documentation use. And, of course, to Alex Crichton, who pushed these past few days to port the static site generator to Rust and to integrate it into the build system.
The new docs have replaced the old docs. You can view them on the Rust
website. Still to-do
is proper cross-crate doc hyperlinking. To run it on your own crate, build a
recent Rust and do rustdoc html path/to/your/crate.rs
. It will eventually be
integrated into rustpkg
.
Breaking changes
extra::par
has been removed.- Some unsound functional struct updates (FSU,
{a: 5, ..b}
) are now disallowed. --cfg debug
is no longer required. If you want to disable debug logging, use--cfg ndebug
.- The various uses of
NaN
are now lowercased tonan
. std::util::unreachable
has been removed in factor of theunreachable!
macro.extra::future
has been cleaned up a bit, including some method shuffling/renames.extra::getopts
has been cleaned up as well, with most free functions now being methods.- The
from_str
methods in the numeric modules have been removed in favor of the FromStr trait and thefrom_str
free function in the prelude. Same forfrom_str_radix
. - The
Drop
trait now uses&mut self
, as part of the transition to by-value drops. extra::json
uses a different encoding when encoding/decoding enums, so any Rust-generated JSON before this patch will now be rejected by the decoder.
Other changes
- debuginfo now works for recursive types.
- You can now pass parameters to
the generated test with
rust test
. extern fn
s from external crates now use the declared ABI, rather than assuming cdecl.CString
has gained anas_str
method.- Some overflow bugs in
vec
andstr
have been fixed. statics
are now properly inlined cross-crate.- The
bytes!
macro’s error reporting has been tightened up to make it more obvious where the error is. rustpkg init
has been added, to create a new workspace.- File IO in newrt has been massively reworked and is much more complete than the oldrt.
- The exact meaning of “unsafety” is now documented.
\0
escapes in strings is now supported.rustpkg
now thinks in terms of crates, not packages, to you can now have multiple crates in a single package and have things work correctly.- newrt has pipes and process support now.
format!
now allows trailing commas in its arguments.- The lexer now throws vastly better errors.
Weekly Meeting
The weekly
meeting
discussed quite a bit, most interesting to me was the crypto discussion,
putting macro_rules!
behind an experimental flag, and the default arguments
discussion.
Project announcements etc
- rustymem – a pure-rust memcached library.
- “Where to learn more about Rust’s concurrency model?”
- q3 now has skeletal animation!.

Toyota Is Ending Its Weird Holdout From Racing Games
by Luke PlunkettAs one of the biggest car companies in the world, it was weird when Toyota simply stopped licensing its vehicles to racing video games back in 2017. It was even weirder that the company, despite its size, never actually explained why that decision was made.
But whatever the actual reasons for Toyota’s absence, it’s over now. Starting with the 98 Supra RZ, Toyota is back with an appearance in Forza Horizon 4:
A low-key way to announce a return, then, but also fitting given the circumstances Toyota left in the first place.


Malaysia: GDP loses momentum in Q3 – UOB
by Pablo PiovanoSenior Economist Julia Goh and Economist Loke Siew Ting at UOB Group assessed the latest release of Q3 GDP figures.
Key Quotes
“Real GDP rose at a slower pace of 4.4% y/y in 3Q19 (from 4.9% y/y in 2Q19), in line with market consensus but above our estimate (4.1%). Year-to-date, GDP rose 4.6% in Jan-Sep”.
“Private consumption was the prime driver, which grew 7.0% and contributed 4.1% pts to headline GDP in 3Q19. Other positive contributors were government consumption and net exports. All key sectors expanded except for mining and construction”.
“Our preliminary estimates suggest that GDP growth could pick up to 4.5% in 4Q19 with higher seasonal spending and accelerated government spending. A turnaround in the mining sector could also alleviate the drag on growth. As such, we maintain our full-year growth forecast of 4.6% in 2019 and 4.4% in 2020”.
“Given the slower trend growth below Malaysia’s potential output of 4.8% - 5.0%, we have penciled in a 25bps cut in the Overnight Policy Rate (OPR) to 2.75% in 1Q20. This is to safeguard domestic growth amid lingering trade uncertainties and muted investments”.

| get_historical_precip {rWBclimate} | R Documentation |
The Climate Data API provides access to historical precipitation data. These data are separate from the outputs of the GCMs, and they are based on gridded climatologies from the Climate Research Unit.
get_historical_precip(locator, time_scale)
locator |
The ISO3 country code that you want data about. (http://unstats.un.org/unsd/methods/m49/m49alpha.htm) or the basin ID [1-468]. This can be a vector of all basins or all countries. |
time_scale |
The time scale you want to return values on. Must be "month", "year" or "decade" |
The historical period for country is 1901 - 2009, and 1960 - 2009 for basin. The time_scale parameter returns a different number of variables depending on the input timescale. Month will return 12 values, a historical average for that month across all years. Year will return yearly averages for each year, and decade will return decade averages.
