The Maeslantkering protects the harbor of Rotterdam against the North Sea. When the sea level rises the harbor is at danger. If the water gets too high, the Maeslantkering must close. However, the failure probability is too high. To reduce the chance of failure without making the Maeslantkering more unsafe, a Proof-of-Concept must come. Our team is tasked with this project. Our mission is to create a working scale replica that mimics the functionality of the Maeslantkering.
Build a Proof-of-Concept for the Maeslantkering and present the demo in 3 weeks.
The team was drafted by the teacher Marco van den Boogaard on 22 November 2017. Five individuals were chosen based on their specialization. The team then made agreements and a project proposal together.


The practice is known to have existed in the Tang Dynasty, when Empress Wu Zetian sent a pair of pandas to the Japanese emperor.
The first living panda to go to the West was Su Lin. Ruth Harkness, an American fashion designer, registered the 3-month-pld baby panda as a puppy when boarding her ship back to America.
Song May-Ling (Madame Chiang Kai-shek) gave a pair of pandas to America in appreciation of their help to China. It was the first time China delivered a live panda in the government’s name. Chiang’s government presented 14 pandas to various western countries.
Panda ‘Lien Ho’ and a Chinese biologist arrived in London to rapturous enthusiasm. Realizing the diplomatic goodwill value of pandas, they have since mostly turned up in the west as political gifts.
After Mao Zedong declared the creation of the People’s Republic of China, the giant panda was gifted exclusively to allied socialist states. Appreciating how scarce wild giant pandas had become, poaching was strictly prohibited.
The Panda’s diplomatic career formally took off in the 1950s. Twenty-three giant pandas were sent abroad as state gifts to nice countries, while an additional panda was exchanged for three giraffes, two rhinos, two hippos and two zebras with an Austrian animal dealer.
Five of the 23 panda ambassadors are still alive, including one in Japan, three in Mexico and one in Germany. These countries have ownership of the offspring.
From 1990, the China Wildlife Conservation Association (CWCA) and China Zoological Association, reached an agreement with the International Wildlife Conservation Agency to Loan giant pandas for cooperative research. Pandas now go abroad for fees, which vary according to the receiving country.

I spent time to configure gitlab runners in kubernetes. Until now we had runners on EC2 which worked well. However, it was bugging me that those ec2 instances were under utilze. I wanted to configure gitlab runners in kubernetes to ensure that we are not wasting resources. Gitlab already have extensive documentation on the topic, mainly I will refer to pointers in gitlab documentation.
This is straight forward and gitlab has a detailed documentation, When you are adding an existing cluster Use "More Information" link to get more information on the topic. This gitlab kubernetes documentation has additional information.
As shown in here, you will need gitlab url
and runner registration token
. Also, you need helm
configured on the system. helm
uses values.yaml
to pass configuration options to gitlab runners. A values.yaml
exapmle is available in above document, also you can download from here. After download, uncomment gitlabUrl
and runnerRegistrationToken
to add your values. Please read above document to find out information on other configuration options. After modifying values.yaml
run following commands.
helm init
helm install --namespace gitlab-managed-apps --name gitlab-runner -f values.yaml gitlab/gitlab-runner
after this step, you can see kubernetes runner appear in Settings -> CI/CD -> Runners
section.

JDO manages the lifecycle of an object, from creation (Transient) through to persistence in the datastore (Hollow, Persistent Clean) and all of the various states between these. The transition between these states are achieved by using methods on the Persistence Manager such as makePersistent(), makeTransient(), deletePersistent(), and by commiting the changes made by these operations, or by rolling them back.
The various lifecycle states supported by JDO are shown below.
| Name | Description |
|---|---|
Transient |
Any object created by the developer that do are not persisted. These don’t have a JDO identity. |
Persistent New |
Any object that is newly persisted in the current transaction. A JDO identity has been assigned to these objects. |
Persistent Dirty |
Any persistent object that has been changed in the current transaction. |
Hollow |
Any persistent object that represents data in the datastore, but whose values are not in the instance. |
Persistent Clean |
Any persistent object that represents data in the datastore, and whose values have not been changed in the current transaction. |
Persistent Deleted |
Any persistent object that represents data in the datastore, and that has been deleted in the current transaction. |
Persistent New Deleted |
Any object that have been newly made persistent and then deleted in the same current transaction. |
Persistent Non transactional |
Any persistent object that represents data in the datastore, whose values are loaded but not transactionally consistent. |
Persistent Non transactional Dirty |
Any persistent object that represents data in the datastore, whose values are loaded but not transactionally consistent, and that has been modified. |
Transient Clean |
Any transient object that represents a transactional instance whose values have not been changed in the current transaction. |
Transient Dirty |
Any transient object that represents a transactional instance whose values have been changed in the current transaction. |
Detached Clean |
Any detached object that represents a persistent instance whose values have not been changed since detaching. |
Detached Dirty |
Any detached object that represents a persistent instance whose values have been changed since detaching. |
JDO provides a class JDOHelper that allows you to interrogate the object state via its attributes (isPersistent(), isDeleted(), etc). In JDO 2.1 for JDKs 1.5+ JDOHelper is extended to also provide a method that gives the full object state.
ObjectState state = JDOHelper.getObjectState(obj);
The most basic thing you can do with JDO is persist an object. The following code is an example of how you can do this
Transaction tx=pm.currentTransaction(); try { tx.begin(); Product product = new Product("Plate", 9.99); pm.makePersistent(product); tx.commit(); } finally { if (tx.isActive()) { tx.rollback(); } }
The Product object progresses from Transient (initial, unpersisted state), through to Persistent New, and then finally to Hollow when it reaches the data store (after the "commit"). If the persist failed, it would "rollback" and hence end up in the same state as when it started. The following diagram shows this graphically
When you have persisted objects you need to update them. The following code is an example of how you can do this
Transaction tx=pm.currentTransaction(); try { tx.begin(); String product_name = product.getName(); ... product.setPrice(7.50); tx.commit(); } finally { if (tx.isActive()) { tx.rollback(); } }
The Product object starts off in Hollow state and progresses to Persistent Clean when the user requires to read from it. It then migrates to Persistent Dirty when the price is updated. Finally it returns to Hollow when the user commits/rolls back the transaction. The following diagram shows this graphically
When you no longer need an object persisted, you can delete it. The following code is an example of how you can do this
Transaction tx=pm.currentTransaction(); try { tx.begin(); String product_name = product.getName(); ... pm.deletePersistent(product); tx.commit(); } finally { if (tx.isActive()) { tx.rollback(); } }
The Product object starts off in Hollow state and progresses to Persistent Clean when the user requires to read from it. It then migrates to Persistent Deleted when the deletePersistent() called. Finally it either progresses to Transient when commit is called, or returns to Hollow if it is rolled back. The following diagram shows this graphically


The HeapBuf manager provides functions to allocate and free storage from a
heap of type HeapBuf which inherits from IHeap. HeapBuf manages a single
fixed-size buffer, split into equally sized allocable blocks.
The HeapBuf manager is intended as a very fast and deterministic memory
manager which can only allocate blocks of a single size. It is ideal for
managing a heap that is only used for allocating a single type of object,
or for objects that have very similar sizes.
Allocation from and freeing to a HeapBuf instance is non-blocking and
deterministic: a call to alloc or free will always take the same amount of
time.
| struct HeapBuf_ExtendedStats |
|
Stat structure for the HeapBuf_getExtendedStats function
typedef struct HeapBuf_ExtendedStats {
UInt maxAllocatedBlocks;
UInt numAllocatedBlocks;
} HeapBuf_ExtendedStats;
FIELDS
maxAllocatedBlocks
The maximum number of blocks allocated from
this heap at any single point in time, during
the lifetime of this HeapBuf instance.
The configuration parameter
trackMaxAllocs must be set to true
for this field to have any meaning.
Otherwise, this field will be set to '0'.
numAllocatedBlocks
The total number of blocks currently
allocated in this HeapBuf instance.
| config HeapBuf_A_bufAlign // module-wide |
|
Misalligned buffer
DETAILS
This Assert is raised when the buf parameter has not been aligned
on the requested alignment.
| config HeapBuf_A_invalidAlign // module-wide |
|
Invalid alignment
extern const Assert_Id HeapBuf_A_invalidAlign;
DETAILS
This Assert is raised when the align parameter is not the default
value of zero, or a power of 2 that is greater than or equal to
the value defined by
xdc.runtime.Memory.getMaxDefaultTypeAlign.
| config HeapBuf_A_invalidBlockSize // module-wide |
|
Assert raised when the blockSize parameter is not large enough to
hold two pointers
extern const Assert_Id HeapBuf_A_invalidBlockSize;
| config HeapBuf_A_invalidBufSize // module-wide |
|
Invalid buffer size
extern const Assert_Id HeapBuf_A_invalidBufSize;
DETAILS
This Assert is raised when the bufSize parameter is too small
to handle requested blocks.
| config HeapBuf_A_invalidFree // module-wide |
|
Assert raised when an invalid free occurs
extern const Assert_Id HeapBuf_A_invalidFree;
DETAILS
This assert can be caused for the following reasons
- Passing a NULL pointer to the free.
- The block is not within the heap's buffer range. This can occur if
the block is freed to the wrong heap.
- The block is not on the proper boundary. This can occur if the
pointer returned from alloc is changed by the application and not set
back to its original value when free is called.
| config HeapBuf_A_invalidRequestedAlign // module-wide |
|
Invalid alignment parameter in the alloc
extern const Assert_Id HeapBuf_A_invalidRequestedAlign;
DETAILS
This Assert is raised when the align argument is not a power of 2 (or 0).
It is also raised if the parameter is greater the alignment
specified when creating the heap.
| config HeapBuf_A_noBlocksToFree // module-wide |
|
No allocated blocks
extern const Assert_Id HeapBuf_A_noBlocksToFree;
DETAILS
This Assert is raised when free is called and there are no blocks
allocated.
| config HeapBuf_A_nullBuf // module-wide |
|
Null buf parameter
DETAILS
This Assert is raised when the buf parameter has been omitted (null)
for a dynamic create.
| config HeapBuf_A_zeroBlocks // module-wide |
|
Assert raised when the numBlocks parameter is 0
| config HeapBuf_A_zeroBufSize // module-wide |
|
Assert raised when the bufSize parameter is 0
extern const Assert_Id HeapBuf_A_zeroBufSize;
| config HeapBuf_E_size // module-wide |
|
Raised when requested size exceeds blockSize
| config HeapBuf_trackMaxAllocs // module-wide |
|
Track maximum number of allocations
extern const Bool HeapBuf_trackMaxAllocs;
DETAILS
This will enable/disable the tracking of the maximum number of
allocations for a HeapBuf instance. This maximum refers to the "all
time" maximum number of allocations for the history of a HeapBuf
instance, not the current number of allocations.
| Module-Wide Built-Ins |
|
// Get this module's unique id
Bool HeapBuf_Module_startupDone();
// Test if this module has completed startup
// The heap from which this module allocates memory
Bool HeapBuf_Module_hasMask();
// Test whether this module has a diagnostics mask
Bits16 HeapBuf_Module_getMask();
// Returns the diagnostics mask for this module
Void HeapBuf_Module_setMask(Bits16 mask);
// Set the diagnostics mask for this module
| Instance Object Types |
|
typedef struct HeapBuf_Object HeapBuf_Object;
// Opaque internal representation of an instance object
// Client reference to an instance object
typedef struct HeapBuf_Struct HeapBuf_Struct;
// Opaque client structure large enough to hold an instance object
// Convert this instance structure pointer into an instance handle
// Convert this instance handle into an instance structure pointer
| Instance Config Parameters |
|
typedef struct HeapBuf_Params {
// Instance config-params structure
// Common per-instance configs
SizeT align;
// Alignment (in MAUs) of each block
SizeT blockSize;
// Size (in MAUs) of each block
Ptr buf;
// User supplied buffer; for dynamic creates only
// Size (in MAUs) of the entire buffer; for dynamic creates only
UInt numBlocks;
// Number of fixed-size blocks
} HeapBuf_Params;
// Initialize this config-params structure with supplier-specified defaults before instance creation
| config HeapBuf_Params.align // instance |
|
Alignment (in MAUs) of each block
DETAILS
The alignment must be a power of 2 that is greater than or equal to
the target dependent value defined by
xdc.runtime.Memory.getMaxDefaultTypeAlign. If the default value
of 0 is specified, this value will be changed to be the minimum
structure alignment requirement, as defined by
xdc.runtime.Memory.getMaxDefaultTypeAlign.
For static creates, the HeapBuf module will allocate space for the
buffer and will align it on this requested alignment.
For dynamic creates, this parameter is used solely for error checking.
The buffer provided to a dynamically created HeapBuf must be aligned
manually, and an assert will be raised if the buffer is not properly
aligned. For dynamic creates, HeapBuf will NOT adjust the buffer to
satisfy the alignment.
| config HeapBuf_Params.blockSize // instance |
|
Size (in MAUs) of each block
DETAILS
HeapBuf will round the blockSize up to the nearest multiple of the
alignment, so the actual blockSize may be larger. When creating a
HeapBuf dynamically, this needs to be taken into account to determine
the proper buffer size to pass in.
Required parameter.
The default size of the blocks is 0 MAUs.
| config HeapBuf_Params.buf // instance |
|
User supplied buffer; for dynamic creates only
DETAILS
The caller must supply the memory buffer for a dynamically created
HeapBuf to manage. The provided buffer must be aligned according to the
HeapBuf's alignment parameter. i.e., if a buffer's alignment parameter
is 128, then the buffer's start address must be a multiple of 128.
For static creates, the buffer is allocated automatically based on the
blockSize and numBlocks parameters.
This parameter is required for dynamic creates and ignored for static
creates.
| config HeapBuf_Params.bufSize // instance |
|
Size (in MAUs) of the entire buffer; for dynamic creates only
DETAILS
When dynamically creating a HeapBuf, this should be the actual size
of the memory buffer provided for HeapBuf to manage.
This parameter is used solely for error checking; an Error is raised
if the bufSize is too small for the requested blockSize and numBlocks.
Because of minimum alignment considerations, it's easy to provide too
small of a buffer to manage, and difficult to detect if it happened.
This parameter is required for dynamic creates and ignored for static
creates.
The default buffer size is 0 MAUs.
| config HeapBuf_Params.numBlocks // instance |
|
Number of fixed-size blocks
DETAILS
Required parameter.
The default number of blocks is 0.
| Runtime Instance Creation |
|
// Allocate and initialize a new instance object and return its handle
// Initialize a new instance object inside the provided structure
ARGUMENTS
params
per-instance config params, or NULL to select default values (target-domain only)
eb
active error-handling block, or NULL to select default policy (target-domain only)
DETAILS
See specific IHeap implementation for parameters used.
| Instance Deletion |
|
// Finalize and free this previously allocated instance object, setting the referenced handle to NULL
// Finalize the instance object inside the provided structure
| HeapBuf_alloc() // instance |
|
Allocates a block of memory from the heap
ARGUMENTS
handle
handle of a previously-created HeapBuf instance object
size
size (in MADUs) of the block
align
alignment (in MADUs) of the block
eb
pointer to error block
DETAILS
This method returns a block of memory from the heap.
It is called by the
xdc.runtime.Memory.alloc() function.
HeapBuf_alloc will only fail if there are no available blocks or if the
requested block size is larger than the HeapBuf's blockSize. All other
requests, regardless of size, will succeed.
HEAPBUF
All alignment is handled in the create, therefore the
align argument in alloc is ignored.
RETURNS
Returns the address of the allocated memory.
| HeapBuf_free() // instance |
|
Free a block of memory back to the heap
ARGUMENTS
handle
handle of a previously-created HeapBuf instance object
block
non-NULL address of allocated block to free
size
size (in MADUs) of the block of memory to free
DETAILS
This method gives back a block of memory to a heap.
It is called by the
xdc.runtime.Memory.free() function.
| HeapBuf_getExtendedStats() // instance |
|
Retrieves the extended statistics for a HeapBuf instance
ARGUMENTS
handle
handle of a previously-created HeapBuf instance object
stats
Location for the returned extended statistics.
DETAILS
This function retrieves the extended statistics for a HeapBuf instance.
It does not retrieve the standard xdc.runtime.Memory.Stats information.
| HeapBuf_getStats() // instance |
|
Retrieve the statistics from the heap
ARGUMENTS
handle
handle of a previously-created HeapBuf instance object
stats
non-NULL pointer to an output buffer
DETAILS
The caller passes in a pointer to a
xdc.runtime.Memory.Stats
structure and
getStats fills in this structure.
This function is called by the
xdc.runtime.Memory.getStats()
function.
| HeapBuf_isBlocking() // instance |
|
Returns whether the heap may block during an alloc() or
free()
ARGUMENTS
handle
handle of a previously-created HeapBuf instance object
HEAPBUF
This function always returns FALSE since the alloc/free
never block on a resource.
RETURNS
If the heap might block, TRUE is returned.
If the heap does not block, FALSE is returned.
| Instance Convertors |
|
// unconditionally move one level up the inheritance hierarchy
// conditionally move one level down the inheritance hierarchy; NULL upon failure
| Instance Built-Ins |
|
Int HeapBuf_Object_count();
// The number of statically-created instance objects
// The handle of the i-th statically-created instance object (array == NULL)

Stat structure for the HeapBuf_getExtendedStats function
var obj = new HeapBuf.ExtendedStats;
obj.maxAllocatedBlocks = UInt ...
obj.numAllocatedBlocks = UInt ...
FIELDS
maxAllocatedBlocks
The maximum number of blocks allocated from
this heap at any single point in time, during
the lifetime of this HeapBuf instance.
The configuration parameter
trackMaxAllocs must be set to true
for this field to have any meaning.
Otherwise, this field will be set to '0'.
numAllocatedBlocks
The total number of blocks currently
allocated in this HeapBuf instance.
C SYNOPSIS
| config HeapBuf.A_bufAlign // module-wide |
|
Misalligned buffer
msg: "buf not properly aligned"
};
DETAILS
This Assert is raised when the buf parameter has not been aligned
on the requested alignment.
C SYNOPSIS
| config HeapBuf.A_invalidAlign // module-wide |
|
Invalid alignment
msg: "align parameter must be 0 or a power of 2 >= the value of Memory_getMaxDefaultTypeAlign()"
};
DETAILS
This Assert is raised when the align parameter is not the default
value of zero, or a power of 2 that is greater than or equal to
the value defined by
xdc.runtime.Memory.getMaxDefaultTypeAlign.
C SYNOPSIS
| config HeapBuf.A_invalidBlockSize // module-wide |
|
Assert raised when the blockSize parameter is not large enough to
hold two pointers
msg: "blockSize must be large enough to hold atleast two pointers"
};
C SYNOPSIS
| config HeapBuf.A_invalidBufSize // module-wide |
|
Invalid buffer size
msg: "HeapBuf_create's bufSize parameter is invalid (too small)"
};
DETAILS
This Assert is raised when the bufSize parameter is too small
to handle requested blocks.
C SYNOPSIS
| config HeapBuf.A_invalidFree // module-wide |
|
Assert raised when an invalid free occurs
msg: "A_invalidFree: Invalid free"
};
DETAILS
This assert can be caused for the following reasons
- Passing a NULL pointer to the free.
- The block is not within the heap's buffer range. This can occur if
the block is freed to the wrong heap.
- The block is not on the proper boundary. This can occur if the
pointer returned from alloc is changed by the application and not set
back to its original value when free is called.
C SYNOPSIS
| config HeapBuf.A_invalidRequestedAlign // module-wide |
|
Invalid alignment parameter in the alloc
msg: "align parameter 1) must be 0 or a power of 2 and 2) not greater than the heaps alignment"
};
DETAILS
This Assert is raised when the align argument is not a power of 2 (or 0).
It is also raised if the parameter is greater the alignment
specified when creating the heap.
C SYNOPSIS
| config HeapBuf.A_noBlocksToFree // module-wide |
|
No allocated blocks
msg: "Cannot call HeapBuf_free when no blocks have been allocated"
};
DETAILS
This Assert is raised when free is called and there are no blocks
allocated.
C SYNOPSIS
| config HeapBuf.A_nullBuf // module-wide |
|
Null buf parameter
msg: "buf parameter cannot be null"
};
DETAILS
This Assert is raised when the buf parameter has been omitted (null)
for a dynamic create.
C SYNOPSIS
| config HeapBuf.A_zeroBlocks // module-wide |
|
Assert raised when the numBlocks parameter is 0
msg: "numBlocks cannot be zero"
};
C SYNOPSIS
| config HeapBuf.A_zeroBufSize // module-wide |
|
Assert raised when the bufSize parameter is 0
msg: "bufSize cannot be zero"
};
C SYNOPSIS
| config HeapBuf.E_size // module-wide |
|
Raised when requested size exceeds blockSize
msg: "requested size is too big: handle=0x%x, size=%u"
};
C SYNOPSIS
| config HeapBuf.trackMaxAllocs // module-wide |
|
Track maximum number of allocations
HeapBuf.trackMaxAllocs = Bool false;
DETAILS
This will enable/disable the tracking of the maximum number of
allocations for a HeapBuf instance. This maximum refers to the "all
time" maximum number of allocations for the history of a HeapBuf
instance, not the current number of allocations.
C SYNOPSIS
| metaonly config HeapBuf.common$ // module-wide |
|
Common module configuration parameters
DETAILS
All modules have this configuration parameter. Its name contains the '$'
character to ensure it does not conflict with configuration parameters
declared by the module. This allows new configuration parameters to be
added in the future without any chance of breaking existing modules.
| Instance Config Parameters |
|
var params = new HeapBuf.Params;
// Instance config-params object
params.align = SizeT 0;
// Alignment (in MAUs) of each block
params.blockSize = SizeT 0;
// Size (in MAUs) of each block
params.buf = Ptr 0;
// User supplied buffer; for dynamic creates only
params.bufSize = UArg 0;
// Size (in MAUs) of the entire buffer; for dynamic creates only
params.numBlocks = UInt 0;
// Number of fixed-size blocks
params.sectionName = String null;
// Section name for the buffer managed by the instance
| config HeapBuf.Params.align // instance |
|
Alignment (in MAUs) of each block
var params = new HeapBuf.Params;
...
params.align = SizeT 0;
DETAILS
The alignment must be a power of 2 that is greater than or equal to
the target dependent value defined by
xdc.runtime.Memory.getMaxDefaultTypeAlign. If the default value
of 0 is specified, this value will be changed to be the minimum
structure alignment requirement, as defined by
xdc.runtime.Memory.getMaxDefaultTypeAlign.
For static creates, the HeapBuf module will allocate space for the
buffer and will align it on this requested alignment.
For dynamic creates, this parameter is used solely for error checking.
The buffer provided to a dynamically created HeapBuf must be aligned
manually, and an assert will be raised if the buffer is not properly
aligned. For dynamic creates, HeapBuf will NOT adjust the buffer to
satisfy the alignment.
C SYNOPSIS
| config HeapBuf.Params.blockSize // instance |
|
Size (in MAUs) of each block
var params = new HeapBuf.Params;
...
params.blockSize = SizeT 0;
DETAILS
HeapBuf will round the blockSize up to the nearest multiple of the
alignment, so the actual blockSize may be larger. When creating a
HeapBuf dynamically, this needs to be taken into account to determine
the proper buffer size to pass in.
Required parameter.
The default size of the blocks is 0 MAUs.
C SYNOPSIS
| config HeapBuf.Params.buf // instance |
|
User supplied buffer; for dynamic creates only
var params = new HeapBuf.Params;
...
params.buf = Ptr 0;
DETAILS
The caller must supply the memory buffer for a dynamically created
HeapBuf to manage. The provided buffer must be aligned according to the
HeapBuf's alignment parameter. i.e., if a buffer's alignment parameter
is 128, then the buffer's start address must be a multiple of 128.
For static creates, the buffer is allocated automatically based on the
blockSize and numBlocks parameters.
This parameter is required for dynamic creates and ignored for static
creates.
C SYNOPSIS
| config HeapBuf.Params.bufSize // instance |
|
Size (in MAUs) of the entire buffer; for dynamic creates only
var params = new HeapBuf.Params;
...
params.bufSize = UArg 0;
DETAILS
When dynamically creating a HeapBuf, this should be the actual size
of the memory buffer provided for HeapBuf to manage.
This parameter is used solely for error checking; an Error is raised
if the bufSize is too small for the requested blockSize and numBlocks.
Because of minimum alignment considerations, it's easy to provide too
small of a buffer to manage, and difficult to detect if it happened.
This parameter is required for dynamic creates and ignored for static
creates.
The default buffer size is 0 MAUs.
C SYNOPSIS
| config HeapBuf.Params.numBlocks // instance |
|
Number of fixed-size blocks
var params = new HeapBuf.Params;
...
params.numBlocks = UInt 0;
DETAILS
Required parameter.
The default number of blocks is 0.
C SYNOPSIS
| metaonly config HeapBuf.Params.sectionName // instance |
|
Section name for the buffer managed by the instance
var params = new HeapBuf.Params;
...
params.sectionName = String null;
DETAILS
The buffer allocated for a statically created HeapBuf instance will be
placed in this section.
The default section is the 'dataSection' in the platform.
| Static Instance Creation |
|
var params =
new HeapBuf.
Params;
// Allocate instance config-params
params.config = ...
// Assign individual configs
var inst = HeapBuf.create(params);
// Create an instance-object
ARGUMENTS
params
per-instance config params, or NULL to select default values (target-domain only)
eb
active error-handling block, or NULL to select default policy (target-domain only)
DETAILS

Schools are most repsonsible for crimes that occur on their own campuses. How responsible is a school?
Resonsibility likely ranges along with the diversity of challenges facing urban and rural campuses.
Some schools have a promient campus police presence and the majority of students live on campus.
In these situations, schools are very responsible for the crimes that occurs on their campuses, as the crimes are likely
commited by students and the cases investigated by campus police.
Crime rates for urban campuses are likely inflated, as cities experience a higher rate of crime at large.
There is also no certainity that a crime committed on-campus was commited by a student. However, crimes
that occur in on-campus housing facilities are included in the data set.
College enrollments commonly range from a couple hundred students attending liberal arts schools to a
few thousand or more enrolled at large public universities. Schools with larger enrollments should have more crime
simply because they have more students. Standardizing the crime rate accounts for this difference in enrollment
and is a better representation of the probablility of the crime occuring to you.
However, using a standardized rate does have a strong impact on schools with small enrollments located in big cities,
like the Massachusetts General Hospital Dietetic Internship located in Downtown Boston. There are twenty two students enrolled
in the internship. It seems unlikely that four of these students were assulted, equallying a crime rate of 181.8 assults per 1,000 students,
and creating a bubble that is one of the largest on the map. What is more likely is that four assults occurred
on the hospital campus, not involving students, and are largely due to factors inherent to Downtown Boston and hospital settings.

Drake
|
Drake uses a Simulink-inspired description of dynamical systems.
Includes basic building blocks (adders, integrators, delays, etc), physics models of mechanical systems, and a growing list of sensors, actuators, controllers, planners, estimators.
All dynamical systems derive from the drake::systems::System base class, and must explicitly declare all drake::systems::State, drake::systems::Parameters, and noise/disturbances inputs. The drake::systems::Diagram class permits modeling complex systems from libraries of parts.
For a "Hello, World!" example of writing a dynamical system, see simple_continuous_time_system.cc and/or simple_discrete_time_system.cc. For an example of a system that uses some of the more advanced features, such as typed input, output, state, and parameter vectors, see simple_car.h .

Test Requirements(Select Javascript Calculator to test in test suite):
Technology Stack:
1. You can use any mix of HTML, JavaScript, CSS, Bootstrap, SASS, React, Redux, and jQuery to complete this project. You should use a frontend framework (like React for example) because this section is about learning frontend frameworks. Additional technologies not listed above are not recommended and using them is at your own risk. We are looking at supporting other frontend frameworks like Angular and Vue, but they are not currently supported. We will accept and try to fix all issue reports that use the suggested technology stack for this project. Happy coding!
Tests:
- My calculator should contain a clickable element containing an "=" (equal sign) with a corresponding id="equals"
- My calculator should contain 10 clickable elements containing one number each from 0-9, with the following corresponding IDs: id="zero", id="one", id="two", id="three", id="four", id="five", id="six", id="seven", id="eight", and id="nine"
- My calculator should contain 4 clickable elements each containing one of the 4 primary mathematical operators with the following corresponding IDs: id="add", id="subtract", id="multiply", id="divide"
- My calculator should contain a clickable element containing a "." (decimal point) symbol with a corresponding id="decimal"
- My calculator should contain a clickable element with an id="clear"
- My calculator should contain an element to display values with a corresponding id="display"
- At any time, pressing the clear button clears the input and output values, and returns the calculator to its initialized state; 0 should be shown in the element with the id of "display"
- As I input numbers, I should be able to see my input in the element with the id of "display"
- In any order, I should be able to add, subtract, multiply and divide a chain of numbers of any length, and when I hit "=", the correct result should be shown in the element with the id of "display"
- When inputting numbers, my calculator should not allow a number to begin with multiple zeros.
- When the decimal element is clicked, a "." should append to the currently displayed value; two "." in one number should not be accepted
- I should be able to perform any operation (+, -, *, /) on numbers containing decimal points
- If 2 or more operators are entered consecutively, the operation performed should be the last operator entered (excluding the negative (-) sign.
- Pressing an operator immediately following "=" should start a new calculation that operates on the result of the previous evaluation
- My calculator should have several decimal places of precision when it comes to rounding (note that there is no exact standard, but you should be able to handle calculations like "2 / 7" with reasonable precision to at least 4 decimal places)


An LRU cache that stores the signature of a CTP packet instance. An insert operation indicates "use". Inserting an element not in the cache will replace the oldest, and inserting an element already in the cache will refresh its age.

def print_two_again(arg1, arg2):
print "arg1: %r, arg2: %r" % (arg1, arg2)
print_two_again("Steve","Testing")
I have a basic question below to help try get my head around functions in python (following the LPTHW tutorials in prep for uni). Could someone explain the syntax above, and whether I am correct with my assumptions?
I understand that the print_two_again
is the name of the function, but what is the purpose of having the arg1
, arg2
in the parenthesis next to it? Is it to call the "steve" "testing" into the print command below? or do those strings go directing into the print
command?
What is the purpose of having the arg1, arg2 in the parenthesis next to it?
In this case, arg1
and arg2
are called arguments. Arguments allow functions to receive inputs it's expected to use in order to perform a task. The inputs are provided by the callers.
For example, in school math, you may've already seen things like \( z = f(x, y)\) where a function named \(f\) is defined as \(f(x, y) = x + y\). This is the same concept in a programming language.
It also allows you do write more generic, flexible, and reusable code. For example, you don't have to write many different versions of a function to accomplish the same task with slightly different results, avoiding situations like add2(x, y) = x + y
and add3(x, y, z) = x + y + z
, and so on. You can simply do something like:
def sum(values): # values is of type 'list'
result = 0
for value in values:
result += value
return result
#And call it like this:
total = sum([1, 2, 3, 4, 5, 6, 7]) # a list of any length with numbers
#Or like this:
total = sum([1, 2])
How many arguments a function needs will depend on what it needs to do and other factors.
What confuses me is the print_two_again("Steve","testing")
, what is this called and its purpose?
The line print_two_again("Steve","testing")
is an invocation of the function (i.e. a function call). This causes the program to 'jump' into the body of the function named print_two_again
and start executing the code in it.
The ("Steve","testing")
part are the arguments being sent to the function as inputs. These are positional arguments, which basically means that they get "mapped" to the names arg1
and arg2
based on the order in which you've provided them when invoking the function.
For example, consider the function \(f(x, y) = x - y\). If this function is called as \(z = f(3, 4)\) then the argument by the name of x will receive the value 3 and y will be 4, to return -1. If you reverse the arguments in the call, then you'd have \(x=4\) and \(y=3\) and it'd return 1 instead. The same is true of the arguments in the function you've provided.
This means that the order of the arguments in a function call is important.
The Python language, like many others, already has a set of built-in functionality. The function named print is an example of this. You can get a lot of information using the pydoc command (pydoc3 if you use Python3, which I'd recommend). For example, the command pydoc3 print produces the following documentation:
Help on built-in function print in module built-ins:
Note that this is documentation for Python3. Python2 documentation will be slightly different.
There's a direct correlation between your understanding of functions, as seen in your math courses in school, and functions as seen in a programming language. This is because math is part of the underlying foundation of computer science and programming languages, among others (e.g. analysis of algorithms).
Posted by code_dredd on 9/5/15What is the purpose of having the arg1, arg2 in the parenthesis next to it?
arg1 and arg2 are the names of the inputs and from there the function can use those inputs. In your case what your function does is to print them. Other functions can do other things with these arguments. But let's go step by step.
def print_two_again(arg1, arg2):
print "arg1: %r, arg2: %r" % (arg1, arg2)
In the first two lines starting with def, you define a function. It does something. In your case prints the two arguments it takes.
print_two_again("Steve","Testing")
On the third line what you actually do is to call that function. When you call that function you tell the function to pass "Steve" and "Testing" arguments to the function definition.
Above line is literally called a function call. Let's say you have a program and you want it to print two words. You need to define how you want it to be done. This is called function definition, where you define how things work. That's OK, but not enough. You would want to make it happen. So what you do is to execute that function. This is called a function call.
print_two_again("First","Call")
print_two_again("Second","Call")
In the above lines, what we did is to call the previously defined function two times but with different arguments.
Now let's look at the second line, which probably confuses you.
print "arg1: %r, arg2: %r" % (arg1, arg2)
print is a built-in function in Python. What above line does here is to pass arg1 and arg2 arguments and print them with the format of "arg1: %r, arg2: %r"
Posted by Semih Yagcioglu on 9/5/15What is the purpose of having the arg1, arg2 in the parenthesis?
Here def print_two_again(arg1, arg2): is a function and arg1, arg2 is called argument and in function those are two variable and print_two_again function needed two argument.
What confuses me is the print_two_again("Steve","testing")?
When You call print_two_again("Steve","Testing") that, arg1 receive Steve and arg2 receive Testing.
When you want to print, internal (ie. in between ".....") place any text as a simple text and %r use for catch corresponding variable value.
If you want you can rewrite like:
print "Argument 1: %r, Argument 2: %r" % (arg1, arg2)
You can change plane text but variable list follow which name you indicate first.

Configuration Setup¶
Setup is very easy and straight-forward. There are essentially only two configuration points you must concern yourself with:
- Setting the model auto_load directory.
- Configuring your database connections.
By setting the model auto_load directory, you are telling PHP where to look for your model classes. This means that you can have an app/folder structure of your choice as long as you have a real directory that holds your model classes. Each class should have it's own php file that is the same name of the class with a .php extension of course.
There are two ways you can initialize your configuration options. The easiest path is wrapping the calls in a closure which is sent through the Config initializer method. This is a neat and clean way to take advantage of PHP's new closure feature.
1 # inclue the ActiveRecord library
2 require_once 'php-activerecord/ActiveRecord.php';
3
4 ActiveRecord\Config::initialize(function($cfg)
5 {
6 $cfg->set_model_directory('/path/to/your/model_directory');
7 $cfg->set_connections(array('development' =>
8 'mysql://username:password@localhost/database_name'));
9 });
That's it! ActiveRecord takes care of the rest for you. It does not require that you map your table schema to yaml/xml files. It will query the database for this information and cache it so that it does not make multiple calls to the database for a single schema.
If you aren't feeling fancy, you can drop the closure and access the ActiveRecord\Config singleton directly.
1 $cfg = ActiveRecord\Config::instance();
2 $cfg->set_model_directory('/path/to/your/model_directory');
3 $cfg->set_connections(array('development' =>
4 'mysql://username:password@localhost/database_name'));
Default connection
The development connection is the default by convention. You can change this by setting a new default connection based off of one of the connections you passed to set_connections.
1 $connections = array(
2 'development' => 'mysql://username:password@localhost/development',
3 'production' => 'mysql://username:password@localhost/production',
4 'test' => 'mysql://username:password@localhost/test'
5 );
6
7 # must issue a "use" statement in your closure if passing variables
8 ActiveRecord\Config::initialize(function($cfg) use ($connections)
9 {
10 $cfg->set_model_directory('/path/to/your/model_directory');
11 $cfg->set_connections($connections);
12
13 # default connection is now production
14 $cfg->set_default_connection('production');
15 });
Multi-connections
You can easily configure ActiveRecord to accept multiple database connections. All you have to do is specify the connection in the given model that should be using a different database.
1 $connections = array(
2 'development' => 'mysql://username:password@localhost/development',
3 'pgsql' => 'pgsql://username:password@localhost/development',
4 'sqlite' => 'sqlite://my_database.db',
5 'oci' => 'oci://username:passsword@localhost/xe'
6 );
7
8 # must issue a "use" statement in your closure if passing variables
9 ActiveRecord\Config::initialize(function($cfg) use ($connections)
10 {
11 $cfg->set_model_directory('/path/to/your/model_directory');
12 $cfg->set_connections($connections);
13 });
Your models would look like the following.
1 # SomeOciModel.php
2 class SomeOciModel extends ActiveRecord\Model
3 {
4 static $connection = 'oci';
5 }
6
7 # SomeSqliteModel.php
8 class SomeSqliteModel extends ActiveRecord\Model
9 {
10 static $connection = 'sqlite';
11 }
You could also have a base 'connection' model so all sub-classes will inherit the db setting.
1 # OciModels.php
2 abstract class OciModels extends ActiveRecord\Model
3 {
4 static $connection = 'oci';
5 }
6
7 # AnotherOciModel.php
8 class AnotherOciModel extends OciModels
9 {
10 # automatically inherits the oci database
11 }
Setting the encoding
The character encoding can be specified in your connection parameters:
1 $config->set_connections(array(
2 'development' => 'mysql://user:pass@localhost/mydb?charset=utf8')
3 );

The purpose of our research site is to put forth new ideas, theories, speculation and articles that in some way may reflect or connect to the Wicocomico Indian Nation and the Powhatan Empire. At no time will we attempt to analyze the Indians mind 400 hundred years later, we will deal in facts that may lead to an intelligent conclusion or theory. The problem today is that many historians try to reconstruct the Indian's mind set based on the training they received in today's world, this is not the way to build a solid base of past history. The prehistoric Indian's mind set and world view can not possibly be reconstructed by contemporary white people with their mind set and world view.
What is amazing is that more historians do not research contemporary Native American Tribes literature, religion, folk lore, and oral history to make rational conclusions concerning the past. In almost all available information on contemporary Native Americans, they all have many things in common, their close relationship to Mother Earth, fire, water wind, the four directions, the circle, and other symbols of their past. This is their culture that has been passed down from their ancestors. Many of these symbols are discussed in the history written by the Europeans 400-500 years ago, a clear indication that, our contemporary Native American Indians continue to have a different world view than the white race, a strong desire to keep and maintain their heritage.
The articles that we place on our site are in no way implying that the subject matter is part of our history or connected to the Wicocomico Indian Nation in any way, but simply stated, an area of research that runs parallel with our research and subject matter may have covered areas that we previously researched.
The following article is submitted by Wayne Winkler, a well known researcher in the origins of the "Melungeons" a group of people that are older than America. Some of his research and theories include the role and connections the Powhatan's have in Melungeon history.
MULUNGEON ORIGINS
By Wayne Winkler
For more than a century, the Melungeons have been the focus of anthropologists, social scientists, and (especially) feature writers for newspapers and magazines. The most common adjective used to describe the Melungeons is "mysterious;" no one seems to know where the Melungeons originated. More significantly, the Melungeions did not fit into any of the racial categories which define an individual or group within American society, they were considered by their neighbors neither white, black, nor Indian.
The Melungeons are a group of mixed ethnic ancestry, found primarily in northeastern Tennessee, southwestern Virginia, southeastern Kentucky. Similar groups of "mysterious" people, or at least remnants of these groups, are found all along the Atlantic seaboard. While these other groups have no known connection to the Melungeons, they have suffered similar problems due to the difficulty of placing them within an established racial category. Anthropologists called them "racial islands" or "tri-racial isolates."
Several surnames are associated with the Melungeons, including Collins, Gibson, Goins, Mullins, Bowlin. The Melungeons have historically been associated with Newmans Ridge in Hancock County, Tennessee. Newspapers and magazines have found the Melungeons a fascinating topic since the 1840s, but the Melungeons have resented most of the publicity they have received over the years. Most of the articles on the Melungeons speculated on the legends, folklore, and other theories surrounding their ancestry.
Some of these legends and theories have suggested descent from Spanish or Portuguese explorers, from the "Lost Colonists" of Roanoke Island, from the shipwrecked sailors or pirates of various nationalities, from one of the Lost Tribes of Israel, or from ancient Phoenicians or Carthaginians. More recent theories have proposed that the Melungeons descended from Mediterranean or Middle Eastern ancestors.
None of these theories originated with the Melungeons themselves. Early accounts reflect the Melungeons' self description as "Indians." Some Melungeons reportedly described themselves a Portuguese," or, as many pronounced it, Portyghee."Most of their white neighbors considered the Melungeons a mixture of black and Indian or white, black, and Indian.
There is no consistent definition of the word "Melungeon." Some anthropologists have limited the term to a few families located near Newman's Ridge, while others have expanded "Melungeon" to include other mixed-race groups in the southeastern United States. At one time, the word was used as a racial epithet against a mullatto, at another time as a political epithet for east Tennessee Republicans. The common usage of the term had an element of socio-economic status attached to it; families who were financially successful were not necessarily considered Melungeon, no matter who their ancestors were.
By the early 1960s, newspaper articles predicted the disappearance of the Melungeons; out-migration and intermarriage with whites had nearly rendered the Melungeons indistinguishable from their white neighbors. However, by the end of that decade, Melungeons in Hancock County were acknowledging and celebrating their heritage with an outdoor drama. By the mid-1900s, a "virtual community" of Melungeons had developed on the internet.
One question which has been examined by nearly every writer on this subject is the origin of the name "Melungeon." The most commonly accepted theory is that the word derived from the French melange, meaning mixture. A French colony in southwestern Viginia in the late 1700s may have dubbed these people with the plural form of melange, which is melangeon or melangeons, which could conceivably have been corrupted to "Melungeon." Another proposed theory for the origin of "Melungeon" is the Afro-Portuguese term meaning melungo, supposedly meaning shipmate." Yet another is the Greek term melan, meaning "black."
Author Brent Kennedy, in arguing a Trukish origin for the Melungeons, maintains that "Melungeons" derives from the Arabic melun jinnand the Turkishmelun can, both pronounced similarly to " Melungeon" and both translated to "cursed soul" "or one who has been abandoned by God."Kennedy maintains that the Melungeons identified themselves by that name.
Historian C.S.Everett suggests another possible origin for the term melongena, originally an Italian term related to the more modern melanzane (pronounced meh lun zhen eh) which means "eggplant." The eggplant has a dark skin, and the term was used to describe sub-Saharan Africans.
Karlton Douglas and Joanne Pexxullo suggests that the word "Melungeon" originated as the old English term "malengin"(singular) or "malengine"(plural). An old copy of Webster's Dictionary defines "malengine" as "Evil machination; guile;deceit. Douglas and Pessullo write, "It is well known the people of Appalachia, and Melungeons in particular, used words that were becoming archaic, and not much in use beyond Appalachia."
Nearly everyone that has written about the Melungeons agrees that they fiercely resented the name. Even in mid-20th century, to call a Hancock Countian a Melungeon was to insult him. The stigma attached to the name "Melungeon" leads most researchers to the conclusion that the name was imposed upon the people, that it was not a name they ever used for themselves.
Most Melungeons in Hancock County lool very much like their "white" neighbors, many of whom are quite swarthy from a lifetime of outdoor work. In 1963, Brewton Berry wrote,"[N]either in their culture nor their economy are they distinguishable from other mountain folk. Among those bearing the telltale surnames are individuals of dark complexion and straight black hair...But the physical features of most of them suggest no other ancestry than white." Some historic descriptions of Melungeons include:
They are tall, straight, well-formed people, of a dark copper color...but wolly heads and other similar appendages of our negro.
They are swarthy complexion, with prominent cheek bones, jet black hair, generally straight but at times having a slight tendancy to curl, and the men have heavy black beards...Their frames are well built and some of the men are fine specimens of physical manhood. They are seldom fat.
While some of them are swarthy and have high Indian cheekbones, the mountain whites, too, often display these same characteristics. Also, many of the Melungeons have light hair, blue eyes, and fair skin.
The color of the skin of a full-blooded, pure Melungeon is a much richer brown than an Indian's skin. It is not the color of a part Indian and part white, for their skin is lighter. The full-blooded, pure Melungeon had more the color of a skin of a person from India and Egypt.
In 1946, William Gilbert presented the first comprehensive survey of tri-racial groups in the U.S. He estimated that there were at least 50,000 person who were "complex mixtures in varying degrees of white, Indian, and Negro blood."
Gilbert listed ten major tri-racial groups with several related groups. These included:

In light of the ongoing COVID-19 pandemic, Marcus Hansen’s family generously allowed the transcription of his diary to be shared publicly. Marcus’s account of the voyage of the 40th Reinforcements is what follows, beginning with his first entry on July 10, 1918 in Wellington, New Zealand.
conditions onboard a troopship at sea were prime for outbreaks of pandemic influenza.
The worst outbreak experienced by a U.S. troopship happened on the SS Leviathan in early October 1918. By the time the vessel reached its destination, roughly 2,000 of the 11,000 troops and crew (18%), had been infected.
The outbreak on New Zealand transport SS Tahiti, however, saw far worse results. When the Tahiti arrived at Plymouth, U.K., on September 10, 1918, more than 90% of its 1,217 passengers had been or still were infected. Combined with the 7% death rate, what happened on the Tahiti was likely the worst outbreak to occur onboard a troopship during the 1918 pandemic.

Few other firsthand accounts of the tragedy on the Tahiti have surfaced since its ill-fated voyage in the summer of 1918. In 2012, a soldier’s diary was located and transcribed by his grandson, who had discovered it while going through some of his late father’s possessions.
The diarist, private Marcus Christian Hansen, was a member of the 40th Reinforcements, the New Zealand military unit onboard the troopship from July 10 through September 10, 1918. He was 31 years old at the time of the voyage.
Hansen’s diary delivers an unprecedented firsthand account of one the most devastating outbreaks of the 1918 pandemic — an outbreak so severe that the Tahiti became known as the “death ship.”

Browns fans swing football helmet at Mason Rudolph pinata
by Jake TrotterCLEVELAND -- Though Cleveland was set to play the Miami Dolphins on Sunday, Browns fans still had the Pittsburgh Steelers -- and last week's melee -- on the mind.
Cleveland tailgaters even had a Mason Rudolph piñata, and blindfolded fans tried to hit the Steelers quarterback dummy with a Pittsburgh helmet, according to video from Cleveland.com.
Browns defensive end Myles Garrett was suspended for the season for ripping off and swinging Rudolph's helmet into his head in the closing seconds of Cleveland's 21-7 victory Nov. 14. During his appeal with the NFL, Garrett accused Rudolph of inciting him with a racial slur, which Rudolph has denied through his agent.
Thursday night, Garrett stood by his claim in a tweet, which was followed by a statement from general manager John Dorsey, noting Garrett's "unquestionable integrity."
Before Sunday's game with the Dolphins, Browns owner Dee Haslam was photographed with Garrett's No. 95 on her cap in a show of support.
Rudolph's day only got worse as he was benched in the Steelers' game at Cincinnati.
Cleveland travels to Pittsburgh next weekend.

SOFABoot supports modular isolation. But in actual usage scenarios, There is one case that beans in one module sometimes need to open some entries for another module to expand. SOFABoot draws on and uses the Nuxeo Runtime project and the nuxeo project and expands on it, provides the ability to extend points with Spring, We call it Extension Point
.
Usage
Using extension point capabilities in SOFABoot requires the following three steps:
Define a bean that provides extension capabilities
When using the SOFABoot extension point capability, you first need to define an interface that needs to be extended, like:
package com.alipay.sofa.boot.test;
public interface IExtension {
String say();
}
Define the implementation of this interface:
package com.alipay.sofa.boot.test.impl;
public class ExtensionImpl implements IExtension {
private String word;
@Override
public String say() {
return word;
}
public void setWord(String word) {
this.word = word;
}
public void registerExtension(Extension extension) throws Exception {
Object[] contributions = extension.getContributions();
String extensionPoint = extension.getExtensionPoint();
if (contributions == null) {
return;
}
for (Object contribution : contributions) {
if ("word".equals(extensionPoint)) {
setWord(((ExtensionDescriptor) contribution).getValue());
}
}
}
}
Here you can see that there is a method: registerExtension
, you can temporarily ignore this method, and later will introduce its specific role.
In the module’s Spring configuration file, we add configuration of this bean:
<bean id="extension" class="com.alipay.sofa.boot.test.impl.ExtensionImpl">
<property name="word" value="Hello, world"/>
</bean>
Defining extension points
There is a field word in the above bean. In practice, we want this field to be overridden by other module customizations. Here we expose it as an extension point.
First, you need a class to describe this extension point:
@XObject("word")
public class ExtensionDescriptor {
@XNode("value")
private String value;
public String getValue() {
return value;
}
}
Then define the extension point in xml:
<sofa:extension-point name="word" ref="extension">
<sofa:object class="com.alipay.sofa.boot.test.extension.ExtensionDescriptor"/>
</sofa:extension-point>
among them:
- name
is the name of the extension point
- ref
is the bean to which the extension point is applied
- object
is a concrete description of the contribution point of the extension point. This description is done by XMap (XMap is used to map Java objects and XML files. It is recommended to search XMap documents on the Internet to understand XMap)
Defining extension implements
The above has defined the extension point, and we can extend this bean at this point:
<sofa:extension bean="extension" point="word">
<sofa:content>
<word>
<value>newValue</value>
</word>
</sofa:content>
</sofa:extension>
among them:
- bean
is the bean to which the extension is applied
- point
is the name of the extension point
- The content inside content
is an extension definition, which will parse the content through XMap into: the extension point’s contribution point specific description object, here is the com.alipay.sofa.boot.test.extension.ExtensionDescriptor
object
At this point, we can look back at the registerExtension
method defined in com.alipay.sofa.boot.test.impl.ExtensionImpl
. When SOFABoot resolves to the contribution point, it will call the registerExtension of the extended bean. The
method contains the user-defined contribution point processing logic. In the above example, the user-defined value is obtained and set to the value in the word field that overrides the original definition in the bean.
At this point, call the extension
bean’s say()
method, and you can see the value defined in the return extension: newValue.
XMap Support and Extension
The above example is just a very simple extension. In fact, XMap contains a very rich description capability, including List
, Map
, etc. These can be seen by looking at the XMap documentation.
In SOFABoot, in addition to XMap native support, it extends the ability to integrate with Spring:
- Extend XNodeSpring
via XNode
- Extend XNodeListSpring
via XNodeList
- Extend XNodeMapSpring
via XNodeMap
This part of the expansion capabilities, the ability to extend the extension point, the description object can directly point to a SpringBean (user configuration bean name, SOFABoot will get the bean from the spring context according to the name), here is a use of XNodeListSpring
The example is still the three steps described above:
Defining a bean that provides extended capabilities
In this interface definition, we return a list, the goal is that this list can be filled by extension:
package com.alipay.sofa.boot.test;
public interface IExtension {
List<SimpleSpringListBean> getSimpleSpringListBeans();
}
Where SimpleSpringListBean
can be defined according to requirements, here we assume that an empty return is defined.
public class IExtensionImpl implements IExtension {
private List<SimpleSpringListBean> simpleSpringListBeans = new ArrayList<>();
@Override
public List<SimpleSpringListBean> getSimpleSpringListBeans() {
return simpleSpringListBeans;
}
public void registerExtension(Extension extension) throws Exception {
Object[] contributions = extension.getContributions();
String extensionPoint = extension.getExtensionPoint();
if (contributions == null) {
return;
}
for (Object contribution : contributions) {
if ("testSpringList".equals(extensionPoint)) {
simpleSpringListBeans.addAll(((SpringListExtensionDescriptor) contribution)
.getValues());
}
}
}
}
You can see that the bean defined by the extension point is added to the list in registerExtension
to achieve the ability for the user to extend the list.
In the module’s Spring configuration file, we configure this bean:
<bean id="iExtension" class="com.alipay.sofa.runtime.integration.extension.bean.IExtensionImpl"/>
Defining extension points
First, you need an object to describe:
@XObject("testSpringList")
public class SpringListExtensionDescriptor {
@XNodeListSpring(value = "value", componentType = SimpleSpringListBean.class, type = ArrayList.class)
private List<SimpleSpringListBean> values;
public List<SimpleSpringListBean> getValues() {
return values;
}
}
Here we use @XNodeListSpring
. When the name of the corresponding bean is configured in XML, SOFABoot gets the corresponding bean instance from the spring context.
Define this extension point in XML
<sofa:extension-point name="testSpringList" ref="iExtension">
<sofa:object class="com.alipay.sofa.runtime.integration.extension.descriptor.SpringListExtensionDescriptor"/>
</sofa:extension-point>
Defining extensions
<bean id="simpleSpringListBean1" class="com.alipay.sofa.runtime.integration.extension.bean.SimpleSpringListBean" />
<bean id="simpleSpringListBean2" class="com.alipay.sofa.runtime.integration.extension.bean.SimpleSpringListBean" />
<sofa:extension bean="iExtension" point="testSpringList">
<sofa:content>
<testSpringList>
<value>simpleSpringListBean1</value>
<value>simpleSpringListBean2</value>
</testSpringList>
</sofa:content>
</sofa:extension>
When defining an extension, first define two beans and then put them into the extension definition.
At this point, call iExtension.getSimpleSpringListBeans
method, you can see that it contains two beans added by the extension.
Defining extension points and extensions by client mode
In addition to defining extension points and extensions through the above xml configuration, SOFABoot also provides com.alipay.sofa.runtime.api.client.ExtensionClient
to define extension points and extensions.
Get ExtensionClient
Getting com.alipay.sofa.runtime.api.client.ExtensionClient
is relatively simple, and com.alipay.sofa.runtime.api.aware.ExtensionClientAware
is provided in SOFABoot:
public class ExtensionClientBean implements ExtensionClientAware {
private ExtensionClient extensionClient;
@Override
public void setExtensionClient(ExtensionClient extensionClient) {
this.clientFactory = extensionClient;
}
public ExtensionClient getClientFactory() {
return extensionClient;
}
}
Define ExtensionClientBean
as a Spring bean.
定义扩展点
ExtensionPointParam extensionPointParam = new ExtensionPointParam();
extensionPointParam.setName("clientValue");
extensionPointParam.setTargetName("iExtension");
extensionPointParam.setTarget(iExtension);
extensionPointParam.setContributionClass(ClientExtensionDescriptor.class);
extensionClient.publishExtensionPoint(extensionPointParam);
The meaning of each parameter is consistent when the client and the extension point are registered via XML:
among them:
- name
is the name of the extension point
- targetName
is the name of the bean to which the extension point is applied
- target
is the bean to which the extension point is applied
- contributionClass
is a concrete description of the contribution points of the extension point. The definitions described here are as follows:
@XObject("clientValue")
public class ClientExtensionDescriptor {
@XNode("value")
private String value;
public String getValue() {
return value;
}
}
Define extension points by publishExtensionPoint
of com.alipay.sofa.runtime.api.client.ExtensionClient
Defining extension implements
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(new File(Thread.currentThread().getContextClassLoader()
.getResource("META-INF/extension/extension.xml").toURI()));
ExtensionParam extensionParam = new ExtensionParam();
extensionParam.setTargetName("clientValue");
extensionParam.setTargetInstanceName("iExtension");
extensionParam.setElement(doc.getDocumentElement());
extensionClient.publishExtension(extensionParam);
The meaning of each parameter is consistent when the client and the extension point are registered via XML:
- targetInstanceName
is the bean to which the extension is applied
- targetName
is the name of the extension point
- The content inside the element
is an extended definition. Here you need to pass in the Element
object. By reading it from XML, the contents of the example are as follows:
<clientValue>
<value>SOFABoot Extension Client Test</value>
</clientValue>
The extension can be defined by com.alipay.sofa.runtime.api.client.ExtensionClient.publishExtension()

It can be seen that since the definition of the extension is strongly dependent on XML, although the extension point and extension are released through the client, the content of the extension itself needs XML to describe, and does not really use only the client. This part is welcome to contribute.


word HAL_COUNT( dword val);
This macro is provided for use with
HugeArrayLock()
. It extracts the lower word of the
HugeArrayLock()
return value. This is the number of elements in the Huge Array block after the locked one (counting that locked one).
word HAL_PREV( dword val);
This macro is provided for use with
HugeArrayLock()
. It extracts the upper word of the
HugeArrayLock()
return value. This is the number of elements in the Huge Array block before the locked one (counting that locked one).
void HandleModifyOwner( MemHandle mh, /* Handle of block to modify */ GeodeHandle owner); /* Handle of block's new owner */
This routine changes the owner of the indicated global memory block. Note that this routine can be called only by a thread belonging to the block's original owner; that is, you can only use this routine to transfer ownership of a block from yourself to some other geode.
Include: heap.h
Never Use Situations:
Never use this unless the block already belongs to you and you are giving up ownership.

void HandleP( MemHandle mh); /* Handle of block to grab */
If several different threads will be accessing the same global memory block, they need to make sure their activities will not conflict. The way they do that is to use synchronization routines to get control of a block.
HandleP()
is part of one set of synchronization routines.
If the threads are using this family of routines, then whenever a thread needs access to the block in question, it can call
HandleP()
. This routine checks whether any thread has grabbed the block with
HandleP()
(or
MemPLock()
). If no thread has the block, it grabs the block for the calling thread and returns (it does not lock the block on the global heap). If a thread has the block,
HandleP()
puts the thread on a priority queue and sleeps. When the block is free for it to take, it awakens, grabs the block, and returns.When the thread is done with the block, it should release it with
MemUnlockV()
or
HandleV()
.
Include: heap.h
Tips and Tricks: If you will be locking the block after you grab it, use the routine
MemPLock()
(which calls
HandleP()
and then locks the block with
MemLock()
). You can find out if the block is being accessed by looking at the
HM_otherInfo
word (with
MemGetInfo()
). If
HM_otherInfo
equals one, the block is not grabbed; if it equals zero, it is grabbed, but no threads are queued; otherwise, it equals the handle of the first thread queued.
Be Sure To: Make sure that all threads accessing the block use
HandleP()
and/or
MemPLock()
to access the block. The routines use the
HM_otherInfo
field of the handle table entry; do not alter this field. Release the block with
HandleV()
or
MemUnlockV()
when you are done with it.
Warnings: If a thread calls
HandleP()
when it already has control of the block, it will deadlock;
HandleP()
will put the thread to sleep until the thread releases the block, but the thread will not be able to release the block because it's sleeping.
MemThreadGrab()
avoids this conflict. If you try to grab a non-sharable block owned by another thread,
HandleP()
will fatal-error.
