Kogi Election: INEC blunders in result declaration, records higher votes for ruling party
by Damilola OJETUNDETHE total votes recorded for the ruling party, All Progressives Congress, APC, in Kogi State shows that the Incumbent governor, Yahaya Bello has won the Saturday guber election, but the number contradicts the summation of the vote count from each local government area, The ICIR has found.
Final score announced by the Independent National Electoral Commission (INEC) for the APC is 12,682 higher than the actual votes counted. This represents 3.2 per cent surplus in favour of the ruling party.
The Returning Officer and Vice-Chancellor of Ahmadu Bello University, Zaria, Professor Ibrahim Umar, declared at the INEC office in Lokoja that the APC governorship candidate, Yahaya Bello, polled 406,222 votes in total against Musa Wada of the People’s Democratic Party (PDP) who garnered a total 189,704 votes.
Here are the figures as announced by INEC:
| LGA | APC | PDP |
| Adavi | 64,657 | 366 |
| Ajaokuta | 17,952 | 5,565 |
| Ankpa | 11,269 | 28,108 |
| Bassa | 8,386 | 9,724 |
| Dekina | 8,948 | 16,575 |
| Ibaji | 12, 682 | 10,504 |
| Idah | 4,602 | 13,962 |
| Igalamela-Odolu | 8,075 | 11,195 |
| Ijumu | 11,425 | 7,587 |
| Kabba/Bunu | 15,364 | 8,084 |
| Koton Karfe | 14,097 | 9,404 |
| Lokoja | 19,457 | 11,059 |
| Mopa-Muro | 4,953 | 3,581 |
| Ofu | 11,006 | 12,264 |
| Ogori/Magongo | 3,679 | 2,145 |
| Okehi | 36,954 | 478 |
| Okene | 112,764 | 139 |
| Olamaboro | 16,876 | 8,155 |
| Omala | 8,473 | 14,403 |
| Yagba East | 6,735 | 7,546 |
| Yagba West | 7,868 | 8,860 |
| TOTAL | 393,540 | 189,704 |
However, a summation of results from 21 local government areas monitored live by The ICIR shows that the APC candidate instead polled a total 393,540 votes, a difference of 12,682 from the figure announced by the INEC, while the PDP polled 189,704 votes.
The ICIR discovered that 12,682 is also exactly the number of votes that went to the APC candidate at Ibaji Local Government Area, an indication that the result from the area may have been posted twice.
Results from Ibaji were part of the last set of results announced on Monday morning by the electoral commission after it postponed the collation process on Sunday evening.
Rotimi Oyekanmi, Chief Press Secretary to the INEC Chairman, did not deny this finding when The ICIR reached out to him.
“We are going to look at the figure again when the report is sent to the headquarters,” he said.
He also assured The ICIR that the Commission would check for votes other local governments to see if there are double posting of results.


20 DATES A film review by Steve Rhodes Copyright 1999 Steve Rhodes RATING (0 TO ****): ***
Good-looking Myles Berkowitz has two problems that he wants to turn into an opportunity. Facing the failure of his personal life (having been recently divorced) and his professional life as a filmmaker (having never made a movie), he wants to make a documentary of his quest to find love in LA. He proposes to call his first picture 20 DATES because that is precisely how many women he promises to date in the movie.
The movie is actually a mock documentary, but it was realistic enough to fool some of the critics at our press screening. (There are some advantages to films without press kits.) The movie written and directed by and starring Myles Berkowitz, does not have the sharp writing of the wonderfully inventive WAITING FOR GUFFMAN, another mock documentary. Nevertheless, 20 DATES is pure, unadulterated fun, and a perfect date movie. Well, probably not a "first" date movie.
As seems somehow appropriate, 20 DATES uses movie romance as its benchmark for true love. Even if Myles ultimately concludes that "Love, real love, is like a really great movie," along the way he uses delightful clips from classic movies to poke fun at celluloid romance. He argues that real life isn't like the movies, which usually end with the man and the woman running toward each other for the big kiss, while the music comes up. ("Women come and go, but a movie lasts forever, especially if it goes to video," points out one of Myles acquaintances.)
The plot has Myles getting $60,000 from a foul-mouthed financial backer who is never seen. Like some exposť on "60 Minutes," we hear the backer scream obscenities about how he wants the movie done, which Myles rejects for artistic reasons. The backer wants him to use actresses rather than real people and wants Myles and his dates to have sex on camera. While the backer speaks, we see the outside of some sleazy building as his words are shown below it in subtitles.
Myles likes to add cartoonish graphics for humor. As Myles plods through his dates, we see graphics like checkmarks and question marks superimposed on the screen, representing his thinking on how each date is progressing.
The best use of graphics occurs when he pokes fun at the waste of money in most motion pictures. Using stick figures in a bar graph, he likens the money spent on most pictures to the size of the combined United States and Russian armies. In contrast, he says that his film would have had only enough cash to hire a single French soldier who would immediately surrender.
Although handsome and well dressed, except for his proclivity to mix red and green, Myles manages to turn most dates off in subtle ways. While dining out, he complains, for example, about the foods on the menu that would give him diarrhea. Between the dates are interspersed interviews with his friends, who give testament as to how annoying Myles can be.
 We learn that the supermarket is full of them. And if all else fails, borrow a good-looking child and hang out at the beach..
Will Myles finish the entire 20-date course? And will he find love and happiness along the way? These are the key questions in this breezy movie that goes down as easy as the ubiquitous wine that Myles uses with little success to loosen up his prey.
20 DATES runs 1:32. It is rated R for profanity and mature themes and would be fine for teenagers.

Best Android File Manager in 2019
by Jen KarnerBest Android File Manager Android Central 2019
Plenty of us use File Managers to keep track of all of the many files we have. While there are dozens of them available on the Google Play Store, many don't offer the features or ease of access that you want — or need—in a file manager. That being said, the quality of these applications has improved vastly over the years and we have the best you can download today for your Android device.
- Simplicity at its finest: Simple File Manager Pro
- More robust: X-plore File Manager
- The old friend: File Manager by Astro
- Surprisingly good: ASUS File Manager
- A lot of extras: File Manager Pro
- Smarter file management: Files by Google
- All-in-one: MiXplorer Silver File Manager
- Swiss Army Knife-like: Solid Explorer File Manager
Simplicity at its finest: Simple File Manager Pro
Staff Pick
If you don't need all the extra frills that are offered by other apps, then Simple File Manager is perfect for you. The app offers a sleek design, with no ads and additional customization to make the app match your phone's theme.
More robust: X-plore File Manager
In addition to having a throwback theme installed, X-plore File Manager doubles as a media player and even an App Manager. Additionally, you can view thumbnails for your various photos and videos, while also making it easy to access cloud storage options.
Free (with in-app purchases) at Google Play
The old friend: File Manager by Astro
ASTRO File Manager has been one of the best file managers on Google Play for years now and with good reason. It has an easy to use and intuitive UI, which is always a solid plus, but it also comes at the lovely price of free.
Surprisingly good: ASUS File Manager
ASUS File Manager delivers a great experience with all of the features you didn't realize that you wanted. From managing files to storage, its features all work well together, delivering a simple and easy-to-use app.
A lot of extras: File Manager Pro
File Manager Pro is a lightweight and clean file manager app that makes it easy to manage all of your files while supporting cloud storage options. With utilities such as File Sharing and Storage Analysis, this is perfect for keeping all of your files organized.
Smarter file management: Files by Google
Originally, Files by Google was launched as an experiment, but the app's popularity left it as a mainstay for many. The app makes it easier than ever to review your files and with Smart Recommendations, you can get rid of those stale memes for good.
All-in-one: MiXplorer Silver File Manager
MiXplorer is one of those apps that's been around forever, but with MiXplorer Silver, you get a few apps combined into one. The app includes archiving, metadata editing, file tagging, and so much more in a sleek package.
Swiss Army Knife-like: Solid Explorer File Manager
Solid Explorer is similar to a Swiss Army Knife. It does a great job helping you locate and keep those files organized. Plus, there is root access available, making it a great option for those who still root their devices.
Free (with in-app purchases) at Google Play
There are more than enough good options
For years, file manager applications "flooded" the Google Play Store as different developers competed for your admiration. However, as Android has progressed over the years, the built-in file manager can handle just about everything that you need it to. This is especially true with the Files app included with Pixel devices, as it can keep track of files saved directly to your phone, but also files from other apps such as Drive.
Buy one Galaxy S10 or Note 10 and get one free at Verizon
If you don't own a Pixel device, or don't care for the design, we would have to pick Simple File Manager Pro due to its reliable updates and so much more. This file manager is sleek, lightweight, and makes it extremely easy to browse through your file system while including plenty of customization options.
Those looking for more of a robust file manager may want to look at X-plore File Manager with its plethora of methods to keep your files organized. Plus, you get the added benefit of managing your other cloud services such as Google Drive, Dropbox, OneDrive, and others.

are conceptually orthogonal, in practice lambdas are implemented using invokedynamic
.
笔记：lambda是Java Language范围内的概念，而invokedynamic是ClassFile范围内的概念，两者是不相关的（orthogonal）概念。但两者之间也存在联系，即lambda底层的实现是依赖于invokedynamic完成的。
We know that Java code itself does not compile directly to bytes that are executed by the operating system. Instead, the Java compiler (henceforth, “javac”) compiles to another intermediate form, which is executed by the Java Virtual Machine (henceforth, “JVM”). This intermediate form is called the Java bytecode. Bytecode, however, has no concept of lambdas. It also has no concept of try-with-resources blocks, enhanced for-loops, or many of the other structures within Java. Instead, the compiler converts those Java structures into an underlying form in bytecode.
In terms of bytecode, the simplest kind of lambda is the method reference. 笔记：最简单的lambda的表现形式是method reference。
import java.util.function.Supplier; public class HelloWorld { public static String lambdiseMe() { return "Hello World!"; } public static Supplier<String> getSupplier() { return HelloWorld::lambdiseMe; } }
From bytecode perspective, the getSupplier
method is of the same basic form of the lambdiseMe
method:
it executes an opcode to push an object onto the operand stack, and then it returns the object on that operand stack.
The difference is the opcode that pushes the object onto the operand stack.
In lambdiseMe
, it use ldc
to load a constant:
=== === === === === === === === === max_stack = 1 max_locals = 0 code_length = 3 code = 1202B0 === === === === === === === === === 0000: ldc #2 // 1202 || Hello World! 0002: areturn // B0
In getSupplier
, it use invokedynamic
to put the value on the operand stack:
=== === === === === === === === === max_stack = 1 max_locals = 0 code_length = 6 code = BA00030000B0 === === === === === === === === === 0000: invokedynamic #3 // BA00030000 || #0:get:()Ljava/util/function/Supplier; 0005: areturn // B0
The invokedynamic
instruction was introduced in Java 7 to support dynamic languages that ran on the JVM, such as JRuby and Groovy.
These dynamic languages had a similar problem: for certain common method calls, they could not know exactly what method to call until runtime.
笔记：这里指出问题所在，有些方法要在runtime时才能决定。
No amount of polymorphism helped them out笔记：多态，并不能解决这个问题。多态，是同一操作作用于不同的对象，可以有不同的解释，产生不同的执行结果。多态，强调的是“同一个方法”，在不同的对象上调用，有不同的处理方式；而这里的问题是强调“多个方法”，希望能够在多个方法之间进行选择。:
they simply had to defer the decision about what method to run until the moment the code was executed.
The result was that each dynamic language had its own method dispatch structure笔记：不同的语言，在Java已有功能的基础之上，提供了自己的实现，其结果是不利于Java的优化。 built on top of Java's own method dispatch structure, and those structures tended to be bad for Java's optimizations.
To help them out (and lay the groundwork for lambdas), Java 7 introduced invokedynamic
.
笔记：Java 7引入了invokedynamic，一方面为问题提供了解决方法，另一方面也为lambda的出现做了铺垫。
The invokedynamic
instruction tells Java to wait until runtime.
When the invokedynamic
instruction is encountered, it will delegate to another method provided by the classfile, called the “bootstrap method.”
The bootstrap method will be expected to return the method binding for that location, which is encapsulated in the type java.lang.invoke.CallSite
.
That CallSite
has all the information that the JVM needs to execute the target method.
constant_pool ... ... |003| CONSTANT_InvokeDynamic {Value='#0:get:()Ljava/util/function/Supplier;', HexCode='120000001C'}
CONSTANT_InvokeDynamic_info { u1 tag; u2 bootstrap_method_attr_index; u2 name_and_type_index; }
CONSTANT_InvokeDynamic
12tag(18)
00 00bootstrap_method_attr_index(#0)
00 1Cname_and_type_index(#28)
In this case, the instruction executes the Bootstrap Method #0
, which is the “0” argument to the invokedynamic
instruction.
That bootstrap methods have their own pool, and in this case, #0
is the static method metafactory
on the class java.lang.invoke.LambdaMetafactory
.
Every bootstrap method is automatically passed MethodHandles.Lookup
(a utility class to look up methods), the String name of the invoked method, and the type the CallSite
is expected to provide as a MethodType
.
In this case, the type that is expected is a Supplier
, and we are implementing the get
method: that is specified by the other argument to invokedynamic
(the #3
).

In the bootstrap method pool, we see a few other method arguments declared.
These are tacked onto the end, and they are the three remaining arguments to the metafactory
call.
The second argument is the simplest: it is the source of the implementation for the lambda.
In this case, it is the static invocation(invokestatic
) of our lambdiseMe
method.
The first and last arguments are the implementation signature and runtime type of the method being implemented.
The implementation signature is something that takes no arguments and returns an object – ()Ljava/lang/Object;
– because that is the signature of Supplier.get()
that we are trying to match.
However, we also tell the runtime via the third argument that this method will actually always return a String
– ()Ljava/lang/String;
– which is useful for optimization and casting.
笔记：LambdaMetafactory.metafactory()方法，一共接收6个参数，后3个参数由method arguments处获得。
Let's pull it all together. The invokedynamic
instruction is encountered for the first time.
The metafactory
method is called, being passed some default arguments and some custom arguments.
The default arguments are the utility for method lookup, the name of the invoked method, and an instruction to return a Supplier
.
The custom arguments specify that we will implement Supplier.get()
, and even though it normally takes no arguments and returns an Object
,
we will really provide an implementation that takes no arguments and returns a String
.
Another custom argument specifies that the implementation of that is through statically invoking our lambdiseMe
method.
This bootstrap method returns the details about the call site, which is invoked to generate the Supplier
based on our lambda. Whew!
Given all this work for a static method, though, what happens when we want to call a method on some bound object, such as our old friend, System.out::println
?
In the previous section, we saw how a static method was turned into a functional interface implementation via a method reference. The static case is the simplest; binding an instance method is trickier. An instance method also has to store its particular instance for later execution, and that instance has to be used to invoke the method. 笔记：static method可以直接使用“类名”来进行调用，而instance method则需要使用类的实例来进行调用。与static method相比较，instance method很关键的一点就是要“获得类的实例对象”，才能进行调用。
import java.util.function.Consumer; public class HelloWorld { public Consumer<String> getConsumer() { return System.out::println; } }
=== === === === === === === === === max_stack = 2 max_locals = 1 code_length = 14 code = B2000259B6000357BA00040000B0 === === === === === === === === === 0000: getstatic #2 // B20002 || java/lang/System.out:Ljava/io/PrintStream; 0003: dup // 59 0004: invokevirtual #3 // B60003 || java/lang/Object.getClass:()Ljava/lang/Class; 0007: pop // 57 0008: invokedynamic #4 // BA00040000 || #0:accept:(Ljava/io/PrintStream;)Ljava/util/function/Consumer; 0013: areturn // B0 LocalVariableTable: index start_pc length name_and_type 0 0 14 this:Lsample/HelloWorld;
If we compare this to the previous function, we see that there is a bit more going on.
The first thing is the getstatic
call, which loads System.out
onto the operand stack.
Eventually, we will pass that instance into our invokedynamic
call on instruction 8, which will again use the bootstrap method to produce our Consumer
.
The bootstrap method is practically identical to what we saw with the static method reference, except that our method is being invoked using invokevirtual
instead of invokestatic
.
Whereas invokestatic
makes the static method call, invokevirtual
makes an instance method call.
So that is our method reference, and the instance to invoke it on is also passed into the bootstrap method.
BootstrapMethods: 0: #25 invokestatic java/lang/invoke/LambdaMetafactory.metafactory:( Ljava/lang/invoke/MethodHandles$Lookup; Ljava/lang/String; // 本例中，是accept Ljava/lang/invoke/MethodType; // 本例中，是Consumer Ljava/lang/invoke/MethodType; // 本例中，是Consumer.accept()的descriptor Ljava/lang/invoke/MethodHandle; // 本例中，是PrintStream.println()方法 Ljava/lang/invoke/MethodType; // 本例中，是PrintStream.println()方法的descriptor )Ljava/lang/invoke/CallSite; Method arguments: #26 (Ljava/lang/Object;)V #27 invokevirtual java/io/PrintStream.println:(Ljava/lang/String;)V // 注意，这里是invokevirtual #28 (Ljava/lang/String;)V
Aside from that difference, this is all very similar to what we saw before. But what is that stuff in instructions 3, 4, and 7?
0003: dup // 59 0004: invokevirtual #3 // B60003 || java/lang/Object.getClass:()Ljava/lang/Class; 0007: pop // 57
It is possible that this variable came from some other classloader far away, or that it was somehow gamed into existence.
The bootstrap method, however, is going to need access to the class, and is going to need it to be fully formed.
To ensure that the class is fully loaded and accessible in the current context, we will call the Object.getClass()
method on System.out
.
The invokevirtual
call, however, will consume the top element of the stack as the target, and we want to keep the top element around – it's our reference to System.out
.
So we first do a dup
, which duplicates the top element of the stack.
The stack now has two System.out
references, and we consume one with invokevirtual
to call the Object.getClass()
method.
We don't want to actually do anything with the class, however, so we can then just pop
it off the stack.

This class maneuver(巧妙的动作；花招) is the kind of bookkeeping that you do not have to deal with in the world of Java, and which the compiler provides to you free of charge. It also demonstrates the subtlety and complexity of bootstrapping and method handle lookups, which it is very easy to get wrong. So please love and appreciate your compiler! 笔记：这是Java Compiler帮我们做的额外的工作
There is one last kind of method reference: the free instance method reference. This is the case when we pass in a type and an instance method to the method reference, and it creates a method that accepts that type and calls the given instance method. This is somewhat like the bound method reference, in that it has to track what type is being called. However, we do not have a particular instance that is being called in this case, so it can't act like the bound instance method reference. How does it work?
import java.math.BigInteger; import java.util.function.Function; public class HelloWorld { public Function<BigInteger, String> getFunction() { return BigInteger::toString; } }
=== === === === === === === === === max_stack = 1 max_locals = 1 code_length = 6 code = BA00020000B0 === === === === === === === === === 0000: invokedynamic #2 // BA00020000 || #0:apply:()Ljava/util/function/Function; 0005: areturn // B0 LocalVariableTable: index start_pc length name_and_type 0 0 6 this:Lsample/HelloWorld;
It may seem like the free instance method is the strangest of all three types of method references, but the actual implementation is just as simple as the static method reference!
The only difference is that the method handle passed into the bootstrap uses invokevirtual
instead of invokestatic
.
This goes to show that the invokevirtual
and the invokestatic
calls are not directly invoked, but are instead implementation details about the functional interface itself.
So there is no difference between creating a static and a free instance method, except in the way the implementation calls the methods.
BootstrapMethods: 0: #20 invokestatic java/lang/invoke/LambdaMetafactory.metafactory:( Ljava/lang/invoke/MethodHandles$Lookup; Ljava/lang/String; Ljava/lang/invoke/MethodType; Ljava/lang/invoke/MethodType; Ljava/lang/invoke/MethodHandle; Ljava/lang/invoke/MethodType; )Ljava/lang/invoke/CallSite; Method arguments: #21 (Ljava/lang/Object;)Ljava/lang/Object; #22 invokevirtual java/math/BigInteger.toString:()Ljava/lang/String; // 注意，这里是invokevirtual #23 (Ljava/math/BigInteger;)Ljava/lang/String;
The last kind of lambda that you can have is a lambda with an inline definition. We are not talking about a reference to an existing method here, but instead defining an entirely new unit of functionality right inline. You may consider code like this:
import java.util.function.Supplier; public class HelloWorld { public Supplier<String> getSupplier() { return () -> "Hello World!"; } }
$ javap -v -p HelloWorld.class ... ... { ... ... public java.util.function.Supplier<java.lang.String> getSupplier(); descriptor: ()Ljava/util/function/Supplier; flags: ACC_PUBLIC Code: stack=1, locals=1, args_size=1 0: invokedynamic #2, 0 // InvokeDynamic #0:get:()Ljava/util/function/Supplier; 5: areturn LineNumberTable: line 8: 0 LocalVariableTable: Start Length Slot Name Signature 0 6 0 this Lsample/HelloWorld; Signature: #16 // ()Ljava/util/function/Supplier<Ljava/lang/String;>; private static java.lang.String lambda$getSupplier$0(); descriptor: ()Ljava/lang/String; flags: ACC_PRIVATE, ACC_STATIC, ACC_SYNTHETIC Code: stack=1, locals=0, args_size=0 0: ldc #3 // String Hello World! 2: areturn LineNumberTable: line 8: 0 } ... ...  That is called a “synthetic method.” This will be a static method that takes no arguments and returns the string, “Hello, World!”. Once that is created, the compiler has now reduced the problem of the inline lambda into the static method reference problem that we saw before. It is a quite clever solution, and ultimately quite trivial an implementation – which means it is boring for us.
The more interesting case is when you have variables in the mix.
Let's create a method that calls an instance method (requiring access to this
) along with a local variable in the scope.
After all, these lambdas are closures: they enclose their scope. This kind of stuff is their job! How is the compiler going to deal with that complexity? The answer is in Following.
import java.util.function.Supplier; public class HelloWorld { public String provideMessage(String message) { return message; } public Supplier<String> getSupplier(String message) { return () -> this.provideMessage(message); } }
$ javap -v -p HelloWorld.class ... ... { public java.lang.String provideMessage(java.lang.String); descriptor: (Ljava/lang/String;)Ljava/lang/String; flags: ACC_PUBLIC Code: stack=1, locals=2, args_size=2 0: aload_1 1: areturn LineNumberTable: line 8: 0 LocalVariableTable: Start Length Slot Name Signature 0 2 0 this Lsample/HelloWorld; 0 2 1 message Ljava/lang/String; MethodParameters: Name Flags message public java.util.function.Supplier<java.lang.String> getSupplier(java.lang.String); descriptor: (Ljava/lang/String;)Ljava/util/function/Supplier; flags: ACC_PUBLIC Code: stack=2, locals=2, args_size=2 0: aload_0 1: aload_1 2: invokedynamic #2, 0 // InvokeDynamic #0:get:(Lsample/HelloWorld;Ljava/lang/String;)Ljava/util/function/Supplier; 7: areturn LineNumberTable: line 12: 0 LocalVariableTable: Start Length Slot Name Signature 0 8 0 this Lsample/HelloWorld; 0 8 1 message Ljava/lang/String; MethodParameters: Name Flags message Signature: #21 // (Ljava/lang/String;)Ljava/util/function/Supplier<Ljava/lang/String;>; private java.lang.String lambda$getSupplier$0(java.lang.String); descriptor: (Ljava/lang/String;)Ljava/lang/String; flags: ACC_PRIVATE, ACC_SYNTHETIC Code: stack=2, locals=2, args_size=2 0: aload_0 1: aload_1 2: invokevirtual #3 // Method provideMessage:(Ljava/lang/String;)Ljava/lang/String; 5: areturn LineNumberTable: line 12: 0 LocalVariableTable: Start Length Slot Name Signature 0 6 0 this Lsample/HelloWorld; 0 6 1 message Ljava/lang/String; MethodParameters: Name Flags message final synthetic } ... ... BootstrapMethods: 0: #27 invokestatic java/lang/invoke/LambdaMetafactory.metafactory:( Ljava/lang/invoke/MethodHandles$Lookup; Ljava/lang/String; Ljava/lang/invoke/MethodType; Ljava/lang/invoke/MethodType; Ljava/lang/invoke/MethodHandle; Ljava/lang/invoke/MethodType; )Ljava/lang/invoke/CallSite; Method arguments: #28 ()Ljava/lang/Object; #29 invokespecial sample/HelloWorld.lambda$getSupplier$0:(Ljava/lang/String;)Ljava/lang/String; // 注意，这里是invokespecial #30 ()Ljava/lang/String;
Now things have gotten really quite strange. We see the example of the synthetic method with the strange name: lambda$getSupplier$0(java.lang.String);
.
That is an instance method that takes a String
, and calls provideMessage
on that string using the instance: it loads aload_0
, which is this
, and then aload_1
, which is the argument, and then does an invokevirtual
.
Our getSupplier
method does something similar: it loads the this
and message
, and then does our familiar invokedynamic
call to generate the Supplier
.
Note that we are passing in two arguments to invokedynamic
now:
all the variables that we need to reference inside our lambda implementation become arguments to invokedynamic
.
This is called “lambda lifting”: we lift the bound variables out of the lambda and make them arguments to instantiating it.
The signal that we have performed lambda lifting is the use of invokespecial
as our means of method invocation:
we saw it used before to signal a constructor, but now we are using it as a signal to the bootstrap method that we are having to construct a new instance with the lifted arguments.
The important part to realize is that declaring a lambda that uses variables is a lot like declaring a new type that refers to those variables: we will end up instantiating a new instance that will hold onto those variables, and it will end up referring to those member fields when it executes. Therefore, defining a lambda inline and defining your own anonymous inner class have practically identical performance characteristics. Use whichever approach is more natural for the space you are in. 笔记：在使用局部变量的情况下，定义lambda和定义inner class是相类似的。

Automatic command line parsing
No need to manually parse command line options for your scripts, bds
does it for you.
bds
automatically parse any command line line argument that starts with "-" and assigns the value to the corresponding variable global variable (if the variable exists).
Example (test_20.bds):
#!/usr/bin/env bds
in := "in.txt"
print("In file is '$in'\n")
If we run this, we get
$ ./test_20.bds
In file is 'in.txt'
Now we pass a command line argument -in another_file.txt
, and bds
automatically parses that command line option replacing the value of variable in
$ ./test_20.bds -in another_file.txt
In file is 'another_file.txt'
This feature also works for other data types (int
, real
, bool
or lists).
Flags
In case of bool
if the option is present, the variable is set to true
.
File test_21.bds
#!/usr/bin/env bds
bool flag
print("Variable flag is $flag\n")
$ ./test_21.bds
Variable flag is false
$ ./test_21.bds -flag
Variable flag is true
Or you can specify the value (true
or false
which is useful to set to false
a bool that is by default true
:
File test_21b.bds
#!/usr/bin/env bds
flagOn := true
flagOff := false
print("flagOn = $flagOn\nflagOff = $flagOff\n")
So in this example we can reverse the defaults by running this (note that we can use -flagOff
instead of -flagOff true
):
$ ./test_21b.bds -flagOn false -flagOff true
flagOn = false
flagOff = true
Note that we can use -flagOff
instead of -flagOff true
.
Lists
You can also apply this to a list of strings.
In this case, all command line arguments following the -listName
will be included in the list (up to the next argument starting with '-').
E.g.: Note that list in
is populated using in1.txt in2.txt in3.txt
and out
is set to zzz.txt
File test_22.bds
#!/usr/bin/env bds
in := ["in.txt"]
out := "out.txt"
ok := false
print("In : $in\n")
print("Out: $out\n")
print("OK : $ok\n")
$ ./test_22.bds -ok -in in1.txt in2.txt in3.txt -out zzz.txt
In : [in1.txt, in2.txt, in3.txt]
Out: zzz.txt
OK : true

Manage messages.
All message-related operations require that Client-ID be included in the headers. This is to ensure that messages are not echoed back to the client that posted them unless the client explicitly requests this.
Posts the message or messages for the specified queue.
This operation posts the specified message or messages.
You can submit up to 10 messages in a single request, but you must always encapsulate the messages in a collection container (an array in JSON, even for a single message - without the JSON array, you receive the "Invalid request body" message). The resulting value of the Location header or response body might be used to retrieve the created messages for further processing.
The client specifies only the body and TTL for the message. The server inserts metadata, such as ID and age.
The response body contains a list of resource paths that correspond to each message submitted in the request, in the order
of the messages. If a server-side error occurs during the processing of the submitted messages, a partial list is returned,
the partial attribute is set to true, and the client tries to post the remaining messages again. If the server cannot enqueue
any messages, the server returns a 503 Service Unavailable
error message.
The body
attribute specifies an arbitrary document that constitutes the body of the message being sent.
The following rules apply for the maximum size:
The maximum size of posted messages is the maximum size of the entire request document (rather than the sum of the individual message body field values as it was in earlier releases). On error, the client will now be notified of how much it exceeded the limit.
The size is limited to 256 KB, including whitespace.
The document must be valid JSON. (Cloud Queues validates it.)
The ttl
attribute specifies how long the server waits before marking the message as expired and removing it from the queue. The value
of ttl
must be between 60 and 1209600 seconds (14 days). Note that the server might not actually delete the message until its age
has reached up to (ttl + 60) seconds, to allow for flexibility in storage implementations.

Gets the message or messages in the specified queue.
A request to list messages when the queue is not found or when messages are not found returns 204, instead of 200, because there was no information to send back. Messages with malformed IDs or messages that are not found by ID are ignored.
This operation gets the message or messages in the specified queue.
Message IDs and markers are opaque strings. Clients should make no assumptions about their format or length. Furthermore, clients should assume that there is no relationship between markers and message IDs (that is, one cannot be derived from the other). This allows for a wide variety of storage driver implementations.
Results are ordered by age, oldest message first.
| Parameter | Style | Type | Description |
|---|---|---|---|
| marker (Optional) | query | xsd:string |
Specifies an opaque string that the client can use to request the next batch of messages. The marker parameter communicates to the server which messages the client has already received. If you do not specify a value, the
API returns all messages at the head of the queue (up to the limit).
|
| limit (Optional) | query | xsd:integer | When more messages are available than can be returned in a single request, the client can pick up the next batch of messages by simply using the URI template parameters returned from the previous call in the "next" field. Specifies up to 10 messages (the default value) to return. If you do not specify a value for the limit parameter, the default value of 10 is used. |
| echo (Optional) | query | xsd:boolean |
Determines whether the API returns a client's own messages. The echo parameter is a Boolean value (true or false ) that determines whether the API returns a client's own messages, as determined by the uuid portion of the User-Agent header. If you do not specify a value, echo uses the default value of false . If you are experimenting with the API, you might want to set echo=true in order to see the messages that you posted.
|
| include_claimed (Optional) | query | xsd:boolean |
Determines whether the API returns claimed messages and unclaimed messages. The include_claimed parameter is a Boolean value (true or false ) that determines whether the API returns claimed messages and unclaimed messages. If you do not specify a value, include_claimed uses the default value of false (only unclaimed messages are returned).

Gets a specified set of messages from the specified queue.
This operation provides a more efficient way to query multiple messages compared to using a series of individual
Unlike the Get Messages operation, a client's own messages are always returned in this operation. If you use the ids parameter, the echo parameter is not used and is ignored if it is specified.
The message attributes are defined as follows:
href
is an opaque relative URI that the client can use to uniquely identify a message resource and interact with it.
ttl
is the TTL that was set on the message when it was posted. The message expires after (ttl - age) seconds.
age
is the number of seconds relative to the server's clock.
body
is the arbitrary document that was submitted with the original request to post the message.
| Parameter | Style | Type | Description |
|---|---|---|---|
| ids (Optional) | query | xsd:string | Specifies the IDs of the messages to get. Format multiple message ID values by separating them with commas (comma-separated). |

Deletes the specified message from the specified queue.
This operation immediately deletes the specified message.
The claim_id
parameter specifies that the message is deleted only if it has the specified claim ID and that claim has not expired. This
specification is useful for ensuring only one worker processes any given message. When a worker's claim expires before it
can delete a message that it has processed, the worker must roll back any actions it took based on that message because another
worker can now claim and process the same message.
If you do not specify claim_id
, but the message is claimed, the operation fails. You can only delete claimed messages by providing an appropriate claim_id
.
| Parameter | Style | Type | Description |
|---|---|---|---|
| claim_id (Optional) | query | xsd:string | Identifies the claim. |

HTTP/1.1 204 No Content
Perform claim operations.
Claims a set of messages from the specified queue.
This operation claims a set of messages (up to the value of the limit
parameter) from oldest to newest and skips any messages that are already claimed. If no unclaimed messages are available,
the API returns a 204 No Content
message.
When a client (worker) finishes processing a message, it should delete the message before the claim expires to ensure that the message is processed only once. As part of the delete operation, workers should specify the claim ID (which is best done by simply using the provided href). If workers perform these actions, then if a claim simply expires, the server can return an error and notify the worker of the race condition. This action gives the worker a chance to roll back its own processing of the given message because another worker can claim the message and process it.
The age given for a claim is relative to the server's clock. The claim's age is useful for determining how quickly messages are getting processed and whether a given message's claim is about to expire.
When a claim expires, it is released. If the original worker failed to process the message, another client worker can then claim the message.
Note that claim creation is best-effort, meaning the worker may claim and return less than the requested number of messages.
The ttl
attribute specifies how long the server waits before releasing the claim. The ttl value must be between 60 and 43200 seconds
(12 hours). You must include a value for this attribute in your request.
The grace
attribute specifies the message grace period in seconds. The value of grace
value must be between 60 and 43200 seconds (12 hours). You must include a value for thia attribute in your request. To deal
with workers that have stopped responding (for up to 1209600 seconds or 14 days, including claim lifetime), the server extends
the lifetime of claimed messages to be at least as long as the lifetime of the claim itself, plus the specified grace period.
If a claimed message would normally live longer than the grace period, its expiration is not adjusted.
| Parameter | Style | Type | Description |
|---|---|---|---|
| limit (Optional) | query | xsd:integer |
Specifies the number of messages to return, up to 20 messages. If limit is not specified, limit defaults to 10.

Subhas Chandra Bose said that: "Bhagat Singh had become the symbol of the new awakening among the youths." Nehru acknowledged that Bhagat Singh's popularity was leading to a new national awakening, saying: "He was a clean fighter who faced his enemy in the open field ... he was like a spark that became a flame in a short time and spread from one end of the country to the other dispelling the prevailing darkness everywhere". Four years after Singh's hanging, the Director of the Intelligence Bureau, Sir Horace Williamson, wrote: "His photograph was on sale in every city and township and for a time rivaled in popularity even that of Mr. Gandhi himself".

yield - yields CPU to other coroutines
#include <libdill.h>
int yield(void);
By calling this function, you give other coroutines a chance to run.
You should consider using yield when doing lengthy computations which don't have natural coroutine switching points such as socket or channel operations or msleep.
In case of success the function returns 0. In case of error it returns -1 and sets errno to one of the values below.
for(i = 0; i != 1000000; ++i) {
expensive_computation();
yield(); /* Give other coroutines a chance to run. */
}

In Flanders fields the poppies blow
Between the crosses, row on row,
That mark our place; and in the sky
The larks, still bravely singing, fly
Scarce heard amid the guns below.
