Dub changes
List of all bug fixes and enhancements in D 2.085.0.
Compiler changes
- Add support for Objective-C classes
Prior to this release D interfaces were used to represent Objective-C classes. Now proper support for Objective-C classes has been added and D classes can be used instead to represent Objective-C classes. It's preferred to use D classes to represent Objective-C classes.
This release also adds support for implementing Objective-C subclasses and methods in D.
To match the behavior in Objective-C some additional changes have been made:
- static and final methods are virtual. Although final methods are virtual it's not possible to override a final method in a subclass
- static methods are overridable in subclasses
Example:
extern (Objective-C) class NSObject { static NSObject alloc() @selector("alloc"); NSObject init() @selector("init"); void release() @selector("release"); } extern (Objective-C) class Foo : NSObject { override static Foo alloc() @selector("alloc"); override Foo init() @selector("init"); int bar(int a) @selector("bar:") { return a; } } void main() { auto foo = Foo.alloc.init; scope (exit) foo.release(); assert(foo.bar(3) == 3); }
- Add support for Objective-C instance variable
It's now possible to declare instance variables in Objective-C classes.
Instance variables in Objective-C are non-fragile. That means that the base class can change (add or remove instance variables) without the subclasses needing to recompile or relink. Thanks to this feature it's not necessary to declare instance variables when creating bindings to Objective-C classes.
Example:
extern (Objective-C) class NSObject {} extern (Objective-C) class Foo : NSObject { int bar; static Foo alloc() @selector("alloc"); Foo init() @selector("init"); void release() @selector("release"); void getBar() @selector("getBar") { return bar; } } void main() { auto foo = Foo.alloc.init; scope (exit) foo.release(); foo.bar = 3; assert(foo.getBar() == 3); }
- Add support for Objective-C super calls
It's now possible to implement an Objective-C method and make a super call to a method in the base class.
Example:
extern (Objective-C) class NSObject { void release() @selector("release"); } extern (Objective-C) class Foo : NSObject { int foo() @selector("foo") { return 3; } } extern (Objective-C) class Bar : Foo { static Bar alloc() @selector("alloc"); Bar init() @selector("init"); override int foo() @selector("foo") { return super.foo() + 1; } } void main() { auto bar = Bar.alloc.init; scope (exit) bar.release(); assert(bar.foo() == 4); }
- Deprecate Objective-C interfaces
Prior to this release, it was necessary to represent an Objective-C class as a D interface. Now support for Objective-C classes has been implemented and the class keyword should be used instead.
The reason for this deprecation is to allow extern (Objective-C) interfaces to be repurposed for representing Objective-C protocols in the future.
Deprecated:
extern (Objective-C) interface NSObject {} // deprecated
Replace with:
extern (Objective-C) class NSObject {}
- Context-aware assertion error messages
With this release DMD supports generating context-aware assertion error messages when no error message has been provided by the user. For example, currently the following file:
void main() { int a, b = 2; assert(a == b); }
would yield this error when compiled and run:
> dmd -run main.d core.exception.AssertError@main.d(4): Assertion failure –––––––––– ??:? _d_assertp [0x1c4eae48] onlineapp.d:4 _Dmain [0x1c4ead85]
However, with the new experimental compiler switch -checkaction=context it yields:
> dmd -checkaction=context -run main.d core.exception.AssertError@main.d(4): 0 != 2 –––––––––– ??:? _d_assert_msg [0x4a3f9cf0] ??:? _Dmain [0x4a3f8fc4]
The new switch already supports a variety of assertion messages:
string dlang = "d2"; assert(dlang != dlang); // ERROR: "d2" == "d2" struct S { int s; } assert(S(0) == S(1)); // ERROR: "S(0) !is S(1)" int a = 1, b = 2; assert(a > b); // ERROR: 1 <= 2
Also if no error message can be generated, it will now fallback to displaying the text of the assert expression. For example, for this more complicated assert expression:
void main() { int a, b = 2; assert(a && (a == b)); }
Compiling and running with -checkaction=context will now result in:
> dmd -checkaction=context -run main.d core.exception.AssertError@main.d(4): assert(a && (a == b)) failed –––––––––– ??:? _d_assert_msg [0xb7e5fdfc] ??:? _Dmain [0xb7e5fd40]
This switch for context-aware assertion error messages is still experimental and feedback is welcome.
- Avoid calling the struct constructor from const-casts
In previous versions of DMD, there was an undocumented interaction of const-cast with regular cast, ie. cast(), cast(const) and cast(immutable), where these casts would be expressed as cast(const(typeof(expr))) expr; hence if expr was of type Struct, these casts could potentially call its constructor Struct(expr), as per spec.
The dangerous part however, was if this occurred with structs that used their first field as alias this, the implicit conversion via alias this would potentially satisfy an implicit struct constructor, leaving the other fields set to init and leading to apparent data corruption from a mere cast().
In other words, cast() s to S(s) to S(s.implicitCast).
This can no longer occur, since cast(), cast(const) and cast(immutable) will no longer generate an implicit constructor call. Implicit constructor calls to S() will only occur when one explicitly uses cast(S).
- dmd now supports expressive diagnostic error messages with -verrors=context
With the new CLI option -verrors=context dmd will now show the offending line directly in its error messages. Consider this faulty program test.d:
void foo() { a = 1; }
Now run it with -verrors=context:
> dmd -verrors=context test.d test.d(4): Error: undefined identifier a a = 1; ^
- memcmp() compares are no longer performed for struct equality tests, memberwise comparisons are done instead, per the spec
The compiler would sometimes generate code for struct equality tests using memcmp() across the whole struct object. This assumed that:
- alignment holes were filled with 0, which is not always the case
- there were no floating point NaN values, which should compare as not equal even if the bit patterns match
The spec requires that the comparison be done in a memberwise manner. This brings the implementation in line with this.
This can break existing code that relied on the former erroneous behavior. To correct such code, use one of the following:
- define an opEquals() operator overload to achieve the desired behavior
- use is instead of ==, as is will do a bit compare of the struct object.
This new behavior is enabled with the -preview=fieldwise compiler switch. It will eventually become the default behavior.
- OSX 32-bit is no longer supported
With this release, the DMD compiler will no longer officially support building 32-bit applications for OSX. For legacy purposes, older releases can be used.
Motivation: The latest macOS release Mojave is the last version of OSX with support for running 32-bit applications. The D development team wants to focus its efforts and build/test infrastructure on active and important platforms.
- -preview and -revert command line switches have been introduced
Command line switches adding or subtracting features of the D language have been normally added on an ad-hoc basis. Over time this has grown to:
- -dip25
- -dip1000
- -dip1000
- -dip1008
Moreover, in parallel -transition has been introduced and the following DMD example is only a subset of the transitional features that DMD supports at the moment:
dmd -transition=3449 -transition=10378 -transition=14246 -transition=14888 -transition=16997
While these transitions also have a name alias, it's still not clear for the user whether the transition is (a) an experimental feature or an upcoming breaking change, (b) a warning or help on an upcoming change, or (c) revert of a change for users who don't want to deal with the breaking change for now.
With this release, DMD gained a -preview command line switch which can be used to test upcoming features or potentially breaking changes. For example, with this release the list of upcoming features is:
- -preview=dip25: Implements DIP25 (Sealed references)
- -preview=dip1000: Implements DIP1000 (Scoped Pointers)
- -preview=dip1008: Implements DIP1008 (@nogc Throwables)
- -preview=markdown: Enables Markdown replacements in Ddoc
- -preview=fixAliasThis: Enables a potentially breaking fix for alias this with which DMD will first check the this scope before searching in upper scopes
- -preview=intpromote: Enables integral promotion for the unary +, - and ~ operators
- -preview=dtorfields: Enables a potentially breaking fix which enables to destruct fields of partially constructed objects
Adding new features can be disruptive to existing code bases. By initially putting them behind a -preview switch users will have ample opportunity to adapt to them at their own pace.
Therefore, for end users the new -preview interface allows a glimpse into the future. As always, feedback and bug reports for all -preview features is very welcome and encouraged, so that potential problems or breakages can be caught early.
Whenever a -preview feature gets enabled by default, it must pass on all Continuous Integrations, pass the test suite of about 50 of the most popular D packages and be without any other known major real-world issues on Bugzilla.
However, as the behavior of DMD could still deviate slightly from previous versions, sometimes a -revert switch might be introduced by the D development team which allows an easy opt-out of a new feature for users in case they run into issues. As of now, DMD offers these reverts:
- -revert=dip25: Reverts DIP25 changes
- -revert=import: Revert to single phase name lookup
Transitioning to new features (or fixing an important bug) is very often not trivial which is why an additional -transition exists. The -transition options are informational only and intended to help gauge the problems of an upcoming change or assist debugging these changes. For example, DMD currently supports these transitions:
- -transition=field: List all non-mutable fields which occupy an object instance
- -transition=checkimports: Emit deprecation messages about 10378 anomalies
- -transition=complex: Emit deprecation messages for all usages of complex or imaginary types
- -transition=tls: List all variables going into the thread local storage
- -transition=vmarkdown: List instances of Markdown replacements in Ddoc
-transition command line switches might be turned into actual deprecations if the importance of a change is considered high enough (compared to the impact on real-world code), but they are only intended as information for developers on where they would be affected by a certain transition.
As all of this information will be updated continuously with each release, all three command line switches support a help page with either h, help or ? option listing all currently available options:
> dmd -preview=help ... > dmd -revert=help ... > dmd -transition=help ...
IMPORTANT: All old command line switches will continue to work and won't be deprecated. However, they were removed from the documentation and new code is encouraged to use -preview or -revert where applicable.
- Transition to C++11 character types
With C++11 comes the advent of changed character type mangling. D's default behavior will be to conform to this after a one release transition period. A new switch -extern-std={c++98,c++11} is added to control the version that compatibility is set to. This switch sets __traits(getTargetInfo, "cppStd") to the value of __cplusplus that the corresponding version of the C++ standard defines.
Of particular note is the new difference between wchar and wchar_t on Windows. This will manifest itself as compile errors when interfacing wchar* with wchar_t* code when calling the Windows API. A cast will resolve the issue.
Going forward we recommend using WCHAR instead of wchar or wchar_t when interfacing to Windows API functions. (WCHAR is Microsoft Windows' 16 bit character type.)
C++ Type Equivalence
c++98 behavior:
D Posix DMC++ Windows VC++ Windows wchar unsigned short wchar_t wchar_t dchar wchar_t unsigned unsigned wchar_t wchar_t wchar_t wchar_t WCHAR -- wchar_t wchar_t c++11:

Runtime changes
- Added GC.profileStats() to core.memory
Allows access to current GC profiling information. See core.memory.GC.ProfileStats for a list of profile stats.
- Added core.stdcpp.new_
Added core.stdcpp.new_, which exposes interfaces for C++ global new/delete operators. This allows D programs to conveniently allocate from the C++ heap, which is useful when sharing memory between languages.
- Added core.sys.linux.sched.CPU_COUNT.
Added core.sys.linux.sched.CPU_COUNT, which returns the number of CPUs in set.
- Added core.sys.linux.sched.CPU_ISSET.
Added core.sys.linux.sched.CPU_ISSET, which tests to see if cpu is a member of set.
- Moved std.conv.emplace, std.algorithm.mutation.move, std.algorithm.mutation.moveEmplace, and std.functional.forward to core/lifetime.d
emplace is the counterpart to destroy, so it has been moved to also live in druntime (core/lifetime.d) where it is accessible by projects that use a shallow runtime library stack. move, moveEmplace, and forward are related low-level construction machinery which also belong in core.lifetime.
- GC cleanup can now be configured as a DRT GC option
The default cleanup method for the GC is to unconditionally run a collection before runtime termination to finalize objects that are still alive and hold resources that affect system state outside the current process. This combines the worst of possible alternatives: it can cause a considerable delay and does not guarantee finalization of all objects as roots might still exist.
The cleanup behaviour can now be configured by a DRT option to the GC configuration, e.g. by passing --DRT-gcopt=cleanup:none on the command line. Three options are provided:
- collect: run a collection (the default for backward compatibility)
- none: do nothing
- finalize: all live objects are finalized unconditionally
As usual, you can also embed the configuration into the application by redefining rt_options, e.g.
extern(C) __gshared string[] rt_options = [ "gcopt=cleanup:none" ];
- A garbage collector with precise heap scanning can now be selected
Precise heap scanning can now be enabled by a DRT option to the GC configuration, e.g. by passing --DRT-gcopt=gc:precise on the command line or by redefining rt_options. See the documentation for details.
- GC.realloc is now more consistent and robust
The specification of core.memory.GC.realloc has changed slightly:
- GC.realloc now returns null for failure. (It used to return the original pointer but that is is not a good indication of failure as it might also be returned on success. It can lead to overwriting memory if an enlargement was requested.)
- as with GC.free, the caller has to ensure that there are no other live pointers to the memory passed to GC.realloc (This used to be required only when passing a new size 0).
- as a consequence the GC is allowed to free the memory immediately (the previous implementation did this for objects larger than 4kB when shrinking).
- block attribute bits on the existing block are only set if it is reused (the previous implementation didn't set bits if it reused a small block).
The implementation now properly verifies that pointers are actually base pointers to allocated GC memory (passing other pointers could have crashed immediately or corrupt the GC).
- User supplied garbage collectors can now be linked with the runtime
A GC registry has been implemented that allows to add garbage collector implementations by just linking them into the binary. See the documentation for details.
- Added core.stdcpp.allocator
Added core.stdcpp.allocator, which exposes the C++ std::allocator<T> class. This is a required foundation for any of the allocating STL container types.
- char/wchar fields in most D runtime (core.* and rt.*) structs are now zero-initialized
Fields that are single char/wchar or fixed-length arrays of such are now initialized to all zero bits instead of all one bits for most structs in the D runtime (core.* and rt.* modules). This simplifies initialization and removes the need to store init data when it makes the entire struct zero-initialized. Most affected structs are used for interoperability with C APIs.
Dub changes
- dub fetch now supports <package>@<version> as a shortcut
dub fetch <package>@<version> is a shortcut for dub fetch <package> --version=<version>:
> dub fetch<EMAIL_ADDRESS>Fetching gitcompatibledubpackage 1.0.4...
- extraDependencyFiles attribute added
Using attribute extraDependencyFiles a list of files can be specified causing rebuild on change.
- File system supplier enabled
Existing file system supplier is enabled for usage. It searches a certain directory for files with names of the form "[package name]-[version].zip".
Example dub fetch mypackage --registry=file:///etc/dub/packages/
- toolchainRequirements recipe entry
DUB now supports a new entry in dub.json or dub.sdl to restrict the versions of DUB and of compilers supported by a package.
dub.json:
{ "toolchainRequirements": { "dub": "~>1.10", "frontend": ">=2.068 <2.083" } }
dub.sdl:
toolchainRequirements dub="~>1.10" frontend=">=2.068|<2.083"
Supported entries in toolchainRequirements are:
- dub
- frontend
- dmd
- ldc
- gdc
Each can contain a version specification, where DMD-like versions are supported in addition to SemVer versions. For compilers, instead of a version specification, the keyword no can also be used to indicate that the compiler should not be used for this package.
Example scenario:
Package that needs DUB>=1.12, and that will only build with LDC>=1.10:dub.json:
{ "toolchainRequirements": { "dub": ">=1.12", "dmd": "no", "gdc": "no", "ldc": ">=1.10" } }
dub.sdl:
toolchainRequirements dub=">=1.12" dmd="no" gdc="no" ldc=">=1.10"

Write a Passthrough Service
Now that you have written a main program for an integration scenario, it is time to work with services.
This tutorial provides instructions on how to write a REST service that uses the Google Books API to get books about a given topic. This scenario is demonstrated by querying books on WSO2.
This tutorial consists of the following main sections.
- About service URLs
- Add a service
- Add integration logic to your service
- View the Swagger definition for your service
- Add a client connector
- Call the client connector
- Extract content from the JSON
Prerequisites: Download Ballerina and set it up. For instructions on how to do this, see the Quick Tour. it is also recommended to try to write a main program as some concepts are explored in detail in that tutorial. It may also be useful to read and understand the section about service URLs.
When defining a Ballerina program as a service instead of an executable program, the service
construct acts as the top-level container that holds all the integration logic and can interact with the rest of the world. Its base path is the context part of the URL that clients use when sending requests to the service. You create one service per Ballerina program file.
A service is a container of resources
, each of which defines the logic for handling one type of request. Services are singletons, so all variables defined within a service scope are shared across all resource invocations. A service can have state for as long as it's active.
About service URLs
In this tutorial, the service and the resource are also represented by the URL that you are calling. For example, the basepath for a resource can be as follows:
http://localhost:9090/
The following is the URL for the books
service:
http://localhost:9090/books
If you are accessing a different service, like magazines
for example, you can have magazines instead of books in the above URL.
If you are accessing a resource within this service, like book titles for example, the URL is as follows:
http://localhost:9090/books/title
This is how resources and services can equate to the URL that you are calling.
In addition to this, there can be a query parameter added to the title. In this scenario, you are querying books that have "WSO2" in the title, so the URL is as follows.
http://localhost:9090/books/title?title=wso2
Add a service
To get started, add a service in the Ballerina Composer.
-
To define a service in the Composer, drag the service from the tool palette to the canvas. You can then set the base path annotation using the
Annotations
button in the upper right corner of the service, and define any variables the service needs by clicking theVariables
button in the upper left corner.A new resource is added automatically with the service. This happens because a resource is required if you need to invoke something or get something back from the service. 1. You can rename the service by providing an appropriate name. 1. You can also rename the resourse to something appropriate.
You can start adding your integration logic.
Add integration logic to your service
Now that you have added a service, you must set up this service so that it can be used in your integration scenario.
- Select an HTTP identifier from the dropdown available. In this case, you can use GET as the HTTP verb, since you are aiming to get the information using a URL. If you use both a GET and a POST, you need to add a new resource. You can add more resources by dragging them from the tool palette and adding them to the service.
- As mentioned in About service URLs, the path for the books service is
http://localhost:9090/books
. Add an annotation by clicking on the label in the service and selectingballerina.net.http
from the dropdown. -
Once you add the annotation, you are asked to add an identifier. Select
config
as the identifier from the dropdown.1. Click the
+
sign and selectbasePath
from the dropdown to select the basepath. 1. Enter the base path as/books
to definehttp://localhost:9090/books
as the service. 1. Add an annotation to the service itself by clicking the label in the service and selectingballerina.net.http
from the dropdown.1. Add a HTTP Path from the dropdown that appears. 1. Click the
+
sign next to@Http:Path
and select value in the dropdown that appears. Define the value as/title
and assign it to the HTTP Path variable. This enables the Ballerina service and the resource to be mapped properly to the title of the book. This is linked to the URL to be called:http://localhost:9090/books/title
.
View the Swagger definition for your service
If your Ballerina program contains services and resources, you can view the generated Swagger definition for your program by switching to the Swagger view. All the changes made on the Swagger definition will reflect on the Ballerina program when you switch back to Source or Design view.
You can also import Swagger files by clicking File in the top menu and selecting Import Swagger.
-
Click the Swagger definition icon on the right of your service to view the Swagger definition. You can switch back to the Design View or Source View by clicking the buttons at the bottom right of your screen.
The Swagger UI Editor provides numerous usage options to easily interact with APIs. 1. Click
GET
to see the details in the Swagger UI.
Add a client connector
Now that you have added a service, you need a connector to connect to the external books API.
- On the tool palette, click More Connectors to see a list of all available connectors.
- From the list that appears, expand ballerina.net.http and drag a ClientConnector onto the canvas.
- Add the endpoint URL (https://www.googleapis.com/books/v1/) within quotation marks "" as the connector endpoint. You can also change the name of the endpoint to something suitable. > The endpoint URL, in this instance, is not the complete URL and does not include the title or the book and other details. You can directly add the complete URL here if you wish. This is not done in this scenario for the purposes of the tutorial and to highlight a different means of achieving the same outcome, i.e., the title will be appended in the request.
Call the client connector
- Add a HTTP GET request by dragging it from the tool palette to the canvas.
- To call the connector from the main program, draw an arrow to the connector from the GET action.
- Pass a message from the main program to the connector by specifying the remaining part of the endpoint URL (volumes?q=intitle:wso2) and message
m
. Also rename the HTTP GET message name tom
. > Note that a message is passed by default in a service. This will not be the case in a main program application. In this case, it is messagem
that is passed. The full endpoint URL is https://www.googleapis.com/books/v1/volumes?q=intitle:wso2. - Add the query parameter to the resource by going to the source view and modifying the resource to the following.
resource getBooksByTitle (message m, @http:QueryParam {value:"title"} string title)
- Now that you have specified a query parameter, you can use the value of the query parameter in your connector call. Change the message passed to the following.
Extract content from the JSON
- Use the search, or navigate to a function called
getJsonPayload
, which is in theballerina.lang.messages
library. This library contains functions that enable you to modify and use messages in various ways. - Drag and drop this onto the main program in the canvas. This automatically applies this function on message m since that is the default message.
-
Rename the JSON as
j
.1. Add a variable from the tool palette to the main function in the canvas. 1. Modify the variable so that you can get the data under list. In this example,
.list
is a JSON path.json bookList = j.items

This is not an assignment, but I suggest that you do install the Guest Additions.
If you set up the VirtualBox Guest Additions in Linux, you will find that you have better control over your virtual machine. In particular, you will find it easier to resize your desktop or make it full screen. You should also have better control over the mouse.
Having a copy of JsObjects on your various machines can be useful, as it contains many helpful examples. For instance, when you create a new Virtual Machine, you probably want to have JsObjects installed on it. Here is a brief review of how you can, as necessary, install Git:
sudo apt-get install git
Now navigate to place on your hard drive where you can clone JsObjects. On Linux, that would usually be a folder called Git or GitHub. Here is how to create the folder:
mkdir ~/Git
Now navigate to that folder:
cd ~/Git
And then clone my repo:
git clone git://github.com/charliecalvert/JsObjects.git
You want to be sure that your copy of Linux has SSH installed. Here is the command to install SSH:
sudo apt-get install ssh
Here are two commands that create a pulic and private key for your Linux box, and save them in your .ssh folder:
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

With more than 60 million websites, WordPress is the most popular CMS currently in use but it’s also based on the most hacked environment aka LAMP.
As we all know, there is no way to stop a determined hacker but you can slow him down or detect him before things become serious. Below some techniques to improve the security of your site. This post is directly inspired from Wordpress official codex and some hackers techniques I learned last months.
According to Worpdress documentation, and I won’t discuss this point here, directories must have the following permission: drwxr-xr-x
(755) and files must be: -rw-r--r--
(644).
Wordpress says that automatic update changes file/dir permissions, that’s true but not that way in my case, maybe a cron job could do it ?
It’s very important that your database is protected with strong credentials, check the post about how to choose a good password. Keep in mind that a SQL user must be only used for one application and must not have administrator privileges.
It’s also possible to change the table prefix which is wp_
by default, this will prevent from automatic SQL injection attacks.
However this must be done while performing the installation, it’s too hard/dangerous to change that parameter on a running app.
Backup your database very often, once a week is a good average but it actually depends on your post frequency. Of course the data files must not be saved under the web tree.
When a new bug is found it’s quickly registered on many security listing. Years later, it’s still there with the list of infected versions.
Keep your Wordpress up to date. For each new release you’ll get a warning in your dashboard. If you have automatic update enable (implemented in version 3.7), you’ll receive a message but you’ll not need to do anything.
It can be usefull to hide the current version of your Wordpress with this small script in functions.php
:
function remove_wp_version_tag() {
return null;
}
add_filter( 'the_generator', 'remove_wp_version_tag' );
The point here is to hide usernames as much as possible.
Rename the default user admin to whatever you want because this username is the first target of a brute force attack.
Give your users a nickname, which should be selected as public and different than the username.
Disable authors dedicated page with this small script in functions.php
:
add_action('template_redirect', 'bwp_template_redirect');
function bwp_template_redirect() {
global $wp_query, $post;
if (is_author() ) {
$wp_query->set_404();
}
}
You can also remove the tag <dc:creator>
from all feed: wp-admin/includes/export.php
, wp-includes/feed-rss2-comments.php
,
wp-includes/feed-rss2.php
and wp-includes/feed-rdf.php
however those files could be overwrited at the next update.
Of course users must have a strong password, a single user access, even with low privileges, can be deadly.
It’s very important to stay aware about updates, most of the times they fixe small bugs but sometimes it’s about security. You wouldn’t keep a Local File Inclusion because of a gallery plugins, even if it’s disable. Btw remove disabled plugins/themes, you don’t need them and you probably won’t care about patches…
Try to hide the current version of your plugins and themes by removing .txt
files who disclose to much infos (versions, patches, bugs, …) as well as most .html
files.
Those two functions prevent display of version numbers in the html source of your site, in functions.php
:
function remove_wp_version_strings( $src ) {
global $wp_version;
parse_str(parse_url($src, PHP_URL_QUERY), $query);
if ( !empty($query['ver']) && $query['ver'] === $wp_version ) {
$src = remove_query_arg('ver', $src);
}
return $src;
}
add_filter( 'script_loader_src', 'remove_wp_version_strings' );
add_filter( 'style_loader_src', 'remove_wp_version_strings' );
// remove wp version param from any enqueued scripts
function vc_remove_wp_ver_css_js( $src ) {
if ( strpos( $src, 'ver=' ) )
$src = remove_query_arg( 'ver', $src );
return $src;
}
add_filter( 'style_loader_src', 'vc_remove_wp_ver_css_js', 9999 );
add_filter( 'script_loader_src', 'vc_remove_wp_ver_css_js', 9999 );
To protect admin section you can restrict wp-admin
directory and wp-login.php
to trusted IP address. In /.htaccess
:
<filesmatch "wp-login"="">
order deny,allow
deny from all
allow from xxx.xxx.xxx.xxx
</filesmatch>
In /wp-admin/.htaccess
:
order deny,allow
deny from all
allow from xxx.xxx.xxx.xxx
To prevent brute force, and if you have a server with fail2ban installed, there is a Wordpress plugin planned to interact with it: Wordpress fail2ban plugin (the installation requires root access to the server).
To test all changes you can use WPScan, this tool is a great WordPress vulnerability scanner.


Sprint 43 review - July 13, 2016
There is a ManageIQ Sprint review every 3 weeks, and everyone in the community is welcome to participate. To join our Sprint review meeting, please use this Bluejeans link.
For Sprint 43, we merged 329 pull requests, making this a regular sprint averaging 100 PRs per week. There is a good distribution between new features, bug fixes, and code refactoring. We have plenty of enhancements on the Providers side, including Amazon, Networking, and Hawkular. Work has started on a Service Broker, which is a new piece for ManageIQ to allow VM selection based on criteria you provide.
SmartState has been extended with a generalized disk LRU caching module, which will be employed to address Azure performance and throttling issues. PostgreSQL has been upgraded to 9.5. There are also many User Interface updates, explained in detail in the following video recording of the meeting, including a couple of demos in the Providers area (Recheck Authentication and Credentials Validation).
As we had audio issues during this meeting with people dropping in and out, some of the presentations were not in the order laid out in the agenda. Here is the actual order with the corresponding timestamps for each section:
- Sprint Statistics (Oleg Barenboim) - 0:53
- Community Update (Carol Chen) - 4:54
- Providers (Bronagh Sorota, Alissa Bonas, Greg McCullough) - 8:38
- Automate (Greg McCullough, Madhu Kanoor) - 14:35
- User Interface (Dan Clarizio) - 21:27
- Platform (Gregg Tanzillo) - 35:12
- Service Broker (Chris Kacerguis) - 38:35
- SmartState (Rich Oliveri) - 39:14
- Performance (Dennis Metzger) - 41:17
- REST API (Alberto Bellotti) - separate video
On June 30, we released Darga 2 containing mainly bug fixes and stabilization. With already over 200 PRs backported, we’ll continute to stabilize Darga 3 aimed for an end-August release.
In case you missed it, we also started a new blog series, “Last week in ManageIQ”, where select pull requests from the codebase are featured weekly. As it’s impractical to go through all the 300+ contributions during Sprint reviews, this is a great way to check out some highlights each week. The first post was published this Tuesday. We hope you’ll find it interesting and useful!
Sprint 44 review will be on August 3, 2016 @ 7:30am PDT/10:30am EDT/14:30 GMT. You can import the ManageIQ community calendar to be notified about this and future Sprint reviews.

Distance calculation for xy points or xyz points is done by taking the square root. However, for distance comparison drawing the square root is not necessary. Therefore the distance strategies are allowed to return the squares of the distance. This structure contains the distance, and a boolean to indicate if it is squared. It has an automatic conversion to a double value, which does the square root if necessary.

Men splash dirt, offer water, flee with Rs 2.5L cash
Sleight of hand
by Umesh R YadavSpraying dirt on a 22-year-old man walking out of a bank in Banaswadi, two men offered him water to wash and fled with the cash bag as he was cleaning the dirt.
Victim Amal Vincent told police that he works as an office boy at a garment factory owned by Jaison Anthony. On Monday, he was sent to the bank to withdraw cash to pay the salary for the workers.
At 12.30 pm, Vincent withdrew Rs 2.54 lakh from Syndicate Bank on Banaswadi Main Road. He placed the cash in a bag and exited the bank.
A man who stood at the gate told Vincent that there was dirt on his shirt and offered a bottle of water to clean. As Vincent placed the bag down to clean, the man picked it up and ran. Vincent chased him on the bike but was caught in the traffic signal. The man escaped with an accomplice on the bike waiting on the other side of the road.
Vincent informed his owner and filed a complaint at the Banaswadi police station. He told the police that the man spoke in Kannada.
In yet another case, 62-year-old retired employee Subramani, a resident of Sultanpalya, lost Rs 50,000 he kept in the boot space of his scooter. The theft happened at RT Nagar on Monday evening.
CCTV footage taken from a supermarket showed two men opening the seat attached to the boot space of Subramani’s scooter and taking away the cash.
RT Nagar police suspect the involvement of local people in the crime and assured that they are making all efforts to nab the culprits.


Libya’s Coast Guard Intercepts 284 Europe-Bound Migrants
CAIRO (AP) — Libya’s coast guard says it has intercepted 284 Europe-bound migrants off the country’s Mediterranean coast.
by Breitbart LondonSaturday’s statement says the migrants were intercepted in four separate operations off the coastal towns of Zawya, Garabulli and Abu-Kemmash, and the city of Tripoli. The four boats were stopped Wednesday.
The statement says the migrants were handed over to authorities in Tripoli and were taken to detention centers.
Libya has emerged as a major transit point for migrants fleeing war and poverty to Europe. In recent years, the EU has partnered with Libya’s coast guard and other local groups to stem the dangerous sea crossings.
Rights groups, however, say those policies leave migrants at the mercy of armed groups or confined in squalid detention centers rife with abuses.

type-check
is a library which allows you to check the types of JavaScript values at runtime with a Haskell like type syntax. It is great for checking external input, for testing, or even for adding a bit of safety to your internal code. It is a major component of levn. MIT license. Version 0.3.2. Check out the demo.
For updates on type-check
, follow me on twitter.
npm install type-check
```js // Basic types: var typeCheck = require(‘type-check’).typeCheck; typeCheck(‘Number’, 1); // true typeCheck(‘Number’, ‘str’); // false typeCheck(‘Error’, new Error); // true typeCheck(‘Undefined’, undefined); // true
// Comment typeCheck(‘count::Number’, 1); // true
// One type OR another type: typeCheck(‘Number | String’, 2); // true typeCheck(‘Number | String’, ‘str’); // true
// Wildcard, matches all types: typeCheck(‘*’, 2) // true
// Array, all elements of a single type: typeCheck(‘[Number]’, [1, 2, 3]); // true typeCheck(‘[Number]’, [1, ‘str’, 3]); // false
// Tuples, or fixed length arrays with elements of different types: typeCheck(‘(String, Number)’, [‘str’, 2]); // true typeCheck(‘(String, Number)’, [‘str’]); // false typeCheck(‘(String, Number)’, [‘str’, 2, 5]); // false
// Object properties: typeCheck(‘{x: Number, y: Boolean}’, {x: 2, y: false}); // true typeCheck(‘{x: Number, y: Boolean}’, {x: 2}); // false typeCheck(‘{x: Number, y: Maybe Boolean}’, {x: 2}); // true typeCheck(‘{x: Number, y: Boolean}’, {x: 2, y: false, z: 3}); // false typeCheck(‘{x: Number, y: Boolean, …}’, {x: 2, y: false, z: 3}); // true
// A particular type AND object properties: typeCheck(‘RegExp{source: String, …}’, /re/i); // true typeCheck(‘RegExp{source: String, …}’, {source: ‘re’}); // false
// Custom types: var opt = {customTypes: {Even: { typeOf: ‘Number’, validate: function(x) { return x % 2 === 0; }}}}; typeCheck(‘Even’, 2, opt); // true
// Nested: var type = ‘{a: (String, [Number], {y: Array, …}), b: Error{message: String, …}}’ typeCheck(type, {a: [‘hi’, [1, 2, 3], {y: [1, ‘ms’]}], b: new Error(‘oh no’)}); // true ```
Check out the type syntax format and guide.
require('type-check');
returns an object that exposes four properties. VERSION
is the current version of the library as a string. typeCheck
, parseType
, and parsedTypeCheck
are functions.
```js // typeCheck(type, input, options); typeCheck(‘Number’, 2); // true
// parseType(type); var parsedType = parseType(‘Number’); // object
// parsedTypeCheck(parsedType, input, options); parsedTypeCheck(parsedType, 2); // true ```
typeCheck
checks a JavaScript value input
against type
written in the type format (and taking account the optional options
) and returns whether the input
matches the type
.
String
- the type written in the type format which to check against*
- any JavaScript value, which is to be checked against the typeMaybe Object
- an optional parameter specifying additional options, currently the only available option is specifying custom typesBoolean
- whether the input matches the type
js
typeCheck('Number', 2); // true
parseType
parses string type
written in the type format into an object representing the parsed type.
String
- the type written in the type format which to parseObject
- an object in the parsed type format representing the parsed type
js
parseType('Number'); // [{type: 'Number'}]
### parsedTypeCheck(parsedType, input, options)
parsedTypeCheck
checks a JavaScript value input
against parsed type
in the parsed type format (and taking account the optional options
) and returns whether the input
matches the type
. Use this in conjunction with parseType
if you are going to use a type more than once.
Object
- the type in the parsed type format which to check against*
- any JavaScript value, which is to be checked against the typeMaybe Object
- an optional parameter specifying additional options, currently the only available option is specifying custom typesBoolean
- whether the input matches the type
js
parsedTypeCheck([{type: 'Number'}], 2); // true
var parsedType = parseType('String');
parsedTypeCheck(parsedType, 'str'); // true
White space is ignored. The root node is a Types.
[\$\w]+
- a group of any lower or upper case letters, numbers, underscores, or dollar signs - eg. String
Identifier
, an Identifier
followed by a Structure
, just a Structure
, or a wildcard *
- eg. String
, Object{x: Number}
, {x: Number}
, Array{0: String, 1: Boolean, length: Number}
, *
Indentifier
followed by a ::
), optionally the identifier Maybe
, one or more Type
, separated by |
- eg. Number
, String | Date
, Maybe Number
, Maybe Boolean | String
Fields
, or a Tuple
, or an Array
- eg. {x: Number}
, (String, Number)
, [Date]
{
, followed one or more Field
separated by a comma ,
(trailing comma ,
is permitted), optionally an ...
(always preceded by a comma ,
), followed by a }
- eg. {x: Number, y: String}
, {k: Function, ...}
Identifier
, followed by a colon :
, followed by Types
- eg. x: Date | String
, y: Boolean
(
, followed by one or more Types
separated by a comma ,
(trailing comma ,
is permitted), followed by a )
- eg (Date)
, (Number, Date)
[
followed by exactly one Types
followed by a ]
- eg. [Boolean]
, [Boolean | Null]
type-check
uses Object.toString
to find out the basic type of a value. Specifically,
js
{}.toString.call(VALUE).slice(8, -1)
{}.toString.call(true).slice(8, -1) // 'Boolean'
A basic type, eg. Number
, uses this check. This is much more versatile than using typeof
- for example, with document
, typeof
produces 'object'
which isn’t that useful, and our technique produces 'HTMLDocument'
.
You may check for multiple types by separating types with a |
. The checker proceeds from left to right, and passes if the value is any of the types - eg. String | Boolean
first checks if the value is a string, and then if it is a boolean. If it is none of those, then it returns false.
Adding a Maybe
in front of a list of multiple types is the same as also checking for Null
and Undefined
- eg. Maybe String
is equivalent to Undefined | Null | String
.
You may add a comment to remind you of what the type is for by following an identifier with a ::
before a type (or multiple types). The comment is simply thrown out.
The wildcard *
matches all types.
There are three types of structures for checking the contents of a value: ‘fields’, ‘tuple’, and ‘array’.
If used by itself, a ‘fields’ structure will pass with any type of object as long as it is an instance of Object
and the properties pass - this allows for duck typing - eg. {x: Boolean}
.
To check if the properties pass, and the value is of a certain type, you can specify the type - eg. Error{message: String}
.
If you want to make a field optional, you can simply use Maybe
- eg. {x: Boolean, y: Maybe String}
will still pass if y
is undefined (or null).
If you don’t care if the value has properties beyond what you have specified, you can use the ‘etc’ operator ...
- eg. {x: Boolean, ...}
will match an object with an x
property that is a boolean, and with zero or more other properties.
For an array, you must specify one or more types (separated by |
) - it will pass for something of any length as long as each element passes the types provided - eg. [Number]
, [Number | String]
.
A tuple checks for a fixed number of elements, each of a potentially different type. Each element is separated by a comma - eg. (String, Number)
.
An array and tuple structure check that the value is of type Array
by default, but if another type is specified, they will check for that instead - eg. Int32Array[Number]
. You can use the wildcard *
to search for any type at all.
Check out the type precedence library for type-check.
Options is an object. It is an optional parameter to the typeCheck
and parsedTypeCheck
functions. The only current option is customTypes
.
Example:
js
var options = {
customTypes: {
Even: {
typeOf: 'Number',
validate: function(x) {
return x % 2 === 0;
}
}
}
};
typeCheck('Even', 2, options); // true
typeCheck('Even', 3, options); // false
customTypes
allows you to set up custom types for validation. The value of this is an object. The keys of the object are the types you will be matching. Each value of the object will be an object having a typeOf
property - a string, and validate
property - a function.
The typeOf
property is the type the value should be, and validate
is a function which should return true if the value is of that type. validate
receives one parameter, which is the value that we are checking.
type-check
is written in LiveScript - a language that compiles to JavaScript. It also uses the prelude.ls library.

Giotto is a domain designed by Christoph Meyer Kirsch to realize the semantics of the Giotto language, designed by Tom Henzinger, Ben Horowitz, and Christoph Meyer Kirsch. The semantics is a particular flavor of a synchronous model. Each component executes a specified number of times per iteration. The number of times it executes is called its frequency, and it defaults to one. The frequency can be specified to be something other than one by simply adding a parameter to the component named frequency, and then giving it a value different from one.
A particular feature of Giotto semantics is that the arcs connecting components are updated with a new value at well-defined points in the execution, irrespective of their execution time. If the frequency of the actor producing the data for the arc is one, then the value is updated only between iterations. Thus, each arc begins empty (having no value present), and acquires a value at the end of the first iteration.
If a component has frequency greater than one, then its output arcs are updated more than once per iteration. Suppose the frequency is two. Then its output arcs will be updated twice per iteration, but only the final update will be visible to components with frequency one (and only on the next iteration). If a component with frequency two is a destination of one of its outputs, then that component will see each update, but only in its next invocation. Thus, the second invocation of the destination in the iteration will see the value produced by the first invocation of the source in the iteration.
Giotto imposes the additional constraint that the frequencies of all components in a model bear harmonic relationships with one another. This means, for example, that frequencies of 2 and 3 cannot coexist in the same model. Frequencies 2 and 4 or 3 and 6 can, however, coexist.
The Giotto domain is highly preliminary, and the example models are not particularly interesting. Watch this space for more interesting examples.

Example: if the inspection is enabled for tests and specifies the min class name length 8 (the default) the following test class
public class MyTest{}
produces a warning because the length of it's name is 6 which is less than 8.
Quick-fix to rename the class is suggested only in the editor.
Use the list below to specify which classes should be checked. When the checkbox for the class type is unchecked, checks for this kind of classes are skipped. For each class type use the fields to specify minimum length, maximum length and regular expression expected for class names. Specify 0 in length fields to skip corresponding checks.

Containerizing an Application
In this exercise, you'll be provided with the application logic of a simple three tier application; your job will be to write Dockerfiles to containerize each tier, and write a Docker Compose file to orchestrate the deployment of that app. This application serves a website that presents cat gifs pulled from a database. The tiers are as follows:
- Database: Postgres 9.6
- API: Java SpringBoot built via Maven
- Frontend: NodeJS + Express
Basic success means writing the Dockerfiles and docker-compose file needed to deploy this application to your orchestrator of choice; to go beyond this, think about minimizing image size, maximizing image performance, and making good choices regarding configuration management.
Start by cloning the source code for this app:
[centos@node-0 ~]$ git clone -b ee2.1 \
https://github.com/docker-training/fundamentals-final.git
Containerizing the Database
Navigate to
fundamentals-final/database
to find the config for your database tier.Begin writing a Dockerfile for your postgres database image by choosing an appropriate base image.
Your developers have provided you with postgres configuration files
pg_hba.conf
andpostgresql.conf
. Both of these need to be present in/usr/share/postgresql/9.6/
.You have also been provided with
init-db.sql
. This SQL script populates your database with the required cat gifs. Read the docs for Postgres and / or your base image to determine how to run this script.Postgres expects the environment variables
POSTGRES_USER
andPOSTGRES_DB
to be set at runtime. Make sure these are set togordonuser
andddev
, respectively, when your database container is running.Once you've built your image, try running it, connecting to it, and querying the postgres database to make sure it's up and running as you'd expect:
[centos@node-0 ~]$ docker container run --name database -d mydb:latest [centos@node-0 ~]$ docker container exec -it database bash [root@641172f742a5 /]# psql ddev gordonuser -c 'select * from images;'
If everything is working correctly, you should see a table with URLs to cat gifs returned by the query. Exit and delete this container once you're satisfied that it is working correctly.
Containerizing the API
Navigate to
fundamentals-final/api
to find the source and config for your api tier.We intend to build this SpringBoot API with Maven. Begin writing a Dockerfile for your API by choosing an appropriate base image for your build environment.
Your developers gave you the following pieces of information:
- Everything Maven needs to build our API is in
fundamentals-final/api
. - The Maven commands to build your API are:
$ mvn -B -f pom.xml -s /usr/share/maven/ref/settings-docker.xml dependency:resolve $ mvn -B -s /usr/share/maven/ref/settings-docker.xml package -DskipTests
- This will produce a jar file
target/ddev-0.0.1-SNAPSHOT.jar
at the path where you ran Maven. - In order to successfully access Postgres, the execution environment for your API should be based on Java 8 in an alpine environemnt, and have the user
gordon
, as per:
$ adduser -Dh /home/gordon gordon
- The correct command to launch your API after it's built is:
$ java -jar <path to jar file>/ddev-0.0.1-SNAPSHOT.jar \ --spring.profiles.active=postgres
Use this information to finish writing your API Dockerfile. Mind your image size, and think about what components need to be present in production.
- Everything Maven needs to build our API is in
Once you've built your API image, set up a simple integration test between your database and api by creating a container for each, attached to a network:
[centos@node-0 ~]$ docker network create demo_net [centos@node-0 ~]$ docker container run \ -d --network demo_net --name database mydb:latest [centos@node-0 ~]$ docker container run \ -d --network demo_net -p 8080:8080 --name api myapi:latest
Curl an API endpoint:
[centos@node-0 ~]$ curl localhost:8080/api/pet
If everything is working correctly, you should see a JSON response containing one of the cat gif URLs from the database. Leave this integration environment running for now.
Containerizing the Frontend
Navigate to
fundamentals-final/ui
to find the source and config for your web frontend.You know the following about setting up this frontend:
- It's a node application.
- The filesystem structure under
fundamentals-final/ui
is exactly as it should be in the frontend's running environment. - Install proceeds by running
npm install
in the same directory aspackage.json
. - The frontend is started by running
node src/server.js
.
Write a Dockerfile that makes an appropriate environment, installs the frontend and starts it on container launch.
Once you've built your ui image, start a container based on it, and attach it to your integration environment from the last step. Check to see if you can hit your website in your browser at
IP:port/pet
; if so, you have successfully containerized all three tiers of your application.
Orchestrating the Application
Once all three elements of the application are containerized, it's time to assemble them into a functioning application by writing a Docker compose file. The environmental requirements for each service are as follows:
- Database:
- Named
database
. - Make sure the environment variables
POSTGRES_USER
andPOSTGRES_DB
are set in the compose file, if they weren't set in the database's Dockerfile (when would you want to set them in one place versus the other?). - The database will need to communicate with the API.
- Named
- API:
- Named
api
. - The API needs to communicate with both the database and the web frontend.
- Named
- Frontend:
- Named
ui
. - Serves the web frontend on container port 3000.
- Needs to be able to communicate with the API.
- Named
Write a docker-compose.yml
to capture this configuration, and use it to stand up your app with Docker Compose, Swarm, or Kubernetes. Make sure the website is reachable from the browser.
Conclusion
In this exercise, you containerized and orchestrated a simple three tier application by writing a Dockerfile for each service, and a Docker Compose file for the full application. In practice, developers should be including their Dockerfiles with their source code, and senior developers and / or application architects should be providing Docker Compose files for the full application, possibly in conjunction with the operations team for environment-specific config.
Compare your Dockerfiles and Docker Compose file with other people in the class; how do your solutions differ? What are the possible advantages of each approach?


Designer | Developer I can code in the following programming languages:
Slipkart
The outcome of a soccer-related joke with a friend, SLIPKART became my CBSE Informatics Practices Project. It is an e-Commerce app for the sale of sports equipment. The frontend used is JAVA Netbeans, and the backend used is MySQL, connected through JDBC.
Tribute Page
I made a tribute page for the best player to ever grace a soccer pitch: Leo Messi. It includes a timeline of his life. I used HTML5 and CSS, and made it responsive with Bootstrap.
