Pupu
问题描述 :
But there is a question, when does an infant PuPu become an adult PuPu?
Aha, we already said, PuPu is a special animal. There are several skins wraping PuPu’s body, and PuPu’s skins are special also, they have two states, clarity and opacity. The opacity skin will become clarity skin if it absorbs sunlight a whole day, and sunshine can pass through the clarity skin and shine the inside skin; The clarity skin will become opacity, if it absorbs sunlight a whole day, and opacity skin will keep sunshine out.
when an infant PuPu was born, all of its skins were opacity, and since the day that all of a PuPu’s skins has been changed from opacity to clarity, PuPu is an adult PuPu.
For example, a PuPu who has only 3 skins will become an adult PuPu after it born 5 days(What a pity! The little guy will sustain the pressure from life only 5 days old)
Now give you the number of skins belongs to a new-laid PuPu, tell me how many days later it will become an adult PuPu?

Police Accessibility in Sweden: An Analysis of the Spatial Arrangement of Police Services


How did the 'process over product' concept affect the way you tackled the site redesign and rebuild?
Looking back, I feel the design process took a product focused approach. This was due in part to the nature of the task, implementing features I added to my wishlist from the CSS Zen Garden website audit.
Using inspiration taken from the CSS Zen Garden websites, had a strong influence on the final product. To implement some of the features, I designed my wireframes to accommedate those features for both desktop and mobile.


Forms9Patch Popups
Yet another thing missing from Xamarin Forms is a comprehensive set of popup views. Forms9Patch has a eight (ModalPopup, BubblePopup, FlyoutPopup, Toast, TargetedToast, PermissionPopup, ActivityIndicatorPopup and TargetedMenu) popups to simplify the most common tasks. However, this comes at a price! Forms9Patch popups (like a number of other Forms9Patch elements) use Forms9Patch.Image - which means Forms9Patch popups are IDisposable
. There is an upside to this. See the Memory Management for more information.
Android Note
You will need to add the following OnBackButtonPressed
code to your Android application's MainActivity
in order to have popups respond to the Android hardware backbutton.
public class MainActivity : FormsApplicationActivity
{
...
public override void OnBackPressed()
{
if (Forms9Patch.Popup.SendBackPressed(base.OnBackPressed))
{
// do something here if there are some popups in the popup stack
}
else
{
// do something else if there are not any popups in the popup stack
}
}
...
}
Common Properties, Methods and Events
The following properties and methods are common to all Forms9Patch popups, except ActivityIndicatorPopup
:
Common Appearance Properties
BackgroundImage
: TheForms9Patch.Image
displayed as the popup's background.BackgroundColor
: popup's optional background color.PopAfter
: theTimeSpan
, after appearing, at which the popup will pop (disappear) without user interaction. Popup will not pop itself whenPopAfter
is zero (default) or negative.HasShadow
: one more time ... this actually works on Android. Has no effect when BackgroundColor has not been set.OutlineColor
: optional outline color.OutlineWidth
: width of optional outline.OutlineRadius
: outline's corner radius.ShadowInverted
: to apply a recessed effect to the layout (if HasShadow is enabled).
Page Overlay (between the popup and the page the popup sets upon) Properties
PageOverlayColor
: The Color of the page overlay upon which the ModalPopup sets. Default value isColor.Rgba(0.5, 0.5, 0.5, 0.5)
.CancelOnBackgroundTouch
: Controls is the popup is cancelled if the background is touched. Default value is true.CancelOnBackButtonTouch
: Controls is the popup is cancelled if the back button (Android only) is touched. Default value is true.
Common Memory Management Properties
Retain
: a boolean (default:false
) used to indicate if the popup and its contents should be removed from the view hierarchy as soon as the view is hidden. Why would I bother to have this? ANDROID! If you have a heavy layout that will be shown multiple times, you may not want to re-render each time it is made visible. SeeingRetain=true
will keep your popup and its content in the view hierarchy so it won't have to be re-rendered the next time you want to present it.
Common Methods
void Cancel()
: Programmatically cancels the Popup.
Common Events
Cancelled
: Called when the popup has been canceled by the user tapping outside its bounds.
Forms9Patch.ModelPopup
The most needed missing component: a simple content popup that is a content container which centers its contents on the main page. Since you may want a popup container with a background image, Forms9Patch provides the ModalPopup element for this purpose. Once you have initialized a Forms9Patch popup view, set the IsVisible property to true to present it.
Forms9Patch.ModelPopup Unique Properties
Content
: TheXamarin.Forms.VisualElement
that will be the content for the popup view. Layouts and Views are fair game.ElementShape
:ElementShape.Rectangle
,ElementShape.Square
,ElementShape.Circle
,ElementShape.Ellipse
, andElementShape.Obround
. Controls the shape of both the border and the background clipping region.
Forms9Patch.BubblePopup
The popup that is missing from both Xamarin.Forms and Android is a pointer bubble popup - a popup that points to another element. Given a Target
element, some Content
to display, and an allowed PointerDirection
, Forms9Patch.BubblePopup
will best fit a popup bubble pointing the the Target
. Note that, unlike the ModalPopup
element, BubblePopup
does not support the BackgroundImage
nor ElementShape
properties. If you do not specify the Target
, BubblePopup
will present its content in a ModalPopup
. As with ModalPopup
, once you have initialized a BubblePopup
you will need to set the IsVisible
property to true
to present it.
Forms9Patch.BubblePopup Unique Properties
Content
: TheVisualElement
that will be the content for the popup view. Layouts and Views are fair game.Target
: TheXamarin.Forms.VisualElement
to which the bubble popup will point.PointerLength
: how long is the pointer.PointerTipRadius
: what is the radius of the pointer's tip?PointerDirection
: what directions is the bubble popup allow to point? Type:PointerDirection
PointerCornerRadius
: what is the radius of the notch between the bubble's body and the pointer?
Forms9Patch.FlyoutPopup
Another popup missing is a flyout - to present content such as menus or master control views. Give Forms9Patch.FlyoutPopup
some content to display, set IsVisible=true
and it will by default have it flyout from the left edge of the current Page. Change the Orientation
property to have the flyout come from left/right (Horizontal
) or top/bottom (Vertical
). Change the Alignment
property to switch between left or right (Start
or End
) for Horizontal
orientation and between top or bottom (Start
or End
) for Vertical
orientation. Want to be sure the width (for Horizontal
orientation) is fixed? Set the WidthRequest
of your Content
and it will use that to determine the flyout's width. Likewise, set the Content's
HeightRequest
for Vertical
flyouts.
Note that FlyoutPopup also does the hard work of figuring out where the SafeArea is for your content. You can see that in action in the below GIF.
Forms9Patch.FlyoutPopup Unique Properties
Content
: TheVisualElement
that will be the content for the popup view. Layouts and Views are fair game.Orientation
: Is the popup going to fly in horizontally or vertically?Alignment
: Is the popup going to be at the left\top (Start
) or right\bottom (End
)
Forms9Patch.Toast
Sometimes you simply need to put a message up on the screen. Given some HTML formatted text and an HTML formatted title Toast
will display them in a popup with an (optional but enabled by default) [OK] button. Toast
is inherited from the ModalPopup
element so it does support background images. Unlike ModalPopup
, Toast
has the Create(string title, string text)
static method that will generate and present the toast. You can still manually construct and present a Toast
by using its constructor and setting its IsVisible
property to true.
Forms9Patch.Toast Unique Properties
Title
: The title for the Toast. See HTML Markup for supported markup.Text
: The text for the Toast. See HTML Markup for supported markup.ElementShape
:ElementShape.Rectangle
,ElementShape.Square
,ElementShape.Circle
,ElementShape.Ellipse
, andElementShape.Obround
. Controls the shape of both the border and the background clipping region.
Forms9Patch.Toast Unique Methods
static Toast Create(string title, string text)
: instantiates and presents aToast
.
Forms9Patch.TargetedToast
Just as Toast
is a convenience version of ModalPopup
, TargetedToast
is a convenience version of BubblePopup
. Given a Target
as a Xamarin.Forms.VisualElement
, a Title
, some Text
to display, and an allowed PointerDirection
, Forms9Patch.TargetedToast
will best fit a popup bubble pointing the the Target
. Like BubblePopup
element, BubblePopup
does not support background images. If you do not specify the Target
, it will present itself as a Toast
. As with Toast
, you can use the Create
static method to instantiate and present a TargetedToast
.
Forms9Patch.TargetedToast Unique Properties
Title
: The title for the Toast. See HTML Markup for supported markup.Text
: The text for the Toast. See HTML Markup for supported markup.Target
: TheXamarin.Forms.VisualElement
to which the bubble popup will point.OkButtonColor
: Background color for [OK] button.OkTextColor
: Text color for [OK] button.OKText
: Text for [OK] button. Set to null to remove the [OK] button from the popup. As noted above, you don't want this set to null whenCancelOnBackgroundTouch
is set tofalse
.
Forms9Patch.TargetedToast Unique Methods
static TargetedToast Create(VisualElement target, string title, string text)
: instantiates and presents aTargetedToast
.
Forms9Patch.PermissionPopup
Sometimes you simply need to ask a yes/no question. Given some HTML formatted text and an HTML formatted title, PermissionPopup
will display them in a popup with [OK] and [Cancel] buttons. PermissionPopup
is inherited from the ModalPopup
element so it does support background images. Unlike ModalPopup
, PermissionPopup
has the Create(string title, string text)
static method that will generate and present the toast. You can still manually construct and present a PermissionPopup
by using its constructor and setting its IsVisible
property to true
. Unlike Toast
, the [OK] and [Cancel] buttons cannot be removed from the layout by setting their text to null.
Forms9Patch.PermissionPopup Unique Properties
Title
: The title for the Toast. See HTML Markup for supported markup.Text
: The text for the Toast. See HTML Markup for supported markup.OkButtonColor
: Background color for [OK] button.OkTextColor
: Text color for [OK] button.OKText
: Text for [OK] button.CancelButtonColor
: Background color for [Cancel] button.CancelTextColor
: Text color for [Cancel] button.CancelText
: Text for [Cancel] button.PermissionState
: An enum (Pending
,Ok
,Cancelled
,Rejected
) describing the state of the permission granting process. This is very useful when thePermissionPopup
is wrapped in ausing
block and is examined after aWaitForCancelAsync()
call.
Forms9Patch.PermissionPopup Unique Methods
static PermissionPopup Create(string title, string text, string okText = "OK", string cancelText = "Cancel")
: instantiates and presents aPermissionPopup
.
Forms9Patch.PermissionPopup Unique Events
OkTapped
: Called when the [OK] button has been tapped.
Forms9Patch.TargetedMenu
Sometimes you need a popup menu with a list of menu items. And, if there are more menu items than available room, the menu needs to have pagination. Forms9Patch.TargetedMenu
combines SegmentedController
's use of a List<Segment>
to define the menu items with features of TargetedToast
to give this functionality.
Forms9Patch.TargetedMenu Unique Properties
Segments
: aList
ofForms9Patch.Segment
elements that define the menu items. See Forms9Patch.Segment for how to set a segment's text and icons.FontSize
: size of font to be used.TextColor
: color of text for each menu item.SeparatorColor
: color of separator line between menu itemsSeparatorWidth
: thickness of separator line between menu itemsHapticEffect
: if available on platform and enabled viaHapticMode
, what will be the haptic effect:None
, platform'sKeyClick
effect, platform'sReturn
key effect, or platformsDelete
key effect?HapticMode
: if available on platform, enable, disable, or use default behavior for the haptic effect.
Forms9Patch.TargetedMenu Unique Events
public event SegmentedControlEventHandler SegmentTapped
: fired when a menu item (segment) has been tapped.
Forms9Patch.ActivityIndicatorPopup
This popup is probably misnamed. Its purpose is to present an activity indicator and block interaction with the app. Because ModalPopup
had everything I needed to build this, I named it a popup. Probably should have thought about that more. Also, because this is something you typically just want to fire and forget, like Toast
and TargetedToast
, ActivityIndicatorPopup
has a Create
static method to instantiate and present an instance in one call.
Note that
Forms9Patch.ActivityIndicatorPopup Properties
PageOverlayColor
: TheColor
of the page overlay upon which theModalPopup
sets. Default value isColor.Rgba(0.5, 0.5, 0.5, 0.5)
.Color
:Color
of the activity indicator.CancelOnBackgroundTouch
: Controls is the popup is cancelled if the background is touched. Default value is true.
Forms9Patch.ActivityIndicatorPopup Methods
static ActivityIndicatorPopup Create()
void Cancel()
: Programmatically cancels the popup.
Forms9Patch.ActivityIndicatorPopup Events
Cancelled
: Called when the popup has been canceled by the user tapping outside its bounds.
Memory Management
With all Forms9Patch popup's, the good news is the using
keyword will make your life much easier. Additionally, Forms9Patch popups have the WaitForPoppedAsync
method to allow you to interact with the popup's content before disposal.
Forms9Patch.Toast is the simplest example:
using (Forms9Patch.Toast.Create("Updated","The list was updated.")) { }
In the above example, we're presenting a Toast and there is no need for our code to interact with its content. As such, the using
statement attempts to Dipose()
our Toast as soon as it can. This all happens because all Forms9Patch popups automatically add a WaitForPoppedAsync()
before completing the Dispose()
. In other words, the popup won't be disposed until the user takes action to dismiss the popup.
As a more interesting example, take a look at a sample usage of Forms9Patch.PermissionPopup:
using (var permissionPopup = Forms9Patch.PermissionPopup.Create(
"Unit Mismatch",
Items.Count((i) => !i.IsTemplate) > 1
? "This entry (" + operand.ToHtml() + ") does not have units but the existing Cumulative Memory entries do."
: "This entry (" + operand.ToHtml() + ") does not have units but the existing Cumulative Memory entry does.",
"YES"))
{
permissionPopup.Text += "\n\nDo you want to apply the last Cumulative Memory entry's units [" + firstItem.Value.UnitSet + "] to this entry?";
permissionPopup.Parameter = operand;
permissionPopup.IsVisible = true;
await permissionPopup.WaitForPoppedAsync();
if (permissionPopup.PermissionState == PermissionState.Ok)
{
if (operand is Expression expression)
expression.Complete();
operand.ApplyUnitSet(firstItem.Value.UnitSet);
return true;
}
}
In the above example, you can see that we are able to manipulate permissionPopup
and subscribe to its events. And, because await WaitForePoppedAsync()
is part of its Dispose()
, our subscriptions will remain valid up until the user interaction has been completed.
Please note that ActivityIndicatorPopup
is slightly different. That is because it can only be cancelled programmatically - not through direct user interaction. With that in mind and for ease of use, calling Dispose()
on an ActivityIndicatorPopup
will first implicitly call CancelAsync
on the ActivityIndicatorPopup
before it is disposed. This means you can use the asynchronous calls in the using
block to implicitly control the appearance / disappearance / disposal of the ActivityIndicatorPopup
. In the below example, the Create()
factory method generates the ActivityIndicatorPopup
and displays it. Then, after the GetDataAsync()
has completed, the using
block calls Dispose()
on our ActivityIndicatorPopup
- implicitly cancelling it before the disposal.
using (Forms9Patch.ActivityIndicatorPopup.Create())
{
await GetDataAsync();
}


This will be a description of the tasks of this stage. You will need to complete certain objectives here.


Web Performance, Inc. is a sponsor of Jason Tower’s Spec E30 racing season this year, and he invited me to Virginia International Raceway to check out our logo on his car, and to try my hand at driving on the track in a HPDE (High Perforformance Driver’s Education) event sponsored by the Tarheel Sports Car Club. As you can see above, the logo looks great on his car alongside the logos of several other local tech. companies.
It was then on to part B of the trip, driving my own car on the track with an instructor, the High Performance Driver’s Education which turned out to be a lot more education that I imagined, with several hours of classroom instruction a day. There’s a dozen flags to memorize, emergency procedures to learn, and lots of hand signals to communicate with other drivers that had to be practiced over and over again. And that doesn’t begin to cover how to actually drive the car!
My day consisted of an hour of classroom instruction followed by 20 minutes on the track followed by more classroom instruction, repeated most of the day. The rules were repeated over and over again as when the adrenaline starts flowing in the car your brain goes out the door and you forget everything. Lots of things can go wrong on the track, and the last thing you want is to crash and hurt yourself or someone else. So my colleagues in the Novice run group were lectured, and cajoled, and finally by the end of the first day we managed to go out and pass each other using the right hand signals in the right parts of the course on the correct side of the car.
Once the rules were learned the experience was incredible; you can’t imagine the adrenaline rush from driving as fast as you dare with the chance to spin off the course at any moment. VIR is full of tricky, difficult to navigate turns and elevation changes that leave you flooring the car towards a blind drop off where you can’t see the track and just have to trust there’s more road there. Its difficult, but addicting, and I’m now in the market for a track-tuned sports sedan to get me to work while being safe and fun on track days.
While I was having fun just learning how to drive around a corner, Jason was having his own learning experience, flatting two tires, and figuring out how to shave down his lap times a few percentage points:

For security reasons, the current directory (".") is no longer included by default at the end of the module search path (@INC). This may have widespread implications for the building, testing and installing of modules, and for the execution of scripts. See the section "Removal of the current directory (".") from @INC" for the full details.
"do" now gives a deprecation warning when it fails to load a file which it would have loaded had "." been in @INC.
See "Unescaped literal "{" characters in regular expression patterns are no longer permissible".
These syntaxes are all supported:
<<~EOF; <<~\EOF; <<~'EOF'; <<~"EOF"; <<~`EOF`; <<~ 'EOF'; <<~ "EOF"; <<~ `EOF`;
The "~" modifier will strip, from each line in the here-doc, the same whitespace that appears before the delimiter.
Newlines will be copied as-is, and lines that don't include the proper beginning whitespace will cause perl to croak.
For example:
if (1) { print <<~EOF; Hello there EOF }
prints "Hello there\n" with no leading whitespace.
"%{^CAPTURE}" is equivalent to "%+" (i.e., named captures). Other than being more self-documenting there is no difference between the two forms.
"%{^CAPTURE_ALL}" is equivalent to "%-" (i.e., all named captures). Other than being more self-documenting there is no difference between the two forms.
use experimental 'refaliasing', 'declared_refs'; my \$a = \$b;
See "Assigning to References" in perlref for more details.
For short keys, 16 bytes and under, we use an optimised variant of One At A Time Hard, and for longer keys we use Siphash 1-3. For very long keys this is a big improvement in performance. For shorter keys there is a modest improvement.
Starting with v5.26, "." is always removed by default, not just under tainting. This has major implications for installing modules and executing scripts.
The following new features have been added to help ameliorate these issues.
There is a new Configure option, "default_inc_excludes_dot" (enabled by default) which builds a perl executable without "."; unsetting this option using "-U" reverts perl to the old behaviour. This may fix your path issues but will reintroduce all the security concerns, so don't build a perl executable like this unless you're really confident that such issues are not a concern in your environment.
There is a new environment variable recognised by the perl interpreter. If this variable has the value 1 when the perl interpreter starts up, then "." will be automatically appended to @INC (except under tainting).
This allows you restore the old perl interpreter behaviour on a case-by-case basis. But note that this is intended to be a temporary crutch, and this feature will likely be removed in some future perl version. It is currently set by the "cpan" utility and "Test::Harness" to ease installation of CPAN modules which have not been updated to handle the lack of dot. Once again, don't use this unless you are sure that this will not reintroduce any security concerns.
While it is well-known that "use" and "require" use @INC to search for the file to load, many people don't realise that "do "file"" also searches @INC if the file is a relative path. With the removal of ".", a simple "do "file.pl"" will fail to read in and execute "file.pl" from the current directory. Since this is commonly expected behaviour, a new deprecation warning is now issued whenever "do" fails to load a file which it otherwise would have found if a dot had been in @INC.
Here are some things script and module authors may need to do to make their software work in the new regime.
If the issue is within your own code (rather than within included modules), then you have two main options. Firstly, if you are confident that your script will only be run within a trusted directory (under which you expect to find trusted files and modules), then add "." back into the path; e.g.:
BEGIN { my $dir = "/some/trusted/directory"; chdir $dir or die "Can't chdir to $dir: $!\n"; # safe now push @INC, '.'; } use "Foo::Bar"; # may load /some/trusted/directory/Foo/Bar.pm do "config.pl"; # may load /some/trusted/directory/config.pl
On the other hand, if your script is intended to be run from within untrusted directories (such as /tmp), then your script suddenly failing to load files may be indicative of a security issue. You most likely want to replace any relative paths with full paths; for example,
do "foo_config.pl"
might become
do "$ENV{HOME}/foo_config.pl"
If you are absolutely certain that you want your script to load and execute a file from the current directory, then use a "./" prefix; for example:
do "./foo_config.pl"
If you install a CPAN module using an automatic tool like "cpan", then this tool will itself set the "PERL_USE_UNSAFE_INC" environment variable while building and testing the module, which may be sufficient to install a distribution which hasn't been updated to be dot-aware. If you want to install such a module manually, then you'll need to replace the traditional invocation:
perl Makefile.PL && make && make test && make install
with something like
(export PERL_USE_UNSAFE_INC=1; \ perl Makefile.PL && make && make test && make install)
Note that this only helps build and install an unfixed module. It's possible for the tests to pass (since they were run under "PERL_USE_UNSAFE_INC=1"), but for the module itself to fail to perform correctly in production. In this case, you may have to temporarily modify your script until a fixed version of the module is released. For example:
use Foo::Bar; { local @INC = (@INC, '.'); # assuming read_config() needs '.' in @INC $config = Foo::Bar->read_config(); }
This is only rarely expected to be necessary. Again, if doing this, assess the resultant risks first.
If you maintain a CPAN distribution, it may need updating to run in a dotless environment. Although "cpan" and other such tools will currently set the "PERL_USE_UNSAFE_INC" during module build, this is a temporary workaround for the set of modules which rely on "." being in @INC for installation and testing, and this may mask deeper issues. It could result in a module which passes tests and installs, but which fails at run time.
During build, test, and install, it will normally be the case that any perl processes will be executing directly within the root directory of the untarred distribution, or a known subdirectory of that, such as t/. It may well be that Makefile.PL or t/foo.t will attempt to include local modules and configuration files using their direct relative filenames, which will now fail.
However, as described above, automatic tools like cpan will (for now) set the "PERL_USE_UNSAFE_INC" environment variable, which introduces dot during a build.
This makes it likely that your existing build and test code will work, but this may mask issues with your code which only manifest when used after install. It is prudent to try and run your build process with that variable explicitly disabled:
(export PERL_USE_UNSAFE_INC=0; \ perl Makefile.PL && make && make test && make install)
This is more likely to show up any potential problems with your module's build process, or even with the module itself. Fixing such issues will ensure both that your module can again be installed manually, and that it will still build once the "PERL_USE_UNSAFE_INC" crutch goes away.
When fixing issues in tests due to the removal of dot from @INC, reinsertion of dot into @INC should be performed with caution, for this too may suppress real errors in your runtime code. You are encouraged wherever possible to apply the aforementioned approaches with explicit absolute/relative paths, or to relocate your needed files into a subdirectory and insert that subdirectory into @INC instead.
If your runtime code has problems under the dotless @INC, then the comments above on how to fix for script authors will mostly apply here too. Bear in mind though that it is considered bad form for a module to globally add a dot to @INC, since it introduces both a security risk and hides issues of accidentally requiring dot in @INC, as explained above.
If perl performed output at a point where it hadn't yet parsed its switches this could result in perl creating or overwriting the file named by "PERLIO_DEBUG" even when the "-T" switch had been supplied.
Perl now requires the "-Di" switch to be present before it will produce PerlIO debugging output. By default this is written to "stderr", but can optionally be redirected to a file by setting the "PERLIO_DEBUG" environment variable.
If perl is running setuid or the "-T" switch was supplied, "PERLIO_DEBUG" is ignored and the debugging output is sent to "stderr" as for any other "-D" switch.
These have been deprecated since v5.16, with a deprecation message raised for some uses starting in v5.22. Unfortunately, the code added to raise the message was buggy and failed to warn in some cases where it should have. Therefore, enforcement of this ban for these cases is deferred until Perl 5.30, but the code has been fixed to raise a default-on deprecation message for them in the meantime.
Some uses of literal "{" occur in contexts where we do not foresee the meaning ever being anything but the literal, such as the very first character in the pattern, or after a "|" meaning alternation. Thus
qr/{fee|{fie/
matches either of the strings "{fee" or "{fie". To avoid forcing unnecessary code changes, these uses do not need to be escaped, and no warning is raised about them, and there are no current plans to change this.
But it is always correct to escape "{", and the simple rule to remember is to always do so.
See Unescaped left brace in regex is illegal here.
A form of backward compatibility is provided via "Hash::Util::bucket_ratio()" which provides the same behavior as "scalar(%hash)" provided in Perl 5.24 and earlier.
sub foo : lvalue { keys(%INC) } (foo) = 3; # death sub bar : lvalue { keys(@_) } (bar) = 3; # also an error
This makes the lvalue sub case consistent with "(keys %hash) = ..." and "(keys @_) = ...", which are also errors. [perl #128187] <https://rt.perl.org/Public/Bug/Display.html?id=128187>
if (!%h) { ... }
This was already special-cased, but some cases were missed (such as "grep %$_, @AoH"), and even the ones which weren't have been improved.
We use a different hash function for short and long keys. This should improve performance and security, especially for long keys.
Reading from a file line-by-line with "readline()" or "<>" should now typically be faster due to a better implementation of the code that searches for the next newline character.
my @a; for my $i (1..10_000_000) { @a = (1,2,3); @a = (); }
my @a = split ...; local @a = split ...;
This also means that void-context warnings on constant expressions of barewords now report the folded constant operand, rather than the operation; this matches the behaviour for non-bareword constants.
The deprecation message for the ":unique" and ":locked" attributes now mention that they will disappear in Perl 5.28.
Its output is now more descriptive for "op_private" flags.
It now uses 3-arg "open()" instead of 2-arg "open()". [perl #130122] <https://rt.perl.org/Public/Bug/Display.html?id=130122>
The XS implementation now supports Deparse.

It no longer treats "no MyFilter" immediately following "use MyFilter" as end-of-file. [perl #107726] <https://rt.perl.org/Public/Bug/Display.html?id=107726>
Internal 599-series errors now include the redirect history.

It now uses 3-arg "open()" instead of 2-arg "open()". [perl #130122] <https://rt.perl.org/Public/Bug/Display.html?id=130122>
IPv6 addresses and "AF_INET6" sockets are now supported, along with several other enhancements.
It now uses 3-arg "open()" instead of 2-arg "open()". [perl #130122] <https://rt.perl.org/Public/Bug/Display.html?id=130122>
Its compilation speed has been improved slightly.
It now ignores /dev/tty on non-Unix systems. [perl #113960] <https://rt.perl.org/Public/Bug/Display.html?id=113960>
This remedies several defects in making its symbols exportable. [perl #127821] <https://rt.perl.org/Public/Bug/Display.html?id=127821>
The "POSIX::tmpnam()" interface has been removed, see "POSIX::tmpnam() has been removed".
The following deprecated functions have been removed:
POSIX::isalnum POSIX::isalpha POSIX::iscntrl POSIX::isdigit POSIX::isgraph POSIX::islower POSIX::isprint POSIX::ispunct POSIX::isspace POSIX::isupper POSIX::isxdigit POSIX::tolower POSIX::toupper
Trying to import POSIX subs that have no real implementations (like "POSIX::atend()") now fails at import time, instead of waiting until runtime.
This adds support for the new "/xx" regular expression pattern modifier, and a change to the "use re 'strict'" experimental feature. When "re 'strict'" is enabled, a warning now will be generated for all unescaped uses of the two characters "}" and "]" in regular expression patterns (outside bracketed character classes) that are taken literally. This brings them more in line with the ")" character which is always a metacharacter unless escaped. Being a metacharacter only sometimes, depending on an action at a distance, can lead to silently having the pattern mean something quite different than was intended, which the "re 'strict'" mode is intended to minimize.
Fixes [perl #130098] <https://rt.perl.org/Public/Bug/Display.html?id=130098>.

This file documents all upcoming deprecations, and some of the deprecations which already have been removed. The purpose of this documentation is two-fold: document what will disappear, and by which version, and serve as a guide for people dealing with code which has features that no longer work after an upgrade of their perl.
Additionally, all references to Usenet have been removed, and the following selected changes have been made:
perlfunc
perlguts
perlhack
perlhacktips
perlinterp

perlmod
perlmodlib
perlobj
perlootut

(A) You've accidentally run your script through bash or another shell instead of Perl. Check the "#!" line, or manually feed your script into Perl yourself. The "#!" line at the top of your file could look like:
#!/usr/bin/perl
(A) You've accidentally run your script through zsh or another shell instead of Perl. Check the "#!" line, or manually feed your script into Perl yourself. The "#!" line at the top of your file could look like:
#!/usr/bin/perl
(F) To declare references to variables, as in "my \%x", you must first enable the feature:
no warnings "experimental::declared_refs"; use feature "declared_refs";
See "Declaring a reference to a variable".
Using the empty pattern (which re-executes the last successfully-matched pattern) inside a code block in another regex, as in "/(?{ s!!new! })/", has always previously yielded a segfault. It now produces this error.
Unescaped left braces are now illegal in some contexts in regular expression patterns. In other contexts, they are still just deprecated; they will be illegal in Perl 5.30.
(F) The parser found a line starting with "<<<<<<<", ">>>>>>>", or "=======". These may be left by a version control system to mark conflicts after a failed merge operation.
New Warnings
(S experimental::declared_refs) This warning is emitted if you use a reference constructor on the right-hand side of "my()", "state()", "our()", or "local()". Simply suppress the warning if you want to use the feature, but know that in doing so you are taking the risk of using an experimental feature which may change or be removed in a future Perl version:
no warnings "experimental::declared_refs"; use feature "declared_refs"; $fooref = my \$foo;
See "Declaring a reference to a variable".
Since "." is now removed from @INC by default, "do" will now trigger a warning recommending to fix the "do" statement.

This install warning is more or less obsolete, since most platforms already will have a /usr/bin/perl or similar provided by the OS.
Previously, two progress messages were emitted for each manpage: one by installman itself, and one by the function in install_lib.pl that it calls to actually install the file. Disabling the second of those in each case saves over 750 lines of unhelpful output.
This version of VC++ includes a completely rewritten C run-time library, some of the changes in which mean that work done to resolve a socket "close()" bug in perl #120091 and perl #118059 is not workable in its current state with this version of VC++. Therefore, we have effectively reverted that bug fix for VS2015 onwards on the basis that being able to build with VS2015 onwards is more important than keeping the bug fix. We may revisit this in the future to attempt to fix the bug again in a way that is compatible with VS2015.
These changes do not affect compilation with GCC or with Visual Studio versions up to and including VS2013, i.e., the bug fix is retained (unchanged) for those compilers.
Note that you may experience compatibility problems if you mix a perl built with GCC or VS <= VS2013 with XS modules built with VS2015, or if you mix a perl built with VS2015 with XS modules built with GCC or VS <= VS2013. Some incompatibility may arise because of the bug fix that has been reverted for VS2015 builds of perl, but there may well be incompatibility anyway because of the rewritten CRT in VS2015 (e.g., see discussion at <http://stackoverflow.com/questions/30412951>).

Calling them, while passing a string length of 0 is now asserted against in DEBUGGING builds, and otherwise, returns the Unicode REPLACEMENT CHARACTER. If you have nothing to decode, you shouldn't call the decode function.
They now return the Unicode REPLACEMENT CHARACTER if called with UTF-8 that has the overlong malformation and that malformation is allowed by the input parameters. This malformation is where the UTF-8 looks valid syntactically, but there is a shorter sequence that yields the same code point. This has been forbidden since Unicode version 3.1.
They now accept an input flag to allow the overflow malformation. This malformation is when the UTF-8 may be syntactically valid, but the code point it represents is not capable of being represented in the word length on the platform. What "allowed" means, in this case, is that the function doesn't return an error, and it advances the parse pointer to beyond the UTF-8 in question, but it returns the Unicode REPLACEMENT CHARACTER as the value of the code point (since the real value is not representable).
They no longer abandon searching for other malformations when the first one is encountered. A call to one of these functions thus can generate multiple diagnostics, instead of just one.

Formerly the first child of a split would be a "pushre", which would have the "split"'s regex attached to it. Now the regex is attached directly to the "split" op, and the "pushre" has been eliminated.

It is with great sadness that we also note Kip Hampton's passing. Probably best known as the author of the Perl & XML column on XML.com, he was a core contributor to AxKit, an XML server platform that became an Apache Foundation project. He was a frequent speaker in the early days at OSCON, and most recently at YAPC::NA in Madison. He was frequently on irc.perl.org as ubu, generally in the #axkit-dahut community, the group responsible for YAPC::NA Asheville in 2011.
Kip and his constant contributions to the community will be greatly missed.
Excluding auto-generated files, documentation and release tools, there were approximately 230,000 lines of changes to 1,800 .pm, .t, .c and .h files.

Configure settings related to the management interface, review the last configuration changes and manage extensions to the management console.
View and modify settings for the http and native management interfaces such as a list of allowed origins, security realm, SSL context.
View and manage extensions to the management console. Extensions are a way to add new features to the management console. They're written in JavaScript and fall into two categories:


{% extends "froide_payment/payment/base.html" %} {% load i18n %} {% block payment_method %} {% include "bootstrap_field.html" with field=form.owner_name %} {% include "bootstrap_field.html" with field=form.iban %} {% include "bootstrap_field.html" with field=form.terms %}


These are non-primitive data type which are composed of one or more one fundamental data type.
These are derived from fundamental data type.
For example: struct, array, slices.
An array is a collection of finite number of homogenous items.
The homogenous means that all the data items of an array must be a same data type.
The array elements are stored in consecutively memory location one after another.
By default, the value of each array element is either 0, nil(string), False/ True(Boolean).
| Keyword | variable name | [no. of elements] | data type | value | ||
|---|---|---|---|---|---|---|
| var | numbers | [5] | int | [5]int{12,23,34,56,70} |
var a[5]int = [5]int{2,3,5,6,7}
Accessing of the array elements- The element in an array identified by their position in the array.
In go positions (index value) of first element is 0
and second element is 1
and third element is 2 and so on.
Each element is referred by array name followed by it`s index value
and enclosed within square brackets.


Did you know that &productName; allows using multiselection while searching in a file (&shortcut:Find;)? All the encountered occurrences of a search string are highlighted, while the selection is in different color. Add the next found occurrence to the selection by pressing &shortcut:SelectNextOccurrence;. Include all the occurrences of a search string in the multiple selection by pressing &shortcut:SelectAllOccurrences;.


A variety of icons are provided with brMaterial. You can acces them by name and can modify their color and size.

Hadoop, formally called Apache Hadoop, is an Apache Software Foundation project and open source software platform for scalable, distributed computing. It provides massive storage for any kind of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs. Hadoop is designed to run on a large number of machines that don’t share any memory or disks. That means you can buy a whole bunch of commodity servers, slap them in a rack, and run the Hadoop software on each one. When you want to load all of your organization’s data into Hadoop, what the software does is bust that data into pieces that it then spreads across your different servers. There’s no one place where you go to talk to all of your data; Hadoop keeps track of where the data resides. And because there are multiple copy stores, data stored on a server that goes offline or dies can be automatically replicated from a known good copy. Hadoop is ideal for situations where you want to run analytics that are deep and computationally extensive, like clustering and targeting. It applies to a myriad of markets like finance, online retail, etc. Hadoop 2.x comes with YARN (Yet Another Resource Negotiator) for cluster resource management. Following are the installation steps:
-
Check the ip of the server by running the command:
$ ifconfig
Let’s say the ip looks somewhat like xxx.xxx.xx.xxx
-
Check the hostname provided to the server by running nslookup on the remote machine:
$ nslookup xxx.xxx.xx.xxx
-
SSH to the server from your local machine:
$ ssh<EMAIL_ADDRESS>You should see something like the following after entering credentials: root@Ubuntu-1204-precise-64-minimal ~
-
Edit /etc/hostname :
vim /etc/hostname
-
Change all instances of the current hostname (Ubuntu-1204-precise-64-minimal) to the Hostname provided and save the file. If everything goes well, you should see an entry in /etc/hosts like the one shown below. xxx.xxx.xx.xxx static.xxx.xxx.xx.xxx.clients.your-server.de
If you don’t see such an entry, add it manually.
-
Edit /etc/hosts :
$ vim /etc/hosts
(If its empty just enter machine name)
-
Again change the hostname with $ vim /etc/hostname command
-
Reboot the machine:
$ sudo reboot
-
Download the .tar.gz file of the latest JDK from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.htm lwget –no-cookies –header “Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com” “http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-x64.tar.gz”
UPDATE :
NOTE-1 : The version mentioned here is not the latest version of java. If you want to download the latest version, get the appropriate .tar.gz url. If you want the 7U51 version (used in the document) get the new link from archives page.
NOTE-2 : if the wget command used above doesn’t work, use wget –no-check-certificate –no-cookies –header “Cookie:oraclelicense=accept-securebackup-cookie” instead of wget –no-cookies –header “Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com” on your local machine.
-
Create a folder for the java setup on the remote machine:
$ mkdir /usr/local/java $ cd /usr/local/java
-
Copy the java setup to remote machine by running the following command on your local machine :
$ scp jdk-7u51-linux-x64.tar.gz root@148.xxx.xx.135:/usr/local/java/
-
Run the following command (replace jdk-7u51 with the corresponding version name) on the remote machine:
$ cd /usr/local/java $ sudo tar -xvzf jdk-7u51-linux-x64.tar.gz
-
Check the name of the extracted folder (marked in bold, this may differ for you, and you need to use that particular name in the steps that follow):
root@hadoop-namenode /usr/local/java ls -a . .. jdk1.7.0_51 jdk-7u51-linux-x64.tar.gz
-
(Optional) At this point, you can remove the .tar.gz file
rm jdk-7u51-linux-x64.tar.gz
-
$ vim /etc/profile
-
Add the following lines at the end of the file, and save the file (Esc :wq):
JAVA_HOME=/usr/local/java/jdk1.7.0_51 PATH=$PATH:$HOME/bin:$JAVA_HOME/bin export JAVA_HOME export PATH
-
Inform the system where your Oracle Java JDK is located. This will tell the system that the new Oracle Java version is available for use.
root@hadoop-namenode /usr/local/java sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jdk1.7.0_79/bin/java" 1
root@hadoop-namenode /usr/local/java sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.7.0_51/bin/javac" 1
root@hadoop-namenode /usr/local/java sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jdk1.7.0_51/bin/javaws" 1
-
Inform the system that Oracle Java JDK must be the default Java.
root@hadoop-namenode /usr/local/java sudo update-alternatives --set java /usr/local/java/jdk1.7.0_79/bin/java
root@hadoop-namenode /usr/local/java sudo update-alternatives --set javac /usr/local/java/jdk1.7.0_51/bin/javac
root@hadoop-namenode /usr/local/java sudo update-alternatives --set javaws /usr/local/java/jdk1.7.0_51/bin/javaws
-
Reload your system wide PATH /etc/profile :
root@hadoop-namenode /usr/local/java . /etc/profile
-
Check that java was installed correctly:
root@hadoop-namenode ~ java -version java version "1.7.0_51" Java(TM) SE Runtime Environment (build 1.7.0_51-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
root@hadoop-namenode ~ javac -version javac 1.7.0_51
-
Install NTP (if not already installed):
root@hadoop-namenode ~ apt-get install ntp
-
sudo /etc/init.d/ntp reload
-
Disable SELinux:
apt-get install selinux-utils getenforce
If result is disabled or permissive, no further action is required. Otherwise
setenforce 0
-
Disable IPTables:
service ufw stop
-
Install requirements:
sudo apt-get install rpm sudo apt-get install curl
-

-
ONLY on the namenode, format and start the namenode
su $HDFS_USER hdfs namenode -format
/usr/lib/hadoop/sbin/hadoop-daemon.sh --config /etc/hadoop/conf start namenode
If the above commands execute properly, then the namenode setup is working. When namenode is running, see : http://static.136.xx.xxx.148.clients.your-server.de:50070/
-
Execute these commands on the SecondaryNameNode:
su $HDFS_USER
/usr/lib/hadoop/sbin/hadoop-daemon.sh --config /etc/hadoop/conf start secondarynamenode
-
Execute these commands on all DataNodes:
su $HDFS_USER
/usr/lib/hadoop/sbin/hadoop-daemon.sh --config /etc/hadoop/conf start datanode
-
Create hdfs user directory in HDFS:
su $HDFS_USER hadoop fs -mkdir -p /user/hdfs
Try copying a file into HDFS and listing that file:
su $HDFS_USER hadoop fs -copyFromLocal /etc/passwd passwd hadoop fs -ls
If you see the file listed, then it has been created properly.
-
Start YARN Execute these commands from the ResourceManager server:
su $YARN_USER export HADOOP_LIBEXEC_DIR=/usr/lib/hadoop/libexec
/usr/lib/hadoop-yarn/sbin/yarn-daemon.sh --config /etc/hadoop/conf start resourcemanager
Execute these commands from all NodeManager nodes:
su $YARN_USER export HADOOP_LIBEXEC_DIR=/usr/lib/hadoop/libexec
/usr/lib/hadoop-yarn/sbin/yarn-daemon.sh --config /etc/hadoop/conf start nodemanager
-
Start MapReduce JobHistory Server (on the namenode): We need to do this step on data-nodes before starting node manager, else it shows error on health check and shows unhealthy nodes.
chown -R root:hadoop /usr/lib/hadoop-yarn/bin/container-executor chmod -R 6050 /usr/lib/hadoop-yarn/bin/container-executor $ su hdfs $ hadoop fs -mkdir -p /mr-history/tmp $ hadoop fs -chmod -R 1777 /mr-history/tmp $ hadoop fs -mkdir -p /mr-history/done $ hadoop fs -chmod -R 1777 /mr-history/done $ hadoop fs -chown -R mapred:hdfs /mr-history $ hadoop fs -mkdir -p /app-logs $ hadoop fs -chmod -R 1777 /app-logs $ hadoop fs -chown yarn /app-logs $ exit $ su mapred $ export HADOOP_LIBEXEC_DIR=/usr/lib/hadoop/libexec/ $ /usr/lib/hadoop-mapreduce/sbin/mr-jobhistory-daemon.sh --config /etc/hadoop/conf start historyserver
-
