It's missing query string parsing from new URLs, but you can set the
query string programmatically, and it will be part of the URL when
serialized through to_string().
|
|
Completing a relative URL based on a base URL seems like generally
useful functionality.

We were forgetting to adopt the WeakLink, causing a reference leak.
This ended up costing us one allocation per exec(), with this stack:
kmalloc_impl()
Inode::set_vmo()
InodeVMObject::create_with_inode()
Process::do_exec()
Process::exec()
Process::sys$execve()
This was a pain to track down, in the end I caught it by dumping out
every live kmalloc pointer between runs and diffing the sets. Then it
was just a matter of matching the pointer to a call stack and looking
at what went wrong. :^)

I'll be reconstructing parts of the VisualBuilder application here and
then we can retire VisualBuilder entirely once all the functionality
is available in HackStudio.

This removes an item from the vector and returns it.
|
|
Since NonnullRefPtr and NonnullOwnPtr cannot be null, it is pointless
to convert them to a bool, since it would always be true.
This patch makes it an error to null-check one of these pointers.

This is a hack to avoid failing AK unit tests because it didn't even
try to rebuild.
|
|
Whatever this was supposed to be, it was ironically... not implemented.
|
|
Let's arrange things like this instead. It didn't feel right for all of
the ELF handling code to live in AK.
|
|
This didn't end up getting used, so let's get rid of it.
|
|
It's too dang frustrating that we actually crash whenever we hit some
unimplemented printf specifier. Let's just log the whole format string
and carry on as best we can.
|

This returns a const T& for the first element in the queue, without
dequeuing it.
|
|
I got a warning when using '%Q' since that's non-standard. This patch
makes our printf family accept '%llu'.
|
|
Add dedicated internal types for Int64 and UnsignedInt64. This makes it
a bit more straightforward to work with 64-bit numbers (instead of just
implicitly storing them as doubles.)
|
|
This is just a wrapper around strstr() for now. There are many better
ways to search for a string within a string, but I'm just adding a nice
API at the moment. :^)
|
|
This is helpful for anyone who knows up-front how many items are gonna
be appended to the JsonArray.
|
|
Previously we would not run destructors for items in a CircularQueue,
which would lead to memory leaks.
This patch fixes that, and also adds a basic unit test for the class.

http:// URLs no longer include ":80" when serialized, since port 80 is
implied by the protocol. Non-standard ports are still serialized.

ELFLoader::layout() had a "failed" variable that was never set. This
patch checks the return value of each hook (alloc/map section and tls)
and fails the load if they return null.
I also needed to patch Process so that the alloc_section_hook and
map_section_hook actually return nullptr when allocating a region fails.
Fixes #664 :)

This class inherits from CircularQueue and adds the ability dequeue
from the end of the queue using dequeue_end().
Note that I had to make some of CircularQueue's fields protected to
properly implement dequeue_end.

This allows you to retrieve the length (in bytes) of the codepoint the
iterator is currently pointing at.

Use gcc built-in atomics
|
|
|
|
This kind of thing is a bit annoying. On Serenity, size_t is the same
size as u32, but not the same type. Because of "long" or whatever.
This patch makes String not complain about duplicate overloads.
|
|
Also add some setters since this class was very setter-less.
|
|
I don't love this, but I also don't love the Bitmap class in general.

We had two ways to get the data inside a ByteBuffer. That was silly.
|
|
Sometimes you want to trim a byte or two off the end.
|
|
The former allows you to inspect the string while it's being built.
It's an explicit method rather than `operator StringView()` because
you must remember you can only look at it in between modifications;
appending to the StringBuilder invalidates the StringView.
The latter lets you clear the state of a StringBuilder explicitly, to
start from an empty string again.

This simplifies the ownership model and makes Region easier to reason
about. Userspace Regions are now primarily kept by Process::m_regions.
Kernel Regions are kept in various OwnPtr<Regions>'s.
Regions now only ever get unmapped when they are destroyed.

This reverts commit 26e81ad574d463faee19f5973108f80d0e02aaf6.
We forgot to consider UTF-8 here. String is UTF-8 and we need to be
careful about things like this.
|

`AK::String` can now be reversed via AK::String::reverse(). This makes
life a lot easier for functions like `itoa()`, where the output
ends up being backwards. Very much not like the normal STL
(which requires an `std::reverse` object) way of doing things.
A call to reverse returns a new `AK::String` so as to not upset any
of the possible references to the same `StringImpl` shared between
Strings.

This fixes the goofy issue with %p coming out as " 0x123" instead
of "0x00000123".
