Let's catch ourselves if we ever index out of bounds into one of these.

These warnings are pretty harmless, but warnings nonetheless.

This was tripping up CObject which interprets timer ID 0 as "no timer".
Once we got ID 0 assigned, it was impossible to turn it off and it
would fire on every event loop iteration, causing CPU churn.

This allows u64s to be used in HashMaps.

Allow HOST_CXX to be passed to make which will be the actual host
C++ compiler used, such as 'make HOST_CXX=clang++'.

This always felt out-of-place in LibC.
|
|
For some reason, the default CXXFLAGS and such don't get us the
__cxa_demangle symbol in userland.

This variant of get() returns a const JsonValue* instead of a JsonValue
and can be used when you want to peek into a JsonObject's member fields
without making copies.

The mechanism that caches the most recently seen string for each first
character was indexing into the cache using a 'char' subscript. Oops!

Lock each directory before entering it so when using -j, the same
dependency isn't built more than once at a time.
This doesn't get full -j parallelism though, since one make child
will be sitting idle waiting for flock to receive its lock and
continue making (which should then do nothing since it will have
been built already). Unfortunately there's not much that can be
done to fix that since it can't proceed until its dependency is
built by another make process.

This template allows you to define static globals without having them
destroyed on exit.

Little typo here. Don't think many people use this iterator :)

Let's simplify things. There is now only KERNEL.
To see if you're on Serenity, check if __serenity__ is defined.

Allow everything to be built from the top level directory with just
'make', cleaned with 'make clean', and installed with 'make
install'. Also support these in any particular subdirectory.
Specifying 'make VERBOSE=1' will print each ld/g++/etc. command as
it runs.
Kernel and early host tools (IPCCompiler, etc.) are built as
object.host.o so that they don't conflict with other things built
with the cross-compiler.

Using int was a mistake. This patch changes String, StringImpl,
StringView and StringBuilder to use size_t instead of int for lengths.
Obviously a lot of code needs to change as a result of this.
|
|
This has been an annoyingly missing feature for some time.
|

This patch reduces the O(n) tab completion to something like O(log(n)).
The cache is just a sorted vector of strings and we binary search it to
get a string matching our input, and then check the surrounding strings
to see if we need to remove any characters. Also we no longer stat each
file every time.
Also added an #include in BinarySearch since it was using size_t. Oops.
If `export` is called, we recache. Need to implement the `hash` builtin
for when an executable has been added to a directory in PATH.

This is a special specifier that does not output anything to the stream,
but saves the number of already output chars to the provided pointer.
This is apparently used by GNU Nano.
|
|
|
|
Also make it possible to remove() with a value-type Iterator.

binary_search takes a haystack, a size, a needle and a compare function.
The compare function should return negative if a < b, positive if a > b
and 0 if a == b. The "sane default" compare function is integral_compare
which implements this with subtraction a - b.
binary_search returns a pointer to a matching element, NOT necessarily
the FIRST matching element. It returns a nullptr if the element was not
found.
This patch includes tests for binary_search.

Previously, MDDocument only split on Unix-style line endings. This adds
a new function to StringView which handles LF, CR and CRLF.

I broke this while implementing module linking. Also move the actual
demangling work to AK, in AK::demangle(const char*)
|

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.
