Previously, when trying to debug variables with more complex
types (such as String), we would crash the debugger simply because
it didn't know how to handle types that were irrelevant anyways.
Now we just skip data we don't yet know how to handle.
|
|
|
|
For one, viewing a variable who's type contained a subprogram will
no longer crash HackStudio. Additionally, the variable view will
handle invalid enum values gracefully now, fixing another crash.
Finally, deeply nested (nest count > 1) structures will have their
memory addresses properly set, fixing the final crash I found.
|
|
HackStudio's debugger instance has its source root property updated
when switching projects, and breakpoints will properly canonicalize
their file paths as the Debugger now expects.

GCC determines whether the system's <limits.h> header is usable
and installs a different version of its own <limits.h> header
depending on whether the system header file exists.
If the system header is missing GCC's <limits.h> header does not
include the system header via #include_next.
For this to work we need to install LibC's headers before
attempting to build GCC.
Also, re-running BuildIt.sh "hides" this problem because at that
point the sysroot directory also already has a <limits.h> header
file from the previous build.

The find_last_of implementations were breaking out of the search loop
too early for single-character string views. This caused a crash in
CookieJar setting a cookie on google.com - CookieJar::default_path knew
there was at least one "/" in a string view, but find_last_of returned
nullopt, so dereferencing the optional caused a crash.
Fixes #6273

Setting the year to NumericLimits<unsigned>::max() resulted in the
following datetime: -2-12-31 00:00:00.
Instead, set the latest datetime to the last second of the year 9999.

Using document.cookie only lets the test page see the name/value pair;
the value returned will not included the parsed attributes.

Printing error messages to stdout can have unintended side effects
depending on what the program is doing.
|
|
This way CRASH() can be used in functions that are themselves
marked as noreturn.
|
|
No more top bar, no more extra padding. Spacing is equal on the top and
on the left, so it looks pretty tidy.

This should provide some speed up, as currently searches for regions
containing a given address were performed in O(n) complexity, while
this container allows us to do those in O(logn).
|
|
This does not affect functionality right now, but it means that the
regions vector will now never have any overlapping regions, which will
allow the use of balance binary search trees instead of a vector in the
future. (since they require keys to be exclusive)
|
|
This container is similar to the RedBlackTree container, but instead of
transparently allocating tree nodes on insertion and freeing on removal
this container piggybacks on intrusive node fields in the stored class
|
|
This container is based on a balanced binary search tree, and as such
allows for O(logn) worst-case insertion, removal, and search, as well
as O(n) sorted iteration.

Previous a mallocation was marked as 'reachable' when any other
mallocation or memory region had a pointer to that mallocation. However
there could be the situation that two mallocations have pointers to each
other while still being unreachable from anywhere else. They would be
marked as 'reachable' regardless.
This patch replaces the old way of detemining whether a mallocation is
reachable by analyzing the dependencies of the different mallocations
using a graph-approach. Now mallocations are only reachable if pointed
to by other reachable mallocations or other memory regions.
A nice bonus is that this gets rid of a nested for_each_mallocation, so
the complexity of leak finding becomes linear instead of quadratic.

Corrects punctuation width and erroneous 'Q' width reset. Adjusts
height of double quote and '$'

We were including these markers when computing the sizes of menus,
causing them to get a little too much padding.

- fallback to http with curl when https fails
- add --no-gpg-verification, which will skip gpg signature verification
|
|
These old tar files didn't have magic numbers, so I've also added a checksum
check to TarInputStream::valid()
|
|
serenity's getaddrinfo is a stub, but curl detects it anyway, and uses
it instead of gethostbyname.
|
|
nproc prints the number of processors on the system. Our ports system
uses it.
|
|
- Refactor env to use Core::ArgsParser
- create symlink from /bin/env to /usr/bin/env for compatiability
|
|
install-ports copys the necessary files from Ports/ to /usr/Ports. Also
refactor the compiler and destiation variables from .port_include.sh
into .hosted_defs.sh. .hosted_defs.sh does not exists when ports are
built in serenity

The previous handling of the name and message properties specifically
was breaking websites that created their own error types and relied on
the error prototype working correctly - not assuming an JS::Error this
object, that is.
The way it works now, and it is supposed to work, is:
- Error.prototype.name and Error.prototype.message just have initial
string values and are no longer getters/setters
- When constructing an error with a message, we create a regular
property on the newly created object, so a lookup of the message
property will either get it from the object directly or go though the
prototype chain
- Internal m_name/m_message properties are no longer needed and removed
This makes printing errors slightly more complicated, as we can no
longer rely on the (safe) internal properties, and cannot trust a
property lookup either - get_without_side_effects() is used to solve
this, it's not perfect but something we can revisit later.
I did some refactoring along the way, there was some really old stuff in
there - accessing vm.call_frame().arguments[0] is not something we (have
to) do anymore :^)
Fixes #6245.

Similar to Value::to_string_without_side_effects() this is mostly a
regular object property lookup, but with the guarantee that it will be
side-effect free, i.e. no accessors or native property functions will
be called. This is needed when we want to access user-controlled object
properties for debug logging, for example. The specific use case will be
error objects which will soon no longer have internal name/message
properties, so we need to guarantee that printing an error, which may
already be the result of an exception, won't blow up in our face :^)

This returns the parent frame of the current frame. If it's the
main frame, it returns itself.
Also fixes the attributes of Window.top, as they were accidentally
being passed in as the setter.

Note: the default expiry time should be the "the latest representable
date". However, DateTime::from_timestamp(NumericLimits<time_t>::max())
isn't feasible due to the for-loops in LibC's time_to_tm. So instead,
this just sets the date to the maxium year.

Implements the remainder of the parsing algorithm of RFC-6265 Section
5.2 to extract optional attributes. The attribute values are not
processed.
