The test suite includes a few basic tests and a very crude regression
test, which just concatenates the to_string() of all tokens and checks
the String's hash to be equal. This relies on the format of
HTMLToken::to_string() to stay the same, which is not ideal.
Since Clang enables a couple of warnings that we don't have in GCC,
these were not caught before. Included fixes:
- Use correct printf format string for `size_t`
- Don't compare Nonnull(Ref|Own)Ptr` to nullptr
- Fix unsigned int& => unsigned long& conversion
This test exposed a kernel panic in is_user_range calculations, so let's
convert it to be a LibTest test so we can prevent regressions in mmap,
the page allocator, and the memory manager.
Let's bring this class back, but without the confusing resize() API.
A FixedArray<T> is simply a fixed-size array of T.
The size is provided at run-time, unlike Array<T> where the size is
provided at compile-time.
This patch introduces the SQLServer system server. This service is
supposed to be the only process/application talking to database storage.
This makes things like locking and caching more reliable, easier to
implement, and more efficient.
In LibSQL we added a client component that does the ugly IPC nitty-
gritty for you. All that's needed is setting a number of event handler
lambdas and you can connect to databases and execute statements on them.
Applications that wish to use this SQLClient class obviously need to
link LibSQL and LibIPC.
The Order enum is used in the Meta component of LibSQL. Using this enum
meant having to include the monster AST/AST.h include file. Furthermore,
they are sort of basic and therefore can live in the general SQL
namespace. Moved to LibSQL/Type.h.
Also introduced a new class, SQLResult, which is needed in future
patches.
Now that the test is converted to be LibTest based, we can remove it
from the exclude list in /home/anon/.config/Tests.ini.
Prior to this it would crash and fail because it was signaled instead of
returning normally with exit code 0.
After the changes to LibGfx to make default font management handled in
WindowServer instead of each GUI application to allow for global font
broadcasts, the two LibGfx tests broke. The non-benchmark was fixed in
8f96d2, but the benchmark was left in the dust because nobody really
runs it manually :^(
These are usually incorrect, and people sometimes forget to add the
correct values as a result of them being optional, so they should just
be specified explicitly.
This adds a test case for String::find and String::find_all with empty
needles. The expected behavior is in line with what the C++ standard
library (and other languages standard libraries) expect.
This implements StringUtils::find_any_of() and uses it in
String::find_any_of() and StringView::find_any_of(). All uses of
find_{first,last}_of have been replaced with find_any_of(), find() or
find_last(). find_{first,last}_of have subsequently been removed.
This removes StringView::find_first_of(char) and find_last_of(char) and
replaces all its usages with find and find_last respectively. This is
because those two methods are functionally equivalent.
find_{first,last}_of should only be used if searching for multiple
different characters, which is never the case with the char argument.
This also adds the [[nodiscard]] to the remaining find_{first,last}_of
methods.
This replaces the current LexicalPath::append() API with a new method
that returns a new LexicalPath object and doesn't touch the this-object.
With this, LexicalPath is now immutable. It also adds a
LexicalPath::parent() method and the relevant test cases.
Since this is always set to true on the non-default constructor and
subsequently never modified, it is somewhat pointless. Furthermore,
there are arguably no invalid relative paths.
Split out the functionality to gather multiple tests from the filesystem
and run them in turn into Test::TestRunner, and leave the JavaScript
specific test harness logic in Test::JS::TestRunner and friends.
If someone runs the test with shell redirection going on, or in a way
that changes any of the standard file descriptors this assumption will
not hold. When running from a terminal normally, it is true however.
Instead, check that /proc/self/fd/[0,1,2] are symlinks, and can be
stat-d by verifying that both stat and lstat succeed, and give different
struct stat contents.
Also add some tests to ensure that they _remain_ constexpr.
In general, any runtime assertions, weirdo C casts, pointer aliasing,
and such shenanigans should be gated behind the (helpfully newly added)
AK::is_constant_evaluated() function when the intention is to write
constexpr-capable code.
a.k.a. deliver promises of constexpr-ness :P
This commit converts naked `new`s to `AK::try_make` and `AK::try_create`
wherever possible. If the called constructor is private, this can not be
done, so we instead now use the standard-defined and compiler-agnostic
`new (nothrow)`.
Scanning tables is a linear process using pointers in the table's
tuples, and does not involve more 'stochastic' code paths like index
traversals. Therefore the 1000 and 10000 row tests were basically
overkill and added nothing we can't find out with less rows.
This declares all test cases which compare function outputs over the
entire Unicode range as `BENCHMARK_CASE`, to avoid them being run by CI.
This reduces runtime of TestCharacterTypes (without benchmarks) by about
one third.
SQL was standardized before there was consensus on sane language syntax
constructs had evolved. The language is mostly case-insensitive, with
unquoted text converted to upper case. Identifiers can include lower
case characters and other 'special' characters by enclosing the
identifier with double quotes. A double quote is escaped by doubling it.
Likewise, a single quote in a literal string is escaped by doubling it.
All this means that the strategy used in the lexer, where a token's
value is a StringView 'window' on the source string, does not work,
because the value needs to be massaged before being handed to the
parser. Therefore a token now has a String containing its value. Given
the limited lifetime of a token, this is acceptable overhead.
Not doing this means that for example quote removal and double quote
escaping would need to be done in the parser or in AST node
construction, which would spread lexing basically all over the place.
Which would be suboptimal.
There was some impact on the sql utility and SyntaxHighlighter component
which was addressed by storing the token's end position together with
the start position in order to properly highlight it.
Finally, reviewing the tests for parsing numeric literals revealed an
inconsistency in which tokens we accept or reject: `1a` is accepted but
`1e` is rejected. Related to this is the fate of `0x`. Added a FIXME
reminding us to address this.
