This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
This makes it easier to work with device tree nodes and properties, then
writing simple state machines to parse the device tree.
This also makes the old slow traversal methods use the
DeviceTreeProperty helper class, and adds a simple test.
Semantic Versioning (SemVer) is a versioning scheme for software that
uses MAJOR.MINOR.PATCH format. MAJOR for significant, possibly
breaking changes; MINOR for backward-compatible additions; PATCH for
bug fixes. It aids communication, compatibility prediction, and
dependency management. In apps dependent on specific library versions,
SemVer guides parsing and validates compatibility, ensuring apps use
appropriate dependencies.
<valid semver> ::= <version core>
| <version core> "-" <pre-release>
| <version core> "+" <build>
| <version core> "-" <pre-release> "+" <build>
The current helpers assume that a valid URL is a full URL (i.e. contains
the "://" separator between the scheme and domain). This isn't true, as
"file:" alone is parsed as a valid URL.
We must also avoid simply searching for the parsed public suffix in the
original URL string. For example, "com" is a public suffix. If we search
for that in the URL "com.com", we will think the public suffix starts at
index 0.
`i` is used as the index for 'old lines' in diff generation, not 'new
lines'. Using the wrong index would mean that for certain diffs the
prefixed context information would have wrong content, and could even
result in a crash.
Fix this, and add a test for an input which was previously crashing.
While the tests for sed itself are simple to begin with, some
infrastructure was needed to make them simple.
Firstly, there was no home for tests for the applications under
Utilities, so I had to create a new subdirectory under Tests to host
them.
Secondly, and more importantly, there was previously no easy way to
launch an executable and easily feed it with data for its stdin, then
read its stdout/err and exit code. Looking around the repo I found that
the JS tests do a very similar thing though, so I decided to adapt that
solution for these tests, but with the higher purpose of someday moving
this new Process class to LibCore/Process, where the existing spawn
helpers are still very low level, and there is no representation of a
Process object that one can easily interact with.
Note that this Process implementation is very simple, offers limited
functionality, and it doesn't use the EventLoop, so it can break on long
inputs/outputs depending on the executable behavior.
The FLAC "spec tests", or rather the test suite by xiph that exercises
weird FLAC features and edge cases, can be found at
https://github.com/ietf-wg-cellar/flac-test-files and is a good
challenge for our FLAC decoder to become more spec compliant. Running
these tests is similar to LibWasm spec tests, you need to pass
INCLUDE_FLAC_SPEC_TESTS to CMake.
As of integrating these tests, 23 out of 63 fail. :yakplus:
For example, with this input:
```xml
<C>]]>
```
After seeing `<C>`, the parser will start parsing the content of the
element. The content parser will then parse any character data it sees.
The character parser would see the first two `]]` and consume them.
Then, it would see the `>` and set the state machine to say we have
seen this, but it did _not_ consume it and would instead tell
GenericLexer that it should stop consuming characters. Therefore,
we only consumed 2 characters.
Then, it would see that we are in the state where we've seen the
full `]]>` and try to take off three characters from the end of the
consumed input when we only have 2 characters, causing an assertion
failure as we are asking to take off more characters than there really
is.
This library can be used (for the most part) by kernel drivers as well
as user mode. For this reason FixedPoint is used rather than floating
point, but kept to a minimum.
Add a unit test for each sample pdf file that currently exists in the
anon user's `~/Document/pdf` directory.
- linear.pdf
- non-linearized.pdf
- complex.pdf
Each test ensures that the pdf document is parsed and that the page
count is the expected one.
At the moment we just check if we *can* render a simple triangle, we do
not yet actually test if the image is indeed the triangle we wanted.
This test also outputs the rendered image when GL_DEBUG is enabled to a
file called "picture.bmp" for manual verification.

There seems to be more incorrect assumptions about Clang-built
executables' memory layout than expected. These make the CI fail even
though the system is functional in all other aspects. While this is
being fixed, let's just disable tests for UserspaceEmulator.
The Unicode standard publishes the Unicode Character Database (UCD) with
information about every code point, such as each code point's upper case
mapping. LibUnicode exists to download and parse UCD files at build time
and to provide accessors to that data.
As a start, LibUnicode includes upper- and lower-case code point
converters.
This only tests "can it be parsed", but the goal of this commit is to
provide a test framework that can be built upon :)
The conformance tests are downloaded, compiled* and installed only if
the INCLUDE_WASM_SPEC_TESTS cmake option is enabled.
(*) Since we do not yet have a wast parser, the compilation is delegated
to an external tool from binaryen, `wasm-as`, which is required for the
test suite download/install to succeed.
This *does* run the tests in CI, but it currently does not include the
spec conformance tests.
For each .cpp file in the test suite data, there is a .ast file that
represents the "known good" baseline of the parser result.
Each .cpp file goes through the parser, and the result of
invoking `ASTNode::dump()` on the root node is compared to the
baseline to find regressions.
We also check that there were no parser errors when parsing the .cpp
files.
This patch adds some rudimentary tests for InodeWatcher. It tests the
basic functionality, but maybe there are corner cases I haven't caught.
Additionally, this is our first LibCore test. :^)
With the goal of centralizing all tests in the system, this is a
first step to establish a Tests sub-tree. It will contain all of
the unit tests and test harnesses for the various components in the
system.
