The mentioned functions used m_size / 8 instead of size_in_bytes()
(division with ceiling rounding mode), which resulted in an off-by-one
error such that the functions didn't search in the last not-fully-8-bits
byte.
Using size_in_bytes() instead of m_size / 8 fixes this.
When working with FixedMemoryStreams, and especially MappedFiles, you
may don't want to copy the underlying data when you read from the
stream. Pointing into that data is perfectly fine as long as you know
the lifetime of it is long enough.
This commit adds a couple of methods for reading either a single value,
or a span of them, in this way. As noted, for single values you sadly
get a raw pointer instead of a reference, but that's the only option
right now.
Previously, the first match index was not checked to see if the camel
case or separator bonuses applied. The camel case bonus could also be
incorrectly applied where strings had non-alphabetical characters.
SipHash is highly HashDoS-resistent, initialized with a random seed at
startup (i.e. non-deterministic) and usable for security-critical use
cases with large enough parameters. We just use it because it's
reasonably secure with parameters 1-3 while having excellent properties
and not being significantly slower than before.
Instead of ballooning the size of the Function object, simply place the
callable on the heap with a properly aligned address.
This brings the alignment of Function down from ridiculous sizes like 64
bytes down to a manageable 8 bytes.
…kernel"
This reverts commit d4d92184b3.
The alignemnt requirements imposed by this are overkill at best and
ridiculous at worst, a future commit will tackle this problem in a
different, more space-efficient way.
This commit also reverts db5ad0c since code outside of the web spec
expects serialized paths to be percent decoded.
Also, there are issues trying to implement the concept "opaque
path". For now, we still use the old cannot_be_a_base_url(), but its
usage needs to be removed in favor of a has_opaque_path() as the spec
has changed since then.
...requested size"
This reverts commit 13573a6c4b.
Some clients of `BufferedStream` expect a non-blocking read by
`read_some` which the commit above made impossible by potentially
performing a blocking read. For example, the following command hangs:
pro http://ipecho.net/plain
This is caused by the HTTP job expecting to read the body of the
response which is included in the active buffer, but since the buffered
data size is less than the buffer passed into `read_some`, another
blocking read is performed before anything is returned.
By reverting this commit, all tests still pass and `pro` no longer
hangs. Note that because of another bug related to `stdout` / `stderr`
mixing and the absence of a line ending, there is no output to the
command above except a progress update.
This is defined when building on GNU/Hurd, the GNU operating system with
the Hurd as its kernel (as it was designed originally, before Linux and
GNU/Linux came to be).
Also, define the corresponding part of User-Agent.
This is defined when we're compiling against the GNU C Library, whether
on Linux or on other kernels that glibc works on. More AK_LIBC_xxxx
definitions could be potentially added in the future.
Also add AK_LIBC_GLIBC_PREREQ(), which checks for a specific glibc
version.
While macOS backtrace(3) puts a space directly after the mangled symbol
name, some versions of glibc put a + directly after it. This new logic
accounts for both situations when trying to demangle.

On platforms that support it, enable using ``<execinfo.h>`` to get
backtrace(3) to dump a backtrace on assertion failure. This should make
debugging things like WebContent crashes in Lagom much easier.
This part of the spec is mostly useful for our debugging for now, but
could eventually be hooked up so that the user can see any reported
validation errors.
The main change here is that we now follow the spec by asserting the URL
is not special. Previously I could not find a way to enable this without
getting assertions when browsing the web - but that seems to no longer
be the case (probably from some other fixes which have since been made).
