BREAKING CHANGE

Remove --install-bisector-dbus and the associated infrastructure in
install_base.sh as it is broken. Bisector is not used much anymore, and
its DBus support even less. DBus features also haven't been tested in
years, and given the difficulty of installing the associated libraries
when it was developped, the chances it has bit rotted are extremely
high.

FIX

Give the expected name to the feature so that FtraceCollector knows what
feature to enable when trying to enable a given event.

FIX

Allow trailing whitespaces like \n at the end of the trace_printk
formats that are decoded like events.

FEATURE

FIX

Remove double indirections when manipulating &&dyn CompileEnv.

FEATURE

Allow parsers to return a list of name for each address, rather than a
single name, which corresponds to the reality.

FIX

Ensure the details of the error are shown to the user rather than
abstracting over it with a more generic one.

FIX

Compute symbol size as the difference between the address of the symbol
and the address of the next symbol, rather than the difference between
the address being looked up (which could point in the middle of a
function) and the next symbol.

FIX

Only filter out symbols containing "$" in them, as they are probably arm
mapping symbols that bring nothing when trying to do a symbolic
resolution of an address.

We previously filtered out any symbol that is not an identifier, but
that ended up filtering out symbols created by optimization passes, such
as "getname_flags.part.0", leading to the wrong "putname" function to be
detected.

FIX

Only print the symbolic name of a bitmask if all its set bits are set in
the value, rather than printing it if at least one bit is set.

FIX

Parse %zu, %zd and %zx as a single specifier rather than %z followed by
a character.

FEATURE

Allow C expressions to refer to kallsyms, such as this snippet from
the irq_enable event, where _stext is a symbol (modelled as void *) and
REC->caller_offs a signed integer:

    (void *)((unsigned long)(_stext) + REC->caller_offs)

This is achieved by introducing a ParseEnv::variable_typ() method and
matching EvalEnv::variable_value(), with some modification of the parser
to disambiguate (x)(y)+1 differently depending whether y is a a type or
a variable recognized by ParseEnv::variable_typ().

FEATURE

There is no point in returning an impl IntoIterator, so turn them to
impl Iterator instead.

FIX

Sometimes, multiple symbols share the same address. Rather than simply
taking the last occurence of the address, store all the symbols, so they
can be looked up later rather than appearing as missing.

FIX

When the tkinter Python package is not available, ask users to install
python3-tk rather than the non-existing python3-tkinter.

FIX

Since datetime.utcnow() is deprecated as of Python 3.12, use
datetime.datetime.now() instead as recommended.

Only check the manpage is up to date on Python 3.11 as the format of
argparse help message changed in 3.13. This means the man page must be
updated by running a Python 3.11 install.

Add lisa-load-kmod to the list of commands in the "lisa" man page.

FIX

Python 3.13 inspect.getsource() uses the new __firstlineno__ attribute
that allows getting the first line number of the class declaration.
Unfortunately, this was set to the location inside newtype where the
class is actually created, leading to problems in Sphinx autodoc.

Set the __firstlineno__ attribute manually to the newtype() caller's
location to preseve accurate source location.

FIX

Use the existing YAML.constructor property behavior rather than
instantiating the constructor ourselves. Doing so leads to missing a
loader attribute which breaks loading.

FEATURE

Add "fuse-overlayfs" backend in addition to the existing "overlayfs".
This backend has much better performance than the "copy" backend even if
it is itself worse than the native "overlayfs". However, it can come in
handy in environments that don't allow user namespaces like some modern
distribution (e.g. Ubuntu 24.04 without specific configuration).

FIX

Pass the "mode" parameter to filp_open(). So far it would not have had
any impact as we are never creating new files, but in the future it may
matter.

FIX

Use 250Hz for hardware sampling rate as that value works across all
pixel devices from 6 to 9.

Also make the software sampling rate 1/8 of the hardware sampling rate,
as the hardware only produces a new sample every 8 periods.

FEATURE

Move the feature fully from C to Rust.

* Get the list of feature to enable from module parameter in Rust code.
* Simplify the API of define_feature!() by always requiring
  a FeaturesConfig for parent features.
* Rename ContextExt into ResultExt and add some method.
* Ensure the features visibility is appropriate.

FEATURE

Add parser combinator library to support the pixel6 emeter feature.

FIX

Fix race condition when making an object file copy in extract-binstore function.

FEATURE

Allow &str event fields. In order to achieve that, we need to pass a
struct rust_str to the C code. Unfortunately, a tracepoint parameter
cannot be larger than 64 bits (some generic kernel code requires that).
To workaround that problem, pass all tracepoint parameters by reference.

FIX

* Fix a race condition when dropping WorkItemInner (use
  disable_delayed_work_sync() rather than cancel_delayed_work_sync() and
  use manual synchronization with the work when
  disable_delayed_work_sync() is not available).

* Fix the use of TAIT for rustc <= 1.86

FEATURE

Allow reading and writing files.

FEATURE

* Implement IntoFfi for &str. This is achieved by using struct rust_str
  rather than using const char*, as the latter only allowed a FromFfi
  implementation.

* Pretty print error codes wrapper in ErrorCode. This includes the
  NegativeError type that provides a binding to the PTR_ERR() kernel
  API.

FEATURE

Implement FFI bindings for Result<c_int, NegativeError> to model the
common pattern of C functions returning a positive value, or a negative
error.
