Hello,
This patch simplifies how the environment is created and passed around
the functions that create front ends. With this change, the
environment can simply be allocated on the stack and passed by
reference to the libabigail pipeline.
At the core of this change, type_or_decl_base::priv now carries a
const reference to an environment rather than a pointer. The side
effect is that type_or_decl_base can no longer be copied. This is not
a problem because throughout the years I could see that the use case
to copy ABI artifacts is just not there. Similarly, elf_symbol::priv
carries a const reference to environment now, no more a pointer.
Getters, setters and code that use the environment from the ABI
artifacts are updated accordingly.
The DWARF front-end can now be created by code that looks like this,
for instance:
vector<char**> debug_info_paths;
abigail::ir::environment env;
abigail::ctf_reader::read_context_sptr reader =
abigail::dwarf_reader::create_read_context("elf/file/to/analyze",
debug_info_paths, env);
elf_reader::status reading_status;
corpus_sptr abi_corpus =
abigail::dwarf_reader::read_corpus_from_elf(reader, reading_status);
/* then do something with the resulting abi_corpus*/
Note how, you don't need to use the "new" operator to instantiate the
"env" object of type environment. It can sit on the stack and it's
passed to the read_corpus_from_elf function by reference.
In other words, the internal representation types have been changed to
refer to the environment by reference, rather than requiring a pointer
to it.

Adjust.
(enum_type_decl::enumerator::priv::env_): Remove this pointer to
env. This is because the enumerator must be copy-able. As the
enumerator doesn't have an env anymore, it can't intern strings.
So the enumerator name and qualified name is not going to be
interned. If that incurs a performance hit, we'll reconsider this
decision. For now, it seems to work OK. As it simplifies things,
I am keeping this for now.

To: gprocida; +Cc: woodard, guillermo.e.martinez, jose.marchesi, dodji, libabigail
Hello,
This patch is a reorganization of the code to better support the need
for having several different front-ends.
In the libabigail pipeline of operation, a front-end is the part of
the pipeline that analyses the input file. For instance, to analyse
an ELF file, there is going to be one front-end. To analyse an ABIXML
file, there is going to be another front-end.
The middle-end is the part of the pipeline that interacts with the
internal representation of ABIs. The middle-end knows how to analyse,
compare ABI corpora provide an internal representation of the
comparison result and analyse it as well.
The back-end would be the part of the front-end that knows how to
serialize internal representations of ABIs and ABI comparison results.
One could thus imagine a front-end that understands the DWARF debug
info format embedded in an ELF file. Another front-end would be
dedicated to the CTF debug info format, and so on.
Front-ends can share capabilities. For instance, DWARF and CTF
front-ends are ELF based front end. As such, they share capabilities
to understand the ELF format. They don't share much with the ABIXML
front-end, however, as it's based on XML, which has almost nothing in
common with ELF.
To support this organization of concepts, this patch introduces a new
hierarchy of types in the form of C++ classes.
All front-ends implements the "Front End Interface". As such, they
all inherit the abigail::fe_iface class.
That class provides properties and behaviours that are shared by all
front-ends that libabigail supports today. Namely, that class
provides access to some of the options that are relevant to operating
the front-end, to the ABI corpus or corpus group being constructed and
to the suppression specifications that are considered. It also
provides an abstract interface to perform the actual loading of the
ABI corpus. That abstract interface has to be implemented by every
single concrete front-end that is provided in libabigail.
Then, there is the "ELF Reader" front-end. Its class name is
abigail::elf::reader. It inherits the abigail::fe_iface class and
implements the fe_iface::load_corpus() so that the ELF properties of
the ELF file be loaded and exposed in the ABI corpus as returned by
the fe_iface::corpus() accessor. This ELF reader front-end also
provides lots of capabilities that are specific to accessing ELF
content.
Then, there is a common base class for ELF-based front-ends to come,
named abigail::elf_based_reader, which inherits the abigail::elf::reader
class. The purpose of this base class is to provide common properties
and behaviours that are necessary to implement things like a DWARF or
a CTF front-end, or any other front-end to support an ELF-based debug
info format.
Then, there is a CTF front-end which class is named
abigail::ctf::reader. It inherits the abigail::elf_based_reader class
and implements the fe_iface::load_corpus() interface to load and
analyse the CTF-specific properties of the ELF file. To do this,
abigail::ctf::reader::load_corpus() re-uses the abigail::elf::load_corpus() member
function to load the generic ELF parts of the ABI corpus. This reader
then constructs the internal representation of the ABI corpus and
passes it to the middle-end for further analysis.
Then, there is a DWARF front-end which class is named
abigail::dwarf::reader. It inherits the abigail::elf_based_reader
class and implements the fe_iface::load_corpus() interface to load and
analyse the DWARF-specific properties of the ELF file. To do this,
abigail::dwarf::reader re-uses the abigail::elf::load_corpus() member
function to load the generic ELF parts of the ABI corpus, just like
what the CTF front-end does. And then, just like the CTF front-end,
this reader then constructs the internal representation of the ABI
corpus and passes it to the middle-end for further analysis.
Lastly, there is an ABIXML front-end which class is named
abigail::abixml::reader. It inherits the abigail::fe_iface class
directly. Note that unlike the two previous front-ends, this one
doesn't inherit the elf_based_reader base class, for reasons that
should be obvious to the astute reader by now. So, this front-end
implements the abigail::fe_iface::load_corpus() abstract interface to
load the properties for the ABI corpus represented in the ABIXML
format, construct the internal representation and pass it to the
middle-end for further analysis.
The code of the tools got adapted to use these front-ends.
The support of CTF is still guarded by #ifdef WITH_CTF pre-processor
macros, but the one cool side effect is that the amount of guarded
code is reduced. Basically, it's only the creation of the CTF
front-end that is guarded. After its creation, what is returned is an
instance of abigail::elf_based_reader::reader, exactly like what is
returned by the creation of a DWARF front-end. Thus, the rest of the
code is exactly the same, regardless of the kind of front-end. I
believe this results in a more elegant and maintainable code.
As a proof-of-concept, this patch also provides the
create_best_elf_based_reader function. This function analyses the ELF
file and depending on the kind of debug info it provides, returns the
right front-end for it. Maybe at some point, all the #ifdef WITH_CTF
guard pre-processing macros will be constrained in a single function
like this one that will take the decision of instantiating the right
front-end. The rest of the code will be as generic as it gets.
The patch adjusts the reference abixml files produced by the CTF
front-end because it now emits the <elf-needed> XML element which was
not emitted before. This is done because the CTF front-end inherits
the elf-reader which reads the "elf-needed" property from the binary,
without explicit intervention from the CTF front-end.
The patch passes 'make distcheck' on all the supported platforms.

(ctf::reader::{elf_handler, elf_fd,
elf_handler_dbg, elf_fd_dbg, symtab, debug_info_root_paths_,
debug_info_root_paths_}): Remove these data members as they are
now properties of the abigail::elf_reader class, which is a parent
class of this abigail::ctf::reader class.

elf_based_reader}.
(ctf::reader::reader): This now delegates to the constructor of
elf_based_reader. It doesn't pass any argument to initialize()
anymore.
(ctf::reader::initialize): Add an overload with no
parameter. In the other overload, do not take a pointer to an
environment as no new environment can be passed to the instance of
reader that is being reset. Adjust the code of the initializer to
reflect all the data members that got removed.

process_ctf_archive, process_ctf_type, lookup_type, read_corpus,

functions that took ctf::read_context as first parameter.
In read_corpus, do not set the corpus::LINUX_KERNEL_BINARY_ORIGIN
origin as that is now done by elf::reader when it reads the
binary.

(process_ctf_type, lookup_type, process_ctf_archive): Remove these
and turn them into member functions of ctf::reader.

these ELF handling functions as ELF handling is now done by the
elf_reader parent class.
(fill_ctf_section): Take a const pointer to Elf_Scn.
(slurp_elf_info, find_ctfa_file): Remove this and make it be a
member of ctf::reader. Also, make it handle only CTF
reader specific pieces. slurp_elf_info now delegates the reading
of generic ELF properties to elf::reader by calling
elf::reader::read_corpus().

the new dwarf::reader rather than to the previous
read_context. Adjust the function body.
(return_comparison_result): Adjust.
(dwarf::reader::reader): Adjust this from
read_context::read_context.
(dwarf::reader::initialize): Adjust from
dwarf::read_context::initialize.
(dwarf::reader::create): New factory static member
function.
(dwarf::reader::~reader): This doesn't have to clear
anything for now.
(dwarf::reader::read_corpus): New virtual member function
which implements the fe_iface::read_corpus pure virtual interface.
This now delegates the reading of the generic ELF properties to
elf::reader by calling elf::reader::read_corpus().
Newer front-ends will be able to do the same.
(dwarf::reader::reset_corpus): New member function.
(dwarf::reader::read_debug_info_into_corpus): Adjust. This
is now a member function. Also, do not set the
corpus::LINUX_KERNEL_BINARY_ORIGIN here as it's now set by the
elf::reader when it loads the binary.

as they got moved into the elf_reader namespace or into the
fe_iface class.

suppression_matches_function_sym_name,
suppression_matches_function_name,

suppr namespace. Make it take an additional parameter that is
reference fe_iface.
(dwarf::reader::load_debug_info): Remove. This became
merged into dwarf::read_debug_info_into_corpus.
(dwarf::{set_debug_info_root_path,
get_debug_info_root_path, get_show_stats, set_drop_undefined_syms,
set_do_log}): Remove.
(add_read_context_suppressions)
(set_read_context_corpus_group, read_corpus_from_elf): Remove.
(read_debug_info_into_corpus): This became a member function of
dwarf::reader.
(create_reader): Renamed create_read_context into this.
Make it return an elf_based_reader_sptr, like the other front-end
factory functions. Adjust.
(reset_dwarf_reader): Renamed reset_read_context into this.
Adjust.
(read_corpus_from_elf): Adjust.
