Hello,
The core of this patch is to beef up the suppression specification
language so that we can express something like this:
[allow_type] #1
label = first-suppr
type_kind = struct
has_data_member_regexp = ^__reserved_padding #2
[suppress_type]
label = second-suppr
type_kind = struct
has_data_member_inserted_between =
{
offset_of_first_data_member_regexp(^__reserved_padding), #3
offset_of_last_data_member_regexp(^__reserved_padding), #4
}
In #1, the [allow_type] directive suppresses all type changes that do
NOT match this directive. I call this a "negative type suppression
specification". In #2, the "has_data_member_regexp" property matches
a type which has a data member which name matches the regular
expression value of this property.
In #3, the offset_of_first_data_member_regexp() function-like expression
evaluates to the offset of the first data member which name matches
the regular expression in argument.
In #4, the offset_of_last_data_member_regexp() function-like
expression evaluates to the offset of the last data member which name
matches the regular expression in argument.
The patch set not only implements the features #1 to #4 but also
includes some performance work to improve the speed of the analysis of
big binaries with lots diff nodes.
Dodji Seketeli (13):
ini: Fix parsing list property values
suppr: Support has_data_member and has_data_member_regexp properties
suppression: Factorize out is_data_member_offset_in_range
suppression: Support the has_size_change property for suppress_type
suppression: Support offset_of_{first,last}_data_member_regexp offset selectors
comparison, suppression: Support [allow_type] directive
Misc white space fixes
abidiff: Add extensive logging
tools-utils: Support kernel stablelist
comp-filter: Don't re-visit node while applying filters to diff nodes
comparison: Add a mode to not apply filters on interface sub-graphs
comparison: When marking leaf nodes don't do unnecessary impact analysis
comp-filter: Speed up harmless/harmful categorization

Hello,
While looking at something else, I came across an issue in
read_context::read_list_property_value. This function requires
elements of a list property value (separated by a comma) to be on a
single line, for instance. This is because the code forgets to parse
white spaces after the comma.
Fixed thus.
* src/abg-ini.cc (read_context::read_list_property_value): Expect
white spaces after the comma.

Hello,
In the [supress_type] directive, this patch adds support for two new
properties:
* has_data_data_member = {foo, bar, blah}
Suppresses change reports involving a type which has data members
with names specified by the value of this property.
* has_data_member_regexp = some-regexp
Suppresses change reports involving a type which has data members
with names specified by the regular expression given as a value of
this property.
* include/abg-fwd.h (string_set_type): Define new typedef.
* src/abg-suppression-priv.h
* include/abg-suppression.h
(type_suppression::{get,set}_potential_data_member_names[_regex_str]):
Declare new data member.
(type_suppression::priv::{potential_data_members_,
potential_data_members_regex_str_,
potential_data_members_regex_}): Define new data members.
(type_suppression::priv::{get,set}_potential_data_member_names_regex):
Define new member functions.
* src/abg-suppression.cc
(type_suppression::{get,set}_potential_data_member_names): Define new
member functions.
(type_suppression::{get,set}_potential_data_member_names_regex_str):
Likewise.
(type_suppression::suppresses_diff): Implement suppression using
the new "has_data_member" and "has_data_member_regexp" properties.
(read_type_suppression): Support parsing the new "has_data_member"
and "has_data_member_regexp" properties of the type suppression
directive.
* tests/data/test-diff-suppr/has-data-member-[1-7].suppr: New
suppression specifications for test purposes.
* tests/data/test-diff-suppr/test-has-data-member-output-{1,2}.txt:
New reference test outputs.
* tests/data/test-diff-suppr/test-has-data-member-v{0,1}.cc:
Source code of new input binary tests.
* tests/data/test-diff-suppr/test-has-data-member-v{0,1}.o: New
binary test inputs.
* tests/data/Makefile.am: Add the test inputs below to source
distribution.
* tests/test-diff-suppr.cc (in_out_specs): Add the new test inputs
above to this test harness.

Hello,
In preparation of subsequent changes, this patch factorizes a function
is_data_member_offset_in_range() out of
type_suppression::suppression(). This is useful to determine if a
data member offset is within an "offset range" expressed by the
type_suppression::insertion_range type.
This function is useful to implement the
offset_of_first_data_member_regexp and
offset_of_last_data_member_regexp properties to come in subsequent
patches.
Please note that is_data_member_offset_in_range works on data members
of unions and classes, not just on classes like what the original code
of inside type_suppression::suppresses_diff was doing.
This patch should not have any functional impact on the code.
* include/abg-fwd.h (get_last_data_member)
(get_next_data_member_offset): Declare functions.
* src/abg-ir.cc (get_next_data_member): Add an overload for
class_or_union and write the overload for class_or_union_sptr in
term of the former.
(get_last_data_member): Add overloads form class_or_union& and
class_or_union*. Write the overload for class_or_union_sptr in
terms of the one for class_or_union*.
(get_next_data_member_offset): Add an overload for
class_or_union* and write the overload for class_or_union_sptr in
terms of the former.
* include/abg-suppression.h
(type_suppression::insertion_range::eval_boundary): Take a
class_or_union* for the context, as opposed to a class_decl_sptr.
This makes this static function work for unions as well.
(is_data_member_offset_in_range): Declare new function.
* src/abg-suppression.cc (type_suppression::suppression_diff):
Factorize ...
(is_data_member_offset_in_range): ... this function out.
(type_suppression::insertion_range::eval_boundary): Adjust this to
make it take a class_or_union* rather than a class_decl_sptr.

Hello,
The "has_data_member_inserted_between" and
"has_data_members_inserted_between" properties of the [suppress_type]
directive allows the suppression of type changes when a data member is
inserted in a given range. It turns out that suppressing type changes
that incur a change in the size of the type might not be what the user
wants by default, because the type size in itself might actually be an
incompatible ABI change that would then fly under the radar because of
this suppression specification.
An arguably better default behavior in this case would be to NOT
suppress the type change if the data member insertion does incur a
change in the size of the type.
But then, there would be cases where the user would really want to
suppress the type change due to data member insertion in a given range
even if it incurs a change in the type size. This is where this patch
enters into play.
The patch introduces the "has_size_change" property of the
[suppress_type] directive. In the presence of
"has_data_members_inserted_between" or
"has_data_member_inserted_between" properties, if the
"has_size_change" property is set to "yes", then the type change would
be suppressed if data members are inserted in the given range even if
the insertion incurs a type size change.
Otherwise, with this patch, in the absence of the "has_size_change"
property, the "has_data_member_inserted_between" and
"has_data_members_inserted_between" properties won't trigger the type
change suppression if the data member insertion incurs a type size
change.
* doc/manuals/libabigail-concepts.rst: Document the new
has_size_change property.
* include/abg-suppression.h
(type_suppression::{g,s}et_has_size_change): Declare new accessors.

* src/abg-suppression.cc
(type_suppression::{g,s}et_has_size_change): Define new accessors.
(type_suppression::suppresses_diff): Make the
has_data_member_inserted_* clauses have effect only if the class
size hasn't changed, unless the class has as the "has_size_change"
property. Also, allow members to be deleted in the right
insertion range if the resulting size stays the same or if the
has_size_change property is present. This allows some custom
behaviours where "padding" data members would be removed while
some new data members would be added, resulting in a type which
size would not change.
(read_type_suppression): Support parsing the "has_size_change"
property.

From: Dodji Seketeli @ 2023-03-02 18:59 UTC (permalink / raw)
To: Dodji Seketeli; +Cc: libabigail, ckalina
Hello,
This patch adds support for two data member offset selector
expressions for properties of the [suppress_type] directive:
offset_of_first_data_member_regexp() and offset_of_last_data_member_regexp().
These function-call expressions take a regular expression argument and
evaluate to the offset of the first (resp. last) data member matching
the regular expression argument.
An example of their use would be be:
[suppress_type]
type_kind = struct
has_data_member_inserted_between =
{
offset_of_first_data_member_regexp(^__special_padding_space),
offset_of_last_data_member_regexp(^__special_padding_space)
}
This would be useful to suppress change reports involving a struct
which has "padding" data members added on-purpose like:
struct S
{
int member0;
char member1;
unsigned __special_padding_space1;
unsigned __special_padding_space2;
unsigned __special_padding_space3;
};
* doc/manuals/libabigail-concepts.rst: Document the new
properties.
* include/abg-fwd.h: Forward declare comparison::{diff_context,
diff_context_sptr, diff_context_wptr, diff, diff_wptr} and
regex::regex_t_sptr.
(find_first_data_member_matching_regexp)
(find_last_data_member_matching_regexp): Declare new functions.
* include/abg-suppression.h: Inject std::{string, shared_ptr,
vector} and comparison::{diff, diff_context_sptr} into the suppr
namespace. Remove the "abg-comparison.h" header.
* src/abg-elf-helpers.cc: Include sstream.
* src/abg-ir.cc (find_first_data_member_matching_regexp)
(find_last_data_member_matching_regexp): Define new functions.
* src/abg-suppression.cc
(type_suppression::insertion_range::eval_boundary): Support
evaluating "offset_of_first_data_member_regexp" and
"offset_of_first_data_member_regexp".
* src/abg-ctf-reader.cc: Include sstream.
* tests/data/test-diff-suppr/test-has-data-member-inserted-between-1-report-[1-4].txt:
New test reference outputs.
* tests/data/test-diff-suppr/test-has-data-member-inserted-between-1-v[0-4].c:
Source code of new test input.
* tests/data/test-diff-suppr/test-has-data-member-inserted-between-1-v[0-4].o:
New binary test input.
* tests/data/test-diff-suppr/test-has-data-member-inserted-between-1.suppr:
New suppression specification.
* tests/data/Makefile.am: Add the new test input files to source
distribution.
* tests/test-diff-suppr.cc (in_out_specs): Add the new test input
to this test harness.

Hello,
This patch adds support for a new 'allow_type' suppression directive.
It suppresses all the changes that are NOT matched by the directive.
In other words, this directive determines the set of type changes that
are NOT suppressed. Any other change is suppressed. This thus called
a "negated suppression directive".
The way these negated suppression directives interact with the direct
suppression directives that already exist is the following.
The suppression evaluation pass visits every single diff node
(carrying a type change) of the diff graph. Negated suppressions are
evaluated first, in order of occurrence.
There are thus, two alternatives:
1/ At least one negated suppression matches the current diff node.
or
2/ No negated suppression matches the current diff node.
In case of 1/ then direct suppression specifications are
considered. There are two alternatives:
1.1/ At least one direct suppression matches the current diff node.
The diff node is suppressed: categorized as being in the
SUPPRESSED_CATEGORY category)
or
1.2/ No direct suppression matches the current diff node.
The diff node is not suppressed: categorized as being in the
HAS_ALLOWED_CHANGE_CATEGORY category.
In case of 2/ then direct suppression specifications are
considered. There are two alternatives:
2.1 At least one direct suppression matches the current diff node.
The diff node is categorized as being in the
SUPPRESSED_CATEGORY category, just like in 1.1.
2.2 No direct suppression matches the current diff node.
The diff node is not suppressed and not categorized.
As a result of the category propagation pass, a node which has a
parent node categorized as HAS_ALLOWED_CHANGE_CATEGORY is itself
categorized as HAS_PARENT_WITH_ALLOWED_CHANGE_CATEGORY. A node which
has a descendant categorized as HAS_ALLOWED_CHANGE_CATEGORY will
itself be categorized as HAS_DESCENDANT_WITH_ALLOWED_CHANGE_CATEGORY.
Nodes that are categorized as HAS_ALLOWED_CHANGE_CATEGORY,
HAS_DESCENDANT_WITH_ALLOWED_CHANGE_CATEGORY and
HAS_PARENT_WITH_ALLOWED_CHANGE_CATEGORY are not suppressed by the
reporting passes. This is needed for the reporting passes to emit the
impact sub-tree up to the diff node which carry the change that was
actually categorized as HAS_ALLOWED_CHANGE_CATEGORY.

Hello,
While looking at something else I felt the need for having
"abidiff --verbose" emit more timing information. I have thus added
a lot more logging around.
* include/abg-comparison.h ({diff, corpus_diff,
diff_context}::do_log): Declare member functions.
* include/abg-corpus.h (corpus::do_log): Likewise.
* src/abg-comparison-priv.h (diff_context::priv::do_log_): Add new
data member.
(diff_context::priv::priv): Initialize the new data member.
* src/abg-comparison.cc ({diff, corpus_diff,
diff_context}::do_log): Define member functions.
(diff_context::maybe_apply_filters): Add timing logs to applying
filters and propagating categories.
(corpus_diff::priv::apply_filters_and_compute_diff_stats): Add
timing logs to applying and propagating filters to changed
functions, variables, unreachable & leaf type changes,
suppressions application.
* src/abg-corpus-priv.h (corpus::priv::do_log): Add new data
member.
(corpus::priv::priv): Initialize it.
* src/abg-corpus.cc (corpus::do_log): Define member functions.
* src/abg-reader.cc (reader::do_log): Likewise.
(reader::read_corpus): Add timing log around the invocation of
perform_late_type_canonicalizing.
* tools/abidiff.cc (set_diff_context_from_opts): Set logging.
(main): Add timing logging for diff computing, changes analysis &
report generation.

Hello,
Up until now, a kernel whitelist was expected to be a ini file with a
section having a name ending with the word "whitelist". Nowadays,
they are called "stablelist", so the name of the section ends up with
"stablelist". This patch makes
gen_suppr_spec_from_kernel_abi_whitelists support that.
* src/abg-tools-utils.cc
(gen_suppr_spec_from_kernel_abi_whitelists): Support section name
that ends with the word 'stablelist'.

Hello,
When applying a filter to a corpus_diff node, visit each diff node
only once. This can have some serious performance impact when there
are a lot of diff nodes to visit.

Hello,
This patch allows to avoid applying filters on interface diff node
sub-graphs because those filters are useful for interface impact
analysis only, which is not needed in the leaf-node report, for
instance. When using the leaf-node report, this capability speeds up
corpus_diff::apply_filters_and_suppressions_before_reporting, hence
the functions like corpus_diff::{has_incompatible_changes,
has_net_subtype_changes} are sped up too.
That patch thus adds a --no-change-categorization option to abidiff to
avoid doing that change categorization (A.K.A applying filters).
* doc/manuals/abidiff.rst: Document the new
--no-change-categorization option.
* doc/manuals/kmidiff.rst: Likewise.
* include/abg-comparison.h
(diff_context::perform_change_categorization): Declare new
accessor member functions.
* src/abg-comparison-priv.h
(diff_context::priv::perform_change_categorization_): Add new data
member.
(diff_context::priv::priv): Initialize the new data member.
* src/abg-comparison.cc
(diff_context::perform_change_categorization): Define new accessor
member functions.
(corpus_diff::priv::apply_filters_and_compute_diff_stats):
Don't apply filters on the diff node sub-graphs of interfaces when
the user requested "no change categorization".
* tools/abidiff.cc (options::perform_change_categorization): New
data member.

(display_usage): Add a help string for the new
--no-change-categorization.

Hello,
When marking leaf nodes, if interface impact analysis is not required,
then avoid visiting the same diff node twice when walking the diff
graph. Allowing to visit the same diff node twice would be useful so
that the sub-graph of each interface diff node would be walked in full
to determine the impact of each leaf diff node on each interface. But
if such impact analysis is not required, then we can just visit each
diff graph node once and speed up things greatly in leaf node
reporting mode.
* src/abg-comparison.cc (corpus_diff::mark_leaf_diff_nodes): If
impact analysis is not required, visit each node just once.

Hello,
Categorizing a diff graph with a thousands of function diff nodes takes a
lot of time. At that point, categorizing each node has
harmful/harmless is showing up in the profile, particularly because
has_var_type_cv_qual_change and to a lesser extend
class_diff_has_harmless_odr_violation_change perform some structural
comparison still, oops. This patch avoids doing that. On my machine,
the categorizing of each node goes from around 130ms to 92 ms.
* src/abg-comp-filter.cc
(class_diff_has_harmless_odr_violation_change)
(has_var_type_cv_qual_change): Avoid doing structural comparison
here.
