A class for sarif_objects that own a "namespace" of numeric IDs for
managing location objects within them. Currently (SARIF v2.1.0)
this is just for sarif_result (section 3.28.2), but it will likely
eventually also be for notification objects; see
https://github.com/oasis-tcs/sarif-spec/issues/540
Consider locations with chains of include information e.g.
> include-chain-1.c:
> #include "include-chain-1.h"
include-chain-1.h:
| // First set of decls, which will be referenced in notes
| #include "include-chain-1-1.h"
|
| // Second set of decls, which will trigger the errors
| #include "include-chain-1-2.h"
include-chain-1-1.h:
| int p;
| int q;
include-chain-1-1.h:
| char p;
| char q;
GCC's textual output emits:
| In file included from PATH/include-chain-1.h:5,
| from PATH/include-chain-1.c:30:
| PATH/include-chain-1-2.h:1:6: error: conflicting types for 'p'; have 'char'
| 1 | char p;
| | ^
| In file included from PATH/include-chain-1.h:2:
| PATH/include-chain-1-1.h:1:5: note: previous declaration of 'p' with type 'int'
| 1 | int p;
| | ^
| PATH/include-chain-1-2.h:2:6: error: conflicting types for 'q'; have 'char'
| 2 | char q;

| 2 | int q;

Whenever a SARIF location is added for a location_t that
was #included from somewhere, we queue up the creation of a SARIF
location for the location of the #include. The worklist of queued
locations is flushed when the result is finished, which lazily creates
any additional related locations for the include chain, and the
relationships between the locations. Doing so can lead to further
include locations being processed. The worklist approach allows us
to lazily explore the relevant part of the directed graph of location_t
values implicit in our line_maps structure, replicating it as a directed
graph of SARIF locations within the SARIF result object, like this:
[0]: error in include-chain-1-2.h ("conflicting types for 'p'; have 'char'")
[1]: #include "include-chain-1-2.h" in include-chain-1.h
[2]: note in include-chain-1-2.h ("previous declaration of 'p' with type 'int'")
[3]: #include "include-chain-1-1.h" in include-chain-1.h
[4]: #include "include-chain-1.h" in include-chain-1.c
where we want to capture this "includes" graph in SARIF form:
. +-----------------------------------+ +----------------------------------+

Subroutine of json::compare for comparing a pairs of objects.

Referenced by json::value::compare().
|
staticinherited |
A deterministic total ordering for comparing json values, so that we can e.g. put them in std::map. This is intended to follow the condition for equality described in the JSON Schema standard (§4.3, “Instance equality”), as referenced by SARIF v2.1.0 (§3.7.3 "Array properties with unique values"), but has the following limitations: - numbers are supposed to be checked for "the same mathematical value", but in this implementation int vs float numbers won't compare as equal, and float number comparison is bitwise - strings are supposed to be "the same codepoint-for-codepoint", but this implementation doesn't take into account canonicalization issues.
