This patch extends our SARIF output to capture relationships between
locations within a result (§3.34). In particular, this captures
chains of #includes relating to diagnostics and to events within
diagnostic paths.
For example, consider:
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;
| ^
PATH/include-chain-1-1.h:2:5: note: previous declaration of 'q' with type 'int'
2 | int q;
| ^
With this patch, the SARIF output captures the include information for
the two results, so that e.g. result[0]'s location[0] has:
"relationships": [{"target": 0,
"kinds": ["isIncludedBy"]}],
"id": 0
and the "note" in relatedLocations[0] has:
"message": {"text": "previous declaration of 'q' with type 'int'"},
"relationships": [{"target": 2,
"kinds": ["isIncludedBy"]}],
"id": 2},
where these reference new locations within relatedLocations, such as this for
the "#include "include-chain-1-1.h" line in include-chain-1.h:
{"physicalLocation": {"artifactLocation": {"uri": include-chain-1.h",
"uriBaseId": "PWD"},
"region": {"startLine": 5},
"contextRegion": {"startLine": 5,
"snippet": {"text": "#include \"include-chain-1-2.h\"\n"}}},
"id": 1,
"relationships": [{"target": 0,
"kinds": ["includes"]},
{"target": 4,
"kinds": ["isIncludedBy"]}]},
effectively capturing the inclusion digraph in SARIF form:
+-----------------------------------+ +----------------------------------+
|"id": 0 | |"id": 2 |
| error: "conflicting types for 'p';| | note: previous declaration of 'p'|
| have 'char'"| | | with type 'int'") |
| in include-chain-1-2.h | | in include-chain-1-1.h |
+-----------------------------------+ +----------------------------------+
| |
| included-by | included-by
V V
+--------------------------------+ +--------------------------------+
|"id": 1 | |"id": 3 |
| #include "include-chain-1-2.h" | | #include "include-chain-1-1.h" |
| in include-chain-1.h | | in include-chain-1.h |
+--------------------------------+ +--------------------------------+
| |
| included-by | included-by
V V
+------------------------------------+
|"id": 4 |
| The #include "include-chain-1.h" |
| in include-chain-1.c |
+------------------------------------+
Locations only gain "id" fields if they need one, and the precise
numbering of the IDs within a result is an implementation detail (the
order in which references to the locations are made).
To test all this non-trivial JSON from DejaGnu I needed to adapt the
python testing code used by gcov, adding a new run-sarif-pytest based
on run-gcov-pytest.
Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Successful run of analyzer integration tests on x86_64-pc-linux-gnu.
Pushed to trunk as r15-2354-g4d1f71d49e396c.

+ 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'")
