@@ -7,22 +7,23 @@ The following changes in version 1.23 affect C/C++ analysis in all applications.
| **Query** | **Tags** | **Purpose** |
|-----------------------------|-----------|--------------------------------------------------------------------|
| Hard-coded Japanese era start date (`cpp/japanese-era/exact-era-date`) | reliability, japanese-era | This query is a combination of two old queries that were identical in purpose but separate as an implementation detail. This new query replaces Hard-coded Japanese era start date in call (`cpp/japanese-era/constructor-or-method-with-exact-era-date`) and Hard-coded Japanese era start date in `struct` (`cpp/japanese-era/struct-with-exact-era-date`). Results are not shown on LGTM by default. |
| Signed overflow check (`cpp/signed-overflow-check`) | correctness, security | Finds overflow checks that rely on signed integer addition to overflow, which has undefined behavior. Example: `a + b < a`. Results are shown on LGTM by default. |
| Pointer overflow check (`cpp/pointer-overflow-check`) | correctness, security | Finds overflow checks that rely on pointer addition to overflow, which has undefined behavior. Example: `ptr + a < ptr`. Results are shown on LGTM by default. |
| Signed overflow check (`cpp/signed-overflow-check`) | correctness, security | Finds overflow checks that rely on signed integer addition to overflow, which has undefined behavior. Example: `a + b < a`. Results are shown on LGTM by default. |
## Changes to existing queries
| **Query** | **Expected impact** | **Change** |
|----------------------------|------------------------|------------------------------------------------------------------|
| Comparison of narrow type with wide type in loop condition (`cpp/comparison-with-wider-type`) | Higher precision | The precision of this query has been increased to "high" as the alerts from this query have proved to be valuable on real-world projects. With this precision, results are now displayed by default in LGTM. |
| Hard-coded Japanese era start date in call (`cpp/japanese-era/constructor-or-method-with-exact-era-date`) | Deprecated | This query has been deprecated. Use the new combined query Hard-coded Japanese era start date (`cpp/japanese-era/exact-era-date`) instead. |
| Hard-coded Japanese era start date in struct (`cpp/japanese-era/struct-with-exact-era-date`) | Deprecated | This query has been deprecated. Use the new combined query Hard-coded Japanese era start date (`cpp/japanese-era/exact-era-date`) instead. |
| Hard-coded Japanese era start date (`cpp/japanese-era/exact-era-date`) | More correct results | This query now checks for the beginning date of the Reiwa era (1st May 2019). |
| Non-constant format string (`cpp/non-constant-format`) | Fewer false positive results | Fixed false positive results triggrered by mismatching declarations of a formatting function. |
| Sign check of bitwise operation (`cpp/bitwise-sign-check`) | Fewer false positive results | Results involving `>=` or `<=` are no longer reported. |
| Too few arguments to formatting function (`cpp/wrong-number-format-arguments`) | Fewer false positive results | Fixed false positive results triggered by mismatching declarations of a formatting function. |
| Too many arguments to formatting function (`cpp/too-many-format-arguments`) | Fewer false positive results | Fixed false positive results triggered by mismatching declarations of a formatting function. |
| Unclear comparison precedence (`cpp/comparison-precedence`) | Fewer false positive results | False positive results involving template classes and functions have been fixed. |
| Comparison of narrow type with wide type in loop condition (`cpp/comparison-with-wider-type`) | Higher precision | The precision of this query has been increased to "high" as the alerts from this query have proved to be valuable on real-world projects. With this precision, results are now displayed by default in LGTM. |
| Non-constant format string (`cpp/non-constant-format`) | Fewer false positive results | Fixed false positive results triggrered by mismatching declarations of a formatting function. |
| Wrong type of arguments to formatting function (`cpp/wrong-type-format-argument`) | More correct results and fewer false positive results | This query now understands explicitly-specified argument numbers in format strings, such as the `1$` in `%1$s`. |
