#Intro
|
||||
This directory contains tools, which can be used for checking the health of the project, like build/run time analyzers, lints, etc.
|
||||
|
||||
#Usage
|
||||
Unless it's stated differently, these scripts should be called from a given source directory, where you want the checks to be performed, for instance:
|
||||
|
||||
`og@ghetto:~/dev/monero$ utils/health/clang-build-time-analyzer-run.sh`
|
||||
|
||||
##ClangBuildAnalyzer
|
||||
`utils/health/clang-build-time-analyzer-run.sh`
|
||||
The CBA helps in finding culprints of slow compilation.
|
||||
On the first run, the script will complain about the missing ClangBuildAnalyzer binary and will point you to another script, which is able to clone and build the required binary.
|
||||
|
||||
##clang-tidy
|
||||
`utils/health/clang-tidy-run.sh`
|
||||
Performs Lint checks on the source code and stores the result in the build directory. More information on the [home page](https://clang.llvm.org/extra/clang-tidy/).
|
||||
|
||||
|
||||
##Valgrind checks
|
||||
`utils/health/valgrind-tests.sh`
|
||||
This script is able to run valgrind's callgrind, cachegrind and memcheck for a given set of executables.
|
||||
It expects ONE PARAMETER, which points to a file with paths to executables and their arguments, written line by line. For example:
|
||||
|
||||
```
|
||||
ls -l -h
|
||||
build/tests/unit_tests/unit_tests
|
||||
```
|
||||
|
||||
The `*.out` results can be interpreted with the `kcachegrind` tool.
|
||||
The memcheck output is just a readable text file with a summary at the end.
