# Code Quality Tools
|
|
|
|
The systemd project has a number of code quality tools set up in the source
|
|
tree and on the github infrastructure. Here's an incomprehensive list of the
|
|
available functionality:
|
|
|
|
1. Use `ninja -C build test` to run the unit tests. Some tests are skipped if
|
|
no privileges are available, hence consider also running them with `sudo
|
|
ninja -C build test`. A couple of unit tests are considered "unsafe" (as
|
|
they change system state); to run those too, build with `meson
|
|
-Dtests=unsafe`. Finally, some unit tests are considered to be very slow,
|
|
build them too with `meson -Dslow-tests=true`. (Note that there are a couple
|
|
of manual tests in addition to these unit tests.)
|
|
|
|
2. Use `./test/run-integration-tests.sh` to run the full integration test
|
|
suite. This will build OS images with a number of integration tests and run
|
|
them in nspawn and qemu. Requires root.
|
|
|
|
3. Use `./coccinelle/run-coccinelle.sh` to run all
|
|
[Coccinelle](http://coccinelle.lip6.fr/) semantic patch scripts we ship. The
|
|
output will show false positives, hence take it with a pinch of salt.
|
|
|
|
4. Use `./tools/find-double-newline.sh recdiff` to find double newlines. Use
|
|
`./tools/find-double-newline.sh recpatch` to fix them. Take this with a grain
|
|
of salt, in particular as we generally leave foreign header files we include in
|
|
our tree unmodified, if possible.
|
|
|
|
5. Similar use `./tools/find-tabs.sh recdiff` to find TABs, and
|
|
`./tools/find-tabs.sh recpatch` to fix them. (Again, grain of salt, foreign
|
|
headers should usually be left unmodified.)
|
|
|
|
6. Use `ninja -C build check-api-docs` to compare the the list of exported
|
|
symbols of `libsystemd.so` and `libudev.so` with the list of man pages. Symbols
|
|
lacking documentation are highlighted.
|
|
|
|
7. Use `ninja -C build hwdb-update` to automatically download and import the
|
|
PCI, USB and OUI databases into hwdb.
|
|
|
|
8. Use `ninja -C build man/update-man-rules` to update the meson rules for
|
|
building man pages automatically from the docbook XML files included in
|
|
`man/`.
|
|
|
|
9. There are multiple CI systems in use that run on every github PR submission.
|
|
|
|
10. [Coverity](https://scan.coverity.com/) is analyzing systemd master in
|
|
regular intervals. The reports are available
|
|
[online](https://scan.coverity.com/projects/systemd).
|
|
|
|
11. [oss-fuzz](https://oss-fuzz.com/) is continuously fuzzing the
|
|
codebase. Reports are available
|
|
[online](https://oss-fuzz.com/v2/testcases?project=systemd).
|
|
|
|
Access to Coverity and oss-fuzz reports is limited. Please reach out the the
|
|
maintainers is you need access.
