[PATCH 0/1] buildtools: clear out regex syntax warnings

[Ariel Otilibili]

Hello,

This is my first patch to the list; your feedback is much appreciated.

My aim is to understand the internals of DPDK.

While compiling from scratch, I came across these Python warnings.

Thank you,

Hi Ariel, thanks for the fix!

Acked-by: Robin Jarry <rjarry@redhat.com>

If you have time, I there are other bits that would need the same fix:

buildtools/get-numa-count.py:14:        numa_nodes.sort(key=lambda l: int(re.findall('\d+', l)[0]))
devtools/check-meson.py:54:        if re.match('^ *\t', code):
doc/api/generate_doxygen.py:8:pattern = re.compile('^Preprocessing (.*)...$')

Cheers.

Good, then; I'll push them in a subsequent series.

Those fixes are little one-liners worth backporting.

Please add a Fixes: tag identifying the commit introducing the issue,
then Cc: stable@dpdk.org.
If you need more details on what is expected, see

and https://doc.dpdk.org/guides/contributing/patches.html#patch-for-stable-releases
