[dpdk-dev] [PATCH 0/3] more commits checks

[Thomas Monjalon]

The script check-git-log.sh helps to keep a consistent git history.
Scrolling/parsing the history is easier when we are used to some
rules.

[dpdk-dev] [PATCH 1/3] scripts: check spacing after commit references

[Thomas Monjalon]

A blank line between "Fixes" and "Signed-off-by" helps to
separate information in blocks.

Given the preference for including documentation in with the code changes,
we should perhaps exclude any doc changes when making this check.

I think you forgot the '$' for drivers in the line just above.

Yes we can exclude doc/ and config/.

No it is a plain "drivers:" for cases where we have net and crypto.
(it is an addition from your original idea)
But I forgot to remove bad=$( which I've moved to the first line.

V2 on going

[dpdk-dev] [PATCH v2] scripts: check headline of drivers commits

[Thomas Monjalon]

From: Nelio Laranjeiro <nelio.laranjeiro@6wind.com>

A driver patch under net should start with "net/<driver name>" or if
a patch touch multiple drivers, it should only start with "net:".
The same apply for crypto.
A patch touching all drivers (net + crypto) should start with "drivers:".

Longer prefixes like "net/mlx:" (for mlx4/mlx5) or "net/e1000/base:" are
handled by not checking the colon.

The directories doc/ and config/ are ignored because a driver patch
can modify them.
