[PATCH] scripts/tags.sh: Prevent binary files appearing in cscope.files

[PATCH] scripts/tags.sh: Prevent binary files appearing in cscope.files

[Sergei Litvin]

PROBLEM

When executing the command `make COMPILED_SOURCE=1 cscope`, the resulting
`cscope.files` file contains filenames with the extensions *.rlib, *.rmeta,
and *.so.

SOLUTION

Modify the regular expression in the `all_compiled_sources()` function so
that only files with the extensions *.h, *.c, *.S, and *.rs are accepted.

We don't typically use titles like these in commits. (Same for the other patch.)

Missing Signed-off-by -- the one you wrote is below, in the part that
doesn't go into the commit, i.e. after the `---` line. (Same for the
other patch.)

Also consider using `-v2` in `git format-patch` to annotate which version it is.

By the way, this sounds like it could be backported? i.e. perhaps we
want a Fixes: tag and Cc: stable@vger.kernel.org.

Thanks!

[PATCH v2] scripts/tags.sh: Prevent binary files appearing in cscope.files

[Sergei Litvin]

When executing the command `make COMPILED_SOURCE=1 cscope`, the resulting
`cscope.files` file contains filenames with the extensions *.rlib, *.rmeta,
and *.so.

To fix this, modify the regular expression in the `all_compiled_sources()`
function so that only files with the extensions *.h, *.c, *.S, and *.rs are
accepted.

The issue has been introduced by commit 4f491bb6ea2a ("scripts/tags.sh: collect
compiled source precisely") which implemented the parsing of compiled sources
from *.cmd files instead of using the "find" command.

Thanks, looks good to me.  W/o this patch 'make COMPILED_SOURCE=1
cscope' is actually not usable on my system, as soon as some rust libs
are in my build tree, so thanks for fixing!

As this is a not really a build relevant bug, I think this should go via
some -next rather than a -fixes tree [1].

Miguel, are you with with it if I take this patch as well as the second
one [2] via kbuild-next?

(I tend to remove the Cc trailers from this patch here, as they are
incomplete.)

Kind regards,
Nicolas

Yes, of course, thanks!

Acked-by: Miguel Ojeda <ojeda@kernel.org>

(If the `cscope` target is actually broken in some cases, then I think
it would still be fine in -fixes; but since nobody complained so far,
I guess it is not that urgent anyway...).

When executing the command `make cscope`, the `cscope.files` file generated

To fix this, modify the functions `find_arch_sources()`,

`find_other_sources()` so that they can accept an unlimited number of filename
patterns as parameters for the search. Add the `setup_name_pattern()` function

be passed to the `find` utility via the new `pattern` variable.

To clarify, I meant this one for the other one, i.e. this one sounds a
bit more like a feature.

But I am not sure -- to decide whether it is a fix, it would be nice
to get a description of how each of them breaks something, to decide
whether it is a fix or not, e.g. the other one sounded to me like it
was a mistake because it added extra unexpected files (and I guess
that could in principle confuse tooling or perhaps makes `cscope`
print non-sense in some cases), but does it?

Similarly, for this one, what breaks "in practice" for the end user?
e.g. is there an error message, or does some workflow break, etc.? (It
would be nice to show it in the commit message if so.)

Finally, if this one is a fix too, then this should likely has the
Fixes: hash too.

(By the way, if you send a new version, please Cc the entire `RUST`
entry if you don't mind).

Thanks!

Cheers,
Miguel

Just to clarify, I meant to Cc in the header, rather than add everyone
as an explicit Cc tag -- the Cc: tag is (usually) meant to be a more
explicit Cc to indicate in the commit message that the particular
person had a chance to comment etc.

[ Some people do use it for every single Cc, but that is a minority
last time I took a look at it. I think it may make things easier for
some tooling, but it adds a lot of noise and reduces the signal of the
tag. ]

In any case, no need for a new version to change that! :)

Thanks!

Cheers,
Miguel

[PATCH] scripts/tags.sh: Add support for rust source files

[Sergei Litvin]

PROBLEM

When executing the command `make cscope`, the `cscope.files` file generated
by it includes only filenames with the extensions *.h, *.c, *.S and not includes
filenames with *.rs extensions.

SOLUTION

Modify the functions `find_arch_sources()`, `find_arch_include_sources()`,
`find_include_sources()`, and `find_other_sources()` so that they can accept an
unlimited number of filename patterns as parameters for the search. Add the
`setup_name_pattern()` function to convert these filename pattern parameters
into a list of parameters that can be passed to the `find` utility via the new
`pattern` variable.

This causes `make cscope` command to generate a `cscope.files` file that
contains *.rs files along with *.h, *.c, *.S

This is the second part of this patch:
https://lore.kernel.org/lkml/20260602121521.11650-1-litvindev@gmail.com/

which I have split into two parts, as suggested by Nicolas Schier here:
