[PATCH] fflush.3: SEE ALSO: Add fpurge(3)

[Alejandro Colomar]

fpurge(i_stream) does the same as fflush(i_stream), AFAIK.

Hi Michael,

This is the first of many separate patches that I had pending for you.
Some of them I already sent you, and you should ignore the old versions.
Some of them are new.
Please review them thoroughly, as I may have sent some patch that wasn't
ready.  In theory I have reviewed them enough, but there are a lot, and
I might have overlooked something.


When you review this "set", I'll send you another one about the SYNOPSIS.


Thanks,

Alex

[PATCH] scripts/bash_aliases: man_gitstaged(): Script around a porcelain git command

[Alejandro Colomar]

The output of 'git status' is not stable.

The more stable 'git status --porcelain' is more complex,
and scripting around it would be more complex.

However, 'git diff --staged --name-only' produces
the output that we were lookiong for.

Glibc uses 'const' for the basename() parameter.
Fix the prototype.

Yes, but see basename(3p):

    SYNOPSIS
       #include <libgen.h>

       char *basename(char *path);

       ...

       The basename() function may modify the string pointed to by  path,
       and may return a pointer to internal storage. The returned pointer
       might be invalidated or the storage might be overwritten by a sub‐
       sequent  call  to  basename().  The returned pointer might also be
       invalidated if the calling thread is terminated.

I'll skip this patch.

Thanks,

Michael

It's POSIX that states that, so yes, I'll drop it.

[PATCH] open.2: Fix bug in linkat(2) call example

[Alejandro Colomar]

AT_EMPTY_PATH works with empty strings (""), but not with NULL
(or at least it's not obvious).

The relevant kernel code is the following:

linux$ sed -n 189,198p fs/namei.c
	result->refcnt = 1;
	/* The empty path is special. */
	if (unlikely(!len)) {
		if (empty)
			*empty = 1;
		if (!(flags & LOOKUP_EMPTY)) {
			putname(result);
			return ERR_PTR(-ENOENT);
		}
	}

[PATCH] copy_file_range.2: Update cross-filesystem support for 5.12

[Alejandro Colomar]

Linux 5.12 fixes a regression.

Cross-filesystem (introduced in 5.3) copies were buggy.

Move the statements documenting cross-fs to BUGS.
Kernels 5.3..5.11 should be patched soon.

State version information for some errors related to this.

Thanks for catching that. I had not pushed the patch, so 
I'll just drop it.

[PATCH] scripts/bash_aliases: Make man_lsfunc() more robust; Add sed_rm_ccomments().

[Alejandro Colomar]

This patch makes man_lsfunc() search for the function prototypes,
instead of relying on the current manual page formatting,
which might change in the future, and break this function.

It also simplifies the code, by reusing man_section().

Create a new function sed_rm_ccomments(), which is needed by
man_lsfunc(), and may also be useful in other cases.

clnt_spcreateerror(),
clnt_sperror(),
pmap_set(),
svc_register(),

[PATCH] bswap.3: bswap_*() are implemented using functions

[Alejandro Colomar]

See <bits/byteswap.h> in glibc.
These macros call functions of the form __bswap_N(),
which use uintN_t.

Eventhough it's true that they are macros,
it's transparent to the user.

The user will see their results casted to unsigned types
after the conversion do to the underlying functions,
so it's better to document these as the underlying functions,
specifying the types.

[PATCH] scripts/bash_aliases: srcfix

[Alejandro Colomar]

I clarified the code about two things:

- Checking how many arguments are being passed.
    Here, some functions didn't reject extra arguments when they
    weren't being used.  Fix that.
    I also changed the code to use $#, which is more explicit.
    And use arithmetic expressions, which better indicate that
    we're dealing with numbers.

- Remove unneeded options from sort.
    Reported-by: Stefan Puiu <stefan.puiu@gmail.com>
    After Stefan asked about why am I using 'sort -V',
    I noticed that I really don't need '-V', and it may confuse
    people trying to understand the script, so even though I
    slightly prefer the output of 'sort -V', in this case, it's
    better to use the simpler 'sort' (yet I need 'sort', to
    maintain consistency in the results (find is quite random)).

[PATCH] Makefile: Fix bug when running in parallel

[Alejandro Colomar]

Prerequisites can run in parallel.  This wouldn't make any sense
when uninstalling and installing again.

For that, use consecutive commands, which run one after the other
even with multiple cores.

[PATCH] .gitignore: Add file

[Alejandro Colomar]

Ignore everything new by default.

This avoids having to update the .gitignore when we need to ignore
something new.  It also avoids accidents that may add an unwanted
temporary file.

Why '**'? Is '*' not sufficient in both of the above?

You're right.  '*' is sufficient.  Please fix it yourself :)

[PATCH] Makefile: Simplify error handling

[Alejandro Colomar]

Instead of having to write '|| exit $$?' all the time,
use the shell's '-Eeuo pipefail' options, which handle
errors even better.  However, pipefail needs bash,
so POSIX sh (default) is not valid.

Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com>

Hi Michael,

I'm not sure how much POSIX sh compatibility is needed for the man pages
Makefile.  There are probably projects out there that don't have bash,
and still want to use it.  So maybe we should't apply this.  I don't know.
Up to you.

Thanks,

Alex

I think I'll skip this one. I'm not sure if it might cause some
problem for Debian, where the default shall is dash(1), I believe.

Debian has dash(1) as the default _non-interactive_ shell, but also has 
bash(1) as the default _interactive_ shell.  See 
<https://wiki.debian.org/Shell>.

I can confirm that using Debian (sid) myself (and having not installed 
bash(1) myself) I'm using this Makefile without any issue.

However, it's true that other smaller distros might not come with bash(1).

So still up to you :)

I forgot to CC the Debian maintainer of manpages in this patch this 
time; fixed.  I also CCed the bash(1) and dash(1) Debian maintainers, 
just in case they have any comments.

Thanks,

Alex

Some I looked at more closely. Others (e.g., patches to the scripts),
I've taken on trust.

Okay.

Re: [PATCH] Makefile: Use standard features (IMPORTANT: default prefix changed)

Hi Michael,

Hmmm.  I have some minor reasons to add it, but not a really good one.

* Some editors don't recognize 'Makefile' as a special name, so the 
shebang helps detecting which language the file is using (e.g., for 
coloring).

* I tend to subdivide a big Makefile into a small Makefile and many 
submakefiles stored in <./libexec/>.  Those obviously need different 
names, and given that the makefile extension is not very standard (I use 
.mk), having a shebang helps knowing what the file is.  After that, I 
also have it on the main Makefile for consistency.   But here we only 
have one Makefile, so it doesn apply very much.

And some similar reasons.


Thanks,

Alex

I think I'll remove it. It is kind of idiosyncratic, leaves the
reader asking "why?".

[PATCH] open.2: Fix bug in linkat(2) call example

[Alejandro Colomar]

AT_EMPTY_PATH works with empty strings (""), but not with NULL
(or at least it's not obvious).

The relevant kernel code is the following:

linux$ sed -n 189,198p fs/namei.c
	result->refcnt = 1;
	/* The empty path is special. */
	if (unlikely(!len)) {
		if (empty)
			*empty = 1;
		if (!(flags & LOOKUP_EMPTY)) {
			putname(result);
			return ERR_PTR(-ENOENT);
		}
	}
