I agree, a single repo (or alternatively making libutil it's own repo) is
necessary if we want one binary, and I think we do.

Even if submodules was possible, I do not think they are a good solution.
Using submodules is unpleasant and pointless since all could is under our
control. I think submodules should only be used for code that you do not
have control over but need the source code for. Either you have separate
repos and have normal compile time dependencies (require that the libraries
are installed) or you put everything in one place, one repo.

I see the separation of sbase and ubase into two repositories as basically
equivalent to the a single repo with a sbase directory and a ubase directory,
except better when it comes to tagging new versions, but since there reason
to have separate releases for these, it doesn't really make a difference.
So simply putting sbase and ubase in two different directories in the same
repo, and then put a makefile there to build all of it into one binary would
be step up, of course there would be some linkage problems and making them
share libutil would be the next step up. Of course, it should be possible
to select if you want ubase included in your binary or not, is the point
of the separation in the first place.

I think there should be one directory called "portable" containing only tools
from sbase, and one directory called "linux" containing the tools from ubase
and maybe even symlinks to the tools in "portable". This structure would allow
us to add implementations for other operating systems as well. If we add
symlinks to the tools in "portable" to "linux", each directory could have
it's own makefile. But I'm not sure this is preferable over a single Makefile
in the root directory.

As mentioned in an other branch of this conversation, I think we should
have a base with only the POSIX tools but than have additional optional
tools, which could be group into overlapping categories, as you can select
what you want on your system.

The problem is that sbase and ubase each include a version of libutil, whith 
some
functions which are the same, and some other wich serve the same function but
vary in implementation due to version history.

git submodules are kinda meh I think for this problem, because it wouldn't 
change
the problem of source code duplication (and of versions drifting apart) between
the 2 projects, as libutil is part of both sbase and ubase trees (not mereley 
the
umbrella-box project).

I believe we should put what are currently sbase and ubsase in a single git 
repository,
sharing all that is portably sharable, but still separating utilities that are 
portable
from linux-specific ones.

I think sbase and ubase should try to provide useful, well-implemented, suckless
utilities. If we want POSIX utilities, let's add them! But I don't think we 
should
restrain us from doing that. sbase's sponge and cols is so useful I'm constantly
using them, even though I normally use busybox.

IMHO, if the intention behind sbase was to provide a minimal portable POSIX 
utilities implementation, anything not fitting that definition should be moved 
out of sbase.

A separate project, perhaps called [insert_letter]base, could cover the 
utilities not in POSIX which are common in Unix-like systems.

The problem of having separate *box executables could be solved by creating an 
"umbrella" *box project, perhaps having sbase, ubase and [insert_letter]base as 
git submodules, and deciding what to build based on the contents of config.mk.

I think we should keep the implementation of each tool as minimal as
possible, but POSIX-complete, and of course common tools such as
install(1) and tar(1). However, actually using a system that is
nothing more than POSIX is very cumbersome. And I think it is a better
solution to implement non-standard tools when possible to address
usability issues, e.g. implementing sponge(1) instead of -i for sed(1).

However, if the system isn't actually intended for be used
interactively via the command line, e.g. on embedded devices
or a service running in a container, there is no for non-standard
tools such as sponge(1), and it ought to be easy to select what
you want on your system. I suggest that tools be group into a
few categories (unless they are organised into separate directories
I see no reason one tool couldn't be in multiple categories).

These categories could for example:
- "posix" for all POSIX tools,
- "lsb" for all LSB tools
- "users" for account management
- "extra" for other common tools
- "common" for "posix", "lsb", "users", and "extra"
- "interative" for tools that only make since of when
  a lot via the terminal
- "all" for every implemented tool

Maybe these should also be subdivided into "portable" and "linux".

The user could then specify the tools to include either by
setting BIN when running make(1) or by saying "yes" or "no" to
each category (of course each category would have a default
option), e.g. POSIX=yes INTERACTIVE=no.

This would be my idea as well. It also wouldn't be that difficult
to let people pick and choose which sets of tools to include in the
final -box via config.mk or similar. I would stick with only the
high-level sets and leave the omission of individual tools up to
the "user" (I already do this because I prefer a few tools from
OpenBSD even when using Linux).

> Also I'm not sure whether we should keep the goal of being POSIX-compliant.

I also agree with this. POSIX, like everything designed by committees,
is full of bad and/or incomplete ideas. I think that having a set
of tools that isn't GNU/spaghetti but still supports some of the
good non-POSIX options (for example sponge, xargs -P, working tar,
etc.) would be nice to have.

Re: [dev] [sbase] Defining scope of sbase and ubase

2024-03-08 Thread Elie Le Vaillant
Hi,

I think one of the main current issues with the current
organization of sbase's and ubase's code, is that while
they share parts of code (some parts of libutil are shared),
they do not actually have it in common. As a result, changes
to shared parts of libutil in sbase are not reflected in ubase,
and vice-versa.

Some parts of ubase's libutil are not portable, so indeed it
makes sense that they are ubase-specific. But some, such as
recurse, strtonum, strl*, ealloc, eprinf, and maybe others,
serve the same exact function as in sbase, but sometimes
vary in implementation, because they didn't receive the same
patches.

So I wonder:
- Is this a problem that needs fixing? (I think yes)
- How do we fix it?

We could sync both periodically, applying whichever patch change
both *base's libutil to both.

Another idea could be to have both in the same git repository,
allowing libutil (and possibily more code, like libutf if we
ever need to) to be shared between them both without syncing
them back and forth. My idea would be something like this:

sbase/
  portable/
ls.c
cols.c
...
  unportable/
ps.c
kill.c
...
  libutf
  libutil/
portable
unportable
  Makefile

This could fix the "multiple -box" problems. This would require
rewriting some parts of the Makefile (for example, having PORTABLEBIN
and UNPORTABLEBIN to select whether or not we want the unportable
utilities; the mkbox script also), and could also provide a solution for
the "moretools" repo by having it being a separate directory in this
hypothetical repository.

Also I'm not sure whether we should keep the goal of being POSIX-compliant.
ls doesn't columnate, we have (non-standard) cols to do this. sed doesn't
have the -i flag, we have sponge for this. cron isn't specified by POSIX,
only crontab is. Maybe toybox roadmap's section on POSIX is relevant:
https://landley.net/toybox/roadmap.html

I think we should try and implement a minimal Unix-like userspace,
and allow ourselves some freedom on what to implement. We already
do this with sponge and cols. On ubase it is true also, with ctrlaltdel
for example. I do not see why not do it more.

Overall I think bringing everything in the same repository, with
what is now sbase and ubase in separate directories rather than
separate repositories, would fix both the current situation, and
allow for a "sextra"/"uextra" directory for supplementary tools.

Mattias Andrée already proposed this back when he proposed a patch
for shuf(1):

I think this could fix the current situation, with code on
different versions split between 2 repositories and ultimately
2 -box binaries, and allow a broader scope without impeding the
goals of minimalness of sbase/ubase.
