don't even call the date util at all, to fix the

git itself can just take an epoch, and it will
do whatever it will do. yes.

even if i unset PATH before running lbmk, it is
reinitialised because of the shebang. if no PATH
exists, then it's either a broken system and you
have bigger problems, or you have some weird
system that uses something else.
our job is not to fix the world. there was no
scenario in which this check would even trigger
an error or fallback, so just remove it.

i've been careful to makely only use it on AND operations,
not onse that use OR. a lot of blocks are not condensed,
unlike previously when this design was used.
i removed the condensed design because it made the code
allegedly easier to read, but i found it harder to read
and found the code looked dirty. this change makes it
clean again, but i've done it in a way where the shorthand
conditional statements are easy to understand for most
people. this strikes a compromise; i would go further.

use the simpler logic recently introduced, generalised
but it only sets variables to empty. this is safer than
the previous design, and brings the same reduction in
sloccount overall since i wasn't doing anything other
than emptying variables anyway, when it was used before.
i didn't like the long list of variables inside files,
so this makes everything more readable.

the previous patch was half the battle. now that
annoying person who complained on irc should be
happy.
someone complained about having to enter git
name/email when just doing e.g. ./mk inject
a valid complaint, but their attitude kinda
stunk. oh well. this patch should satisfy them.

Some users have it in a file e.g. inside ~/.gitconfig
Those users are currently forced to set git config
globally by lbmk. We only need to check that a git
config is set, regardless of scope, because coreboot
needs it in parts of its build system when used on
lbmk.
This prevents a pointless error report for users who
have their git config on such a scope. Thanks go to
Hendrik Jäger for reporting this to me.
Yes, thank you. Further context:

i added a fake -t option, which doesn't actually
read optarg, so that -t usage can just override
the normal template. mkhtemp isn't ready for
distros yet, but it's ready for lbmk.
i hacked the makefile to also copy the binary to
mktemp, and i set PATH in lbmk so that this binary
is used insttead of the one on your system.
that way, upstream projects use it.

Don't do one repository for all remotes. Do one *clone* per
remote.
This also means that users no longer download information twice,
in practice, because the backup repository will only be downloaded
if the main one didn't work.
Theoretically, this change is makes the process less efficient, but
in practise it's more reliable now.
We do now use --mirror on the git clone command for caches, but we
already did git pull --all before.
This just ensures that we absolutely have all local code.
NOTE:
The new code isn't used by default. To use it, you must do:
export XBMK_CACHE_MIRROR="y"
Otherwise, the old behaviour will continue to be used. This is
because the new code, while correct, puts more strain on upstream
servers (more code being downloaded), and can result in higher amounts
of disk space being used. The old behaviour wasn't broken, so we'll
also support that method.
TODO: perhaps also have a check in place to re-use both caches,
where available, regardless of XBMK_CACHE_MIRROR?

also, the check is -e, not -d, because we
might be operating on a symlink.
it's a bit hacky but this should work.

xbmkdir checks if a directory exists, before running
mkdir, and then still uses -p
i was testing xbmk on arch linux today, and noticed
that it errored out when a directory already exists.
i'm mitigating against buggy or differently behaving
mkdir implementations this way, by wrapping around
it.

this allows me to remove several eval calls, and the

the new check is still retained, to the extent that
the lock file still contains the TMPDIR string, and
it's checked whether this changed during execution.
however, the current TMPDIR handling is over-engineered
and prevents the re-use of project source caches when
doing release builds; this means that the release builds
happen much more slowly, especially for slow internet
connections.
this change *fixes* that bug. now release builds once
again re-use the main cache/ directory.

be a bit less pedantic about if else clauses. leave the
big ones still with then on separate lines, where else
is specified.
also unroll a few condensed code lines where i missed
a few.
sloccount 2303 in lbmk. that's still only slightly bigger
than libreboot 20260907 which was 2180, and still much
smaller than libreboot 20230625 which was 3322.
this is *without* the condensed codelines, so now the only
thing that's reduced is the overall amount of logic present
in the build system.
and i should clarify that lbmk is presently much more powerful
than both of those two versions (20160907/20230625).
the 2016 one is useful for comparison historically, since that
was the last major version of libreboot prior to the great
second coming of leah in 2021; and the 2023 june release was
basically the last one before the great audits of 2023 to
2025 began.
not to brag (not much anyway), but all of this means that lbmk
is an insanely efficient build system, considering all the
features it has and what it does.
i unrolled the condensed code style in lbmk, making the scripts
a lot easier to read, because i received complainst about the
condensed style previously used; nicholas chin and alper nebi
yasak both told me that it sucked, and riku viitanen had hinted
at that same fact several months prior.
so hopefully now, lbmk is a bit nicer. those and other people
often find it challenging to challenge me because for reason
they assume i'll get upset and fly off the handle, but it's the
opposite. i want constant criticism, so that i know to improve!
