lib: Remove sys_fsusage()

2026-02-15T10:42:34+00:00

"man statfs" on Linux says "Unless you need the f_type field, you
should use the standard statvfs(3) interface instead.". We don't need
f_type to get disk usage :-)

We lose some of the older compatibility layers. Should these ever be
needed again, we should add them to lib/util/statvfs.c an the single
interface to retrieve file system usage info.

specify some deps on private libs actually used directly

2025-01-02T17:01:30+00:00

Lots of samba libraries has incomplete dependencies listed
in wscript files.  This usually is not a problem since the
link line includes dependencies of their dependencies of
their dependencies, and somewhere down that line all immediate
dependencies which are missing are actually present.  But
sometimes this becomes a problem when a library does not
declare direct dependency on at least one private library
which it actually uses: in case no private library is
listed as direct dependency, private library directory is
not put into RUNPATH of the resulting binary, so the binary
can not find its own dependencies.

Fix a few such places, including some libraries which are
a part of public abi (libsmbldap, libndr).

util: add a crypt wrapper, derived from dsdb:password_hash

2024-12-20T07:04:31+00:00

This is going to be used by the dsdb password_hash module, and exposed
to Python via pyglue.

We're doing this because Python 3.13 has dropped crypt from the Python
standard library.

util: add stable sort functions

2022-12-01T22:56:39+00:00

Sometimes (e.g. in lzxpress Huffman encoding, and in some of our
tests: c.f. https://lists.samba.org/archive/samba-technical/2018-March/126010.html)
we want a stable sort algorithm (meaning one that retains the previous
order of items that compare equal).

The GNU libc qsort() is *usually* stable, in that it first tries to
use a mergesort but reverts to quicksort if the necessary allocations
fail. That has led Samba developers to unthinkingly assume qsort() is
stable which is not the case on many platforms, and might not always
be on GNU/Linuxes either.

This adds four functions. stable_sort() sorts an array, and requires
an auxiliary working array of the same size. stable_sort_talloc()
takes a talloc context so it ca create a working array and call
stable_sort(). stable_sort_r() takes an opaque context blob that gets
passed to the compare function, like qsort_r() and ldb_qsort(). And
stable_sort_talloc_r() rounds out the quadrant.

These are LGPL so that the can be used in ldb, which has problems with
unstable sort.

The tests are borrowed and extended from test_ldb_qsort.c.

When sorting non-trivial structs this is roughly as fast as GNU qsort,
but GNU qsort has optimisations for small items, using direct
assignments of rather than memcpy where the size allows the item to be
cast as some kind of int.
