-# NEWS for rsync 3.4.4 (8 Jun 2026)
-
-## Changes in this version:
-
-This is a conservative point release that backports regression fixes
-on top of 3.4.3.  No new features are included.
-
-### BUG FIXES:
-
-- Honour a relative alt-basis directory (e.g. `--link-dest=../sibling`,
-  `--copy-dest`, `--compare-dest`) on a daemon receiver running with
-  `use chroot = no`.  Such a path is re-anchored at the module root but
-  was then rejected by the receiver's secure open; it now works where
-  kernel-enforced confinement is available.  See the PORTABILITY note
-  below for the platform limitation.  Fixes #915.
-
-- sender: open a module-root-absolute path for a `path = /` module so a
-  daemon serving the filesystem root can satisfy absolute request
-  paths again.  Fixes #897.
-
-- flist: accept the missing-args mode-0 entry in recv_file_entry.
-  Fixes #910.
-
-- receiver: fix a false "failed verification -- update discarded" when
-  resuming a delta transfer with an absolute `--partial-dir`.
-
-- receiver: fix a NULL dereference on the delta discard path.
-
-- generator: cap the block s2length at the negotiated checksum length.
-
-- main: fix `--mkpath` with `--dry-run` for a file-to-file copy.
-  Fixes #880.
-
-- daemon: un-backslash escaped option args.  Fixes #829.
-
-- token: drain the matched-block insert deflate.  Fixes #951.
-
-- Fix the "update skips a file of a different type" case and the
-  daemon upload delete stats.
-
-- alloc: revert "zero all new memory from allocations".  Fixes #959.
-
-- Always clear the stat buffer and validate nanoseconds before use.
-
-### PORTABILITY / BUILD:
-
-- The relative alt-basis fix for daemon receivers (#915) relies on
-  kernel "stay below dirfd" path resolution -- `openat2(RESOLVE_BENEATH)`
-  on Linux 5.6+, or `openat()` with `O_RESOLVE_BENEATH` on FreeBSD 13+
-  and macOS 15+.  On platforms that lack it (Solaris, OpenBSD, NetBSD,
-  Cygwin and older Linux) `secure_relative_open()` deliberately rejects
-  any path with a `..` component, so relative alt-basis directories
-  remain unavailable there -- function traded for safety, matching the
-  trade-off already documented for the #715 fix.  Absolute alt-basis
-  paths are unaffected on every platform.
-
-- openat2 is now autodetected at configure time (HAVE_OPENAT2): the
-  `openat2(RESOLVE_BENEATH)` resolver is compiled in only when both
-  `<linux/openat2.h>` and the `SYS_openat2` syscall number are present,
-  fixing the build on older kernels/headers.  Fixes #924, #905, #900,
-  #904.
-
-- Fall back to do_mknod() when mknodat() / mkfifoat() are unavailable.
-  Fixes #896.
-
-- Install generated manpages correctly in an out-of-tree build.
-
-### DEVELOPER RELATED:
-
-- Added a CI workflow that builds this stable branch and runs the
-  `v34-stable-testsuite` regression suite against the built binary,
-  giving regression coverage without importing the full master test
-  suite into the stable branch.
-
-- Added a check-progs target for fleettest and extended the build
-  workflows to run on `*-stable` release branches.
-

-# NEWS for rsync 3.4.3 (20 May 2026)
-
-## Changes in this version:
-
-### SECURITY FIXES:
-
-Six CVEs are fixed in this release.  All six are assigned by
-VulnCheck as CNA.  Affected versions are 3.4.2 and earlier in every
-case.  Three of the six (CVE-2026-29518, CVE-2026-43617,
-CVE-2026-43619) require non-default daemon configuration to reach:
-the first and third need `use chroot = no` for a module, the second
-needs `daemon chroot = ...` set in rsyncd.conf.  Two (CVE-2026-43618,
-CVE-2026-43620) are reachable from a normal pull or a normal
-authenticated daemon connection.  The sixth (CVE-2026-45232) is
-reachable only when `RSYNC_PROXY` is set and the proxy (or a MITM)
-returns a pathological response.  Many thanks to the external
-researchers who reported these issues.
-
-- CVE-2026-29518 (CVSS v4.0 7.3, HIGH): TOCTOU symlink race condition
-  allowing local privilege escalation in daemon mode without chroot.
-  An rsync daemon configured with "use chroot = no" was exposed to a
-  time-of-check / time-of-use race on parent path components: a local
-  attacker with write access to a module could replace a parent
-  directory component with a symlink between the receiver's check and
-  its open(), redirecting reads (basis-file disclosure) and writes
-  (file overwrite) outside the module.  Default "use chroot = yes" is
-  not exposed.  `secure_relative_open()` (added in 3.4.0 for
-  CVE-2024-12086) was previously unused in the daemon-no-chroot
-  case; the fix enables it there and reroutes the sender's
-  read-path opens through it.  Reported by Nullx3D (Batuhan Sancak),
-  Damien Neil and Michael Stapelberg.
-
-- CVE-2026-43617 (CVSS v3.1 4.8, MEDIUM): Hostname/ACL bypass on an
-  rsync daemon configured with `daemon chroot = /X` in rsyncd.conf
-  when the chroot tree lacks DNS resolution support.  The
-  reverse-DNS lookup of the connecting client was performed *after*
-  the daemon chroot had been entered; if /X did not contain the
-  libc resolver fixtures (`/etc/resolv.conf`, `/etc/nsswitch.conf`,
-  `/etc/hosts`, NSS service modules) the lookup failed and the
-  connecting hostname was set to "UNKNOWN", causing hostname-based
-  deny rules to silently fail open.  IP-based ACLs are unaffected.
-  The per-module `use chroot` setting is unrelated to this issue.
-  The fix performs the lookup before entering the daemon chroot.
-  Reported by MegaManSec.
-
-- CVE-2026-43618 (CVSS v3.1 8.1, HIGH): Integer overflow in the
-  compressed-token decoder enabling remote memory disclosure to an
-  authenticated daemon peer.  The receiver accumulated a 32-bit
-  signed counter without overflow checking; a malicious sender could
-  trigger an overflow that, with careful manipulation, leaked process
-  memory contents to the attacker -- environment variables,
-  passwords, heap and library pointers -- significantly weakening
-  ASLR.  The fix bounds the counter and adds wire-input validation in
-  several adjacent places (defence-in-depth).  Workaround for older
-  releases: `refuse options = compress` in rsyncd.conf.  Reported by
-  Omar Elsayed.
-
-- CVE-2026-43619 (CVSS v3.1 6.3, MEDIUM): Symlink races on path-based
-  system calls in "use chroot = no" daemon mode (generalisation of
-  CVE-2026-29518).  Earlier fixes for symlink races on the receiver's
-  open() call missed the same race class on every other path-based
-  system call: chmod, lchown, utimes, rename, unlink, mkdir, symlink,
-  mknod, link, rmdir and lstat.  The fix routes each affected
-  path-based syscall through a parent dirfd opened under
-  RESOLVE_BENEATH-equivalent kernel-enforced confinement (openat2 on
-  Linux 5.6+, O_RESOLVE_BENEATH on FreeBSD 13+ and macOS 15+,
-  per-component O_NOFOLLOW walk elsewhere).  Default "use chroot =
-  yes" is not exposed.  Reported by Andrew Tridgell as a follow-on
-  audit of CVE-2026-29518.
-
-- CVE-2026-43620 (CVSS v3.1 6.5, MEDIUM): Out-of-bounds read in the
-  receiver's recv_files() enabling remote denial-of-service of any
-  client pulling from a malicious server (incomplete fix of commit
-  797e17f).  The earlier parent_ndx<0 guard added to send_files() was
-  not applied to the visually-identical block in recv_files().  A
-  malicious rsync server can drive any connecting client into a
-  deterministic SIGSEGV by setting CF_INC_RECURSE in the
-  compatibility flags and sending a crafted file list and transfer
-  record.  inc_recurse is the protocol-30+ default, so no special
-  options are required on the victim.  Workaround for older
-  releases: `--no-inc-recursive` on the client.  Reported by Pratham
-  Gupta.
-
-- CVE-2026-45232 (CVSS v3.1 3.1, LOW): Off-by-one out-of-bounds stack
-  write in the rsync client's HTTP CONNECT proxy handler
-  (`establish_proxy_connection()` in `socket.c`).  After issuing the
-  CONNECT request, rsync read the proxy's first response line one
-  byte at a time into a 1024-byte stack buffer with the bound
-  `cp < &buffer[sizeof buffer - 1]`.  If the proxy (or a MITM in
-  front of it) returned 1023+ bytes on that first line without a
-  newline terminator, `cp` exited the loop pointing at a buffer slot
-  the loop never wrote, leaving `*cp` holding stale stack data from
-  the earlier `snprintf()` of the outgoing CONNECT request.  The
-  post-loop logic then wrote a single `\0` one byte past the end of
-  the buffer on the stack.  Reach is client-side only, and only when
-  `RSYNC_PROXY` is set so rsync tunnels an `rsync://` connection
-  through an HTTP CONNECT proxy.  The written byte is always `\0`
-  and the offset is fixed by the buffer size, not attacker-chosen,
-  so this is not an arbitrary-write primitive: practical impact is
-  corruption of one adjacent stack byte and possible later
-  misbehaviour or crash.  The fix detects the "buffer filled without
-  finding `\n`" case explicitly by position and refuses the response
-  with "proxy response line too long".  Reported by Aisle Research
-  via Michal Ruprich (rsync-3.4.1-2.el10 QE).
-
-In addition to the six CVE fixes, this release adds defence-in-depth
-hardening on several adjacent paths: bounded wire-supplied counts and
-lengths in flist/io/acls/xattrs, a guard against length underflow in
-cumulative `snprintf()` callers, a parent block-index bounds check on
-the receiver, a NULL check in `read_delay_line()`, a lower ceiling on
-`MAX_WIRE_DEL_STAT` to avoid signed-int overflow in the
-`read_del_stats()` accumulator, rejection of hyphen-prefixed
-remote-shell hostnames (defence-in-depth against argv-injection in
-tooling that forwards untrusted input into the hostspec position;
-reported by Aisle Research via Michal Ruprich), and a NULL-check on
-`localtime_r()` in `timestring()` to keep a malicious server from
-crashing the client by advertising a file with an out-of-range
-modtime.
-
-### BUG FIXES:
-
-- Fixed a regression introduced by the 3.4.0 secure_relative_open()
-  CVE fix where legitimate directory symlinks on the receiver side
-  (e.g. when using `-K` / `--copy-dirlinks`) caused "failed
-  verification -- update discarded" errors on delta transfers. The
-  old code rejected every symlink in the path with a per-component
-  `O_NOFOLLOW` walk; the receiver now uses kernel-enforced "stay
-  below dirfd" path resolution where available. Fixes #715.
-
-### PORTABILITY / BUILD:
-
-- secure_relative_open() now uses `openat2(RESOLVE_BENEATH |
-  RESOLVE_NO_MAGICLINKS)` on Linux 5.6+, and `openat()` with
-  `O_RESOLVE_BENEATH` on FreeBSD 13+ and macOS 15+ (Sequoia) /
-  iOS 18+. The kernel rejects ".." escapes, absolute symlinks, and
-  symlinks whose target lies outside the starting directory, while
-  still following symlinks that resolve within it -- the same
-  trade-off that fixes the issue #715 regression without weakening
-  the original CVE protection. Other platforms (Solaris, OpenBSD,
-  NetBSD, Cygwin) retain the previous per-component `O_NOFOLLOW`
-  walk; on those platforms the issue #715 regression remains
-  visible.
-
-- testsuite/xattrs: ignore `SUNWattr_*` in the Solaris `xls`
-  helper.
-
-### DEVELOPER RELATED:
-
-- Added testsuite/symlink-dirlink-basis.test (taken from PR #864
-  by Samuel Henrique) covering the issue #715 regression and
-  several edge cases (`--backup`, `--inplace`, `--partial-dir`
-  with protocol < 29, top-level files). The test skips on
-  platforms without a RESOLVE_BENEATH equivalent.
-
-- Added regression tests for the new security fixes:
-  `chmod-symlink-race.test`, `chdir-symlink-race.test`,
-  `bare-do-open-symlink-race.test`, `alt-dest-symlink-race.test`,
-  `copy-dest-source-symlink.test`, `sender-flist-symlink-leak.test`,
-  `secure-relpath-validation.test`, `daemon-chroot-acl.test` and
-  `daemon-refuse-compress.test`. The symlink-race tests skip on
-  Cygwin, Solaris, OpenBSD and NetBSD (no RESOLVE_BENEATH
-  equivalent on those platforms).
-
-- runtests.py now errors early with a clear message when any of
-  the test helper programs (`tls`, `trimslash`, `t_unsafe`,
-  `t_chmod_secure`, `t_secure_relpath`, `wildtest`, `getgroups`,
-  `getfsdev`) are missing, instead of letting many tests fail with
-  confusing "not found" errors.
-
-- Added OpenBSD and NetBSD CI jobs that run `make check` on those
-  platforms.
-
-- Added Ubuntu 22.04 and AlmaLinux 8 CI workflows so future
-  backports to the two mainstream LTS families build and test on
-  the same CI surface as trunk.
-
-- testsuite/protected-regular.test now runs unprivileged via
-  `unshare` with user-namespace UID mapping, falling back to skip
-  if `unshare`/`uidmap` is not available; previously it required
-  real root.
-
-- Added `symlink-dirlink-basis` to the Cygwin CI's expected-skipped
-  list.
-
-- Removed the old release system (replaced by the new release
-  script in 3.4.2).

-# NEWS for rsync 3.4.2 (28 Apr 2026)
-
-## Changes in this version:
-
-### SECURITY RELATED:
-
-Several security-relevant defects were reported and fixed since 3.4.1.
-None were assigned a CVE — rsync's fork-per-connection design scopes
-the impact of each of these to the attacker's own connection, which is
-equivalent to the client closing the socket itself — but they are
-fixed here as a matter of hygiene and to reduce the chances of a
-future exploitable combination.  Many thanks to the external
-researchers who reported these issues.
-
-- Fixed a signed integer overflow in the PROXY protocol v2 header
-  parser: a negative `len` field could bypass the size check and cause
-  a stack buffer overflow in `read_buf()`.  Reported by John Walker of
-  ZeroPath.
-
-- Fixed an invalid access to the files array.  Reported by Calum
-  Hutton of Rapid7.
-
-- Reject negative token values in the compressed-stream token
-  decoder; a negative value could cause callers to misinterpret a
-  missing data pointer as literal data.  Reported by Will Sergeant.
-
-- Fixed the element count passed to the xattr `qsort()` (see
-  https://www.openwall.com/lists/oss-security/2026/04/16/2).
-
-- Fixed a buffer underflow in `clean_fname()`, and added a regression
-  test.
-
-- Fixed an uninitialized `mul_one` in the AVX2 get_checksum1 path
-  (undefined behaviour), and added a SIMD-checksum self-test that
-  cross-checks SSE2, SSSE3 and AVX2 against the C reference on both
-  aligned and unaligned buffers.
-
-- Fixed an uninitialized `buf1` on the first call to
-  `get_checksum2()` in the MD4 path (fixes #673).
-
-- Zero all new memory from internal allocations: `my_alloc()` now uses
-  `calloc`, and `expand_item_list()` zeros the expanded portion after
-  `realloc`.  This gives more predictable behaviour if stale or
-  uninitialised memory is ever accidentally read.
-
-### BUG FIXES:
-
-- Call `tzset()` before chroot so that log timestamps continue to
-  reflect the configured local timezone after the daemon chroots
-  (glibc needs `/etc/localtime`, which is unreachable post-chroot).
-
-- Use the correct time when writing to the log file.
-
-- Do not clear `DISPLAY` unconditionally.
-
-- Fixed a Y2038 bug in `syscall.c` by replacing the `Int32x32To64`
-  macro (which truncates its arguments to 32 bits) with a plain
-  64-bit multiplication.
-
-- Fixed ACL ID mapping for non-root users (closes #618).
-
-- Fixed handling of objects with many xattrs on FreeBSD.
-
-- Fixed `--open-noatime` not taking effect when opening regular
-  files: `O_NOATIME` is now also passed to `do_open_nofollow()`, which
-  has been used for regular files since the CVE fix "fixed symlink
-  race condition in sender".
-
-- Ignore "directory has vanished" errors.
-
-- Fixed the removal of multiple leading slashes.
-
-- Added the missing `--dirs` long option.
-
-- Fixed a segfault if `poptGetContext()` returns NULL (e.g. under
-  OOM) by not passing NULL to `poptReadDefaultConfig()`.  Reported by
-  Ronnie Sahlberg; found with `malloc-fail-tester`.
-
-- Fixed a build error on ia64 NonStop (which treats missing
-  prototypes as an error, not a warning).
-
-- Fixed a flaky hardlinks test (fixes #735).
-
-### ENHANCEMENTS:
-
-- Added multi-threaded `zstd` compression, gated by a new
-  `--compress-threads=N` option, with validation and man-page
-  coverage.
-
-- Documented the `temp dir` parameter in the rsyncd.conf man page
-  (fixes #820).
-
-- Improved rendering of interior dashes in long-option names in
-  `md-convert` (perhaps fixes #686).
-
-### PORTABILITY / BUILD:
-
-- Fixed glibc 2.43 const-preserving overloads of `strtok()`,
-  `strchr()` etc. by declaring the affected locals with the right
-  constness.  Contributed by Holger Hoffstätte.
-
-- Converted the bundled zlib 1.2.8 from K&R-style function
-  definitions to ANSI prototypes, so it builds with clang 16+.
-
-- Avoid using `bool` as an identifier; it is a keyword in C23.
-
-- `configure.ac`: check for xattr functions in libc first and only
-  fall back to `-lattr`, avoiding spurious overlinking when `-lattr`
-  happens to be installed.  Contributed by Eli Schwartz.
-
-- Made the build reproducible by honouring `SOURCE_DATE_EPOCH` for
-  the manpage date.
-
-- Removed obsolete `popt/findme.c` and `popt/findme.h` that upstream
-  popt 1.14 folded into `popt.c` (fixes #710).  Contributed by Alan
-  Coopersmith.
-
-### INTERNAL:
-
-- Made many module-global variables `const` so they can live in
-  `.rodata` and enable additional compiler optimization.
-
-### DEVELOPER RELATED:
-
-- Replaced `runtests.sh` with `runtests.py`, a Python test runner
-  that supports `--valgrind` (with per-process log files so valgrind
-  output no longer interferes with output comparisons) and
-  `-j/--parallel` execution for roughly a 7× speed-up on typical
-  hardware.
-
-- Added a SIMD checksum self-test and a `clean-fname-underflow`
-  regression test.
-
-- Various CI fixes for macOS and Cygwin (including adding
-  `simd-checksum` to the expected-skipped lists on platforms without
-  SIMD), and tests now run on `ubuntu-latest`.
-
-- removed support for the unmaintained rsync-patches archive

- * Android-specific helpers.
- *
- * openat2() usability probe
- * -------------------------
- * openat2(2) is invoked directly via syscall() because the C library lacked a
- * wrapper for it for years.  Under a seccomp filter that uses
- * SECCOMP_RET_TRAP -- as the Android application sandbox does -- a disallowed
- * syscall raises SIGSYS and *kills the process* rather than failing with
- * ENOSYS, so inspecting errno after the call is too late.  We therefore probe
- * openat2() once, behind a temporary SIGSYS handler, so a trapped syscall is
- * caught and secure_relative_open_linux() can fall back to the portable
- * per-component O_NOFOLLOW resolver instead of the whole process dying.
- *
- * This is only needed on Android, so the probe body is compiled only there.
- * __ANDROID__ is defined by Bionic's headers and reflects the *target*, not
- * the build host: it is set both for NDK cross-compiles (from a Linux/macOS
- * host) and for native Termux builds, and is unset on every other platform.
- * That makes it a reliable compile-time switch for cross builds -- there is
- * nothing to detect in configure.  Everywhere else openat2() is never
- * seccomp-trapped to SIGSYS (a missing syscall simply returns ENOSYS), so
- * openat2_usable() collapses to a constant 1 with no run-time cost.

+
+# rsync top-level test script -- this invokes all the other more
+# detailed tests in order.  This script can either be called by `make
+# check' or `make installcheck'.  `check' runs against the copies of
+# the program and other files in the build directory, and
+# `installcheck' against the installed copy of the program.
+
+# It can also be called on a single test file using a run like this:
+#
+#  preserve_scratch=yes whichtests=itemize.test ./runtests.sh
+
+# In either case we need to also be able to find the source directory,
+# since we read test scripts and possibly other information from
+# there.
+
+# Whenever possible, informational messages are written to stdout and
+# error messages to stderr.  They're separated out by the build farm
+# display scripts.
+
+# According to the GNU autoconf manual, the only valid place to set up
+# directory locations is through Make, since users are allowed to (try
+# to) change their mind on the Make command line.  So, Make has to
+# pass in all the values we need.
+
+# For other configured settings we read ./config.sh, which tells us
+# about shell commands on this machine and similar things.
+
+# rsync_bin gives the location of the rsync binary.  This is either
+# builddir/rsync if we're testing an uninstalled copy, or
+# install_prefix/bin/rsync if we're testing an installed copy.  On the
+# build farm rsync will be installed, but into a scratch /usr.
+
+# srcdir gives the location of the source tree, which lets us find the
+# build scripts.  At the moment we assume we are invoked from the
+# source directory.
+
+# This script must be invoked from the build directory.
+
+# A scratch directory, 'testtmp', is used in the build directory to
+# hold per-test subdirectories.
+
+# This script also uses the $loglevel environment variable.  1 is the
+# default value, and 10 the most verbose.  You can set this from the
+# Make command line.  It's also set by the build farm to give more
+# detail for failing builds.
+
+# -------------------------------------------------------------------------
+
+# NOTES FOR TEST CASES:
+
+# Each test case runs in its own shell.
+
+# Exit codes from tests:
+
+#    1  tests failed
+#    2  error in starting tests
+#   77  this test skipped (random value unlikely to happen by chance, same as
+#       automake)
+
+# HOWEVER, the overall exit code to the farm is different: we return
+# the *number of tests that failed*, so that it will show up nicely in
+# the overall summary.
+
+# rsync.fns contains some general setup functions and definitions.
+
+# -------------------------------------------------------------------------
+
+# NOTES ON PORTABILITY:
+
+# Both this script and the Makefile have to be pretty conservative
+# about which Unix features they use.
+
+# We cannot count on Make exporting variables to commands, unless
+# they're explicitly given on the command line.
+
+# Also, we can't count on 'cp -a' or 'mkdir -p', although they're
+# pretty handy (see function makepath for the latter).
+
+# I think some of the GNU documentation suggests that we shouldn't
+# rely on shell functions.  However, the Bash manual seems to say that
+# they're in POSIX 1003.2, and since the build farm relies on them
+# they're probably working on most machines we really care about.
+
+# You cannot use "function foo {" syntax, but must instead say "foo()
+# {", or it breaks on FreeBSD.
+
+# BSD machines tend not to have "head" or "seq".
+
+# You cannot do "export VAR=VALUE" all on one line; the export must be
+# separate from the assignment.  (SCO SysV)
+
+# Don't rely on grep -q, as that doesn't work everywhere -- just redirect
+# stdout to /dev/null to keep it quiet.
+
+# -------------------------------------------------------------------------
+
+# STILL TO DO:
+
+# We need a good protection against tests that hang indefinitely.
+# Perhaps some combination of starting them in the background, wait,
+# and kill?
+
+# Perhaps we need a common way to cleanup tests.  At the moment just
+# clobbering the directory when we're done should be enough.
+
+# If any of the targets fail, then (GNU?) Make returns 2, instead of
+# the return code from the failing command.  This is fine, but it
+# means that the build farm just shows "2" for failed tests, not the
+# number of tests that actually failed.  For more details we might
+# need to grovel through the log files to find a line saying how many
+# failed.

-# Test that updating a file through a directory symlink works when using
-# -K (--copy-dirlinks). This is a regression test for:
-#   https://github.com/RsyncProject/rsync/issues/715
-#
-# The CVE fix in commit c35e283 introduced secure_relative_open() which
-# uses O_NOFOLLOW on all path components, breaking legitimate directory
-# symlinks on the receiver side. The fix splits the path into basedir
-# (dirname, symlinks followed) and basename (O_NOFOLLOW) so that
-# directory symlinks are traversed while the final file component is
-# still protected.
-#
-# The regression only manifests when delta matching is triggered (i.e.,
-# the sender finds matching blocks in the old file). Small files with
-# completely different content are transferred in full and don't trigger
-# the bug. We use a large file with a small modification to ensure
-# delta transfer is used.
-#
-# In addition to the original regression, this test covers edge cases
-# in the fix itself:
-#   - --backup with directory symlinks (finish_transfer pointer identity)
-#   - --partial-dir with protocol < 29 (fnamecmp != partialptr guard)
-#   - --inplace with directory symlinks (updating_basis_or_equiv check)
-#   - Files without a dirname (top-level files, no split needed)
