verify-patch-sanity.py validates every active recipe .patch has internally- consistent hunk line counts — catching the 'malformed patch at line N' failure at commit/CI/preflight time instead of hours into a cook. This cycle hit that class three times (qtwaylandscanner, sddm, xwayland), each only discovered when cookbook tried to apply the patch. Running it across the repo found 29 latent malformed patches (validated against GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22'). They were harmless only because they sit in vendored recipes (baked, not re- applied) — but would fail on any version-bump re-derivation. --fix recounts the hunk headers (body untouched) and repaired all 29. Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test (test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats (empty placeholders, bare-@@ git hunks).

.. program:: llvm-strings
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-strings` [*options*] [*input...*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
:program:`llvm-strings` is a tool intended as a drop-in replacement for GNU's
|
|
:program:`strings`, which looks for printable strings in files and writes them
|
|
to the standard output stream. A printable string is any sequence of four (by
|
|
default) or more printable ASCII characters. The end of the file, or any other
|
|
byte, terminates the current sequence.
|
|
|
|
:program:`llvm-strings` looks for strings in each ``input`` file specified.
|
|
Unlike GNU :program:`strings` it looks in the entire input file, regardless of
|
|
file format, rather than restricting the search to certain sections of object
|
|
files. If "``-``" is specified as an ``input``, or no ``input`` is specified,
|
|
the program reads from the standard input stream.
|
|
|
|
EXAMPLE
|
|
-------
|
|
|
|
.. code-block:: console
|
|
|
|
$ cat input.txt
|
|
bars
|
|
foo
|
|
wibble blob
|
|
$ llvm-strings input.txt
|
|
bars
|
|
wibble blob
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
.. option:: --all, -a
|
|
|
|
Silently ignored. Present for GNU :program:`strings` compatibility.
|
|
|
|
.. option:: --bytes=<length>, -n
|
|
|
|
Set the minimum number of printable ASCII characters required for a sequence of
|
|
bytes to be considered a string. The default value is 4.
|
|
|
|
.. option:: --help, -h
|
|
|
|
Display a summary of command line options.
|
|
|
|
.. option:: --print-file-name, -f
|
|
|
|
Display the name of the containing file before each string.
|
|
|
|
Example:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-strings --print-file-name test.o test.elf
|
|
test.o: _Z5hellov
|
|
test.o: some_bss
|
|
test.o: test.cpp
|
|
test.o: main
|
|
test.elf: test.cpp
|
|
test.elf: test2.cpp
|
|
test.elf: _Z5hellov
|
|
test.elf: main
|
|
test.elf: some_bss
|
|
|
|
.. option:: --radix=<radix>, -t
|
|
|
|
Display the offset within the file of each string, before the string and using
|
|
the specified radix. Valid ``<radix>`` values are ``o``, ``d`` and ``x`` for
|
|
octal, decimal and hexadecimal respectively.
|
|
|
|
Example:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-strings --radix=o test.o
|
|
1054 _Z5hellov

|
|
|
|
.. option:: --version
|
|
|
|
Display the version of the :program:`llvm-strings` executable.
|
|
|
|
.. option:: @<FILE>
|
|
|
|
Read command-line options from response file ``<FILE>``.
|
|
|
|
EXIT STATUS
|
|
-----------
