SPDX-License-Identifier: CC-BY-SA-2.0-UK + +***************************** +QA Error and Warning Messages +***************************** + +.. _qa-introduction: + +Introduction +============ + +When building a recipe, the OpenEmbedded build system performs various +QA checks on the output to ensure that common issues are detected and +reported. Sometimes when you create a new recipe to build new software, +it will build with no problems. When this is not the case, or when you +have QA issues building any software, it could take a little time to +resolve them. + +While it is tempting to ignore a QA message or even to disable QA +checks, it is best to try and resolve any reported QA issues. This +chapter provides a list of the QA messages and brief explanations of the +issues you could encounter so that you can properly resolve problems. + +The next section provides a list of all QA error and warning messages +based on a default configuration. Each entry provides the message or +error form along with an explanation. + +.. note:: + + - At the end of each message, the name of the associated QA test (as + listed in the ":ref:`insane.bbclass <ref-classes-insane>`" + section) appears within square brackets. + + - As mentioned, this list of error and warning messages is for QA + checks only. The list does not cover all possible build errors or + warnings you could encounter. + + - Because some QA checks are disabled by default, this list does not + include all possible QA check errors and warnings. + +.. _qa-errors-and-warnings: + +Errors and Warnings +=================== + +.. _qa-check-libexec: + +- ``<packagename>: <path> is using libexec please relocate to <libexecdir> [libexec]`` + + The specified package contains files in ``/usr/libexec`` when the + distro configuration uses a different path for ``<libexecdir>`` By + default, ``<libexecdir>`` is ``$prefix/libexec``. However, this + default can be changed (e.g. ``${libdir}``). + + +.. _qa-check-rpaths: + +- ``package <packagename> contains bad RPATH <rpath> in file <file> [rpaths]`` + + The specified binary produced by the recipe contains dynamic library + load paths (rpaths) that contain build system paths such as + :term:`TMPDIR`, which are incorrect for the target and + could potentially be a security issue. Check for bad ``-rpath`` + options being passed to the linker in your + :ref:`ref-tasks-compile` log. Depending on the build + system used by the software being built, there might be a configure + option to disable rpath usage completely within the build of the + software. + + +.. _qa-check-useless-rpaths: + +- ``<packagename>: <file> contains probably-redundant RPATH <rpath> [useless-rpaths]`` + + The specified binary produced by the recipe contains dynamic library + load paths (rpaths) that on a standard system are searched by default + by the linker (e.g. ``/lib`` and ``/usr/lib``). While these paths + will not cause any breakage, they do waste space and are unnecessary. + Depending on the build system used by the software being built, there + might be a configure option to disable rpath usage completely within + the build of the software. + + +.. _qa-check-file-rdeps: + +- ``<packagename> requires <files>, but no providers in its RDEPENDS [file-rdeps]`` + + A file-level dependency has been identified from the specified + package on the specified files, but there is no explicit + corresponding entry in :term:`RDEPENDS`. If + particular files are required at runtime then ``RDEPENDS`` should be + declared in the recipe to ensure the packages providing them are + built. + + +.. _qa-check-build-deps: + +- ``<packagename1> rdepends on <packagename2>, but it isn't a build dependency? [build-deps]`` + + A runtime dependency exists between the two specified packages, but + there is nothing explicit within the recipe to enable the + OpenEmbedded build system to ensure that dependency is satisfied. + This condition is usually triggered by an + :term:`RDEPENDS` value being added at the packaging + stage rather than up front, which is usually automatic based on the + contents of the package. In most cases, you should change the recipe + to add an explicit ``RDEPENDS`` for the dependency. + + +.. _qa-check-dev-so: + +- ``non -dev/-dbg/nativesdk- package contains symlink .so: <packagename> path '<path>' [dev-so]`` + + Symlink ``.so`` files are for development only, and should therefore + go into the ``-dev`` package. This situation might occur if you add + ``*.so*`` rather than ``*.so.*`` to a non-dev package. Change + :term:`FILES` (and possibly + :term:`PACKAGES`) such that the specified ``.so`` + file goes into an appropriate ``-dev`` package. + + +.. _qa-check-staticdev: + +- ``non -staticdev package contains static .a library: <packagename> path '<path>' [staticdev]`` + + Static ``.a`` library files should go into a ``-staticdev`` package. + Change :term:`FILES` (and possibly + :term:`PACKAGES`) such that the specified ``.a`` file + goes into an appropriate ``-staticdev`` package. + + +.. _qa-check-libdir: + +- ``<packagename>: found library in wrong location [libdir]`` + + The specified file may have been installed into an incorrect + (possibly hardcoded) installation path. For example, this test will + catch recipes that install ``/lib/bar.so`` when ``${base_libdir}`` is + "lib32". Another example is when recipes install + ``/usr/lib64/foo.so`` when ``${libdir}`` is "/usr/lib". False + positives occasionally exist. For these cases add "libdir" to + :term:`INSANE_SKIP` for the package. + + +.. _qa-check-debug-files: + +- ``non debug package contains .debug directory: <packagename> path <path> [debug-files]`` + + The specified package contains a ``.debug`` directory, which should + not appear in anything but the ``-dbg`` package. This situation might + occur if you add a path which contains a ``.debug`` directory and do + not explicitly add the ``.debug`` directory to the ``-dbg`` package. + If this is the case, add the ``.debug`` directory explicitly to + ``FILES_${PN}-dbg``. See :term:`FILES` for additional + information on ``FILES``. + + +.. _qa-check-arch: + +- ``Architecture did not match (<file_arch>, expected <machine_arch>) in <file> [arch]`` + + By default, the OpenEmbedded build system checks the Executable and + Linkable Format (ELF) type, bit size, and endianness of any binaries + to ensure they match the target architecture. This test fails if any + binaries do not match the type since there would be an + incompatibility. The test could indicate that the wrong compiler or + compiler options have been used. Sometimes software, like + bootloaders, might need to bypass this check. If the file you receive + the error for is firmware that is not intended to be executed within + the target operating system or is intended to run on a separate + processor within the device, you can add "arch" to + :term:`INSANE_SKIP` for the package. Another + option is to check the :ref:`ref-tasks-compile` log + and verify that the compiler options being used are correct. + + + +- ``Bit size did not match (<file_bits>, expected <machine_bits>) in <file> [arch]`` + + By default, the OpenEmbedded build system checks the Executable and + Linkable Format (ELF) type, bit size, and endianness of any binaries + to ensure they match the target architecture. This test fails if any + binaries do not match the type since there would be an + incompatibility. The test could indicate that the wrong compiler or + compiler options have been used. Sometimes software, like + bootloaders, might need to bypass this check. If the file you receive + the error for is firmware that is not intended to be executed within + the target operating system or is intended to run on a separate + processor within the device, you can add "arch" to + :term:`INSANE_SKIP` for the package. Another + option is to check the :ref:`ref-tasks-compile` log + and verify that the compiler options being used are correct. + + + +- ``Endianness did not match (<file_endianness>, expected <machine_endianness>) in <file> [arch]`` + + By default, the OpenEmbedded build system checks the Executable and + Linkable Format (ELF) type, bit size, and endianness of any binaries + to ensure they match the target architecture.

If the file you receive + the error for is firmware that is not intended to be executed within + the target operating system or is intended to run on a separate + processor within the device, you can add "arch" to + :term:`INSANE_SKIP` for the package. Another + option is to check the :ref:`ref-tasks-compile` log + and verify that the compiler options being used are correct. + + +.. _qa-check-textrel: + +- ``ELF binary '<file>' has relocations in .text [textrel]`` + + The specified ELF binary contains relocations in its ``.text`` + sections. This situation can result in a performance impact at + runtime. + + Typically, the way to solve this performance issue is to add "-fPIC" + or "-fpic" to the compiler command-line options. For example, given + software that reads :term:`CFLAGS` when you build it, + you could add the following to your recipe: + :: + + CFLAGS_append = " -fPIC " + + For more information on text relocations at runtime, see + http://www.akkadia.org/drepper/textrelocs.html. + + +.. _qa-check-ldflags: + +- ``File '<file>' in package '<package>' doesn't have GNU_HASH (didn't pass LDFLAGS?) [ldflags]`` + + This indicates that binaries produced when building the recipe have + not been linked with the :term:`LDFLAGS` options + provided by the build system. Check to be sure that the ``LDFLAGS`` + variable is being passed to the linker command. A common workaround + for this situation is to pass in ``LDFLAGS`` using + :term:`TARGET_CC_ARCH` within the recipe as + follows: + :: + + TARGET_CC_ARCH += "${LDFLAGS}" + + +.. _qa-check-xorg-driver-abi: + +- ``Package <packagename> contains Xorg driver (<driver>) but no xorg-abi- dependencies [xorg-driver-abi]`` + + The specified package contains an Xorg driver, but does not have a + corresponding ABI package dependency. The xserver-xorg recipe + provides driver ABI names. All drivers should depend on the ABI + versions that they have been built against. Driver recipes that + include ``xorg-driver-input.inc`` or ``xorg-driver-video.inc`` will + automatically get these versions. Consequently, you should only need + to explicitly add dependencies to binary driver recipes. + + +.. _qa-check-infodir: + +- ``The /usr/share/info/dir file is not meant to be shipped in a particular package. [infodir]`` + + The ``/usr/share/info/dir`` should not be packaged. Add the following + line to your :ref:`ref-tasks-install` task or to your + ``do_install_append`` within the recipe as follows: + :: + + rm ${D}${infodir}/dir + + +.. _qa-check-symlink-to-sysroot: + +- ``Symlink <path> in <packagename> points to TMPDIR [symlink-to-sysroot]`` + + The specified symlink points into :term:`TMPDIR` on the + host. Such symlinks will work on the host. However, they are clearly + invalid when running on the target. You should either correct the + symlink to use a relative path or remove the symlink. + + +.. _qa-check-la: + +- ``<file> failed sanity test (workdir) in path <path> [la]`` + + The specified ``.la`` file contains :term:`TMPDIR` + paths. Any ``.la`` file containing these paths is incorrect since + ``libtool`` adds the correct sysroot prefix when using the files + automatically itself. + + +.. _qa-check-pkgconfig: + +- ``<file> failed sanity test (tmpdir) in path <path> [pkgconfig]`` + + The specified ``.pc`` file contains + :term:`TMPDIR`\ ``/``\ :term:`WORKDIR` + paths. Any ``.pc`` file containing these paths is incorrect since + ``pkg-config`` itself adds the correct sysroot prefix when the files + are accessed. + + +.. _qa-check-debug-deps: + +- ``<packagename> rdepends on <debug_packagename> [debug-deps]`` + + A dependency exists between the specified non-dbg package (i.e. a + package whose name does not end in ``-dbg``) and a package that is a + ``dbg`` package. The ``dbg`` packages contain debug symbols and are + brought in using several different methods: + + - Using the ``dbg-pkgs`` + :term:`IMAGE_FEATURES` value. + + - Using :term:`IMAGE_INSTALL`. + + - As a dependency of another ``dbg`` package that was brought in + using one of the above methods. + + The dependency might have been automatically added because the + ``dbg`` package erroneously contains files that it should not contain + (e.g. a non-symlink ``.so`` file) or it might have been added + manually (e.g. by adding to :term:`RDEPENDS`). + + +.. _qa-check-dev-deps: + +- ``<packagename> rdepends on <dev_packagename> [dev-deps]`` + + A dependency exists between the specified non-dev package (a package + whose name does not end in ``-dev``) and a package that is a ``dev`` + package. The ``dev`` packages contain development headers and are + usually brought in using several different methods: + + - Using the ``dev-pkgs`` + :term:`IMAGE_FEATURES` value. + + - Using :term:`IMAGE_INSTALL`. + + - As a dependency of another ``dev`` package that was brought in + using one of the above methods. + + The dependency might have been automatically added (because the + ``dev`` package erroneously contains files that it should not have + (e.g. a non-symlink ``.so`` file) or it might have been added + manually (e.g. by adding to :term:`RDEPENDS`). + + +.. _qa-check-dep-cmp: + +- ``<var>_<packagename> is invalid: <comparison> (<value>) only comparisons <, =, >, <=, and >= are allowed [dep-cmp]`` + + If you are adding a versioned dependency relationship to one of the + dependency variables (:term:`RDEPENDS`, + :term:`RRECOMMENDS`, + :term:`RSUGGESTS`, + :term:`RPROVIDES`, + :term:`RREPLACES`, or + :term:`RCONFLICTS`), you must only use the named + comparison operators. Change the versioned dependency values you are + adding to match those listed in the message. + + +.. _qa-check-compile-host-path: + +- ``<recipename>: The compile log indicates that host include and/or library paths were used. Please check the log '<logfile>' for more information. [compile-host-path]`` + + The log for the :ref:`ref-tasks-compile` task + indicates that paths on the host were searched for files, which is + not appropriate when cross-compiling. Look for "is unsafe for + cross-compilation" or "CROSS COMPILE Badness" in the specified log + file. + + +.. _qa-check-install-host-path: + +- ``<recipename>: The install log indicates that host include and/or library paths were used. Please check the log '<logfile>' for more information. [install-host-path]`` + + The log for the :ref:`ref-tasks-install` task + indicates that paths on the host were searched for files, which is + not appropriate when cross-compiling. Look for "is unsafe for + cross-compilation" or "CROSS COMPILE Badness" in the specified log + file. + + +.. _qa-check-configure-unsafe: + +- ``This autoconf log indicates errors, it looked at host include and/or library paths while determining system capabilities. Rerun configure task after fixing this. [configure-unsafe]`` + + The log for the :ref:`ref-tasks-configure` task + indicates that paths on the host were searched for files, which is + not appropriate when cross-compiling. Look for "is unsafe for + cross-compilation" or "CROSS COMPILE Badness" in the specified log + file. + + +.. _qa-check-pkgname: + +- ``<packagename> doesn't match the [a-z0-9.+-]+ regex [pkgname]`` + + The convention within the OpenEmbedded build system (sometimes + enforced by the package manager itself) is to require that package + names are all lower case and to allow a restricted set of characters. + If your recipe name does not match this, or you add packages to + :term:`PACKAGES` that do not conform to the + convention, then you will receive this error. Rename your recipe. Or, + if you have added a non-conforming package name to ``PACKAGES``, + change the package name appropriately. + + +.. _qa-check-unknown-configure-option: + +- ``<recipe>: configure was passed unrecognized options: <options> [unknown-configure-option]`` + + The configure script is reporting that the specified options are + unrecognized. This situation could be because the options were + previously valid but have been removed from the configure script. Or, + there was a mistake when the options were added and there is another + option that should be used instead. If you are unsure, consult the + upstream build documentation, the ``./configure --help`` output, and + the upstream change log or release notes. Once you have worked out + what the appropriate change is, you can update + :term:`EXTRA_OECONF`, + :term:`PACKAGECONFIG_CONFARGS`, or the + individual :term:`PACKAGECONFIG` option values + accordingly. + + +.. _qa-check-pn-overrides: + +- ``Recipe <recipefile> has PN of "<recipename>" which is in OVERRIDES, this can result in unexpected behavior. [pn-overrides]`` + + The specified recipe has a name (:term:`PN`) value that + appears in :term:`OVERRIDES`. If a recipe is named + such that its ``PN`` value matches something already in ``OVERRIDES`` + (e.g. ``PN`` happens to be the same as :term:`MACHINE` + or :term:`DISTRO`), it can have unexpected + consequences. For example, assignments such as + ``FILES_${PN} = "xyz"`` effectively turn into ``FILES = "xyz"``. + Rename your recipe (or if ``PN`` is being set explicitly, change the + ``PN`` value) so that the conflict does not occur. See + :term:`FILES` for additional information. + + +.. _qa-check-pkgvarcheck: + +- ``<recipefile>: Variable <variable> is set as not being package specific, please fix this. [pkgvarcheck]`` + + Certain variables (:term:`RDEPENDS`, + :term:`RRECOMMENDS`, + :term:`RSUGGESTS`, + :term:`RCONFLICTS`, + :term:`RPROVIDES`, + :term:`RREPLACES`, :term:`FILES`, + ``pkg_preinst``, ``pkg_postinst``, ``pkg_prerm``, ``pkg_postrm``, and + :term:`ALLOW_EMPTY`) should always be set specific + to a package (i.e. they should be set with a package name override + such as ``RDEPENDS_${PN} = "value"`` rather than + ``RDEPENDS = "value"``). If you receive this error, correct any + assignments to these variables within your recipe. + + +- ``recipe uses DEPENDS_${PN}, should use DEPENDS [pkgvarcheck]`` + + This check looks for instances of setting ``DEPENDS_${PN}`` + which is erroneous (:term:`DEPENDS` is a recipe-wide variable and thus + it is not correct to specify it for a particular package, nor will such + an assignment actually work.) Set ``DEPENDS`` instead. + + +.. _qa-check-already-stripped: + +- ``File '<file>' from <recipename> was already stripped, this will prevent future debugging! [already-stripped]`` + + Produced binaries have already been stripped prior to the build + system extracting debug symbols. It is common for upstream software + projects to default to stripping debug symbols for output binaries. + In order for debugging to work on the target using ``-dbg`` packages, + this stripping must be disabled. + + Depending on the build system used by the software being built, + disabling this stripping could be as easy as specifying an additional + configure option. If not, disabling stripping might involve patching + the build scripts. In the latter case, look for references to "strip" + or "STRIP", or the "-s" or "-S" command-line options being specified + on the linker command line (possibly through the compiler command + line if preceded with "-Wl,"). + + .. note:: + + Disabling stripping here does not mean that the final packaged + binaries will be unstripped. Once the OpenEmbedded build system + splits out debug symbols to the ``-dbg`` package, it will then + strip the symbols from the binaries. + + +.. _qa-check-packages-list: + +- ``<packagename> is listed in PACKAGES multiple times, this leads to packaging errors. [packages-list]`` + + Package names must appear only once in the + :term:`PACKAGES` variable. You might receive this + error if you are attempting to add a package to ``PACKAGES`` that is + already in the variable's value. + + +.. _qa-check-files-invalid: + +- ``FILES variable for package <packagename> contains '//' which is invalid. Attempting to fix this but you should correct the metadata. [files-invalid]`` + + The string "//" is invalid in a Unix path. Correct all occurrences + where this string appears in a :term:`FILES` variable so + that there is only a single "/". + + +.. _qa-check-installed-vs-shipped: + +- ``<recipename>: Files/directories were installed but not shipped in any package [installed-vs-shipped]`` + + Files have been installed within the + :ref:`ref-tasks-install` task but have not been + included in any package by way of the :term:`FILES` + variable. Files that do not appear in any package cannot be present + in an image later on in the build process. You need to do one of the + following: + + - Add the files to ``FILES`` for the package you want them to appear + in (e.g. ``FILES_${``\ :term:`PN`\ ``}`` for the main + package). + + - Delete the files at the end of the ``do_install`` task if the + files are not needed in any package. + + + +- ``<oldpackage>-<oldpkgversion> was registered as shlib provider for <library>, changing it to <newpackage>-<newpkgversion> because it was built later`` + + This message means that both ``<oldpackage>`` and ``<newpackage>`` + provide the specified shared library. You can expect this message + when a recipe has been renamed. However, if that is not the case, the + message might indicate that a private version of a library is being + erroneously picked up as the provider for a common library. If that + is the case, you should add the library's ``.so`` file name to + :term:`PRIVATE_LIBS` in the recipe that provides + the private version of the library. + + +.. _qa-check-unlisted-pkg-lics: + +- ``LICENSE_<packagename> includes licenses (<licenses>) that are not listed in LICENSE [unlisted-pkg-lics]`` + + The :term:`LICENSE` of the recipe should be a superset + of all the licenses of all packages produced by this recipe. In other + words, any license in ``LICENSE_*`` should also appear in + :term:`LICENSE`. + + +.. _qa-check-configure-gettext: + +- ``AM_GNU_GETTEXT used but no inherit gettext [configure-gettext]`` + + If a recipe is building something that uses automake and the automake + files contain an ``AM_GNU_GETTEXT`` directive then this check will fail + if there is no ``inherit gettext`` statement in the recipe to ensure + that gettext is available during the build. Add ``inherit gettext`` to + remove the warning. + + +.. _qa-check-mime: + +- ``package contains mime types but does not inherit mime: <packagename> path '<file>' [mime]`` + + The specified package contains mime type files (``.xml`` files in + ``${datadir}/mime/packages``) and yet does not inherit the mime + class which will ensure that these get properly installed. Either + add ``inherit mime`` to the recipe or remove the files at the + ``do_install`` step if they are not needed. + + +.. _qa-check-mime-xdg: + +- ``package contains desktop file with key 'MimeType' but does not inhert mime-xdg: <packagename> path '<file>' [mime-xdg]`` + + The specified package contains a .desktop file with a 'MimeType' key + present, but does not inherit the mime-xdg class that is required in + order for that to be activated. Either add ``inherit mime`` to the + recipe or remove the files at the ``do_install`` step if they are not + needed. + + +.. _qa-check-src-uri-bad: + +- ``<recipename>: SRC_URI uses unstable GitHub archives [src-uri-bad]`` + + GitHub provides "archive" tarballs, however these can be re-generated + on the fly and thus the file's signature will not necessarily match that + in the SRC_URI checksums in future leading to build failures. It is + recommended that you use an official release tarball or switch to + pulling the corresponding revision in the actual git repository instead. + + +- ``SRC_URI uses PN not BPN [src-uri-bad]`` + + If some part of :term:`SRC_URI` needs to reference the recipe name, it should do + so using ${:term:`BPN`} rather than ${:term:`PN`} as the latter will change + for different variants of the same recipe e.g. when :term:`BBCLASSEXTEND` + or multilib are being used. This check will fail if a reference to ``${PN}`` + is found within the ``SRC_URI`` value - change it to ``${BPN}`` instead. + + +.. _qa-check-unhandled-features-check: + +- ``<recipename>: recipe doesn't inherit features_check [unhandled-features-check]`` + + This check ensures that if one of the variables that the :ref:`features_check <ref-classes-features_check>` + class supports (e.g. :term:`REQUIRED_DISTRO_FEATURES`) is used, then the recipe + inherits ``features_check`` in order for the requirement to actually work. If + you are seeing this message, either add ``inherit features_check`` to your recipe + or remove the reference to the variable if it is not needed. + + +.. _qa-check-missing-update-alternatives: + +- ``<recipename>: recipe defines ALTERNATIVE_<packagename> but doesn't inherit update-alternatives. This might fail during do_rootfs later! [missing-update-alternatives]`` + + This check ensures that if a recipe sets the :term:`ALTERNATIVE` variable that the + recipe also inherits :ref:`update-alternatives <ref-classes-update-alternatives>` such + that the alternative will be correctly set up. If you are seeing this message, either + add ``inherit update-alternatives`` to your recipe or remove the reference to the variable + if it is not needed. + + +.. _qa-check-shebang-size: + +- ``<packagename>: <file> maximum shebang size exceeded, the maximum size is 128. [shebang-size]`` + + This check ensures that the shebang line (``#!`` in the first line) for a script + is not longer than 128 characters, which can cause an error at runtime depending + on the operating system. If you are seeing this message then the specified script + may need to be patched to have a shorter in order to avoid runtime problems. + + +.. _qa-check-perllocalpod: + +- ``<packagename> contains perllocal.pod (<files>), should not be installed [perllocalpod]`` + + ``perllocal.pod`` is an index file of locally installed modules and so shouldn't be + installed by any distribution packages. The :ref:`cpan <ref-classes-cpan>` class + already sets ``NO_PERLLOCAL`` to stop this file being generated by most Perl recipes, + but if a recipe is using ``MakeMaker`` directly then they might not be doing this + correctly. This check ensures that perllocal.pod is not in any package in order to + avoid multiple packages shipping this file and thus their packages conflicting + if installed together. + + +.. _qa-check-usrmerge: + +- ``<packagename> package is not obeying usrmerge distro feature. /<path> should be relocated to /usr. [usrmerge]`` + + If ``usrmerge`` is in :term:`DISTRO_FEATURES`, this check will ensure that no package + installs files to root (``/bin``, ``/sbin``, ``/lib``, ``/lib64``) directories. If you are seeing this + message, it indicates that the ``do_install`` step (or perhaps the build process that + ``do_install`` is calling into, e.g. ``make install`` is using hardcoded paths instead + of the variables set up for this (``bindir``, ``sbindir``, etc.), and should be + changed so that it does. + + +.. _qa-check-patch-fuzz: + +- ``Fuzz detected: <patch output> [patch-fuzz]`` + + This check looks for evidence of "fuzz" when applying patches within the ``do_patch`` + task. Patch fuzz is a situation when the ``patch`` tool ignores some of the context + lines in order to apply the patch. Consider this example: + + Patch to be applied: :: + + --- filename + +++ filename + context line 1 + context line 2 + context line 3 + +newly added line + context line 4 + context line 5 + context line 6 + + Original source code: :: + + different context line 1 + different context line 2 + context line 3 + context line 4 + different context line 5 + different context line 6 + + Outcome (after applying patch with fuzz): :: + + different context line 1 + different context line 2 + context line 3 + newly added line + context line 4 + different context line 5 + different context line 6 + + Chances are, the newly added line was actually added in a completely + wrong location, or it was already in the original source and was added + for the second time. This is especially possible if the context line 3 + and 4 are blank or have only generic things in them, such as ``#endif`` or ``}``. + Depending on the patched code, it is entirely possible for an incorrectly + patched file to still compile without errors. + + *How to eliminate patch fuzz warnings* + + Use the ``devtool`` command as explained by the warning. First, unpack the + source into devtool workspace: :: + + devtool modify <recipe> + + This will apply all of the patches, and create new commits out of them in + the workspace - with the patch context updated. + + Then, replace the patches in the recipe layer: :: + + devtool finish --force-patch-refresh <recipe> <layer_path> + + The patch updates then need be reviewed (preferably with a side-by-side diff + tool) to ensure they are indeed doing the right thing i.e.: + + #. they are applied in the correct location within the file; + #. they do not introduce duplicate lines, or otherwise do things that + are no longer necessary. + + To confirm these things, you can also review the patched source code in + devtool's workspace, typically in ``<build_dir>/workspace/sources/<recipe>/`` + + Once the review is done, you can create and publish a layer commit with + the patch updates that modify the context. Devtool may also refresh + other things in the patches, those can be discarded. + + + +Configuring and Disabling QA Checks +=================================== + +You can configure the QA checks globally so that specific check failures +either raise a warning or an error message, using the +:term:`WARN_QA` and :term:`ERROR_QA` +variables, respectively. You can also disable checks within a particular +recipe using :term:`INSANE_SKIP`. For information on +how to work with the QA checks, see the +":ref:`insane.bbclass <ref-classes-insane>`" section. + +.. note:: + + Please keep in mind that the QA checks exist in order to detect real + or potential problems in the packaged output. So exercise caution + when disabling these checks. |
