| 17 | This class adds a step to the package generation process that sanity checks the | ||
| 18 | packages generated by the OpenEmbedded build system. | ||
| 19 | A range of checks are performed that check the build's output | ||
| 20 | for common problems that show up during runtime. | ||
| 21 | Distribution policy usually dictates whether to include this class. | ||
| 22 | </p> | ||
| 23 | <p> | ||
| 24 | You can configure the sanity checks so that specific test failures either raise a warning or | ||
| 25 | an error message. | ||
| 26 | Typically, failures for new tests generate a warning. | ||
| 27 | Subsequent failures for the same test would then generate an error message | ||
| 28 | once the metadata is in a known and good condition. | ||
| 29 | You use the <code class="filename">WARN_QA</code> variable to specify tests for which you | ||
| 30 | want to generate a warning message on failure. | ||
| 31 | You use the <code class="filename">ERROR_QA</code> variable to specify tests for which you | ||
| 32 | want to generate an error message on failure. | ||
| 33 | </p> | ||
| 34 | <p> | ||
| 35 | The following list shows the tests you can list with the <code class="filename">WARN_QA</code> | ||
| 36 | and <code class="filename">ERROR_QA</code> variables: | ||
| 37 | </p> | ||
| 38 | <div class="itemizedlist"><ul class="itemizedlist" type="disc"> | ||
| 39 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">ldflags:</code></em></span> | ||
| 40 | Ensures that the binaries were linked with the | ||
| 41 | <code class="filename">LDFLAGS</code> options provided by the build system. | ||
| 42 | If this test fails, check that the <code class="filename">LDFLAGS</code> variable | ||
| 43 | is being passed to the linker command.</p></li> | ||
| 44 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">useless-rpaths:</code></em></span> | ||
| 45 | Checks for dynamic library load paths (rpaths) in the binaries that | ||
| 46 | by default on a standard system are searched by the linker (e.g. | ||
| 47 | <code class="filename">/lib</code> and <code class="filename">/usr/lib</code>). | ||
| 48 | While these paths will not cause any breakage, they do waste space and | ||
| 49 | are unnecessary.</p></li> | ||
| 50 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">rpaths:</code></em></span> | ||
| 51 | Checks for rpaths in the binaries that contain build system paths such | ||
| 52 | as <code class="filename">TMPDIR</code>. | ||
| 53 | If this test fails, bad <code class="filename">-rpath</code> options are being | ||
| 54 | passed to the linker commands and your binaries have potential security | ||
| 55 | issues.</p></li> | ||
| 56 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">dev-so:</code></em></span> | ||
| 57 | Checks that the <code class="filename">.so</code> symbolic links are in the | ||
| 58 | <code class="filename">-dev</code> package and not in any of the other packages. | ||
| 59 | In general, these symlinks are only useful for development purposes. | ||
| 60 | Thus, the <code class="filename">-dev</code> package is the correct location for | ||
| 61 | them. | ||
| 62 | Some very rare cases do exist for dynamically loaded modules where | ||
| 63 | these symlinks are needed instead in the main package. | ||
| 64 | </p></li> | ||
| 65 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">debug-files:</code></em></span> | ||
| 66 | Checks for <code class="filename">.debug</code> directories in anything but the | ||
| 67 | <code class="filename">-dbg</code> package. | ||
| 68 | The debug files should all be in the <code class="filename">-dbg</code> package. | ||
| 69 | Thus, anything packaged elsewhere is incorrect packaging.</p></li> | ||
| 70 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">arch:</code></em></span> | ||
| 71 | Checks the Executable and Linkable Format (ELF) type, bit size and endianness | ||
| 72 | of any binaries to ensure it matches the target architecture. | ||
| 73 | This test fails if any binaries don't match the type since there would be an | ||
| 74 | incompatibility. | ||
| 75 | Sometimes software, like bootloaders, might need to bypass this check. | ||
| 76 | </p></li> | ||
| 77 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">debug-deps:</code></em></span> | ||
| 78 | Checks that <code class="filename">-dbg</code> packages only depend on other | ||
| 79 | <code class="filename">-dbg</code> packages and not on any other types of packages, | ||
| 80 | which would cause a packaging bug.</p></li> | ||
| 81 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">dev-deps:</code></em></span> | ||
| 82 | Checks that <code class="filename">-dev</code> packages only depend on other | ||
| 83 | <code class="filename">-dev</code> packages and not on any other types of packages, | ||
| 84 | which would be a packaging bug.</p></li> | ||
| 85 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">pkgconfig:</code></em></span> | ||
| 86 | Checks <code class="filename">.pc</code> files for any | ||
| 87 | <code class="filename">TMPDIR/WORKDIR</code> paths. | ||
| 88 | Any <code class="filename">.pc</code> file containing these paths is incorrect | ||
| 89 | since <code class="filename">pkg-config</code> itself adds the correct sysroot prefix | ||
| 90 | when the files are accessed.</p></li> | ||
| 91 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">la:</code></em></span> | ||
| 92 | Checks <code class="filename">.la</code> files for any <code class="filename">TMPDIR</code> | ||
| 93 | paths. | ||
| 94 | Any <code class="filename">.la</code> file continaing these paths is incorrect since | ||
| 95 | <code class="filename">libtool</code> adds the correct sysroot prefix when using the | ||
| 96 | files automatically itself.</p></li> | ||
| 97 | <li class="listitem"><p><span class="emphasis"><em><code class="filename">desktop:</code></em></span> | ||
| 98 | Runs the <code class="filename">desktop-file-validate</code> program against any | ||
| 99 | <code class="filename">.desktop</code> files to validate their contents against | ||
| 100 | the specification for <code class="filename">.desktop</code> files.</p></li> | ||
