For example:</p> <p> </p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> - job_id: 56796601 snapshot_time: 1596652184 read_bytes: { samples: 62829, unit: bytes, min: 4096, max:16777216, sum: 141697982464 } write_bytes: { samples: 2146, unit: bytes, min: 955, max: 1154584, sum: 320832894 } getattr: { samples: 0, unit: reqs } setattr: { samples: 0, unit: reqs } punch: { samples: 1, unit: reqs } sync: { samples: 0, unit: reqs } destroy: { samples: 0, unit: reqs } create: { samples: 0, unit: reqs } statfs: { samples: 0, unit: reqs } get_info: { samples: 0, unit: reqs } set_info: { samples: 0, unit: reqs } quotactl: { samples: 0, unit: reqs } </pre> </div></div> <p>The <tt>max</tt> value (max:16777216) has no space between the key and value and is now considered a scalar instead of a key value mapping.</p> LU-13857

jobstats output can produce invalid yaml

Bug Minor Resolved Fixed Feng Lei Joe Grund Wed, 5 Aug 2020 22:03:06 +0000 Fri, 6 May 2022 05:51:27 +0000 Sat, 6 Mar 2021 16:01:03 +0000 Lustre 2.15.0 0 8 <p>Emoly</p> <p>Could you please investigate?</p> <p>Thanks</p> <p>Peter</p> <p>What exactly reports this as a incorrect YAML format? I wonder if this is a issue of the indentation since it generates different type of tokens. </p> <p>According to the spec <tt>max:16777216</tt> is a scalar value and not a key / value pair.</p> <p><a href="https://yaml.org/spec/1.2/spec.html" class="external-link" target="_blank" rel="nofollow noopener">https://yaml.org/spec/1.2/spec.html</a></p> <blockquote><p>Normally, YAML insists the “:” mapping value indicator be separated from the value by white space. A benefit of this restriction is that the “:” character can be used inside plain scalars, as long as it is not followed by white space. This allows for unquoted URLs and timestamps. It is also a potential source for confusion as “a:1” is a plain scalar and not a key: value pair.</p></blockquote> <p>Ah it the lack of spacing. Another thing I noticed is the indentation in job_stats which produces a different sequence of YAML tokens.</p> <p>job_stats:</p> <p>   - job_id:</p> <p>produces </p> <p>STREAM START</p> <p><span class="error">&#91;Block mapping&#93;</span></p> <p> (Key token)</p> <p>scalar job_stats </p> <p>(Value token)</p> <p>&lt;b&gt;Start Block (Sequence)&lt;/b&gt;</p> <p> &lt;b&gt;Start Block (Entry)&lt;/b&gt;</p> <p> <span class="error">&#91;Block mapping&#93;</span></p> <p>(Key token)</p> <p>scalar job_id </p> <p>(Value token)</p> <p>scalar 56744 </p> <p>While -----</p> <p>job_stats:</p> <ul class="alternate" type="square"> <li>job_id: 1231</li> </ul> <p>will drop the block sequence and well as the block end tokens.</p> <p>produces </p> <p>Feng Lei</p> <p>Could you please investigate this issue?</p> <p>Thanks</p> <p>Peter</p> <p><a href="https://review.whamcloud.com/#/c/41709/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/#/c/41709/</a></p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/41709/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/41709/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-13857" title="jobstats output can produce invalid yaml" class="issue-link" data-issue-key="LU-13857"><del>LU-13857</del></a> obdclass: Add white space to output valid YAML.<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 151f5322d30ec52a1b99c852e5adbdbbe6fc7e08</p> <p>Landed for 2.15</p> Related LU-15826 Development Rank 1|i0172v: Rank (Obsolete) 9223372036854775807 Severity
