  78                               <h3>cvs_report.pl changes</h3>
  79
  80 <p>The changes to cvs_report.pl involved changing ProcessECRs to look for the start and stop revision numbers in the log. The CVS log has entries like the following:</p>
  81
  82 <div class="code"><pre>
  83 $ cvs log Makefile | grep ^revision
  84 revision 1.9
  85 revision 1.8
  86 revision 1.7
  87 revision 1.6
  88 revision 1.5
  89 revision 1.4
  90 revision 1.3
  91 revision 1.2
  92 revision 1.1
  93 revision 1.1.2.4
  94 revision 1.1.2.3
  95 revision 1.1.2.2
  96 revision 1.1.2.1
  97 revision 1.3.4.1
  98 revision 1.3.2.2
  99 revision 1.3.2.1
 100 </pre></div>
 101
 102 <p>Thus if the from tag is pointing to revision 1.1.2.1 and the to_tag is pointing to revision 1.1.2.4 cvs_report.pl now skips all versions until 1.1.2.4 then picks up ECR numbers from there.</p>

 113   <li>Set a tag for ats (e.g. Lion_common_&lt;<i>mmddyy</i>&gt;).     sually we will tag the ATS as the same date as LynxOS build.</li>
 114   <li>Change directory to your build tree - int_tools area and modify the <tt>__profile.exp</tt> to set the correcty ATS tag that just tagged if it is not the same as lynxos build as defined.</li>

 146
 147                               <p>Either I really just don't understand CVS branching or perhaps we have an error in tagging. I have written a Perl script that will report the ECRs involved between two different CVS tags. When I run this script on the toolchain, comparing tags Lion_com3_2_2_120204 -> Lion_com3_2_2_121604 I see odd results. I believe that the only real ECR involved here is ECR #23084. The following appears in Quintus for that ECR:</p>

 192
 193 <p>So, to me, the ECRs that changed between the CVS tags of Lion_com3_2_2_120204 and Lion_com3_2_2_121604 WRT src/ChangeLog.lynx would be</p>
 194
 195 <ol>
 196   <li>23084</li>
 197   <li>22875</li>
 198   <li>22805</li>
 199 </ol>
 200
 201 <p>(I assume that ECR #22989 was included with the previous toolchain).</p>
 202
 203 <p>Or am I just looking at this the wrong way?</p>
 204
 205 <p>Futhermore, the other files associated with, for example, ECR #22875, are:</p>
 206
 207 <ul>
 208   <li>toolchain.cvsr/src/gdb/gdbtypes.h: 1.2.4.1</li>
 209
 210   <li>toolchain.cvsr/src/ChangeLog.lynx: 1.25.2.30</li>
 211   <li>toolchain.cvsr/src/gdb/gdbtypes.c: 1.2.4.1</li>
 212   <li>toolchain.cvsr/src/gdb/config/i386/tm-i386lynx.h: 1.2.4.3</li>
 213 </ul>
 214
 215 <p>Yet, other than ChangeLog.lynx, all other files have tags that suggest that nothing else changed! For example, gdbtypes.h has Lion_com3_2_2_120204 pointing to revision 1.2 and Lion_com3_2_2_121604 also pointing to 1.2! Likewise for gdbtypes.c and config/i386/tm-i386lynx.h. Is this a tagging error?</p>
