Bug #45390

Updated by Kefu Chai almost 4 years ago

The problems occurs both in Octopus and Master. 

 This is the simple version of a part of test_compression.cc: 
 <pre><code class="cpp"> 

 #include <errno.h> 
 #include <signal.h> 
 #include <stdio.h> 
 #include <stdlib.h> 
 #include "gtest/gtest.h" 
 #include "common/ceph_context.h" 
 #include "common/config.h" 
 #include "osd/OSDMap.h" 


 TEST(OSDMAP, Dencode) 
 { 
 #include "osdmaps/osdmap.2982809.h" 

   bufferlist orig; 
   orig.append((char*)osdmap_a, sizeof(osdmap_a)); 
   cout << "orig length " << orig.length() 
         << std::endl; 
   orig.hexdump(cout); 
   cout    << std::endl; 
   uint32_t size = 128*1024; 
   OSDMap *o = new OSDMap; 
   o->decode(orig); 
   bufferlist fbl; 
   o->encode(fbl, o->get_encoding_features() | CEPH_FEATURE_RESERVED); 
   cout << "Result: " << ((fbl.contents_equal(orig))?"True":"False") << std::endl; 
   fbl.hexdump(cout); 
   cout    << std::endl; 
   ASSERT_TRUE(fbl.contents_equal(orig)); 
 } 
 </code></pre> 


 

 This fails in the assert test...
