      tests: Resolve Coverity DEADCODE · a893b20e
      John Ferlan 提交于
      Coverity complains that the various checks for autoincrement and changed
      variables are DEADCODE - seems to me to be a false positive - so mark it.

      virsh: Resolve Coverity DEADCODE · b46b7785
      John Ferlan 提交于
      Coverity points out that by using EMPTYSTR(type) we are guarding against
      the possibility that it could be NULL; however, based on how 'type' was
      initialized to NULL, then using nested ternary if-then-else's (?:?:)
      setting either "ipv4", "ipv6", or "" - there is no way it could be NULL.
      Since "-" is supposed to mean something empty in a field - modify the
      nested ternary to an easier to read/process if-then-else leaving the
      initialization to NULL to mean "-" in the formatted output.
      
      Also changed the name from 'type' to 'typestr'.

      Adjust the parentheses in/for the waitpid loops; otherwise, Coverity
      points out:
      
      (1) Event assignment:   Assigning: "waitret" = "waitpid(pid, &status, 0) == -1"
      (2) Event between:      At condition "waitret == -1", the value of "waitret"
                              must be between 0 and 1.
      (3) Event dead_error_condition:     The condition "waitret == -1" cannot
                              be true.
      (4) Event dead_error_begin:     Execution cannot reach this statement:

      virsh: Resolve Coverity DEADCODE · daf27d4d
      John Ferlan 提交于
      Since 0766783a
      
      Coverity complains that the EDIT_FREE definition results in DEADCODE.
      
      As it turns out with the change to use the EDIT_FREE macro the call to
      vir*Free() wouldn't be necessary nor would it happen...
      
      Prior code to above commitid would :
      
        vir*Ptr foo = NULL;
        ...
        foo = vir*GetXMLDesc()
        ...
        vir*Free(foo);
        foo = vir*DefineXML()
        ...
      
      And thus the free was needed.  With the change to use EDIT_FREE the
      same code changed to:
      
        vir*Ptr foo = NULL;
        vir*Ptr foo_edited = NULL;
        ...
        foo = vir*GetXMLDesc()
        ...
        if (foo_edited)
            vir*Free(foo_edited);
        foo_edited = vir*DefineXML()
        ...
      
      However, foo_edited could never be set in the code path - even with
      all the goto's since the only way for it to be set is if vir*DefineXML()
      succeeds in which case the code to allow a retry (and thus all the goto's)
      never leaves foo_edited set
      
      All error paths lead to "cleanup:" which causes both foo and foo_edited
      to call the respective vir*Free() routines if set.

      qemu: Resolve Coverity REVERSE_INULL · 9f845b11
      John Ferlan 提交于
      Coverity complains that checking for !domlist after setting doms = domlist
      and making a deref of doms just above
      
      It seems the call in question was intended to me made in the case that
      'doms' was passed in and not when the virDomainObjListExport() call
      allocated domlist and already called virConnectGetAllDomainStatsCheckACL().
      
      Thus rather than check for !domlist - check that "doms != domlist" in
      order to avoid the Coverity message.

      Handle a few places where Coverity complains about the value being
      unused. For two of them (Close cases) - the comments above the close
      indicate there is no harm to ignore the error - so added an ignore_value.
      For the other condition, added an rc check like other callers.

      Since cd4d5475
      
      Coverity notes that setting 'ret = -3' prior to the unconditional
      setting of 'ret = 0' will cause the value to be UNUSED.
      
      Since the comment indicates that it is expect to allow the code
      to continue, just remove the ret = -3 setting.

      qemu_driver: Resolve Coverity COPY_PASTE_ERROR · f72f0642
      John Ferlan 提交于
      In qemuDomainSetBlkioParameters(), Coverity points out that the calls
      to qemuDomainParseBlkioDeviceStr() are slightly different and points
      out there may be a cut-n-paste error.
      
      In the first call (AFFECT_LIVE), the second parameter is "param->field";
      however, for the second call (AFFECT_CONFIG), the second parameter is
      "params->field".  It seems the "param->field" is correct especially since
      each path as a setting of "param" to "&params[i]".  Furthermore, there
      were a few more instances of using "params[i]" instead of "param->"
      which I cleaned up.

      blockcopy: add a way to parse disk source · 37588b25
      Eric Blake 提交于
      The new blockcopy API wants to reuse only a subset of the disk
      hotplug parser - namely, we only care about the embedded
      virStorageSourcePtr inside a <disk> XML.  Strange as it may
      seem, it was easier to just parse an entire disk definition,
      then throw away everything but the embedded source, than it
      was to disentangle the source parsing code from the rest of
      the overall disk parsing function.  All that I needed was a
      couple of tweaks and a new internal flag that determines
      whether the normally-mandatory target element can be
      gracefully skipped, since everything else was already optional.
      
      * src/conf/domain_conf.h (virDomainDiskSourceParse): New
      prototype.
      * src/conf/domain_conf.c (VIR_DOMAIN_XML_INTERNAL_DISK_SOURCE):
      New flag.
      (virDomainDiskDefParseXML): Honor flag to make target optional.
      (virDomainDiskSourceParse): New function.
