storage: expose volume meta-type in XML I got annoyed at having to use both 'virsh vol-list $pool --details' AND 'virsh vol-dumpxml $vol $pool' to learn if I had populated the volume correctly. Since two-thirds of the data present in virStorageVolGetInfo() already appears in virStorageVolGetXMLDesc(), this just adds the remaining piece of information, as: <volume type='...'> ... </volume> * docs/formatstorage.html.in: Document new <volume type=...>. * docs/schemas/storagevol.rng (vol): Add it to RelaxNG. * src/conf/storage_conf.h (virStorageVolTypeToString): Declare. * src/conf/storage_conf.c (virStorageVolTargetDefFormat): Output the metatype. (virStorageVolDefParseXML): Parse it, for unit tests. * tests/storagevolxml2xmlout/vol-*.xml: Update tests to match.

storage: use valid XML for awkward volume names $ touch /var/lib/libvirt/images/'a<b>c' $ virsh pool-refresh default $ virsh vol-dumpxml 'a<b>c' default \| head -n2 <volume> <name>a<b>c</name> Oops. That's not valid XML. And when we fix the XML generation, it fails RelaxNG validation. I'm also tired of seeing <key>(null)</key> in the example output for volume xml; while we used NULLSTR() to avoid a NULL deref rather than relying on glibc's printf extension behavior, it's even better if we avoid the issue in the first place. But this requires being careful that we don't invalidate any storage backends that were relying on key being unassigned during virStoragVolCreateXML[From]. I would have split this into two patches (one for escaping, one for avoiding <key>(null)</key>), but since they both end up touching a lot of the same test files, I ended up merging it into one. Note that this patch allows pretty much any volume name that can appear in a directory (excluding . and .. because those are special), but does nothing to change the current (unenforced) RelaxNG claim that pool names will consist only of letters, numbers, _, -, and +. Tightening the C code to match RelaxNG patterns and/or relaxing the grammar to match the C code for pool names is a task for another day (but remember, we DID recently tighten C code for domain names to exclude a leading '.'). * src/conf/storage_conf.c (virStoragePoolSourceFormat) (virStoragePoolDefFormat, virStorageVolTargetDefFormat) (virStorageVolDefFormat): Escape user-controlled strings. (virStorageVolDefParseXML): Parse key, for use in unit tests. * src/storage/storage_driver.c (storageVolCreateXML) (storageVolCreateXMLFrom): Ensure parsed key doesn't confuse volume creation. * docs/schemas/basictypes.rng (volName): Relax definition. * tests/storagepoolxml2xmltest.c (mymain): Test it. * tests/storagevolxml2xmltest.c (mymain): Likewise. * tests/storagepoolxml2xmlin/pool-dir-naming.xml: New file. * tests/storagepoolxml2xmlout/pool-dir-naming.xml: Likewise. * tests/storagevolxml2xmlin/vol-file-naming.xml: Likewise. * tests/storagevolxml2xmlout/vol-file-naming.xml: Likewise. * tests/storagevolxml2xmlout/vol-*.xml: Fix fallout.
