My future work will modify the metadata crawler function to use the storage driver file APIs to access the files instead of accessing them directly so that we will be able to request the metadata for remote files too. To avoid linking the storage driver to every helper file using the utils code, the backing chain traversal function needs to be moved to the storage driver source. Additionally the virt-aa-helper and virstoragetest programs need to be linked with the storage driver as a result of this change.

In "src/util/" there are many enumeration (enum) declarations. Sometimes, it's better using a typedef for variable types, function types and other usages. Other enumeration will be changed to typedef's in the future. Signed-off-by: NJulio Faracco <jcfaracco@gmail.com> Signed-off-by: NEric Blake <eblake@redhat.com>

Each backing store of a given disk is associated with a unique index (which is also formatted in domain XML) for easier addressing of any particular backing store. With this patch, any backing store can be addressed by its disk target and the index. For example, "vdc[4]" addresses the backing store with index equal to 4 of the disk identified by "vdc" target. Such shorthand can be used in any API in place for a backing file path: virsh blockcommit domain vda --base vda[3] --top vda[2] Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

To avoid having the root of a backing chain present twice in the list we need to invert the working of virStorageFileGetMetadataRecurse. Until now the recursive worker created a new backing chain element from the name and other information passed as arguments. This required us to pass the data of the parent in a deconstructed way and the worker created a new entry for the parent. This patch converts this function so that it just fills in metadata about the parent and creates a backing chain element from those. This removes the duplication of the first element. To avoid breaking the test suite, virstoragetest now calls a wrapper that creates the parent structure explicitly and pre-fills it with the test data with same function signature as previously used.

Remove the obsolete field replaced by data in "path". The testsuite requires tweaking as the name of the backing file is now stored one layer deeper in the backing chain linked list.

As for the previous patch, this change is needed to achieve compatibility with all the existing code, where we expect a fully qualified path of local files to be present.
-
由 Peter Krempa 提交于
To allow future change of virStorageFileMetadata to virStorageSource we need to store a full path in the "path" variable as rest of the code expects it to be a full path. Rename the "path" field to "relPath" to keep tracking the info but allowing a real "path" field.

Thanks to the testsuite, I feel quite confident that this rewrite is correct; it gives the same results for all cases except for one. I can make the argument that _that_ case was a pre-existing bug: when looking up relative names, the lookup is supposed to be pegged to the directory that contains the parent qcow2 file. Thus, this resolves the fixme first mentioned in commit 367cd69d (even though I accidentally removed the fixme comment early in 74430fe3). * src/util/virstoragefile.c (virStorageFileChainLookup): Depend on new rather than old fields. * tests/virstoragetest.c (mymain): Adjust test to match fix.

So far, my work has been merely preserving the status quo of backing file analysis. But this patch starts to tread in the territory of making the backing chain code more powerful - we will eventually support network storage containing non-raw formats.

I'm about to add fields to virStorageFileMetadata, which means also adding fields to the testFileData struct in virstoragetest. Alas, adding even one pointer on an x86_64 machine gave me a dreaded compiler error: virstoragetest.c:712:1: error: the frame size of 4208 bytes is larger than 4096 bytes [-Werror=frame-larger-than=] After some experimentation, I realized that each test was creating yet another testChainData (which contains testFileData) on the stack; forcing the reuse of one of these structures instead of creating a fresh one each time drastically reduces the size requirements. While at it, I also got rid of a lot of intermediate structs, with some macro magic that lets me directly build up the destination chains inline. For a bit more insight into what this patch does: The old code uses an intermediate variable as a fixed-size array of structs: testFileData chain[] = { a, b }; data.files = chain; In the new code, the use of VIR_FLATTEN_* allows the TEST_CHAIN() macro to still take a single argument for each chain, but now of the form '(a, b)', where it is turned into the var-args 'a, b' multiple arguments understood by TEST_ONE_CHAIN(). Thus, the new code avoids an intermediate variable, and directly provides the list of pointers to be assigned into array elements: data.files = { &a, &b }; * tests/virstoragetest.c (mymain): Rewrite TEST_ONE_CHAIN to reuse the same struct for each test, and to take the data inline rather than via intermediate variables.

While working on v1.0.5-maint (the branch in use on Fedora 19) with the host at Fedora 20, I got a failure in virstoragetest. I traced it to the fact that we were using qemu-img to create a qcow2 file, but qemu-img changed from creating v2 files by default in F19 to creating v3 files in F20. Rather than leaving it up to qemu-img, it is better to write the test to force testing of BOTH file formats (better code coverage and all). This patch alone does not fix all the failures in v1.0.5-maint; for that, we must decide to either teach the older branch to understand v3 files, or to reject them outright as unsupported. But for upstream, making the test less dependent on changing qemu-img defaults is always a good thing. * tests/virstoragetest.c (testPrepImages): Simplify creation of raw file; check if qemu supports compat and if so use it.

These all existed before virfile.c was created, and for some reason weren't moved. This is mostly straightfoward, although the syntax rule prohibiting write() had to be changed to have an exception for virfile.c instead of virutil.c. This movement pointed out that there is a function called virBuildPath(), and another almost identical function called virFileBuildPath(). They really should be a single function, which I'll take care of as soon as I figure out what the arglist should look like.

The source code base needs to be adapted as well. Some files include virutil.h just for the string related functions (here, the include is substituted to match the new file), some include virutil.h without any need (here, the include is removed), and some require both.
