2018-10-30iotests: Unify log outputs between Python 2 and 3Max Reitz
When dumping an object into the log, there are differences between Python 2 and 3. First, unicode strings are prefixed by 'u' in Python 2 (they are no longer in 3, because unicode strings are the default there). Second, the order of keys in dicts may differ. Third, especially long numbers are longs in Python 2 and thus get an 'L' suffix, which does not happen in Python 3. We can get around all of these differences by dumping objects (lists and dicts) in a language-independent format, namely JSON. The JSON generator even allows emitting dicts with their keys sorted alphabetically. This changes the output of all tests that use these logging functions (dict keys are ordered now, strings in dicts are now enclosed in double quotes instead of single quotes, the 'L' suffix of large integers is dropped, and "true" and "false" are now in lower case). The quote change necessitates a small change to a filter used in test 207.

2018-10-30iotests: Modify imports for Python 3Max Reitz
There are two imports that need to be modified when running the iotests under Python 3: One is StringIO, which no longer exists; instead, the StringIO class comes from the io module, so import it from there (and use the BytesIO class for Python 2). The other is the ConfigParser, which has just been renamed to configparser.

2018-10-30iotests: 'new' module replacement in 169Max Reitz

2018-10-30iotests: Explicitly bequeath FDs in PythonMax Reitz
Python 3.4 introduced the inheritable attribute for FDs. At the same time, it changed the default so that all FDs are not inheritable by default, that only inheritable FDs are inherited to subprocesses, and only if close_fds is explicitly set to False. Adhere to this by setting close_fds to False when working with subprocesses that may want to inherit FDs, and by trying to set_inheritable() on FDs that we do want to bequeath to them.

2018-10-30iotests: Different iterator behavior in Python 3Max Reitz
In Python 3, several functions now return iterators instead of lists. This includes range(), items(), map(), and filter(). This means that if we really want a list, we have to wrap those instances with list(). But then again, the two instances where this is the case for map() and filter(), there are shorter expressions which work without either function. On the other hand, sometimes we do just want an iterator, in which case we have sometimes used xrange() and iteritems() which no longer exist in Python 3. Just change these calls to be range() and items(), works in both Python 2 and 3, and is really what we want in 3 (which is what matters). But because it is so simple to do (and to find and remove once we completely switch to Python 3), make range() be an alias for xrange() in the two affected tests (044 and 163). In one instance, we only wanted the first instance of the result of a filter() call. Instead of using next(filter()) which would work only in Python 3, or list(filter())[0] which would work everywhere but is a bit weird, this instance is changed to use a generator expression with a next() wrapped around, which works both in 2.7 and 3.

2018-10-30iotests: Use Python byte strings where appropriateMax Reitz
Since byte strings are no longer the default in Python 3, we have to explicitly use them where we need to, which is mostly when working with structures. It also means that we need to open a file in binary mode when we want to use structures. On the other hand, we have to accomodate for the fact that some functions (still) work with byte strings but we want to use unicode strings (in Python 3 at least, and it does not matter in Python 2). This includes base64 encoding, but it is most notable when working with the subprocess module: Either we set universal_newlines to True so that the default streams are opened in text mode (hence this parameter is aliased as "text" as of 3.7), or, if that is not possible, we have to decode the output to a normal string.

2018-10-29dirty-bitmaps: clean-up bitmaps loading and migration logicVladimir Sementsov-Ogievskiy
This patch aims to bring the following behavior: 1. We don't load bitmaps, when started in inactive mode. It's the case of incoming migration. In this case we wait for bitmaps migration through migration channel (if 'dirty-bitmaps' capability is enabled) or for invalidation (to load bitmaps from the image). 2. We don't remove persistent bitmaps on inactivation. Instead, we only remove bitmaps after storing. This is the only way to restore bitmaps, if we decided to resume source after [failed] migration with 'dirty-bitmaps' capability enabled (which means, that bitmaps were not stored). 3. We load bitmaps on open and any invalidation, it's ok for all cases: - normal open - migration target invalidation with dirty-bitmaps capability (bitmaps are migrating through migration channel, the are not stored, so they should have IN_USE flag set and will be skipped when loading. However, it would fail if bitmaps are read-only[1]) - migration target invalidation without dirty-bitmaps capability (normal load of the bitmaps, if migrated with shared storage) - source invalidation with dirty-bitmaps capability (skip because IN_USE) - source invalidation without dirty-bitmaps capability (bitmaps were dropped, reload them) [1]: to accurately handle this, migration of read-only bitmaps is explicitly forbidden in this patch. New mechanism for not storing bitmaps when migrate with dirty-bitmaps capability is introduced: migration filed in BdrvDirtyBitmap.

2018-10-29bitmap: Update count after a mergeEric Blake
We need an accurate count of the number of bits set in a bitmap after a merge. In particular, since the merge operation short-circuits a merge from an empty source, if you have bitmaps A, B, and C where B started empty, then merge C into B, and B into A, an inaccurate count meant that A did not get the contents of C. In the worst case, we may falsely regard the bitmap as empty when it has had new writes merged into it.

In prior commits that made merge transactionable, we removed the assertion that merge cannot operate on disabled bitmaps. In addition, we want to make sure that we are prohibiting merges to "locked" bitmaps. Use the new user_locked function to check.

2018-10-29block/dirty-bitmaps: add user_locked status checkerJohn Snow
Instead of both frozen and qmp_locked checks, wrap it into one check. frozen implies the bitmap is split in two (for backup), and shouldn't be modified. qmp_locked implies it's being used by another operation, like being exported over NBD. In both cases it means we shouldn't allow the user to modify it in any meaningful way. Replace any usages where we check both frozen and qmp_locked with the new check.
