some software (at least outlook native software) may fiddle with CfApi
placeholder metadta and set a .msg file to be out of sync state when
opening it
in that case, we will let the sync engine go over it and decide what to
do
it is then possible in that case that we would just put it back in "in
sync" state

Note that Windows may convert a placeholder file to a regular file when
it is replaced by another file, even if the old and new file (inode,
modified time, file size) are identical.
WIN32_FIND_DATA::dwReserved0 is only initialised in case of
FILE_ATTRIBUTE_REPARSE_POINT is set. This field is not a bit set. Check
corrected to only include all cloud reparse points and not other special
reparse points.

The pin state is a per-item attribute that has an effect on _type:
AlwaysLocal dehydrated files will be marked for hydration and OnlineOnly
hydrated files will be marked for dehydration.
Where exactly this effect materializes depends on how the pin states are
stored. If they're stored in the db (suffix) the dbEntry._type is
changed during the discovery.
If the pin state is stored in the filesystem, the localEntry._type must
be adjusted by the plugin's stat callback.
This patch makes pin states behave more consistently between plugins.
Previously with suffix-vfs pin states only had an effect on new remote
files. Now the effect of pinning or unpinning files or directories is as
documented and similar to other plugins.
This will be used in conjunction with vfs plugins that detect whether a
file has a pending hydration/dehydration through independent means and
communicate that to the discovery through local file type.
The problem here is that we were sometimes allocating the error_string with
qstrdup, which need to be released with delete[] and not free().
Simplify the code by using QString instead.

- Controled by an option.
- New remote files start out as ItemTypePlaceholder, are created with a
.owncloud extension.
- When their db entry is set to ItemTypePlaceholderDownload the next
sync run will download them.
- Files that aren't in the placeholder state sync as usual.
- See test cases in testsyncplaceholders.
Missing:
- User ui for triggering placeholder file download
- Maybe: Going back from file to placeholder?
This is in line with other bools of that struct and gets rid
of clang-tidy's modernize-use-default-member-init warning.
(The trivial alternative to get rid of that warning would be
to use default member init for that bool variable, but I think
it is better to have it as a bitfield.)

If the code was not complex enough syncing two tables
already started to give UNIQUE constrains errors on
simple sync operations, this also adds initial support
remote delete of an encrypted file
Previously, there was csync_ftw_type_e and SyncFileItem::Type. Having
two enums lead to a bug where Type::Unknown == Type::File that went
unnoticed for a good while.
This patch keeps only a single enum.
MSVC stores the enum as signed in the bitfield (contrary to the C++ spec)
Which means that once we store a value such as SyncFileItem::DetailError
in a bitfield, we get a negative value back, then of course, further
comparison fails.
This is mainly for linux, whose local is not UTF-8.
For example, in latin1, it is not possible to encode emoji or chinese character.
If there are such character in the filename, Qt would just save the file using
the replacement character ('?'). Then, on the next sync, client would rename
the files using this replacement character.
Avoid this by ignoring the files which cannot be downloaded because the
filename cannot be represented with the user's locale
Relates to issue #5676 and #5719
This gets rid of the csync_statedb sqlite layer and use
the same code and same connection as the rest of the SyncEngine.
Missing functions are added to SyncJournalDb and change a few minor
things (like changing SyncJournalFileRecord::_modtime to be an int64
instead of a QDateTime, like it was in csync).
Create a specific type that parses the permissions so we can store
it in a short rather than in a QByteArray
Note: in RemotePermissions::toString, we make sure the string is not
empty by adding a space, this was already existing before commit
e8f7adc7ca where it was removed by mistake.
Only store the path since they represent the same thing, and do the
phash conversion during DB lookup like done in libsync.
We could get rid of everything since we also have an index on the path
column, but since it's the primary key this makes the migration non-trivial.
Merge csync_create and csync_init into the constructor and
replace csync_destroy with the destructor.
Also use a QByteArray for csync_s::root_perms and flatten
csync_rename_s as a rename sub-struct of csync_s since it
can now handle C++ types.
Just expose csync_file_stat_t since we don't need an abstraction layer
anymore. Also pass the nodes of both trees directly to the visitor
function.
Issue #1817
Also move csync_normalize_etag to common/utility since we
don't need the char* function anymore.
Remove the single space file_stat->remotePerm codepath since
this won't be used in csync anymore since
8de3bda0b1.
Issue #1817
This is the first commit trying to unify csync_file_stat_s,
csync_vio_file_stat_s and csync_tree_walk_file_s. Use QByteArray
and unique_ptr already since I'm not used to track memory allocations
and this will make the transition easier.
Issue #1817
This will allow us to unify data structures between csync and libsync.
Utility functions like csync_time and c_std are still compiled as C
since we won't need to be coupled with Qt in the short term.
