This comes with a test simulating an open request coming from another
process (although in our case it's really just a thread). The actual
hydration works as expected by cfapi, handling of encrypted files is for
now missing.

For now this implements only the logic necessary to get a test suite
equivalent to the TestSyncVirtualFiles one to pass. It doesn't (yet)
honor request to fetch files from the system.

We will have all the code in public anyway so it can just be compiled
in. Thus no need to go through the plugin loading dance. Replaced the
loading with factory functions. Kept mostly the same structure
otherwise.

If we use those encrypted propagation code paths, we already know from
the discovery phase (and thus the journal db) that the folders are
encrypted so no need to check again.
This will remove another expensive round trip with the server.

This step isn't necessary anymore, no one looks at ClientSideEncryption

Thanks to the new discovery algorithm, we got all the freshest E2EE
information straight from the database so reuse it instead of going
through an in memory copy.

It had a different path convention than all the other jobs, most likely
for legacy reasons because of the tight coupling it had to the settings

No need to look for a token on the outside we can just work properly by
keeping all the state encapsulated in the job.

Now we pull the encrypted metadata during the discovery which is a
better approach than before. This shall remove the need for some of the
deep propfinds we have been using so far. It already simplifies the code
a bit for the download scenario.

This code was actually not breaking most cookie handling by accident.
As the raw cookies where not split properly we added cookies with values like
"key: val; key2 = val2; key3 = val3"
When the code was corrected we overwrote the newer values in the jar with
the old ones from a request.
This was done because the propagator jobs where running in a thread a long
time ago, but this is no longer the case.
(Also QAtomicInt::load is marked as deprecated now)
The original code from csync was stopping at any error.
But we have been whitelisting soeme http error code one by one
to ignore the directory instead of aborting the sync.
However, as there are more requests to continue the sync in case
of error, just ignore most HTTP errors
Issue #7586
On windows we do a test to know if we should change the case of the files,
but that conflict with the test that checks if the file was still there
when the filename is actually the same. Which can happen with virtual files
as they have two representation (the one with and without suffix).
When an item is downloaded because it is restored, it shall be shown in the
sync protocol.
(It is also going to be shown in the not synchronized for a short while, but
that's fine)
Previously the source was deleted (or attempted to be deleted), even if
the new location was not acceptable for upload. This could make data
unavilable on the server.
For #7410
By introducing a PropagateRootDirectory job that explicitly
separates the directory deletion jobs from all the other jobs.
Note that this means that if there are errors in subJobs the
dirDeletionJobs won't get executed.
Previously the job would only become "active" when the downloads
started. That meant that arbitrarily many hash computations could be
queued at the same time.
Since the the file was opened during future creation this could lead to
a "too many open files" problem if there were lots of new-new conflicts.
To change this:
- Make PropagateDownload become active when computing a hash
asynchronously.
- Make the computation future open the file only once it gets run. This
will make it less likely for this problem to occur even if thousands
of these futures are queued.
For #7372
Previously fatal error texts were duplicated: Once they entered the
SyncResult via the SyncFileItem and once via syncError().
syncError is intended for folder-wide sync issues that are not pinned
to particular files. Thus that duplicated path is removed.
For #5088
Previously the pin states of deleted files stayed in the 'flags'
database and could be inadvertently reused when a new file with the same
name appeared. Now they are deleted.
To make this work right, the meaning of the 'path' column in the 'flags'
table was changed: Previously it never had the .owncloud file suffix.
Now it's the same as in metadata.path.
This takes the safe parts from #7274 for inclusion in 2.6. The more
elaborate database schema changes (why use 'path' the join the two
tables in the first place?) shall go into master.
Previously RequestEtagJob did return the etag verbatim (including extra
quotes) while the db had the parsed form. That caused the etag
comparison during discovery move detection to always fail. The test
didn't catch it because the etags there didn't have quotes.
Now:
- RequestEtagJob will parse the etag, leading to a consistent format
- Tests have etags with quotes, detecting the problem
- Close the UploadDevice to close the QFile after the PUT job is done.
This allows winvfs to get an oplock on the file later.
- Don't rely on QFile::fileName() to be valid after
openAndSeekFileSharedRead() was called. The way it is openend on
Windows makes it have an empty filename.
If one adds a new file to an online-only folder the previous behavior
was to upload the file in one sync and dehydrate it in the next. Now
these new files get set to Unspecified pin state, making them retain
their data.
Instead of all at once, to reduce peak memory use.
Changing UploadDevice in this way requires keeping the file open for the
duration of the upload. It also means changes to open(), seek(), close()
to ensure that uses of the device work right when a request needs to
be resent.
Since Qt does not yet transparently resend HTTP2 requests in some cases
we do it manually.
The test showed a problem where the initial non-200 reply would close
the target temporary file and the follow-up request couldn't store any
data. Removing that close() call is safe because there also is a
_saveBodyToFile flag that guards writes to the target file.
The previous patch ensured that the sqlite temporaries weren't deleted
and recreated for every sync run, but there was still time between
client startup and the first sync run where they would have the
"needs-sync" icon.
Previously "no-availability" meant db-error and querying the
availability of a nonexistant path returned AllHydrated.
Now, the availability has a DbError and a NoSuchItem error case.
The db-close operation is likely a leftover from when the SyncEngine
owned its own db connection and serves no purpose anymore.
Closing the db causes the removal of the temporary wal and shm files.
These files are recreated when the db is opened again, which happens
almost immediately.
This is a problem for winvfs because the delete-recreate step wipes the
exclusion state on these files just after the sync is done. That meant
that the db temporaries permanently had a "needs sync" icon marker shown
in the explorer.
Avoiding reopening the db also reduces the number of log messages per
sync.
Previously these result codes during remote discovery of the sync root
would not cause an error and the discovery would get stuck.
Also extends RemoteDiscovery tests to check for errors on the root item.
Previously if one set the instruction to ERROR while forgetting to set
an error status, it'd propagate as FileIgnored. Now the default is
NormalError for INSTRUCTION_ERROR and FileIgnored for
INSTRUCTION_IGNORE.
The idea is that the user's question is "is this folder's data available
offline?" and not "does this folder have AlwaysLocal pin state?".
The the answers to the two questions can differ: an always-local
folder can have subitems that are not always-local and are dehydrated.
The new availability enum intends to describe the answer to the user's
actual question and can be derived from pin states. If pin states aren't
stored in the database the way of calculating availability will depend
on the vfs plugin.
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.
1. The _firstJob is usually deleted by the time the PropagateDirectory
finishes. (deleteLater() is called early)
2. The PropagateDirectory::_item and PropagateRemoteMkdir::_item point
to the same SyncFileItem anyway. This code is a leftover from when
each job had its own instance.
Previously removing the vfs suffix of a file always triggered a
conflict. Now it may just cause a file download.
This was done because users expected symmetry in the rename actions and
renaming foo -> foo.owncloud already triggers the "make the file
virtual" action. Now foo.owncloud -> foo triggers the "download the
contents" action.
Users can rename a file *and* add/remove the vfs suffix at the same time
leading to very complex sync actions. This patch doesn't add support for
them, but adds tests and makes sure these cases do not cause unintened
behavior.
The rename will be propagated, but the users's hydrate/dehydrate request
will be ignored.
This was not required with 2.5 because a size of 0 was ignorted when comparing
size by the csync updater, to be compatible with very old version of the database.
But the we discovery will still think the file is changed if the database contains
a size of 0
It still reads and writes the old format too, but all newly stored
client certs will be in the new form.
For #6776 because Windows limits credential data to 512 bytes in older
versions.
By default, plugins are only searched next to the binary or next to the
other Qt plugins. This optional build variable allows another path to be
configured.
The idea is that on linux the oC packaging probably wants the binary in
something like /opt/owncloud/bin and the plugins in
/opt/owncloud/lib/plugins.
Similarly, distribution packagers probably don't want the plugins next
to the binary or next to the other Qt plugins. This flag allows them to
configure another path that the executable will look in.
As far as I'm aware local discovery can be skipped on folders that are
selective-sync blacklisted, so a local discovery is required when an
entry is removed from the blacklist.
Also rename
avoidReadFromDbOnNextSync() -> schedulePathForRemoteDiscovery()
since the old name might also imply it's not read from db in the local
discovery - which is not the case. Use Folder::
schedulePathForLocalDiscovery() for that.
Creating a new virtual file and replacing a file with a virtual one now
have their own text in the protocol, not just "Downloaded".
To do this, the SyncFileItem type is kept as
ItemTypeVirtualFileDehydration for these actions. Added new code to
ensure the type isn't written to the database.
While looking at this, I've also added documentation on SyncFileItem's
_file, _renameTarget, _originalFile and destination() because some of
the semantics weren't clear.
That change will be useful for the notifications. Previously the
dehydrated files were reported as "newly downloaded", now they're
reported as "updated".
That just complicated things. It's ok if Vfs is not a fully abstract
interface class.
The pinstate-in-db methods are instead provided directly on Vfs and
VfsSuffix and VfsOff use them to implement pin states.
The start() method is simply non-virtual and calls into startImpl() for
the plugin-specific startup code.
The block of code that propagated attributes etc from the previously
existing file was placed *after* the block that renamed the previously
existing file to a conflict name. That meant the propagation didn't work
in the conflict case.
- SyncJournalDB functions now behind internalPinStates() to avoid
accidental usage, when nearly everyone should go through Vfs.
- Rename Vfs::getPinState() to Vfs::pinState()
Any folder with a (potentially deeply) contained error will have
StatusWarning. StatusExcluded marks exclusions. The difference is useful
to know for VFS.
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.
