Inh most case we already have a record from before, so avoid doing a useless
lookup in the database.
In owncloudpropagator.cpp, directories do not have a checksum so no need
to call a function that preserves it
- adjust virtual file path handing
- helpers for vfs suffix adding/removal
- helpers for isDirectory/isVirtual on SyncJournalRecords
- be clear about what PathTuple _local/_server mean
So we can quickly query the items in a parent directory
This uses a custom slite3 function, which means that when downgrading the client,
or using another tool to add entries in the database, any insertion in the metadata
table will produce an error: "unknown function: parent_hash()"
(This will crash the client 2.5)
Since we do not recurse within some directories, many files are not seen.
The stale entry will cleanup by themself as the sync engine try to remove
the files that are already removed.
Should we need to actually do this cleanup, it should be dotected in the
discovery.
Fixes two bugs that appeared since the introduction of the struct:
- when reading permissions from the journal, null ("") was read as
empty-not-null
- when reading permissinos from the server, empty ("") was read as null

Issue #6420
Store the X-Request-ID in the SyncFileItem and also in the blacklist.
Note that for consistency reason, the X-Request-ID is also in the
SyncFileItem if the request succeeds.
Currently there is no UI to access it, but it can be queried with sql
commands
For conflicts generally as well as new files in read-only directories
the context menu will now present delete and move options.

Add an index on the e2eMangledName column in the metadata table

This flagged mostly unused parameters. Didn't enable the
misc-non-private-member-variables-in-classes check as we got a lot of
those. Hopefully we'll get to fix them at some point but that feels too
early and too much work for now.

Otherwise on second sync we wouldn't find anything under a mangled path
and just end up thinking said files were removed.
Signed-off-by: Kevin Ottens <kevin.ottens@nextcloud.com>
Otherwise, after a first sync all the mangled entries would be removed
from the journal. On second sync it would be fine because we'd then have
seen the unmangled names because of the local files. Unfortunately
that'd mean reuploading them for nothing or trying to mkdir again on the
server for nothing... with a chance of using differently mangled names
(although I didn't spot it, I can't exclude it never happened).
This also led to weirdly getting stuck during sync when there was more
than one sync point.

Make the codebase consistent, we already have a lot of implicit pointer comparisons.

We keep NULL in the pure C files in src/csync/std and test/csync.
We also replace Doxygen documentation referring to "NULL" to

Since commit 4dc49ff3, we store an entry in the upload info table even
for non chunked uploads. However, if this fails we don't want to remove
non-existant stale chunks if the upload fails.
Without this commit, we would send a DELETE command to clean non-existant
chunks in the dav/uploads/ namespace.
Before, we only cleared the _avoidReadFromDbOnNextSyncFilter *after* a
sync which meant that we had to sync twice after selective sync setup.
Now, we clear the filter *before* a sync as well which allows the actual
next sync to write the correct etags to the db again - instead of only
the sync after that one.
Also expand on comments and rename _avoidReadFromDbOnNextSyncFilter to
_etagStorageFilter.
Since the release package will be build with unit test, we don't
want to query the env variable at every call to fsCasePreserving.
So only test the env variable at startup.
And the testutility can still change the value.
(The env variable is still used from t8.pl and maybe smashbox)
Issue #6318
Paths can contain the wildcards % and _ and that would lead to odd
behavior.
This patch also clarifies the behavior of avoidReadFromDbOnNextSync()
which previously dependend on whether "foo/bar" or "foo/bar/" was
passed as input.
Possibly affects #6322
(PR #6265)
- Remove the UI completely
- Move the #ifdef inside the FileSystem::moveToTrash function, so it is easier to
implement on other platforms
- Q_OS_UNIX includes mac, so we need to disable it. (not using Q_OS_LINUX because of
other BSD that uses XDG spec as well
- Translate the error messages
- Add a couple of doc comments
QFileInfo::isSymLink() does detect reparse points that are symlinks but
returns false for junctions. The new function FileSystem::isJunction()
can detect those and is used to not recursively delete files inside
directories that are junctions.

discussion in the PR https://codereview.qt-project.org/#/c/113019/.
When populating the tree from the filesystem we need to fill
the e2eMangledName from DB and we when trying to find another
match on the oposite tree we need to take in account that names
don't match and search with the mangled name information
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
If the server has the 'uploadConflictFiles' capability conflict
files will be uploaded instead of ignored.
Uploaded conflict files have the following headers set during upload
OC-Conflict: 1
OC-ConflictBaseFileId: 172489174instanceid
OC-ConflictBaseMtime: 1235789213
OC-ConflictBaseEtag: myetag
when the data is available. Downloads accept the same headers in return
when downloading a conflict file.
In the absence of server support clients will identify conflict files
through the file name pattern and attempt to deduce the base fileid.
Base etag and mtime can't be deduced though.
The upload job for a new conflict file will be triggered directly from
the job that created the conflict file now. No second sync run is
necessary anymore.
This commit does not yet introduce a 'username' like identifier that
automatically gets added to conflict file filenames (to name the files
foo_conflict-Fred-1345.txt instead of just foo_conflict-1345.txt).
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.
This can happen if the upload of a file is finished, but we just got
disconnected right before recieving the reply containing the etag.
So nothing was save din the DB, and we are not sure if the server
recieved the file properly or not. Further local update of the file
will cause a conflict.
In order to fix this, store the checksum of the uploading file in
the uploadinfo table of the local db (even if there is no chunking
involved). And when we have a conflict, check that it is not because
of this situation by checking the entry in the uploadinfo table.

In addition to using the right function when retrieving inodes this
*also* fixes a more general bug ownsql had with storing uint64 values
that didn't fit into an int64.
The assert was made fatal when looking at asserts for #5429#5518
without having a particular problem in mind. Recent reports weakly
suggest that this might lead to occasional crashes for users when
sqlite_close fails in ways that look ignorable.
When users share the same tree several times (say A/ and A/B/ are both
shared) the remote tree can have several entries that have the same
file id. This needs to be respected in rename detection.
Also adds several tests and fixes for issues noticed during testing.
See #6096
We mostly trust the file watchers meaning that we don't re-scan the
local tree if we have done that recently and no file watcher events
have arrived. If the file watchers invalidate a subtree, we rescan
only that subtree.
Since we're not entirely sure the file watchers are reliable, we still
do full local discoveries regularly (1h by default). There is a config
file setting as well as an environment variable to control the interval.
