When synchronizing a folder on a samba share, creating files that begin
with ._ is often forbidden. This prevented the client from creating
its ._sync_abcdef.db file.
Now, it'll check whether the preferred filename is creatable, and if
it isn't it'll use .sync_abcdef.db instead.
The disadvantage is that this alternative path won't be ignored by
older clients - that was the reason for the ._ prefix.
* For conflicts where mtime and size are identical:
a) If there's no remote checksum, skip (unchanged)
b) If there's a remote checksum that's a useful hash, create a
PropagateDownload job and compute the local hash. If the hashes
are identical, don't download the file and just update metadata.
* Avoid exposing the existence of checksumTypeId beyond the database
layer. This makes handling checksums easier in general because they
can usually be treated as a single blob.
This change was prompted by the difficulty of producing file_stat_t
entries uniformly from PROPFINDs and the database.
These would otherwise be line-wrapped by clang-format,
and then consecutive reformattings remove the aligned
comment indentation
Example:
int a; // too long comment
->
int a; // too long
// comment
->
int a; // too long
// comment
Use qCInfo for anything that has general value for support and
development. Use qCWarning for any recoverable error and qCCritical
for anything that could result in data loss or would identify a serious
issue with the code.
Issue #5647
This gives more insight about the logs and allow setting fine-tuned
logging rules. The categories are set to only output Info by default
so this allows us to provide more concise logging while keeping the
ability to extract more information for a specific category when
developping or debugging customer issues.
Issue #5647
We were removing the wholme journal db when the user wanted to keep all files,
But that would also remove the selective sync lists.
We should only remove the metadata table.
Issue #5484
Stale chunks might be there because a file was removed or would just not
be uploaded, for any reason.
We just start the DeleteJob but we don't care if it success or not.

One of the test is testing the case where the file is modified on the server
during the upload. So this test the precondition failed error.
The FakeGetReply logic was modified because resizing a 150MB big QByteArray
by increment of 16k just did not scale when downloading a big file.
The current way of tracking the need to update the metadata without
propagation using a separate flag makes it difficult to track
priorities between the local and remote tree. The logic is also
difficult to logically cover since the possibilities matrix isn't
100% covered, leaving the flag only used in a few situations
(mostly involving folders, but not only).
The reason we need to change this is to be able to track the sync
state of files for overlay icons. The instruction alone can't be
used since CSYNC_INSTRUCTION_SYNC is used for folders even though
they won't be propagated. Removing this logic is however not possible
without using something else than CSYNC_INSTRUCTION_NONE since too
many codepath interpret (rightfully) this as meaning "nothing to do".
This patch adds a new CSYNC_INSTRUCTION_UPDATE_METADATA instruction
to let the update and reconcile steps tell the SyncEngine to update
the metadata of a file without any propagation. Other flags are left
to be interpretted by the implementation as implicitly needing
metadata update or not, as this was already the case for most file
propagation jobs. For example, CSYNC_INSTRUCTION_NEW for directories
now also implicitly update the metadata.
Since it's not impossible for folders to emit CSYNC_INSTRUCTION_SYNC
or CSYNC_INSTRUCTION_CONFLICT, the corresponding code paths in the
sync engine have been removed.
Since the reconcile step can now know if the local tree needs metadata
update while the remote side might want propagation, the
localMetadataUpdate logic in SyncEngine::treewalkFile now simply use
a CSYNC_INSTRUCTION_UPDATE_METADATA for the local side, which is now
implemented as a different database query.
The problem in this case is if we rename the file "xxx" to "invalid\file".
The rename will fail because the new filename constains a slash, and it
will be blacklisted.
But then if the user re-rename the file to "valid_name", then we should
invalidate the blacklist entry and retry to upload. But we did not do
that because renaming don't change the mtime and we did not store the
rename target in the database
IL issue 558
SQLITE_DONE is the indicator for not more query results, which is a legal
thing and not an error condition.
Also, check _getFileRecordQuery for null pointer, as close() wipes it.
The idea is that the next call to any database operation will try to
reopen the database through the checkConnect() method. So even if there
was a disconnect trom the db file, this will reestablish the connection.
In SQLite bindings are not cleared by sqlite3_reset() calls, so
skipping a sqlite3_bind call to create a NULL value doesn't work,
instead the previous value will be written.
To fix this, I clear all bindings in SqlQuery::reset and make sure
to explicitly bind NULL when desired in SqlQuery::bind.
To make sure there's no confusion about SqlQuery::reset and
sqlite3_reset, I rename our method to reset_and_clear_bindings().

* Compute the content checksum (in addition to the optional
transmission checksum) during upload (.eml files only)
* Add hook to compute and compare the checksum in csync_update
* Add content checksum to database, remove transmission checksum
