For duplicate file ids the update phase and reconcile phase determined
the rename mappings independently. If they disagreed (due to different
order of processing), complicated misbehavior would result.
This patch fixes it by letting reconcile try to use the mapping that the
update phase has computed first.
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
Previously we required matching mtimes but that's actually
unnecessary when the question is about whether to skip the
download. We will still update the file's metadata.
Also, adjust behavior when the checksum is weak (Adler32):
in these cases we still depend on equal mtimes.
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
Comparison of file sizes for potential conflicts was added in
0eb9401c62, but did not extend to checking
the file size in case of potential local moves.
This commit adds this check and adds tests for various move+change
scenarios.
On Mac, this halves the time spent in csync_excluded_traversal
when using check_csync_excluded_performance. A similar performance
increase is seen on linux.
Fix performence regression from commit d66c2b5fae
For every new file we would look up every parent directories. Allocating
a new QByteArreay for every parent riectory just to know if it is in the other
tree is wasting lots of CPU.
Use a ByteArrayRef trick, similar to QStringRef
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).
For the remote this was already done long time ago
For windows, this was already partially done
The goal is to avoid needless conversion of the path to local encoding.
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.
Set OWNCLOUD_UPLOAD_CONFLICT_FILES=1 to trigger this behavior.
Note that this is experimental and unsupported. The real feature is
likely to end up in 2.5.
Uploading conflict files is simply done by removing the pattern from
csync_exclude. The rest here deals with making the conflict notification
ui approximately work.
There are still some concerns about where an uploaded conflict file
appears in the sync protocol and issues list (it should be in both, but
is only in one of them currently!).
See #4557.
This always returns true since _csync_statedb_is_empty also always
returns true. This function was initially intended to be a shortcut
in case the database doesn't contain any row, but has been broken since
27fb5d9128 and now won't return false
unless the statement fails.
The _last_db_return_error in _csync_detect_update would take care
of that code path in a more direct and clearer way anyway.
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.
Now that they use the same structure, avoid _csync_detect_update
having to recreate another instance and transfer everything manually.
Any instance created during discovery should now be used all the way
up to SyncEngine::treewalkFile.
This also makes sure that the path and types are properly set in that
object instead of having to pass everything as separate parameters.
This gets rid of csync_ftw_flags_e which was now converted from,
and to csync_ftw_type_e, already in the csync_file_stat_t.
Issue #1817
Otherwise adding patterns that start with # are impossible to add, since
they get treated as comments. Also add this escaping for patterns added
in the ui.
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.
The only difference with csync_s::current is that it's
assigned the value of csync_s::local::type and
csync_s::remote::type, which never change. So might as
well only use the "current" field with constants.
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
Now that csync builds as C++, this will avoid having to implement
functionalities needed by csync mandatorily in csync itself.
This library is built as part of libocsync and symbols exported
through it.
This requires a relicense of Utility as LGPL. All classes moved into
this library from src/libsync will need to be relicensed as well.
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.
