Not having these enabled by default is causing significant extra back
and forth with reporters since they must manually use --logdebug for the
log to be useful.
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
The client tracks the files in server and locally, but the
names of the files differ in the server, but we do *not*
wanna rename the files to the server one, we wanna
keep it as is if it's an encrypted file.
Previously we'd use the full regex when the bname triggered a full-path
matching to take place. Now we have a simplified full-traversal regex
for this case that can be significantly faster to apply.
Triggered by #5017 but doesn't actually solve it.
Mainly uses target_include_directories instead of include_directories
so libraries public include directory get automatically added when adding
the target in target_link_library
Unfortunately matching behaved differently on Windows. This patch
restores the previous matching behavior but still uses the new regular
expression based matching.
Further work will hopefully unify the behavior between platforms without
breaking backwards compatibility.
- Clearly mark local and remote discovery start, to make this searchable
even without --logdebug.
- Promote two messages from debug to info: The 'N entries read from db'
message is useful and the 'read from db but ignored' message is rare
and surprising - if there's a bug there we want to see what happened in
the logs.
fopen does not work well with relative path tand forward slashes on windows
This fix the windows textexcludedfiles test.
And also make the code simpler.
Note that the 'trimmed' might be a behavior change, but i think it is ok
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.
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 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.
Issue #5106
csync_exclude.cpp:428:17: error: assigning to 'char *' from incompatible type 'const char *'
bname = path;
^~~~
The C library's strrchr always return 'char*'
Only the C++'s std::strrchr has two overloads
Improves full matches by more than an order of magnitude
and also improves speed of traversal matches by roughly 20%,
judging by the check_csync_exclude performance test.
Make ExcludedFiles something that is instantiated outside of
the CSYNC context and then given to it as a hook.
ExcludedFiles still lives in csync_exclude and the internal
workings haven't been touched.
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
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.
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.
