This allow the sync engine to query the new metadata and update the
overlay icons.
Note: we also need to invalidate the etags because the server does not
change the etag of parent directories that see their share-types changed.

... even if the file is not changed.
We get an UPDATE_METADATA in that case, so make sure we let the
SyncFileStatusTracker know about it.
That means we need to filter out UPDATE_METADATA in the other listeners
of this signal.
Issue #6098
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.
Add state and signal to catch the following two known problems:
* Linux: inotify user watch pool is exhausted. Folder watcher becomes
unreliable.
* Windows: buffer is too small, some notifications are lost but watching
stays reliable.
This makes it unnecessary for FolderMan to manage the list and removes
the need for some forwarders.
This is done in preparation for follow-up commits that want to add
diagnostics to FolderWatcher that shall be available from within Folder.
Unfortunately checking the base-url for redirects in all cases lead
to incorrect behavior in some SAML/OAuth2 edge cases.
This new iteration checks the base url for redirects only if the
standard CheckServerJob can't reach the server. That way the 2.3
behavior is only changed in cases that would have lead to errors.

Issue #6105
Dynamically find the browser trough topLevelWidgets instead of
forwarding the call to the relevant page as it would require to break
many abstration layers (OwncloudSetupWizard -> OwncloudWizard ->
AbstractCredentialsWizardPage -> OwncloudShibbolethCredsPage)
And considering that we want to phase shibboleth down, I tought is
was not worth adding an interface for this.
The OAuth page don't have this problem because it shows a label and
allow the user to re-open the browser.
For some reason, this was working untill I added a call
to X509_REQ_get_subject_name, then the linking suddenly
stopped working (even tougth I'm using a ton of other
OpenSSL calls)
Force to link against 1.0
This network job does a DELETE http request on a URL. It's the
second class that does basically the same, but this one returns
the http return code, and it's set to do a api call.
If the server supports client syde encryption, display
a menu on right click that should display encrypt and decrypt.
ideally it would show the encrypt if the folder is decrypted, and
decrypt if the folder is encrypted but currently there's no way
for the client to know that.
We did not set a log handler so there were no timestamps.
The --debug didn't have an effect, let's use --logdebug like in GUI version.

The issues tab uses custom ordering where overall and summary sync
issues are displayed first. This ordering is preserved by creating
special sorting logic for the "time" column.
It needed special handling anyway, since sorting by time-string would
have yielded incorrect results.
Previously it could only display synchronization progress or "up to
date". Now it also communicates the same overall state that the icon
shows.
See owncloud/enterprise#2134
Comparison of file sizes for potential conflicts was added in

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

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
To reproduce, log in and click "authorize" on the browser, then close
the browser before the client has replied, (but after redirected to localhost,
i.e. when the client is asking the server for the token)
The problem is that socket can be destroyed so we don't need to answer on a
destroyed socket.
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).
The current implementation would return the same value whether the query failed
or if no row would be found. This is something that is currently checked by csync
and needs to be provided if we want to use SyncJournalDB there.
Adjusted all call sites to also check the return value even though they
could still just rely on rec.isValid(), but makes it more explicit as to what
happens for database errors in those cases, if we ever want to gracefully handle
them.
We need to use concatPath to avoid possible double '/' in the URLs if the
account url() ends with '/'.
This has become even more of a problem since commit
d1b8370a4a which was resolving the url after
a redirect where most server actually add a '/' if the url is a folder
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.
Some slot were protected or private but needed to be public.
Some needed a static_cast (can't use qOverload because it is in Qt 5.7)
This is not only a partial change.
This is motivated by the fact that QMetaObject::noralizeSignature takes 7.35%
CPU of the LargeSyncBench. (Mostly from ABstractNetworkJob::setupConnections and
PropagateUploadFileV1::startNextChunk). It could be fixed by using normalized
signature in the connection statement, but i tought it was a good oportunity
to modernize the code.
This commit only contains calls that were automatically converted with clazy.
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.
* The sharing ui does a propfind anyway: use that to query the new
property as well!
* For the socket api, asynchronously query the server for the right url
when an action that needs it is triggered.
The old, manually generated URL will be used as fallback in case the
server doesn't support the new property or the property can't be
retrieved for some reason.

... or child folders
There is also no real reason to forbid the user from syncing the same
folder to multiple location on its hardrive.
A real use case is when the user uncheck a big directory using "choose
what to sync", but would still like to sync a folder within this disabled
tree. The user can now do this with the "add folder" feature
Since 2.3, we even support syncing the same local folder to multiple
remote folder, so why not allow syncing the same remote folder several
times?
Relates to issue #3645
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.
This remove the remaining "other" fields of the sync log to save a
bit of memory.
other_etag and other_fileId don't give much information to the users
and other_instruction will always be INST_NONE anyway.
other_modtime and other_size are kept since they are sometimes used.
They were renamed to have a bit more meaningful name.
SyncEngine::checkPermissions will now fetch its information from the
csync trees since they are now preserved until right after this point.
Fixes#3213
Now that csync is using a more convenient data structure for
its file trees, wait a little bit longer before destroying them and
fetch the remote permissions from the remote tree there instead.
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
Some filesystems, vms or other limitations make using the WAL journal
mode impossible. We are notified of this problem through an sqlite
IOERR for SHMMAP. In that case We want to attempt to fall back to the
DELETE journal mode.
The query args of POST requests become the request body. If there's a
redirect, the redirected url will therefore not contain the query
arguments. Use an explicit request body to make the redirection work.
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.
Also add logging of extended error codes for this IO error, maybe we can
become more specific about which situations should trigger a journal
mode switch.
This is the first time the account url may update outside of
account setup.
Summary of redirection handling:
1. During account setup (wizard)
- status.php gets permanently redirected -> adjust url
- authed PROPFIND gets *any* redirection -> adjust url
2. During connectivity ping (ConnectionValidator)
- status.php gets permanently redirected -> adjust url (new!)
All other redirections should be followed transparently and
don't update the account url in the settings.
When created from scratch, the owncloud icon won't be picked-up by

Issue #2446
When the GET request from askFromUser is scheduled on the QNAM inside
the slot that handles the QNetworkReply::finished signal, it seems to
not get processed at all.
This workaround moves the sending of the new GET to the event loop,
sidestepping the problem.
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 this will make the transition easier.

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.

The mac style has the concept of Layout Item Rectangle that bleeds
widgets margins into parent margins. This unfortunately doesn't work
when the parent layout doesn't have any margin, like we do when we
have the hierarchy:
Vertical(normal margin)
/ Horizontal(no margin, uses parent layout spacing)
/Widget
I guess Qt should propagate remaining uneaten margins to grand-parent
layouts and so on to have this work properly, but nobody seems to
have touched that code since Qt 4.4.
So just try to make the problem less worse by making sure that
all checkboxes we want to align are either in the same layout, or
in a loyout of their own.

Allow upgrade path when the server removes support for oauth

We also need to force the account to commit the config to the disk,
otherwise we may not register we are no longer using owncloud and we
risk sending the password as the token to the token refresh API call
Before commit d3b00532b1,
fetchFromKeychain was called everytime we detect that the creds are
invalid (in AccountState::slotInvalidCredentials)
But since that commit, AccountState was calling askFromUser directly,
breaking the refresh of the token.
So I made sure AccountState::slotInvalidCredentials still calls
refreshAccessToken.
Another change that was made was too be sure to clear the cookies
in HttpCredentials::invalidateToken even when we are only clearing the
access_token. That's because the session with a cookie may stay valid
longer than the access_token
We only want to know if they were touched within the last 15 seconds,
so change the data structure to use a QMultiMap, and sort them by
QElapsedTimer. This allows us to iterate over old entries ordered by
time and to stop once we find a recent entry.
This makes the look-up slower but in most cases the folder watcher
will report any change within milliseconds, and we start from the
most recent. What this really makes slower are actual user file
changes while a fast sync is underways which will need to iterate
over the whole map to find out the file isn't there.
This reduces the growth of the memory usage when downloading a large
amount of files.
We need Qt 5.9 for HTTP2 because, even if Qt 5.8 already has support
for it, there is some critical bug in the HTTP2 implementation which

https://codereview.qt-project.org/186066 ]
When using HTTP2, we can use many more parallel network request, this

Issue #5895
Issues:
- #5661 On mac, iconv did not support all of unicode and some
files with emoji in the filename could not be uploaded
- #5719 , #5676 On linux, we will now support non utf-8 locale
Since these errors are blacklisted, it can take up to 24h to retry items
that had a 507 error for a while. This way users can intervene and cause
an upload attempt immediately.
It now produces a summary error message indicating the problem.
Adjust blacklist database table to contain 'errorCategory'. This is
useful for two things:
- Reestablishing summary messages based on blacklisted errors. For
example if we don't retry a 507ed file, we still want to show the
message about space on the server
- Selectively wiping the blacklist: When we have ui for something like
"I deleted some files, please retry all files now!", we want to
delete all blacklist entries of a specific category only.
* A bunch of code was determining sync status by ad-hoc comparing some
progress info fields. It can now just check the status, making it
easier to comprehend.
* There's a clear indication for "a new sync is starting", which helps
wiping the issues tab at the right time.
For now we use them for:
* csync errors: This allows them to appear in the sync issues tab
* insufficient local disk space, as a summary of individual file errors
Insufficient remote space will use them too, as might other issues that
are bigger than a single sync item.

The QNAM may continue to outlive both.
Rename Credentials::getQNAM() to createQNAM() while we're at it - it's

It would have been much nicer to keep the menu assigned to the
QToolButton, but if one switches away from InstantPopup (to adjust the
entries before they're displayed), the button always gets a menu
indicator that can't be removed.
Having to update the plugins to add a submenu in the context menu,
it's more cost-effective to remove support for legacy macOS versions
than implementing and testing this setup.
The Windows shell extension relied on the response of
SHARE_MENU_TITLE to advance its state machine, but in order
to use the new GET_STRINGS instead, we need to know when the
last string was received. Also add BEGIN for consistency.
* SocketAPI has COPL_LOCAL_LINK / EMAIL_LOCAL_LINK commands
* The nautilus and dolphing shell integrations show a submenu from which
one can share as well as access the private link.
* The SocketAPI provides a new GET_STRINGS command to access localized
strings.
* The private link can also be accessed from the user/group sharing
dialog.
* The numeric file id is extracted from the full id to create the
private link url.
Calling forgetSensitiveData() on account deletion leads to a timer for
clearQNAMCache() being queued. Then the Account object is deleted. The
Credentials object stays alive for now because it has a deleteLater
deleter.
If the timer calls into a slot on the Credentials object, the _account
pointer will be invalid at this time.
As a workaround, move the target slot to Account - that way it will not
be called as the account object is already destroyed.
However since Account and Credentials are mutually dependent, it would
be much preferable if their lifetimes were linked, avoiding this
category of bugs.
The current behavior was introduced in
d40c56eda5 and I currently don't
understand why - maybe there's another way of dealing with the problem
that existed then.
* Add a more functional error view #5516
* Allow filtering of ignores and warnings to see only important bits.
* Navigate from the folder view to the error view by clicking on the
error list with the red background.
* Move the error list into its own ui file to allow easier extension.
* Fix issue around tab id handling in ActivitySettings.
* Rename "Action" column to "Issue".
* Change mouse cursor to hand over button and new error list area

category which allows them to appear as errors in the issues list and in
the shell integration icons.
src/gui/main.cpp:112:9: warning: bool literal returned from 'main' [-Wmain]
Used 1 to keep previous behaviour. I supposed the code was meant
to return success (0), but it does not really matter anyway.
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.
- Add category to the all messages (they did not have it was merged right after
the patch to add category everywhere, but this code did not have it.)
- Make sure there is no warnings in the normal flow. (The wizard does a request
without authentication to determine the auth type)
All our crypto code is handled by qt nodaways.

Issue #5783
When the directry that should be removed by selective sync contains changes,
we ignore the whole sub tree instead of only ignoreing new files.
We cannot ignore the whole directory, we need to ignore only the directory
that do not have files to remove
See owncloud/enterprise#1966
If the server and the client's database go out of sync, there could be
persistent 404 errors. This change ensures that the problem corrects
itself eventually by triggering a remote discovery of the file's
parent folders.
It does not address the root cause that might have lead to the
divergence.
Older ownCloud servers like 8.2.0 used to use integer ids.
This broke when switching to QJson because toString() on JSON
values is strict and returns "" for integers.
This should help clearly delimiting them in the log for multi-account setups.
This information is already available elsewhere in the log in any case.
Issue #5672
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
When a new folder becomes selective-sync excluded, we already mark it
and all its parent folders with _invalid_ etags to force rediscovery.
That's not enough however. Later calls to csync_statedb_get_below_path
could still pull data about the excluded files into the remote tree.
That lead to incorrect behavior, such as uploads happening for folders
that had been explicitly excluded from sync.
To fix the problem, statedb_get_below_path is adjusted to not read the
data about excluded folders from the database.
Currently we can't wipe this data from the database outright because we
need it to determine whether the files in the excluded folder can be
wiped away or not.
See owncloud/enterprise#1965
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
Add the log level and category name in the output. Only output the
thread ID and function name for qCDebug statements as they are not
necessary for general use and make the log harder to read.
Also make sure that the message pattern is set when NO_MSG_HANDLER is
used. Using an environment variable should have priority over it anyway.
When we first detect a 503 (probably from a PROPFIND) and enter the
ServiceUnavailable state, we new trigger a status.php query that will
switch the state to MaintenanceMode if necessary.
Before this patch, to deep folder would just be ignored, without any feedback.
This patch makes it so deep folder are properly shown as ignored in the UI.
Also increase the MAX_DEPTH
Issue: #1067
I'm confident this is unnecessary. The original bug in #3283 was
to call ignoreSslErrors() without an argument in the 'accept'
case, which meant ignoring *all* subsequent SSL errors.
With that fixed, explicitly aborting the reply and resetting QNAM
is not needed since not ignoring the error will lead to the SSL
handshake failing.

* Allow creating nameless shares
* Display token as name for nameless shares
(both to be consistent with server)
* Allow changing a share's name by editing it in the table
* Minor adjustments
Starting from oC 10.0.0 having several public link shares with
different attributes for a path will be supported. This adds
functionality to create, edit and delete these public link shares.
The behavior is currently gated by server version, but should be
adapted to use a capability as soon as one is introduced, see
owncloud/core#27622.
The UI reduces to a single-share version when talking to older servers.
Testing scenarios:
* Link sharing is disabled (by capability, not by theme)
* Required passwords
* Required expiry
* Forbidden 'allow upload' for folders
* New and old servers
Newer servers will have the option of hiding version, versionstring, edition
and productname. They will always send the full information in the capabilities.
By default QNetworkReply::errorString() often produces messages like
"Error downloading <url> - server replied: <reason>"
but the "downloading" part invariably confuses people since the
error might very well have been produced by a PUT request.
This commit produces clearer error messages for HTTP errors.
Additionally:
* Remove some unnecessary null checks from slots connected to
network job signals and document that these signals never send
null replies.
* There was a bug where AbstractNetworkJob::_timedout wasn't
set when derived classes overrode slotTimeout. We now ensure
it's always set by disallowing overrides of slotTimeout.
Instead it now calls onTimedOut, which allows custom handling.
* Several subclasses declared errorString, isTimedOut. Move
these to AbstractNetworkJob.
* Unify handling of OC-ErrorString (via the new, general
Job::errorString)
* Add documentation in various places.
Before we would only open the part of the url that the users entered.
Now if the wizardUrlPostfix is used this is should be appended to that

I believe the problem is caused because 'this' was deleted in ConnectionValidator::reportResult
as the signal connectionResult gets emited. The AccountState::slotConnectionValidatorResult
slot does indeed call slotInvalidCredentials which might call {Shibboleth,Http}Credentials::fetchFromKeychain
which might emit fetched directly, which will call AccountState::slotCredentialsFetched
which deletes the _connectionValidator
So use deleteLater when deleting the _connectionValidator, hoping this helps
* make target duration a client option instead of a capability
* simplify algorithm for determining chunk size significantly
* preserve chunk size for the whole propagation, not just per upload
* move options to SyncOptions to avoid depending on ConfigFile
in the propagator
* move chunk-size adjustment to after a chunk finishes, not when
a new chunk starts
Previously the check box was checked if *any* of its sub-permissions
were granted. This can hide the fact that only a limited subset of them
are actually granted.
The new behavior is to display as "partially checked" if only some
of the sub-permissions are available. Clicking the check box itself
still toggles between granting all or none of them.
When there is no errors _syncResult.firstItemError() is NULL, and accessing
it's _file member is an undefined behavior. (Thankfully, createGuiLog did not
use the string when the count was 0, but we are not supposed to create
null references.

The destructor of the PropagateItemJob will access the propagator's

Order of destruction is the reverse of the order of the members in
the class. So put it at the end so it can be destroyed first.

I didn't want to touch this visible translated string in a

For Qt versions before 5, we continue to show the build-time version
of OpenSSL but it's clearly marked as such.
In 8ef11a38c9, we started blacklisting

So make sure we expire if 0 seconds have expired
The backtrace looks like:
File "atomic_base.h", line 396, in QString::~QString
File "qlist.h", line 442, in OCC::FolderStatusModel::slotUpdateDirectories
This is the only QList operation, and it may crash if the list is empty.
It can be empty if the propfind returned empty results.
I'm not sure how this can be possible to have an empty list there since
the server is always supposed to return at least one entry, for the directory
itself. But it can happen if a directory was transformed in a file, or
if there is a bug on the server.
This is a possible fix for #3850, applying custom window flags (http://doc.qt.io/qt-5.8/qt.html#WindowType-enum) on the connection method dialog. These avoid resizing the dialog and displaying a maximize button on OS X and context help button on Windows.
It is possible to create files with filenames that differ
only by case in NTFS, but most operations such as stat and
open only target one of these by default.
When that happens, we want to avoid uploading incorrect data
and give up on the file.
Typically this situation should never occurr during normal use
of Windows. It can happen, however, when a NTFS partition is
mounted in another OS.
So the title of the column is fully visible.
Adjust the default size and the size policy of the label so it behave
correctly as the window get resized
Issue #5600
The crash reporter shows many crashes in OwncloudPropagator::scheduleNextJob.
We don't really know what could be the cause, but it's probably because
the _activeJobList contains dangling pointer.
So this patch makes sure to remove all the jobs from this list as they get
destroyed.
* For requests:
- reuse the original QNetworkRequest, so headers and attributes
are the same as in the original request
- determine the original http method from the reply and the request
attributes
- keep the original request body around such that it can be sent
again in case the request is redirected
* Simplify the interface that is used for creating new requests in
AbstractNetworkJob.

My theory is that the AccountState stored in a property of the job was destroyed.
before the job timed out.
Therefore, the qobject_cast within the qvariant_cast would call the metaObject()
virtual function on a dangling pointer.
Fix it by storing a QPointer instead which will track the deletion.
This leads to crashes since we changed the connection to the parent
jobs not to be queued anymore.
We don't really need to bubble up the finished state through
parents in that case, and it would also mean that we'd recurse
all the way through leaves as we go up to each parent. So just call
abort directly on the OwncloudPropagator and make sure the abortion
call is posted to the event loop.
Avoid using connections to report up the job tree for signals
that we can directly communicate to the OwncloudPropagator.
This slightly reduces the memory usage and avoid passing those calls
through the whole parent chain.
In preparation for the PropagateDirectory refactoring, simplify things
by removing WaitForFinishedInParentDirectory, which is currently
implemented as a one-level check.
This value is important for directory items, but is however never
used since a directory CSYNC_INSTRUCTION_RENAME item will always be in
PropagateDirectory::_firstJob, which will have to pass through its own
PropagateDirectory job's parallelism() before reaching the parent's
_subJobs optimization.
Since PropagateDirectory::parallelism can only return WaitForFinished
or FullParallelism, that value is lost. So this commit doesn't
change the behavior for directories, and allow file renames to be
scheduled in parallel across directories (which isn't a problem).
It could be possible that _firstJob is marked as finished if
aborted before its parent PropagateDirectory was marked as finished,
allowing a posted scheduleNextJob call to schedule the child job
in-between.
- I checked every occurence of a '%2' and make correct use of the
QString::arg overload that takes several argument instead of chaining
them, because the first argument can contains a '%1'
- I tried to look for every label that they either use plain text or richtext
and escape the user provided strings in there.
By default, followRedirects is true for all requests, to transparently
handle redirections. In the wizard, we have special redirect-handling
code though and that was being skipped.
Setting the flag to false allows the wizard to be aware of redirects
and to handle them in the correct way. Tested with the server described
in
https://github.com/owncloud/administration/tree/master/redirectServer
There's a second bug here, where followRedirects always converts
redirected requests to the GET verb. That means redirected PROPFINDs
will never have worked. This change un-breaks them for the wizard only.
There should be no case that previously worked that stops working now.
The test sets OWNCLOUD_MAX_PARALLEL to 1 to disable parallelism.
But since the max amount of parallelism is twice as much, that does not
work.
So change the way we compute the hardMaximumActiveJob: Use the value of
OWNCLOUD_MAX_PARALLEL to maximize this amount and base the maximum amount
of transfer jobs on it instead of the other way.
A result of this change is that, in case of bandwidth limit, we keep the
default of 6 non-transfer jobs in parallel. I believe that's fine since
the short jobs do not really use bandwidth, so we can still keep the same
amount of small jobs.
This reverts commit e1f5a49c21.
Retrying uploads with insufficent storage errors frequently leads to
high server traffic. See #5537 for links and a sketch of a correct
solution.
If we call
setConfiguration(QNetworkConfiguration());
This sets an invalid configuration on the QNAM.
But later, when we really go online because interfaces are discovered,
QNetworkAccessManagerPrivate::_q_onlineStateChanged is called (with isOnline=true).
And this will set the state to disconnected because customNetworkConfiguration is
true, and the networkConfiguration state is disabled.
The workaround we to fix another bug on Windows in which the default network
configuration was not behaving properly.
The issue on linux is hard to reproduce and only happen in some condition,
but it was reproduced on smashbox when they run two owncloudcmd at the same time.
Issues: #4720 , #3600
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
- Put all tests in the bin directory so that DLLs can be loaded
- Add missing exports
- Skip tests that use code depending on zlib
- The "GMT" timezone is named differently, use the int constructor instead
5 tests are still failing, it's not really worth fixing at the moment
since no developper is currently using Windows as its main platform.
It could be possible that _firstJob is marked as finished if
aborted before its parent PropagateDirectory was marked as finished,
allowing a posted scheduleNextJob call to schedule the child job
in-between.
Previously, we'd try migrating from legacy settings if reading
the settings failed with an error. Now, we try again after a
couple of seconds and eventually give up.
We can do that because the only changes that were in master but not in 2.3 were the
translations change and documentation change, and the support for the 'M' permission
which we want in 2.3.
The sync engine rely on the 'M' in premission to ask for confirmation
(As requested in issue #5340)
But we only want to ask the premission for the 'root' of the mounting point and not
for every subfolders within it.
So we change the discovery phase in a way that it does not keep the 'M' for
children within the external storage.
Added two checkboxes in the Account Wizard in the advanced page to change the first options.
Also added a checkbox in the general settings to ask for confirmation for external storages.
Theme options allow to hide the checkboxes in the wizard.
As described in issue #5340
We now delete subjobs as their propagation is complete. This allows us
to also release the item by making sure that nothing else is holding a
reference to it.
Remove the stored SyncFileItemVector from SyncEngine and SyncResult
and instead gather the needed info progressively as each itemCompleted
signal is emitted.
This frees some holes on the heap as propagation goes, allowing many
memory allocations without the need of requesting more virtual memory
from the OS, preventing the memory usage from increasingly growing.
This was to catch duplicate emissions for PropagateDirectory but we
don't emit this signal anymore from there.
This fixes a warning about PropagatorJob not being a registered metatype.
This reverts commit fe42c1a818.
Previously if you paused/unpaused a folder for a disconnected account
they would prepare to sync and thus display the 'Waiting...' text. With
this change, folders that can't possibly sync don't show text like
this.
When account connectivity changes, all unpaused folders will be
scheduled anyway.
The avatar image is fetched from the server async, thus connect a signal
from the account if the avatar changes.
Server feature https://github.com/owncloud/core/pull/26872 is needed.
The avatar pixmap is fetched from the server by the Connectionvalidator,
once it has validated the user name, it queries the avatar pixmap.
If the server does not have the avatar route, an empty pixmap is stored.
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.
Relates to https://github.com/owncloud/core/issues/26981
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.
Relates to https://github.com/owncloud/core/issues/26981
We do not track the success or error of the DeleteJob because it does not
matter. If it fails, it might be because the chunks were already removed.
If not, the chunks will be stale, but the server must anyway do a few
cleanup from time to time because we do not always remove the chunks
The current logic tried to avoid a DB lookup just to fetch whether
the file is shared or not since that info is already in the
SyncFileItem. The implementation would however need to decrease the
sync count for itself (and parents) before emitting the new status,
thus emitting the OK status for parents before that last child that
ended the propagation for that folder.
Change the implementation to achieve what we want: give the
possibility to decSyncCount to use a pre-fetched sharing state while
still doing the emission for all involved files. This ensures that
the leaf file also gets its status emitted before its parents.
Issue #4797
We currently push the SYNC status for all files that will be propagated,
and then the OK status when those files are propagated.
On top of this, we send those statuses to all clients connected, even
if the socket is kept open by an application that only needed to show
a file open dialog. On macOS we're also using an NSConnection which
means that we have to wait for the RPC call to return from the
extension, which makes bulk status changes possibly heavy.
Reduce the time spent needlessly sending status pushes by limiting
them to files requested through that socket since it connected.
To limit the data to store, only remember the parent directory of
files requested, and store those in a bloom filter.
Note that this adds a requirement to shell extensions: they should
make sure that the status cache only contains entries that have been
requested through the socket API. In other words, the status cache
must be empty when each socket client connects to the socket API.
Otherwise the cached icon type will be shown to the user, and the
SocketAPI won't push new status for that file if it didn't receive
a RETRIEVE_FILE_STATUS.
- Use the looked-up method index also for the invocation
- Do the method name concatenation already on QByteArray since we'll
convert anyway
- Use staticMetaObject instead of metaObject()
Shrinks owncloud binary by 24 KB and libowncloudsync by 14 KB.
I don't know if it has influence on memory usage or runtime speed though.
Was worth a try.
Previously this wasn't happening for errors that were not
NormalErrors because they don't end up in the blacklist.
This revises the resetting logic to be independent of the
error blacklist and make use of UploadInfo::errorCount
instead.
412 errors should reset chunked uploads because they might be
indicative of a checksum error.
Additionally, server bugs might require that additional
errors cause an upload reset. To allow that, a new capability
is added that can be used to advise the client about this.
This displayName() seemed to be based on Account::user() which used
to call _credentials->user(). But then we repurposed user() to be
davUser() and this usage wasn't updated to point back to the username
used for the credentials.
Some custom server use persistent cookies with the auth token. So we should
clear all the cookies when disconnecting.
Account::clearCookieJar is only called from the HTTPCredentials. This funciton
is not used for shibboleth.
There is probably no reasons to keep the HTTP cookie anyway.
Issue #5370
The re-enables the UI, uses Qt API for importing and
stores the certificate/key in the system keychain.
People who had set up client certs need to re-setup the account. This is ok
since it was an undocumented feature anyway.
Fixes#5408#5407.
The problem was that cleanup of the credentials page set the
credentials of the account back to dummy, thereby overriding
things like shib usernames.
This should be broken since a932eac832.
Otherwise it might happen that the model is inconsistant and this can
lead to crash in the worst case.
(For example, if there was a "fetching" label, and we hide it because it
was a 404. In this case, we would not call begin/endRemoveRows, so the
view could still call the model with an index of row 0, that used to be
for the label, but now correspond to the first element of _subs. And
because _subs is empty, this could lead to crashes)
This could make sure that the network job gets deleted if the parent job gets
deleted, and would avoid crashes like:

The csync log level was only set up on startup, and for log files.
Fix the issue by making Logger::isNoop rely on being explicitly activated
for the log window instead of relying on the presence of a connected
signal, and move the csync log level logic in Logger.
The compiler seems to use signed enums and we need to reserve an extra
bit for the sign to avoid the 2 value to overflow and being interpreted
as -2 when read, and thus not being correctly compared to the full enum
value.
The rules to select the webdav url are now:
- If the server reports that the new chunking algorithm is working,
always use remote.php/dav/files/<username>
This capability can be overriden with an environment variable
- Otherwise, use the dav path provided by the theme, which defaults to
remote.php/webdav
This means that with the newer server, the branding can no longer override
the webdav URL. If there is still an usecase for the branding to do so, we
need to find another way to override it. But it is now more complicated to
configure as might need include the username and need different endpoint
depending on the operations (chunks or not)
Issue #4007
As the URL might be print on the logs.
Also don't change the scheme from http to owncloud.
This was required before when we were using neon through csync, but now that
we use QNAM for everything we don't need it. The credentials from the account
are used.
We are going to change the webdav path depending on the capabilities.
But the SyncEngine and csync might have been created before the capabilities
are retrieved.
The main raison why we gave the path to the sync engine was to pass it to csync.
But the thing is that csync don't need anymore this url as everything is done by the
discovery classes in libsync that use the network jobs that use the account for the urls.
So csync do not need the remote URI.
shortenFilename in folderstatusmodel.cpp was useless because the string is the
_file of a SyncFileItem which is the relative file name, that name never
starts with owncloud://.
All the csync test creates the folder because csync use to check if the folder
exists. But we don't need to do that anymore
Some listeners detect whether a sync is finished by checking
for isUpdatingEstimates and completedFiles >= totalFiles. But
if a sync didn't transfer any files we never sent signal
with these values. Now we do.
The "S" in the permission is only for the "Shared with me" files.
It is only used to show the shared status in the overlay icons.
But we also wish to show the shared status for files that are shared
"by" the users. We can find that out using the 'share-types' webdav
property. If set, then we are sharing the object.
We fake a 'S' in the permission as for our purpose, they mean the same.
Issue #4788
The ownCloud 9.1 server has a data-fingerprint property that the admin must
change in case of backup restoration. When this change, the client understands
that a backup was restored, and will generate conflict files and re-upload
new files.
The heuristics based system checks that there is at least two files wose mtime
is put back in the past and no files that goes forward. In that case we ask the
user before creating the conflicts.
This commit disable the heuristics for newer server that have the data-fingerpint.
And change the heuristics to two hours because we want to avoid false positive due
to some clock error, and that 2 hours of lost due to backup restoration is probably
not so bad.
We only ask the user in the heuristics based aproach so in practice this mean that
the "backup-detected" dialog will no longer appear with newer server.

Issue #5224
Two problems:
- In the discovery phase, we need to check the selective sync entries of
the source path in case of renames.
- When the rename is done, we need to actually update the black list in the
database.
Some tests (such as FolderManTest) can polute the config file with invalid
accounts.
(That's because most of the code, (even in libsync) always instentiate a ConfigFile)
The crash reporter shows a lot of crashes in sqlite3_clear_bindings
which seems to indicate that _stmt is null. We should guard against
a null value in order to avoid crashing.
This should only happen if the prepare call fails. We don't usually
check the return value of the prepare call, but if _stmt is null, the
exec call should return false, not true. We check the result of the
exec call, so this should then abort the sync with an error, rather
than crashing.
- Use a white icon if the context menu is visible.
- Enable `QIcon::setIsMask` if compiled on Qt >= 5.6 to allow automatic
macOS color handling.
- No changes if the colored icons are used.
One local folder can now be configured as sync target for multiple
accounts as long as their url and user differ.
Also this patch accepts that the sync folder is behind a symlink.
Also this patch fixes a bug that before the user input was taken
canonically which was not working for the symlink handling.
Instead of using the regular selective-sync UI (where it's unclear what
the "Cancel" button would even mean in this context), provide a
different set of buttons that allow the user to quickly synchronize
all pending big folders, none of them, or perform manual changes
as usual.
Tray: Workaround collection
* QDBus workaround for Qt 5.5.0 only, there were reports of the tray
working fine with 5.5.1. #5164
* OWNCLOUD_FORCE_QDBUS_TRAY_WORKAROUND to force the workaround on an off
* OWNCLOUD_TRAY_UPDATE_WHILE_VISIBLE to enable or disable updating of
the menu while it's visible - disable by default due to problems on OSX and Xubuntu.
* Track the visibility of the tray menu with aboutToShow/aboutToHide
only on OSX - the aboutToHide signal doesn't trigger reliably on linux
* Refactor such that setupContextMenu is different from updateContextMenu
* Don't use on-demand updating of the tray menu when the qdbus workaround
is active, instead to occasional (30s) updates of the tray menu.
We ignored csync log, but we also need to silent Qt debug output.
We need to ignore it at the very begining because there might be
qDebug also in account creation.
Issue #5196
Two bugs:
- The change filed are not considered as move, they are re-downloaded
but the old file was not removed from the database. The change in
owncloudpropagator.cpp takes care of removing the old entries.
- Next sync would then remove the file in the server in the old folder
This was not a problem until we start reusing the sync engine, and
that the _renamedFolders map is not cleared. We were before deleting
a non-existing file. But now we delete the actual file.
Also improve the tests to be able to do move on the server.
This include support for file id.
Issue #5192
In case of the root directory, it may happen that the _item
is empty and the _item->_status is NoStatus. But we still need to report
the proper success or error of the whole propagation. We should really
use _hasError for that. However, _hasError is also defined to NoStatus
if there was no error, so in that case we need to set Success.
This fixes the problem in which the data-fingerprint is not saved on the
database because the SyncEngine think that the sync failed. (Issue #5185)

This is not sufficient as it is not working for the Socket API.
Next commit will fix it in another layer.
Also, not ignoring paths that are not inside the folder is wrong
as it might still happen if the name has a different casing
This reverts commit d5a481f132.
(cherry picked from commit 904cd46f75)
Previously, we only checked the hiddenness of the target file and
ignored the hiddenness of the containing folders. This lead to
undesired behavior when people synced their home folders and there
was a folder watcher notification for a non-hidden file in one of
the hidden folders.
I'm not fully sure why, but sometimes notifications for .foo/bar were
already ignored, but notifications for .foo/bar/car were not. This may
be because of how we set up the FolderWatchers on Linux.
The new behavior is to check all path components for hiddenness, up
until the base path (but excluding the base path, so using a hidden
folder as a sync folder will work).
This is important because we compare the paths from the file system watcher if it
starts with this path.
Same in the SocketAPI where we need to use cannonical paths in the REGISTER_PATH command,
as the plugin themself will do this comparison.

(cherry picked from commit 524220d090)
I got into a situation where the model would endlessly request the directory
contents from the server because we did not notice yet that the server
is actually in maintenance mode while we were expanding the tree view when
changing the tab to the account or when just expanding it by clicking.
Before it was in Folder, however, the command line client does not
have the Folder class. To not duplicate code, the function to generate
the sync journal name went to SyncEngine class.
This would happen if the directory would first need to be created
through an mkdir propagation job. This job's itemCompleted signal
would trigger the directory to show as SYNC even though its children
are still propagating.
Fix the issue by tracking the sync count for each file, affecting
its parents. This allows us to get rid of the O(n) vector lookup
for each status query, and properly track the hierachical sync
status of a directory.
This also removes the itemCompleted signal emission from the
PropagateDirectory job. Since we only needed for overlay icons, and
since this job doesn't do any direct propagation, we can remove it
to ensure that we won't call itemCompleted twice for the item attached
to Propagate*Mkdir jobs (since the PropagateDirectory is backed by
the same SyncFileItem, instruction and status).
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.
Add a missing call that we currently only do in slotItemCompleted.
This would normally only affect the first sync and would have
gotten properly update at the end of the sync anyway.
To be able to test the SyncEngine efficiently, a set of server
mocking classes have been implemented on top of QNetworkAccessManager.
The local disk side hasn't been mocked since this would require adding
a large abstraction layer in csync. The SyncEngine is instead pointed
to a different temporary dir in each test and we test by interacting
with files in this directory instead.
The FakeFolder object wraps the SyncEngine with those abstractions
and allow controlling the local files, and the fake remote state
through the FileModifier interface, using a FileInfo tree structure
for the remote-side implementation as well as feeding and comparing
the states on both side in tests.
Tests run fast and require no setup to be run, but each server feature
that we want to test on the client side needs to be implemented in
this fake objects library. For example, the OC-FileId header isn't
set as of this commit, and we can't test the file move logic properly
without implementing it first.
The TestSyncFileStatusTracker tests already contain a few QEXPECT_FAIL
for what I esteem being issues that need to be fixed in order to catch
up on our test coverage without making this patch too huge.
This is a move away from the original policy where jobs
would only follow redirects in special cases.
Two restrictions are in place:
1. We do not allow protocol downgrades (https -> http)
2. We stop redirects after we find them looping (e.g. old = new url, or
indirectly when looping 10 times).
This is closer to RFC conforming behavior, although currently
we will treat 301 replies like they were 302. This is for a separate
commit.
Error handling (and display) also needs improvement.
Addresses #2791
Once upon a time, the SyncEngine was instantiated once per sync. But now that
the SyncEngine is kept between sync, we need to reset all these variable between
syncs.

Could be the cause of #5092 and the cost is higher than the benefit if this is the case.
A network request taking more than 30 seconds isn't something unlikely in this world

Issue: owncloud/enterprise#1418
This was removed in 0194ebb222
because it breaks on Linux. However, it looks like it is correct
for Windows. In the meantime the surrounding ifdef has changed
from !Q_OS_MAC to Q_OS_WIN, so reverting it makes sense.
Since the SyncEngine now quits and waits for the discovery thread,
the main thread can enter a deadlock where the discovery thread waits
for its directory result.
Add a 2 seconds timer to the discovery thread wait condition
to limit the deadlock time.
This disables the workaround 487e1fdca5ee04fc98c1ed77898df70d740967c8
for servers that are new enough to support fine grained permissions
on federated shares.
The consequence is that the 'reshare' permission is now granted by
default and that users can edit permissions on the usual fine-grained
level again.
The way the client deals with servers <9.1 is unchanged.
Use a QMap to avoid using a full hashtable for only a few entries, and
clear the QMap once we're done with the measuring. This saves a few
hundred bytes per job during propagation that would otherwise only be
freed at the end of the sync.
During propagation, we create a line for each file, taking memory, but
we delete all lines passed 2000 right at the beginning of the next sync.
Since the user has little chances of being able to read past those 2000
lines in the log, we might as well keep it capped at 2000 also during
propagation to prevent it from eating memory.
The SyncRunFileLog owned by the Folder must be destroyed after the
SyncEngine since the SyncEngine will abort during destruction, resulting
in all jobs being aborted.
It's possible that this crash only happens with a debug build.
The FolderWatcher inserts files to be marked as SYNC and we
currently assume that all file statuses will be updated by the
following sync. It's however possible that the FolderWatcher
notify us of a change that csync won't consider necessary to
propagate, in which case a new status wouldn't be pushed and
the file manager would continue showing this file as syncing.
Re-push the file status when emptying the dirty files list
before propagating to avoid this issue, most likely the OK
status.
No need to allocate (and initialize to 0) a 10 MiB buffer for each files, even
when most files are much smaller than that.
So make sure the buffer that we allocate is not bigger than the file size.
And Also 10 MiB is a bit big for a buffer. 500 KiB should be more than enough.
(Too big allocations can cause problem because of memory fragmentation and such)
We first need to set the abort flag to csync and then aborting the discovery
job, otherwise, the discovery thread could start a new job in the mean time.
We also need to make sure that the thread has existed before we destroy the
exclude list.
Events from the crash reporter suggest that the QNAM and its
child replies might get deleted before returning from this method
and the only possible cause we can see is that the inner event
loop has something to do with it.
Try keeping a ref on the QNAM while in this method to make sure
that it won't get deleted by the inner event loop.

FolderDefinition::save and load escapes the alias. We also need to escape

New folder can't be created with alias that needs escaping, but old folder

For issue #4927:
On Windows 10, we get a notification after the sync is finished for file that were
just downloaded. The guard we have against our "own changes" are only working when
the sync is running and the OwncloudPropagator still alive.
Setting the Environment variable only for owncloud makes in inconsistant with
other Qt application running at the same time.

Previously rejecting any kind of certificate meant that the user

* Progress: Skip ignored files #4856
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

This fixes an issue in which too many jobs are started un parallel

chunks are stored in memory.
Probably the fix for #4611
Issue #4855
A typo in the context string made the translation lookup fail.
But also the %Ln was not recognized as a plural form by transifex, so only
the singular was translated
The assert was there to make sure that this case wasn't happening
to eventually be properly tested. Remove the assert for now but this
codepath should eventually be unit tested using this specific situation.
Since the windows implementation first does cache lookups using the
path string, directories need to be passed identically as through
RETRIEVE_FILE_STATUS.
Change the convention to never have a trailing slash for directories
in the protocol. This allows the convention to be applied without
having to access the disk (since we'd need to know if the path is
represented by a directory) and also matches the convention of the
rest of the sync engine. Individual file manager plugins are then
responsible of handling pushed paths as not ending with a trailing
slash.
This also:
- Moves the trailing slash removal logic from the SyncFileStatusTracker
to the SocketApi class
- Remove the unneeded QString::normalized call in fileStatus, since
this should already be done by the FolderWatcher and plugins
Since the statuses are cached and that we can't invalidate the cache,
sending NOP would need to be overwritten by the default OK status
once the client successfully connected. But instead of remembering
which files we NOPed, rather wait until we are ready to sync before
sending the REGISTER_PATH message to the socket API client. It will
also prevent the client from sending unnecessary RETRIEVE_FILE_STATUS
requests.
Also remove AccountState::canSync, since it does the same as
isConnected and syncing is not an account responsibility.
Go through fileStatus like other cases to make sure that all use
cases go through the same code path. This also makes sure to use
lookupProblem which will use lower_bound which is more efficient
for larger sets of sync problems.
This also fixes the issue with lookupProblem that prevented it to
properly match an empty pathToMatch, caused by the fact that the
problem map contains relative paths not starting with a slash.
Make sure that we push the new status when the status of the SyncEngine
changed. SyncEngine::started comes a bit late, only when the propagation
starts, although it's better in this case since child folders will
only switch to Sync in aboutToPropagate.
Also fix an issue with SyncEngine::findSyncItem when using an empty
fileName; this would match and return the wrong item, even though
not currently happening with the code since fileStatus won't call
it with an empty fileName anymore.
As before, we rely on metadata-update SyncFileItem entries for parent
directories to notify us that a directory contains files to propagate,
and to know when all children were propagated through its itemCompleted
signal.
Those metadata SyncFileItems however have a None direction and we need
to add a explicit directory check to show them as Sync.
This fix also handles new files as well as existing ones, so no need
to keep a separate logic for new files.

Issue #4773
When a conflict-rename or a temporary-rename fails, notify the
LockWatcher. It'll regularly check whether the file has become
accesible again. When it has, another sync is triggered.
owncloud/enterprise#1288
If the downloaded file is empty but the PROPFIND previously announced it
should not have been empty, this might mean the file was somehow corrupted
because of a bug on the server and that we should therefore not accept
the file.
Normaly we accept a change between the actual size of the file and what we
got during discovery because the file might have been updated to a new version
inbetween. But after this patch we won't accept the file if it was replaced
by an empty file.
Will help for issue #4583
Also requested by IL for issue 548
This uses the file watcher to keep track of files that were modified
in order to assign them the blue icon.
This is transient state that's not persisted across restarts.
Before commit 1a51b6718a, the wizard was
making sure folder had an alias but this is no longer the case.
So generate still an unique alias.
Alias is not used in the UI any longer, it's just use for internal purposes.
For issue #4737
As discussed on issue ##4460
Having the quote to be queried on subfolder is wrong in the generic case,
so add a branding option to configure it.
This partially reverts commit ff4cdc3161
In the before-propagate slot, new files that wait to be
pushed to the server are remembered in the _syncProblems
map. That way, the parents show a sync icon properly as
asked for in #4682.
After the item has been transfered properly, the item is
removed from the map again because success is the default.
Added in previous commit from pull request #4663
As discussed, we do not need this option so no need to introduce
a new dependency on the config file in the sync engine
If an app modifies the expiration date (for example the password policy
app) then on more recent versions of the server we will get the share
object back REST style. We should use that info!
Fixes#4409
* Add checksums/supportedTypes and checksums/preferredUploadType
capabilities. The default is that no checksum types are supported.
* Remove the transmissionChecksum config option. Servers must now
use the capabilities to indicate that they are fine with the
client sending checksums.
Note: This intentionally breaks brandings that overrode
Theme::transmissionChecksum. The override must be removed and the
server's capabilities must be adjusted to include the new values.
The reason is that updateFolderView is invoked by the
emitted signal folderSyncStateChange() anyway.
This will reduce the traffic over the SocketAPI nicely,
maybe this was the reason why it was slower than before.
There were two issues:
* With the refactoring of how Folder and SyncEngine relate, the
ignore_hidden_files flag on the CSync context was reset after
each sync run and not updated from the configuration again.
* The folder watcher failed to enumerate hidden folders and thus
didn't watch for changes inside them. (linux only)
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 problem with QSet is that the QDateTime was part of
the hash, but that does not make sens as it should be unique
per widget and not per <date, widget>
Instead make it a QHash so there is only one entry per widget.
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.
