* lib/db: Add ExpirePendingFolders().
Use-case is to drop any no-longer-pending folders for a specific
device when parsing its ClusterConfig message where previously offered
folders are not mentioned any more.
The timestamp in ObservedFolder is stored with only second precision,
so round to seconds here as well. This allows calling the function
within the same second of adding or updating entries.
* lib/model: Weed out pending folders when receiving ClusterConfig.
Filter the entries by timestamp, which must be newer than or equal to
the reception time of the ClusterConfig. For just mentioned ones,
this assumption will hold as AddOrUpdatePendingFolder() updates the
timestamp.
* lib/model, gui: Notify when one or more pending folders expired.
Introduce new event type FolderOfferCancelled and use it to trigger a
complete refreshCluster() cycle. Listing individual entries would be
much more code and probably just as much work to answer the API
request.
* lib/model: Add comment and rename ExpirePendingFolders().
* lib/events: Rename FolderOfferCancelled to ClusterPendingChanged.
* lib/model: Reuse ClusterPendingChanged event for cleanPending()
Changing the config does not necessarily mean that the
/resut/cluster/pending endpoints need to be refreshed, but only if
something was actually removed. Detect this and indicate it through
the ClusterPendingChanged event, which is already hooked up to requery
respective endpoints within the GUI.
No more need for a separate refreshCluster() in reaction to
ConfigSaved event or calling refreshConfig().
* lib/model: Gofmt.
* lib/db: Warn instead of info log for failed removal.
* gui: Fix pending notifications not loading on GUI start.
* lib/db: Use short device ID in log message.
* lib/db: Return list of expired folder IDs after deleting them.
* lib/model: Refactor Pending...Changed events.
* lib/model: Adjust format of removed pending folders enumeration.
Use an array of objects with device / folder ID properties, matching
the other places where it's used.
* lib/db: Drop invalid entries in RemovePendingFoldersBeforeTime().
* lib/model: Gofmt.
My local gofmt did not complain here, strangely...
* gui: Handle PendingDevicesChanged event.
Even though it currently only holds one device at a time, wrap the
contents in an array under the "added" property name.
* lib/model: Fix null values in PendingFoldersChanged removed member.
* gui: Handle PendingFoldersChanged event.
* lib/model: Simplify construction of expiredPendingList.
* lib/model: Reduce code duplication in cleanPending().
Use goto and a label for the common parts of calling the DB removal
function and building the event data part.
* lib/events, gui: Mark ...Rejected events deprecated.
Extend comments explaining the conditions when the replacement event
types are emitted.
* lib/model: Wrap removed devices in array of objects as well.
* lib/db: Use iter.Value() instead of needless db.Get(iter.Key())
* lib/db: Add comment explaining RemovePendingFoldersBeforeTime().
* lib/model: Rename fields folderID and deviceID in event data.
* lib/db: Only list actually expired IDs as removed.
Skip entries where Delete() failed as well as invalid entries that got
removed automatically.
* lib/model: Gofmt
This splits the ignore getting to two methods, one that loads from disk
(the old one) and one that just returns whatever is already loaded (the
new one). The folder summary service which is just interested in stats
now uses the latter method. This means that it, and API calls that call
it, does not get blocked by folder I/O.
This adds two new configuration options:
// The number of connections at which we stop trying to connect to more
// devices, zero meaning no limit. Does not affect incoming connections.
ConnectionLimitEnough int
// The maximum number of connections which we will allow in total, zero
// meaning no limit. Affects incoming connections and prevents
// attempting outgoing connections.
ConnectionLimitMax int
These can be used to limit the number of concurrent connections in
various ways.
This adds a statistic to track the last connection duration per device.
It isn't used for much in this PR, but it's available for #7223 to use
in deciding how to order device connection attempts (deprioritizing
devices that just dropped our connection the last time).
Add specific errors for the failures, resulting in this rather than just
the generic "invalid filename":
[MRIW7] 08:50:50 INFO: Puller (folder default, item "NUL"): syncing: filename is invalid: name is reserved
[MRIW7] 08:50:50 INFO: Puller (folder default, item "fail."): syncing: filename is invalid: name ends with space or period
[MRIW7] 08:50:50 INFO: Puller (folder default, item "sup:yo"): syncing: filename is invalid: name contains reserved character
[MRIW7] 08:50:50 INFO: default: Failed to sync 3 items
We created a new fileset before stopping the folder during restart. When
we create that fileset it loads the current metadata and sequence
numbers from the database. But the folder may have time to update those
before stopping, leaving the new fileset with bad data.
This would cause wrong accounting (forgotten files) and potentially
sequence reuse causing files not sent to other devices.
This change reuses the fileset on restart, skipping the issue entirely.
It also moves the creation of the fileset back under the lock so there
should be no chance of concurrency issues here.
The FileSet.Drop operation in there needs to potentially update a whole lot of global lists, which can take a while (longer than the deadlock interval apparently)
With this change we emulate a case sensitive filesystem on top of
insensitive filesystems. This means we correctly pick up case-only renames
and throw a case conflict error when there would be multiple files differing
only in case.
This safety check has a small performance hit (about 20% more filesystem
operations when scanning for changes). The new advanced folder option
`caseSensitiveFS` can be used to disable the safety checks, retaining the
previous behavior on systems known to be fully case sensitive.

This changes the error handling in loading ignores slightly:
- There is a new ParseError type that is returned as the error
(somewhere in the chain) when the problem was not an I/O error loading
the file, but some issue with the contents.
- If the file was read successfully but not parsed successfully we still
return the lines read (in addition to nil patterns and a ParseError).
- In the API, if the error IsParseError then we return a successful
HTTP response with the lines and the actual error included in the JSON
object.
- In the GUI, as long as the HTTP call to load the ignores was
successful we can edit the ignores. If there was an error we show this
as a validation error on the dialog.
Also some cleanup on the Javascript side as it for some reason used
jQuery instead of Angular for this editor...
Group the global list of files by version, instead of having one flat list for all devices. This removes lots of duplicate protocol.Vectors.
