does not shut down at exit (v79) #112
Comments

Thanks for reporting this issue and the included log file! 👍 (Related issues/cause of issue: #10, #11, #13 ) This is a known problem with Qiqqa v79. Most often the culprit is a PDF document in one of your libraries which triggers the issue. The bad news is it's pretty tough to find out which one it is (some times there's even more than one) and besides, that PDF was downloaded/imported for a reason so removing it from the library is not really an option unless the PDF itself is corrupted (can happen during download, while working in the Sniffer, but there are also completely valid PDFs out there which will b0rk v79). The good news is work is being done on a new Qiqqa release which should not exhibit this problem, but there are still a few issues there which I need to resolve involving some of the new features (#82), before this new version is sufficiently usable. When you feel a little adventurous: There's an experimental prerelease (v82pre3) available at https://github.com/GerHobbelt/qiqqa-open-source/releases which should resolve this issue, but that release has a UX issue (#82) which can be circumvented if you know what to do precisely or when BibTeX editing in the Qiqqa Sniffer is not important for your workflow.
IFF you decide to install v82pre3, do note that:

…help speed up closing the application (related to jimmejardine#112). Also add thread-safety around the variables/data which cross thread boundaries.

…ardine#112 ); PDF/OCR threads got locked up via WaitForUIThreadActivityDone() call inside a lock, which would indirectly result in other threads to run into that lock and the main thread locked up in WM message pipe handling triggering a FORCED FLUSH, which, under the hood, would run into that same lock and thus block forever. The lock footprint has been significantly reduced as we can do now that we already have made PDFDocument largely thread-safe ( jimmejardine#101 ). Also moved the Application Shutting Down signalling forward in time: already signal this when the user/run-time zips through the 'Do you really want to exit' dialog, i.e. near the end of the Closing event for the main window. `WaitForUIThreadActivityDone` now does not sit inside a lock any more so everyone is free to call it, while in shutdown state, when the WM message pipe is untrustworthy, we leave the relinquishing to standard lib `Thread.Sleep(50)` to cope with: the small delay should be negligible while we are guaranteed to not run into issues around the exact message pipe state: we also ran into issues invoking some flush/actions via a Dispatcher while the app was clearly shortly into shutdown, so we try to be safe there too. Also patched the StatusManager to not clutter the message pipeline at shutdown by NOT showing any status updates in the UI any more once the user has closed the app window. The status messages will continue to be logged as usual, we only do *not* try to update UI any more. This saves a bundle in cross-thread dispatches in the termination phase of the app when large numbers of pending changes and/or libraries are flushed to disk.

- refactor the application termination handling in various parts of the application.
- Long-running tasks (such as 'gather and save to disk') MUST NOT be done in the UI thread, while that main thread should be kept alive and responsive.
+ Hence cleanup & shutdown actions are relegated to a SafeThreadPool background task, while such cleanup/shutdown actions are flagged as 'not short-circuited at application shutdown time'.
+ Pending tasks (also in SafeThreadPool) are BY DEFAULT marked as short-circuit-able at shutdown time so that not only the PDFOCR job queue but also arbitrary pending background tasks queued in the SafeThreadPool are skipped=short-circuited at shutdown time to reduce the amount of time it takes to quit/exit Qiqqa.
- The maximum 'reasonable wait time for threads to terminate at application shudown' has been set at 15 seconds. That number was *guestimated* as reasonable while testing a rig with 40K+ documents managed by Qiqqa. When this timeout is reached by any monitored background threads, then those threads are forcibly *aborted* as apparently their shutdown detection hasn't been functioning. Keep in mind to keep this timeout relatively high as, for instance, Lucene index saving can take a significant amount of time for large libraries (like the 40K+ one I'm testing with)
- `Utilities.Shutdownable.ShutdownableManager.Instance.IsShuttingDown` is refactored to now be the end-all in answering whether Qiqqa is in the process of shutting down/terminating.
- fixed several memleaks by wrapping IDisposable class instances in `using(){...}` statements: particularly Lucene/search-index based code had several spots where the DevStudio Code Analysis has failed to ever report these, while it did find many others before (when we started working on Qiqqa).
- make Maintainable/MaintainableManager.cs code properly thread-safe by adding appropriate locks around minimal critical sections in order to prevent shutdown activity from being interfered with.

…ormance improvements work: - fixed jimmejardine#121 : this happened due to a slightly over-eager `Dispose()` I introduced previously (:-() which reset the BibTeX content to an empty string, followed up immediately by a still-registered change event handler, which would communicate this 'change' to anyone listening, thus nuking the BibTeX metadata for the given Document. - fixed jimmejardine#82 : part of that work has been done in earlier commits, where the size of of the editor panel (**height**) is designed to stick with the size of the 'fields editor mode' subpanel height so as not to jump up & down while you toggle edit modes. Also done in earlier commits: the RAW editor *wraps* the BibTeX text data so there's no need for a *horizontal* scroller any more; this should make diting in RAW mode a little more palatable, at least it is in my own experience. - Just like commit SHA-1: a540e50, there's more IDisposable work done following the new DevStudio Code Analysis reports while I was hunting memory leaks and hunting down causes of jimmejardine#112 - Tweaked the initial library scan to first search all Qiqqa 'known_web_libraries' config files it can find in the Qiqqa libraries' **base directory**: this should help folks (like me) who wish to recover their old/crashing Qiqqa libraries, which previously would cause Qiqqa v79 and earlier Commercial Versions to crash in all sorts of spectacular ways - mostly due to buggy PDF documents sneaking into the libraries via Sniffer download b0rks and other sources of rottenness (such as the websites themselves). The positive effect of this change should be a stable list of libraries with as many of the original Web Libraries' Names restored as possible. - All libraries are flagged Read/Write instead of marking 'Web Libraries' as ReadOnly, which would block any editing/updating of those libs. As Open Source Qiqqa does not support Commercial Web Libraries in the way they were meant before (as syncable Qiqqa-based Cloud storage), you're working on 'independent copies' anyway, while we have to come up with other means to sync libraries like that. As these buggers can grow huge (mine is 20GB+), free cloud solutions (OneDrive, DropBox, etc.) with their 5GB limits are not a truely viable option. Alas, something to think about. **TODO** - Done another Code Review, scanning for all sorts of spots where the C#/.NET code needs a `using(...){...}` statement or something similar to ensure the allocated memory is actually *released when done*; this conjoins with the IDisposable work done in this commit. - LibrarySyncManager: we now cache the PDF Document Size as we already did with the PDF Document 'File Exists' flag. This should at least reduce the running cost of subsequent invocations of the Sync Details dialog after its first run, when that data is collected. - Performance: for large libraries, the initial load time was extreme, particularly when Qiqqa has 'remembered' that the library was open in its own Library View panel/tab. This is due to two major load factors: the BibTeX record for every document is parsed as part of deriving an AugmentedTitle and AugmentedAuthor set for display. Meanwhile, the library will be initially sorted by *date*, which took an *inordinate* amount of time as every date comparison would access and *(re)parse* the raw text date fields as obtained from the database. Now these parsed dates are cached in the PDFDocument until the cached value(s) are reset by the dates being modified within Qiqqa. - Performance: for large libraries, the Sync Details dialog would take an extreme amount of time, with the UI *locked*. Now we set the busy bee / wait cursor to indicate work is being done, while the work has been offloaded onto a background task. Also, while the PDF Document 'File Exists' state was cached in the PDFDocument record, the *size* of the document was not and thus was (re)calculated every time the user would invoke this dialog, resulting in huge delays as thousands of files' filesize info was (re)fetched from the disk on every invocation of the dialog. This has now been alleviated at least for *subsequent invocations* as the File Size is now also cached next to the File Exists datum in PDFDocument. - Here's the set of Code Analysis reports that were

@monica80: I just put a new prerelease online: v82pre4 at https://github.com/GerHobbelt/qiqqa-open-source/releases/tag/v82.0.7213.27662 You might want to check that one out as it should fix your exiting-Qiiqa problem and has a BibTeX editor in the Qiqqa Sniffer that is usable (contrary to v82pre3, which was rather hairy to use there; see #82). Please let me know how it works out for you. Cheers. |
GerHobbelt
moved this from In progress
to Awaits Feedback / End-User Testing
in TODO list

@GerHobbelt : I installed the v82pre4 (and ran Expedition, as recommended). This has solved my problem of qiqqa not shutting down at exit. Yeah! Qiqqa exits and fully ends. I haven't had a chance to test all aspects of v82pre4 but so far basic functions work. Thanks again! |
|
👍 If there's anything else, don't hesitate to report as an issue here. (BTW: v82pre5 prerelease is available at https://github.com/GerHobbelt/qiqqa-open-source/releases ; not a lot of change, but should be a bit more stable than pre4 and fixes one UI bug where a side panel did not resize) |

Qiqqa20191017-did-not-shut-down.log
When I exit Qiqqa v79, it appears to shut down but it keeps running in the background. I have to use Task Manager to manually End Task. Then I can restart Qiqqa. Attached the last bit of the qiqqa log, in case that's helpful.
Any help will be appreciated. (note: previously posted on the qiqqa help forum)
