Changelog 150-199

version 199

added 'all known files' autocomplete caches, so manage tags dialogs' autocompletes should now always appear quickly
the now caches will be created on startup, which may take a few minutes
deleted the old tag autocomplete cache
wrote a faster initialisation routine for all known files caches
fixed an ac_cache cleanup typo
the client's (usually gigantic) mappings table is temporarily extracted to an external db file, which should have numerous benefits and perhaps a few drawbacks for now
the update will take a few more minutes, and will need lots of disk space, to extract the mappings
the server has a very similar external mappings table, so it will also need a while to update, but future admin backup calls will be a lot quicker, due to a much smaller vacuum
greatly optimised a mass-membership calculation in tag processing
reduced some db check-spam timer that was adding up idle cpu time because of recent ac_cache additions
fixed predicate parent sorting
if swfrender fails to generate a swf thumbnail within 60 seconds, the client will now dump out (rather than hanging indefinitely)
fixed some string-selection dialog layout rules
optimised some 'all known files' search queries
subscriptions will now append new urls in oldest->newest order, roughly preserving that order in the internal url cache
the 8chan thread watcher now accepts .json API urls directly
the repository processing routine will handle server_busy errors more gracefully
cleaned and refactored most media viewer 'canvas' code, dejankifying a whole bunch of related stuff and generally improving the object hierarchy
cleaned up and unified a lot of logic and responsibility for idle checking and shutdown maintenance stop time for some big jobs
misc cleanup
misc dialog cleanup

version 198

ipfs download now parses directory multihashes
ipfs directory trees are thrown up on a new checkbox tree dialog for selection/filtering
created a new download_urls (i.e. multiple urls in one popup) popup call, which the new ipfs directory downloader uses
improved a very inefficient line of sql in the mappings fetch stage of query result building that was also used in the manage tags dialog. on my dev machine, fetching 256 files' mappings dropped from 2.5s to 9ms!
regular gallery pages and 'page of images' pages now have a 'paste input' button to mass-add newline-separated queries from the clipboard
fixed a typo in new txt_tags import folder code
fixed bad autocomplete predicate sorting
fixed some sibling autocomplete search_text matching logic
some byte-based value/range presentation will now correctly convert to bytes, rather than regular decimal numbers
improved linesep splitting code across the program
fixed get/setlabel calls across the program to get/setlabeltext, so ampersand characters are handled properly
wrote an 'all known files' autocomplete cache db and prepped a bunch of code for it--it should be easy to finish next week
added a new regex practise link to the regex dialogs
os x app release should display better on retina displays
misc cleanup

version 197

on client boot, autocomplete caches for specific file/tag service cross-references are now initialised and populated. progress is shown on the splash window
on client boot, surplus autocomplete caches are deleted
on service add, new autocomplete caches are created
on file add/delete, autocomplete caches are updated
on mappings pend/add/rescind pend/delete, autocomplete caches are updated
the new autocomplete caches are consulted for all non-'all known tags' queries
the old autocomplete cache no longer stores counts for specific file services, and the remaining associated maintenance calls are deleted
databases now start their own mainloops
databases now wait for their mainloops to finish prepping any large caches before they return to the controller
the client database waits for autocomplete caches to finish before it finishes its own mainloop
the padding around flash and the animation bar are included more accurately in some media zoom calculations, which should eliminate some general zoom jankiness and accidental 100% flash zoom coincidences that filled up the whole canvas
fixed some clientside server boot error spam when local server or booru had no port set
account refreshes that fail due to a network error will spam less to the log
fixed .txt unicode tag parsing from import folders, which was not decoding at the correct step
administrator immediate repository syncs now sync thumbnail downloads if needed
service thumbnail sync will no longer superfluously check the presence of thumbnails whose files are local
if a tag entered into the manage tags dialog has a sibling that already exists for all files, then a new 'ignore, as the sibling already exists' choice will appear
fixed an overcounting bug in 'selection tags' when importing and adding tags at the same time
fixed a typo in repository sync status text that was overcounting total number of updates by one
fixed youtube downloader, which broke with the new library on my new dev machine
the way that tags and predicates are filtered against a tag autocomplete text entry is now much faster
bumped up the default content update chunk threshold from 100 rows to 5,000, which seems to be speeding up processing significantly, with a cost to recovery latency--see how it works for you

version 196

fixed the 8chan thread watcher for boards that host content on media.8ch.net
improved the thread watcher url check logic so it won't lag with the new fix
cleaned up the ac generation code a little
'all known tags' ac counts are now summed from all the known tag services rather than calculated directly (a <= indicator for when these cases overlap will be forthcoming). this speeds up file add/delete, service reset, a/c fetch time, and general tag processing, and reduces the size of the db
ac generation code now deals with 'is the entry text an exact match or not?' better
ac generation code will now no longer produce non-exact-match siblings on an exact match search
ac generation code will no longer save half complete search text into the db as new tags
on update, the a/c cache and its helper table 'existing tags' will be cleaned of a lot of orphans, which may take a few minutes
fixed some bad unicode path parsing when importing files in some OSes, I think!
fixed some bad read autocomplete sibling substitution
fixed a bug where autocomplete predicate lists would not update if the new list was merely a reorder (which can happen in some unusual sibling cases)
fixed the tumblr parser for the subtly new API
import folders now support loading tags from neighbouring .txt files--check the dialog to set up which tag services you would like to import to
the ipfs file downloader now queries DAG object links, determines if the given multihash is a directory or other complicated object, and if so politely dumps out (handling of directory downloads is forthcoming)
some db code is cleaned up
prepared db code for some future subclasses
wrote most of the new ac cache db
misc cleanup
added some browser addon links to the ipfs help

version 195

wrote up a v1.0 ipfs help page
added ipfs services to 'system:file service'
added a 'multihash prefix' option to ipfs services in 'services->manage services'--it will prefix the given text to multihashes copied to the clipboard (e.g. you could use 'http://127.0.0.1:8080/ipfs/')
fixed a bad repo sync processing bug that was incorrectly assuming packages were completely processed when they often were not
all repos will have their processing timestamps reset on update, forcing a (fast) reprocess of everything they have to cover the previously missed content
fixed 8chan OP image parsing, which was sometimes failing due to absent md5s in the json
widened the splash screen a little more so repo sync text can fit a bit better
a couple of splash status texts are shuffled around
updated to sqlite 3.11.0 for windows
if sqlite3 reports at least version 3.11.0, the db will stick to WAL for large transactions (lke vacuum and content processing), since these are fast now
'namespace:*anything*' will now only appear if the a/c input has no 'subtag' component., e.g. 'character:'
import and export folders now print simple summaries to the log if they do some work
tidied up the 'pages' menu
the various hardcoded 'delete' key events are now also triggered by a backspace on os x
added a rough 'copy known urls' to the regular thumbnail menu. this is prototype, let me know how you would like this information managed and displayed in future
in prep for the new cache layer, the autocomplete dropdowns (and hence search domains of all contexts) no longer support 'all known files' cross referenced with 'all known tags'
misc cleanup

version 194

ipfs pins and unpins can now be queued up like file repository pending and petitioned, through the regular thumbnail right-click menu, which also reports some/all ipfs pinned selection status
this ipfs action queue is similarly summarised and commited at the normal service 'pending' menu
ipfs's 'pinned', 'to pin', and 'to unpin' statuses are displayed on thumbnails with ipfs-specific icons
you can copy the focussed file's ipfs multihash or all the selected files' ipfs multihashes from the thumbnail menu's share->copy->ipfs multihash
added a .txt tag parser to the 'path tagging' import dialog--it will parse the same sort of txt files the export dialog produces
the client's new 'requests' network code is harmonised, generally improved, and now produces hydrus-compatible exceptions
updated help re the local server and boorus now defaulting to off
db can now remember service-specific filenames (e.g. ipfs multihashes)
cleaned up some overly complicated and confused thumbnail menu code
the pending menu now specifies what it is about to do more plainly

version 193

the client's local server and local booru can be turned off from their respective management panels, and from now on, the client will initialise with them this way.
if the local server or the local booru are not running, their copy/share commands won't appear in right-click menus
the welcome dialog is now a simpler popup message
incidence sorted tag lists are now sub-sorted by a-z lexicographic
pasting many tags that have siblings to the manage tags dialog will ask you if you want to always preference the sibling, saving time
added a 'clear deleted file records' button to the local file service on the review services window
idle mode now cannot naturally engage within the first two minutes since client boot
the autocomplete search logic will not count namespace characters in the autocomplete character threshold, so typing 'character:a' will not typically trigger a (very laggy) full search
putting a '*' anywhere in an autocomplete search_text will force a full search, ignoring the a/c character threshold
moved some specific 'give gui time to catch up' pause code to the generalised pause/cancel code that a lot of stuff uses, so big jobs should generally be a bit more polite
split the daemon class into two--one for big jobs that remains polite, and another for small jobs that triggers regardless of what else is going on. this should increase responsivity for a number of scenarios
fixed some bad wal failure detection and hence no-wal file creation on some instances of db cursor reinit (usually after service modification). because of now many superfluous no-wal files, existing no-wal files will be deleted on db update
some external storage location errors are improved
some internal and external storage location init is improved.
if an error is detected in the external storage location manager, it will not attempt to rebalance again until the client is rebooted
improved some upnp error catching
cleaned up some misc shutdown thread-gui interaction error spam
did some prep work on a future rewrite of daemon jobs pipeline
split up some mixed file/data/404 'stuff was missing' exception code

version 192

added a 'check on ok' button to the manage subscriptions dialog's subscription panel
check file integrity now prints missing paths to the log
fixed a typo that was breaking some repo sync download resumes
if an external storage location does not exist on client boot, a popup will say so
resetting a service is now much faster when the service is large
some repo processing stuff is a bit faster
improved some image rendering error handling
some thumbnail errors are recovered from in a better way
improved db update bit rot resilience
improved the vacuum disk space error popup with better explanation of the problem and solution
misc improvements
moved to win 10 dev machine, so several windows libraries are a bit newer
updated to opencv 3.1.0 on windows

version 191

added ipfs service type
added simple ipfs service gui to manage and review services windows
added simple ipfs download and import to pages menu
split confused service data object into a bunch of more flexible and readable subclasses
raw url downloads are now powered by 'requests' rather than my hacked http engine, and work a hell of a lot better. more to follow
raw url downloads now pause and cancel correctly
optimised some a/c cache clearing in mapping update processing
optimised content update object -> db yield logistics
added no-daemons command line switch to disable all daemons
added no-wal command line switch to disable WAL journalling for the db
if the db fails to read a new WAL-journalled db file it has just created, it will delete the file and attempt to recreate the db, never trying WAL again
changed the way the db writes big repo syncs to disk so that the job can be abandoned much more quickly
improved local file not found error to state the directory or exact path that was the problem
fixed some socket-level error reporting (I think timeout was part of this)
the petition approval and denial client-to-server network commit is broken up into smaller steps to reduce server lag and the overall likelihood of timeouts
subscriptions will no longer add files to their 'successful files' button when the file's url seemed new but it actually was previously deleted
subscriptions will now identify themselves with an additional popup message when they encounter critical errors during sync
editing a clientside service will force a reset of the appropriate session cache, so if you change access key, the account changes will be reflected immediately
the import files dialog will no longer spam error popups on uninteresting or empty files--its 'parsing complete' statement is more verbose instead
the 1.5s gap between parsing complete and the buttons being enabled is also removed. this was supposed to be helpful, to give you a moment to check the files were as expected, but in the end it was just annoying
fixed a typo in some thumbnail error catching and regeneration
improved my network code syncing, so linux and os x releases are cleared out of many old files
misc code cleanup

version 190

fixed some hashing recalculation in collections that meant they reported no files in many cases
fixed some hashing recalculation when 'remove files' is called
improved the way the client db stores file information and service->file mappings
idle processing jobs will now explicitly wake up as soon as the client naturally switches from not idle to idle
the minimum allowed value for the 'max cpu %' control in the maintenance and processing options panel is now 5%
the maintenance and processing panel is rewritten and laid out a little clearer
'busy' is now 'system busy' on the status bar
force idle and force unbusy are now merged into a new 'force idle' that sticks until you explicitly turn it off
busy and idle states should now update immidiately after closing the manage options dialog
improved exit code event order to be less rude to the OS
improved exit code emergency event handling
fixed a typo that was not appropriately skipping the 'do you want to run shutdown jobs?' dialog
file storage folder rebalancing will now occur on shutdown maintenance
the client now closes down more reliably if the db fails to boot
the client now closes down more reliably if the gui fails to boot
if a client vacuum fails, it'll now also raise the exact error sqlite gave
fixed ctrl+a on the autocomplete dropdown (I think the Insert/IME support change broke it)
the ways the 'read' tag autocomplete control talks to other gui elements is improved
the tag autocompletes will now refresh their results lists on more internal variable changes
the query page management controller manages fewer redundant variables
updated sqlite for windows
the client and server dbs will attempt to change to TRUNCATE journal mode if WAL causes a read disk i/o error
misc code cleanup

version 189

split the big analyze db calls into individual table/index calls and moved them from update code to the normal maintenance routines
on vacuum, both the client and server dbs will now bump their page size up to 4096 if they are running on windows (server vacuum is triggered by running a backup)
vacuum should be a slightly faster operation for both the client and server
boosted the db cache significantly--we'll see if it makes much difference for things.
the way the selection tags control updates its taglist on increases to its media cache is massively sped up. An update on a 5,000-thumbnail-strong page now typically works in 3ms instead of ~250ms. large import pages should stream new results much more quickly now
sped up some slow hash calculation code that was lagging a variety of large operations
some hash caching responsibility is moved about to make it available for the add_media_results comparison, which now typically works in sub-millisecond time (was about 16ms before)
some sorted media list index recalculation now works faster
some internal media object hashing is now cached, so sorted list index regeneration is a bit faster
some medialist file counting is now superfast
wrote a new pauser object to break big jobs up more conveniently and reduce gui choking
the repo processing db call now uses this pauser
some copy and mirror directory functions now use this pauser
backup and restore code for the client now skips re-copying files if they share the same last modified date and file size
backup code for the server now skips re-copying files if they share the same last modified date and file size
http cannotsendrequest and badstatusline errors will now provoke two reattempts before being raised
socket error 10013 (no access permission, usually due to a firewall) is caught and a nicer error produced
socket error 10054 (remote host reset connection) is caught, and the connection is reattempted twice before being raised
the old giphy API is gone, so I have removed giphy
forced shutdown due to system exit/logoff is handled better
pubsub-related shutdown exceptions are now caught and silenced
an unusual shutdown exception is now caught
fixed a copy subtag menu typo
cleaned some misc hydrus path code
tags that begin with a colon (like ':)' ) will now render correctly in the media canvas background
some misc code cleanup
dropped flvlib since ffmpeg parses flv metadata better anyway

version 188

if you have custom filters set up, they will now be listed in the normal thumbnail right-click menu, which will expand for them
'refresh account' button's event no longer waits for service response on the gui thread
'refresh account' button on review services will now re-enable if the call fails
added 'hide inbox and archive predicates' checkbox to options->default file system predicates. not sure if this is the best place for it!
system:hash can now query md5, sha1, and sha256
existing pages with system:hash will break on update. since this is such a rare predicate, I assume this is not a problem!
improved db hash cross-reference flexibility
any pausable popups will now explicitly change their text to 'paused' when they are paused
upload pending popup now has a title, so it should pause a little more sanely
regenerate thumbnails popup now has a title, so it should pause a little more sanely
cleaned up some job pause status logic
upload pending now works on a stream, so gigantic uploads will cause fewer hitches and overall problems
upload pending code is cleaned and simplified in several ways, with better error handling and progress reporting
synctotagarchive is now split into a thousand tiny separate jobs and runs on a separate non-db thread. it will no longer lock the db the whole time
synctotagarchive popup should be a lot more responsive and will specifically give the gui some time to catch up after every chunk of data processed
synctotagarchive will update pending tags count (and gui stuff will show the pending tags) as it goes
synctotagarchive is now a pausable and cancellable operation!
large repository sync jobs should be a little less laggy on final commit
system:duration now displays its value as a properly formatted milliseconds time delta, rather than just a big int
profiles now flush to the log immediately
some cpu-heavy daemon recheck periods have been extended to reduce potential hangs on slower computers
some repository sync messaging wording and logic is improved (it should report what it is doing more reliably when you are cpu-busy)
reordered instances of 'waiting politely', so download text/gauge updates should occur before the wait does
some misc 'waiting politely' logic is improved
pixiv ugoira is detected and a better error (that will be ignored by the new sub error throttling code, for instance) is produced
'uninteresting mime' errors have nicer import status note text
fixed the 'thumbnail grid background' custom colour option

version 187

file->restart now works for linux
the 'call to' thread pool now has a delayed start, which fixes a shutdown hang in linux (and perhaps the other platforms, in one way or another), when the user hits 'forget it' on the 'already running' boot dialog
removed some console error junk on abandoned client boot
if a requested full-size thumbnail is missing, the client will now attempt to regenerate it
if a requested full-size thumbnail does not render (for instance, during a request to generate a resized thumbnail), the client will now attempt to regenerate it
some thumbnail fetching and generation logic is slightly improved
you can now drag animated media around when the inital drag click begins over the animation canvas
ditched some ultimately unhelpful mouse warping when the cursor was near the edge of the media viewer when a drag began
possibly fixed a strange tags_fts4 mirroring problem that has hit some users for a reason I do not understand
import tag options panels will no longer order their tag services randomly
fixed a bug where import folders would not save changes to their explicit tags
fixed a bug where under some circumstances, the gallery importer was attempting to display previously deleted files on the screen, causing errors.
subscriptions will now pause a few seconds after a file import error, which should solve a problem with client hanging when lots and lots of subscription file errors occur one after another
if subscriptions encounter 5 file import errors, they will pause their sync and try continuing later
pixiv manga error handling is improved
bad mime error handling is improved for all importers
fixed an important bug in the import status cache where error texts were not being stored as unicode, so error texts with non-unicode-compatible characters were causing exceptions when the session was being saved to the db or the import status frame was being loaded
existing sessions' import status caches should automatically convert their 'notes' to unicode on update
removed booru db fetch spam when booru download page has no work to do
fixed a typo in regenerate thumbnails popup message
fixed some bad event handling for the gallery page's file limit control
updated some regex defaults to have better multiplatform support and handle a wider array of valid characters

version 186

Windows release is now 64-bit!
some libraries got updated for windows, to varying minor effects
BeautifulSoup updated to latest version for everything
fixed a warning from newer versions of BeautifulSoup by explicitly using lxml
updated the running_from_source help file to what is currently needed
ffmpeg.exe is also 64-bit
wrote a "reducing program lag" page for the help
added program restart to file menu, doesn't work for linux yet
improved restart code (it was used in restore database, and for some users would not close the parent process down properly)
in the media viewer, page up/down, arrow keys and mouse scroll no longer unhide the mouse
in the media viewer under Windows, dragging no longer unhides the mouse
the implicit delay in the downloader-importers is reduced, so redundant files should always stream in a super fast now
export files dialog will now auto-create missing destination directories
export files dialog will now work off the gui thread (to stop gui hangups on big jobs) and will report its export status through the export button, which will be disabled until the job is finished
changed the new tab/shift+tab shortcuts because they break panel control navigation (I want to make these editable soon):
'fetch autocomplete results now' shortcut is now Ctrl+Space (Raw Control for OS X, not command)
'IME mode toggle' is now Insert
cleaned up how control is handled cross-platform--in general, 'control' is always control for windows and linux, and 'control' is command for os x. this may be incorrect.
json dump errors now report more information about the specific object and its serialisable contents that are causing the problem
clipped sibling/parent reason entry dialog message when lots of pairs are added
fixed a bit of bad logic in sibling/parent dialog->content-update workflow
fixed the thumbnail canvas not refreshing on a canvas shrink caused by expansion of the management panel that doesn't change the thumb column count
fixed emergency boot error reporting for when HydrusData won't load
added some unicode conversion unit tests

version 185

right clicking on a tag/predicate in the 'selection tags' box or the 'search' list of active predicates provides new intelligent menu options to discard/require/permit/exclude the selected tags from the current search. try it out!
this system also works for namespace and wildcard and system predicates
'predicate a' and its inverse '-predicate a' are no longer considered the same!
namespace and wildcard predicates will now remove their inverts if they are added to the list of active predicates
the way inverse predicates are generated and compared is generalised and improved
fixed 'open a new search page for tag x', which might have been broken?
quick-entering a tag in the 'read' tag autocomplete entry will now always replace with a sibling if one exists
quick-entering a tag in the 'write' tag autocomplete entry will now not replace with a sibling--you will get the option of what you want to do
when this happens, the preferred sibling is labelled on the 'what do you want to do?' popup in the manage tags dialog
also when this happens, the affected file count for add/pend the preferred sibling should now be correct
fixed client support for tags that begin with ':', such as many emoticons. these should now be parsed correctly from websites and keyboard input, keep their leading colon through network and db conversions, and display correctly (for the most part!), despite a little bit of magic to make them work
created a new TimeDelta control to handle finer tuning of optional periods
improved timedelta->pretty string code to support >60s times
manage subscriptions dialog now supports day and hour period, with min period of four hours
manage export folders dialog now supports day/hour/minute period, and the parent dialog displays that time delta appropriately
manage import folders dialog now supports day/hour/minute period, and the parent dialog displays that time delta appropriately
the thread watcher now supports hour/minute/seconds check period
folded 'search' and 'download' menus into 'view' and renamed it 'pages'
'sessions' moved from 'file' to the new 'pages'
moved 'admin' menu to 'services->administrate services'
added 'forced system:limit' to options->speed and memory panel
if several system:limits exist in a search, the minimum will be used
added a checkbox to options->downloading to replace the traffic light waiting politely indicator with text
subscriptions with failed files will say 'x urls in cache, y failed' on their dialog panel
at the gui level, media that superfluously receives a 'pend tag' instruction for a tag that is already current will discard the instruction (this improves the accuracy of the pending tag count during and after the manage tag dialog)
and the same thing for 'petition tag' when the tag isn't already current
any accidentally added 'namespace:'-type tags will be deleted on update
fixed a bad merge in the manage tag siblings dialog's autocomplete dropdown lists
the thread watcher can now deal with urls with a #54951495 post anchor at the end
refactored some controller manager code
removed some useless old code
cleaned some misc code
improved some bad old orphan deletion code
deleted some old code
finished off some old media result streaming code
refactored a bunch of search stuff from clientdata to clientsearch
rewrote some subs gui/help text to be a bit clearer, and added a help link to the dialog

version 184

added external client_files storage!
you can add external client_files folders in options->file storage locations, further giving them weight
a new daemon will incrementally rebalance your files (and recover orphaned subfolders!) over your different storage locations
you can also force a full rebalance from the new database->maintenance->rebalance file storage
simplified the maintenance and processing panel
the maintenance and processing panel controls now appropriately support being set to 'none'
the 'run jobs on idle?' question is now explicit on the maintenance and processing panel
deselecting 'run jobs on idle/shutdown' will now disable subordinate controls
hitting tab on the autocomplete control now triggers an immediate 'fetch results' call
added a checkbox to options->speed and memory to completely disable automatic autocomplete results fetching (i.e. if you want to manually control a/c result-fetching only with this new tab shortcut)
the new less-laggy autocomplete results fetch won't trigger if the latest query is shorter than the cached query (i.e. you won't get lag when hitting backspace a bunch of times on autocomplete)
hitting shift+tab on the autocomplete control now disables all other key event capture, letting you enter IME without your up/down/enter presses controlling the dropdown list of results
'waiting politely' time is now indicated with a small 'traffic light'-type circle control on all downloader pages
fixed some occasional 'I'll go sit in the top-left corner of the screen and not fix my position' hover window behaviour in Linux
fixed sibling predicate collapse for the 'read' autocomplete dropdown for database results
refactored how predicates are collapsed and sorted to be a bit more sensible
fixed maintenance of local booru data use even if local booru does not receive any requests
improved some service/content update error handling in repository sync
the system:rating value-entry dialog no longer lists its rating services in random order
'open externally' will no longer show for non-local thumbnails' right-click menus
fixed audio/pdf thumbnail display for local booru, although they will be full size for now
harmonised some hex-prefix folder generation code
improved some file and directory copying code
improved upload pending popup message cleanup
added help_dir to hydrusconstants
miscellaneous refactoring
misc cleanup
extracted server-specific services and server resources from the common import path to the server import path
a bit more misc server refactoring
updated a couple of bits of help

version 183

added swf thumbnail support--it works ok for most swfs!
thumbs for existing swf files will generate on db update for both client and server
the server will also generate thumbnails for video on update, which it seems it was not doing before
rewrote some hash comparisons in thumbnail downloading and thumbnail counting code to be a lot faster and memory efficient
fixed thumbnail count invalidation after service sync
in certain cases, fetching autocomplete tag results from the db will be slightly less laggy
if the autocomplete dropdown has cached or otherwise quickly fetchable results, it will refilter for current input as you type, ignoring the normal character delay (i.e. typing through autocomplete is far less laggy now)
fixed a couple of autocomplete tag-parsing bugs for tags with more than one colon character
fixed some key event selection bugs in the autocomplete taglist when there are no results in the list
if there are no results in the autocomplete taglist, the typically caret-moving key events up/down/home/end will move the caret (rather than being uselessly passed on to the empty taglist)
all profiling now goes through a single location
profiling now also prints extensive information on explicit code callers
fixed db profile mode printing display for the new logger
added new pubsub_profile_mode (AKA log-killer)
all menu popup display and explicit memory cleanup is done through a single location
hover windows will now not show whenever a menu is open
hover windows will now not hide whenever a menu is open (useful when trying to go 'copy tag' off the hover taglist's menu!)
a keyerror bug when force_idle_mode was hit right at program start is fixed
unexpected serverside client disconnections are now caught and further request processing is cancelled
middle clicking on an 'empty' system predicate in the a/c dropdown now will throw up the dialog to enter a value and then pass that filled in system pred onto the new search page
duplicate parents (which can occur with overlapping grandparents) are now collapsed
the upload pending popup message cancels properly after 'server busy' events
whenever the client's services are iterated at the view-level, it will now be in random order, to stop sync bottlenecks choking other services (and anything else like this that might have been occuring)
fixed a bug with double-clicking a tag selection on the the tag censorship taglist
fixed the too-fast frame timings on some videos opencv had a problem parsing
loading many video types will now be just a little faster
remote files will no longer present the right-click menu option to share->copy->file
hitting a shortcut for manage ratings from the media viewer canvas will no longer work if you have no ratings services
the base scripts (client.pyw, server.py and test.py) now have a shebang line to facilitate non-Windows use
laid groundwork for external client_files locations
plenty of misc cleaning and refactoring

version 182

all printing to the log should now be unicode safe
some other, miscellaneous file-write locations should now be unicode safe
cleaned up some now-redundant unicode-bytestring conversion error handling
the animation scanbar will now draw a little darker while the animation is paused
the client now uses the same new log object as the server, so all logged data will be copied to the terminal, and all logged statements will be timestamped
the client and server's boot and exit statements are more harmonised
server backup is more log-verbose
server backup now makes a simple copy to 'server_backup' folder--no more _backup nonsense
all serverside requests will now print a line in the form 'PORT METHOD PATH HTTP_CODE in TIME TOOK' to the log
page up and down now work (again?) for the thumbnail view. adding shift also works for selecting a page at a time
improved some animation painting logic
improved some rating control painting logic
improved splash screen painting logic
improved all other, misc painting logic--many things should flicker less or render just a little quicker
ratings hover window will no longer re-layout (causing flicker) on ratings set
improved some media canvas painting logic to de-jaggify some zooming
in the manage options dialog, tag-related gui options are moved from the gui panel to the new tags panel
added 'apply all parents to all services' option to the tags panel
the delete key now removes active search predicates and tags in the manage tags dialog
fixed webm link parsing for rule34hentai.net
