version 248

fixed two more issues with recent update code!
re-applied a more rigorously tested 'invalid subtag' replacement for any user that has experienced incomplete update code in the past few weeks
added some tag rendering options to options->tags that affect most user-facing, non-editing windows:
added custom namespace-subtag connector (i.e. instead of ':')
added 'show namespaces' checkbox (i.e. to keep the colour but lose the namespace, like how most boorus display tags)
created a basic framework for the duplicate filter--it doesn't do anything yet, but you can launch it from the duplicates page to check it out
updated 'reset processing cache' action and added it to review services repository pages
review services now always starts on 'my files'
review services will try to stay looking at the currently selected service through a refresh_services event
fixed some thread-gui refresh interaction in review services
all listctrl-attached delete/remove buttons will now ask if you are sure before they go
reenabled db->maintenance->clear orphans, which it turns out I had already fixed by accident
serverside services will lock themselves more efficiently while generating updates, ensuring 'server busy' responses can always return promptly
fixed tag manage parents a/c entry to remove tags when they already exist in the box (previously, the a/c would only ever add, so a double-click was required to remove)
tuned adminside petition processing so it approves/denies in reasonable-sized chunks
refactored all the taglist gui code to focus on the underlying tag rather than the string representation
plenty of misc taglist cleanup besides
started a unit test suite for listboxes and wrote a thorough test for namespace colour listbox
misc canvas refactoring

version 247

fixed a problem with deleting more than 256 files at once
furthermore, deleting from thumbnail view or after a filter will split delete jobs into chunks of 64 files at a time to reduce gui hang from deleting many tag-heavy files
rewrote canvas media container code to recycle containers, embed windows, animation bars, static image windows, and animation windows. scrolling through all kinds of media is less flickery (less 'grey box' window initialise flicker) and scrolling through static images should be completely flickerless! William Gibson slideshow speed works again!
this flickerless static image transition will be particularly useful in the forthcoming duplicate image filter!
got adminside petition processing working again
petition counts and fetching is now split by content_type and status
the approve/deny colour hint is more obvious on the petition panel
petitions now process off the main gui thread and throw up a popup message
added 'check all' and 'check none' buttons to petition panel
several serverside petition processing fixes
generalised and improved dynamic menu check item initialisation and inversion support
moved the 'get tags even if file already in db' option into a cog button on regular downloader pages
added a default menu option for 'get tags even if file already in db' to the same cog button
added this cog button to the edit subscription panel as well
fixed exporting tags to Hydrus Tag Archives
fixed exporting 'all known tags' to HTAs
cleaned some HTA and related code
fixed namespace based tag censorship
fixed autocomplete not filtering out current/pending counts if they are set to 'excluded'
fixed generation of non-expiring new accounts
fixed some v245->v246 tag improvement code that was replacing invalid tags with the incorrect namespace
patched a problem with '-:' dirty tag in the v245->v246 update code--I'm not sure what it was doing, but it catches the unusual problem and puts it in the 'invalid tags' category, so let me know if you get trouble with this in future
wrote unit tests for bytesdictionary and shortcuts serialisable objects
harmonised and improved how separators are appended to menus
cleaned up some client db index creation
cleaned up some client tuple stripping
misc pylint warnings cleanup
misc fixes

version 246

fixed a critical bug in serverside content deserialisating that meant servers were not processing most client-submitted data properly
fixed a critical bug in 'all known tags' autocomplete regeneration--please run database->regen->a/c cache when it is convenient and let me know if your numbers are still off
fixed the pre-v238 update problem for good by abandoning update attempts and advising users to try v238 first
clientside invalid tags will now be collapsed like with the server last week. if a tag is invalid (typically something with an extra space, like "series: blah"), the update code will attempt to replace existing mappings with the collapsed valid version. some unusual cases may remain--they will be replaced with 'invalid namespace "series "' and similar. Please remove and replace these when convenient and contact me if there are way too many for you to deal with
duplicates pages now have a file domain for the filtering section, and they remember this domain through session loads
this file domain is accurate--counting potential duplicates and fetching pairs for 'show some pairs' only from those domains. the issue of remote files appearing should be gone!
there is now only one 'idle' entry in the duplicates page cog menu--it combines the three previous into one
fixed numerous irregularities across the wildcard code. all search input now has an implicit '*' on the end unless you put a '*' anywhere else, in which case it acts exactly as you enter it, with a non-* beginning matching beginning of string, whitespace, or colon, and non-* end matching end of string or whitespace
autocomplete now searches namespace, so entering 'char' will load up all the 'character:' tags along with 'series:di gi charat'. this can lag to hell and back, so it may either need some work or be optional in the future. feedback would be appreciated
typing 'namespace:' will include all the series tags below the special optimised 'namespace:*anything*' tag
autocomplete searches recognise an explicit '*' no matter where it is in the entry text. typing 'a*' will load up all the a tags and present a 'a*' wildcard option
quickly entering a wildcard entry will now submit the correct wildcard predicate ('rather than a literal 'hel*' or whatever tag)
review services panel now reports total mappings info on tag services
review services panel now reports total files info on file services
manage services's listctrl is now type | name | deletable and initially sorts by type. the strings used for hydrus service types are also improved
manage serverside services (called by server admins to manage their services) have fixed setnondupe port and name on edit service events
new popup messages will now also appear if there were previously no popup messages to display if the current focus is on a child on_top frame, such as review services (you'll now see the processing popup appear when you click 'process now' on review services)
the popup message manager now initialises its display window with a single message that is quickly dismissed. this helps set up some variables in a safe environment so they don't have to be generated later when the gui might be minimised or otherwise unusual
hid hydrus update files from 'all local files' searches
added 'media_view' entries for hydrus update files, just in case they are still visible in some unusual contexts (and they may be again in a future update anyway)
fixed 'recent tags' being returned from the database out of order
by default, 'recent tags' is now on for new users
'get tags even if file already in db' now defaults to False
file import status now allows a 'delete' action below the 'skip' action
file import status right-click event processing is more sane
fixed the new raw width/height sort choices, which were accidentally swapped
cleaned the media sort code generally
cleared out some redundant rows that are in some users' client_files_locations
namespaced predicates are no longer count-merged with their namespaceless versions in 'write' autocomplete dropdowns
'unknown' accounts should now properly resync after clientside service change
improved how registration keys are checked serverside when fetching access keys
fixed a v244 update problem when unexected additional tag parent/sibling petitions rows exist
improved my free space test code and applied it to the old v243->v244 free space test (it'll now test free space on your temporary path and report problems appropriately)
to improve log privacy and cleanliness, and to make it easier to report profiles, db/pubsub profiles now write to a separate log file named appropriately and labelled with the process's start time
profiles are more concise and formatted a little neater
across the program, three-period ... ellipses are now replaced with their single character unicode … counterpart (except to the console, where any instance of the unicode ellipsis will now be converted back to ...)
cleaned up some log printing code
cleaned up some experimental static serialisation code, still thinking if I like it or not
started on some proper unit tests for hydrus serialisable objects
fixed and otherwise updated a heap of unit test code to account for the v245 changes
cleaned up a bunch of old database table join code
started some databse-query-tuple-stripping code cleaning
deleted more old unused code
misc timing improvements
misc code cleanup experimentation
misc cleanup

version 245

fixed a v244 update problem for clients updating from<v238< li=""></v238<>
some misc stuff:
if you start editing many subscriptions, cancelling a single dialog will break the chain of loading new dialogs
reduced some redundancy in regular client file import
improved how the dialog for selection from a list of strings works
if the client ever merges one directory to another (such as in external file locations migration) and any files fail to merge, the source will no longer be deleted
created new flexible bandwidth tracking and ruling objects
updated how repository updates work, splitting the old explicit and self-contained content update package system to a new implicit definitions/content split system and an improved one-step-sync metadata propagation
updating now takes approximately 23% as much bandwidth as before
update files are now stored in client_files and server_files like any other file (client_updates and server_updates folders will be deleted on update)
the server will print update generation info to its log
unfortunately, updates cannot be converted, so a complete resync of update files is required. the smaller update size and better bandwidth controls should mitigate the problem somewhat
the server has been compacted across all content types--its mappings db file should shrink about 12%
due to new service-specific ids, server.master.db should increase in size, typically about 50%
harmonised how GET and POST/response args are built and parsed across the network
server administration initialisation is now simpler, done with 'init' registration key
leading and trailing spaces are now removed from both the namespace and subtag components of namespaced tags, meaning 'title: blah' will be collapsed to 'title:blah'. tag repositories will clean their existing tags on update
invalid serverside tags will be replaced with valid placeholders on server update
refactored, harmonised and simplified some server request code
Eris makes a triumphant return to the root welcome page ('/' request of any service) with improved self-description text as well
updated how bandwidth is tracked and overseen
all requests now consume bandwidth
fewer requests are actually constrained by bandwidth--at the moment, it is only update files and file/thumbnail downloads, as these represent the overwhelming majority of bandwidth consumption and are not at all critical to service operation--this may change in the future, but it suits our purposes for now
bandwidth tracking code is more sane across the board
the server's administration service now tracks server-wide bandwidth as it happens
service and server-wide bandwidth rules are consulted as soon as the request begins
improved some server response rendering
permissions are more flexible and content-specific
improved how file repositories check and process file requests
created a gui control for managing bandwidth rules
updated the serverside service object
the serverside service object now contains bandwidth rules and tracking
updated how the server deals with services on a db level

updated how the server deals with account types on a db level
converted clientside server account type management gui to the new panel system
updated gui code for clientside server account type management
serverside account types are now fetched from a cache, reducing memory sprawl
updated the account object
the account object now contains a bandwidth tracker
updated how the server deals with accounts on a db level
updated the clientside server object
the clientside server object now contains bandwidth rules and a tracker and has improved error management, recovery, and reporting
updated how the client deals with services on a db level
improved how serverside bandwidth errors are caught
all clientside services start with a 50MB/day bandwidth limit
existing repositories will get a 250MB/month, 50MB/day default bandwidth limit, just to help us get over the hump--see the release post for info on how to get all the updates anyway
updated manage services dialog extensively
service account registration now occurs through a simple button on the normal clientside service edit panel
all services can now be renamed
updated the content processing pipeline
prepared code for future merging of file and tag repositories
added future support for pend-petitions for files and mappings and simple creation permissions for tag siblings and parents
the clientside content processing pipeline now operates inside a single database transaction, reducing a great deal of previously redundant hard drive activity
the serverside content processing pipeline now creates per-service timestamped content definitions
the clientside content processing pipeline now maintains and appropriately consults a cache for server definitions
pre-process disk cache is more intelligent
updated review services to match the new service objects
service review panels now show more information about error state and so on
service review panels should now update as soon as services change
you can now force sync repositories from review services
you can now pause/resume repositories from review services
you can now export repository update files from review services
you can now import repository update files from the services menu

most service-specific panels on manage services
petition resolution
serverside account modification, including banning

version 244

updated client database to compact ( namespace_id, tag_id ) pair into a single id for storage
added some bells and whistles to the update code
added a free space check and messagebox warning before the update
updated db, service, and a/c cache creation code to reflect new schema

improved scheduling of how files are physically deleted
numerous laggy temp_table replacement/cleanup
more temp_table replacement
misc efficiency improvements and general db code cleanup
misc path code cleanup

version 243

updated more menu code to the new system
finished updating all main gui menubar and thumbnail menu code
all brackets, braces, parentheses, and single and double quotes are now ignored when matching search text to tag. inputting 'mercy' matches 'character:angela "mercy" ziegler' and entering '[[[intensifies]]]' matches '[intensifies]'
'*' searches will now return no autocomplete results, rather than trying to load absolutely everything
made wildcard searching significantly more permissable--it now implicitly applies a '*' to the beginning as well as the end of your search input
the main gui's notebook pages will now be disabled while a session loads
might have fixed a first-boot layout issue--otherwise added a layout entry to the debug menu for further testing of this problem
improved progress layout on file import dialog
created a more efficient way for threads to update gui elements
the file import dialog uses this new update system and parses lots of small files much faster as a result
the edit import folder dialog will now complain if you try to put in an import path that includes the install or db directory
ffmpeg mime parsing now catches and reports audio formats without any hassle
thread downloader no longer fetches file extension in filename tag 'filename:blah' instead of 'filename:blah.jpg'
changed png default zoom rules to copy jpg--the unusual zoom as default was more confusing than helpful
updated sqlite for windows--should be a decent bit faster
deleted a lot of old code that'll never be needed again
misc refactoring
misc cleanup

version 242

optimised 'exact match' similar file queries to run a lot faster
optimised similar file queries in general, particularly for larger cycle queries
optimised hamming distance calculation, decreasing time by roughly 45%!
the similar files tree maintenance idle job will not trigger while there are phashes still to regenerate (this was redundantly and annoyingly blatting the new dupes page as soon as phash regen was paused)
removed similar files tree maintenance entry from db->maintain menu, as it can be done better from the new dupes page
adjusted the duplicate search and file phash regen progress gauges to reflect total number of files in cache, not the current batch job
all maintenance jobs on the duplicates search page will now save their progress (and free up a hanging gui) every 30 seconds
the duplicates page's cog menu button now lets you put phash regen and tree rebalancing on the normal idle routine, defaulting both to off
the cog menu can also put duplicate searching on idle time!
added a very rough 'just show me some pairs!' button to the dupe page--it is pretty neat to finally see what is going on
I may have reduced the memory use explosion some users are getting during file phash regen maintenance
wrote an unclose_page action and added it to the shortcuts options panel--it undoes the last page close, if one exists. ctrl+u will be the default for new users, but existing users have to add it under options
added ascending/descending sort choices for width, height, ratio, and num_pixels
the client can no longer talk to old http hydrus network servers--everything is now https
in prep for a later network version update, the client now supports gzipped network strings (which compress json a lot better than the old lz4 compression)
fixed gif rendering in the Windows build--I forgot to update a build script dll patch for the new version of opencv
the export file dialog's neighbouring .txt taglist file stuff now allows you to select a specific combination of tag services
if an hdd import's original file is due to be deleted, any existing neighbouring taglist .txt file will now also be deleted
the inter-thread messaging system has a new simple way of reporting download progress on an url
the handful of things that create a downloading popup (like the youtube downloader) now use this new download reporting system
sankaku seems to be 503-broke due to cloudflare protection--I have paused all existing sankaku subscriptions and removed the sankaku entry for new users (pending a future fix on my or their end)
I've also removed danbooru for new users for now--someone can fix the long-running sample size file issue in the new downloader engine
removed unnamespaced tag support from the hentai-foundry parser--maybe someone can try to fix that mess in the new downloader engine
menubuttons can now handle boolean check menu items that are tied straight into hydrus's options
menus launched from the newer frame and dialog code will now correctly display their help text on the main gui frame's statusbar! (at least on Windows! Linux and OS X remain borked!)
fixed a unicode error parsing bug in the gallery downloader
the server stop (or restart) command now correctly uses https!
the server test code now works on https as appropriate
fixed some misc server test code
misc fixes
misc cleanup
misc layout cleanup

version 241

fixed the 'setnondupename' problem that was affecting 'add' actions on manage subscriptions, scripts, and import/export folders
added some more tests to catch this problem automatically in future
cleaned up some similar files phash regeneration logic
cleaned up similar files maintenance code to deal with the new duplicates page
wrote a similar files duplicate pair search maintenance routine
activated file phash regen button on the new duplicates page
activated branch rebalancing button on the new duplicates page
activated duplicate search button on the new duplicates page
search distance on the new duplicates page is now remembered between sessions
improved the phash algorithm to use median instead of mean--it now gives fewer apparent false positives and negatives, but I think it may also be stricter in general
the duplicate system now discards phashes for blank, flat colour images (this will be more useful when I reintroduce dupe checking for animations, which often start with a black frame)
misc phash code cleanup
all local jpegs and pngs will be scheduled for phash regeneration on update as their current phashes are legacies of several older versions of the algorithm
debuted a cog menu button on the new duplicates page to refresh the page and reset found potential duplicate pairs--this cog should be making appearances elsewhere to add settings and reduce excess buttons
improved some search logic that was refreshing too much info on an 'include current/pending tags' button press
fixed pixiv login--for now!
system:dimensions now catches an enter key event and passes it to the correct ok button, rather than always num_pixels
fixed some bad http->https conversion when uploading files to file repo
folder deletion will try to deal better with read-only nested files
tag parent uploads will now go one at a time (rather than up to 100 as before) to reduce commit lag
updated to python 2.7.13 for windows
updated to OpenCV 3.2 for windows--this new version does not crash with the same files that 3.1 does, so I recommend windows users turn off 'load images with pil' under options->media if they have it set
I think I improved some unicode error handling
added LICENSE_PATH and harmonised various instances of default db dir creation to DEFAULT_DB_DIR, both in HydrusConstants
misc code cleanup and bitmap button cleanup

version 240

improved how the client analyzes itself, reducing maintenance latency and also overall cpu usage. syncing a big repo will no longer introduce lingering large lag, and huge analyze jobs will run significantly less frequently
the analyze cache will be reset on update, so you will have one big round of analyze the next time you maintain, and then you are good
added data structures to support auto-discovery of duplicate files
improved how some similar files maintenance occurs
flushed out duplicate status reporting
added a new page type, currently under pages->search pages->duplicates, to handle duplicate discovery and filtering
created a gui skeleton for the new duplicates page
started some handles and update code for the new duplicates page
wrote a new txt file in the db dir about the new emergency extract scripts
wrote an emergency extract script to migrate subscriptions to a new db
wrote an emergency extract script to migrate options to a new db
the trash clearing daemon now runs in the foreground, and a little of its code is improved
the trash clearing daemon now makes a popup message when it does work
the server's ssl keys are now set to read-only on Windows and user read-only only (i.e. chmod 400) on Linux and OS X on creation and update
added a explicitly unicode popup message to the debug test
fixed some network error catching code that was using Windows-only error codes
converted more of the thumbnail right-click menu over to the new system

the new listctrl can now quickly fetch item index from the underlying object
the file import status panel should now cope with extremely huge lists a bit better now!
multiple parsing child nodes can now import from/export to clipboard as lists
export folders now have names, so you can have multiple export folders pointing to the same path! existing export folders will get their path as their name, but this can be changed no prob
cleaned import/export folder dialogs
cleaned import/export folder dialog workflow
several misc import/export folder improvements
hydrus servers are now exclusively https with self-signed certificates
hydrus servers now create server.crt and server.key in their db folders for SSL--these files will be backed up along with everything else on an admin backup command
system:hash now ignores the file domain and any other predicate. it now returns very quickly, no matter the context
improved system:hash search logic
all the awkward choice dropdowns in system predicate panels are replaced with radioboxes
improved system:rating panel grid layout
wrote a better subclass of radiobox to handle more data
moved first half of thumbnail menu to new menu system
cleaned up a little thumbnail menu logic
improved the different ways services are added to thumbnail menu
thumbnail 'select' menu is logically cleaned up and allows for better file domain selection
the thumbnail menu's copy files and copy hashes to clipboard will now send them ordered (they were previously pseudo-random)
added 'paths' to the share->copy thumbnail menu for copying multiple files' paths. these are also ordered.
if the popup message manager does not have any errors, it will no longer unhide (which can annoyingly raise the main gui window) when the gui window does not have focus
removed some old redundant error reporting stuff in popups
improved and quietened some some mime detection failure code, sped up mime failure loop in all cases
massively simplified and atomised how new serialisable-object management panels can save their data
the manage subscription dialog now saves in a single, faster transaction
the manage script dialog now saves in a single, faster transaction
reduced redundant index work from analyze jobs

fixed media removal rules when deleting from the 'all local files' domain
polished and clarified some of the help's tag schema

more misc refactoring

version 238

added left/right equal ratio preference to the similar files search tree generation
added high standard deviation preference to the similar files search tree generation
added 'db profile mode' to the help menu, for briefer profiling in future
when a similar files search occurs with db report mode on, it'll popup a nice bit of text saying how many cycles it took
fixed a bug due to last week's 'all local files' change that meant archive/delete filtering would include any selected trashed files
'recent tags' will now only be populated by add/pend tag events, and only by those tags that were valid for that action
moved the help menu to the new menu system
added bitmapped menu item support to the new menu code
fixed and cleaned up some of the new menu code
improved a/c cache regen error reporting

version 237

added 'all local files' service that spans all local file domains
improved trash service code
trashed files now report their trashed timestamp in right-click menus
trash views will sort oldest/newest by the trash timestamp
renamed 'local files' to 'my files' to reduce initial confusion
if you don't like 'my files', you can now rename the local files service under manage services!
improved how some local file service metadata is stored
cleaned and possibly fixed up some delete code
cleaned up a bunch of misc service and file service code
the client is more intelligent about what local files are -- you can now 'open externally' trashed files, for instance
on multiple monitor systems, the new sizing system now bounds itself by the appropriate monitor's dimensions (previously, it was always consulting the primary, I think)
if an expansion event causes a frame to grow off screen, the new sizing system will now attempt to move it up and left so it is completely visible
fixed an important bug in the specific service autocomplete cache that was leading to several kinds of miscount--please regen your autocomplete cache at your convenience
the client can now post additional messages on boot (you'll see one!)
improved how errors with unusual characters are applied to failed import file status objects
left double-click on the main gui greyspace now opens the new page chooser as well
restored session pages now recover more gracefully from missing services
shortened the 'stop after this many files' phrase, which was mis-sizing downloader panels

added ffmpeg, python, and sqlite versions to the help->about window
harmonised daemon code
added a new class of daemon that will not fire while a session load is occuring
subscriptions, import and export folders, and file repo downloads now use this new daemon
cleaned the way background daemons check for idle

time deltas (like on subs edit panel or a thread watcher) now render more concisely ('7 days' instead of '7 days 0 hours')
serialisable object png export panel now has a width parameter
fixed a bug where tags that begin with unicode digits were accidentally identifying as numbers for the purposes of sorting and throwing errors on convert fail
the media viewer can handle some more unusual content update combinations--for instance, if it cannot figure out which media to show next, it will revert back to the first image rather than displaying an undefined null mess
updated and cleaned a bunch of my old misc encryption code
misc cleanup

fixed linux manage tags text input
reduced incidence of linux media viewer post-manage tags key event swallowing
fixed an issue where if the manage tags dialog was launched from the media viewer while a hover window was displaying, the main gui would often be raised when the manage tags frame was closed, annoyingly obscuring and de-focusing the underlying media viewer
fixed manage tags action workflow when no valid tag choices exist
entering a tag petition reason now has several common 'suggestions' for quick entry

improved how the new GET request read reattempt works
cleaned up some spammy error code
cleaned up spammy test code
misc error handling improvements

fixed non-null ratings changes in the numerical ratings dialog
fixed culling and adding variables not initialising on the edit html formula panel

the 'too many redirects' error message is expanded to print the url called and its redirect request
errors from trying to delete files in use by another process will no longer make popups--they'll just write a note in the log

misc fixes

version 227

both the client and server now use standard command line input and will produce a proper help with a -h switch (although the 'windowed' frozen client executable can't print back to console)
both the client and server now support a -d or --db_dir to set a db directory outside of the install directory. you can now run multiple clients off the same install!

added an option to automatically 'hide' the popup message manager on main gui minimise (which has patchy multiplat support--some mindow managers don't do this automatically, some do but break when you force it)
added an option to automatically hide the popup message manager on main gui dofocus, which may help with window managers that minimise to the system tray, which wx cannot detect

fixed a bug when performing a 'go!' action in the advanced content update panel when 'local tags' is the only tag service

version 222

replacing the previously basic zoom_in_to_canvas, the zoom options now support 100%, max regular zoom, or canvas fit for scaling up and down and for the media and preview windows!
cleaned up some garbage zoom code
refactored and harmonised how default zooms are calculated
harmonised and improved how canvas zooms are set

files added through the normal import dialog or import folders will be not be fed into the import pipeline if it looks like they are already in use by another process
(hence setting an import folder to a browser download destination should be more reliable)
rewrote some critical phash generation code that was running extremely slow when importing large pngs with transparency
all listctrls that have an edit button now also trigger the edit event on item activate (e.g. double-click/enter key on an item)
added zoom in/out/switch to edit shortcut action dropdowns, can't promise it works everywhere
'stopping' a gallery page search will now correctly make sure the search queue is unpaused so it can move on to any subsequent search

directory creation is improved across the program
fixed the optimised merge-move file code, which was forgetting to clean up the source when no move was needed

manual exports, which use copy rather than move, should also be more sensible and faster when repeated
improved database exception rendering, which in some cases was being truncated
misc cleanup
misc small updates to help

fixed false positive shutdown maintenance checking due to vacuums projected to take longer than the given maintenance time
fixed false positive shutdown maintenance checking due to sqlite_stat1 creeping in
pasting tags or otherwise editing many in at once in the manage tags frame will immediately commit all the changes in one db transaction, rather than one for each tag laggily in turn

open externally and embed buttons now use hand cursor
the simple path tagging dialog panel now cuts off .jpg extensions from filenames on filename parse
if the string component of a generated file export path already ends in the correct .jpg extension, a second will not be added
ipfs unpin will no longer break if the file was already unpinned
the hydrus server now gives filename (for a file save as dialog) correctly on a content-disposition header (this affects the client's local booru as well)

fixed missing recalculation of scrolledpanel's virtualsize after child wx.notebook's page change
fixed bad parentage for file import status frames

updated to Pillow 3.2.0
misc cleanup

version 211

added options for disk cache init and maintenance to 'speed and memory' page of options
abstracted the manage tags dialog into a general purpose 'apply' dialog and a scrollable manage tags panel
the 'auto-replace entered siblings' checkbox now remembers how it was last set
uncertain sibling tag counts will now appear like 'tag (1,234-1,456)', showing the range of possible results they represent
fixed a bug where siblings would be collapsed inside the tag manager object if a specific tag search domain was set
altering the search text on an autocomplete from 'tag' to '-tag' or vice versa should graphically update more reliably, and an exact-matching predicate will be promoted to the top of the list correctly either way
calls to upnpc will now kill the process and raise an exception if it hangs for more than thirty seconds
misc improvements and cleanup

a full disk cache population now runs before repo sync
the client now keeps about 200MB of itself in the disk cache during idle maintenance
the update files in client_updates are now stored compressed
the log files and 'already running' files are now stored in the db folder, meaning hydrus shouldn't have to write to anything but db dir and temp dir

the log directory is no longer needed
if there is only one booru to select, it will be auto-selected
client failed exit is less likely to hang, more likely to log error

server thumbnails are similarly merged into server_files
to keep things simple, the client no longer keeps track of number of local vs. remote thumbnails for file repositories
perceptual hashes are now calculated from original file, not thumbnail, and only for jpegs and pngs (videos had too many black frames etc...)

client will more aggressively vacuum and analyze if the client has been idle for an hour
client vacuum now prints success statements, with duration, to the log
analyze now produces an auto-dismissing vacuum-like popup message
the 'is maintenance due' check on shutdown now accounts for the new vacuum logic and includes analyze needs as well

any tag service deletion or reset should now only take a few seconds
fixed a physical file deletion bug that seems to have affected (some?) versions of linux and os x
reintroduced a revamped 'clear orphans' database->maintenance routine for the client, which will delete or move orphaned files and delete orphaned thumbnails. run this if you are on os x or linux
improved misc file deletion code
fixed some multiplatform path conversion, and generally improved how paths are stored and retrieved
the network application of a parent tag to all files with the child tag now happens serverside, and only on petitioner-approval of a tag parent relationship. it still occurs locally to the uploader, but is now wrapped up in the parent commit
fixed some numtags search logic
fixed an issue when mixing system:age with any tag-based predicate
media_results db calls no longer require a file domain
'hide inbox and archive preds if either has no files' now defaults to off
added an option to disable OpenCV for gif rendering
the selection tags panel now initialises with the correct tag domain (it was previously always starting as 'all known tags', which is not always true for session pages)

version 203

thumbnail resize now happens on the fly--feel free to change it as often as you like, it takes no time at all
added 'lexicographic (grouped by namespace)' tag sorting to the selection tags box
added an option to disable OpenCV for static images under the media options page
panning with the shortcut keys now pans by a twelfth of the media size or canvas size, whichever is smaller
cleared the analyze timestamp cache for both client and server, which will force a reanalyze of the new db files on the next db maintenance run

the server now analyzes attached database files
improved an unhelpful server thumbnail error message
added an invalid NULL check-and-skip to hash cross-referencing

updated sqlite for windows
misc cleanup

version 202

fixed a problem with the v198->v199 update step
added a bad error catch in the vacuum step in v200->v201
added some rollback exception handling for unusual situations
the autocomplete caches under the client_cache subdirectory are dynamically folded into a single client.caches.db file, and that file is folded into the main db journal like the other attached dbs
ac_cache file and tag processing lag and edge-case autocomplete miscounting should be removed as a result
cache generation is optimised for empty services
specific file_caches' add and delete file commands now modify their tables directly, saving a whole load of time that was previously done superfluously filtering
the specific ac_caches' add mappings command is a bit more logically efficient
increased cache size for each attached database
folded all 'attached' db update code into the main update_db routine
folded all 'attached' db init code into the main create_db routine
made the vacuum checking routine safer
reduced analyze log spam
analyze maintenance breaks its larger jobs up better
analyze mainenance now analyzes external databases
the db connection now refreshes every half hour, to regularly clear out journal files
the hydrus db assumes it generally has exclusive control over its db, so it no longer wraps its read-only requests in transactions
session load now happens off the main gui thread, and media generation is broken into 256-file chunks, which reduces startup db and gui lag for large sessions
the youtube video downloader now lists a webm option if youtube provides one (they seem to offer 360p webms on everything(?) now)
the timedeltacontrol (where you set the period for the thread checker and import folders and so on) is replaced by the more compact timedeltabutton, which will launch a dialog with the old control when clicked
the server will no longer revisit old updates and cull since-deleted content, as this was proving cpu-burdensome and not helpful to future plans for update dissemination, which will rely on static update files
misc cleanup of some server db stuff
content update processing will not spam menu updates throughout, but only notify once at the end, which should reduce idle gui hang due to db access choke
the autocomplete tag entry will not refresh system pred menu during idle, which should reduce idle gui hang due to db access choke
shutdown repo sync will now report the update summary text and will not spam the intervening statuses to the log
moved timestamp out of the serviceless media_result and into the locations_manager, to reflect the database's knowledge of each current service having a different timestamp
local and trash timestamps are generated from the locations_manager now, and non-local file service timestamps will soon follow (e.g. 'pinned to ipfs_service 3 days ago')
if the timestamp is unknown for the current service context, it will not be displayed
file repositories will now only sync thumbnails when their updates are completely synced (to stop 404s from since-deleted files)
fixed a ( 0, 0 ) resize event bug that was sometimes causing borked media containers on media viewer shutdown
syncing to a sha256 tag archive will still import the data as requested, but a popup note will explain that as everything will be imported, further syncing is pointless., and the sync will not be saved
fixed a bug in hta export if you click cancel on the hash_type choosing dialogs
misc cleanup

version 201

exported hash and tag master tables to external database files for both client and server
the client's 'mappings' table is split into 'current_mappings' and 'pending_mappings', saving about 20% of space and speed for almost all mappings operations

removed superfluous rowid column from server mappings tables, saving about 20% of space
to save time, service mapping counts now only aggregate current mappings, not current and pending
exporting to tag archive now only exports current_mappings, not pending

cleaned up a lot of mapping-related query code, and any ugly status leftovers from current/pending union
num_namespaces is no longer tracked for tag services
unified clientside service deletion code, fixing several orphan-generation issues
db update will remove all mappings orphans created by a recent tag service deletion
some db settings init is harmonised into one location

this nice new line is printed to the log as a record of repo sync rows/s speed
the client will shut down faster if big jobs are running

cleaned up some image/animation container init code
cleaned up some image cache image tracking code
fixed ipfs pin, which was conflicting with the new ac caches
extracted client deleted_mappings to their own db table
prepped mappings processing to work with status-separate mappings tables--it is also a lot cleaner now
because of the deleted_mappings extraction, a bunch of mappings membership tests are much simpler now
upped the db cache size to a semi-ludicrous 150MB, which nonetheless seems to improve processing speed
improved how hydrus databases manage their db file locations
improved how the client and server databases backup/restore
improved some non-local thumbnail fetching code
converted some old YAML stuff to JSON
improved big job polite pausing code
cleaned up some clientside imports, and set the client to only import its server code if it needs to boot a local service
when an import folder needs to rename a file it is about to move because of a conflict, it will now add autoincrementing numbers, starting at 0, and before the file extension
added some missing shortcut actions (pan_x and set_media_focus) to the shortcut input entry dialog
tags and siblings that match the current WRITE autocomplete tags entry will no longer have doubled parents!
improved how system:limit is applied to searches
