Site Update Log

2017-12-12

- The forums was updated to use reCAPTCHA v2. Let me know if you encounter any issues with this.


2017-12-11

- The new Autotagger system is now live. This will automatically sweep over older galleries and clean up/replace tags to match the current tagging standard. These retags do not affect tagging stats.


2017-11-25

- Corrected an issue where upload errors weren't always displayed.


2017-11-08

- Renaming galleries that were posted more than 24 hours ago now requires a rename petition. The name can still be changed as part of a gallery update.


2017-10-29

- Reclass tag votes will now be automatically pruned from galleries that have had no such votes for 30 days. Galleries are still locked to the highest voted category at the time, and a new reclass tag is required to change it. This does not affect tagging stats.

- Redundant votes for tags that are slaved to reclass tags are pruned without any grace time.


2017-10-27

- Some additional redundant tags will now be automatically pruned from the system - specifically, "misc" tags that have no visible usage and that are grouped with a namespaced tag with the exact same name. There were a few hundred of these in the system, and they were not useful for anything.


2017-10-26

- Corrected an issue with internal statistics gathering for tags that left some tags with an inconsistent or missing usage tally, which made those tags only searchable for exact matches.


2017-10-13

- Added some archiver reliability improvements to work around some recent issues connecting to other servers. (Update: Corrected a regression where some archiver links were not working.)


2017-10-11

- The BTC rate calculations no longer use BitcoinCharts due to some persistent API issues. We now use a combination of Bitstamp's volume-weighted daily average and CoinMarketCap's current average of all exchanges, plus the customary 10%. The new rate calculation will quickly catch up to increases in the exchange rates, but has an internal decay that, in case of major downwards fluctuations, caps rate reductions to no more than 0.1% per hour.


2017-10-02

- The old upload lock was not sufficiently reliable to prevent issues when aggressively uploading files to the same gallery in multiple tabs, and has been replaced with a proper lock. Note that this is not recommended, and if you do start multiple concurrent uploads to the same gallery, you can never be sure that the uploads will be processed in the order you start them.


2017-09-16

- DNP keywords should now never prevent tag searches for unrelated tags.


2017-09-14

- Minor improvements to the H@H initial speed testing. This should help with potential issues when slow clients and clients with poor connectivity to the RPC servers have a high configured throttle, by dynamically adjusting the test size. (1.3+ only)


2017-09-12

- Corrected a regression where some H@H clients would fail to start up.


2017-09-09

- Improvements to H@H client speed discovery by taking long-term overload data into account.


2017-08-28

- If you previously had a Bitcoin address generated, you may notice that the displayed address has now changed due to an internal change in the address type we use. As always, previously generated addresses will keep working.


2017-08-22

- Fixed a validation issue where a small subset of Bitcoin addresses would make the QR code generator fail. (Copying the address itself would still have worked fine.)


2017-08-18

The H@H status readout has been reworked.

- The "estimated" network capacity and utilization has been removed, as it didn't really show anything relevant, and certainly didn't show what most people would think.

- A H@H Miss% readout has been added. This is the percentage of requests that would have gone to a H@H client if one was available, but where none could be found. During the peak load of a region, this is by far the best indicator for whether a region needs more clients or not. Anything above ~0% during peak hours means more clients are genuinely useful.

- Global stats are now calculated for all metrics.


2017-08-17

- Corrected a regression with gallery search pagination when certain filter options were used.


2017-08-07

- Tag moderators now have the ability to rename tags. Details are found here for people this applies to.

- Tag changes that affect the gallery tag pane should now always reset the affected caches to prevent stale information from being displayed.

- When searching in exact mode, such as with the /tag/ URLs, slave tags now also return matches for their master unless ?skip_mastertags=1 is appended to the URL, in order to preserve existing searches when doing renames.


2017-07-27

- The tagging system was reworked to operate on chains of galleries. This is mostly relevant for taggers, so the notes can be read here.


2017-03-12

- The H@H Downloader now uses the same filename collision avoidance/order preservation algorithm as the archiver. Meaning, it will prefix all filenames with the page number unless all the filenames are unique and the file order is the same as both the regular and natural sort order. (This is a server-side change and does not require a client update.)


2017-03-10

- The bitcoin system will now automatically create a new wallet address for you if the previous address was used and it's been more than 24 hours since it was generated.

(Old addresses are never invalidated and you will always be credited on any of the addresses ever generated for you, but address reuse is generally discouraged for security and privacy reasons, so we recommend using the newest one every time.)


2017-03-04

- Bounty rewards from people other than the poster now also lock in after 15 minutes, and can then only be rescinded after a month or if the bounty is cancelled.

- Bounty results was bumped up from 25 to 50 results per page.


2017-03-02

- Gallery rename votes are no longer allowed unless the vote challenges the top rename, or the last vote was made fairly recently. This prevents ghost votes on old renames. (The old vote cap of 200 or next highest rename + 100 is still in place.)


2017-03-01

- H@H download GP costs now always has the donator discount applied regardless of donation status.

- Corrected an issue where starting a H@H download would also unlock an archive download.

- The "Get External Gallery" code generator functionality was retired. It was barely being used, and nixing it makes some future changes far easier.


2017-02-27

- Galleries is currently testing out Cloudflare for frontend reverse proxying. This will take effect over the next 24 hours.


2017-02-22

- Internal and public XHR/API usage was moved to the separate api.e-hentai.org subdomain. This shouldn't visibly affect anything, but let me know if you run into any unusual browser-specific CORS/same-origin restriction issues.


2017-02-19

- Corrected an issue when changing orientation on mobile devices where images could end up squished to a thin line when in a specific viewing mode. This was caused by a variable name collision with one of the ad scripts.


2017-02-15

- Corrected a rare replication timing issue that could cause deleted favorites to linger in a glitchy way after the favorite page reloads.


2017-02-13

- The improved geolocation was pushed to the main cluster, which among other things adds IPv6 geolocation and thus removes one of the blockers for rolling out IPv6 support.

- An improved gallery report system was added. This primarily clarifies what kind of information is required for different kinds of reports, making it easier both to submit and review reports. It also lets you view and edit recently submitted reports, and will automatically prefill some fields if you previously submitted any reports.

- The "low power" tag search option will no longer expand the search with tags that have no visible usage, as these would cause the search engine to run out of memory for some search terms.


2017-02-09

- The poster of a bounty now gets a slightly different bounty screen, without the claim dialog that they cannot use, leaving more room for the rewards and claims.

- Additional rewards added by the bounty poster are now locked in after a 15 minute grace period. These can then only be rescinded by cancelling the entire bounty.

- When a bounty acceptance is flagged as Reserved, existing rewards are now locked in. New rewards added while the bounty is in the reserved state will also be locked in after a 15 minute grace period. This lock is released if the reservation is withdrawn or removed.


2017-02-08

- Some improvements to IP geolocation are currently being tested on the H@H servers. Let me know if this flips any previously correct locations to a wrong one.


2017-02-07

- Corrected an issue where some torrent files weren't available when they should be.


2017-02-06

- As the Firefox issue has been mostly fixed, we are no longer blocking H@H clients prior to 1.4.1 from starting up. As such, 1.2.6, 1.3.x and 1.4.0 will work again, but we're still recommending that everyone updates to 1.4.1, and older clients will still be flagged as "outdated".


2017-02-05

- Torrent file downloads are now fully HTTPS. The additional redirect to repo was also eliminated.

- H@H clients that maintain a quality low watermark of at least 7000 can now go past 5000 static ranges, up to a new limit of 6000.

- Similarly, we now require a quality low watermark of 3000 to go past 1000 ranges, and 5000 to go past 2000 ranges.


2017-01-29

- Added a warning to the H@H page if you have any outdated clients currently active.


2017-01-28

- Corrected a problem with the uploader's folder manager where the display order could start shuffling around if you had 10 or more folders.

- Hentai@Home 1.4.1 is now the minimum version required. Older clients have to update at the next restart. (Usually older clients would be allowed for far longer, but the Firefox fail makes it somewhat urgent, and they aren't planning on patching their screwup any time soon.)


2017-01-24

- The switchover is now in full effect, and old links should now all be redirected. Let us know if something points to the wrong location.


2017-01-21

- Galleries was moved to the root level domain, and switched to HTTPS. The old g.e will soon start forcing redirects there.

- The MPV now has a minimum 500ms delay between each image dispatch request, to prevent the frontend DDoS protection from temporarily blocking it when scrolling very fast or loading a page with many small images.


2017-01-11

- Corrected an issue where a Bitcoin transaction that had multiple outputs to addresses in the EH system would only have one of the outputs credited. (This only affected two transactions ever.)


2017-01-10

- H@H 1.2.6 is now the lowest supported version. Clients older than 1.2.6 will have to update when they are next restarted. (1.4.0 is the current and recommended version.)


2017-01-09

- The new uploader was deployed. Changes can be found here.


2017-01-05

- The throttle for H@H clients can no longer be set to higher than 2000000 KB/s (2 GB/s) to prevent an out-of-bounds integer.


2017-01-01

- Fixed an issue where generating folder BBCode for galleries in the "Unsorted" folder didn't work.

- Added an repeated auto-reload check to the MPV to prevent retarded browser extensions from getting people banned.

- Long gallery names should no longer cut off the Japanese script name on the gallery page.

1.4.2

- Fix for broken backwards compatibility in Java 9 by removing dependency on module javax.xml.bind.DatatypeConverter, which prevented H@H from working without manually loading the module.

- Previously, when shutting down, the client would immediately stop receiving new HTTP connections, then wait 25 seconds before exiting. Now, the client will wait five seconds before closing the socket, then shut down as soon as all pending requests have completed or when 25 additional seconds have passed. This will generally result in both faster and cleaner shutdowns than before.

- If the client was terminated between initializing the cache and finishing startup, the cache state was not saved and a full rescan would be required. This should now be fixed.

- If the client errored out from the program's main loop, most commonly when running out of disk space, the cache state might fail to save depending on thread interrupt timings. This should now be fixed.

- The specific failure reason should now always be printed if startup tests fail.

This is an optional update; unless you are having any particular issues, updating is not required.

To update an existing client: shut it down, download Hentai@Home 1.4.2, extract the archive, copy the jar files over the existing ones, then restart the client.

The full source code for H@H is available and licensed under the GNU General Public License v3, and can be downloaded here. Building it from source only requires the free Java SE 7 JDK.

Recent release notes: 1.4.1 - 1.4.0 - 1.3 Experimental Branch
Posted Friday, 27th of January 2017, 12:03 UTC
- Malformed requests such as those made by Firefox 51 are now detected and terminated early, rather than having the connection sit around and wait for the normal timeout.

- To save some CPU time, the GUI will no longer call for a repaint every time the stat readouts change. Twice per second should be sufficent.

- Updated some URL readouts to use the new HTTPS URLs.

This will become a required update very soon. Note that because of the issues caused by the non-conformant behavior of Firefox 51, we will also be retiring the 1.2 branch earlier than planned. If you are still running on the 1.2 branch, you will want to update to 1.4.1 ASAP.

Recent release notes: 1.4.0 - 1.3 Experimental Branch
Posted Saturday, 21st of January 2017, 10:41 UTC
As part of the shift towards moving the rest of the site to HTTPS, there will be some changes to the URL structures over the next few days. Most importantly, the "old" E-Hentai that hasn't been maintained for years will finally be retired. Galleries will drop the g. and host directly on the e-hentai.org root domain. Old links should redirect to the new ones wherever possible.

Generally this process should be transparent, but you may encounter some turbulence at times.

The upload interface has been revamped to take advantage of various fancy stuff that's been added to HTML and the underlying software stack over the last few years.

- The Create, Modify, Upload, Preview and Reorder pages have all been combined into a single management page, which also has several data readouts that were not previously available.

- Modern browsers can now upload an arbitrary number of files at a time, up to the gallery maximum of 2000. You can still upload archives, but it would no longer be necessary to create one just for the upload.

- There is now a progress indicator both for the sending and processing parts of an upload.

- Reordering can now both be done with the page selector and with drag-dropping the files around.

- Added the functionality to auto-reorder gallery pages based on the filename, using either a regular or natural sorting algorithm.

- You no longer need to explicitly "create" a gallery before you can start adding files to it, creation and initial upload can now be done as one action.

- Most of the "I have done something, click to continue" screens have been eliminated.

- Various layout tweaks to improve readability.

Please report any issues with the new uploader here.

After a month of internal testing followed by two months of public testing, we're sufficiently confident in the code's stability to end the 1.3 experimental branch and release 1.4.0 as a stable version.

This release incorporates all the changes from the 1.3 branch and fixes two minor issues in 1.3.3. While 1.2.6 will continue working for the foreseeable future, this is now the recommended client to use.


Fixes in 1.4.0

- Corrected a bug where malformed files in the cache directory would cause a NullPointerException and abnormal exit during cache cleanup.

- Re-added the User-Agent header to prevent leaking the Java version string.


Notes for upgrading from 1.2.x

H@H 1.4 requires Java SE 7 or later to run. This is a version bump from 1.2.6, which could run on Java SE 6.

The first startup with this client will take longer than normal, as it will have to reorganize the cache and delete the unused files that are not in the client's list of static ranges.

After updating, you can delete sqlite-jdbc-3.7.2.jar and the hathdl directory from the main directory, as well as hath.db + the log files from the data directory.


To update an existing client: shut it down, download Hentai@Home 1.4.0, extract the archive, copy the jar files over the existing ones, then restart the client.

The full source code for H@H is available and licensed under the GNU General Public License v3, and can be downloaded here. Building it from source only requires the free Java SE 7 JDK.

- Added persistence to the new cache handler, which means it no longer has to scan the cache on regular startups. The client will now start almost instantly regardless of cache size and CPU/storage performance, and go straight to the speed test.

A cache scan will now only be required if the shutdown was not clean, if the client had a reduction in the number of static ranges, or if a client that previously used --use-less-memory is started without using it. It can also be triggered manually with --rescan-cache

Note that the first startup after upgrading to 1.3.3 will always involve a cache scan, as the necessary data for fast startup is not saved by earlier clients.

- The static range age cache now tracks all static ranges instead of just the "aged" ones. This was necessary for long-term cache persistence, and because of the changes in 1.3.2 it will have no impact on performance.


Notes (READ BEFORE UPGRADING)

H@H 1.3 requires Java SE 7 or later to run. This is a version bump from 1.2.6, which could run on Java 6.

The 1.3 branch should be considered experimental/unstable and has a lot of new and rewritten code. If you are not comfortable with this, please stick with 1.2.6 for now.

1.3 and future versions of H@H will not support the Hentai@Home Proxy functionality. This option will eventually be removed from the site, and using it with a 1.3 client will not work.

The first startup with this client will take longer than normal, as it will have to reorganize the cache and delete the now unused files that are not in the client's list of static ranges.

Because of this reorg, it is not trivial to revert to H@H 1.2.6, as you would have to manually collapse the cache tree from two to one directory levels.

Note that while 1.3 explicity drops files that are outside its static ranges, they are no longer being used with previous versions either, so this does not actually affect the client's hitrate.

Startups past the first one will generally be faster than before, but as it involves a mandatory scan of the cache file structure, it could potentially take longer if you have particularly slow CPU and storage.

Barring any bugs, this release should be far more light-weight than 1.2.6, with reduced CPU usage, 1/4th to 1/2th of the RAM requirements, and a small fraction of the disk I/O for bookkeeping purposes.

After upgrading, you can delete sqlite-jdbc-3.7.2.jar and the hathdl directory from the main directory, as well as hath.db + the log files from the data directory.


To update an existing client: shut it down, download Hentai@Home 1.3.3, extract the archive, copy the jar files over the existing ones, then restart the client.

The full source code for H@H is available and licensed under the GNU General Public License v3, and can be downloaded here. Building it from source only requires the free Java SE 7 JDK.
