Null Images	ptdw [ Sun Nov 18, 2018 7:56 pm ]
I've noticed a lot of null images recently, often followed by the player mentioning something in the game thread about pics not showing after a successful upload. Any idea why an upload would return an image key, but subsequent access returns a null image? I guess I've always figured it was an issue with the player's connection, but it seems to be happening more often and people seem confident they've sent pics correctly.

Possibly a problem with the june changes correcting some picture upload. I'll need to get some more information (what fails, when..)

I've never seen it happen to me (that I know of), but the symptoms are: - player sends a normal jpeg via sendImage - sendImage returns a valid key after upload - receiveImage with the correct key returns a null string This has happened in Courtroom (especially), Spin the Bottle, Strip or Die, Human Paperboard (and likely others). Note that the image key is almost NEVER retrieved immediately, so there's likely some time that passes between when a player sends and when another player receives. This wouldn't be a security feature, would it? For example, accepting the image and immediately deleting if from a "bad" IP address...

Possibly a security feature, but not likely. I guess an error in some algorithms server side. If possible I'd like to know an example of image key that fails, from anybody.

It seems 37cfce64.jpeg is a good example. My scripts all do null checking, but in this case the file exists and is returned as 0 bytes, so the script continues and then runs into trouble. I checked this file on both Mac and PC and they both have the same issue. It would be great if the sexscripts server would return null in this case instead. Otherwise, we need to check all images for null, and then also check the byte length. Thanks for your help!

The file was not on the server. Most probably it was removed because without any access 14 days after its upload ; possibly something else. 3 updates : - This removal period is increased from 14 to 30 days - An error will occur (sendImage wll fail) if the file cannot be saved on the server - (sexScripts release from today) A good null value will be received if the image code has no matching on the server

This will make a big difference and should fix a lot of issues.

Hi @doti, We've been running into an image problem in Courtroom fairly regularly--it seems related to the null image thing. Players upload successfully, but when people go to view the evidence there's nothing there. Here are two recent examples: 5345293d and e1c1f573. Any insight you could provide from the server side would be really useful in debugging. Thanks!

Do you know how many time elapsed between upload and first download ?

Some cases in Courtroom have a longer evidence gathering time, so the images get uploaded and nobody views them for a few days, then they're needed for the trial. Perhaps that's related to the problem? Maybe when the evidence gathering time is short it works, and when long it runs into trouble?

If an image is never ever seen, it is deleted. I can check but I'll say 30 days later. But 72h means there's a bug. I've a hard time to investigate, I can see nothing in the (light) logs about those images. I'll add some more logs I think, I have no idea of the problem.

Hi doti, when test-playing HurrahForSchool the script showed me a null-image during the presentation of a punishment record. Digging into the code I noticed the script does a null-check before upload. So I guess this happened during upload or on the server. I wrote a short test-script to find null-images in the 20 images kept by HurrahForSchool and print out the image number and the upload-date of the image stored in the school-record (a string on the server). Here's the list Code: Image Date 846ddc81.jpeg 26/5/2019 8dc4a428.jpeg 26/5/2019 df00d144.jpeg 27/5/2019 437f6005.jpeg 27/5/2019 88060666.jpeg 27/5/2019 38dd04ba.jpeg 25/5/2019 9be1a169.jpeg 26/5/2019 01b387db.jpeg 27/5/2019 0ede6747.jpeg 27/5/2019 c28ed515.jpeg 27/5/2019 fdafb204.jpeg 22/5/2019 From this I dare to deduce The problem is not specific to courtroom. The problem occurs more often than we might have guessed. The deletion-time on the server is not the reason. Hope this helps to find the cause of the problem. From what I saw it started to occur after a certain update of sexscripts. I just don't remember the last working version. Regards cgut2001

I wrote a short test-script to find null-images in the 20 images kept by HurrahForSchool and print out the image number and the upload-date of the image stored in the school-record (a string on the server).

Here's the list

Code:

Ok, with those informations I found a bug on the server that was deleting some big files uploaded the day before. Corrected.
