.pkg download cache issue - taking space even if removed

Tea-pot commented 9 months ago

First of all thank you for this port, appreciated! Issue:

while package downloaded but filed to install / failed for other reason, it shows 0kb in ms0:/PKG

_Where to remove interrupted/failed downloads to free up disk space?

Check the ms0:/PKG/ folder - each download will be in a separate .pkg file by its content ID. Simply delete the file and start again._

mentioned solution does not work. Space is taken and have not been restored. tested with EP9000-NPEG00007_00-GNAMCOMUS2GO0002 PSP model 1004 modded, 6.61 PRO C2 + infinity 2.0.3

I have also deleted PKG and all files using PSP Filer - space has not been restored. Do you happen to know where the cache folder is, or how the download of .pkg is handled?

bucanero commented 9 months ago

downloads are only stored in ms0:/PKG. But maybe you have a broken install folder taking space?

if installed as Digital, you should check for /PSP/GAME/title-id , you might find a folder there.
if installed as ISO/CSO, check under /ISO

keep in mind, you need 2X space to install, if you have a 100 Mb package, you need at least 200Mb free. (100 to download, + 100 to install)

Thank you. I understand it much better now. I could not finda any broken/corrupted files unfortunately in any of those locations, I have already removed PKG folder and all content. I made some space now and I will test this again - the same game, the same source PKGi to ms0:/PKG i will keep you posted.

Some findings: I have freed up 1400mb ( in total I should have almost 1900mb since I have lost 542mb once downloading EP9000-NPEG00007_00-GNAMCOMUS2GO0002 - ending up with power outage - battery died console was not plugged in file in PKG was 0kb in size ), I have performed the same test - attempting to download file, console was not plugged in - died, I have lost 200mb - non recoverable - no trace of file / cache. I have attempted the same once again - successfully downloaded and installed EP9000-NPEG00007_00-GNAMCOMUS2GO0002 - works as intended - total space left 732mb.

4gb aftermarket Memory Stick Duo - some small files, i ISO 1.35Gb, one converted PSX game 494Mb SLUS01066, and successfully installed EP9000-NPEG00007_00-GNAMCOMUS2GO0002 as NPEG00007 542Mb
2386Mb this is how much space installed games takes. Including + 732Mb space that has left on MSDuo 3118Mb I have lost once 542Mb - first failure of downloading/installing EP9000-NPEG00007_00-GNAMCOMUS2GO0002, and around 200Mb trying the same again - not recovered so far, in total this would gave us 3872Mb - feels more like capacity of 4Gb MSDuo
performing test I have lost around 754Mb without trace. Therefore I am wondering how the data is managed, where to find 'cache' of failed operation? This would be interesting to know. Would be also good to know how those situation would look while accessing the retail PSN shop, how those issues would be handled by Sony.

Well, if your PSP shut down while downloading as it ran out of power, then it's not an issue with the app. It's a file system integrity issue. Probably the .pkg file descriptor was open, then the battery went out, and the FAT table was never updated properly with the downloaded data. So, blocks are marked as used, but the file system ends up in an inconsistent state.

My suggestion, you have two options: try a scandisk tool, and see if Windows can detect and fix the FAT32 file system, or the other option is to backup everything, then format and restore data.

As a side note, I'm adding a battery indicator so users know the current batt level #11

Thank you. I do not blame app itself, I blame myself definitely for messing with power, just wanted to check how this will be handled. Thank you for suggestions. As there is no issue with app - 'cache' issue or mess with FAT table is another sort of issue that has nothing to do with app, this can be closed. It was more on a site of curiosity and for the others to be aware of.

Thank you for battery indicator, this will be handy.

Thank you for battery indicator, this will be handy.

if you want, feel free to test the latest build with the battery display: https://github.com/bucanero/pkgi-psp/actions/runs/6553994915

just go there and download the "Artifact" link, then you can install and test it.

btw, this build also has an updated "free space check", it will block downloads if you don't have 2X the .pkg size free.
