"ERROR: Cannot create folder" on some archives #25

Open pxdl opened 8 months ago

pxdl commented 8 months ago

While trying to extract some archives in the browser environment with the

sevenZip.callMain(["x", archiveName, "-oextracted"]);

command, 7zip will simply show the following errors:

ERROR: Cannot create folder
ERROR: Cannot open output file : errno=2 : Permission denied

This only seems to happen with some archive files.

Testing with

sevenZip.callMain(["t", archiveName]);

before extraction returns an Everything is Ok message from 7zip.

Setting permissions with

sevenZip.FS.chmod(archiveName, 0o777);
sevenZip.FS.chmod("/extracted", 0o777);

also seems to have no effect either.

Here are some examples of archives that can be extracted: https://github.com/CTCaer/hekate/releases/download/v6.0.7/hekate_ctcaer_6.0.7_Nyx_1.5.6.zip https://github.com/Atmosphere-NX/Atmosphere/releases/download/1.6.2/atmosphere-1.6.2-master-f7bf379cf%2Bhbl-2.4.4%2Bhbmenu-3.6.0.zip

Here are some exapmles of archives that cannot be extracted: https://github.com/HamletDuFromage/aio-switch-updater/releases/download/2.23.2/aio-switch-updater.zip https://github.com/ndeadly/MissionControl/releases/download/v0.10.0/MissionControl-0.10.0-master-38c9879.zip

What could be possibly causing these issues? Are these archives being created differently?
