Error on Windows: "system cannot find the path specified. (os error 3)" #8

Open asclepiadae opened 2 months ago

asclepiadae commented 2 months ago

Downloaded the Windows compiled binary, and tried running it. The binary is located in the folder that I am looking to download the Moodle data to. The path is nice and short: C:\Users\usern\Moodle

I am using the following in PowerShell and CMD as the first part of the full command as I have a token: .\edu-sync-cli add https://moodle.domain.tld path

I have tried the following as the entry for the path:

\
/
~
~\
.
C:\Users\usern\Moodle
C:/Users/usern/Moodle
"C:\Users\usern\Moodle"
'C:\Users\usern\Moodle'
download
\download
C:\Users\usern\Moodle\download
C:\Moodle\
C:\Moodle

Note that the folders C:\Users\usern\Moodle\download and C:\Moodle do not actually exist, just in case the utility needed a path to create a directory.

For every single attempt I get: Error: The system cannot find the path specified. (os error 3)

If I run .\edu-sync-cli config I get a very nice returned line: C:\Users\usern\AppData\Roaming\Edu Sync\Edu Sync\config\Edu Sync\Edu Sync.toml

I just don't understand why that format doesn't seem to be a valid entry for the download-to path!

AH! Progress has been made...

So it seems like the issue is actually with the config path! Running .\edu-sync-cli config returned C:\Users\usern\AppData\Roaming\Edu Sync\Edu Sync\config\Edu Sync\Edu Sync.toml but that full tree and file did not exist. The directory tree did exist up to this point: C:\Users\usern\AppData\Roaming\Edu Sync\Edu Sync\config

Creating the final \Edu Sync\ directory and then leaving it empty to allow the Edu Sync.toml file to be created solved the issue and accepted a normal Windows directory path!

Aaaaand part three... I think I have narrowed down the issue, and it's affecting more than just the initial run but the actual sync process.

I believe it has to do with the limitations Windows has on path lengths, which is apparently still a problem...

After the sync completes and gets most files, there are 182 items that are left unsynced. The tasks panic and produce toml report files like the following:

I haven't done a full comparison of the many many report files, but it does look like it's some sort of crash due to Windows path issues. Yaaaaaay.
