Enabling PAR2 creation causes upload failure

[kraft-sodass]

Hello,

first of all I want to say how much I appreciate the work you are putting into this very fine upload client.
I have been playing with it for the past few days and unfortunately, I cannot get PAR2 creation to properly work.

System information
I am using Postie CLI version 0.0.29 on Windows 11 with the three required MingW64-DLLs (libgcc_s_seh-1.dll, libstdc++-6.dll, libwinpthread-1.dll in version 15.2.0) placed besides the EXE, as the current release can't launch without them.
I call Postie like so:
postie -c config.yaml -d "some directory"

I am testing with two files in a folder with a total size of 96 MB.

PAR2 creation via internal Par2Go
This gives an error message and does not create Pars at all.
The error is: par2go: SliceSize must be a positive multiple of 4, got 361254
Changing the 'SliceSize' setting in the config.yaml does not change the error at all, it always says '361254'. I have tried with the default '0' as well as some custom values, no change.

PAR2 creation via ParPar
This starts off nicely, creates all the Pars and then the upload becomes stalled between 96 % and 98 %. Postie will then hang until it has reached the maximum number of retries and then exit with this error message:
Error: failed to post file XXX after 3 retries: error posting article: nntp: post failed: news.XXX.XX:563+XXX: read tcp XXX.XXX.XXX.XX:51376->XXX.XXX.XX.XX:563: i/o timeout

I have tried with the same files multiple times and can always produce the same result:

• PAR2 disabled =Upload fine.
• PAR2 enabled = Upload hangs and ends with the above error message.

I have found that when I increase the setting 'min_connections', the upload will hang sooner. For example, with 'min_connections' at 1, it will hang at 98 %. With 'min_connections' at 3, it will hang at 96 %. Changing any of the other settings did not make a difference.

Can you try Last dev build https://github.com/javi11/postie/actions/runs/24284805491 all the issues shouldbe fixed

I have tested.

✅ PAR2Go now works, no more SliceSize error message

❌ Postie still cannot launch without the three DLL's, as mentioned above

❌ Upload will now always hang at 96 % - 98 % and never complete
I now get the i/o timeout error message from above everytime, no matter whether PAR2 is enabled or not. As I wrote above, with release version 0.0.29, the error only occurs when PAR is enabled. With dev version, error occurs everytime.

I have also noticed that Postie does not output an NZB in case of an error, which I think is not clever for an upload that failed at 98 % and would therefore be easily repairable. Without the NZB, the upload is gone forever. Perhaps you could consider changing this behaviour so NZB is always written, regardless of error?

I have also noticed... hanging this behaviour so NZB is always written, regardless of error?

In any case, this behavior should be optional if it gets implemented. Personally, i really don’t want to create partial .nzb files even if they could hypothetically be repaired later.

Any updates on this?

I will check as soon as possible, its difficult to check it on windows, lets see if i can add some github test for that
