Hi All, A few days ago, Willi discovered an odd File Name related bug.
When installing the ADT2 package[1] from the repository at FD.LOD.BZ using FDNPKG, it would install the 999 files in the package. However, the FREEDOS\PACKAGES\ADT2.LST file would only contain about 300 entries. Uninstalling the package would obviously leave many files behind. There may have also been some file system corruption during the install. The issue did not occur under DOSBox Staging with FreeDOS installed in "Hybrid mode". The "Hybrid mode" install under DOSBox(s) is mostly the same as a that for a virtual machines or real hardware with one major exception. The "Hybrid mode" install does not use the FreeDOS kernel. It uses the DOSBox kernel. This permits the easy exchange of files to and from the host system. Other things, like FreeCOM and drivers from FreeDOS are used in the install. This type of install is extremely useful as a development environment for many types of DOS programs. I then tested this under VirtualBox and could replicate the issue he found easily. However, the problem installing ADT2 did not occur when DOSLFN was not loaded. But wait, there is more… Willi also tested a few other packages and discovered a similar issue with Arachne[2]. But in this case, the presence of DOSLFN did not matter. But, installing via FDNPKG or FDINST made the difference. In regards to both packages, there are a couple odd characters in some file names. One contains an ampersand and the other exclamation points. According to a wiki on 8.3 file names[3], these are permissible without LFN support. At this time it is unclear where the bug is located. It could reside in the KERNEL, DOSLFN, FDNPKG or elsewhere. The new FDRepo v3 can pull files directly from GitLab and generate packages for download/update repositories. When it does that, it scans for and pre-compresses LFN files using an algorithm based on that wiki page[3]. I could easily make it more restrictive than what is permitted in 8.3 file names. However, that would not fix the actual problem and could have other side effects when installing packages.
