Hi Eric, 2009/6/5 Eric Auer <e.a...@jpberlin.de>:
> Bart seems to work on this a lot, but unfortunately there is > nothing about the progress on the mailing list. well, at the time of setting up SVN I asked Jim if he could set up sourceforge so the patches to go to the existing freedos-cvs mailing list (where CVS commits were sent), put he seemed to not understand what I meant. Anyone with admin rights, Aitor? Jim? Pat? you can do this on SF: click "Project Admin" click "Feature Settings" click "manage" next to "Subversion" add an svnnotify hook, and type freedos-...@lists.sourceforge.net as the email address. the main ideas of the changes: * there are only two near fnodes, and almost all operations use the first fnode, fnode[0] except for dos_rename(), which also uses fnode[1]. * file state is only kept in SFTs: an open/creat uses fnode[0], then copies the state to an SFT a read/write copies state from the SFT to fnode[0], does its work on fnode[0], then copies back to the SFT. a close copies from the SFT to fnode[0], and closes the file. * For FAT16 kernels, the SFT layout is documented in RBIL * For FAT32 kernels, the SFT layout follows that of MSDOS 7.10 (not documented in RBIL). * the share support also needed some changes, because it needs to walk the SFTs instead of the far fnodes to merge changes. > Otherwise I > would ask why r1416 rmdir drops the 00/eof check (does it?) > and why r1397 drops the dos_commit-only way of close(?) and > how get_f_nodes_cnt works, among other things... well, you ask these questions anyway, one wise or otherwise... r1416: Look at what dir_read(fnp)==1 means in fatdir.c... r1397: dos_commit was no longer necessary: a commit (int21/ah=68,6a), in DosCloseSft() just calls dos_close() without closing the SFT. get_f_nodes_cnt() was an intermediate function that no longer exists (to keep individual changes small) It just walked the SFT chain and computed the FILES= value.
