Activity for ethflop
-
Mateusz Viste committed [r226] on Code
updated links
-
DOS client archive does not need to mention DOS
-
ethflop released /ethflop (client)/20240920/ethflop-20240920-src.zip
-
-
-
frozen ver 20240920
-
release.sh flagged as executable
-
added a convenience bash script to package releases of ethflop
-
versioning scheme changed from x.x.x to YYYYMMDD
-
stack overflow detection does not rely on any specific signature
-
messages are properly CR/LF terminated
-
updated download links
-
-
frozen ver 20240916
-
-
version bump
-
improved wording
-
minor help screen changes
-
frame buffer space is used by transient program to store part of the help screen not to waste a disk cluster
-
new convenience function to print AX on screen
-
reordered routines to gain a few short jumps
-
moved functions and strings to separate files
-
moved all transient functions to the end of the file to keep routines on top and hence favor short jumps to them whenever possible
-
made some labels .local + explicited a few jumps as short
-
explicitely flagged all jumps in the TSR as short jumps so nasm is never tempted to assemble them in a long form behind my back
-
improved wording
-
maximum stack usage during TSR lifetime can be consulted under "ETHFLOP !"
-
moved frame buffer at the bottom of the stack so it takes the hit in case of a stack overflow event
-
2 extra bytes for stack reservation are not needed because PUSH first decrements SP and then writes values, not the other way around
-
configurable stack space
-
improved help screen
-
improvement a few comments
-
build.bat switched to proper cr/lf line endings
-
transient code checks the health of TSR's stack (stack overflow detection)
-
version bump
-
constified argument ptr in debug routine
-
UDP query to list images wrap lines every 8 images
-
UDP commands to insert and eject a floppy return errmsg only if truly an error occurred
-
implemented insert action in UDP API
-
implemented API (UDP) action eject ("e")
-
implementation of client list and image list in UDP API
-
reset sectcount and readonly flag in client struct when floppy is ejected (not really needed, but hygienic)
-
doc update + version bump
-
added -c mode help
-
client mode (ethflopd -c) to query and control the daemon
-
prototype with a unix socket control channel (does not work)
-
remove failed images + improved error message
-
using open() instead of fopen() to avoid overhead as much as possible + preallocating content of all standard-sized floppy images at creation time (floppies <= 2880K)
-
extra check to detect malformed think-provisioned disks
-
hide driveid when ethflop does not provide the correct one (older ethflop TSR)
-
floppy images are created thin-provisionned
-

-
doc update
-
version and copyr dates are stored in a common header file
-
DOS version: take care to zero out the root entries of newly initialized floppies
-
logging the time it takes to generate a new floppy image
-
improved changelog
-
fixed the earlier enospc fix
-
failed image is removed
-
fixed "out of disk" situations on the DOS version
-
mark the floppies list as empty when no images found, so the UI knows image-selecting mode is forbidden
-
improved validation of answer frames (ECM)
-
updated mdr
-
quit early when pktdrv not found (UI is not inited yet)
-
fixed message about packet driver int found
-
removed reference to non existing pktdrv.c
-
newest ethflop provides the client driveid in each data frame so server message can be more informative
-
ethflop signals the TSR's drive letter to the server (nicer messages)
-
TSR closes all its handles to avoid potential SFT leaks (thx ECM)
-
when hooking drive B: ethflop checks first if it is not a phantom drive
-
updated links to newer release

-
mounting a floppy with write access is forbidden if anyone uses it already
-
careful about segment overflow when scanning int 0x60..0x80 for a packet driver (spotted by ECM)
-
setting size of operands on memory side for better clarity
-
improved comments + setting size of operands on memory side for better clarity
-
env seg is zeroed in PSP before going TSR (just in case)
-
size definition should be on memory side for better clarity (idiomatic convention, suggested by ECM)
-
cosmetic fix for refreshing entries in the img list
-
implemented cached answers in Linux version
-
implemented caching of answers
-
updated mdr
-
added /hlt and /noui

-
renamed tag so it reflects ethflop version
-

Linux Makefile uses gcc

improved timeout and retransmission routines: first retry after ca. 250ms, then every 440ms and timeout after 2s
