Wget + bsdsocket emu = crash

[hexaae]

No problem using MiamiDX + uaenet.device, but running Wget (any version from Aminet, up to 1.11.4) from shell in bsdsocket.library emulation causes memory errors and crashes from Workbench (any version I guess).

Try "Wget -h" multiple times from shell...

Sounds like the usual with unix ported programs: huge stack needed.

No. In MiamiDX+uaenet it works fine even with 16KB of stack.
Already tried with stack 500000 but always trashes Amiga mem in bsdsocket mode instead. This should be reproducible. I can make a log with JIT OFF if you need though… just tell me the paramater at launch for the log to monitor networking

Can't duplicate. (as I expected because I have used wget previously)

Possibly ixemul.library related (as usual..) EDIT: Keep backup of the library and upload it if using other version fixes it.

My ix### libraries attached: https://gofile.io/?c=2qfaot

Still crashes using other ix libs from Aminet… and only in bsdsocket emu mode. Never in MiamiDX+uaenet. At this point it must be system specific...
Is there a special parameter I can use to generate a helpful logfile?

Not a solution for your problem, but an alternative could be aget that you can get here or from aminet.

Thanks, will have a look.

@Toni
Could it be a problem with MMULib <-> ixemul, when using Wget with bsdsocket emulation?
From a boot without SSeq I tried Wget and a pop-up requester for a "68640.library emulation code not found" appeared… Then I run Setpatch 44.38 (using OS3.9 + MMULib to handle various CPU/FPU the easy way) and the crash/recoverable appears at every Wget run (in bsdsocket mode only!!?)…

Attached my mulibs (decompress it in LIBS: ) : https://gofile.io/?c=LMuL0n

EDIT: redownload please

It appears to be bug in wget. It closes bsdsocket library twice (at least when executing --help) and because bsdsocket library is per-task library, library goes away when closed (and opencount is zero), next invalid close call may use corrupt memory.

Crash also depends on how socket library internally works.

Since I doubt quick Amiga68k ports on Aminet will ever try to fix that... could be added a workaround in bsdsocket emu for this specific case?

As far as I can understand this could affect also real Amiga systems, right?

[Toni Wilen]

Finding matching sources would help because for some reason it still crash somewhere else even if I force library close to do nothing.

I've sent a mail to the author of the last port on Aminet:
http://m68k.aminet.net/package/dev/gg/wget-1.11.4-bin

I've found this in the meanwhile:
https://github.com/diegocr/wget-amiga

[Toni Wilen]

main.c looks ok, it closes library(if open) when program exits. So I'll blame ixemul.library again

[hexaae]

This one works fine with bsdsocket emu https://sourceforge.net/projects/ami...2.lha/download !
Moreover is even more recent than Aminet or GitHub versions: v1.12

[Toni Wilen]

It also does not use or require ixemul.library.
