"/usr/bin/tar.exe" hangs, Windows 10, CYGWIN_NT-10.0 3.0.7(0.338/5/3) 2019-04-30 18:08 x86_64

[Keith Christian]

Tar in recent updates to Cygwin64 hangs.

When the tar command is run with strace, it generates voluminous
output but won't list tar file contents or extract the tar file (or
tar.gz, tar.xz, etc.)

Could someone check this please?

Works for me.  Could you have some anti-virus software that's interfering?  Look 
for suspicious DLLs in the strace output.

Ken, thanks for replying.

These are the DLL's in the strace output, expanded with "ldd."  I
don't see anything out of the ordinary.

Is there a list of DLL's known to cause problems with Cygwin?

How would I better isolate the problem causing DLL?  Specific verbiage
in the strace output?  Should I run strace with the "-a" option?

     1          CRYPTBASE.DLL =>
/cygdrive/c/WINDOWS/SYSTEM32/CRYPTBASE.DLL (0x7fff42b50000)

     4          RPCRT4.dll => /cygdrive/c/WINDOWS/System32/RPCRT4.dll
(0x7fff46070000)
     5          SYSFER.DLL => /cygdrive/c/WINDOWS/System32/SYSFER.DLL

     6          advapi32.dll =>

     9          cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x3ba9e0000)

I don't either.

Not that I know of.  But there is the BLODA list 
(https://cygwin.com/faq/faq.html#faq.using.bloda).  Have you checked that?

If you want to post the strace output somewhere or send it to me off-list, I'll 
see if I notice anything unusual.  Posting it somewhere is better, so that 
others can look also.

SYSFER.DLL is Broadcom/Symantec Endpoint Protection (SEP) AV/BLODA, which pulls
in all this other stuff, including MS VC RT, to clash with Cygwin, while
reporting back to corporate, hogging CPU and I/O to do so, slowing your system
to a crawl.

Uninstall it, bypass checking under the Cygwin tree, or don't use Cygwin.
If you feel a need for protection, Windows Defender is adequate; most AV
products are overkill, and kill system performance.

If this is in an org, complain (to your and their manager/VP) about the
interference stopping you doing your work, and make them fix it, so they
remember to do so in future, otherwise you may have problems and have to
complain and wait every time they upgrade.

Brian,

Thanks very much for the information.  I should have run "strings" on
all of the DLL's and then I would have seen that.
This is a corporate PC so little chance of doing any uninstalls or modification.
At least I know why now, and you've given me some ideas about troublesome DLL's.

Been there, done that.  Usually Symantec Endpoint Protection does come
with a support contract and Symantec support definitely knows about
Cygwin even when your IT folks don't.  So open ticket, support request
or whatever they call it with your IT and insist they escalate to
Symantec if they can't solve your problem (e.g. by excluding the Cygwin
install directory from heuristic checks).  The problem may return after
some updates or whenever someone feels that your company devices need
"extra" protection.  Sometimes it helps to do a full scan on the Cygwin
install directory, as some of the more problematic heuristics are
skipped when the scanner has seen and whitelisted a file before.


Regards,
Achim.

I've been "official" Cygwin app installer/maintainer at a couple of gigs, where
jumping thru the /virtual/ hoops to add Cygwin to the app catalog and assign it
to myself, was easier than asking or getting permission to install or use it.

Jumping thru the /virtual/ hoops to raise an issue can often prevent all future
issues: reference
