334.0. "/EXCLUDE qualifier on $ UNSHELVE - Wrong interpretion or bug?" by BRSSWS::VERCAMMEN (You never walk alone...) Tue Apr 15 1997 05:06

	Hi,


	I wanted to UNSHELVE all shelved files on a certain disk EXCEPT 
	the files with extension .CPD.

	Therefore I used the command :

EPLZ02 > unshelve/exclude=*.cpd/log/nowait $1$dua141:[000000...]*.*.*

	but it still unshelves *.CPD files, as shown by the following 
	output: 

%UNSHELVE-S-QUEUED, file $1$DUA141:[PSDC]EPLZ00_VPA.DAT;5 queued for unshelving
%UNSHELVE-S-QUEUED, file $1$DUA141:[PSDC]EPLZ00_VPA.NEW;1 queued for unshelving

	Am I interpreting the /EXCLUDE doc wrong or is there some hidden
	'feature' that shows up?


	Thanks and regards,

    Hi! 
    
    This problem doesn't seem to be reproducable:
    (at least at VMS V6.2, HSM V2.1 (BL24) )
    
    VNA03$dir b*.* /shelv
    
    Directory DSA2:[MICHAEL_KARTNER]
    
    BACKUP.TEST;2        Shelved
    BOOK.COM;1           Online
    
    VNA03$unshelve/exclude=b*.* /log/nowait DSA2:[000000...]*.*.*
    %UNSHELVE-W-NOFILES, no files found
    
    What versions are you running ?
    
    								bye
    								Michael

	Michael,


	It is reproducable at will when specifying the EXCLUDE
	file specification as *.file-extension (ex *.CPD).

	We are also running OpenVMS VAX V6.2 and HSM V2.1 (BL24).

	Might be a problem in the command parsing...


	Regards,

	\Jan 

    Hi!
    
    Next test!
    
    Directory DISK$USER02:[MICHAEL_KARTNER]
    
    BACKUP.TEST;2        Shelved
    BOOK.COM;1           Online
    
    unshelve/exclude=*.test /log/nowait *.*;*
    %UNSHELVE-W-NOFILES, no files found
    
    								bye
    								Michael
    

Hello Jan & Michael. 

It appears Jan has uncovered a bug in the /EXCLUDE qualifier processing. 
The problem is that the excluded filespecs are initially sys$parse'd and 
acquire the user's current directory spec. Later, the parsed spec is compared 
against each shelve candidate filespec, when the directory portion may have 
changed. 

This explains both Jan's observations in .0 and Michael's observations in .1. 
I have QAR'd this and it will be fixed in the next release. In the interim, I 
guess you will have to explicitly specify the directory(ies) with the exclude 
qualifier, or set the files /NOSHELVE first. 

Thanks to you both.
