Subject [jira] [Commented] (COR-21) Extracting Externals Problems on Shared Drives
Date Sat, 10 Jan 2015 16:01:34 GMT

    [ https://issues.apache.org/jira/browse/COR-21?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14272564#comment-14272564

Dennis E. Hamilton commented on COR-21:
---------------------------------------

I don't understand this.  On initial extract to a new directory (T is created fresh for each
extract) the permissions should only be set after the files are created.

Generally, Zip extracts do not set unusual permissions.  It may be this is an artifact of
the zlib128-dll.zip containing Unix permission entries that are being handled in some abherent
way on Windows.

I suspect there is a bug and a race condition combining to cause this problem.  Note that
the same script code is used to extract all of the zips, not just zlib128-dll.zip and none
of the others have this problem. 

One key difference is that the zlib128-dll.zip does not have a single folder internal to the
zip as the others do.  So this could also be related to the different nesting.

I am going to dig into the zlib128-dll.zip a bit more and see what I can discover about this.

> Peter reported failures of the extract_downloads script when operating on a share from
within a Windows 7 VMware Guest.
> A similar problem has been replicated with a Windows 10 Guest on Hyper-V.
> It smells like some sort of race condition.  
> Some use on shared drives work, others fail.
