setup.exe 2.194.2.24 "Download from Internet" misbehaviour

[Nikolaus Schmitt]

[-- Attachment #1: Type: text/plain, Size: 830 bytes --]

Using setup.exe v2.194.2.24 to download cygwin modules from the internet,
the following happens:

Settings:
- Local package directory = N:\upload\cygwin (networked drive)
- Connection type: direct
- Download site: ftp://gd.tuwien.ac.at
Choosing another download site, the directory mentioned in step 4 below
happens to change to the encoded URL accordingly.

1. Starts download setup.ini
- setup-timestamp: 1018906576
- setup-version: 2.194.2.24

2. Shows up module selection dialog
- O.K.
3. starts downloading selected modules
- O.K.
4. CREATES DIRECTORY "ftp%3a%2f%2fgd.tuwien.ac.at%2fgnu%2fcygwin"
- This seems not to be the programmers intention?
5. creates subdirectory "release", containing the module subdirs
- seems to be O.K.

Q: Is the creation of a site dependent subdirectory holding the modules
intended by design?

An deeper and not before asked question about setup.exe

[Max Bowsher]

First, I've read this thread, and others:
> Yes, it is! :) This topic was covered multiple times on the mailing

In it, it says: This is done to allow fetching from multiple mirrors.

My question is this: _Why_ is it necessary to create mirror-named directories to
allow the downloading from multiple mirrors?
I have no doubt it was done for a reason, but I would very much like to know
that reason.


Thanks,

Max Bowsher.

Please don't take this the wrong way but why do you care?  Is there a problem
with the implementation that makes it not work for you?  If so, please be 
specific about your problems and feel free to submit patches which fix it and
help us understand your issue.

If you're interested in discussing the design of setup in this area, you 
should review the email list archives.  This particular issue has been 
discussed at least in passing.   But I'd venture a guess that unless the 
current implementation is buggy and can't be fixed with reasonable effort,
not allot of redesign will go on into this area.  But perhaps I'm getting 
ahead of your intentions.  Maybe it's best that you state them.

I searched, but did not find.

No, that's ok. Here is why:

I need to maintain my local package directory to remove old versions. Having the
packages scattered between mirror directories is unhelpful. Therefore, I use a
modified version of the clean_setup.pl that was posted here a while ago. I do
not understand, and could not find in the archives, a reason for using these
directories at all. If there is a reason, then sorry for the list noise, if not,
I would suggest the folder layout be reconsidered.

Thanks,
Max.

OK, I understand why you're asking what you're asking.  Here are the
salient points that help answer your question (from memory based on previous
list discussions on this subject):

   1. The current structure supports multiple site downloads with 1 invocation
      of setup.  This helps mitigate mirror site latency problems when updated
      or new packages are released.

   2. The actual naming of the new download directory is standard's based, 
      though I don't remember the specifics here.  It's not clear that you
      have any objection to this naming but I thought I'd mention it since
      it seems pertinent.

   3. The form of setup's download directory is not and won't remain static.
      It will change as setup's needs change.  If you plan to try to maintain
      the download directory with some external script of your own choosing,
      you will need to maintain that script through these changes.   

In summary, there are no plans to make the download directory a static form.
And although there has been some discussion about collapsing the multiple
directories into one, there's no guarantee that this structure will match 
that which you are used to, even if it does happen.  

HTH,

There's a newer version of clean_setup.pl at
http://home.ix.netcom.com/~mchase/zip/ that deals with the new directory
structure.  It will also, optionally, flatten it for you.

Thanks, it's a very useful tool, but version 1.02 already does everything I
need. (But I did have to remove lc, which was lowercasing the word STABLE in
squid versions, and so causing clean_setup.pl to complain that it could not find
squid...stable..., and that squid...STABLE... was not in setup.ini)

I'm really gently suggesting that we shouldn't need to have a script to merge
the mirror directories, because (as I understand it) they serve no purpose.

Thanks.  I'd put the lc() in to deal with Windows' case insensitive
filesystem and didn't catch it when I removed the workaround from other
parts of the program.

Version 1.03 will properly find archive files even when the parent directory
names change.  This is particularly relevant now with the migration from
contrib/ and latest/ to release/ .

The separate mirror directories are intended to support future
functionality.  For now the only part that is really useful is that they
provide a place for a separate setup.ini for each download site.

If someone is trying to manage a cache on a network drive for installing
Cygwin in multiple machines, the merging may still help.
