Another setup v2.889 regression?

Another setup v2.889 regression?

Hi,

Because there are problems with setup v2.889, I decided to do
some testing of my own.

I started out with empty directories for the repo (a.k.a. the
Local Directory?) and the root directory ...

After having downloaded and installed the "required" packages,
I again started setup (3rd time and 4th time) to download and
install "cscope" (yes, one of the packages).

Then I started setup for the 5th time (download): it reported
"nothing to install".

When I started setup for the 6th time (install), it wanted to
replace cscope (v15.8b-1)  with an older version (15.8.0.1-2)

 From /var/log/setup.log:

  cscope             15.8b-1

 From override.hint on the "Twente" mirror:

curr: 15.8b-1
prev: 15.8.0.1-2
replace-versions: 15.8.0.1-2

As far as understand, setup should attempt to install v15.8b1
in case v15.8.0.1-2 is installed.

Not the other way around. (currently v15.8b-1 in installed).

Sorry, I should have added ...

I always invoke setup using a shortcut, i.e. the invocation is
always parameterized as follows:

     E:\_cygwin64_repository-test\setup-x86_64-2889.exe \
     -n -R e:/Cygwin64-test -l e:/_cygwin64_repository-test

(startup-directory: e:/_cygwin64_repository-test)

Version epochs need to be used to resolve version format changes.
They are now supported in most of the packaging utilities, but once they are
used in setup.ini and installed.db, all older packaging utility versions will
break.
How soon would you like that sir? ;^>
It's damned if you do, and damned if you don't: substitute your own localized
translation.

Another setup v2.889 regression? Again ...

Sigh.

I repeated the whole process and this time setup wants to download
v15.8.0.1-2 (i.e. the older version which it should not download).

Being surprised, I went backwards (GUI) and forward again, and after
that setup had again changed its mind (again "nothing to install").

Aborting setup and starting setup anew, it again wants to download
the previous version of cscope ... which I declined.

Btw, if setup is started in "install mode" after the above, it wants
to install the previous version of cscope (which it is not there).

Continuing the install results in UNstalling cscope (v15.8b-1).

Hey, I think something is up with your mail client. I see you are using
"XS4ALL Webmail" (not sure what that is). First you put a new thread here:

  http://cygwin.com/ml/cygwin/2018-03/msg00038.html

Then you replied to yourself here:

  http://cygwin.com/ml/cygwin/2018-03/msg00042.html

but your mail client is not prepending the subject with "Re: ", so it appears
you started a 2nd thread. Then you replied to your original post again:

  http://cygwin.com/ml/cygwin/2018-03/msg00047.html

and again no "Re: ". Whats even more maddening is that not only do your replies
not have the "Re: ", but they dont even have the same subject:

- Another setup v2.889 regression?

hey troll, get back under the bridge.

on the contrary, your client is messed too. if you looks here [1], you will
notice that your client is incorrectly inserting UTF-8 replacement characters,
while my original message [3] has no such characters. perhaps your client cannot
handle UTF-8?

You appeared to be unfamiliar with a long time well known global ISP, and the
commonly used term webmail. Most posters on this group try to be helpful to
others in this international forum, where many posters native language is not
English, although that may not be obvious, use Cygwin as a tool do do their job,
and may be unfamiliar with common conventions.

Changing subjects is merely a question of style, and as with other preferences
like editors, languages, cultures, etc., and beliefs like religion and politics,
should be reserved for forums where that is on topic, and if disagreed with,
done so with due consideration, without being disagreeable.

The troll is the person who disrupts the on topic technical problem discussion
with minor off topic nitpicks about clarifying additions to subjects, and those
changes causing issues with *their* mail client, that is not apparent to anyone

As I use a mail client, those characters are actually spaces in the raw
messages, however for rendering as HTML on Cygwin.com/sourceware.org web mailing
lists, for horizontal spacing the site uses standard Unicode \u00a0 ' ' no-break
space utf-8 \xc2 \xa0 character entity rendered as a space, but "raw text" does
not appear to be the original message content, but appears to convert the HTML
content to utf-8 regardless of the message encoding charset, resulting in
Unicode \ufffd '�' replacement character utf-8 \xef \xbf \xbd.

I have been using utf-8 character encodings for years to handle information from
my own and other cultures more transparently, replaced components which do not
support it with alternatives which do, and been annoyed at how long it has taken
to get only this far, pushing against those struggling to retain their small
proprietary markets rather than contest an open global market.

Please use sane mail client that understands References/In-Reply-To message headers.
Subject linking was frowned upon twenty years ago already.
How could you use it in 21'st century is beyond me.

Yeah, this isn't working as expected. Time for a bigger hammer...

The previous version has been re-designated as 15.8a-2 (to match what it 
identifies itself as with 'cscope -V').

This should make setup update to the most recent version, while still 
allowing the previous version to be offered as installable...

Uhm, bigger hammer ... you mean your modification will solve the problem
for cscope, but not for f.i. the *lz4* packages?

Sigh.  I thought I had fixed lz4 [1], but apparently not, it suffers 
from the same class of problem (briefly, replace-versions: doesn't work 
on versions which are also offered for installation)

These are the only other packages which I am aware of which suffer from 
this specific problem, and I'm not sure I want to fix those in the same way.

If you think there are other package which have this problem can you 
please tell me what they are...

As far as I _understand_ the issue, the *lz4* packages are the only ones left,
which present the same problem as cscope does

I glanced over setup.ini and compared the packages with "replace-version:" with
the entry for cscope ... Only the *lz4* packages stood out within that context.
