Understanding versions of apps in cygwin suite

Understanding versions of apps in cygwin suite

[Andrew Hancock]

According to http://savannah.gnu.org/bugs/?func=detailitem&item_id=30309 , a bug
with octave's wavread function was fixed in octave 3.2.3.  My "cygcheck -cvs"
shows an octave of 3.4.2, but I still get the bug.  I was wondering if it is
wise to assume that the app version number from cygcheck is the same as the
version number from the gnu site?

Hi Andrew

in general the cygwin packages are aligned with upstream versions,
eventually with additional patches.
Octave package 3.4.2-3 is aligned with upstream 3.4.2.
http://cygwin.com/ml/cygwin-announce/2011-10/msg00001.html

I guess you have some problem on your octave package,
and you can also check the version with:

$ /usr/bin/octave --version
GNU Octave, version 3.4.2

and on my system:

octave:2> Y = wavread("oddchunk.wav")

is working fine as expected.
If you have problem with a different example file, than
please rise the problem on octave bug system or send me by
private mail your file, and I will check against the development
build.

If your version is not 3.4.2-3, close all cygwin programs
and re-install octave.

Regards
Marco

Thanks, Marco.  I posted on another thread asking whether it was wise to update
Octave without updating the cygwin DLL.  Updating the cygwin DLL using Setup is
actually downgrading, since I currently use a snapshot of the cygwin DLL to get
around a problem with creating files/folders on a network drive (unrelated to
Octave).

Since I am unclear about the interactions between the packages and the cygwin
DLL, I have been trying to avoid updates to cygwin and packages until a new
release.  However, I will do it if all other ways of poking and prodding a
problem are exhausted.  One of the poking/prodding I want to do is check octave
release notes.  I haven't been able to find an archive of release notes for
various octave versions and subversions, but I did find the savannah bug
tracking system.  It doesn't help determine the incremental changes from version
3.4.2-1 (what I have) and 3.4.2-3.  Finding your postings on the cygwin mailing
list archive indicates that the changes are not related to wavread, but as you
say, it might be my particular circumstance -- especially since the bug was
apparently fixed in 3.2.3.

I'll take you up on your offer to email you the file.  It is a 23KB file that is
a truncation of drum beat track 428 available at
http://www.instructables.com/id/Drum-Beats-in-Audacity.  Thanks.

Andrew,
cygwin setup is not aware of any snapshot you can install manually,
as it compares the info from setup.ini (from website) with
the info stored on its database /etc/setup/installed.db

So if you have

$ cygcheck -c cygwin
Cygwin Package Information
Package              Version        Status
cygwin               1.7.9-1        OK

as 1.7.9-1 is the last released version, running setup again
to upgrade octave, will not replace your snapshot.

I am also running a snapshot as 1.7.9

$ uname -rv
1.7.10s(0.255/5/3) 20111129 17:41:48

for the reason reported on
http://cygwin.com/ml/cygwin-announce/2011-10/msg00001.html

It seems a different problem of the bug you thought about,
both the 3.4.2-3 and the latest development build do not recognize
the file format.

octave:2> Y = wavread("428shortMono.wav")
error: wavread: file contains no RIFF chunk
error: called from:
error:   /usr/share/octave/3.4.2/m/audio/wavread.m at line 74, column 5
octave:2> exit

octave:2> Y = wavread("428shortMono.wav")
error: wavread: file contains no RIFF chunk
error: called from:
error:   /pub/hg/octave_build/../octave/scripts/audio/wavread.m at line 
77, column 7

Please note that

$ file *.wav
428shortMono.wav: RIFF (big-endian) data, WAVE audio, mono 44100 Hz
oddchunk.wav:     RIFF (little-endian) data, WAVE audio, Microsoft PCM, 
16 bit, mono 1000 Hz

I am not sure that your file is compatible with octave expectation,
I suggest to rise the question on octave-help as I know nothing about
sound file format.

Regards
Marco

I don't see how setup.exe could downgrade cygwin1.dll if you have
previously installed Cygwin 1.7.9.  setup.exe relies on package metadata
to determine when to replace a package and you don't touch that when you
download a snapshot and copy it to the correct location.

Hmm.  I am obviously confused.  I think I just lost track of what I
was doing, because I was trying to not only set up cygwin on one
computer, but also install it another computer from CD.  Thanks for
clearing that up.

In general, is it risking compatibility problems by updating packages
via setup.exe when you are using a snapshot?

It'll be nice when the new cygwin release comes out and octave works
with gnuplot.  I didn't realize that it was fixed in snapshots after
June.  I know what to try if the need arises.

Yes, my mistake again.  My error message is that there is no RIFF
chunk, while
http://savannah.gnu.org/bugs/?func=detailitem&item_id=30309 is for no
*data* chunk.

Will do.  Thanks for checking for me.
