[gentoo-user] how to downgrade to old fetching indicator?

[Andrew Gaydenko]

Hi!

How to "downgrade" to old fetching indicator (single-line instead of multiple 
lines)?

This has been bugging me for a long time as well, I'd really liek to know 
what's going on.

'ps ax' while emerge is downloading shows the full wget command used - it's 
FETCHCOMMAND from make.conf. The identical command on the command line 
produces the old output. Adding the wget option --progress=bar to 
FETCHCOMMAND changes nothing, but it is the correct option to influence this 
behaviour.

It seems like perhaps FETCHCOMMAND is no longer the applicable setting in 
make.conf...

Perhaps you did not read wget's info page ?
Please read the following excerpt to the end

`--progress=TYPE'
     Select the type of the progress indicator you wish to use.  Legal
     indicators are "dot" and "bar".

     The "bar" indicator is used by default.  It draws an ASCII progress
     bar graphics (a.k.a "thermometer" display) indicating the status of
     retrieval.  If the output is not a TTY, the "dot" bar will be used
     by default.

     Use `--progress=dot' to switch to the "dot" display.  It traces
     the retrieval by printing dots on the screen, each dot
     representing a fixed amount of downloaded data.

     When using the dotted retrieval, you may also set the "style" by
     specifying the type as `dot:STYLE'.  Different styles assign
     different meaning to one dot.  With the `default' style each dot
     represents 1K, there are ten dots in a cluster and 50 dots in a
     line.  The `binary' style has a more "computer"-like
     orientation--8K dots, 16-dots clusters and 48 dots per line (which
     makes for 384K lines).  The `mega' style is suitable for
     downloading very large files--each dot represents 64K retrieved,
     there are eight dots in a cluster, and 48 dots on each line (so
     each line contains 3M).

     Note that you can set the default style using the `progress'
     command in `.wgetrc'.  That setting may be overridden from the
     command line.  The exception is that, when the output is not a
     TTY, the "dot" progress will be favored over "bar".  To force the
     bar output, use `--progress=bar:force'.

So you can try --progress=bar:force

I personally like --progress=dot. And when I download huge files like CD images,
I use wget -b --limit-rate=<MY_DESIRED_RATE_LIMIT> --progress=dot:mega
'http://example.com/foo.tar.lzma'

OK, that explains it. I read the first three paragraphs, saw "Legal indicators 
are 'dot' and 'bar'" and figured there were two options - verbose with lots 
of dots or concise with 50 dashes. That'll teach me to assume :-)

[man wget's is getting like bash, screen, nmap and mplayer's man pages...]

But there's something else at work here - this change happened on my mchine 
within the last 6 weeks. The last emerge of wget here was Aug 17. So what 
changed with portage?

Despair not! Read on! :)

Almost there!

It is, but with a twist. Read the wget manpage again, and you'll find:

  [..] when the output is not a TTY, the "dot" progress will be favored
       over "bar". [..]

So putting --progress=bar:force into FETCHCOMMAND/RESUMECOMMAND does the
trick. Maybe this was done for the --jobs option or a change in background
process logging to a file? No idea but the trick works for me.

When I read the other poster's reply, my first thought was that this is the 
underlying reason - portage traditionally made extensive use of tee in 
dealing with it's output and who knows what that output get connected to.

But this seems to not be the case:

ps axf of the running emerge, which is a regular pts:

13744 pts/1    SN+    0:12  |   |           
\_ /usr/bin/python /usr/bin/emerge -f mozilla-sunbird
13793 pts/1    SN+    0:02  |   |               
\_ /usr/bin/python -O /usr/lib64/portage/bin/ebuild /var/portage/app-office/mozilla-sunbird/mozilla-sunbird-0.9.ebuild 
fetch
13806 pts/1    SN+    0:00  |   |                   \_ wget -t 
5 --passive-ftp --progress=bar 
ftp://ftp.is.co.za/mirror/gentoo.org/distfiles/lightning-sunbird-0.9-source.tar.bz2 -P /var/distfiles


ps ax of the same wget run from a konsole:

13869 pts/1    S+     0:00 wget -t 5 --passive-ftp --progress=bar 
ftp://ftp.is.co.za/mirror/gentoo.org/distfiles/lightning-sunbird-0.9-source.tar.bz2 -P /var/distfiles

Looks the same to me

Sounds plausible. I can't quite see how it was implemented though
