Yes, I think this is the correct conclusion.
I created PDF file using OpenOffice:
Creator:OpenOffice 4.1.2
and flpsed displays the fonts very nice.

The two PFD documents that I created using both versions of Firefox:
www-client/firefox
www-client/firefox-bin

from pdfinfo:
Producer:   cairo 1.9.5 (using Firefox)
Producer:   pdfTeX-1.40.16 (using Firefox)

Both files are having problem viewing fonts using "flpsed".

Cairo should not be part of the problem. It is a vector rendering
library. The part of X.Org that renders text is Pango.

Okay, I think we are getting somewhere now.

If evince shows the documents well, but flpsed does not, it would seem
to me that the documents contain ambiguous font information. The other
PDF viewers [evince, gv, etc.] seem able to resolve the ambiguity, but
flpsed does not. This would indicate that the documents are not well formed.

Can you try another PDF builder, such as LibreOffice or OpenOffice?

If flpsed renders these PDF's well then your PDF builder is at fault. It
is putting into the documents font specifications that do not match the
installed fonts. The other PDF viewers possibly use a fuzzy matching
algorithm that overcomes the ambiguity to select a suitable font.

If I get bored, I may try latest 4.9, 4.10, 4.11 on my "test" machine
and see how it acts there.

I did some googling and didn't find anything that looked like this
problem being reported anywhere -- which makes me wonder what
particular combination of ancient windows server (IIRC, it's 2008) and
odd confguration is causing it.  I have a hard time believing that the
CIFS client in 4.9 kernels can be doing this for very many people...

Ah, of course.  I'm using ~arch kernels ATM.  (As a btrfs user I was tracking 
the most recent upstream stable series, but want to switch to LTS kernels now, 
which happen to be the ones Gentoo stabilizes.  That is, unless a newer kernel

AFAIK that's a (known?) bug.

Sorry, was typing fast. I mean to say the display fonts via flpsed are
not what is shown on wiki pages.

>

It seems to me the problem is the creator of the pdf document (on my
system): pdfTeX-1.40.16 or cairo 1.9.5

Viewing these document via evnce, gv, gimp etc it show normal, nice
fonts; but when I open (same document) locally created via "flpsed" the
fonts are very rough.

When I try to open any other PDF file via "flpsed", not created by me,
the fonts are nice looking.

So, maybe I'm looking in a wrong place.

Here what is on my system:
qlist -C -I texlive

app-text/texlive
app-text/texlive-core
dev-texlive/texlive-basic
dev-texlive/texlive-fontsrecommended
dev-texlive/texlive-fontutils
dev-texlive/texlive-genericrecommended
dev-texlive/texlive-htmlxml
dev-texlive/texlive-langenglish
dev-texlive/texlive-latex
dev-texlive/texlive-latexrecommended
dev-texlive/texlive-metapost
dev-texlive/texlive-pictures
dev-texlive/texlive-texinfo

Maybe I'm missing something.

The flag is named xft. It won't help unless flpsed is written in C++ and
uses the fltk toolkit.

Here ya go.

Reinstalls  target  atoms  and  their  entire  deep dependency tree, as

I read it as a package fails, numba, and emerge stops.  Either way,
sometimes that option doesn't help anyway.  Sometimes emerge has done
all it can and it needs a human fix to carry on.

Try the following, to see what fontconfig has cached:

 fc-list | egrep 'Helvetica' | sort | less

> So which group do they belong to?

The fonts above belong to the package media-fonts/fonts-adobe-75dpi.
These are fonts optimized for rendering on display devices that have a
pixel density of 75 dots per inch (dpi). A qlist for that package
indicates that they do not have a fontconfig .conf file. However,
fontconfig does cache them, since /usr/share/fonts is named in
/etc/fonts/fonts.conf.

> eselect fontconfig list
[snip]

The fonts configured by eselect are "exotic" fonts that are added to
fontconfig. They are of no importance here.

> I don't see anything starting with "helv"

You won't see any such entry.

> Maybe they are not enabled in my system?

Run the fc-list command, as I suggested above. That will show you every
font that purports to offer the Helvetica type face plus any other font
attributes.

Just to show you what to expect from Helvetica and Arial, here are a
couple of Wikipedia articles:

 
 

These articles contain sample text rendered in the respective fonts.
This will help you recognize Helvetica when you get it working.

Would --keepgoing work?   Sometimes that doesn't work, depending on what
packages depend on something that needs to be updated first.  Also,
sometimes --skipfirst comes in handy.

If you copied over /var/db/pkg you have a rather confused and messed up
system. The safest way to recreate it is probably to move the pkg
directory elsewhere and then run "emerge -e @world".

gcc is slotted, so emerging 4.9.4 will not touch your 5.4.0 installation,
you use gcc-config to choose which one to use. What does gcc-config -l
show?

masking packages is the usual way of dealing with this, it is even

Yes, in the past "media-fonts/liberation-fonts"

[gentoo-user] Duplicate rows in "Availble Version" tables at packages.gentoo.org

[Grant Edwards]

Are the "Available Version" tabels at packages.gentoo.org broken?

I've noticed that many of them have more that one row for a particular
version:

For example:

  https://packages.gentoo.org/packages/dev-lang/php

There are two rows for 7.0.15:7.0. One shows all green except for
ia64.  The other is all yellow except for amd64.  I don't remember
seeing this sort of thing in the past, but I won't swear that it's a
new thing either.

[gentoo-user] How to update a system if some packages can't be updated

[Helmut Jarausch]

Hi,
I have packages which can't be updated at the moment, e.g.  
dev-python/numba doesn't work with llvm-4.0.0(_rc3)

But this makes

emerge -uvp --tree --unordered-display --verbose-conflicts --deep  
--with-bdeps=y @world


fail. Is there any means to proceed except masking all those packages  
which can't be currently updated.


Many thanks for a hint,
Helmut

You have a bunch of TrueType fonts in that list. Helvetica is not a
TrueType font, but an Adobe Postscript font. The nearest TrueType font
to Helvetica is probably Arial. However, flpsed is definitely looking
for Helvetica, not Arial.

I would start by deleting the *.ttf files in that directory (or move
them elsewhere) and refreshing the font cache again.

Re: [gentoo-user] Emerge @system causing gcc downgrade

[White, Phil]

Hi Neil,

Well, this is a new install.
Used Stage3-i686-20170214.tar.bz2
There is nothing in package.accept_keywords that is currently installed (as
far as I know - although it is possible that I might have added ~x86 to
gcc, although in this instance I don't believe that i did)
I have installed some packages, but removed them also (been having problems
with perl)
So currently, updating @world is the same as @system

OK - talking this through is helping. I *have* done something strange here.
The currently installed version is 4.9.4 (from gcc --version), except that
portage believes that 5.4.0 is installed.
My guess is that, since I am trying to rebuild an old system (due to a
hard-drive fail), I have accidentally copied over files that do not belong.
My guess is a completely useless /var/db/pkg/* is confusing the hell out of
portage/emerge.

So - any suggestions how to fix this mess?
Bite the bullet, emerge gcc, and then do a depclean - or can I convince
portage that gcc 4.9.4 is really here?

Thanks,
Phil

4.9.4 is the latest stable. Are you running a stable system with some
packages in package.accept_keywords? If so, and you gave a specific
version of gcc, it is possible that version is no longer in the tree -
5.4.0-r2 was recently removed.

Use the ~ operator when specifying versions to allow for minor updates

~sys-devel/gcc-5.4.0

or, in the case of gcc, you can specify a slot

sys-devel/gcc:5.4.0

[gentoo-user] Emerge @system causing gcc downgrade

[White, Phil]

Hi,

I'm sorry. This is probably a really simple question.
I have a new install of Gentoo.
emerge -uDpv --newuse @system results in a new slot for gcc, *downgrading*
the current version (from 5.4.0 to 4.9.4)
No other package is selected for merging.

Why??? What command line can I give to show why a new slot is being pulled
in?
(I wouldn't particularly mind, but as I am on an old x86 celeron, this will
take hours to complete, for no obvious benefit...)

No, as a rule I run stable gentoo-sources, and that's at 4.9.6-r1.

However, I'm a bit confused about the table shown at

  https://packages.gentoo.org/packages/sys-kernel/gentoo-sources

There are two rows for some versions (e.g. 4.9.6-r1), with different
indicators.  What does that mean?

If you're looking for rotating backup solution based on rsync I'd take
a look at rsnapshot.  It is in the Gentoo repo, and it has been
completely dependable in my experience.

You get the same kind of storage you'd expect with plain rsync (just a
replica directory tree that you can freely read, cp from, etc).
However, it does stuff like ensure backups are complete before
rotating them in, handling the rotation itself, and also linking
incremental backups with hard-links to reduce storage.  It isn't quite
de-duplication but it gets you 90% of the benefit vs having a bunch of
complete backup directories that each take up the capacity of a full
backup.  Basically it copies the last backup using hard links, then
rsyncs over that.  The result is what looks like a bunch of full
backups but without all the space use.

If you're looking for something even more space-efficient that is
still based on rsync but which does not store its files as a simple
replica directory tree then look at duplicity, which is also in the
Gentoo repo.  It stores the data in compact archive files like most
other backup solutions, but it uses librsync to do most of the heavy
lifting.  If 1kb changes inside the middle of a 1TB file it only
stores the extra 1kb, just as rsync would only transfer the 1kb.  It
also has a bunch of backend options, including a few cloud services
like S3.  For remote backups it is pretty smart about how it stores
metadata vs data so that if the local cache gets out of sync it can
just re-fetch the metadata from the cloud without having to retrieve
the actual backup data, and it supports gpg.

I personally use both right now.  High-value files are saved using
duplicity to an S3 backend, fully gpg encrypted.  Since I like to mess
with zfs/btrfs I also keep a full replica of those drives locally on
ext4 using rsnapshot.  This is very easy to restore should btrfs eat
my data (and I've made use of it twice).

Rolling your own can certainly be an educational experience, but IMO
it is unnecessary.  Of course, be sure to test recovery no matter how
you end up setting everything up.

Yes, the script clear states there will be 7-backups.
But I see no reason to remove/clear old backup from previous week since
"--delete" will remove all the file on destination that are not in source.

That is just a redundant step, I think.

I also do not know how ReaR parses the path or name of the OS kernel.  If it 
were using your /usr/src/linux/arch/ tree then it would not mind 'x86' in the 
name of the kernel.  Either way, as a workaround you can try renaming the 
kernel image in boot and see if that works - don't forget to update GRUB's 
configuration after you do so.  If ReaR follows symlinks you could just create 
a symlink instead of renaming the kernel.

If you do not want to experiment, then you could ask on the ReaR chat channel 
and see what their devs suggest:

genkernel is free to call a kernel image by any name it feels like
calling it. It's just a file and the only thing the bootloader cares
about is if it can find it.

Therefore rear is out of step, and rear needs to be patched

Re: [gentoo-user] Rear & Genkernel

[White, Phil]

Hi Alan, Thanks for the reply.

First attempt at install was using emerge. This installs version 1.17.1.
This didn't work, so I removed it, and installed version 2.00 from Git, in
an attempt to fix the problem.

BOTH produce the same error - unable to find a kernel due to the naming
issue described previously.
So firstly I need to know whether Genkernel is incorrectly naming the
kernel, or whether Rear is looking for the wrong name.

Cheers,
Phil

Borgbackup seems to check inodes to really fast get a listing of what
files changed. It only needs a few minutes to scan through millions of
files for me, rsync is way slower, and even "find" is slower I feel.
Taking a daily backup of takes usually 8-12 minutes for me (depending
on the delta), thinning the backup set from old backups takes another
1-2 minutes.

Use timestamp check only in rsync, not contents check. This should work
for borgbackup as it is only creating newer files, never older.

No, that's not the trick. Stored files are stored as chunks. Chunks are
split based on a moving window checksumming algorithm to detect
duplicate file blocks. So, deduplication is not done at file level but
subfile level (block level with variable block sizes).

Additionally, those chunks can be compressed with lz4, gzip, and I
think xz (the latter being painfully slow of course).

You don't have to because you can use a more simple filesystem for
borgbackup. I'm storing on xfs and yet plan to sync to remote.
