 Posted: Mon Jan 06, 2003 4:03 am Post subject: Should I fear this freetype downgrade? |
 |
|
Hi,
Now that I know that the 'D' in emerge --pretend stands for "Downgrade" (See: What are the letters in "[ebuild N]"?), the question begs why does emerge want to downgrade my current version of freetype, and will doing so break anything?...
| Code: | # emerge -p mod_php
These are the packages that I would merge, in order:
Calculating dependencies ...done!
[ebuild N ] media-libs/pdflib-4.0.3
[ebuild N ] app-crypt/mhash-0.8.16
[ebuild N ] sys-apps/supersed-3.58-r2
[ebuild UD] media-libs/freetype-1.3.1-r3 [2.1.2-r2]
[ebuild N ] media-libs/libgd-1.8.3-r5
[ebuild N ] app-text/sablotron-0.95-r1
[ebuild N ] dev-libs/libmcrypt-2.5.5
[ebuild N ] net-libs/libwww-5.4.0-r1
[ebuild N ] dev-php/mod_php-4.2.3-r2 |
It seems that 2.1.2-r2 is the latest version, and is not masked?...
| Code: | # emerge -s freetype
Searching...
* media-libs/freetype

Ok here is the relavant portion of the ebuild
DEPEND="
>=net-www/apache-1.3.26-r2
freetype? ( ~media-libs/freetype-1.3.1 >=media-libs/t1lib-1.3.1 )
jpeg? ( >=media-libs/jpeg-6b )
tiff? ( >=media-libs/tiff-3.5.5 )
png? ( >=media-libs/libpng-1.2.1 )
gd? ( >=media-libs/libgd-1.8.3 )
X? ( virtual/x11 )
qt? ( x11-libs/qt )
So first off freetype is an optional compnient that can be turned off using the -freetype USE option.
you could also try the following...
DEPEND="
>=net-www/apache-1.3.26-r2
freetype? ( >=media-libs/t1lib-1.3.1 )
jpeg? ( >=media-libs/jpeg-6b )
tiff? ( >=media-libs/tiff-3.5.5 )
png? ( >=media-libs/libpng-1.2.1 )
gd? ( >=media-libs/libgd-1.8.3 )
X? ( virtual/x11 )
qt? ( x11-libs/qt )
And see if it works. |

This all doesn't make sense as Freetype 1 and Freetype 2 really are 2 different 'resourses' and IMO should be structured in 2 different packages in Portage.
Here's what is said on freetype.org about the 2:
Freetype 1:
| Code: | | Note that FreeType 1 is a [i]library[/i]. It is not a font server for your favorite platform, even though it was designed to be used in many of them. Note also that it is not a complete text-rendering library. Its purpose is simply to open and manage font files, as well as load, hint and render individual glyphs efficiently. You can also see it as a "TrueType driver" for a higher-level library, though rendering text with it is easy, as demonstrated by the test programs. |
Freetype 2:
| Code: | | Note that FreeType 2 is a[i] font service [/i]and doesn't provide APIs to perform higher-level features, like text layout or graphics processing (e.g. colored text rendering, "hollowing", etc..). However, it greatly simplifies these tasks by providing a simple, easy to use and uniform interface to access the content of font files. |
I think also PHP really distinguage between the two, refering to FT1 as 'ttf' (or similar) and FT2 as 'freetype' which also would mean the ebuilds deps on freetype are erronic. Also, if looking at /usr/portage/profiles/use.desc there is no 'freetype' use variable.
Well I just thought is all looked strange as portage also wanted to downgrade my freetype2 on a -u --deep world. Anyhow I think this really is a candidate for bugzilla! 
EDIT:
I took a run over to php.net and checked up on this and here it is from docs...
| php docs wrote: | --with-freetype-dir=DIR
GD: Set the path to freetype2 install prefix.
--with-ttf[=DIR]
GD: Include FreeType 1.x support.
--with-t1lib[=DIR]
GD: Include T1lib support. |
I'm not sure really what the T1lib support is, if it have anything to do with Truetype 1 or not.
Anyhow, Think I have enough here to fire a report at bugzilla

If you look more closely at the ebuild you will notice that freetype is "sloted" in that you can have freetype 1.x and freetype 2.x both installed at the same time.

So what you are saying is that if he performs this emerge, it will not ruin or uninstall his current freetype?
What if he does a 'emerge -clean' in the future? Will bad things happen?
(I want to know because the emerge plan for waimea is showing me the same freetype 'downgrade'.) |

Slots means that both freetype-1.x.x and freetype-2.x.x are recognized by Portage and are handled as separate packages; freetype-1.x.x will not upgrade to freetype-2.x.x, and if a new version of freetype-1.x.x comes out, the old one will be replaced but freetype-2.x.x will be unaffected.
Portage is smart.

If this is the case the emerge --pretend output is very misleading. To me "[ebuild UD] media-libs/freetype-1.3.1-r3 [2.1.2-r2]" implies replacing 2.1.2-r2 with 1.3.1-r3. If all it is doing is merging 1.3.1-r3 into a different slot it should just read, "[ebuild N ] media-libs/freetype-1.3.1-r3" (if you ask me). |

It works perfectly as delta407 advertised.

For what it's worth, I agree. This is misleading and should be registered as a bug. |

I filed a bug (https://bugs.gentoo.org/show_bug.cgi?id=13382), not really about the downgrading of Freetype though, but the way it and php are set up in connection with each other. The php ebuilds have a use varable 'freetype', but there is no "official" use variable 'freetype' (in use.desc). There is a 'truetype' use variable though. However, while the ebuild script uses freetype to define freetype1, php it self uses the term truetype for freetype1 and t1lib. Within php the term freetype is used to define Freetype2 and not freetype1.
I think the slot system is great many times, but when it comes to Freetype it's really a qustion of to different packages Freetype1 and Freetype2 and not Freetype version 1 & 2 - Well that's my opinion about it and slots shouldn't be used here.

I hacked my ebuilds for php so that it only links to freetype 2:
| Code: |
- truetype? ( ~media-libs/freetype-1.3.1 >=media-libs/t1lib-1.3.1 )
+ truetype? ( ~media-libs/freetype-2.1.2-r2 >=media-libs/t1lib-1.3.1 )
- use truetype && myconf="${myconf} --with-ttf --with-t1lib"
+ use truetype && myconf="${myconf} --with-freetype --with-freetype-dir=/usr/lib --with-t1lib"
|
and with ldd:
| Code: |
dma@laureate:/usr/lib/apache-extramodules$ ldd libphp4.so
...
libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x42077000)
...
|
And freetype 1.x is history.
And it works too. In fact, I hacked it because freetype 1.x didn't work at all on my box. |

I'm not 100% sure, but almost... I would do it like
| Code: |
- truetype? ( ~media-libs/freetype-1.3.1 >=media-libs/t1lib-1.3.1 )
+ truetype? ( >=media-libs/freetype-2.1.2 )
- use truetype && myconf="${myconf} --with-ttf --with-t1lib"
+ use truetype && myconf="${myconf} --with-freetype-dir=/usr/lib"
|
as 't1lib' is all for trutype1 and rendering in X and have notting to do with trutype2 - if I have understand things right.
