[gentoo-dev] USE flags again (informix, memlimit)

[gentoo-dev] USE flags again (informix, memlimit)

[Robin H.Johnson]

[-- Attachment #1: Type: text/plain, Size: 1573 bytes --]

I've almost completed the new PHP eclasses for mod_php and CLI php.
I just wanted to discuss a possible new global USE flag.

informix - Provides support for IBM Informix server

This would compliment the current 'oci8' for Oracle.
Once we also get other packages for informix, then will greatly increase
our appeal to the enterprise market :-).

Previously, Tal (coredumb) made enquries about the a memlimit flag on
-core. (Subject: '[gentoo-core] Memory limit useflag' Date: 23? Apr).
Nobody at all responded to the message, so I'm going to just repeat the
just of it here.

This was originally in response to bug #18890. PHP supports a memory
limit option that puts some memory usage limits into place (similar to
ulimit).

We want to push this to a USE flag as it does cause a visible
performance hit for the increase in security it provides.

From a little research on Google, it seems that both TeX and PostGres
support memory limit stuff to some degree (I did not dig much beyond the
first page linked off google).

Any comments about it? Notes that other packages support a memory limit
would be helpful too.

Given the utter lack of response to Tal's previous email to -core, if I
don't get any answer on these by saturday, I'll look at including them
myself as they are needed for the new PHP ebuilds.

In my opinion USE flags should stay local as long as there's not
multiple uses for it currently available (or pending) in the tree . I
don't know if that's the case here (taking into consideration php and
mod_php are basically the same package).

wouldn't be a general security type of flag better ? In general it seems
like the sort of thing flagged.

see it like this, other devs don't deal with your packages and may be
careful to give their opinion about something they haven't looked into
(i know i am).

In general i was looking trough USE flags list, things like icc and
jikes and memlimit maybe, do they really belong in use.desc ? Aren't USE
flags defined as compile time enabling or disabling of certain features
in an application, i guess memlimit fits the description, but icc and
jikes don't, theyre compile time options that have no direct effect on
the functionality of the app. Shouldnt they have their own file,
removing some of the burden of the use.desc file ?

Icc adds extra dependencies, since the binary must be run with icc
installed, since it links to icc libraries. so its both a compile time
and a runtime dependency.

jikes, I dont know about, neither about the haskell compiler choice
flags.

Ofcourse they do have deps, but so does our standard compiler (we don't
have gcc listed in every ebuild). I do not question their existance, i
question their position in comparison to most other USE flags, compiling
options (how do you want to compile) vs. compile time options (what do
you want to compile exactly = USE). The suggested division is just a
superficial one.

Informix is supported by 
dev-java/jdbc-informix
net-www/cocoon

But neither of those need the informix USE flag, however Informix is
supported in general.

Any suggested names? Postgres and TeX seem to have it because they can
get big easily, not for security reasons.

I don't expect that they have looked into my packages deeply, but I was
looking for response regarding these flags and their packages (which I
haven't looked deeply at).

Is the performance of the app not part of it's functionality? If so,
then icc has a use. Likewise for jikes.
