-# Argument Parsing
-
-## IRC, freenode, #hurd, 2013-06-27
-
- <teythoon> the arg parsing in libdiskfs and libnetfs differ :/
- <teythoon> afaics libdiskfs gets it right, libnetfs does not
- <pinotree> what do you mean?
- <teythoon> wrt to *_std_{runtime,startup}_argp
- <teythoon> see eg netfs.h
- <teythoon> libdiskfs/opts-std-runtime.c:const struct argp
- diskfs_std_runtime_argp =
- <teythoon> libdiskfs/opts-std-runtime.c-{
- <teythoon> libdiskfs/opts-std-runtime.c- std_runtime_options, parse_opt,
- 0, 0, children
- <teythoon> libdiskfs/opts-std-runtime.c-};
- <teythoon> but
- <teythoon> libnetfs/std-runtime-argp.c:const struct argp
- netfs_std_runtime_argp = { 0 };
- <pinotree> well there are no common startup/runtime options provided by
- netfs
- <pinotree> usually netfs-based translators put netfs_std_startup_argp as
- child as their options, so if netfs starts providing options they would
- work
- <teythoon> ah
- <pinotree> if you have a test showing issues, we can certainly look it :)
- <teythoon> ok, m/b I was confused...
- <pinotree> no worries, feel free to ask anytime
- <teythoon> I thought about providing --update as common runtime flag, like
- diskfs does, you think it's the right thing to do?
- <pinotree> what would it do?
- <teythoon> or should it be left for each translator to implement?
- <teythoon> nothing by default I guess
- <pinotree> options provided in libdiskfs are implemented and handled mostly
- in libdiskfs itself
- <pinotree> so imho a new option for libnetfs would be there because its
- behaviour is implemented mostly within libnetfs itself
- <teythoon> libdiskfs calls diskfs_reload_global_state
- <teythoon> libnetfs could do the same, allowing translators to plug in
- anything they wish
- <teythoon> but I'll implement it in procfs for the time being
- <pinotree> ah, its alias is remount
- <teythoon> yes
- <teythoon> I need that working for procfs
- <teythoon> btw, I think I got your mount confusion thing figured out
- <pinotree> but procfs has nothing to update/flush, all the information are
- fetched at every rpc
- <teythoon> yes
- <teythoon> but we still need to ignore the flag
- <teythoon> otherwise the set_options rpc fails
- <teythoon> http://paste.debian.net/12938/
- <teythoon> whee, remounting proc works :)
- <braunr> :)

-# IRC, freenode, #hurd, 2013-07-29
-
- <teythoon> so, what do you folks think about refactoring libdiskfs and
- libnetfs to be more alike?
- <pinotree> what do you mean?
- <teythoon> ah, I mentioned that in the context of my mtab prototype
- 1374247519-26589-1-git-send-email-4winter@informatik.uni-hamburg.de
- <teythoon> they are hard to diff against each other b/c they differ in file
- names and identifier names
- <teythoon> while working on the mtab stuff I encountered stuff that was
- implemented in libdiskfs, but never in libnetfs
- <teythoon> mostly support for binding translators to libnetfs nodes
- <braunr> teythoon: sure, but looks a little out of scope
- <teythoon> braunr: I do not mean now, more in general
- <braunr> ok
- <tschwinge> teythoon: I wondered about this, too. I don't know if it's
- possible to literally merge them (and build the backend-based (libdiskfs)
- vs. volatile-backend one (libnetfs) based on a pre-processor define or
- similar), or just structure the source code (files) in a way such that
- »diff -ru libdiskfs/ libnetfs/« gives meaningful results, figuratively
- spoken.
- <teythoon> tschwinge: my thoughts exactly
-
-
-# IRC, freenode, #hurd, 2013-08-28
-
- <teythoon> braunr: do you think another lib*fs would be frowned uppon? I
- like the way procfs is structured and that could be refactored and
- generalized into a library
- <braunr> i think we need more lib*fs libraries
- <braunr> and better integration
- <braunr> that's one of the strengths in linux
- <braunr> it makes writing file systems very easy
- <teythoon> cool :)
- <teythoon> now we only need a snappy name, any suggestions?
- <braunr> i don't know what you like specificlaly in procfs
- <braunr> libpseudofs ?
- <teythoon> well, it's not perfect, but i like the way you just have to
- implement a function for a node and it magically gains the ability to
- being read
- <teythoon> for example
- <braunr> yes i see
- <pinotree> lacks a bit of caching though
- <braunr> no caching for such file systems
- <teythoon> indeed
- <braunr> why would you want caching ?
- <pinotree> you might have files that don't change at all, or rarely do
- <braunr> the premise is that it's meant for files generated on the fly
- <braunr> but are they big ?
