There is no single -entity involved in all mounts. Rather, only the parent file system to which a -mountpoint ([[hurd/translator]]) is attached is involved. As a result, there -is no central place keeping track of mounts. - -As a consequence, there is currently no easy way to obtain a listing of all -mounted file systems. This also means that commands like `df` can only work on -explicitly specified mountpoints, instead of displaying the usual listing. - -One possible solution to this would be for the translator startup mechanism to -update the `mtab` on any `mount`/`unmount`, like in traditional systems. -However, there are some problems with this approach. Most notably: what to do -with passive translators, i.e., translators that are not presently running, but -set up to be started automatically whenever the node is accessed? Probably -these should be counted among the mounted filesystems; but how to handle the -`mtab` updates for a translator that is not started yet? Generally, being -centralized and event-based, this is a pretty inelegant, non-hurdish solution. - -A more promising approach is to have `mtab` exported by a special translator, -which gathers the necessary information on demand. This could work by -traversing the tree of translators, asking each one for mount points attached -to it. (Theoretically, it could also be done by just traversing *all* nodes, -checking each one for attached translators. That would be very inefficient, -though. Thus a special interface is probably required, that allows asking a -translator to list mount points only.) - -There are also some other issues to keep in mind. Traversing arbitrary -translators set by other users can be quite dangerous -- and it's probably not -very interesting anyways what private filesystems some other user has mounted. -But what about the global `/etc/mtab`? Should it list only root-owned -filesystems? Or should it create different listings depending on what user -contacts it?... - -That leads to a more generic question: which translators should be actually -listed? There are different kinds of translators: ranging from traditional -filesystems ([[disks|hurd/libdiskfs]] and other actual -[[stores|hurd/translator/storeio]]), but also purely virtual filesystems like -[[hurd/translator/ftpfs]] or [[hurd/translator/unionfs]], and even things that -have very little to do with a traditional filesystem, like a -[[gzip_translator|hurd/translator/storeio]], -[[mbox_translator|hurd/translator/mboxfs]], -[[xml_translator|hurd/translator/xmlfs]], or various device file translators... -Listing all of these in `/etc/mtab` would be pretty pointless, so some kind of -classification mechanism is necessary. By default it probably should list only -translators that claim to be real filesystems, though alternative views with -other filtering rules might be desirable. - -After taking decisions on the outstanding design questions, the student will -implement both the actual [[mtab_translator|hurd/translator/mtabfs]], and the -necessary interface(s) for gathering the data. It requires getting a good -understanding of the translator mechanism and Hurd interfaces in general. - -Possible mentors: Olaf Buddenhagen (antrik), Carl Fredrik Hammar (cfhammar) - -Exercise: Make some improvement to any of the existing Hurd translators. -Especially those in [hurdextras](http://www.nongnu.org/hurdextras/) are often -quite rudimentary, and it shouldn't be hard to find something to improve. diff --git a/community/gsoc/project_ideas/valgrind.mdwn b/community/gsoc/project_ideas/valgrind.mdwn index e9e94857..6663eec2 100644 --- a/community/gsoc/project_ideas/valgrind.mdwn +++ b/community/gsoc/project_ideas/valgrind.mdwn @@ -1,4 +1,4 @@ -[[!meta copyright="Copyright © 2009, 2010, 2011 Free Software Foundation, +[[!meta copyright="Copyright © 2009, 2010, 2011, 2013 Free Software Foundation, Inc."]] [[!meta license="""[[!toggle id="license" text="GFDL 1.2+"]][[!toggleable @@ -60,6 +60,8 @@ Such specific semantics can't be deduced from the message headers alone.
