It has however +a long-term vaporware reputation; development has indeed been relatively +dormant for some time, but recent regain of interest has brought interesting +improvements and stabilization, to the point that there will be a non-official +release of the GNU/Hurd variant of Debian Wheezy, with about 75% of the Debian +packages, including classical graphical desktop application (gnome, gnumeric, +firefox, ...) + +This talk will present to GNU/Hurd in general and its "translator" mechanism +which replaces the traditional notion of filesystem by userland processes, so +as to provide strong flexibility to users and administrators, and we will demo +it live. The subhurd/neighborhurd mechanism, a very natural way to provide +virtualization container support on GNU/Hurd, will also be presented. We will +also present recent developments, notably in terms of DDE device drivers run as +userland processes, and discuss about maintenance of DDE. + +Duration: +30m, 45m? diff --git a/hurd/translator/procfs/jkoenig/discussion.mdwn b/hurd/translator/procfs/jkoenig/discussion.mdwn index 612983db..cca9c3f3 100644 --- a/hurd/translator/procfs/jkoenig/discussion.mdwn +++ b/hurd/translator/procfs/jkoenig/discussion.mdwn @@ -299,6 +299,8 @@ Needed by glibc's `pldd` tool (commit with nocheck (ie skipping the test suite run) instead of investigate and report why the test suite failed +[[!GNU_Savannah_bug 32770]] + # IRC, freenode, #hurd, 2011-06-19 diff --git a/open_issues/glibc.mdwn b/open_issues/glibc.mdwn index 24fe8026..e2b968c9 100644 --- a/open_issues/glibc.mdwn +++ b/open_issues/glibc.mdwn @@ -220,7 +220,7 @@ Last reviewed up to the [[Git mirror's d3bd58cf0a027016544949ffd27300ac5fb01bb8 `open_by_handle_at`, `process_vm_readv`, `process_vm_writev`, `sendmmsg`, `setns`, `sync_file_range` - Check also the content of `gnu/stubs-32.h`, which lists all the functions + Check also the content of `gnu/stubs.h`, which lists all the functions marked as stub which only return `ENOSYS`. * `chflags` @@ -305,10 +305,6 @@ Last reviewed up to the [[Git mirror's d3bd58cf0a027016544949ffd27300ac5fb01bb8 * [[`mremap`|mremap]] - * `syncfs` - - We should be easily able to implement that one. - * `futimesat` If we have all of 'em (check Linux kernel), `#define __ASSUME_ATFCTS`. @@ -839,9 +835,9 @@ Last reviewed up to the [[Git mirror's d3bd58cf0a027016544949ffd27300ac5fb01bb8 kinds of unused configuration options and dead code.`). `NO_STARTER` changes (should be OK). * [high] `pagesize`, 02d46fc4b969e25e4ba0c54aa95fa98d7279bd05 (`Simplify - malloc initialization`); aebae0537dcb408100b88c6b7647a7e858c43237, `BZ - 11929`.
