[libvirt] Schedule for next libvirt releases
by Daniel Veillard 17 Nov '10

17 Nov '10

Let's try to keep with end of month based release cycles, so assuming 0.8.6 gets pushed on the 30th, that means 2 weeks from today, and hence we would enter the freeze on Tuesday 23 next week. This means one more week to push patches for 0.8.6. For the following release, I will try to get something out at the end of December, I guess it won't be too hard to do the freeze in the last week, and I will try to make a release for the new year (0.8.7 unless something crazy lands in git in the meantime :-) Happy hacking !

[libvirt] [PATCH] replace last instances of close()
by Stefan Berger 17 Nov '10

17 Nov '10

I am replacing the last instances of close() I found with VIR_CLOSE() / VIR_FORCE_CLOSE respectively. The first patch of virsh I missed out on previously. The 2nd patch I had left out intentionally to look at it more carefully: The 'closed' variable could be easily removed since it wasn't used anywhere else. The possible race condition that could result from the filedescriptor being closed and not set to -1 (and possibly let us write into 'something' totally different if the fd was allocated by another thread) seems to be prevented by the qemuMonitorLock() already placed around the code that reads from or writes to the fd. So the change of this code as shown in the patch should not have any side-effects.

[libvirt] process= support for 'qemu-kvm -name' [Bug 576950]
by John Morrissey 17 Nov '10

17 Nov '10

I wrote (attached here, and to the bug) a quick patch that sets the process name to the same value as the window title. I'm unsure where to go from here. Should I add support for converting "native" QEMU command lines to libvirt XML? What would that look like, since I'm not modifying the libvirt format? Should it just drop any ,process= from the QEMU command line it's parsing? I also imagine the test cases will need updating. If someone could give me some high-level guidance, I'd be happy to keep going on this. john -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

[libvirt] [PATCH] nwfilter: use /bin/sh rather than requiring bash
by Eric Blake 17 Nov '10

17 Nov '10

* src/nwfilter/nwfilter_ebiptables_driver.c (ebiptablesWriteToTempFile): Use /bin/sh. (bash_cmd_path): Delete. (ebiptablesDriverInit, ebiptablesDriverShutdown): No need to search for bash. (CMD_EXEC): Prefer $() over ``, since we can assume POSIX. (iptablesSetupVirtInPost): Use portable 'test' syntax. (iptablesLinkIPTablesBaseChain): Use POSIX $(()) syntax. --- It turns out that the current use of test x == x in nwfilter was technically safe after all, since we were requiring the existence of bash (and that was also relatively reasonable, since nwfilter is only compiled for Linux). But that still feels awkward, when it is easier to just fix things to work with /bin/sh. Here, I went the easy route, and assumed that since things are Linux, we can use shell constructs that aren't strictly portable to all /bin/sh implementations, so long as they are portable to POSIX (and will thus work with dash or busybox sh). src/nwfilter/nwfilter_ebiptables_driver.c | 25 +++++++++++++------------ 1 files changed, 13 insertions(+), 12 deletions(-) diff --git a/src/nwfilter/nwfilter_ebiptables_driver.c b/src/nwfilter/nwfilter_ebiptables_driver.c index 20d1ba3..c3a0d3e 100644 --- a/src/nwfilter/nwfilter_ebiptables_driver.c +++ b/src/nwfilter/nwfilter_ebiptables_driver.c @@ -52,12 +52,16 @@ #define CHAINPREFIX_HOST_IN_TEMP 'J' #define CHAINPREFIX_HOST_OUT_TEMP 'P' +/* This file generates a temporary shell script.

[libvirt] [PATCH] [TCK] nwfilter: add a test case using concurrency
by Stefan Berger 16 Nov '10

16 Nov '10

Now that the existing scripts are (hopefully) cleaned up and my POSIX compliancy shell-scripting skills have temporarily :-) improved, I am now adding a test case that exercises concurrency. The test case creates and destroys 2 VMs concurrently as well as changes their referenced filters in a tight loop. This kind of test previously uncovered - deadlocks in libvirt due to lock-ordering in the nwfilter subsystem - libvirt termination bug in libaugeas due to doubly closed file descriptors and the side effects All of these have been fixed recently. The test script is known to run in bash, dash and ksh shells.

[libvirt] [PATCH v2] [TCK] Convert scripts to also run with dash
by Stefan Berger 16 Nov '10

16 Nov '10

v2: - following Eric's suggestions from review of v1 - runs with ksh shell as well I am converting the shell-scripted tap tests to also run using the dash and ksh shell, fixing some other problems on the way as well. Two of the tests' data files contained '\\1' in an sed command. This created char(1) with the dash, '\1' with the bash. I found it easier to replace the sed command with a different one than figuring out how to solve this escape problem so it works for both shells.

[libvirt] [PATCH v2] deprecate fclose() and introduce VIR_{FORCE_}FCLOSE()
by Stefan Berger 16 Nov '10

16 Nov '10

V2: - following Eric's suggestion, deprecating fdclose(), introducing VIR_FDCLOSE() - following some other nits that Eric pointed out - replaced some more fclose () I previously had missed (last 2 files in patch) Similarly to deprecating close(), I am now deprecating fclose() and introduce VIR_FORCE_FCLOSE() and VIR_FCLOSE(). Also, fdopen() is replaced with VIR_FDOPEN(). Most of the files are opened in read-only mode, so usage of VIR_FORCE_CLOSE() seemed appropriate. Others that are opened in write mode already had the fclose() < 0 check and I converted those to VIR_FCLOSE() < 0. I did not find occurrences of possible double-closed files on the way.
