[libvirt] process= support for 'qemu-kvm -name' [Bug 576950]
by John Morrissey 16 Nov '10

16 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 16 Nov '10

16 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 15 Nov '10

15 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.

This has been optional in netcf for awhile, but the change hadn't been propogated to the libvirt copy of the RNG. --- I noticed this was out of date while updating the netcf RNG with the new regex for ipv4-address.

[libvirt] [PATCH] [TCK] Convert scripts to also run with dash
by Stefan Berger 15 Nov '10

15 Nov '10

I am converting the shell-scripted tap tests to also run using the dash 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] macvtap: convert send / recv function to use libnl

-V2: - adapting patch due to changes in the same file by another patch In a second step I am converting the netlink send/receive functions to use libnl. I tested this with 802.1Qbg profiles and my test server and did not see a regression.

[libvirt] [PATCH] RFC: Remove all object hashtable caches from virConnectPtr
by Daniel P. Berrange 15 Nov '10

15 Nov '10

The virConnectPtr struct will cache instances of all other objects. APIs like virDomainLookupByUUID will return a cached object, so if you do virDomainLookupByUUID twice in a row, you'll get the same exact virDomainPtr instance. This does not have any performance benefit, since the actual logic in virDomainLookupByUUID (and other APIs returning virDomainPtr, etc instances) is not short-circuited. All it does is to ensure there is only one single virDomainPtr in existance for any given UUID. The caching has a number of downsides though, all relating to stale data. If APIs aren't careful to always overwrite the 'id' field in virDomainPtr it may become out of data. Likewise for the name field, if a guest is renamed, or if a guest is deleted, and then a new one created with the same UUID but different name. This has been an ongoing, endless source of bugs for all applications using libvirt from languages with garbage collection, causing them to get virDomainPtr instances from long ago with stale data. The caching is also a waste of memory resources, since both applications, and language bindings often maintain their own hashtable caches of object instances. This patch removes all the hash table caching, so all APIs return brand new virDomainPtr (etc) object instances. Other options include - Explicitly overrite the 'name' field in the cached objects every time they are looked up, to ensure fully up2date objects - Add a flag to virConnectOpen to allow apps to turn off caching themselves. * src/datatypes.h: Delete all hash tables. * src/datatypes.c: Remove all object caching code --- src/datatypes.c | 657 +++++++++++++------------------------------------------ src/datatypes.h | 10 - 2 files changed, 149 insertions(+), 518 deletions(-) diff --git a/src/datatypes.c b/src/datatypes.c index 46009ae..66dbc99 100644 --- a/src/datatypes.c +++ b/src/datatypes.c @@ -41,120 +41,6 @@ * * ************************************************************************/ -/** - * virDomainFreeName: - * @domain: a domain object - * - * Destroy the domain object, this is just used by the domain hash callback. - * - * Returns 0 in case of success and -1 in case of failure. - */ -static int -virDomainFreeName(virDomainPtr domain, const char *name ATTRIBUTE_UNUSED) -{ - return (virUnrefDomain(domain));
