[libvirt] PATCH: 0/4: Add out-of-memory validation to the testsuite
by Daniel P. Berrange 28 May '08

28 May '08

The following series of patches add infrastructure neccessary to let us test OOM handling for any libvirt code using our malloc wrappers. Currently only a few places use this, but as this series will show, it already lets us find several bugs. As we convert more code away from malloc to VIR_MALLOC we'll get ever improved coverage. Not testing with malloc() directly also means we avoid having to debug code in libraries we link to. Although obviously it'd be nice if they had correct OOM handling, that's their job to debug not ours...

[libvirt] How to add a new Hypervisor support
by Amudhan Gunasekaran 28 May '08

28 May '08

Hi, I am investigating libvirt to find out whether adding a hypervisor support is possible. I went through libvirt.c and found that all the operations are done through the struct virConnect. But virConnect is not exposed to public. So, if I want to add a minimum support for VMWare and Hyper-V hypervisors, is it possible? If it is possible, how should I proceed. Thanks, Amudhan.

[libvirt] [PATCH] plug two sound-related leaks
by Jim Meyering 27 May '08

27 May '08

This fixes the sole remaining leak exposed by "make check" vs. valgrind. Actually it fixes two leaks, but the duplicate sound string one isn't triggered by the tests. >From 495abbe5adcb27187f4831a67f0821d62f36602e Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Thu, 22 May 2008 21:34:19 +0200 Subject: [PATCH] plug two sound-related leaks * src/qemu_conf.c (qemudFreeVMDef): Also free def->sounds.

[Libvir] ISCSI howto, example, etc?
by Mark Dehus 23 May '08

23 May '08

The documentation on the new storage feature is either a little short, or I totally missed it. Anyway, I am looking for some help on how to use it. If anyone could maybe give me an example xml file that would be incredibly helpful, because based on the format description I can't exactly figure out what information I am supposed to put where (for ISCSI). Thanks! -- $ ./Mark

[libvirt] Switch to using lcov for test coverage reports
by Daniel P. Berrange 23 May '08

23 May '08

I got fed up trying to figure out how to fix the coverage reports to merge data from multiple runs correctly, so this patch rips out all our test coverage support. In its place is a makefile rule which just calls out to the lcov program. It requires lcov >= 1.6 since earlier versions were too dumb to deal with .libs/ directories properly. This version has just been submitted to Fedora updates repos.

There's a warning about type-punning in CVS libvirt. We normally rewrite the code generated by glibc rpcgen to avoid these warnings, but because the variable in question has a name containing an uppercase letter, and because the regexp we're using is case-sensitive and only matches lowercase identifiers, the rewrite wasn't happening. Attached patch fixes this. Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines.

[libvirt] PATCH: Misc fixes to qparams
by Daniel P. Berrange 22 May '08

22 May '08

I found a couple more small bugs in the qparams code - In the qparam_query_parse() method, after appending each (name,value) pair of params, it failed to free the temporary buffers for the (name,value) pair. - Did not allow for ';' as a valid query parameter separator - In a couple of OOM cleanup scenarios it failed to free buffers allocated earlier on In looking at this I decide we ought to have a test suite for this code so I'm also including one. It has 100% coverage of all the non-OOM code paths. The test case now passes when run under valgrind [berrange@t60wlan libvirt-numa]$ diffstat .hg/patches/qparam-test b/tests/qparamtest.c | 224 +++++++++++++++++++++++++++++++++++++++++++++ scripts/coverage-report.pl | 3 src/qparams.c | 26 ++++- tests/Makefile.am | 8 + 4 files changed, 253 insertions(+), 8 deletions(-) Dan. diff -r aa244ae10e9e scripts/coverage-report.pl --- a/scripts/coverage-report.pl Wed May 21 19:13:06 2008 -0400 +++ b/scripts/coverage-report.pl Wed May 21 19:42:55 2008 -0400 @@ -65,6 +65,9 @@ } elsif (/^Lines executed:(.*)%\s*of\s*(\d+)\s*$/) { $coverage{$type}->{$name}->{lines} = $2; $coverage{$type}->{$name}->{linesCoverage} = $1; + } elsif (/^No executable lines\s*$/) { + $coverage{$type}->{$name}->{lines} = 0; + $coverage{$type}->{$name}->{linesCoverage} = "100.00"; } elsif (/^Branches executed:(.*)%\s*of\s*(\d+)\s*$/) { $coverage{$type}->{$name}->{branches} = $2; $coverage{$type}->{$name}->{branchesCoverage} = $1; diff -r aa244ae10e9e src/qparams.c --- a/src/qparams.c Wed May 21 19:13:06 2008 -0400 +++ b/src/qparams.c Wed May 21 19:42:55 2008 -0400 @@ -166,7 +166,7 @@ qparam_query_parse (const char *query) { struct qparam_set *ps; - const char *name, *value, *end, *eq; + const char *end, *eq; ps = new_qparam_set (0, NULL); if (!ps) return NULL; @@ -174,9 +174,14 @@ if (!query || query[0] == '\0') return ps; while (*query) { + char *name = NULL, *value = NULL; + /* Find the next separator, or end of the string. */ end = strchr (query, '&'); - if (!end) end = query + strlen (query); + if (!end) + end = strchr (query, ';'); + if (!end) + end = query + strlen (query); /* Find the first '=' character between here and end. */ eq = strchr (query, '='); @@ -191,7 +196,6 @@ */ else if (!eq) { name = xmlURIUnescapeString (query, end - query, NULL); - value = ""; if (!name) goto out_of_memory; } /* Or if we have "name=" here (works around annoying @@ -199,7 +203,6 @@ */ else if (eq+1 == end) { name = xmlURIUnescapeString (query, eq - query, NULL); - value = ""; if (!name) goto out_of_memory; } /* If the '=' character is at the beginning then we have @@ -211,12 +214,23 @@ /* Otherwise it's "name=value". */ else { name = xmlURIUnescapeString (query, eq - query, NULL); + if (!name) + goto out_of_memory; value = xmlURIUnescapeString (eq+1, end - (eq+1), NULL); - if (!name || !value) goto out_of_memory; + if (!value) { + VIR_FREE(name); + goto out_of_memory; + } } /* Append to the parameter set. */ - if (append_qparam (ps, name, value) == -1) goto out_of_memory; + if (append_qparam (ps, name, value ?
