[Libvir] PATCH: Autogenerate table of contents for docs
by Daniel P. Berrange 30 Apr '08

30 Apr '08

Alot of the docs pages have manually written table of contents linking to headings with the page. I figured this is a good candidate for being auto-generated. The basic idea is that given a document with a series of headings <h2><a name="xxx">Foo</a></h2> .. <h3><a name="xxx">Bar</a></h3> .. <h3><a name="xxx">Wizz</a></h3> .. <h2><a name="xxx">Oooh</a></h2> .. <h3><a name="xxx">Ahhh</a></h3> Then, generate a table of contents with a nested set of lists <ul>. THe XSL below attempts todo this for heading levels h2 -> h6, and splices the TOC into the page where it sees an <ul id='toc'></ul> element (typically just after <h1>). I'm kind of out of practice with XSL, so there's probably a nicer way to write the 'toc' template below... Dan.

[Libvir] [PATCH] remove useless tests before xmlFree

29 Apr '08

I've just fixed a bug in my useless-if-detecting script, committed in gnulib. Using that new script with today's change adding xmlFree to the list exposed a bunch of useless tests. This first change set removes those tests. Below it is a separate patch that updates gnulib-related files, including that script and vc-list-files. I verified that with these changes "make distcheck" passes.

[Libvir] PATCH: Avoid buffer out of bounds access in Xen capabilities
by Daniel P. Berrange 29 Apr '08

29 Apr '08

The Xen driver uses a regex to process the hypervisor capabilities data "(xen|hvm)-[[:digit:]]+\\.[[:digit:]]+-(x86_32|x86_64|ia64|powerpc64)(p|be)?"; notice how the last match group, however, is optional due to the '?'. The code processing matches does not check to see if the match is present or not, and just indexes the string on match 3 if (strncmp (&token[subs[3].rm_so], "p", 1) == 0) Unfortunately, subs[3].rm_so is -1 if the match was not present, so we're doing an out of bounds array access here. This is fairly harmless, but it is still good to fix it. So this patch adds a check for -1 before accessing the match. I also replace the strncmp() calls with a call to the brand new STRPREFIX() convenience macro Dan.
