[libvirt] PATCH: Convert buf.c to use memory alloc wrappers

This patch coverts the virBuffer code over to using our internal memory allocation wrappers. It then fixes a bug in xend_internal.c where it was failing to check for allocation failure, although this was technically completely harmless, since the virBuffer routines already protected against this specific scenario. src/buf.c | 16 ++++++---------- src/xend_internal.c | 4 ++++ 2 files changed, 10 insertions(+), 10 deletions(-) Dan diff -r 797f37ce08c2 src/buf.c --- a/src/buf.c Wed May 21 22:22:48 2008 -0400 +++ b/src/buf.c Thu May 22 11:42:32 2008 -0400 @@ -21,6 +21,7 @@ #define __VIR_BUFFER_C__ #include "buf.h" +#include "memory.h" /* If adding more fields, ensure to edit buf.h to match @@ -42,8 +43,7 @@ static void virBufferNoMemory(const virBufferPtr buf) { - free(buf->content); - buf->content = NULL; + VIR_FREE(buf->content); buf->size = 0; buf->use = 0; buf->error = 1; @@ -62,7 +62,6 @@ virBufferGrow(virBufferPtr buf, unsigned int len) { int size; - char *newbuf; if (buf->error) return -1; @@ -72,12 +71,10 @@ size = buf->use + len + 1000; - newbuf = realloc(buf->content, size); - if (newbuf == NULL) { + if (VIR_REALLOC_N(buf->content, size) < 0) { virBufferNoMemory(buf); return -1; } - buf->content = newbuf; buf->size = size; return 0; } @@ -271,8 +268,7 @@ return; len = strlen(str); - escaped = malloc(5 * len + 1); - if (escaped == NULL) { + if (VIR_ALLOC_N(escaped, 5 * len + 1) < 0) { virBufferNoMemory(buf); return; } @@ -316,14 +312,14 @@ buf->content[buf->use] = 0; grow_size = (count > 1000) ? count : 1000; if (virBufferGrow(buf, grow_size) < 0) { - free(escaped); + VIR_FREE(escaped); return; } size = buf->size - buf->use - 1; } buf->use += count; buf->content[buf->use] = '\0'; - free(escaped); + VIR_FREE(escaped); } /** diff -r 797f37ce08c2 src/xend_internal.c --- a/src/xend_internal.c Wed May 21 22:22:48 2008 -0400 +++ b/src/xend_internal.c Thu May 22 11:42:32 2008 -0400 @@ -924,6 +924,10 @@ // and build with all available models if (STREQ(model, "all")) { int i; + if (virBufferError(&buf)) { + free(model); + goto error; + } free(virBufferContentAndReset(&buf)); for (i=0; i < sizeof(sound_models)/sizeof(*sound_models); ++i) -- |: Red Hat, Engineering, Boston -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
