I've noticed a tendency of my installation code to every now and

When it doesn't crash, I get error messages like this (my own

I can't quite figure it out, but the glob thing is something that
I'll see in the crash stack trace (sporadically). The code used to
install these packages is included below, it seems that every 1 out
of 5 tries, depending on whether or not I am demonstrating the
software to a client, boss, or other person with authority ;)

int installPackage(char *path)
{
fprintf(stderr, "Instaling package located: %s\n", path);
char *files[] = { path };
This line needs to be
char *files[] = { path, NULL };
argv arrays are terminated with NULL.
So your program is wandering off the end-of the array.
For any path arg (and you program wandering found many ;-) that
could not be opened as a *.rpm package, rpmInstall() globs the arg,
inserts into the argv array, and attempts to read as a manifest (i.e. a
list of packages.
rpmts transaction;
struct rpmInstallArguments_s *rpmargs = malloc(sizeof
(struct rpmInstallArguments_s));
bzero(rpmargs, sizeof(struct rpmInstallArguments_s));
rpmargs->installInterfaceFlags = INSTALL_INSTALL |
INSTALL_HASH;
int ret = rpmReadConfigFiles(NULL, NULL);
if (ret != RPMRC_OK)
{
fprintf(stderr, "Unable to read the RPM
configuration!\n");
goto failure;
}
transaction = rpmtsCreate();
ret = rpmInstall(transaction, rpmargs, (const char **)
(files));
if (ret != 0)
{
fprintf(stderr, "Unable to properly install package!
\n");
goto failure;
}
transaction = rpmtsFree(transaction);
free(rpmargs);
return QUERY_SUCCESS;
failure:
transaction = rpmtsFree(transaction);
free(rpmargs);
return QUERY_FAILURE;
}
To see the behavior, assuming you have a foo*.rpm package in
the current directory, do this
echo 'foo*.rpm' > bar.manifest
cat bar.manifest
rpm -ivv bar.manifest
You should see rpmInstall() open bar.manifest, read the glob
pattern, expand the glob, insert the results into the argv array,
and finall install foo*.rpm.
