The problem seems to come from svn_rangelist_merge2.
This test program recreates the problem.
#include <svn_pools.h>
#include <svn_mergeinfo.h>
int main(int argc, char * argv[])
{
apr_pool_t *pool;
int exit_code = EXIT_SUCCESS;
svn_error_t *err;
if (svn_cmdline_init("svn", stderr) != EXIT_SUCCESS)
return EXIT_FAILURE;
pool = apr_allocator_owner_get(svn_pool_create_allocator(FALSE));
// 15014-19472,19473-19612*,19613-19614,19615-19630*,19631-19634,19635-20055*
svn_rangelist_t * rangelist = apr_array_make(pool, 1, sizeof(svn_merge_range_t *));
svn_merge_range_t *mrange = apr_pcalloc(pool, sizeof(*mrange));
mrange->start = 15013;
mrange->end = 19472;
mrange->inheritable = TRUE;
APR_ARRAY_PUSH(rangelist, svn_merge_range_t *) = mrange;
mrange = apr_pcalloc(pool, sizeof(*mrange));
mrange->start = 19472;
mrange->end = 19612;
mrange->inheritable = FALSE;
APR_ARRAY_PUSH(rangelist, svn_merge_range_t *) = mrange;
mrange = apr_pcalloc(pool, sizeof(*mrange));
mrange->start = 19612;
mrange->end = 19614;
mrange->inheritable = TRUE;
APR_ARRAY_PUSH(rangelist, svn_merge_range_t *) = mrange;
mrange = apr_pcalloc(pool, sizeof(*mrange));
mrange->start = 19614;
mrange->end = 19630;
mrange->inheritable = FALSE;
APR_ARRAY_PUSH(rangelist, svn_merge_range_t *) = mrange;
mrange = apr_pcalloc(pool, sizeof(*mrange));
mrange->start = 19630;
mrange->end = 19634;
mrange->inheritable = TRUE;
APR_ARRAY_PUSH(rangelist, svn_merge_range_t *) = mrange;
mrange = apr_pcalloc(pool, sizeof(*mrange));
mrange->start = 19634;
mrange->end = 20055;
mrange->inheritable = FALSE;
APR_ARRAY_PUSH(rangelist, svn_merge_range_t *) = mrange;
// 15014-20515*
svn_rangelist_t * changes = apr_array_make(pool, 1, sizeof(svn_merge_range_t *));
mrange = apr_pcalloc(pool, sizeof(*mrange));
mrange->start = 15013;
mrange->end = 20515;
mrange->inheritable = FALSE;
APR_ARRAY_PUSH(changes, svn_merge_range_t *) = mrange;
{
svn_string_t * tmpString;
svn_rangelist_to_string(&tmpString, rangelist, pool);
printf("rangelist %s\n", tmpString->data);
}
{
svn_string_t * tmpString;
svn_rangelist_to_string(&tmpString, changes, pool);
printf("changes %s\n", tmpString->data);
}
svn_rangelist_merge2(rangelist, changes, pool, pool);
{
svn_string_t * tmpString;
svn_rangelist_to_string(&tmpString, rangelist, pool);
printf("result %s\n", tmpString->data);
}
// wrong result
// result 15014-19472,19473-19612*,19613-19614,19615-19630*,19634-19631*,19631-19634,19635-20515*
svn_pool_destroy(pool);
return exit_code;
}
So while this correctly expands the last range from 20055 to 20515 it inserts a wrong inverse range. It’s a bit late, I’ll have a look tomorrow unless someone beats me to it. ;)
