Functions | |
svn_error_t * | svn_error_create (apr_status_t apr_err, svn_error_t *child, const char *message) |
Create a nested exception structure. | |
svn_error_t * | svn_error_createf (apr_status_t apr_err, svn_error_t *child, const char *fmt,...) __attribute__((format(printf |
Create an error structure with the given apr_err and child, with a printf-style error message produced by passing fmt, using apr_psprintf(). | |
svn_error_t * | svn_error_wrap_apr (apr_status_t status, const char *fmt,...) __attribute__((format(printf |
Wrap a status from an APR function. | |
svn_error_t * | svn_error_quick_wrap (svn_error_t *child, const char *new_msg) |
A quick n' easy way to create a wrapped exception with your own message, before throwing it up the stack. | |
void | svn_error_compose (svn_error_t *chain, svn_error_t *new_err) |
Add new_err to the end of chain's chain of errors. | |
svn_error_t * | svn_error_root_cause (svn_error_t *err) |
Return the root cause of err by finding the last error in its chain (e.g. | |
svn_error_t * | svn_error_dup (svn_error_t *err) |
Create a new error that is a deep copy of err and return it. | |
void | svn_error_clear (svn_error_t *error) |
Free the memory used by error, as well as all ancestors and descendants of error. | |
void | svn_handle_error2 (svn_error_t *error, FILE *stream, svn_boolean_t fatal, const char *prefix) |
Very basic default error handler: print out error stack error to the stdio stream stream, with each error prefixed by prefix, and quit iff the fatal flag is set. | |
void | svn_handle_error (svn_error_t *error, FILE *stream, svn_boolean_t fatal) |
Like svn_handle_error2() but with prefix set to "svn: ". | |
void | svn_handle_warning2 (FILE *stream, svn_error_t *error, const char *prefix) |
Very basic default warning handler: print out the error error to the stdio stream stream, prefixed by prefix. | |
void | svn_handle_warning (FILE *stream, svn_error_t *error) |
Like svn_handle_warning2() but with prefix set to "svn: ". |
void svn_error_clear | ( | svn_error_t * | error | ) |
Free the memory used by error, as well as all ancestors and descendants of error.
Unlike other Subversion objects, errors are managed explicitly; you MUST clear an error if you are ignoring it, or you are leaking memory. For convenience, error may be NULL
, in which case this function does nothing; thus, svn_error_clear(svn_foo(...)) works as an idiom to ignore errors.
void svn_error_compose | ( | svn_error_t * | chain, | |
svn_error_t * | new_err | |||
) |
Add new_err to the end of chain's chain of errors.
The new_err chain will be copied into chain's pool and destroyed, so new_err itself becomes invalid after this function.
svn_error_t* svn_error_create | ( | apr_status_t | apr_err, | |
svn_error_t * | child, | |||
const char * | message | |||
) |
Create a nested exception structure.
Input: an APR or SVN custom error code, a "child" error to wrap, a specific message
Returns: a new error structure (containing the old one).
NULL
if there is nothing to add to the general message associated with the error code.NULL
for the child argument.
svn_error_t* svn_error_dup | ( | svn_error_t * | err | ) |
Create a new error that is a deep copy of err and return it.
svn_error_t* svn_error_quick_wrap | ( | svn_error_t * | child, | |
const char * | new_msg | |||
) |
A quick n' easy way to create a wrapped exception with your own message, before throwing it up the stack.
(It uses all of the child's fields.)
svn_error_t* svn_error_root_cause | ( | svn_error_t * | err | ) |
Return the root cause of err by finding the last error in its chain (e.g.
it or its children). err may be SVN_NO_ERROR
, in which case SVN_NO_ERROR
is returned.
svn_error_t* svn_error_wrap_apr | ( | apr_status_t | status, | |
const char * | fmt, | |||
... | ||||
) |
Wrap a status from an APR function.
If fmt is NULL, this is equivalent to svn_error_create(status,NULL,NULL). Otherwise, the error message is constructed by formatting fmt and the following arguments according to apr_psprintf(), and then appending ": " and the error message corresponding to status. (If UTF-8 translation of the APR error message fails, the ": " and APR error are not appended to the error message.)
void svn_handle_error | ( | svn_error_t * | error, | |
FILE * | stream, | |||
svn_boolean_t | fatal | |||
) |
Like svn_handle_error2() but with prefix
set to "svn: ".
void svn_handle_error2 | ( | svn_error_t * | error, | |
FILE * | stream, | |||
svn_boolean_t | fatal, | |||
const char * | prefix | |||
) |
Very basic default error handler: print out error stack error to the stdio stream stream, with each error prefixed by prefix, and quit iff the fatal flag is set.
Allocations are performed in the error's pool.
If you're not sure what prefix to pass, just pass "svn: ". That's what code that used to call svn_handle_error() and now calls svn_handle_error2() does.
void svn_handle_warning2 | ( | FILE * | stream, | |
svn_error_t * | error, | |||
const char * | prefix | |||
) |
Very basic default warning handler: print out the error error to the stdio stream stream, prefixed by prefix.
Allocations are performed in the error's pool.
