# Stackdriver Debugger API . controller . debuggees . breakpoints

## Instance Methods

Returns the list of all active breakpoints for the debuggee. The breakpoint specification (location, condition, and expression fields) is semantically immutable, although the field values may change. For example, an agent may update the location line number to reflect the actual line where the breakpoint was set, but this doesn't change the breakpoint semantics. This means that an agent does not need to check if a breakpoint has changed when it encounters the same breakpoint on a successive call. Moreover, an agent should remember the breakpoints that are completed until the controller removes them from the active list to avoid setting those breakpoints again.

Updates the breakpoint state or mutable fields. The entire Breakpoint message must be sent back to the controller service. Updates to active breakpoint fields are only allowed if the new value does not change the breakpoint specification. Updates to the `location`, `condition` and `expression` fields should not alter the breakpoint semantics. These may only make changes such as canonicalizing a value or snapping the location to the correct line of code.

### Method Details

`list(debuggeeId, successOnTimeout=None, waitToken=None, x__xgafv=None)`

    Returns the list of all active breakpoints for the debuggee. The breakpoint specification (location, condition, and expression fields) is semantically immutable, although the field values may change. For example, an agent may update the location line number to reflect the actual line where the breakpoint was set, but this doesn't change the breakpoint semantics. This means that an agent does not need to check if a breakpoint has changed when it encounters the same breakpoint on a successive call. Moreover, an agent should remember the breakpoints that are completed until the controller removes them from the active list to avoid setting those breakpoints again.

    Args:
      debuggeeId: string, Identifies the debuggee. (required)
      successOnTimeout: boolean, If set to `true`, returns `google.rpc.Code.OK` status and sets the `wait_expired` response field to `true` when the server-selected timeout has expired (recommended). If set to `false`, returns `google.rpc.Code.ABORTED` status when the server-selected timeout has expired (deprecated).
      waitToken: string, A wait token that, if specified, blocks the method call until the list of active breakpoints has changed, or a server selected timeout has expired. The value should be set from the last returned response.
      x__xgafv: string, V1 error format.

    Returns:
      An object of the form:

        { # Response for listing active breakpoints.
        "waitExpired": True or False, # The `wait_expired` field is set to true by the server when the request times out and the field `success_on_timeout` is set to true.
        "nextWaitToken": "A String", # A wait token that can be used in the next method call to block until the list of breakpoints changes.
        "breakpoints": [ # List of all active breakpoints. The fields `id` and `location` are guaranteed to be set on each breakpoint.
          { # Represents the breakpoint specification, status and results.
            "userEmail": "A String", # E-mail address of the user that created this breakpoint
            "status": { # Represents a contextual status message. The message can indicate an error or informational status, and refer to specific parts of the containing object. For example, the `Breakpoint.status` field can indicate an error referring to the `BREAKPOINT_SOURCE_LOCATION` with the message `Location not found`. # Breakpoint status. The status includes an error flag and a human readable message. This field is usually unset. The message can be either informational or an error message. Regardless, clients should always display the text message back to the user. Error status indicates complete failure of the breakpoint. Example (non-final state): `Still loading symbols...` Examples (final state): * `Invalid line number` referring to location * `Field f not found in class C` referring to condition
              "isError": True or False, # Distinguishes errors from informational messages.
              "refersTo": "A String", # Reference to which the message applies.
              "description": { # Represents a message with parameters. # Status message text.
                "parameters": [ # Optional parameters to be embedded into the message.
                  "A String",
                ],
                "format": "A String", # Format template for the message. The `format` uses placeholders `$0`, `$1`, etc. to reference parameters. `$$` can be used to denote the `$` character. Examples: * `Failed to load '$0' which helps debug $1 the first time it is loaded. Again, $0 is very important.` * `Please pay $$10 to use $0 instead of $1.`
              },
            },
            "logMessageFormat": "A String", # Only relevant when action is `LOG`. Defines the message to log when the breakpoint hits. The message may include parameter placeholders `$0`, `$1`, etc. These placeholders are replaced with the evaluated value of the appropriate expression. Expressions not referenced in `log_message_format` are not logged. Example: `Message received, id = $0, count = $1` with `expressions` = `[ message.id, message.count ]`.
            "variableTable": [ # The `variable_table` exists to aid with computation, memory and network traffic optimization. It enables storing a variable once and reference it from multiple variables, including variables stored in the `variable_table` itself. For example, the same `this` object, which may appear at many levels of the stack, can have all of its data stored once in this table. The stack frame variables then would hold only a reference to it. The variable `var_table_index` field is an index into this repeated field. The stored objects are nameless and get their name from the referencing variable. The effective variable is a merge of the referencing variable and the referenced variable.
              { # Represents a variable or an argument possibly of a compound object type. Note how the following variables are represented: 1) A simple variable: int x = 5 { name: "x", value: "5", type: "int" } // Captured variable 2) A compound object: struct T { int m1; int m2; }; T x = { 3, 7 }; { // Captured variable name: "x", type: "T", members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } 3) A pointer where the pointee was captured: T x = { 3, 7 }; T* p = &x; { // Captured variable name: "p", type: "T*", value: "0x00500500", members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } 4) A pointer where the pointee was not captured: T* p = new T; { // Captured variable name: "p", type: "T*", value: "0x00400400" status { is_error: true, description { format: "unavailable" } } } The status should describe the reason for the missing value, such as ``, ``, `
                  # `. Note that a null pointer should not have members. 5) An unnamed value: int* p = new int(7); { // Captured variable name: "p", value: "0x00500500", type: "int*", members { value: "7", type: "int" } } 6) An unnamed pointer where the pointee was not captured: int* p = new int(7); int** pp = &p; { // Captured variable name: "pp", value: "0x00500500", type: "int**", members { value: "0x00400400", type: "int*" status { is_error: true, description: { format: "unavailable" } } } } } To optimize computation, memory and network traffic, variables that repeat in the output multiple times can be stored once in a shared variable table and be referenced using the `var_table_index` field. The variables stored in the shared table are nameless and are essentially a partition of the complete variable. To reconstruct the complete variable, merge the referencing variable with the referenced variable. When using the shared variable table, the following variables: T x = { 3, 7 }; T* p = &x; T& r = x; { name: "x", var_table_index: 3, type: "T" } // Captured variables { name: "p", value "0x00500500", type="T*", var_table_index: 3 } { name: "r", type="T&", var_table_index: 3 } { // Shared variable table entry #3: members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } Note that the pointer address is stored with the referencing variable and not with the referenced variable. This allows the referenced variable to be shared between pointers and references. The type field is optional. The debugger agent may or may not support it.

`update(debuggeeId, id, body, x__xgafv=None)`

    Updates the breakpoint state or mutable fields. The entire Breakpoint message must be sent back to the controller service. Updates to active breakpoint fields are only allowed if the new value does not change the breakpoint specification. Updates to the `location`, `condition` and `expression` fields should not alter the breakpoint semantics. These may only make changes such as canonicalizing a value or snapping the location to the correct line of code.

    Args:

The status includes an error flag and a human readable message. This field is usually unset. The message can be either informational or an error message. Regardless, clients should always display the text message back to the user. Error status indicates complete failure of the breakpoint.

            { # Represents a variable or an argument possibly of a compound object type. Note how the following variables are represented: 1) A simple variable: int x = 5 { name: "x", value: "5", type: "int" } // Captured variable 2) A compound object: struct T { int m1; int m2; }; T x = { 3, 7 }; { // Captured variable name: "x", type: "T", members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } 3) A pointer where the pointee was captured: T x = { 3, 7 }; T* p = &x; { // Captured variable name: "p", type: "T*", value: "0x00500500", members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } 4) A pointer where the pointee was not captured: T* p = new T; { // Captured variable name: "p", type: "T*", value: "0x00400400" status { is_error: true, description { format: "unavailable" } } } The status should describe the reason for the missing value, such as ``, ``, `
                # `. Note that a null pointer should not have members. 5) An unnamed value: int* p = new int(7); { // Captured variable name: "p", value: "0x00500500", type: "int*", members { value: "7", type: "int" } } 6) An unnamed pointer where the pointee was not captured: int* p = new int(7); int** pp = &p; { // Captured variable name: "pp", value: "0x00500500", type: "int**", members { value: "0x00400400", type: "int*" status { is_error: true, description: { format: "unavailable" } } } } } To optimize computation, memory and network traffic, variables that repeat in the output multiple times can be stored once in a shared variable table and be referenced using the `var_table_index` field. The variables stored in the shared table are nameless and are essentially a partition of the complete variable. To reconstruct the complete variable, merge the referencing variable with the referenced variable. When using the shared variable table, the following variables: T x = { 3, 7 }; T* p = &x; T& r = x; { name: "x", var_table_index: 3, type: "T" } // Captured variables { name: "p", value "0x00500500", type="T*", var_table_index: 3 } { name: "r", type="T&", var_table_index: 3 } { // Shared variable table entry #3: members { name: "m1", value: "3", type: "int" }, members { name: "m2", value: "7", type: "int" } } Note that the pointer address is stored with the referencing variable and not with the referenced variable. This allows the referenced variable to be shared between pointers and references. The type field is optional. The debugger agent may or may not support it.

This field will usually stay unset. A status of a single variable only applies to that variable or expression. The rest of breakpoint data still remains valid. Variables might be reported in error state even when breakpoint is not in final state. The message may refer to variable name with `refers_to` set to `VARIABLE_NAME`. Alternatively `refers_to` will be set to `VARIABLE_VALUE`. In either case variable value and members will be unset. Example of error message applied to name: `Invalid expression syntax`.
