search in docstrings

Search bar offers the following options:

- Term presence. The below example searches for documents that must contain “foo”, might contain “bar” and must not contain “baz”: `+foo bar -baz`
- Wildcards. The below example searches for documents with words beginning with “foo”: `foo*`
- Search in specific fields. The following search matches all objects in "twisted.mail" that matches “search”: `+qname:twisted.mail.* +search`

  Possible fields: 'name', 'qname' (fully qualified name), 'docstring', and 'kind'. Last two fields are only applicable if "search in docstrings" is enabled.

- Fuzzy matches. The following search matches all documents that have a word within 1 edit distance of “foo”: `foo~1`

UNIX Process management.

Do NOT use this module directly - use reactor.spawnProcess() instead.

Maintainer: Itamar Shtull-Trauring

Class | `Process` | An operating-system Process.
Class | `ProcessReader` | ProcessReader
Class | `ProcessWriter` | (Internal) Helper class to write into a Process's input pipe.
Class | `PTYProcess` | An operating-system Process that uses PTY support.
Function | `reapAllProcesses` | Reap all registered processes.
Function | `registerReapProcessHandler` | Register a process handler for the given pid, in case `reapAllProcesses` is called.
Function | `unregisterReapProcessHandler` | Unregister a process handler previously registered with `registerReapProcessHandler`.
Variable | `detector` | Undocumented
Variable | `reapProcessHandlers` | Undocumented
Class | `_BaseProcess` | Base class for Process and PTYProcess.
Class | `_FDDetector` | This class contains the logic necessary to decide which of the available system techniques should be used to detect the open file descriptors for the current process. The chosen technique gets monkey-patched into the _listOpenFDs method of this class so that the detection only needs to occur once.
Function | `_listOpenFDs` | Use the global detector object to figure out which FD implementation to use.

def reapAllProcesses(): (source)

Reap all registered processes.

def registerReapProcessHandler(pid, process): (source)

Register a process handler for the given pid, in case `reapAllProcesses` is called.

Parameters
pid | the pid of the process.
process | a process handler.

def unregisterReapProcessHandler(pid, process): (source)

Unregister a process handler previously registered with `registerReapProcessHandler`.
