// This file contains constants used in the network source line server
// protocol.
// Brief protocol description:
//
// Requests are sent via UDP. All requests begin with a sequence number
// that is prepended to the response. The sequence number is opaque
// to the server, it is provided for client tracking of requests.
//
// In this file, request and response fields will be described as:
// <foo:N>, which should be read as "foo, an N byte unsigned integer
// in network byte order". Strings will be described as <foo:S>.
//
// A client request looks like:
// <seq:2><command:1><command data>
// Where <seq> is a sequence number as described above, <command>
// is one of the commands listed below, and <command data> is arbitrary
// data, defined per-command.
//
// A server response looks like:
// <seq:2><status:1><data>
// Where <seq> is the same sequence number from the request,
// <status> is one of the OK or ERROR values defined below,
// with OK signifying that the request was formatted properly and
// the response contains data, and ERROR signifying that the request
// was malformed in some way. <data> is arbitrary data, defined
// per-command below.
//
// Strings are sent as a 2-byte integer encoding the length, followed
// by <length> bytes.
//
// Valid Commands:
//==================================================
// <HAS:1><module name:S><debug file:S><debug identifier:S>
// example: <HAS><0x8>test.dll<0x8>test.pdb<0xA>0123456789
//
// Query whether the module with this filename and debug information
// has been previously loaded.
//
// Server Response:
// <loaded:1>
// Where <loaded> is one of MODULE_LOADED or MODULE_NOT_LOADED
//
//==================================================
// <LOAD:1><module name:S><debug file:S><debug identifier:S>
// example: <LOAD><0x8>test.dll<0x8>test.pdb<0xA>0123456789
//
// Request that the server find and load symbols for this module.
//
// Server Response:
// <result:1>
// Where <result> is one of:
// LOAD_NOT_FOUND
// - Symbols not found
// LOAD_INTERRUPT
// - Processing should be interrupted, symbols may be available later
// LOAD_FAIL
// - Found symbols, but failed to load them
// LOAD_OK
// - Found and loaded symbols successfully
//
//==================================================
// <GET:1><module name:S><debug file:S><debug identifier:S><module base address:8><instruction address:8>
// example: <GET><0x8>test.dll<0x8>test.pdb<0x9>0123456789<0x0000000000010000><0x0000000000011A2B>
//
// Look up source line info for this module, loaded at this base address,
// for the code at this instruction address.
//
// Server Response:
// <function:S><func_base:8><source_file:S><source_line:4><source_line_base:8>
// - As many fields as available are filled in. Fields that are not available
// will contain an empty string, or a zero for numeric values.
//==================================================
// <GETSTACKWIN:1><module name:S><debug file:S><debug identifier:S><module base address:8><instruction address:8>
// example: <GETSTACKWIN><0x8>test.dll<0x8>test.pdb<0x9>0123456789<0x0000000000010000><0x0000000000011A2B>
//
// Look up Windows stack frame info for this module, loaded at this base
// address, for the code at this instruction address.
//
// Server Response:
// <stack:S>
// The stack info is formatted as in the symbol file format, with
// "STACK " omitted, as documented at:
// http://code.google.com/p/google-breakpad/wiki/SymbolFiles
// If no Windows stack frame info is available, an empty string is returned.
//==================================================
// <GETSTACKCFI:1><module name:S><debug file:S><debug identifier:S><module base address:8><instruction address:8>
// example: <GETSTACKCFI><0x8>test.dll<0x8>test.pdb<0x9>0123456789<0x0000000000010000><0x0000000000011A2B>
