+// 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>
