From c51f1e27f0e307a80a57a840b2337e3226b3c2be Mon Sep 17 00:00:00 2001 From: jsmall-nvidia Date: Tue, 16 Nov 2021 08:54:55 -0500 Subject: Support around JSON-RPC (#2014) * #include an absolute path didn't work - because paths were taken to always be relative. * Use 'Process' to communicate with an command line tool. * Remove slang-win-stream * Tidy up windows ProcessUtil. * First version of BufferedReadStream. * Windows working IPC for steams. * Test proxy count option. * Split Process/ProcessUtil. Process is platform dependant. ProcessUtil are functions that are platform independent. * First implementation of Unix Process interface. * Unix process compiles on cygwin. * Fix typo in unix process. * Separate unix pipe stream error of invalid access, from pipe availability. * Fix in standard line extraction. * Make fd non blocking. * Fix issues with Windows Process streams. * Added UnixPipe. * Some fixes around UnixPipeStream. * Make a unix stream closed explicit. * Hack to debug linux process/stream. * Revert to old linux pipe handling. * Pass executable path for unit tests. Split out CommandLine into own source. * Small improvements in process/command line. * Check process behavior with crash. * Make stderr and stdout unbuffered for crash testing. * Only turn disable buffering in crash test. * Disable crash test on CI. * Fix crash on clang/linux. * Enable crash test. Remove _appendBuffer as can use StreamUtil functionality. * Added inital processing for http headers. * Small improvements to HttpHeader. * First pass HTTPPacketConnection working on windows. * Enable other Process communication tests. * Update comments. * WIP JSON RPC. * Add terminate to Process. Made JSONRPC a Util. * Small tidy up around HTTPPacketConnection. * Improve process termination options.
