|
|---|
| 12686 | *
|
|---|
| 12687 | * The kSubmit / kWorker combo was conceived as a way to speed up VirtualBox
|
|---|
| 12688 | * builds on machines "infested" by Anti Virus protection and disk encryption
|
|---|
| 12689 | * software. Build times jumping from 35-40 min to 77-82 min after the machine
|
|---|
| 12690 | * got "infected".
|
|---|
| 12691 | *
|
|---|
| 12692 | * Speeing up builting of Boot Sector Kit \#3 was also hightly desirable. It is
|
|---|
| 12693 | * mainly a bunch of tiny assembly and C files being compiler a million times.
|
|---|
| 12694 | * As some of us OS/2 users maybe recalls, the Watcom make program can run its
|
|---|
| 12695 | * own toolchain from within the same process, saving a lot of process creation
|
|---|
| 12696 | * and teardown overhead.

| 12699 | * @section sec_kWorker_kSubmit About kSubmit
|
|---|
| 12700 | *
|
|---|
| 12701 | * When wanting to execute a job in a kWorker instance, it must be submitted
|
|---|
| 12702 | * using the kmk_builtin_kSubmit command in kmk. As the name suggest, this is
|
|---|
| 12703 | * built into kmk and does not exist as an external program. The reason for
|
|---|
| 12704 | * this is that it keep track of the kWorker instances.
|
|---|
| 12705 | *
|
|---|
| 12706 | * The kSubmit command has the --32-bit and --64-bit options for selecting
|
|---|
| 12707 | * between 32-bit and 64-bit worker instance. We generally assume the user of
|
|---|
| 12708 | * the command knows which bit count the executable has, so kSubmit is spared
|
|---|
| 12709 | * the extra work of finding out.
|
|---|
| 12710 | *
|
|---|
| 12711 | * The kSubmit command shares a environment and current directory manipulation
|
|---|
| 12712 | * with the kRedirect command, but not the file redirection. So long no file
|
|---|
| 12713 | * operation is involed, kSubmit is a drop in kRedirect replacement. This is
|
|---|
| 12714 | * hand for tools like OpenWatcom, NASM and YASM which all require environment
|
|---|
| 12715 | * and/or current directory changes to work.
|
|---|
| 12716 | *
|
|---|
| 12717 | * Unlike the kRedirect command, the kSubmit command can also specify an
|
|---|
| 12718 | * internall post command to be executed after the main command succeeds.
|
|---|
| 12719 | * Currently only kmk_builtin_kDepObj is supported. kDepObj gathers dependency
|
|---|
| 12720 | * information from Microsoft COFF object files and Watcom OMF object files and
|
|---|
| 12721 | * is scheduled to replace kDepIDB.

|
|---|
| 12725 | *
|
|---|
| 12726 | * The kmk_builtin_kSubmit communicates with the kWorker instances over pipes.
|
|---|
| 12727 | * A job request is written by kSubmit and kWorker read, unpacks it and executes
|
|---|
| 12728 | * it. When the job is completed, kWorker writes a short reply with the exit
|
|---|
| 12729 | * code and an internal status indicating whether it is going to restart.
|
|---|
| 12730 | *
|
|---|
| 12731 | * The kWorker intance will reply to kSubmit before completing all the internal
|
|---|
| 12732 | * cleanup work, so as not to delay the next job execution unnecessarily. This
|
|---|
| 12733 | * includes checking its own memory consumption and checking whether it needs
|
|---|
| 12734 | * restarting. So, a decision to restart unfortunately have to wait till after
|
|---|
| 12735 | * the next job has completed. This is a little bit unfortunate if the next job
|
|---|
| 12736 | * requires a lot of memory and kWorker has already leaked/used a lot.

| 12739 | * @section sec_kWorker_How_Works How kWorker Works
|
|---|
| 12740 | *
|
|---|
| 12741 | * kWorker will load the executable specified by kSubmit into memory and call
|
|---|
| 12742 | * it's entrypoint in a lightly sandbox'ed environment.
|

|
|---|
| 12745 | * @subsection ssec_kWorker_Loaing Image loading
|
|---|
| 12746 | *
|
|---|
| 12747 | * kWorker will manually load all the executable images into memory, fix them
|
|---|
| 12748 | * up, and make a copy of the virgin image so it can be restored using memcpy
|
|---|
| 12749 | * the next time it is used.
|
|---|
| 12750 | *
|
|---|
| 12751 | * Imported functions are monitored and replacements used for a few of them.
|
|---|
| 12752 | * These replacements are serve the following purposes:
|
|---|
| 12753 | * - Provide a different command line.
|
|---|
| 12754 | * - Provide a different environment.
|
|---|
| 12755 | * - Intercept process termination.
|
|---|
| 12756 | * - Intercept thread creation (only linker is allowed to create threads).
|
|---|
| 12757 | * - Intercept file reading for caching (header files, ++) as file system
|
|---|
| 12758 | * access is made even slower by anti-virus software.
|
|---|
| 12759 | * - Intercept crypto hash APIs to cache MD5 digests of header files
|
|---|
| 12760 | * (c1.dll / c1xx.dll spends a noticable bit of time doing MD5).
|
|---|
| 12761 | * - Intercept temporary files (%TEMP%/_CL_XXXXXXyy) to keep the entirely
|
|---|
| 12762 | * in memory as writing files grows expensive with encryption and
|
|---|
| 12763 | * anti-virus software active.
|
|---|
| 12764 | * - Intercept some file system queries to use the kFsCache instead of
|
|---|
| 12765 | * going to the kernel and slowly worm thru the AV filter driver.
|
|---|
| 12766 | * - Intercept standard output/error and console writes to aggressivly
|
|---|
| 12767 | * buffer the output. The MS CRT does not buffer either when it goes to
|
|---|
| 12768 | * the console, resulting in terrible performance and mixing up output
|
|---|
| 12769 | * with other compile jobs.
|
|---|
| 12770 | * This also allows us to filter out the annoying source file announcements
|
|---|
| 12771 | * by cl.exe.
|
|---|
| 12772 | * - Intercept VirtualAlloc and VirtualFree to prevent
|
|---|
| 12773 | * CL.EXE/C1.DLL/C1XX.DLL from leaking some 72MB internal allocat area.
|
|---|
| 12774 | * - Intercept FlsAlloc/FlsFree to make sure the allocations are freed and
|
|---|
| 12775 | * the callbacks run after each job.
|
|---|
| 12776 | * - Intercept HeapCreate/HeapFree to reduce leaks from statically linked
|
|---|
| 12777 | * executables and tools using custom heaps (like the microsoft linker).
|
|---|
| 12778 | * [exectuable images only]
|
|---|
| 12779 | * - Intercept atexit and _onexit registration to be able run them after
|
|---|
| 12780 | * each job instead of crashing as kWorker exits. This also helps avoid
|
|---|
| 12781 | * some leaks. [executable image only]
|
|---|
| 12782 | *
|
|---|
| 12783 | * DLLs falls into two categories, system DLLs which we always load using the
|
|---|
| 12784 | * native loader, and tool DLLs which can be handled like the executable or
|
|---|
| 12785 | * optionally using the native loader. We maintain a hardcoded white listing of
|
|---|
| 12786 | * tool DLLs we trust to load using the native loader.
|
|---|
| 12787 | *
|
|---|
| 12788 | * Imports of natively loaded DLLs are processed too, but we only replace a
|
|---|
| 12789 | * subset of the functions compared to natively loaded excutable and DLL images.
|
|---|
| 12790 | *
|
|---|
| 12791 | * DLLs are never unloaded and we cache LoadLibrary requests (hash the input).
|
|---|
| 12792 | * This is to speed up job execution.
|
|---|
| 12793 | *
|
|---|
| 12794 | * It was thought that we needed to restore (memcpy) natively loaded tool DLLs
|
|---|
| 12795 | * for each job run, but so far this hasn't been necessary.

|
|---|
| 12799 | *
|
|---|
| 12800 | * The Visual Studio 2010 C/C++ compiler does a poor job at processing header
|
|---|
| 12801 | * files and uses a whole bunch of temporary files (in %TEMP%) for passing
|
|---|
| 12802 | * intermediate representation between the first (c1/c1xx.dll) and second pass
|
|---|
| 12803 | * (c2.dll).
|
|---|
| 12804 | *
|
|---|
| 12805 | * kWorker helps the compiler as best as it can. Given a little knowledge about
|
|---|
| 12806 | * stable and volatile file system areas, it can do a lot of caching that a
|
|---|
| 12807 | * normal compiler driver cannot easily do when given a single file.
|
|---|
| 12808 | *
|

| 12809 | *
|
|---|
| 12810 | * @subsubsection sssec_kWorker_Headers Cache Headers Files and Searches
|
|---|
| 12811 | *
|
|---|
| 12812 | * The preprocessor part will open and process header files exactly as they are
|
|---|
| 12813 | * encountered in the source files. If string.h is included by the main source
|
|---|
| 12814 | * and five other header files, it will be searched for (include path), opened,
|
|---|
| 12815 | * read, MD5-summed, and pre-processed six times. The last five times is just a
|
|---|
| 12816 | * waste of time because of the guards or \#pragma once. A smart compiler would
|
|---|
| 12817 | * make a little extra effort and realize this.
|
|---|
| 12818 | *
|
|---|
| 12819 | * kWorker will cache help the preprocessor by remembering places where the
|
|---|
| 12820 | * header was not found with help of kFsCache, and cache the file in memory when
|
|---|
| 12821 | * found. The first part is taken care of by intercepting GetFileAttributesW,
|
|---|
| 12822 | * and the latter by intercepting CreateFileW, ReadFile and CloseFile. Once
|
|---|
| 12823 | * cached, the file is kept open and the CreateFileW call returns a duplicate of
|
|---|
| 12824 | * that handle. An internal handle table is used by ReadFile and CloseFile to
|
|---|
| 12825 | * keep track of intercepted handles (also used for temporary file, temporary
|
|---|
| 12826 | * file mappings, console buffering, and standard out/err buffering).
|
|---|
| 12827 | *
|
|---|
| 12828 | * PS. The header search optimization also comes in handy when cl.exe goes on
|
|---|
| 12829 | * thru the whole PATH looking for c1/c1xx.exe and c2.exe after finding
|
|---|
| 12830 | * c1/c1xx.dll and c2.dll. My guess is that the compiler team can
|
|---|
| 12831 | * optionally compile the three pass DLLs as executables during development
|
|---|
| 12832 | * and problem analysis.

|
|---|
| 12835 | * @subsubsection sssec_kWorker_Temp_Files Temporary Files In Memory
|
|---|
| 12836 | *
|
|---|
| 12837 | * The issues of the temporary files is pretty severe on the Dell machine used
|
|---|
| 12838 | * for benchmarking with full AV and encryption. The synthetic benchmark
|
|---|
| 12839 | * improved by 30% when kWorker implemented measures to keep them entirely in
|
|---|
| 12840 | * memory.
|
|---|
| 12841 | *
|
|---|
| 12842 | * kWorker implement these by recognizing the filename pattern in CreateFileW
|
|---|
| 12843 | * and creating/opening the given file as needed. The handle returned is a
|
|---|
| 12844 | * duplicate of the current process, thus giving us a good chance of catching
|
|---|
| 12845 | * API calls we're not intercepting.
|
|---|
| 12846 | *
|
|---|
| 12847 | * In addition to CreateFileW, we also need to intercept GetFileType, ReadFile,
|
|---|
| 12848 | * WriteFile, SetFilePointer+Ex, SetEndOfFile, and CloseFile. The 2nd pass
|
|---|
| 12849 | * additionally requires GetFileSize+Ex, CreateFileMappingW, MapViewOfFile and
|
|---|
| 12850 | * UnmapViewOfFile.
