Each 39thread works on a single board at a time. It checks out the first commit, 40configures it for that board, then builds it. Then it checks out the next 41commit and builds it (typically without re-configuring). When it runs out 42of commits, it gets another job from the builder and starts again with that 43board. 44 45Clearly the builder threads could work either way - they could check out a 46commit and then built it for all boards. Using separate directories for each 47commit/board pair they could leave their build product around afterwards 48also. 49 50The intent behind building a single board for multiple commits, is to make 51use of incremental builds. Since each commit is built incrementally from 52the previous one, builds are faster. Reconfiguring for a different board 53removes all intermediate object files. 54 55Many threads can be working at once, but each has its own working directory. 56When a thread finishes a build, it puts the output files into a result 57directory. 58 59The base directory used by buildman is normally '../<branch>', i.e. 60a directory higher than the source repository and named after the branch 61being built. 62 63Within the base directory, we have one subdirectory for each commit. Within 64that is one subdirectory for each board. Within that is the build output for 65that commit/board combination. 66 67Buildman also create working directories for each thread, in a .bm-work/ 68subdirectory in the base dir. 69 70As an example, say we are building branch 'us-net' for boards 'sandbox' and 71'seaboard', and say that us-net has two commits. We will have directories 72like this: 73 74us-net/ base directory 75 01_of_02_g4ed4ebc_net--Add-tftp-speed-/ 76 sandbox/ 77 u-boot.bin 78 seaboard/ 79 u-boot.bin 80 02_of_02_g4ed4ebc_net--Check-tftp-comp/ 81 sandbox/ 82 u-boot.bin 83 seaboard/ 84 u-boot.bin 85 .bm-work/ 86 00/ working directory for thread 0 (contains source checkout) 87 build/ build output 88 01/ working directory for thread 1 89 build/ build output 90 ... 91u-boot/ source directory 92 .git/ repository 93""" 94 95# Possible build outcomes 96OUTCOME_OK, OUTCOME_WARNING, OUTCOME_ERROR, OUTCOME_UNKNOWN = range(4) 97 98# Translate a commit subject into a valid filename 99trans_valid_chars = string.maketrans("/: ", "---") 100 101CONFIG_FILENAMES = [ 102 '.config', '.config-spl', '.config-tpl', 103 'autoconf.mk', 'autoconf-spl.mk', 'autoconf-tpl.mk', 104 'autoconf.h', 'autoconf-spl.h','autoconf-tpl.h', 105 'u-boot.cfg', 'u-boot-spl.cfg', 'u-boot-tpl.cfg' 106] 107 108class Config: 109 """Holds information about configuration settings for a board.""" 110 def __init__(self, target): 111 self.target = target 112 self.config = {} 113 for fname in CONFIG_FILENAMES: 114 self.config[fname] = {} 115 116 def Add(self, fname, key, value): 117 self.config[fname][key] = value 118 119 def __hash__(self): 120 val = 0 121 for fname in self.config: 122 for key, value in self.config[fname].iteritems(): 123 print key, value 124 val = val ^ hash(key) & hash(value) 125 return val 126 127class Builder: 128 """Class for building U-Boot for a particular commit. 129 130 Public members: (many should ->private) 131 already_done: Number of builds already completed 132 base_dir: Base directory to use for builder 133 checkout: True to check out source, False to skip that step. 134 This is used for testing. 135 col: terminal.Color() object 136 count: Number of commits to build 137 do_make: Method to call to invoke Make 138 fail: Number of builds that failed due to error 139 force_build: Force building even if a build already exists 140 force_config_on_failure: If a commit fails for a board, disable 141 incremental building for the next commit we build for that 142 board, so that we will see all warnings/errors again. 143 force_build_failures: If a previously-built build (i.e. built on 144 a previous run of buildman) is marked as failed, rebuild it. 145 git_dir: Git directory containing source repository 146 last_line_len: Length of the last line we printed (used for erasing 147 it with new progress information) 148 num_jobs: Number of jobs to run at once (passed to make as -j) 149 num_threads: Number of builder threads to run 150 out_queue: Queue of results to process 151 re_make_err: Compiled regular expression for ignore_lines 152 queue: Queue of jobs to run 153 threads: List of active threads 154 toolchains: Toolchains object to use for building 155 upto: Current commit number we are building (0.count-1) 156 warned: Number of builds that produced at least one warning 157 force_reconfig: Reconfigure U-Boot on each comiit.
