#8 | 1371 | Craig Mcpheeters |
Integration from the jam mainline. Note, many of these are empty integrations, but I wanted to not leave any pending integrations into my branch. |

#6 | 1190 | Craig Mcpheeters | Oops, the list is 0 based | ||
#5 | 1189 | Craig Mcpheeters |
Integration of changes from my A|W work branch. Added a -d11 debug mode, which outputs information on fate changes Create jam variables to show job (-jn) information, such as the number of jobs requested, whether or not there is more than one job, and a list of the job slot numbers. These can be used in a variety of ways in supporting multi-job builds Added jobs slot expansion to the action blocks, the sequence !! is replaced by the job slot the action is running in. Modified the special shell handling to include unix. It used to be that on Unix, you could create an action block which exceeded the size that execvp() could handle (perhaps only when the DynamicCommandSize option is enabled.) On NT, all non-default shells are invoked through a intermediate file. This modification does the same for unix shells. Improved the -d+10 debug level, the dependency graph. It now shows the flags on the node as well (NOUPDATE, NOTFILE, etc.) Only issue the '...skipped' messages for nodes which would have been built |

#4 | 1023 | Craig Mcpheeters |
Integration from //guest/craig_mcpheeters/work/jam/src/... This return incorporates all of the Alias|Wavefront extensions to Jam, into an area which is a proper branch of the Jam mainline. An integration of these files into the Jam mainline will show all of the differences. There are several extensions to Jam in this return. Look at the new file Jamfile.config for an explanation of the extensions, and how to compile them into your own copy of Jam. If you want to build a copy of Jam with all of the extensions, do this: jam -sAllOptions=1 Read the config file for more info. The extensions range from minor output tweaks and simple fixes to more major things like a header cache, serialization of output from multiple jobs, dynamic command block sizing These are all offered without warranty, etc. |
