# | Change | User | Description | Committed | |
---|---|---|---|---|---|
#20 | 4338 | Matt Armstrong |
Now jam will read the default -j argument from the JAM_JOBS environment variable. |
||
#19 | 4337 | Matt Armstrong | New -dM build flag to get make1.c debug logging. | ||
#18 | 4080 | Matt Armstrong | j -v will print whether the .exe is a debug version or not | ||
#17 | 3969 | Matt Armstrong |
Integrate from //guest/matt_armstrong/jam/fix/2/...@3963 -- no real changes. |
||
#16 | 3950 | Matt Armstrong |
Integrate from //guest/matt_armstrong/jam/fix/1/... thru change 3948 and make no changes. |
||
#15 | 3665 | Matt Armstrong |
Fix debug statement logging. Under NT, don't compile debug versions by default. |
||
#14 | 3656 | Matt Armstrong |
Partial support for a -T flag that prints out more detailed memory usage statistics. |
||
#13 | 3628 | Matt Armstrong | Add an MD5 function to Jam. | ||
#12 | 3623 | Matt Armstrong | Left over crap from a previous install. | ||
#11 | 3622 | Matt Armstrong |
Append the features present in this Jam to the PATCHED_JAM_VERSION variable. |
||
#10 | 3516 | Matt Armstrong |
Steal OPT_INTERRUPT_FIX and re-steal OPT_GRAPH_DEBUG_EXT from Craig. |
||
#9 | 3447 | Matt Armstrong |
With OPT_PRINT_TOTAL_TIME_EXT, setting the JAM_ELAPSED_LOGFILE environment variable to a filename will cause build times to be written to that log file. |
||
#8 | 3327 | Matt Armstrong |
Patchlevel a.c. Remove OPT_IMPROVE_TEMP_FILE_DELETE_EXT since upstream has a fix. Implement OPT_FIX_NT_ARSCAN_LEAK to fix a memory leak in the NT arscan functions. Get Pure builds running on NT. |
||
#7 | 3318 | Matt Armstrong | Provide a check_leaks() function in PURE builds. | ||
#6 | 2817 | Matt Armstrong | Update with current known working version. | ||
#5 | 2507 | Matt Armstrong | update from the mainline | ||
#4 | 2089 | Matt Armstrong | More integrations from upstream. | ||
#3 | 2087 | Matt Armstrong | I think most of this is updates from stock jam. | ||
#2 | 1271 | Matt Armstrong |
This is "my" custom version of Jam. See the LOCAL_DIFFERENCES.txt file for a description of differences from the upstream jam. |
||
#1 | 1270 | Matt Armstrong | In prep for publishing all my patches to jam. | ||
//guest/perforce_software/jam/src/jam.c | |||||
#7 | 486 | Perforce staff |
Jam 2.3. See RELNOTES for a list of changes from 2.2.x. Just about every source file was touched when jam got ANSI-fied. |
||
#6 | 213 | Perforce staff | Peter Glasscock's MPW port. | ||
#5 | 212 | Perforce staff |
An interpretative integration of Peter Glasscock's -o file support. This is handled in the make1() routine, rather than in all the exec*.c files. -o x writes the actions to file x rather than actually running them. Implies -n (but not -d2). |
||
#4 | 76 | Laura Wingerd |
Integrate command-block-too-long fix, plus minor doc updates. Jam/MR release level is now 2.2.5. (change 72, change 73, change 74, change 75) |
||
#3 | 5 | Perforce maintenance | Jam/MR 2.2.4 (HDRPATTERN, JAMUNAME, JAMSHELL, plus misc tweaks) | ||
#2 | 3 | Perforce maintenance | Jam/MR 2.2.1 (fix for NT handle leak) | ||
#1 | 2 | laura | Add Jam/MR 2.2 source |
