# | Change | User | Description | Committed | |
---|---|---|---|---|---|
#6 | 9896 | Perforce staff |
Maximum command line length now determined by execmax() function, which still just returns the compiled-in MAXLINE. p4transfer.py: Transferred from production |
||
#5 | 3065 | Perforce staff |
Support for 'actions ... maxline value', to set a command specific maxline (rather than the OS-specific maximum). Undocumented. |

#4 | 2493 | rmg |
Rewrite the past: update all jam's source with comments to reflect changes since about 2.3, very early 2001. Whitespace only change. === computer:1666: Change 37660 by seiwald@play-seiwald on 2002/11/06 22:41:35 Note: I regenerated jamgram.c on my linux 7.3 system prior to the submit, since patch was so unhappy trying to lay down the changes from Christopher's change. Presumably this is just due to different yacc/bison/whatever particulars on the system where Christopher made the changes originally. - rmg |

#3 | 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. |
||

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) |
