Build rules for jam on Darwin 9.0. p4transfer.py: Transferred from production |
||
#14 | 9913 | Perforce staff |
Use off_t instead of long for lseek(), as cygwin seems to get confused if you use a long. Bug fix documented in RELNOTES. p4transfer.py: Transferred from production |
||
#13 | 9912 | tony |
jam and 2004.2 p4 client for AS/400. Built on AS/400 V5R2 with native ILE C/C++ compiler. Note, this build reports itself as P4/AS400/2004.2/76944 but this change contains porting changes that were required to make the build work so the changelist number is incorrect. This can be resolved with a clean build for 2005.1 at a later date. p4.sav and jam.sav are AS/400 "Save Files" that can be used to install the software on an AS/400 machine. The p4.sav file includes the p4.cmd and p4sync.cmd files we distributed with our older AS/400 builds. These files define a forms-type interface for supplying the parameters to the commands when you run them. Porting change only. No functional change. p4transfer.py: Transferred from production |

#12 | 9910 | tony |
Port Jam to Zeta. Zeta is a fork of BeOS so this port is broadly the same as the BeOS port. p4transfer.py: Transferred from production |
||
#11 | 2612 | rmg |
Fix three uninitialized memory reads: 1. var_expand() wasn't checking its input length when testing for the "$(<)" shortcut. 2. Solaris does a strlen() of its sscanf() input, and ar_hdr wasn't terminated. 3. Solaris archive entries / and //xxx (the string table) generated calls to time_enter() with an uninitialized file name. Bug fixes documented in RELNOTES. === computer:1666: Change 39713 by seiwald@play-seiwald on 2003/01/02 14:46:07 |

Big AIX archive support. Untested. Bug fix documented in RELNOTES. === computer:1666: Change 39590 by seiwald@play-seiwald on 2002/12/27 16:40:07 |

#9 | 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 |

#8 | 2491 | rmg |
Some consting in jam to make it more compilable by C++ compilers. No functional change. === computer:1666: Change 37433 by perforce@perforce on 2002/10/30 16:08:51 Recreational const-ing of jam, for compilers that don't allow "string" to be passed as a non-const char *. This included a few places where we were modifying what could possibly have been read-only storage, oddly enough. No functional change. === computer:1666: Change 37602 by seiwald@play-seiwald on 2002/11/04 17:25:40 |

#7 | 2483 | rmg |
Jam macosx changes: use 'ar' instead of libtool, as ar can do incremental updates. New support for the BSD style long filenames in archives. Porting change. === computer:1666: Change 34993 by seiwald@oswald-seiwald on 2002/07/16 12:01:32 Fix archive scan (solaris and FreeBSD style) broken by change #34993. I _think_ all three forms of archive entries now work again (traditional, solaris string table, and macosx #1/xxxx ). === computer:1666: Change 35027 by seiwald@play-seiwald on 2002/07/17 11:31:20 Fix archive scan supposedly fixed in 35027 (which was to fix 34993). Now it works on MacOSX again. === computer:1666: Change 35057 by perforce@cardtrick on 2002/07/17 16:11:01 |

Jam 2.3 + Perforce's internal changes. This change is a drop of the Perforce internal Jam changes since the 2.3 public release. The individual changes represented herein are preserved in the //guest/richard_geiger/intjam/ branch. The intent of this drop is to provide a base, from which other contributors' Jam branches may be integrated into. It is not intended to become a packaged release in this state. We will be integrating changes from other users prior to creating the next packaged release. Please refer to the src/RELNOTES file for an overview of the changes present in this integration. - Richard Geiger Open Source Engineer at Perforce |
