| michael@0 | 4 | Environment Variables Impacting the Build System |
| michael@0 | 5 | ================================================ |
| michael@0 | 6 | |
| michael@0 | 7 | Various environment variables have an impact on the behavior of the |
| michael@0 | 8 | build system. This document attempts to document them. |
| michael@0 | 9 | |
| michael@0 | 10 | AUTOCLOBBER |
| michael@0 | 11 | If defines, the build system will automatically clobber as needed. |
| michael@0 | 12 | The default behavior is to print a message and error out when a |
| michael@0 | 13 | clobber is needed. |
| michael@0 | 14 | |
| michael@0 | 15 | This variable is typically defined in a :ref:`mozconfig <mozconfig>` |
| michael@0 | 16 | file via ``mk_add_options``. |
| michael@0 | 17 | |
| michael@0 | 18 | REBUILD_CHECK |
| michael@0 | 19 | If defined, the build system will print information about why |
| michael@0 | 20 | certain files were rebuilt. |
| michael@0 | 21 | |
| michael@0 | 22 | This feature is disabled by default because it makes the build slower. |
| michael@0 | 23 | |
| michael@0 | 24 | MACH_NO_TERMINAL_FOOTER |
| michael@0 | 25 | If defined, the terminal footer displayed when building with mach in |
| michael@0 | 26 | a TTY is disabled. |
| michael@0 | 27 | |
| michael@0 | 28 | MACH_NO_WRITE_TIMES |
| michael@0 | 29 | If defined, mach commands will not prefix output lines with the |
| michael@0 | 30 | elapsed time since program start. This option is equivalent to |
| michael@0 | 31 | passing ``--log-no-times`` to mach. |
| michael@0 | 32 | |
| michael@0 | 33 | MOZ_PSEUDO_DERECURSE |
| michael@0 | 34 | Activate an *experimental* build mode where make directory traversal |
| michael@0 | 35 | is derecursified. This mode should result in faster build times at |
| michael@0 | 36 | the expense of busted builds from time-to-time. The end goal is for |
| michael@0 | 37 | this build mode to be the default. At which time, this variable will |
| michael@0 | 38 | likely go away. |
| michael@0 | 39 | |
| michael@0 | 40 | A value of ``1`` activates the mode with full optimizations. |
| michael@0 | 41 | |
| michael@0 | 42 | A value of ``no-parallel-export`` activates the mode without |
| michael@0 | 43 | optimizations to the *export* tier, which are known to be slightly |
| michael@0 | 44 | buggy. |
| michael@0 | 45 | |
| michael@0 | 46 | A value of ``no-skip`` activates the mode without optimizations to skip |
| michael@0 | 47 | some directories during traversal. |
| michael@0 | 48 | |
| michael@0 | 49 | Values may be combined with a comma. |
