Convert build/docs/*.rst (top-level and mozbuild/) to MyST-flavored
Markdown.
- Keep build/docs/mozbuild-symbols.rst as RST. The mozbuildsymbols
custom directive emits nodes that confuse autosectionlabel when
wrapped in a MyST eval-rst block.
- Keep build/docs/supported-configurations.rst as RST so that
docs/contributing/build/supported.md can continue to use the MyST
{include} directive on the original source.
- Refresh allowed-warnings globs to match the .md filenames for
code-quality, contributing, crash-reporting, gtest, jsloader, js,
overview, setup, and js/build.

# Environment Variables Impacting the Build System
|
|
|
|
Various environment variables have an impact on the behavior of the
|
|
build system. This document attempts to document them.
|
|
|
|
AUTOCLOBBER
|
|
|
|
: If defines, the build system will automatically clobber as needed.
|
|
The default behavior is to print a message and error out when a
|
|
clobber is needed.
|
|
|
|
This variable is typically defined in a {ref}`mozconfig <mozconfig>`
|
|
file via `mk_add_options`.
|
|
|
|
REBUILD_CHECK
|
|
|
|
: If defined, the build system will print information about why
|
|
certain files were rebuilt.
|
|
|
|
This feature is disabled by default because it makes the build slower.
|
|
|
|
MACH_NO_TERMINAL_FOOTER
|
|
|
|
: If defined, the terminal footer displayed when building with mach in
|
|
a TTY is disabled.
|
|
|
|
MACH_NO_FUNC_CACHE
|
|
|
|
: If defined, disables mach's persistent function result cache. This
|
|
cache speeds up operations like configure by avoiding redundant
|
|
expensive computations when input files haven't changed.
|
|
|
|
MACH_NO_WRITE_TIMES
|
|
|
|
: If defined, mach commands will not prefix output lines with the
|
|
elapsed time since program start. This option is equivalent to
|
|
passing `--log-no-times` to mach.
