Comment (by jessicah):
I've finally been able to reliably reproduce the issue without resorting
to parallel jam. I think we might need an extra unique target for build
feature attributes, perhaps?
`jam -aq -d4 '<extracted-x86_gcc2:libwebp-devel>develop/headers/webp'`
{{{
Chmod1
/home/jessica/develop/gcc2h/generated/objects/linux/x86_64/release/tools/package/package
ExtractHPKGArchive1
/home/jessica/develop/gcc2h/generated/build_packages/libwebp-0.4.1-1-x86_gcc2
ExtractHPKGArchive1
/home/jessica/develop/gcc2h/generated/build_packages/libwebp-0.4.1-1-x86_gcc2
...updated 260 target(s)...
}}}
This creates the `build_packages/libwebp` directory and extracts a bunch
of build features. Now let's simulate parallel jam by removing the develop
headers sub-directory and jamming again.
`rm -rf generated/build_packages/libwebp*/develop`
`jam -aq -d4 '<extracted-x86_gcc2:libwebp-devel>develop/headers/webp'`
{{{
Chmod1
/home/jessica/develop/gcc2h/generated/objects/linux/x86_64/release/tools/package/package
...updated 258 target(s)...
}}}
Notice how with this invocation, that `ExtractHPKGArchive1` is never
invoked, and that `generated/build_packages/libwebp*/develop` doesn't
exist.
Attached are the before and after logs from jam using -d4 for debugging.
