UXP uses the current stack frame address and the stack size as a sort of heuristic for various things in the JavaScript engine. The js::GetNativeStackBaseImpl() function is used to get the base stack address (i.e. the address from which the stack grows, so this can be either the first or last memory address of the stack memory space depending on the CPU architecture). On Linux, this function is implemented using the pthreads APIs. For non-main threads, the queried thread info is stored in memory. The main thread does not have this information on hand, so it gets the stack memory range via the /proc/self/maps file (see glibc's pthread_get_attr_np.c). Fortunately (per discussions with the firefox devs in #jsapi) the base address only needs to be approximate. In reality, environment variables, args, and other things are stored in stack space between the end/beginning of the mapped stack memory and the 'top' of the stack space used by stack frames. When using glibc, we can get the top of this usable stack from __libc_stack_end, which is a void* set by glibc during program initialization, avoiding the need to access /proc. Non-main threads still get their stack-base through the usual pthreads APIs. Other libc implementations like musl will fall back to the standard UNIX-like implementation which calls pthread's pthread_attr_getstack() also from the main thread, which may imply /proc access and not work in restricted environments. |

Unified XUL Platform (UXP)
This repository holds the code for a unified application platform for XUL-based applications. It is a hard fork from the Mozilla code repository (mozilla-central) with an ESR-52 fork point.
In addition to further development based on the Mozilla upstream code, and selective cherry-picking of directly-applicable patches, this repository has its own development and holds the base for a future platform to be used by XUL applications.
This repository will contain at least one application to demonstrate and make use of the platform: The Basilisk web browser, a close twin to Mozilla's Firefox.
Additional documentation
Additional documentation relevant to this source code can be found in the /docs
directory. This will contain relevant documentation regarding contributing,
using and distributing this code and its binaries.

Foundation and maintainership
This repository has been founded and is maintained by Moonchild (M.C. Straver). If you fork this repository to perform your own work on it, please consider offering improvement patches upstream to its origin to mutually improve the platform and build a future for XUL.
