This commit introduces no functional change. It only adds comments and
changes some function/variable names.

The following errors have been corrected:
* If primary archive was named "xxx", then a file in the same
directory named "xxxyyy" would be interpreted as a file named yyy
inside the archive.
* erl_prim_loader did not correctly create and normalize absolute
paths for primary archive and files inside it, so unless given with
exact same path files inside the archive would not be found. E.g. if
escript was started as /full/path/to/xxx then "./xxx/file" would not
be found since erl_prim_loader would try to match /full/path/to/xxx
with /full/path/to/./xxx. Same problem with ../.
* Depending on how the primary archive was built,
erl_prim_loader:list_dir/1 would sometimes return an empty string
inside the file list. This was a virtual element representing the
top directory of the archive. This has been removed.
Thanks to Tuncer Ayaz and Shunichi Shinohara for reporting and
co-authoring corrections.

If the mtime of an escript/primary archive file changes after being
added to the code path, correctly reload the archive and update the
cache.
The existing code didn't consider that it might be a zip archive and failed:
=ERROR REPORT==== 3-Aug-2011::09:21:21 ===
File operation error: bad_central_directory. Target:
/escript_archive/module.beam. Function: get_file. Process: code_server.
Thanks David Reid and Hakan Mattson.

erts/emulator/hipe/hipe_arm.c started out as a clone of hipe_ppc.c,
with #ifdefs to select ARM-specific code. Somehow those #ifdefs
never got cleaned out, resulting in fairly ugly-looking code.
This eliminates the #ifdefs, deletes dead PowerPC-specific code, and
keeps only the ARM-specific code. I've verified that the exact same
assembly code is generated for hipe_arm.c before and after this patch
(if you compile without -g, with -g there are unavoidable changes to
the debug data).

Bug introduced in R15.
|
|
|
|
Calls to erlang:set_trace_pattern/3 will no longer block all
other schedulers.
We will still go to single-scheduler mode when new code is loaded
for a module that is traced, or when loading code when there is a
default trace pattern set. That is not impossible to fix, but that
requires much closer cooperation between tracing BIFs and the loader
BIFs.
|
|
To allow us to manage breakpoints without going to single-scheduler
mode, we will need to update the breakpoints in several stages with
memory barriers in between each stage. Prepare for that by splitting
up the breakpoint setting and clearing functions into several smaller
functions.
|
|
Change the data structures for breakpoints to make it possible
(in a future commit) to manage breakpoints without taking down the
system to single-scheduling mode.
The current "breakpoint wheel" data structure (a circular,
double-linked list of breakpoints) was invented before the
SMP emulator. To support it in the SMP emulator, there is essentially
one breakpoint wheel per scheduler. As more breakpoint types have
been added, the implementation has become messy and hard to understand
and maintain.
Therefore, the time for a rewrite has come. Use one struct to hold
all breakpoint data for a breakpoint in a function. Use a flag field
to indicate what different type of break actions that are enabled.

Make sure that the the currently running thread has the lock,
not only that that some thread has the lock.

Fix faulty use of thread progress in handle_aux_work()

* rickard/thr-prgr-use/OTP-10116:
Fix faulty use of thread progress in handle_aux_work()
|
|
|
|
As an optimization old thread progress data was kept and used in
handle_aux_work() in erl_process.c. This could cause memory to be
deallocated at a later time than intended, which is quite harmless.
This has, however, now been fixed.
