llsd::array(), as one might suspect, takes an arbitrary number of arguments of
arbitrary convertible types and returns an LLSD::Array constructed from those
elements. This supercedes the older LLSDArray class.
llsd::map() takes an even number of arguments paired as (LLSD::String,
arbitrary convertible type) and returns an LLSD::Map constructed from those
(key, value) pairs. This supercedes the older LLSDMap class.
These two functions not only have a simpler API -- arbitrary function
arguments rather than an (arg list)(arg list) sequence -- but also
specifically return a final LLSD object, rather than needing conversion to
LLSD from the LLSDArray or LLSDMap object.
Also support LLSD == LLSD and LLSD != LLSD comparisons, using llsd_equals()
with default exact-float-equality semantics.

The comments within indra/test/test.cpp promise that --debug is, in fact, like
LOGTEST=DEBUG. Until now, that was a lie. LOGTEST=level displayed log output
on stderr as well as in testprogram.log, while --debug did not.
Add LLError::logToStderr() function, and make initForApplication() (i.e.
commonInit()) call that instead of instantiating RecordToStderr inline. Also
call it when test.cpp recognizes --debug switch.
Remove the mFileRecorder, mFixedBufferRecorder and mFileRecorderFileName
members from SettingsConfig. That tactic doesn't scale.
Instead, add findRecorder<RECORDER>() and removeRecorder<RECORDER>() template
functions to locate (or remove) a RecorderPtr to an object of the specified
subclass. Both are based on an underlying findRecorderPos<RECORDER>() template
function. Since we never expect to manage more than a handful of RecorderPtrs,
and since access to the deleted members is very much application setup rather
than any kind of ongoing access, a search loop suffices.
logToFile() uses removeRecorder<RecordToFile>() rather than removing
mFileRecorder (the only use of mFileRecorder).
logToFixedBuffer() uses removeRecorder<RecordToFixedBuffer>() rather than
removing mFixedBufferRecorder (the only use of mFixedBufferRecorder).
Make RecordToFile store the filename with which it was instantiated. Add a
getFilename() method to retrieve it. logFileName() is now based on
findRecorder<RecordToFile>() instead of mFileRecorderFileName (the only use of
mFileRecorderFileName).
Make RecordToStderr::mUseANSI a simple bool rather than a three-state enum,
and set it immediately on construction. Apparently the reason it was set
lazily was because it consults its own checkANSI() method, and of course
'this' doesn't acquire the leaf class type until the constructor has completed
successfully. But since nothing in checkANSI() depends on anything else in
RecordToStderr, making it static solves that problem.

Actually the fix is in postAndSuspendSetup(), which affects postAndSuspend(),
postAndSuspendWithTimeout(), suspendUntilEventOnWithTimeout() and
suspendUntilEventOn().
By "overflow case" we mean the special circumstance in which:
* the LLEventPump in question is an LLEventMailDrop, meaning its listeners
eventually expect to see every post()ed value
* one of the listeners is supposed to consume those values (has called
LLCoros::set_consuming(true))
* post() is called more than once before that listener is resumed.
The magic of postAndSuspend() (et al.) is a temporary LLCoros::Promise. The
waiting coroutine calls get() on the corresponding Future, causing it to
suspend (as promised) until the Promise is fulfilled.
With the Boost.Fiber implementation of coroutines, fulfilling the Promise
doesn't immediately resume the suspended coroutine -- it merely marks it ready
to resume, next time the scheduler gets control.
A second post() call before the suspended coroutine is resumed results in a
second call to Promise::set_value(). But Promise is a one-shot entity. This
results in a promise_already_satisfied exception. Because a second post() call
during that time window is perfectly reasonable, we catch that exception and
carry on.
The tricky part is: when that exception is thrown, what should the listener
return? Previously we were returning the listener's current consuming setting,
just as when the set_value() call succeeds.
But when the LLEventPump is an LLEventMailDrop, and the listener's consuming
flag is true, that told LLEventMailDrop::post() that the value got through,
and that it needn't bother to save it in its history queue. The net effect was
to discard the value.
Instead, return the listener's consuming flag only when Promise::set_value()
succeeds. When it throws promise_already_satisfied, unconditionally return
false. That directs LLEventMailDrop::post() to enqueue the undelivered value
so that the *next* suspendUntilEventOn() call can pick it up.

Use new Sync class to make the driving logic wait for the coprocedure to run.
|
|
Sync is specifically intended for test programs. It is based on an
LLScalarCond<int>. The idea is that each of two coroutines can watch for the
other to get a chance to run, indicated by incrementing the wrapped int and
notifying the wrapped condition_variable. This is less hand-wavy than calling
llcoro::suspend() and hoping that the other routine will have had a chance to
run.
Use Sync in lleventcoro_test.cpp.
Also refactor lleventcoro_test.cpp so that instead of a collection of static
data requiring a clear() call at start of each individual test function, the
relevant data is all part of the test_data struct common to all test
functions. Make the helper coroutine functions members of test_data too.
Introduce llcoro::logname(), a convenience function to log the name of the
currently executing coroutine or "main" if in the thread's main coroutine.

If the test<1>() child process terminates with nonzero rc, also report any
stdout/stderr it might have emitted first.
|
|
|
|
|
|
|
|
|
|
|
|
Also introduce value_type typedef.
|
|
LLCond encapsulates the usage patterns required to properly use
condition_variable. We also provide LLScalarCond, LLBoolCond and LLOneShotCond.

The global replace in changeset bd80903cf987 was a bit too sweeping: a comment
mentioning the OS function wait() (which exists) was inadvertently changed to
talk about an OS function suspend() (which does not).

For reasons not yet diagnosed, specifically in Mac Release builds, the tests
in test_httprequest.hpp consistently crash with a backtrace suggesting that
the worker thread is calling LLCore::HttpLibcurl::completeRequest() after the
foreground thread calls HttpRequest::destroyService().
Weirdly, even executing a tut::skip() call in every test<n>() function up to
the point of the crash does not eliminate the crash.

NickyD discovered that the substitute default allocator used for llcorehttp
tests was returning badly-aligned storage, which caused access violations on
alignment-sensitive data such as std::atomic. Thanks Nicky!!
Moreover, the llcorehttp test assertions regarding memory usage, well-
intentioned though they are, have been causing us trouble for years. Many have
already been disabled.
The problem is that use of test_allocator.h affected *everything* defined with
that header file's declarations visible. That inevitably included specific
functions in other subsystems. Those functions then (unintentionally) consumed
the special allocator, throwing off the memory tracking and making certain
memory-related assertions consistently fail.
This is a particular, observable bad effect of One Definition Rule violations.
Within a given program, C++ allows multiple definitions for the same entity,
but requires that all such definitions be the same. Partial visibility of the
global operator new() and operator delete() overrides meant that some
definitions of certain entities used the default global allocator, some used
llcorehttp's. There may have been other, more subtle bad effects of these ODR
violations.
If one wanted to reimplement verification of the memory consumption of
llcorehttp classes:
* Each llcorehttp class (for which memory tracking was desired) should declare
class-specific operator new() and operator delete() methods. Naturally,
these would all consume a central llcorehttp-specific allocator, but that
allocator should *not* be named global operator new().
* Presumably that would require runtime indirection to allow using the default
allocator in production while substituting the special allocator for tests.
* Recording and verifying the memory consumption in each test should be
performed in the test-object constructor and destructor, rather than being
sprinkled throughout the test<n>() methods.
* With that mechanism in place, the test object should provide methods to
adjust (or entirely disable) memory verification for a particular test.
* The test object should also provide a "yes, we're still consuming llcorehttp
memory" method to be used for spot checks in the middle of tests -- instead
of sprinkling in explicit comparisons as before.
* In fact, the llcorehttp test object in each test_*.hpp file should be
derived from a central llcorehttp test-object base class providing those
methods.

Hopefully this is temporary until we solve the problem of crashy llcorehttp
test executable on Mac.

Using boost::fibers::unbuffered_channel can block the mainthread when calling mPendingCoprocs.push (LLCoprocedurePool::enqueueCoprocedure)
From the documentation:
- If a fiber attempts to send a value through an unbuffered channel and no fiber is waiting to receive the value, the channel will block the sending fiber.
This can happen if LLCoprocedurePool::coprocedureInvokerCoro is running a coroutine and this coroutine calls yield, resuming the viewers main loop. If inside
the main loop someone calls LLCoprocedurePool::enqueueCoprocedure now push will block, as there's no one waiting for a result right now.
The wait would be in LLCoprocedurePool::coprocedureInvokerCoro at the start of the while loop, but we have not reached that yet again as LLCoprocedurePool::coprocedureInvokerCoro
did yield before reaching pop_wait_for.
The result is a deadlock.
boost::fibers::buffered_channel will not block as long as there's space in the channel. A size of 4096 (DEFAULT_QUEUE_SIZE) should be plenty enough for this.

On login failure, LLLogin now tries to sync up with SLVersionChecker. It waits
for up to 10 seconds before shrugging and giving up. Since that coroutine can
now block for that long, make the llogin_test failure cases wait at least that
long too.
