If caller runs (e.g.) a Python script, it's not very helpful to a human log
reader to keep seeing LLProcess instances logged as /pathname/to/python (pid).
If caller is aware, the code can at least use the script name as the desc --
or maybe even a hint as to the script's purpose.
If caller doesn't explicitly pass a desc, at least shorten to just the
basename of the executable.

This way a caller need not spin on isRunning(); we can just listen for the
requested termination event.
Post a similar event containing error message if for any reason
LLProcess::create() failed to launch the child.
Add unit tests for both cases.

That is, trying to instantiate a ReadPipeImpl while another already existed
would throw an LLEventPump::DupPumpName exception. Fortunately this behavior
is easily bypassed.

The typos didn't make for invalid tests, but they made a few tests redundant
while leaving other (subtly different) cases untested.

Add unit tests for peek() with substring args, reimplemented contains(),
various forms of find().
(yay unit tests)
|
|
|
|
If it's useful to have contains() to tell you whether incoming data contains a
particular substring, and if it's useful for contains() and peek() to accept
an offset within that data, then it's useful to allow you to get the offset of
a desired substring within that data. But of course a find() returning offset
needs something like std::string::npos for "not found"; borrow that
convention.
Support both find(const std::string&) and find(char); the latter permits a
more efficient implementation. In fact, make find(string) recognize a string
of length 1 and leverage the find(char) implementation.
Given that, reimplement contains(mumble) as shorthand for find(mumble) != npos.
Implement find() overloads using std::search() and std::find() on
boost::asio::streambuf character iterators, rather than copying to std::string
and then using string search like previous contains() implementation.
Reimplement WritePipeImpl::tick() and ReadPipeImpl::tick() to write/read
directly from/to boost::asio::streambuf data, instead of copying to/from a
temporary flat buffer.
As long as ReadPipeImpl::tick() keeps successfully filling buffers, keep
reading. Previous implementation would only handle a long child write over
successive tick() calls. Stop on read error or when we come up short.

These are all very well when we just want to dump the output to a log, or
whatever, but in a unit-test context it matters for comparison.

Also add "len" key to event data on LLProcess::getPump(). If you've used
setLimit(), event["data"].length() may not reflect the length of the
accumulated data in the ReadPipe.
Add unit test with stdin/stdout handshake with child process.

In the course of re-enabling the indra/test tests last year, Log generalized a
workaround I'd introduced in llsdmessage_test.cpp. In Linux viewer land, a
test program trying to catch an expected exception can't seem to catch it by
its specific class (across the libllcommon.so boundary), but must instead
catch std::runtime_error and validate the typeid().name() string. Log added a
macro for this idiom in llevents_tut.cpp. Generalize that macro further for
normal-case processing as well, move it to a header file of its own and use it
in all known places -- plus the new exception-catching tests in
llprocess_test.cpp.

Add LLProcess::FileParam to specify how to construct each child's standard
file slot, with lots of comments about features designed but not yet
implemented. The point is to design it with enough flexibility to be able to
extend to foreseeable use cases.
Add LLProcess::Params::files to collect up to 3 FileParam items. Naturally
this extends the accepted LLSD syntax as well.
Implement type="" (child inherits parent file descriptor) and "pipe" (parent
constructs anonymous pipe to pass to child).
Add LLProcess::FILESLOT enum, plus methods:
getReadPipe(FILESLOT), getOptReadPipe(FILESLOT)
getWritePipe(), getOptWritePipe()
getPipeName(FILESLOT): placeholder implementation for now
Add LLProcess::ReadPipe and WritePipe classes, as returned by get*Pipe().
WritePipe supports get_ostream() method for streaming to child stdin.
ReadPipe supports get_istream() method for reading from child stdout/stderr.
It also provides getPump() returning LLEventPump& so interested parties can
listen for arrival of new data on the aforementioned std::istream.
For "pipe" slots, instantiate appropriate *Pipe class.
ReadPipe and WritePipe classes are pure virtual bases for ReadPipeImpl and
WritePipeImpl, respectively: all implementation data are hidden in the latter
classes, visible only in llprocess.cpp. In fact each *PipeImpl class registers
itself for "mainloop" ticks, attempting nonblocking I/O to the underlying
apr_file_t on each tick. Data are buffered in a boost::asio::streambuf, which
bridges between std::[io]stream and the APR I/O calls.
Sanity-test ReadPipeImpl by using a pipe to absorb the Python "SyntaxError"
output from the successful syntax_error test, rather than alarming the user.
Add first few unit tests for validating FileParam. More tests coming!
