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!

When we reimplemented LLProcess on APR, necessitating APR's funny callback
mechanism to sense child-process status, every isRunning() or getStatus() call
called the APR poll function that calls ALL registered LLProcess callbacks. In
other words, every time any consumer called any LLProcess::isRunning() method,
all LLProcess callbacks were redundantly fired. Change that so that the single
APR poll function is called once per frame, courtesy of the "mainloop"
LLEventPump. Once per viewer frame should be well within the realtime duration
in which it's reasonable to expect child-process status to change.
In effect, this changes LLProcess's public API to introduce a dependency on
"mainloop" ticks. Add such ticks to llprocess_test.cpp as well.

Turns out that some (many?) wildcard LLManifest.path(wildcard) calls are "just
in case": sweep up any (e.g.) "*.tga" files there may be, but no problem if
there are none.
Change path() logic so it tries the next tree (source, artwork, build) if
either a specific (non-wildcard) filename doesn't exist, as now, OR if a
wildcard matches 0 files in the current tree. This continues to support "just
in case" wildcards, while permitting wildcards to work in the artwork and
build trees as well as the source tree.
Use a more specific exception than ManifestError for missing file. Only in
that case should we try the next tree. Any other ManifestError should
propagate.

viewer_manifest.py's Linux_i686Manifest class has contained directives to copy
library files with names like (e.g.) "libapr-1.so.0.4.2", which means that
every update to any such library requires messing with viewer_manifest.py.
But LLManifest.path() claims to support wildcards, and it's more robust to
specify "libapr-1.so*" instead.
Unfortunately LLManifest.path()'s wildcard support only used to work for files
in the source tree (vs. the artwork tree or the build tree). The logic in
path() tries each tree in turn, relying on an exception to make it try the
next tree. This exception was raised for a nonexistent specific filename --
but it never used to raise that exception for a wildcard matching 0 files.
Instead it would simply report "0 files" and proceed, producing an invalid
viewer install.
Raise that exception for a wildcard matching nothing. This forces path() to
consider the artwork tree and the build tree, permitting us to use wildcards
in library names.
Define an exception specific to LLManifest: ManifestException rather than the
generic Python RuntimeException. Make it a subclass of RuntimeException so any
existing callers expecting to catch RuntimeException will continue to work.

LLJob was vestigial code from before migrating Job Object support into APR.
Also add APR signal-name string to getStatusString() output.

Once again we've been bitten by comparison failure between "c:\somepath" and
"C:\somepath". Normalize paths in both Python helper scripts to make that
comparison more robust.

Apparently something in the Linux system header chain #defines a macro Status
as 'int'. That's just Bad in C++ land. It should at the very least be a
typedef! #undefining it in llprocess.h permits the viewer to build.

Include logic to engage Linden apr_procattr_autokill_set() extension: on
Windows, magic CreateProcess() flag must be pushed down into apr_proc_create()
level. When using an APR package without that extension, present
implementation should lock (e.g.) SLVoice.exe lifespan to viewer's on Windows
XP but probably won't on Windows 7: need magic flag on CreateProcess().
Using APR child-termination callback requires us to define state (e.g.
LLProcess::RUNNING). Take the opportunity to present Status, capturing state
and (if terminated) rc or signal number; but since most of the time all caller
really wants is to log the outcome, also present status string, encapsulating
logic to examine state and describe exited-with-rc vs. killed-by-signal.
New Status logic may report clearer results in the case of a Windows child
process killed by exception.
Clarify that static LLProcess::isRunning(handle) overload is only for use when
the original LLProcess object has been destroyed: really only for unit tests.
We necessarily retain our original platform-specific implementations for just
that one method. (Nonstatic isRunning() no longer calls static method.)
Clarify log output from llprocess_test.cpp in a couple places.

Any RAII class should either be noncopyable or should deal appropriately with
a copy operation. ManageAPR is intended only for extremely simple cases, and
hence should be noncopyable.

TeamCity requires that certain characters (notably "'") must be escaped when
embedded in service messages:
http://confluence.jetbrains.net/display/TCD65/Build+Script+Interaction+with+TeamCity#BuildScriptInteractionwithTeamCity-ServiceMessages
TUT frequently outputs messages containing "'", e.g. from ensure_equals()
failure. We've seen TC output nesting get confused when it fails to process
service messages properly due to parsing unescaped messages.
Along with test<n> number, report test name (from set_test_name()) when
available.
Eliminate horsing around to produce normal output on both std::cout and
possible output file. When output file is specified, use
boost::iostreams::tee_device to do fanout for us.
Improve placement (and possibly reliability) of service messages.
Clean up a startling amount of redundancy in service-message production.

Use the new "Avatar Rez" debugging tag to see the output.

Windows 7 and friends tend to create a process already implicitly allocated to
a job object, and a process can only belong to a single job object. Passing
CREATE_BREAKAWAY_FROM_JOB in CreateProcessA()'s dwCreationFlags seems to
bypass the access-denied error observed with AssignProcessToJobObject()
otherwise.
This change should (!) enable OS lifespan management for SLVoice.exe et al.

On Posix, these and the corresponding getProcessID()/getProcessHandle()
accessors produce the same pid_t value; but on Windows, it's useful to
distinguish an int-like 'id' useful to human log readers versus an opaque
'handle' for passing to platform-specific API functions. So make the
distinction in a platform-independent way.

On Posix platforms, the OS argument mechanism makes quoting/reparsing
unnecessary anyway, so this only affects Windows.
Add optional 'triggers' parameter to LLStringUtils::quote() (default: space
and double-quote). Only if the passed string contains a character in
'triggers' will it be double-quoted.
This is observed to fix a Windows-specific problem in which plugin child
process would fail to start because it wasn't expecting a quoted number.
Use LLStringUtils::quote() more consistently in LLProcess implementation for
logging.
