2021-12-10SL-15742: Convert build scripts to Python 3Bennett Goble
This changeset makes it possible to build the Second Life viewer using Python 3. It is designed to be used with an equivalent Autobuild branch so that a developer can compile without needing Python 2 on their machine. Breaking change: Python 2 support ending Rather than supporting two versions of Python, including one that was discontinued at the beginning of the year, this branch focuses on pouring future effort into Python 3 only. As a result, scripts do not need to be backwards compatible. This means that build environments, be they on personal computers and on build agents, need to have a compatible interpreter. Notes - SLVersionChecker will still use Python 2 on macOS - Fixed the message template url used by template_verifier.py

2020-03-25DRTVWR-476: Improve llprocess_test.cpp diagnostic output.Nat Goodspeed
If the test<1>() child process terminates with nonzero rc, also report any stdout/stderr it might have emitted first.
2019-08-10DRTVWR-493: Introduce test catch_what(), catch_llerrs() functions.Nat Goodspeed
Use them in place of awkward try/catch test boilerplate.
2018-12-14SL-10153: Review and rationalize fetching paths from environment.Nat Goodspeed
Use LLStringUtil::getenv() or getoptenv() whenever we fetch a string that will be used as a pathname. Use LLFile::tmpdir() instead of getenv("TEMP"). As an added extra-special bonus, finally clean up $TMP/llcontrol-test-zzzzzz directories that have been accumulating every time we run a local build!

2012-03-13Add timeout functionality to waitfor() helper functions.Nat Goodspeed
Otherwise, a stuck child process could potentially hang the test, and thus the whole viewer build.
2012-03-01Make CaptureLog::withMessage() raise tut::failure if not found.Nat Goodspeed
All known callers were using ensure(! withMessage(...).empty()). Centralize that logic. Make failure message report the string being sought and the log messages in which it wasn't found. In case someone does want to permit the search to fail, add an optional 'required' parameter, default true. Leverage new functionality in llprocess_test.cpp.
2012-03-01Break out TestRecorder class as CaptureLog into wrapllerrs.h.Nat Goodspeed
Giving more unit tests the ability to capture and examine log output is generally useful. Renaming the class just makes it less ambiguous: what's a TestRecorder? Something that records tests?
2012-02-29Guarantee LLProcess::Params::postend listener any ReadPipe data.Nat Goodspeed
Previously one might get process-terminated notification but still have to wait for the child process's final data to arrive on one or more ReadPipes. That required complex consumer timing logic to handle incomplete pending ReadPipe data, e.g. a partial last line with no terminating newline. New code guarantees that by the time LLProcess sends process-terminated notification, all pending pipe data will have been buffered in ReadPipes. Document LLProcess::ReadPipe::getPump() notification event; add "eof" key. Add LLProcess::ReadPipe::getline() and read() convenience methods. Add static LLProcess::getline() and basename() convenience methods, publishing logic already present elsewhere. Use ReadPipe::getline() and read() in unit tests. Add unit test for "eof" event on ReadPipe::getPump(). Add unit test verifying that final data have been buffered by termination notification event.
2012-02-27Reduce redundancy in llprocess_test.cpp using get_test_name().Nat Goodspeed
2012-02-23Tighten up LLProcess pipe support, per Richard's code review.Nat Goodspeed
Clarify wording in some of the doc comments; be a bit more explicit about some of the parameter fields. Make some query methods 'const'. Change default LLProcess::ReadPipe::getLimit() value to 0: don't post any incoming data with notification event unless caller requests it. But do post pertinent FILESLOT in case caller reuses same listener for both stdout and stderr. Use more idiomatic, readable syntax for accessing LLProcess::Params data.
2012-02-20Let LLProcess consumer specify desired description for logging.Nat Goodspeed
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.
2012-02-20Make LLProcess post termination event to specified pump if desired.Nat Goodspeed
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.
2012-02-16Fix typos in a few LLProcess::ReadPipe::find() unit tests.Nat Goodspeed
The typos didn't make for invalid tests, but they made a few tests redundant while leaving other (subtly different) cases untested.
2012-02-16Fix bug in LLProcess::ReadPipe::peek() substring computation.Nat Goodspeed
Add unit tests for peek() with substring args, reimplemented contains(), various forms of find(). (yay unit tests)
2012-02-16Add unit test for LLProcess::ReadPipe::setLimit().Nat Goodspeed
2012-02-16Add LLProcess::ReadPipe::find() methods, with corresponding npos.Nat Goodspeed
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.
2012-02-15Add unit test for listening on LLProcess::ReadPipe::getPump().Nat Goodspeed
2012-02-15Don't be confused by "\r\n" line endings on pipe on Windows.Nat Goodspeed
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.
2012-02-15Add LLProcess::ReadPipe::size(), peek(), contains().Nat Goodspeed
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.
2012-02-15Fix llprocess_test.cpp's exception catching for Linux.Nat Goodspeed
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.
2012-02-15Add tests for LLProcess::get[Opt][Read|Write]Pipe() validations.Nat Goodspeed
2012-02-15Preliminary pipe support for LLProcess.Nat Goodspeed
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!
2012-02-13Use per-frame ticks on "mainloop" LLEventPump to update LLProcess.Nat Goodspeed
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.
2012-02-13Add unit tests for LLProcess::Status functionality.Nat Goodspeed
2012-02-07Use os.path.normcase(os.path.normpath()) when comparing directories.Nat Goodspeed
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.
2012-02-07Convert LLProcess implementation from platform-specific to using APR.Nat Goodspeed
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.
2012-01-30Expose 'handle' as well as 'id' on LLProcess objects.Nat Goodspeed
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.
2012-01-21Convert LLProcess consumers from LLSD to LLProcess::Params block.Nat Goodspeed
Using a Params block gives compile-time checking against attribute typos. One might inadvertently set myLLSD["autofill"] = false and only discover it when things behave strangely at runtime; but trying to set myParams.autofill will produce a compile error. However, it's excellent that the same LLProcess::create() method can accept either LLProcess::Params or a properly-constructed LLSD block.
2012-01-20Per Richard, replace LLProcessLauncher with LLProcess.Nat Goodspeed
LLProcessLauncher had the somewhat fuzzy mandate of (1) accumulating parameters with which to launch a child process and (2) sometimes tracking the lifespan of the ensuing child process. But a valid LLProcessLauncher object might or might not have ever been associated with an actual child process. LLProcess specifically tracks a child process. In effect, it's a fairly thin wrapper around a process HANDLE (on Windows) or pid_t (elsewhere), with lifespan management thrown in. A static LLProcess::create() method launches a new child; create() accepts an LLSD bundle with child parameters. So building up a parameter bundle is deferred to LLSD rather than conflated with the process management object. Reconcile all known LLProcessLauncher consumers in the viewer code base, notably the class unit tests.
