-> by default settings will be loaded from the settings.xml file in the current skin folder
-> settings are applied *after* the session specific options
The logic in llcommandlineparser.cpp's setControlValueCB() callback function
for converting command-line switch argument values from string to the actual
type of the map-to settings variable had a couple special cases for boolean
and LLSD array. But for S32, U32 and F32, it simply used default LLSD
string-to-numeric conversion. LLSD's string-to-numeric conversion is a bit
lame: for non-numeric strings, it shrugs and returns 0.
Introduce onevalue() and badvalue() helper functions that, like certain errors
during command-line parsing, throw LLCLPError. Use them to streamline certain
redundancies in setControlValueCB(). Introduce convertTo<T>() helper function
that uses boost::lexical_cast() for slightly more stringent conversions. Add
cases for U32, S32 and F32 targets.
setControlValueCB() is actually called only by LLControlGroupCLP::notify(),
not during actual command-line parsing.
Make LLControlGroupCLP::notify() return bool. Make it catch LLCLPError, set
the error for getErrorMessage() and return false on that exception.
Package LLAppViewer::initConfiguration()'s response to initParseCommandLine()
returning false as a new handleCommandLineError() function; invoke it both
there and when LLControlGroupCLP::notify() returns false.
Previous CHOP-959 logic set a flag to remember that settings variable
RenderQualityPerformance was set (by --graphicslevel), so it could be applied
once LLViewerWindow is constructed. But on first viewer run, LLViewerWindow
constructor calls LLFeatureManager::applyRecommendedSettings(), which resets
that settings variable! So don't just set a flag, actually capture the
requested RenderQualityPerformance value for later.
Route --url and --slurl command-line switches through a common settings
variable. Treat them uniformly now. (Previously, passing --url would notice a
grid-specific SLURL and preselect that grid; --slurl wouldn't. Now both do.)
The cmd_line.xml entries:
analyzeperformance
crashonstartup
debugsession
disablecrashlogger
logmetrics
logperformance
noquicktime
replaysession
all specify map-to settings.xml variables -- none of which existed! Introduce
such variables. Instead of detecting the presence of a particular switch in
the command-line parser, use the value of its corresponding settings variable.
Use map-to in cmd_line.xml to inform the command-line processor that the
target variable for --graphicslevel is RenderQualityPerformance.
That lets us eliminate clunky llappviewer.cpp switch from '0' to 0, etc.
Moreover, previous switch statement only accepted 0 - 3, whereas
LLFeatureManager::setGraphicsLevel() actually accepts 0 - 6. Introduce
LLFeatureManager::isValidGraphicsLevel() and use that to validate.
Replace switch statement in setGraphicsLevel() mapping int constants to string
literals with static vector of level names, using same data for mapping as for
validating level numbers.
Introduce LLCoros::setStackSize(), with a compile-time default value we hope
we never have to use. Make LLAppViewer call it with the value of the new
settings variable CoroutineStackSize as soon as we've read settings files.
(While we're at it, notify interested parties that we've read settings files.)
Give CoroutineStackSize a default value four times the previous default stack
size. Make LLCoros::launch() pass the saved stack size to each new coroutine
instance.
Re-enable lleventcoro integration test. Use LLSDMap() construct rather than
LLSD::insert(), which used to return the modified object but is now void.
