There are a few FIXMEs that will need to be addressed, but this
implements most of the prototype method. The FIXMEs are mostly related
to range formatting, which has been entirely ignored so far. But other
than that, the following will need to be addressed:
* Determining flexible day periods must be made locale-aware.
* DST will need to be determined and acted upon.
* Time zones other than UTC and calendars other than Gregorian are
ignored.
* Some of our results differ from other engines as they have some
format patterns we do not. For example, they seem to have a lonely
{dayPeriod} pattern, whereas our closest pattern is
"{hour} {dayPeriod}".
Unlike the locale, the data locale has Unicode locale extensions removed
(e.g. the data locale for "en-US-u-ca-gregory" is just "en-US"). Cache
the data locale for LibUnicode lookups during formatting.
The parsing in parse_calendar_symbols() might be a bit more verbose than
it really needs to be, but it is to ensure the symbols are generated in
a known order that we can control with enumerations.
This was an oversight in e42d954743.
These fields should always follow the locale preference in the CLDR.
Overriding these fields would permit formats like "h:mm:ss" to result in
strings like "1:2:3" instead of "1:02:03".
TR-35's Matching Skeleton algorithm dictates how user requests including
fractional second digits should be handled when the CLDR format pattern
does not include that field. When the format pattern contains {second},
but does not contain {fractionalSecondDigits}, generate a second pattern
which appends "{decimal}{fractionalSecondDigits}" to the {second} field.
TR-35 does define lengths for {ampm}, but they are unused by ECMA-402.
To the contrary, defining the day_period length for this segment will
prevent BasicFormatMatcher from ever selecting a pattern that contains
this segment. Instead, ECMA-402 will only use the short length for
{ampm} segments.
Port the ubiquitous dos2unix tool to Serenity. Dos2Unix is a suite of
tools for converting file line endings, from dos/mac to unix and unix
to dos/mac.
If we're sending an urgent signal (i.e. due to unexpected conditions)
and the Process did not setup any signal handler, we should immediately
terminate the Thread, to ensure the current trap frame is preserved for
the impending core dump.
This is an encapsulation of the common work done by all of our
single-client IPC servers on startup:
1. Create a Core::LocalSocket, taking over an accepted fd.
2. Create an application-specific ClientConnection object,
wrapping the socket.
It's not a huge change in terms of lines saved, but I do feel that it
improves expressiveness. :^)
This encapsulates what our multi-client IPC servers typically do on
startup:
1. Create a Core::LocalServer
2. Take over a listening socket file descriptor from SystemServer
3. Set up an accept handler for incoming connections
IPC::MultiServer does all this for you! All you have to do is provide
the relevant client connection type as a template argument.
