tests (#158756)
These no longer compile because the warning now defaults to an error
after #157364, so downgrade the error to a warning for now; I’m not
familiar enough with either LLDB or MacOS to fix these warnings properly
(assuming they’re unintended).

after PR 138209 stopped applying data formatters
for T** by default, and this test expects that to
work. We'll need to figure out if we want to drop
this test, or adapt NSError/other objc formatters to
descend an extra level or two of depth.

Change `lldbtest.expect` to require the regexes in `patterns` be found in order – when the
`ordered` parameter is true. This matches the behavior of `substrs`.
The `ordered` parameter is true by default, so this change also fixes tests by either
tweaking the patterns to work in order, or by setting `ordered=False`.
I have often wanted to test with `patterns` and also verify the order. This change
allows that.

The NSError summary provider was fetching and printing the `_code` field
as an unsigned integer, but it's defined to be an NSInteger, which is
signed.

This fix is based on a problem with cxx_compiler and cxx_linker macros
on Windows.
There was an issue with compiler detection in paths containing "icc". In
such case, Makefile.rules thought it was provided with icc compiler.
To solve that, utilities detection has been rewritten in Python.
The last element of compiler's path is separated, taking into account
the platform path delimiter, and compiler type is extracted, with regard
of possible cross-toolchain prefix.

Starting with macOS 14, the `NSTimeZone` and `CFTimeZone` types are backed by swift
implementations. These tests won't pass on mainline lldb, since it doesn't have Swift
support.
|
|
The underlying timezone classes are being reimplemented in Swift, and these
strings will be Swift strings, without the ObjC `@` prefix. Leaving off the `@`
makes these tests usable both before and after the reimplmentation of
Foundation in Swift.

This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Remove the test override of `target.prefer-dynamic-value`.
Previously, the lldb default was `no-dynamic-values`. In rG9aa7e8e9ffbe (in
2015), the default was changed to `no-run-target`, but at that time the tests
were changed to be run with `no-dynamic-value`. I don't know the reasons for
not changing the tests, perhaps to avoid determining which tests to change, and
what about them to change.
Because `no-run-target` is the lldb default, I think it makes sense to make it
the test default too. It puts the test config closer to what's used in
practice.
This change removes the `target.prefer-dynamic-value` override, and for those
tests that failed, they have been updated to explicitly use
`no-dynamic-values`. Future changes could update these tests to use dynamic
values too, or they can be left as is to exercise non-dynamic typing.

This reverts commit 602ab188a7e18b97d9af95e17271e8fbee129081.
The patch replicated an lldbassert for a certain type of NSNumber for tagged
pointers. This really shouldn't be an assert since we don't do anything wrong
with these numbers, we just don't print a summary. So this patch changed the
lldbassert to a log message in reverting the revert.

The ObjC runtime offers both signed & unsigned tagged pointer value
accessors to tagged pointer providers, but lldb's tagged pointer
code only implemented the unsigned one. This patch adds an
emulation of the signed one.
The motivation for doing this is that NSNumbers use the signed
accessor (they are always signed) and we need to follow that in our
summary provider or we will get incorrect values for negative
NSNumbers.
The data-formatter-objc test file had NSNumber examples (along with lots of other
goodies) but the NSNumber values weren't tested. So I also added
checks for those values to the test.
I also did a quick audit of the other types in that main.m file, and
it looks like pretty much all the other values are either intermediates
or are tested.

Add preconditions to `TestBase.expect()` that catch semantically invalid calls
that happen to succeed anyway. This also fixes the broken callsites caught by

2. `self.expect("lldb command", "assert message", "some substr")`

distantPast value
Summary:
Certain `NSDate` constructors return a special `NSConstantDate` class which
currently ends up being unformatted as it's not in the list of supported classes
for the NSDate formatter. This patch adds that class to the supported class list
so LLDB produces a summary for it.
One of these special constructors is `[NSDate distantPast]` which returns the
date for `0001-01-01 00:00:00 UTC`. LLDB has a special case for formatting this
date but for some reason we did hardcode the wrong summary string in that
special case. Maybe the summary string was correct back when the code was
written but it isn't correct anymore (`distantPast` isn't actually defined to be
a special date but just some 'a guaranteed temporal boundary.' so maybe someone
changed the value in the last 10 years).
If someone else is wondering why we even have this special case for
`distantPast` but not for the future. The reason seems to be that our date
formatting for really old dates is off by 24 hours. So for example, adding one
second to `distantPast` will cause LLDB to print `0000-12-30 00:00:01 UTC`
(which is 24 hours behind the expected result). So to make our code appear to be
correct it seems we just hardcoded the most common NSDate result from that time
span. I'll replace that logic with a generic solution in a probably more
invasive follow up patch.
I also took the freedom to replace the magic value `-63114076800` with some
constant + documentation. I heard there are some people that don't know from the
top of their head that there are 63114076800 seconds between 1. Jan 0001 and 1.
January 2001 in whatever calendar system NSDate is using.

Summary:
When printing an NSDate (for example with `NSLog` or `po`) the seconds value is
always rounded down. LLDB's own formatter however isn't following that behaviour
which leads to situations where the formatted result is sometimes one second
off. For example:
```
(lldb) p [NSDate dateWithTimeIntervalSince1970:0.1]
(__NSTaggedDate *) $1 = [...] 1970-01-01 00:00:01 UTC
(lldb) po [NSDate dateWithTimeIntervalSince1970:0.1]
1970-01-01 00:00:00 +0000
(lldb) p [NSDate dateWithTimeIntervalSince1970:0.6]
(__NSTaggedDate *) $4 =[...] 1970-01-01 00:00:01 UTC
(lldb) po [NSDate dateWithTimeIntervalSince1970:0.6]
1970-01-01 00:00:00 +0000
```
This patch just always rounds down the seconds value we get from the NSDate
object.

This patch improves data formatting for CFDictionaryRef and CFSetRef.
It uses the same data-formatter as NSCFDictionaries and NSCFSets introduced
previously but did require some adjustments in Core::ValueObject.
Since the "Ref" types are opaque pointers to the actual CF containers, if the
value object has a synthetic value, lldb will use the opaque pointer's pointee
type to create the new ValueObjectChild needed to dereference the ValueObject.
This allows the "Ref" types to behaves the same as CF containers when used with
the `frame variable` command, the SBAPI or in Xcode's variable inspector.
This patch also adds support for incomplete types in ValueObject.

This patch improves data formatting for CoreFoundation containers:
CFDictionary and CFSet.
These data formatters make the containers and their children appear in Xcode's
variables view (and on the command line) without having to expand the
data structure.
Previous implementation only supported showing the container's element count.
```
(lldb) frame var dict
(__NSCFDictionary *) dict = 0x00000001004062b0 2 key/value pairs
(lldb) frame var set
(__NSCFSet *) set = 0x0000000100406330 2 elements
```
Now the variable can be dereferenced to dispaly the container's children:
```
(lldb) frame var *dict
(__NSCFDictionary) *dict = {
[0] = {
key = 0x0000000100004050 @"123"
value = 0x0000000100004090 @"456"
}
[1] = {
key = 0x0000000100004030 @"abc"
value = 0x0000000100004070 @"def"
}
}
(lldb) frame var *set
(__NSCFSet) *set = {
[0] = 0x0000000100004050 @"123"
[1] = 0x0000000100004030 @"abc"
}

(This is D68010 but I also set the new parameter in LibStdcpp.cpp to fix
the Debian tests).
Summary:
Printing a summary for an empty NSPathStore2 string currently prints random bytes behind the empty string pointer from memory (rdar://55575888).
It seems the reason for this is that the SourceSize parameter in the `ReadStringAndDumpToStreamOptions` - which is supposed to contain the string
length - actually uses the length 0 as a magic value for saying "read as much as possible from the buffer" which is clearly wrong for empty strings.
This patch adds another flag that indicates if we have know the string length or not and makes this behaviour dependent on that (which seemingly
was the original purpose of this magic value).

Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:
lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
lldb-shell :: Reproducer/TestGDBRemoteRepro.test
