Updates charset-normalizer from 3.3.2 to 3.4.0



Release notes

Sourced from charset-normalizer's releases.




Version 3.4.0


🚀 charset-normalizer is raising awareness around HTTP/2, and HTTP/3!


Did you know that Internet Explorer 11 shipped with an optional HTTP/2 support back in 2013? also libcurl did ship it in 2014[...]
All of this while our community is still struggling to make a firm advancement in HTTP clients. Now, many of you use Requests
as the defacto http client, now, and for many years now, Requests has been frozen. Being left in a vegetative state and not evolving,
this blocked millions of developers from using more advanced features.


We promptly invite Python developers to look at the drop-in replacement for Requests, namely Niquests.
It leverage charset-normalizer in a better way! Check it out, you will be positively surprised! Don't wait another decade.


We are thankful to @​microsoft and involved parties for funding our work through the Microsoft FOSS Fund program.


3.4.0 (2024-10-08)


Added


    

  • Argument --no-preemptive in the CLI to prevent the detector to search for hints.
    • 

  • Support for Python 3.13 (#512)
    • 



Fixed


    

  • Relax the TypeError exception thrown when trying to compare a CharsetMatch with anything else than a CharsetMatch.
    • 

  • Improved the general reliability of the detector based on user feedbacks. (#520) (#509) (#498) (#407) (#537)
    • 

  • Declared charset in content (preemptive detection) not changed when converting to utf-8 bytes. (#381)

Release notes

Sourced from jinja2's releases.




3.1.4

PyPI: https://pypi.org/project/Jinja2/3.1.4/
Changes: https://jinja.palletsprojects.com/en/3.1.x/changes/#version-3-1-4


    

  • The xmlattr filter does not allow keys with / solidus, > greater-than sign, or = equals sign, in addition to disallowing spaces. Regardless of any validation done by Jinja, user input should never be used as keys to this filter, or must be separately validated first. GHSA-h75v-3vvj-5mfj
    • 



3.1.3


This is a fix release for the 3.1.x feature branch.








Changelog

Updates markdown from 3.5.1 to 3.7



Release notes

Sourced from markdown's releases.




Release 3.7


Changed


Refactor abbr Extension


A new AbbrTreeprocessor has been introduced, which replaces the now deprecated
AbbrInlineProcessor. Abbreviation processing now happens after Attribute Lists,
avoiding a conflict between the two extensions (#1460).


The AbbrPreprocessor class has been renamed to AbbrBlockprocessor, which

A call to Markdown.reset() now clears all previously defined abbreviations.


Abbreviations are now sorted by length before executing AbbrTreeprocessor

Abbreviations without a definition are now ignored. This avoids applying
abbr tags to text without a title value.


Added an optional glossary configuration option to the abbreviations extension.

[3.7] -- 2024-08-16


Changed


Refactor abbr Extension


A new AbbrTreeprocessor has been introduced, which replaces the now deprecated
AbbrInlineProcessor. Abbreviation processing now happens after Attribute Lists,
avoiding a conflict between the two extensions (#1460).


The AbbrPreprocessor class has been renamed to AbbrBlockprocessor, which
better reflects what it is. AbbrPreprocessor has been deprecated.

Updates markupsafe from 2.1.3 to 3.0.2



Release notes

Sourced from markupsafe's releases.




3.0.2


This is the MarkupSafe 3.0.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes.


PyPI: https://pypi.org/project/MarkupSafe/3.0.2/
Changes: https://markupsafe.palletsprojects.com/en/stable/changes/#version-3-0-2
Milestone: https://github.com./pallets/markupsafe/milestone/14?closed=1


    

  • Fix compatibility when __str__ returns a str subclass. #472
    • 

  • Build requires setuptools >= 70.1. #475
    • 



3.0.1


This is the MarkupSafe 3.0.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes.


PyPI: https://pypi.org/project/MarkupSafe/3.0.1/
Changes: https://markupsafe.palletsprojects.com/en/stable/changes/#version-3-0-1
Milestone: https://github.com./pallets/markupsafe/milestone/13?closed=1


    

  • Address compiler warnings that became errors in GCC 14. #466
    • 

  • Fix compatibility with proxy objects. #467
    • 



3.0.0


This is the MarkupSafe 3.0.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecations, or introduce potentially breaking changes. The 3.0.x branch is now the supported fix branch, the 2.1.x branch will become a tag marking the end of support for that branch. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. Test with warnings treated as errors to be able to adapt to deprecation warnings early.


PyPI: https://pypi.org/project/MarkupSafe/3.0.0/
Changes: https://markupsafe.palletsprojects.com/en/stable/changes/#version-3-0-0
Milestone: https://github.com./pallets/markupsafe/milestone/10?closed=1


    

  • Support Python 3.13 and its experimental free-threaded build. #461
    • 

  • Drop support for Python 3.7 and 3.8.
    • 

  • Use modern packaging metadata with pyproject.toml instead of setup.cfg. #348
    • 

  • Change distutils imports to setuptools. #399
    • 

  • Use deferred evaluation of annotations. #400
    • 

  • Update signatures for Markup methods to match str signatures. Use positional-only arguments. #400
    • 

  • Some str methods on Markup no longer escape their argument: strip, lstrip, rstrip, removeprefix, removesuffix, partition, and rpartition; replace only escapes its new argument. These methods are conceptually linked to search methods such as in, find, and index, which already do not escape their argument. #401
    • 

  • The __version__ attribute is deprecated. Use feature detection, or importlib.metadata.version("markupsafe"), instead. #402
    • 

  • Speed up escaping plain strings by 40%. #434
    • 

  • Simplify speedups implementation. #437
    • 



2.1.5


This is a fix release for the 2.1.x feature release branch. It fixes bugs but does not otherwise change behavior and should not result in breaking changes.


Fixes a regression in striptags behavior from 2.14. Spaces are now collapsed correctly.



2.1.4


This is a fix release for the 2.1.x feature release branch. It fixes bugs but does not otherwise change behavior and should not result in breaking changes.

[sanitizer_common] Fix UnwindFast on SPARC (#101634)
69555e0 
```
  UBSan-Standalone-sparc :: TestCases/Misc/Linux/diag-stacktrace.cpp
```
`FAIL`s on 32 and 64-bit Linux/sparc64 (and on Solaris/sparcv9, too: the
test isn't Linux-specific at all). With
`UBSAN_OPTIONS=fast_unwind_on_fatal=1`, the stack trace shows a
duplicate innermost frame:
```
compiler-rt/test/ubsan/TestCases/Misc/Linux/diag-stacktrace.cpp:14:31: runtime error: execution reached the end of a value-returning function without returning a value
    #0 0x7003a708 in f() compiler-rt/test/ubsan/TestCases/Misc/Linux/diag-stacktrace.cpp:14:35
    #1 0x7003a708 in f() compiler-rt/test/ubsan/TestCases/Misc/Linux/diag-stacktrace.cpp:14:35
    #2 0x7003a714 in g() compiler-rt/test/ubsan/TestCases/Misc/Linux/diag-stacktrace.cpp:17:38
```
which isn't seen with `fast_unwind_on_fatal=0`.

This turns out to be another fallout from fixing
`__builtin_return_address`/`__builtin_extract_return_addr` on SPARC. In
`sanitizer_stacktrace_sparc.cpp` (`BufferedStackTrace::UnwindFast`) the
`pc` arg is the return address, while `pc1` from the stack frame
(`fr_savpc`) is the address of the `call` insn, leading to a double
entry for the innermost frame in `trace_buffer[]`.

This patch fixes this by moving the adjustment before all uses.

Tested on `sparc64-unknown-linux-gnu` and `sparcv9-sun-solaris2.11`
(with the `ubsan/TestCases/Misc/Linux` tests enabled).

(cherry picked from commit 3368a32)

[lldb][LoongArch] Fix the incorrect floating-point register dwarf number
eb1b9fc 
According to the documentation described at
https://github.com./loongson/la-abi-specs/blob/release/ladwarf.adoc, the
dwarf numbers for floating-point registers range from 32 to 63.

An incorrect dwarf number will prevent the register values from being
properly restored during unwinding.

This test reflects this problem:

```
loongson@linux:~$ cat test.c

void foo() {
  asm volatile ("movgr2fr.d $fs2, $ra":::"$fs2");
}
int main() {
  asm volatile ("movgr2fr.d $fs2, $sp":::"$fs2");
  foo();
  return 0;
}

loongson@linux:~$ clang -g test.c  -o test

```

[lldb][Linux] Add Control Protection Fault signal (#122917)
5658bc4 
This will be sent by Arm's Guarded Control Stack extension when an
invalid return is executed.

The signal does have an address we could show, but it's the PC at which
the fault occured. The debugger has plenty of ways to show you that
already, so I've left it out.

```
(lldb) c
Process 460 resuming
Process 460 stopped
* thread #1, name = 'test', stop reason = signal SIGSEGV: control protection fault
    frame #0: 0x0000000000400784 test`main at main.c:57:1
   54  	  afunc();
   55  	  printf("return from main\n");
   56  	  return 0;
-> 57  	}
(lldb) dis
<...>
->  0x400784 <+100>: ret
```

The new test case generates the signal by corrupting the link register
then attempting to return. This will work whether we manually enable GCS
or the C library does it for us.

(in the former case you could just return from main and it would fault)

[AArch64][SME] Spill p-regs as z-regs when streaming hazards are poss…
82c6b8f 
…ible (#123752)

This patch adds a new option `-aarch64-enable-zpr-predicate-spills`
(which is disabled by default), this option replaces predicate spills
with vector spills in streaming[-compatible] functions.

For example:

```
str	p8, [sp, #7, mul vl]            // 2-byte Folded Spill
// ...
ldr	p8, [sp, #7, mul vl]            // 2-byte Folded Reload
```

Becomes:

```
mov	z0.b, p8/z, #1
str	z0, [sp]                        // 16-byte Folded Spill
// ...
ldr	z0, [sp]                        // 16-byte Folded Reload
ptrue	p4.b
cmpne	p8.b, p4/z, z0.b, #0
```

This is done to avoid streaming memory hazards between FPR/vector and
predicate spills, which currently occupy the same stack area even when
the `-aarch64-stack-hazard-size` flag is set.

This is implemented with two new pseudos SPILL_PPR_TO_ZPR_SLOT_PSEUDO
and FILL_PPR_FROM_ZPR_SLOT_PSEUDO. The expansion of these pseudos
handles scavenging the required registers (z0 in the above example) and,
in the worst case spilling a register to an emergency stack slot in the
expansion. The condition flags are also preserved around the `cmpne` in
case they are live at the expansion point.

[lldb][TypeSystemClang] Initialize ClassTemplateSpecializationDecl's …
c269182 
…StrictPackMatch field (#126215)

This addresses the MSAN failure reported
in
llvm/llvm-project#125791 (comment):
```
==5633==WARNING: MemorySanitizer: use-of-uninitialized-value
    #0 in clang::ASTNodeImporter::CallOverloadedCreateFun<clang::ClassTemplateSpecializationDecl>::operator()
    #1 in bool clang::ASTNodeImporter::GetImportedOrCreateSpecialDecl<...>
...
```

The ASTImporter reads `D->hasStrictPackMatch()` and forwards it to the
constructor of the destination `ClassTemplateSpecializationDecl`. But if
`D` is a decl that LLDB created from debug-info, it would've been
created using `ClassTemplateSpecializationDecl::CreateDeserialized`,
which doesn't initialize the `StrictPackMatch` field.

This patch just initializes the field to a fixed value of `false`, to
preserve previous behaviour and avoid the use-of-uninitialized-value.

An alternative would be to always initialize it in the
`ClassTemplateSpecializationDecl` constructor, but there were
reservations about providing a default value for it because it might
lead to hard-to-diagnose problems down the line.

[mlir] Fix FunctionOpInterface impl for external func (#124693)
8b284dc 
For function declarations (i.e. func op has no entry block), the
FunctionOpInterface method `insertArgument` and `eraseArgument` will
cause segfault. This PR guards against manipulation of empty entry block
by checking whether func op is external.

An example can be seen in google/heir#1324

The segfault trace

cause segfault. This PR guards against manipulation of empty entry block
by checking whether func op is external.

An example can be seen in google/heir#1324

[AArch64][SVE] Improve fixed-length addressing modes. (#129732)
f01e760 
When compiling VLS SVE, the compiler often replaces VL-based offsets
with immediate-based ones. This leads to a mismatch in the allowed
addressing modes due to SVE loads/stores generally expecting immediate
offsets relative to VL. For example, given:
```c

svfloat64_t foo(const double *x) {
  svbool_t pg = svptrue_b64();
  return svld1_f64(pg, x+svcntd());
}
```

When compiled with `-msve-vector-bits=128`, we currently generate:
```gas
foo:
        ptrue   p0.d
        mov     x8, #2
        ld1d    { z0.d }, p0/z, [x0, x8, lsl #3]
        ret
```

Instead, we could be generating:
```gas
foo:
        ldr     z0, [x0, #1, mul vl]
        ret
```

Likewise for other types, stores, and other VLS lengths.

This patch achieves the above by extending `SelectAddrModeIndexedSVE`
to let constants through when `vscale` is known.

[lldb][test] Skip libsanitizers tests for now (#130305)
6cc8b0b 
These are macOS tests only and are currently failing on the x86_64 CI
and on arm64 on recent versions of macOS/Xcode.

The tests are failing because we're stopping in:
```
Process 17458 stopped
* thread #1: tid = 0xbda69a, 0x00000002735bd000
  libsystem_malloc.dylib`purgeable_print_self.cold.1, stop reason = EXC_BREAKPOINT (code=1, subcode=0x2735bd000)
```
instead of the libsanitizers library. This seems to be related to
`-fsanitize-trivial-abi` support

Skip these for now until we figure out the root cause.

[flang][NFC] use hlfir.declare first result when both results are raw…
44261da 
… pointers (#132261)

Currently, the helpers to get fir::ExtendedValue out of hlfir::Entity
use hlfir.declare second result (`#1`) in most cases. This is because
this result is the same as the input and matches what FIR was getting
before lowering to HLFIR.

But this creates odd situations when both hlfir.declare are raw pointers
and either result ends-up being used in the IR depending on whether the
code was generated by a helper using fir::ExtendedValue, or via "pure
HLFIR" helpers using the first result.

This will typically prevent simple CSE and easy identification that two
operation (e.g load/store) are touching the exact same memory location
without using alias analysis or "manual detection" (looking for common
hlfir.declare defining op).

Hence, when hlfir.declare results are both raw pointers, use `#0` when
producing `fir::ExtendedValue`.
When `#0` is a fir.box, keep using `#1` because these are not the same. 
The only code change is in HLFIRTools.cpp and is pretty small, but there
is a big test fallout of `#1` to `#0`.

[AArch64][SVE] Use FeatureUseFixedOverScalableIfEqualCost for A510 an…
d2bcc11 
…d A520 (#132246)

Inefficient SVE codegen occurs on at least two in-order cores,
those being Cortex-A510 and Cortex-A520. For example a simple vector
add

```
void foo(float a, float b, float dst, unsigned n) {
    for (unsigned i = 0; i < n; ++i)
        dst[i] = a[i] + b[i];
}
```

Vectorizes the inner loop into the following interleaved sequence
of instructions.

```
        add     x12, x1, x10
        ld1b    { z0.b }, p0/z, [x1, x10]
        add     x13, x2, x10
        ld1b    { z1.b }, p0/z, [x2, x10]
        ldr     z2, [x12, #1, mul vl]
        ldr     z3, [x13, #1, mul vl]
        dech    x11
        add     x12, x0, x10
        fadd    z0.s, z1.s, z0.s
        fadd    z1.s, z3.s, z2.s
        st1b    { z0.b }, p0, [x0, x10]
        addvl   x10, x10, #2
        str     z1, [x12, #1, mul vl]
```

By adjusting the target features to prefer fixed over scalable if the
cost is equal we get the following vectorized loop.

```
         ldp q0, q3, [x11, #-16]
         subs    x13, x13, #8
         ldp q1, q2, [x10, #-16]
         add x10, x10, #32
         add x11, x11, #32
         fadd    v0.4s, v1.4s, v0.4s
         fadd    v1.4s, v2.4s, v3.4s
         stp q0, q1, [x12, #-16]
         add x12, x12, #32
```

Which is more efficient.

those being Cortex-A510 and Cortex-A520. For example a simple vector
add

```
void foo(float a, float b, float dst, unsigned n) {
    for (unsigned i = 0; i < n; ++i)
        dst[i] = a[i] + b[i];
}
```

Vectorizes the inner loop into the following interleaved sequence
of instructions.

```
        add     x12, x1, x10
        ld1b    { z0.b }, p0/z, [x1, x10]
        add     x13, x2, x10
        ld1b    { z1.b }, p0/z, [x2, x10]
        ldr     z2, [x12, #1, mul vl]
        ldr     z3, [x13, #1, mul vl]
        dech    x11
        add     x12, x0, x10
        fadd    z0.s, z1.s, z0.s
        fadd    z1.s, z3.s, z2.s
        st1b    { z0.b }, p0, [x0, x10]
        addvl   x10, x10, #2
        str     z1, [x12, #1, mul vl]
```

By adjusting the target features to prefer fixed over scalable if the
cost is equal we get the following vectorized loop.

```
         ldp q0, q3, [x11, #-16]
         subs    x13, x13, #8
         ldp q1, q2, [x10, #-16]
         add x10, x10, #32
         add x11, x11, #32
         fadd    v0.4s, v1.4s, v0.4s
         fadd    v1.4s, v2.4s, v3.4s
         stp q0, q1, [x12, #-16]
         add x12, x12, #32
```

Which is more efficient.

[AArch64][SVE] Pair SVE fill/spill into LDP/STP with -msve-vector-bit…
c80080f 
…s=128. (#134068)

When compiling with -msve-vector-bits=128 or vscale_range(1, 1) and when
the offsets allow it, we can pair SVE LDR/STR instructions into Neon
LDP/STP.

For example, given:
```cpp
#include <arm_sve.h>

void foo(double const *ldp, double *stp) {
  svbool_t pg = svptrue_b64();
  svfloat64_t ld1 = svld1_f64(pg, ldp);
  svfloat64_t ld2 = svld1_f64(pg, ldp+svcntd());
  svst1_f64(pg, stp, ld1);
  svst1_f64(pg, stp+svcntd(), ld2);
}
```

When compiled with `-msve-vector-bits=128`, we currently generate:
```gas
foo:
        ldr     z0, [x0]
        ldr     z1, [x0, #1, mul vl]
        str     z0, [x1]
        str     z1, [x1, #1, mul vl]
        ret
```

With this patch, we instead generate:
```gas
foo:
        ldp     q0, q1, [x0]
        stp     q0, q1, [x1]
        ret
```

This is an alternative, more targetted approach to #127500.

[lldb][Format] Display only the inlined frame name in backtraces if a…
1e153b7 
…vailable (#135343)

When a frame is inlined, LLDB will display its name in backtraces as
follows:
```
* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.3
  * frame #0: 0x0000000100000398 a.out`func() [inlined] baz(x=10) at inline.cpp:1:42
    frame #1: 0x0000000100000398 a.out`func() [inlined] bar() at inline.cpp:2:37
    frame #2: 0x0000000100000398 a.out`func() at inline.cpp:4:15
    frame #3: 0x00000001000003c0 a.out`main at inline.cpp:7:5
    frame #4: 0x000000026eb29ab8 dyld`start + 6812
```
The longer the names get the more confusing this gets because the first
function name that appears is the parent frame. My assumption (which may
need some more surveying) is that for the majority of cases we only care
about the actual frame name (not the parent). So this patch removes all
the special logic that prints the parent frame.

Another quirk of the current format is that the inlined frame name does
not abide by the `${function.name-XXX}` format variables. We always just
print the raw demangled name. With this patch, we would format the
inlined frame name according to the `frame-format` setting (see the
test-cases).

If we really want to have the `parentFrame [inlined] inlinedFrame`
format, we could expose it through a new `frame-format` variable (e..g.,
`${function.inlined-at-name}` and let the user decide where to place
things.

[AArch64][SVE] Fold ADD+CNTB to INCB/DECB (#118280)
34f9ddf 
Currently, given:
```cpp
uint64_t incb(uint64_t x) {
  return x+svcntb();
}
```
LLVM generates:
```gas
incb:
        addvl   x0, x0, #1
        ret
```
Which is equivalent to:
```gas
incb:
        incb    x0
        ret
```

However, on microarchitectures like the Neoverse V2 and Neoverse V3,
the second form (with INCB) can have significantly better latency and
throughput (according to their SWOG). On the Neoverse V2, for example,
ADDVL has a latency and throughput of 2, whereas some forms of INCB
have a latency of 1 and a throughput of 4. The same applies to DECB.
This patch adds patterns to prefer the cheaper INCB/DECB forms over
ADDVL where applicable.

[lldb] Remerge #136236 (Avoid force loading symbols in statistics col…
967434a 
…lection (#136795)

Fix a [test
failure](llvm/llvm-project#136236 (comment))
in #136236, apply a minor renaming of statistics, and remerge. See
details below.

# Changes in #136236

Currently, `DebuggerStats::ReportStatistics()` calls
`Module::GetSymtab(/*can_create=*/false)`, but then the latter calls
`SymbolFile::GetSymtab()`. This will load symbols if haven't yet. See
stacktrace below.

The problem is that `DebuggerStats::ReportStatistics` should be
read-only. This is especially important because it reports stats for
symtab parsing/indexing time, which could be affected by the reporting
itself if it's not read-only.

This patch fixes this problem by adding an optional parameter
`SymbolFile::GetSymtab(bool can_create = true)` and receiving the
`false` value passed down from `Module::GetSymtab(/*can_create=*/false)`
when the call is initiated from `DebuggerStats::ReportStatistics()`.

---

Notes about the following stacktrace:
1. This can be reproduced. Create a helloworld program on **macOS** with
dSYM, add `settings set target.preload-symbols false` to `~/.lldbinit`,
do `lldb a.out`, then `statistics dump`.
2. `ObjectFile::GetSymtab` has `llvm::call_once`. So the fact that it
called into `ObjectFileMachO::ParseSymtab` means that the symbol table
is actually being parsed.

# Changes in this PR top of the above

Fix a [test
failure](llvm/llvm-project#136236 (comment))
in `TestStats.py`. The original version of the added test checks that
all modules have symbol count zero when `target.preload-symbols ==
false`. The test failed on macOS. Due to various reasons, on macOS,
symbols can be loaded for dylibs even with that setting, but not for the
main module. For now, the fix of the test is to limit the assertion to
only the main module. The test now passes on macOS. In the future, when
we have a way to control a specific list of plug-ins to be loaded, there
may be a configuration that this test can use to assert that all modules
have symbol count zero.

Apply a minor renaming of statistics, per the
[suggestion](llvm/llvm-project#136226 (comment))
in #136226 after merge.

The underlying issue was that the `DeviceCompilerInstance` (used for
device-side CUDA compilation) was never initialized with a `Sema`, which
is required before constructing the `IncrementalCUDADeviceParser`.


https://github.com./llvm/llvm-project/blob/89687e6f383b742a3c6542dc673a84d9f82d02de/clang/lib/Interpreter/DeviceOffload.cpp#L32


https://github.com./llvm/llvm-project/blob/89687e6f383b742a3c6542dc673a84d9f82d02de/clang/lib/Interpreter/IncrementalParser.cpp#L31

Unlike the host-side `CompilerInstance` which runs `ExecuteAction`
inside the Interpreter constructor (thereby setting up Sema), the
device-side CI was passed into the parser uninitialized, leading to an
assertion or crash when accessing its internals.

To fix this, I refactored the `Interpreter::create` method to include an
optional `DeviceCI` parameter. If provided, we know we need to take care
of this instance too. Only then do we construct the
`IncrementalCUDADeviceParser`.
