liquid-c's Introduction

Liquid::C

Partial native implementation of the liquid ruby gem in C.

Installation

Add these lines to your application's Gemfile:

gem 'liquid', github: 'Shopify/liquid', branch: 'main'
gem 'liquid-c', github: 'Shopify/liquid-c', branch: 'main'

And then execute:

$ bundle

Usage

require 'liquid/c'

then just use the documented API for the liquid Gem.

Restrictions

Input strings are assumed to be UTF-8 encoded strings
Tag#parse(tokens) is given a Liquid::Tokenizer object, instead of an array of strings, which only implements the shift method to get the next token.

Performance

To compare Liquid-C's performance with plain Liquid run

bundle exec rake compare:lax

The latest benchmark results are shown below:

$ bundle exec rake compare:lax

Compilation failing due to a warning

The liquid-c gem is bundled in Jekyll and when I updated my bundle earlier on it updated liquid-c from 0.0.2 to 0.0.3. It failed during the compilation. I tried again installing only the gem, it also failed with the following log:

$ gem install liquid-c -v '0.0.3'

I also tried to install v0.0.2 with no problems.

I don't know if it has anything to do with my setup but I managed to get past this by installing liquid-c by itself with the -w cflag in order to ignore warnings during compilation:

$ gem install liquid-c -v '0.0.3' -- --with-cflags=-w

It can probably be corrected with a modification to ext/liquid_c/extconf.rb

Encoding::CompatibilityError when using a binary encoded output

We were getting the error "incompatible character encodings: ASCII-8BIT and UTF-8 (Encoding::CompatibilityError)" after #58 was introduced when trying to render using a binary encoded output buffer.

This error can be demonstrated with the following code

output = String.new(capacity: 10) # defaults to encoding: Encoding::BINARY
template = Liquid::Template.parse("ü{{ unicode_char }}")
template.render!({ 'unicode_char' => 'ñ' }, output: output) # raises Encoding::CompatibilityError

This was happening because the OP_WRITE_RAW instruction was writing using rb_str_cat and a character pointer, which isn't encoding aware, so was writing the UTF-8 text to the binary string. After that, the output buffer is no longer ascii compatible or UTF-8 compatible, so will get a compatibility error when a unicode encoded string with non-ascii compatible characters is written to the output buffer, as happens when writing a string variable.

Using Liquid in C

Hi Liquid team,

Thank you for designing liquid, I love it.

It's possible to use "liquid" inside C? There is any example to use in pure C and not Ruby?

Thanks in advance.

Best,
M.

Doesn't support key-value arguments for filters without spaces

Vanilla liquid supports keyword arguments without spaces around the colons.

❯ b rails c
irb(main):001:0> Liquid::Template.parse("{{ 'home.welcome' | t: count: 1 }}").render
=> "translation missing: en.home.welcome"
irb(main):002:0> require 'liquid/c'
=> true
irb(main):003:0> Liquid::Template.parse("{{ 'home.welcome' | t: count: 1 }}").render
=> "Liquid error: wrong number of arguments (3 for 1..2)"
irb(main):004:0> Liquid::Template.parse("{{ 'home.welcome' | t : count : 1 }}").render
=> "translation missing: en.home.welcome"

Implement `if`/`unless` as an instruction

Introducing an OP_BRANCHUNLESS <offset> instruction (inspired by Ruby).

Pseudo bytecode:

<condition>         <= evaled condition is on stack
OP_BRANCHUNLESS  2  <= jump +2 bytes unless stack_pop
<2 bytes of body>
<end if>

To keep things simple at first, we could compile only the if/unless without any else branches.

This would be the first jump type instruction. if is the simplest one, so it's a good starting point. After this, porting for, case, and, or to instructions will be possible.

However, I think this is where the const_ptr pointer breaks. Any instruction using the const_ptr inside a loop/jump will cause it to be out of sync w/ ip. This should be fixed first.

TypeError: no _dump_data is defined for class Liquid::C::ResourceLimits

Hello there,

when I try to update to latest 4.1 i have this on my specs

     TypeError:
       no _dump_data is defined for class Liquid::C::ResourceLimits

error come from this :

Rails.cache.fetch("render_template/liquid_template/website/#{template_version}/#{name}".freeze, compress: true) do
      Liquid::Template.new.parse(body)
    end

my current version is 4.0. liquid 5.3, ruby 2.7.5, rails 5.2.7

Any idea ? Thanks !

Replace the moving constant pointer with a constant table

The moving constant pointer optimizes for lookup of unique constants, as is the case when delegating to ruby AST objects. However, these will become less common as we add VM compilation for more of the ruby AST nodes.

As mentioned in #83, the moving constant pointer would require the use of two offsets for both ip and const_ptr in order to handle jump instructions for control flow tags. Conditional branching will become a hot code path once we compile control flow tags to VM instructions, so we probably don't want the added overhead of managing the additional jump offset for the moving constant pointer.

We might want to start by using a struct for the instruction pointer pair (ip, const_ptr) to reduce the amount of code affected by switching away from the moving constant pointer.

We could then introduce a constant table which can be referenced by index from instructions. We could start by using this for instructions that are more likely to re-use the same constant (e.g. OP_FILTER, OP_LOOKUP_CONST_KEY, OP_FIND_STATIC_VAR).

Since we are using byte code instructions, we will have to handle multi-byte index references. If we want to handle 24-bit length source string (i.e. 16 MiB), then I think that means we need to either handle 24-bit indexes to be conservative (assuming it isn't possible to introduce more constants than byte of source code but is possible to introduce a unique constant per 256 bytes of source code). However, we could instrument the code to determine if a 24-bit index is actually necessary in practice, if we want to remove/avoid support for it. We should at least be able to treat a 24-bit index as a cold code path.

Reading a 16-bit index does seem like it could end up being a hot code path. For performance, we might want to design for a little-endian CPU that can efficiently read a 16-bit aligned integer (e.g. x86, AMD64). To achieve the alignment of a 16-bit integer when adding an instruction which would have it unaligned, we can have an unaligned version of the instruction which simply skips over a padding/alignment byte then falls through to the aligned version of the instruction in the VM switch statement. We could try this strategy first in a separate PR for the OP_PUSH_INT16.

potential read past end of buffer in `skip_white`

@TonyZou

I was doing a general code review, and I noticed that:

skip_white can return a pointer past the end of the input buffer
none of its callers check for this

Solution should be to add logic to skip_white to return NULL when the buffer ends (just like scan_past), and to wrap all calls to skip_white in the TRY_PARSE macro.

strict_filters no longer working

Hi,

I'm trying to update liquid-c in a project that I work on but I noticed that strict_filters is no longer working (perhaps since this commit).

I've created this gist reproducing the problem: https://gist.github.com/rafaelss/5ed21e59ad2cc5d82acf4b089b5697af

Running working.rb raises the exception correctly (fef8329 is the ref I'm currently using in the project), but running not_working.rb does not.

Is there anything I should change to make the most recent commits work correctly?

Segfault when exception renderer raises on non-internal errors in SFR

I don't think it's an urgent issue, because it only happens when an exception is raised from inside the exception renderer, and only the exception is raised from inside this else branch. Raising from anywhere else in the method does not cause a segfault.

So, as long as LiquidExceptionRenderer#track_liquid_unreported_exception does not raise, no segfault should happen.

The issue seems to be that ip is null. But why is it null, and only on that else branch? I don't know.

Install problem

I am using liquid-c in my jekyll based site and cant seem to get it to install on one workstation.

Ruby is installed with brew and the usual configurations are in place. I reinstalled Ruby and did a bunch of other trials, but always end up with this problem. The same site and setup works on other machines and on this machine with using jekyll-docker.

Any tip on what to look at?


Here is the error message I am getting:

Compile nested block bodies into their parent block body object

Currently, the library writes liquid VM code into separate growable buffers (in vm_assembler_t) for each Liquid::C::BlockBody object. However, for block body serialization and deserialization (#77) we will want to share an immutable memory allocation across block bodies, so block bodies will need offsets into that shared memory for execution.

Since block bodies will be connected in this way for execution, we may also want to make parsing more efficient by re-using a vm_assembler_t for a block body once that block body has finished being compiled (e.g. when its parent block tag is finished compiling), by not embedding it in the block_body_t struct. That way we could save on the number of memory allocations for these vm_assembler_t buffers and will have less vm_assembler_t buffers to combine at the end of parsing / compilation. For instance, we could have one vm_assembler_t per-level of nesting in the template.

Support for ruby 2.7.4p191 [x86_64-darwin21]

I'm having trouble installing liquid-c on Ruby 2.7.4 on macOS Monterey.

It installs correctly on Ruby 3.0.2 on the same machine.

I've tried switching to using the main branch on github as a source in bundler and that works too.

I have completely reinstalled xcode, homebrew and ruby (via asdf), hoping that would help, but to no avail.

Some output from gem env:

Homepage & source code URLs missing in RubyGems listing

Please update the RubyGems metadata to include either the homepage or source code repo (or both). They're currently missing from https://rubygems.org/gems/liquid-c, making it hard to find the source code.

Add support for serializing liquid templates along with their VM code

Once #59 and #60 are merged, the liquid benchmarks show that 60% of the time to parse and render a template happens during parsing. We could save a lot of that time by persisting (e.g. to a cache initially) the parsed template so that it can be re-used for further renders.

I think we should have the persisted format be fairly stable, such that it can be used across deploys of the application. As such, I don't think we should just use Marshal on the liquid gem's parse tree, since that can easily lead to breaking changes from code written without awareness of liquid-c. Instead, we should re-parse tag nodes on deserialization if that don't support liquid VM compilation. For code that is compiled into liquid VM code, we should include two versions in the serialized VM code, one for the liquid-c and one for the application, so either can bump these versions to avoid rendering incompatible VM code.

So the serialized block bodies will consist of the following sections:

liquid VM instructions that don't require deserialization for execution
An array of marshal dumped ruby constants and will require marshal loading on deserialization
Uncompiled tags to parse on deserialization, including the type of tag (e.g. regular, block or raw) and references to any block bodies and "unknown tags" (i.e. handled from Liquid::Block#unknown_tag, such as elsif for Liquid::If)

This will require combining the VM assembler buffers for these block bodies together and removing the assumption that each block body will own its own assembler buffers. Instead, the block bodies should instead reference offsets into the shared buffer for execution. This could be done before adding serialization support (#78).

To keep the ruby constant array simple, we will want to compile the non-ruby constant arguments into the VM instructions as immediate arguments. Currently this isn't the case for OP_RENDER_VARIABLE_RESCUE and OP_WRITE_RAW. Note that doing this for OP_WRITE_RAW will add copying overhead that won't be beneficial without using it for serialization.

Another possible application version compatibility concern is the Liquid::ParseContext, which is an argument for parsing, which can end up being saved and used for rendering (e.g. for parsing included templates). To check for compatibility, we may want to require the application to pass in the same parse options for both parsing and deserializing to consider the serialized template to be compatible with the current application version. We may also want to check the parse context after parsing to make sure the application doesn't depend on mutations of the parse context.

Ruby 3.1

Hello, when i'm trying to use ruby 3.1 i get this error ... Any idea ? Using Liquid 5.3, latest liquid-c, thanks a lot !

Add profiling support

Right now, only Ruby Liquid has profiling. Profiling Liquid templates in production triggers Ruby Liquid to render the template, not Liquid::C. This is leading us on the wrong paths RE what to optimize.

I need to look at how other VMs are doing profiling with low overhead.

Stable?

The version on Rubygems.org is v0.0.2. This tells me, as a subscriber of SemVer, that it's not stable – that it should not be used in production environments.

Is this assumption true? The README does not discuss versioning practices. What do you think about versioning it (at least at the MAJOR level) alongside Liquid-ruby?

What's the rational behind joining array elements on display?

https://github.com/Shopify/liquid-c/blob/master/ext/liquid_c/vm.c#L117-L130 seems to be responsible for making the test

The current test (https://github.com/Shopify/liquid-c/blob/master/test/unit/variable_test.rb#L124-L126) is implemented as follows:

 def test_write_array
    output = Liquid::Template.parse("{{ ary }}").render({ "ary" => ["foo", 123, ["nested", "ary"], nil, 0.5] })
    assert_equal("foo123nestedary0.5", output)
  end

However, I can hardly find any reason for such behavior. Instead, I would expect the following assertion to pass:

output = Liquid::Template.parse("{{ ary }}").render({ "ary" => ["foo", 123, ["nested", "ary"], nil, 0.5] })
assert_equal('["foo", 123, ["nested", "ary"], nil, 0.5]', output)

Would you consider changing this behavior, which I believe would be equivalent to just removing a couple of lines of code without having to add any new ones https://github.com/Shopify/liquid-c/blob/master/ext/liquid_c/vm.c#L117-L130 ?
