We're bound by the maximum value of off_t when handling
input bodies (we need to buffer to disk). Also ensure
we stop bad clients that send us unparseable lengths.
|
|
This should be more robust, faster and easier to deal
with than the ugly proof-of-concept regexp-based ones.
|
|
|
|
Explicitly track if our request will need Content-Length
or chunked body decoding.
|
|
The macro version lets us painlessly compare Ruby strings
against constant C strings. It wraps a C version of the
function which is necessary to avoid double evaluation while
preventing the user from having to type sizeof or strlen.
|
|
We'll need to keep track of a few more things to account
for content/chunk length and the temporary file descriptor
we'll need to use.
|
|
It's easy enough to just check a single equality without having
extra functions obscuring what's actually going on.
|
|
We'll need to be defining g_http_transfer_encoding and
g_content_length in the near future.
|
|
Just extra noise we don't care about. This also allows us to
undef the DEF_GLOBAL macro to avoid polluting the main
namespace.
|
|
It's mostly uninteresting code.
|
|
Create a Ruby string object before jumping into the function
to reduce the number of parameters passed and to take advantage
of our STR_NEW macro to reduce noise.
|
|
|
|
It doesn't conflict with any any common variables, tokens or
documentation pieces in the code.
|
|
Eliminate unnecessary jumping around in the source code to find
actions that lead to other actions and making it harder to
notice side effects when dealing with data we're sharing anyways.
|
|
There's also no point in validating field hits if our field is a
common field; so only do the validation for field length if we
need to allocate memory for a new field.
|

The "_value" suffix was used to denote the return type, which is
redundandant as it is already known at compile time (being that
this is C and functions have explicit return types). Furthurmore,
the "_value" is confusing since we're actually returning a "key"
when "value" is used in the context of "key-value" pairs.
|
|
More tightly integrate the C/Ruby portions with C/Ragel to avoid
the confusing the flow. Split out some files into hopefully
logical areas so it's easier to focus on more
interesting/volatile code.
|
|
So that blame falls on Eric if stuff breaks.
|
|
typedefs can be misleading for aggregate types, a struct is a
struct.
|
|
Use Data_Make_Struct instead of Data_Wrap_Struct to avoid extra
steps/code in object allocation. The GC will also free()
implicitly if no free callback is passed to Data_Make_Struct,
and we don't need an extra method here...
Since we're more comfortable with object management nowadays,
just make the data_get() fail with an assertion failure if it
somehow (very unlikely) ends up getting a NULL parser object.
Unicorn itself has no way of recovering other than throwing
errors to clients anyways and we have bigger problems if there's
a GC bug causing this.
Then, finally, reduce the size of our http_parser struct even
more (we'll add an int back later) since we know it's safe to
do so...

We couldn't do proper namespacing for the C module so there was
a potential conflict with Init_http11() in Mongrel. This was
needed because Mongrel's HTTP parser could be used in some
applications and we may be unfortunate enough need to support
them.
