* module/web/client.scm (ensure-uri): New helper.
(open-socket-for-uri): Accept a URI as a string or as a URI object.
(extend-request, sanitize-request): New helpers, like the
corresponding functions in (web server).
(decode-response-body): Add a reference to the HTTP/1.1 spec, and
use (ice-9 iconv).
(request): New helper, factoring all aspects of sending an HTTP
request and getting a response.
(http-get): Redefine in terms of http-get. Deprecate the
#:extra-headers argument in favor of #:headers. Allow a body. Add a
#:streaming? argument, subsuming the functionality of http-get*.
(http-get*): Deprecate.
(http-head, http-post, http-put, http-delete, http-trace)
(http-options): Define interfaces for all HTTP verbs.
* test-suite/tests/web-client.test: Add tests.
* doc/ref/web.texi: Update documentation.
Thanks to Gregory Benison for the initial patch.
* module/web/response.scm (read-response-body): Fix to always return
either a bytevector or #f. Previously, reading a 0-length body could
return the EOF object.
* module/ice-9/slib.scm: Change to just load up slib.init directly. The
recently submitted patch to slib-discuss and guile-user should make
this work correctly.
* libguile/__scm.h:
* libguile/deprecated.h (SCM_CHAR_CODE_LIMIT): Move declaration here
from __scm.h.
* libguile/feature.c:
* module/ice-9/deprecated.scm (char-code-limit): Move definition here.
* test-suite/tests/regexp.test: Update to not use char-code-limit.
* libguile/posix.c (scm_open_process): Return the ports as values
instead of calling out to Scheme again to make-rw-port. This
function is private to (ice-9 popen).
* module/ice-9/popen.scm (open-pipe*): Adapt to change.
* module/web/http.scm ("Connection"): Write the "close" token in
lower-case.
* module/web/client.scm (http-get): Don't shutdown the writing side of
the pipe if we are not doing a keepalive, as this may prevent the
request from being sent at all. Prevented http://friendfeed.com/ from
being correctly fetched.
* doc/ref/api-procedures.texi (Compiled Procedures): Expand
program-arguments-alist and program-lambda-list documentation.
* module/system/vm/program.scm (arity->arguments-alist): Fix the rest
arg if there are also keyword args, a bug found while documenting!
* test-suite/tests/session.test ("procedure-arguments"): Update.
* check/cccall.c, check/ccall.ok: New test case to validate
interleaved calls from/to C code and jit.
* check/Makefile.am: Update for the new ccall test case.
* include/lightning.h, lib/lightning.c: Add the new jit_address
call that returns the real/final address of a "note" in the
generated jit. It requires a jit_node_t as returned by the
jit_note call, and is only valid after calling jit_emit.
Add an intermediate solution to properly handle arm
soft and softfp modes that move a double to an integer register
pair. Currently it just adds extra tests for the condition,
but the proper solution should be to have extra lightning
codes for these conditions, codes which should be only used
by the backends that need it, and merged with the existing
jit_pusharg*_{f,d}.
* include/lightning/jit_private.h: Add new jit_state_t flag
to know it finished jit_emit, so that calls to jit_address
are valid.
* lib/jit_mips.c: Correct abi implementation so that the
new ccall test case pass. Major problem was using
_jit->function.self.arg{i,f} as boolean values, but that
would cause lightning.c:patch_registers() to incorrectly
assume only one register was used as argument when calling
jit_regarg_p(); _jit->function.self.arg{i,f} must be the
number of registers used as arguments (in all backends).
* lib/jit_x86.c: Add workaround, by marking %rax as used,
to a special condition, when running out of registers and the
allocator trying to spill and reload %rax, but %rax was used
as a pointer to a function, what would cause the reload to
destroy the return value. This condition can be better
generalized, but the current solution is good enough.
* include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
Rewrite logic to handle arguments, as the original code was
written based on a SysV pdf about the generic powerpc ABI,
what did "invent" a new abi for the previous test cases, but
failed in the new ccall test in Darwin PPC. Now it properly
handles 13 float registers for arguments, as well as proper
computation of stack offsets when running out of registers
for arguments.
* lib/lightning.c: Correct both, wrong and confusing logic
to compute the reverse of a jump. Now it properly matches
C semantics for "eq" (==) and "ne" (!=) and correct computation
of reverse of "uneq" as "gt".
* check/branch.tst: Update "ne" float branch check that
previously happened to be wrongly tested with a NaN argument.
* check/float.ok, check/float.tst: New test cases implementing
extensive validation of float comparison and branch code
generation as well as integer conversion, involving NaN and
[+-]Inf.
* lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
Correct bugs found by new float test case.
* lib/jit_x86.c: Correct cut&paste error added in commit to
convert jit_arg* return value to a jit_node_t*, that would
cause it to not properly handle double arguments in ix86.
* check/Makefile.am: Update for the new test case.
* check/lightning.c, include/lightning.h, lib/jit_arm.c,
lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c,
lib/lightning.c: Change return value of jit_arg{,_f,_d} to
a jit_node_t* object, that should be used as argument to
jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
for the getarg calls, with the benefit that it makes it easy
to implement patching of the stack address of non register
arguments, this way allowing to implement variable size stack
frames if applicable; useful if there are too many registers and
jit functions uses only a few callee save registers.
* lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct
regressions when patching jit_calli for a forward function.
* lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode
in jit_getarg_u{c,s} implementation.
* check/call.ok, check/call.tst: New test cases to validate
simple typed argument and return values in function calls.
* check/lightning.c: Properly handle jit_movi of labels for
backward and forward code labels.
* check/Makefile.am: Update for new test case.
* lib/jit_arm.c: Correct use of wrong argument offset
variable in armv7l or float/double argument for varargs
function in armv7hl.
Correct jit_getarg* logic in software float mode to
match expected behavior in other backends, that is, if
a function is not called, it is safe to use a few lightning
calls before a next jit_getarg* call, as done in the test
case check/stack.tst. The proper solution should be to
extend the parser in lib/lightning.c to check if there is
some float operation that will call some (libgcc?) function,
but software float arm should be a very uncommon backend for
lightning, so, just load the already in place arguments
saved to stack, assuming the register argument was clobbered
(what should not be the case most times...).
* check/clobber.ok, check/clobber.tst: New test case doing
extensive validation tests to ensure registers not used in
a operation are not clobbered.
* check/Makefile.am: Update for new test case.
* lib/lightning.c: Partially rewrite/revert code to compute
initial register live state at the start of a basic block.
The original logic was corrupted when adding optimizations
to do as few computations as possible in jit_update. The
reglive field must be always a known set of live registers
at the start of a basic block. The value that was incorrect
was the regmask field, that must be the set of registers
that are in unknown state, because they are not known live,
neither set (or possibly not set) in the basic block, and
*must* store the state at the start of the basic block.
* include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5}
with enum codes, that were correct, and returned by jit_f().
* lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly
implement and better describe values when generating stack
frames.
Fixes <http://bugs.gnu.org/13166>.
* libguile/simpos.c (scm_system_star): In the child, call `_exit'
instead of `SCM_SYSERROR' when `execvp' fails.
* test-suite/tests/posix.test ("system*"): New test prefix.
* check/stack.ok, check/stack.tst: New files to test data
integrity on a deep chain of stack frames.
* lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
in the emit stage, otherwise it will calculate it wrong if
need to jit_allocai space to spill registers.
* lib/lightning.c: Correct wrong offset when updating the
"current" jit function pointer in the code that may need to
allocate stack space to spill registers.
* check/lightning.c: Correct off by one data space check.
* check/Makefile.am: Update for new test case.
* check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok,
check/fop_sqrt.tst: New files implementing simple test cases
for the extra float operations.
* check/Makefile.am: Update for new test cases.
* check/alu.inc: Add an extra macro to check for unordered
equality on tests where it is expected to use NaN as an
argument.
* check/lightning.c: Minor change for proper/common argument
syntax handling ommiting arguments to options.
* check/Makefile.am: Automatically generate pattern list
of tests with alternate jit generation options. This should
prevent typos and needing to change multiple places after
a change.
* module/web/client.scm (open-socket-for-uri): Delete addrinfos
with the same address. Always open SOCK_STREAM/IPPROTO_IP sockets.
Fix the error handler's condition to determine what to do.
Reported by Nikita Karetnikov <nikita.karetnikov@gmail.com> at
<http://lists.gnu.org/archive/html/bug-guix/2012-12/msg00150.html>.
* check/lightning.c: Remove the ".cpu name value" syntax,
as it was not able to do proper changes before the jit
internal data structure was initialized. Now it supports
several getopt options to force using different jit
generation options, effectively replacing the previous
syntax.
* check/run-test: Add simple extra logic to handle differently
named test scripts, used to test things like x87 coprocessor
in ix86, and arm instruction set or software float in armv7l.
* configure.ac: Add some AC_RUN_IFELSE calls to figure at
compile time if can test different code generation options,
and update Makefile generation accordingly.
* check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to
properly work with the test tool updating the jit_cpu global
information.
* check/check.arm.sh, check/check.swf.sh, check/check.x87.sh:
New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to
the test tool, if applicable, so that it can validate alternate
code generation options on test hosts that support them.
* include/lightning.h, include/lightning/jit_private.h,
lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
lib/lightning.c: Make jit_ellipsis implementation not
backend specific. It is not intended to handle va_list
like objects at runtime, as jit_arg* and jit_getarg*
return constant values resolved at parse time, so, effectively
it is not possible to create printf like jit functions, as
there is no va_start, va_arg, va_end, etc, abstraction. This
limitation should be kept for the sake of making new ports
easier.
* include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
to no longer receive an argument. If receiving an argument, it
should be an ABI specifier, not a boolean if varargs or not,
and add the new jit_ellipsis call, to specify where the
ellipsis is in the C prototype of the function being called.
Note that currently it is not supported to define varargs
functions and it will be ignored if calling jit_ellipsis not
in a prepare/finish* block, but this should be addressed.
* check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,
check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst,

check/ldstr.tst, check/ldstxi-c.tst, check/ldstxi.tst,
check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst,
check/lightning.c: Update for the change to jit_prepare and
addition of jit_ellipsis.
* lib/jit_ppc-cpu.c: Make movr a function that checks arguments
so that other code can safely assume it is a noop if src and dst
are the same register.
Implement rem{r,i}{,_u} as a div{,u}/mul/sub.
Correct ANDIS, ORIS and XORIS calls to cast the argument to
unsigned before the shift to avoid an assertion if the argument
had the topmost bit set.
Implement lshi, rshi and rshi_u as functions to test for a
zero argument, that would otherwise trigger an assertion when
computing the shift value.
Do a simple implementation of bm{s,c}{r,i} with a temporary,
"andr" of arguments and jump based on comparison with zero.
Correct typo in ldxi_c.
* lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*.
* lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer
arguments in registers. If calling a varargs function and
passing a float or double argument, also either store the
value in the stack or in integer registers, as varargs functions
do not fetch it from float registers.
Add "case" for new functions and incorrectly missing ones.
Call libgcc's __clear_cache, that should know what to do
if the hardware needs flushing cache before execution.
* lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1,
that should make it easier for the compiler to optimize it, and
that also corrects the previously wrong code for big endian, and
that was causing problems in ppc due to not saving all callee save
registers as it was not "finding" them in the regset due to the
little endian assumption bug.
* configure.ac: Only default to using the builtin disassembler
if on GNU/Linux. This should be temporary, due to requiring
/proc/self/exe.
Correctly check $target_cpu for powerpc.
* include/lightning/jit_ppc.h: Correctly implement jit_v_num.
* include/lightning/jit_private.h: Declare proper prototype
for jit_init_debug and jit_finish_debug.
* lib/jit_ppc-cpu.c: Remove code to save/restore callee save
float registers, as it is not required since those float
registers are not usable currently.
Change prolog and epilog generation to, at least comparing
code, match what gcc generates in "gcc -O0", but it is still
failing in Darwin PPC, apparently due to the __clear_cache
call not being enough, as frequently it will also fail to
execute, and the code buffer is all zeroes.
* lib/lightning.c: Do not fail in jit_regset_scan1 calls due
to passing 64 as argument on computers with 64 registers.
* lib/jit_mips-cpu.c: Correct all current test cases.
Call the "xori" not the "XORI" macro for jit_xori implementation,
as the XORI macro handles only 16 bit unsigned values.
Call the "movr" macro, not the "movi" macro in the special
case of adding or subtracting zero.
Use the proper temporary register in the jit_andr implementation.
* check/alu.inc, check/alu_add.ok, check/alu_add.tst,
check/alu_and.ok, check/alu_and.tst, check/alu_com.ok,
check/alu_com.tst, check/alu_div.ok, check/alu_div.tst,

check/alu_xor.tst, check/alux_add.ok, check/alux_add.tst,
check/alux_sub.ok, check/alux_sub.tst, check/branch.ok,
check/branch.tst: New test cases for arithmetic and branch
tests.
* check/Makefile.am: Update for new test cases.
* include/lightning/jit_private.h: Make the jit_reg_free_p
macro shared by all backends. Previously was added for the
arm backend, but is useful in the x86_64 backend when checking
state of "special purpose register".
Also add the new jit_class_named register class, that must be
or'ed with the register value if calling jit_get_reg expecting
an specific value, because the specific register value may be
zero, that previously was treated as no register requested.
* lib/jit_arm-cpu.c: Correct argument order for T2_MVN.
* lib/jit_arm-swf.c: Call the proper function for double
divide. The "software float" implementation just calls
libgcc functions.
* lib/jit_arm.c: Return float/double values in the float
register if using the hard float ABI.
* lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro
to not include -0x80000000L, because there is code that
"abuses" it and thinks it can negate the immediate value
after calling that macro.
Correct implementation of jit_subi that had a wrong code
patch logic doing subtraction with reversed arguments.
Correct REX prefix calculation in the jit_muli implementation.
Correct logic to get/unget %*ax and %*dx registers in divremr
and divremi.
Correct divremi that was using the symbolic, unique %*ax
value in on place (not using the _REGNO name suffix).
Correct cut&paste error causing it to use "xor" instead of
"or" in one code path of the jit_ori implementation.
Correct several flaws when clobbering registers and/or when
one of the arguments was %*cx in the rotshr wrapper function
implementing most shift operations.
* lib/lightning.c: No longer expect that the backend be smart
enough to know what to do when asking for a named register
if that register is already an argument or is live. It fails
if it is an argument, or if register is live, fails if cannot
spill.
No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are
safe to inverse value tests in jump thread optimization.
