commit 175955725e1ba58a591bd07123dd60700a8ccd20
Author: Andy Wingo <address@hidden>
Date: Thu Oct 27 14:09:47 2011 +0200
fix the peval merge and a test
* module/language/tree-il/peval.scm (peval): Accessor primitives applied
to constants are pure if the call type-checks. Also, fold constants
in accessor primcalls.
* test-suite/tests/tree-il.test ("partial evaluation"): Fix the "yo"
test.

Please send Guile bug reports to address@hidden
+Changes in 2.0.3 (since 2.0.2):
+
+* Speed improvements
+
+** Guile has a new optimizer, `peval'.
+
+`Peval' is a partial evaluator that performs constant folding, dead code
+elimination, copy propagation, and inlining. By default it runs on
+every piece of code that Guile compiles, to fold computations that can
+happen at compile-time, so they don't have to happen at runtime.
+
+If we did our job right, the only impact you would see would be your
+programs getting faster. But if you notice slowdowns or bloated code,
+please send a mail to address@hidden with details.
+
+Thanks to William R. Cook, Oscar Waddell, and Kent Dybvig for inspiring
+peval and its implementation.
+
+You can see what peval does on a given piece of code by running the new
+`,optimize' REPL meta-command, and comparing it to the output of
+`,expand'. See "Compile Commands" in the manual, for more.
+
+** Fewer calls to `stat'.
+
+Guile now stats only the .go file and the .scm file when loading a fresh
+compiled file.
+
+* Notable changes
+
+** New module: `(web client)', a simple synchronous web client.
+
+See "Web Client" in the manual, for more.
+
+** Users can now install compiled `.go' files.
+
+See "Installing Site Packages" in the manual.
+
+** Remove Front-Cover and Back-Cover text from the manual.
+
+The manual is still under the GNU Free Documentation License, but no
+longer has any invariant sections.
+
+** More helpful `guild help'.
+
+`guild' is Guile's multi-tool, for use in shell scripting. Now it has a
+nicer interface for querying the set of existing commands, and getting
+help on those commands. Try it out and see!
+
+** New macro: `define-syntax-rule'
+
+`define-syntax-rule' is a shorthand to make a `syntax-rules' macro with
+one clause. See "Syntax Rules" in the manual, for more.
+
+** The `,time' REPL meta-command now has more precision.
+
+The output of this command now has microsecond precision, instead of
+10-millisecond precision.
+
+** `(ice-9 match)' can now match records.
+
+See "Pattern Matching" in the manual, for more on matching records.
+
+** New module: `(language tree-il debug)'.
+
+This module provides a tree-il verifier. This is useful for people that
+generate tree-il, usually as part of a language compiler.
+
+** New functions: `scm_is_exact', `scm_is_inexact'.
+
+These provide a nice C interface for Scheme's `exact?' and `inexact?',
+respectively.
+
+* Bugs fixed
+
+See the git log (or the ChangeLog) for more details on these bugs.
+
+** Fix order of importing modules and resolving duplicates handlers.
+** Fix a number of bugs involving extended (merged) generics.
+** Fix invocation of merge-generics duplicate handler.
+** Fix write beyond array end in arrays.c.
+** Fix read beyond end of hashtable size array in hashtab.c.
+** (web http): Locale-independent parsing and serialization of dates.
+** Ensure presence of Host header in HTTP/1.1 requests.
+** Fix take-right and drop-right for improper lists.
+** Fix leak in get_current_locale().
+** Fix recursive define-inlinable expansions.
+** Check that srfi-1 procedure arguments are procedures.
+** Fix r6rs `map' for multiple returns.
+** Fix scm_tmpfile leak on POSIX platforms.
+** Fix a couple of leaks (objcode->bytecode, make-boot-program).
+** Fix guile-lib back-compatibility for module-stexi-documentation.
+** Fix --listen option to allow other ports.
+** Fix scm_to_latin1_stringn for substrings.
+** Fix compilation of untyped arrays of rank not 1.
+** Fix unparse-tree-il of <dynset>.
+** Fix reading of #||||#.
+** Fix segfault in GOOPS when class fields are redefined.
+** Prefer poll(2) over select(2) to allow file descriptors above FD_SETSIZE.
+

address@hidden inlining
address@hidden procedure inlining
You can define an @dfn{inlinable procedure} by using
@code{define-inlinable} instead of @code{define}. An inlinable
procedure behaves the same as a regular procedure, but direct calls will
result in the procedure body being inlined into the caller.
address@hidden partial evaluator
+Bear in mind that starting from version 2.0.3, Guile has a partial
+evaluator that can inline the body of inner procedures when deemed
+appropriate:
+
address@hidden
+scheme@@(guile-user)> ,optimize (define (foo x)
+ (define (bar) (+ x 3))
+ (* (bar) 2))
+$1 = (define foo
+ (lambda (address@hidden address@hidden) (* (+ address@hidden
address@hidden 3) 2)))
address@hidden example
+
address@hidden
+The partial evaluator does not inline top-level bindings, though, so
+this is a situation where you may find it interesting to use
address@hidden
+
Procedures defined with @code{define-inlinable} are @emph{always}
inlined, at all direct call sites. This eliminates function call
overhead at the expense of an increase in code size. Additionally, the

address@hidden Autoconf Background
address@hidden Autoconf Background
-
-As explained in the @cite{GNU Autoconf Manual}, any package needs
-configuration at build-time (@pxref{Top, ,Introduction,autoconf,The GNU
-Autoconf Manual}). If your package uses Guile (or uses a package that
-in turn uses Guile), you probably need to know what specific Guile
-features are available and details about them.
-
-The way to do this is to write feature tests and arrange for their execution
-by the @file{configure} script, typically by adding the tests to
address@hidden, and running @code{autoconf} to create @file{configure}.
-Users of your package then run @file{configure} in the normal way.
-
-Macros are a way to make common feature tests easy to express.
-Autoconf provides a wide range of macros
-(@pxref{Existing Tests,,,autoconf,The GNU Autoconf Manual}),
-and Guile installation provides Guile-specific tests in the areas of:
-program detection, compilation flags reporting, and Scheme module
-checks.

address@hidden autoconf
-
-GNU Guile provides a @dfn{pkg-config} description file, which contains
-all the information necessary to compile and link C applications that
-use Guile. The @code{pkg-config} program is able to read this file
-and provide this information to application programmers; it can be
-obtained at @url{http://pkg-config.freedesktop.org/}.
-
-The following command lines give respectively the C compilation and link
-flags needed to build Guile-using programs:
-
address@hidden
-pkg-config address@hidden --cflags
-pkg-config address@hidden --libs
address@hidden example
-
-To ease use of pkg-config with Autoconf, pkg-config comes with a
-convenient Autoconf macro. The following example looks for Guile and
-sets the @code{GUILE_CFLAGS} and @code{GUILE_LIBS} variables
-accordingly, or prints an error and exits if Guile was not found:
-
address@hidden PKG_CHECK_MODULES
-
address@hidden
-PKG_CHECK_MODULES([GUILE], address@hidden)
address@hidden example
-
-Guile comes with additional Autoconf macros providing more information,
-installed as @address@hidden/share/aclocal/guile.m4}. Their names
-all begin with @code{GUILE_}.
-
address@hidden see Makefile.am
address@hidden autoconf-macros.texi
-
-
address@hidden Using Autoconf Macros
address@hidden Using Autoconf Macros
-
-Using the autoconf macros is straightforward: Add the macro "calls" (actually
-instantiations) to @file{configure.ac}, run @code{aclocal}, and finally,
-run @code{autoconf}. If your system doesn't have guile.m4 installed, place
-the desired macro definitions (@code{AC_DEFUN} forms) in @file{acinclude.m4},
-and @code{aclocal} will do the right thing.
-
-Some of the macros can be used inside normal shell constructs: @code{if foo ;
-then GUILE_BAZ ; fi}, but this is not guaranteed. It's probably a good idea
-to instantiate macros at top-level.
-
-We now include two examples, one simple and one complicated.
-
-The first example is for a package that uses libguile, and thus needs to
-know how to compile and link against it. So we use
address@hidden to set the vars @code{GUILE_CFLAGS} and
address@hidden, which are automatically substituted in the Makefile.

address@hidden example
-
-The second example is for a package of Guile Scheme modules that uses an
-external program and other Guile Scheme modules (some might call this a "pure

address@hidden Autofrisk
address@hidden Autofrisk
-
-The @dfn{guild autofrisk} command looks for the file @file{modules.af}
-in the current directory and writes out @file{modules.af.m4} containing
-autoconf definitions for @code{AUTOFRISK_CHECKS} and
address@hidden @xref{Autoconf Background}, and @xref{Using
-Autoconf Macros}, for more info.
-
-The modules.af file consists of a series of configuration forms (Scheme
-lists), which have one of the following formats:
-
address@hidden
- (files-glob PATTERN ...) ;; required
- (non-critical-external MODULE ...) ;; optional
- (non-critical-internal MODULE ...) ;; optional
- (programs (MODULE PROG ...) ...) ;; optional
- (pww-varname VARNAME) ;; optional
address@hidden example
-
address@hidden is a string that may contain "*" and "?" characters to be
-expanded into filenames. @var{module} is a list of symbols naming a module,
-such as `(srfi srfi-1)'. @var{varname} is a shell-safe name to use instead of
address@hidden, the default. This var is passed to `AC_SUBST'.
address@hidden is a string that names a program, such as "gpg".
-
-Autofrisk expands the @code{files-glob} pattern(s) into a list of files, scans
-each file's module definition form(s), and constructs a module dependency
-graph wherein modules defined by @code{define-module} are considered
address@hidden and the remaining, @dfn{external}. For each external module
-that has an internal dependency, Autofrisk emits a
address@hidden check (@pxref{Autoconf Macros}), which altogether
-form the body of @code{AUTOFRISK_CHECKS}.
-
address@hidden causes the @file{configure} script to exit with
-an error message if the specified module is not available; it enforces a
-strong dependency. You can temper dependency strength by using the
address@hidden and @code{non-critical-internal} configuration
-forms in modules.af. For graph edges that touch such non-critical modules,
-Autofrisk uses @code{GUILE_MODULE_AVAILABLE}, and arranges for
address@hidden to display a warning if they are not found.
-
-The shell code resulting from the expansion of @code{AUTOFRISK_CHECKS} and
address@hidden uses the shell variable @code{probably_wont_work} to
-collect the names of unfound non-critical modules. If this bothers you, use
-configuration form @code{(pww-name foo)} in modules.af.
-
-Although Autofrisk does not detect when a module uses a program (for example,
-in a @code{system} call), it can generate @code{AC_PATH_PROG} forms anyway if
-you use the @code{programs} configuration form in modules.af. These are
-collected into @code{AUTOCONF_CHECKS}.
-
address@hidden Autofrisk}, for some modules.af examples.
-
-
address@hidden Using Autofrisk
address@hidden Using Autofrisk
-
-Using Autofrisk (@pxref{Autofrisk}) involves writing @file{modules.af} and
-adding two macro calls to @file{configure.in}. Here is an example of the
-latter:
-
address@hidden
-AUTOFRISK_CHECKS
-AUTOFRISK_SUMMARY
address@hidden example
-
-Here is an adaptation of the second "GUILE_*" example (@pxref{Using Autoconf
-Macros}) that does basically the same thing.
-
address@hidden
-(files-glob "my/*.scm")
-(non-critical-external (database postgres))
-(programs ((my gpgutils) "gpg")) ;; (my gpgutils) uses "gpg"
address@hidden example
-
-If the SRFI modules (@pxref{SRFI Support}) were a separate package, we could
-use @code{guild frisk} to find out its dependencies:
-
address@hidden
-$ guild frisk srfi/*.scm
-13 files, 18 modules (13 internal, 5 external), 9 edges
-
-x (ice-9 and-let-star)
- regular (srfi srfi-2)
-x (ice-9 syncase)
- regular (srfi srfi-11)
-x (ice-9 rdelim)
- regular (srfi srfi-10)
-x (ice-9 receive)
- regular (srfi srfi-8)
- regular (srfi srfi-1)
-x (ice-9 session)
- regular (srfi srfi-1)
address@hidden example
-
-Then, we could use the following modules.af to help configure it:
-
address@hidden
-(files-glob "srfi/*.scm")
-(non-critical-external ;; relatively recent
- (ice-9 rdelim)
- (ice-9 receive)
- (ice-9 and-let-star))
-(pww-varname not_fully_supported)

+Guile provides strong API and ABI stability guarantees during stable
+series, so that if a user writes a program against Guile version 2.0.3,
+it will be compatible with some future version 2.0.7. We say in this
+case that 2.0 is the @dfn{effective version}, composed of the major and
+minor versions, in this case 2 and 0.
+
+Users may install multiple effective versions of Guile, with each
+version's headers, libraries, and Scheme files under their own
+directories. This provides the necessary stability guarantee for users,
+while also allowing Guile developers to evolve the language and its
+implementation.
+
+However, parallel installability does have a down-side, in that users
+need to know which version of Guile to ask for, when they build against
+Guile. Guile solves this problem by installing a file to be read by the
address@hidden utility, a tool to query installed packages by name.
+Guile encodes the version into its pkg-config name, so that users can
+ask for @code{guile-2.0} or @code{guile-2.2}, as appropriate.
+
+For effective version @value{EFFECTIVE-VERSION}, for example, you would

+people. To do so effectively, it is important to follow a set of common
+conventions, to make it easy for the user to install and use your
+package.
+
+The first thing to do is to install your Scheme files where Guile can
+find them. When Guile goes to find a Scheme file, it will search a
address@hidden path} to find the file: first in Guile's own path, then in
+paths for @dfn{site packages}. A site package is any Scheme code that
+is installed and not part of Guile itself. @xref{Loading}, for more on
+load paths.
+
+There are several site paths, for historical reasons, but the one that
+should generally be used can be obtained by invoking the
address@hidden procedure. @xref{Build Config}. If Guile
address@hidden is installed on your system in @code{/usr/},
+then @code{(%site-dir)} will be
address@hidden/usr/share/guile/site/@value{EFFECTIVE-VERSION}}. Scheme files
+should be installed there.
+
+If you do not install compiled @code{.go} files, Guile will compile your
+modules and programs when they are first used, and cache them in the
+user's home directory. @xref{Compilation}, for more on
+auto-compilation. However, it is better to compile the files before
+they are installed, and to just copy the files to a place that Guile can
+find them.
+
+As with Scheme files, Guile searches a path to find compiled @code{.go}
+files, the @code{%load-compiled-path}. By default, this path has two
+entries: a path for Guile's files, and a path for site packages. You
+should install your @code{.go} files into the latter. Currently there
+is no procedure to get at this path, which is probably a bug. As in the
+previous example, if Guile @value{EFFECTIVE-VERSION} is installed on
+your system in @code{/usr/}, then the place to put compiled files for
+site packages will be
address@hidden/usr/lib/guile/@value{EFFECTIVE-VERSION}/site-ccache}.
+
+Note that a @code{.go} file will only be loaded in preference to a
address@hidden file if it is newer. For that reason, you should install
+your Scheme files first, and your compiled files second.
+
+Finally, although this section is only about Scheme, sometimes you need
+to install C extensions too. Shared libraries should be installed in
+the @dfn{extensions dir}. This value can be had from the build config
+(@pxref{Build Config}). Again, if Guile @value{EFFECTIVE-VERSION} is
+installed on your system in @code{/usr/}, then the extensions dir will
+be @code{/usr/lib/guile/@value{EFFECTIVE-VERSION}/extensions}.

+If @var{decode-body?} is true, as is the default, the body of the
+response will be decoded to string, if it is a textual content-type.
+Otherwise it will be returned as a bytevector.
address@hidden deffn
+
address@hidden is useful for making one-off requests to web sites. If
+you are writing a web spider or some other client that needs to handle a
+number of requests in parallel, it's better to build an event-driven URL
+fetcher, similar in structure to the web server (@pxref{Web Server}).
+
+Another option, good but not as performant, would be to use threads,
+possibly via par-map or futures.
+
+More helper procedures for the other common HTTP verbs would be a good
+addition to this module. Send your code to
address@hidden@@gnu.org}.
