FIXME Apply this patch only when compiling for mingw.
Temporary hack until we have a proper fix to determine
compile-time-file-name-convention
* module/ice-9/boot-9.scm (compile-time-file-name-convention): Hardcode
to 'mingw instead of 'posix.
On MinGW, port-read will block on sockets if no data is available.
Avoid blocking by using select first.
* module/ice-9/suspendable-ports.scm (read-bytes): For socket ports,
guard port-read with select.
* module/ice-9/boot-9.scm (compile-time-file-name-convention): New
procedure, defined only when loading.
(compile-time-case): Use it to correctly determine system file name
convention while compiling.
This makes the docstring attached to the curried function being defined
rather than the result of its application until a function that runs the
body is obtained, fixing

Guile (3.0.8) reports a compilation error when cond-expand tries to
check existence of a missing library:
scheme@(guile-user)> (define-library (test)
(cond-expand
((library (scheme sort))
(import (scheme sort)))))
While compiling expression:
no code for module (scheme sort)
It looks like bug #40252 was not fully eliminated.
Also, (library ...) cannot handle module names like (srfi 1), though
(import (srfi 1)) works fine. For example, this code fails:
scheme@(guile-user)> (define-library (test)
(cond-expand
((library (srfi 1))
(import (srfi 1)))))
While compiling expression:
In procedure symbol->string: Wrong type argument in position 1
(expecting symbol): 1
There are probably other cases when (library ...) and (import ...) does
not work identically: (library ...) uses resolve-interface while
(import ...) uses resolve-r6rs-interface.
This patch fixes both issues.
* module/ice-9/r7rs-libraries.scm (define-library): Replace
'resolve-interface' call by 'resolve-r6rs-interface', wrapped in
'cond-expand'.

Commit 54bbe0b284 inadvertently led
psyntax to dismiss source location info for data returned by read hash
extensions, because read hash extensions return plain data with
associated source properties, even when called from 'read-syntax'.
This change reverts part of this commit to restore that behavior.
Fixes <https://issues.guix.gnu.org/54003>.
* module/ice-9/psyntax.scm (datum-sourcev): New procedure.
(source-annotation): Fall back to 'datum-sourcev'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* test-suite/tests/compiler.test ("psyntax")["syntax-source with
read-hash-extend"]: New test.
Avoiding systematic conversion from source vectors to property alists
saves 20% on the final heap size of a process doing:
(compile-file FILE #:optimization-level 1)
where FILE is large.
* module/language/tree-il.scm (tree-il-src/ensure-alist): New procedure
with setter. Export as 'tree-il-src'.
* module/ice-9/psyntax.scm (build-void, build-call)
(build-conditional, build-lexical-reference, build-lexical-assignment)
(build-global-reference, build-global-assignment)
(build-global-definition, build-simple-lambda, build-case-lambda)
(build-lambda-case, build-primcall, build-primref)
(build-data, build-sequence, build-let, build-named-let)
(build-letrec, expand-body): Remove (sourcev->alist src) calls.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/language/tree-il/analyze.scm (shadowed-toplevel-analysis): Use
'tree-il-src' instead of accessing the 'src' slot directly.
* module/system/vm/assembler.scm (link-debug): Adjust so PC can be
followed by a vector or an alist.
* module/ice-9/psyntax.scm (source-annotation): Only return source
properties from syntax objects.
(source-wrap): Don't look for source properties.
(expand-macro): Rebuild source properties on macro output via
source-wrap, not source properties. Only annotate head of a chain of
pairs.
(strip): Here's the only use of set-source-properties!: when stripping
a syntax object to a datum.
(macroexpand): If the input expression is not a syntax object, eagerly
extract its source properties.
(datum->syntax): Fix case in which source is given as an alist.
* module/ice-9/psyntax-pp.scm: Regenerate.
Calling out to Scheme was a performance regression.
* libguile/integers.h:
* libguile/integers.c (scm_integer_expt_ii, scm_integer_expt_zi): New
internal functions.
* libguile/numbers.c (scm_integer_expt): Go back to C. But, include
fast cases for inums and doubles.
* module/ice-9/boot-9.scm: Revert addition of integer-expt.
* libguile/numbers.c (integer_expt_var): New static variable.
(init_integer_expt_var): New helper.
(scm_integer_expt): Delegate to Scheme.
* module/ice-9/boot-9.scm (integer-expt): Reimplement in Scheme. Misses
some optimizations for fractions but that is probably OK!

Partly fixes <https://bugs.gnu.org/40371>.
It was already possible to import an SRFI module by referencing it
as (srfi :n) which is automatically translated to (srfi srfi-n), but
this conversion was only done during import. After this change, it's
also possible to define a library as (srfi :n) which is automatically
translated to (srfi srfi-n) during definition.
It was not possible at all to define or import SRFI module names in the
R7RS format, (srfi n), where n is a non-negative exact integer. It is
now possible both to define and import them as such, realized through
the same kind of conversion to a canonical (srfi srfi-n) name.
* module/ice-9/r6rs-libraries.scm: Numerous changes.
* module/ice-9/match.upstream.scm (match-gen-ellipsis): Instead of just
binding the identifier when matching (x ...), go through match-one so
that if the id is already bound, we unify instead.
* test-suite/tests/match.test ("unify in list patterns"): Add test.
* test-suite/tests/match.test.upstream: Add additional tests from
upstream.
See commit 05c546e38 in Chibi Scheme. Thanks to Alex Shinn for help
here!
This is a regression since Guile 3.0.2 and breaks compilation
of a Guile library.
* module/ice-9/read.scm
(%read)[read-parenthesized]: When SAW-BRACE? is #t but CH isn't
#\#, don't eat CH.
* test-suite/tests/reader.test
("#{}#): Add four test cases.
In 3.0.7 (after 0cc7991855 "Ensure
that (syntax ()) results in ("), the use of #nil in syntax-rules
expansions like this:
(define-syntax foo
(syntax-rules ()
((_ x) (eq? #nil x))))
(foo #t)
could cause a crash that looks like this:
ice-9/psyntax.scm:2795:12: In procedure syntax-violation:
Syntax error:
unknown location: unexpected syntax in form ()
To fix it, add another special case (the commit mentioned above
special-cased the empty list) to preserve #nil
* module/ice-9/psyntax.scm (gen-syntax): Preserve #nil.
* test-suite/tests/syntax.test: Test #nil in syntax expansions.
Closes: 49305
* module/ice-9/r7rs-libraries.scm (define-library): Fix bug handling
include-library-declarations and cond-expand subforms. Thanks to Adam
Nelson for the fix! Fixes#40252.
* module/ice-9/psyntax.scm (syntax-violation): Pass source as an alist.
A sourcev would be better but it's incompatible.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/read.scm (%read): Add 1 to both line and column: the
former to make 1-based user lines instead of 0-based Guile lines, and
the latter because apparently that's how we always did it :) Fixes
* module/ice-9/boot-9.scm (duplicate-handlers): Use module-variable
instead of module-local-variable in the warn-override-core, first, and
last handlers. Fixes#47084 mostly, though relative to pre-3.0 there is
still a difference in that a module needs to explicitly declare which
bindings are intended as replacements -- a binding being a replacement
is a property of the module in 3.0, rather than the variable as was the
case before 3.0.
This reverts commit 0f983e3db0.
After discussing with Mike we are going to punt the read-line changes
for now. Open the port in O_TEXT mode if you want to chomp the CR in
CFLF sequences.
* libguile/rdelim.c (scm_read_line): handle CRLF, LS and PS
* module/ice-9/suspendable-ports.scm (read-line): handle CRLF, LS, and PS
* module/web/http.scm (read-header-line): take advantage of CRLF in read-line
(read-header): don't need to test for \return
* test-suite/tests/rdelim.test: new tests for read-line CRLF, LS and PS
* doc/ref/api-io.texi: update doc for read-line
* module/ice-9/read.scm (%read): Adjust how subexpressions are read to
error on EOF. Improve the error message.
* test-suite/tests/reader.test ("#;"): Adapt expectation.
