gnu-maintenance: Relax recursion cutoff in 'latest-ftp-release'. Fixes <https://bugs.gnu.org/25020>. Reported by Hartmut Goebel <h.goebel@crazy-compilers.com>. * guix/gnu-maintenance.scm (latest-ftp-release)[contains-digit?]: Remove. Relax test as to whether to recurse into subdirectories.
ui: 'known-variable-definition' protects against module cycles. Fixes <https://bugs.gnu.org/29358>. Reported by Marius Bakke <mbakke@fastmail.com>. * guix/ui.scm (known-variable-definition): Add 'visited' set to guard against cycles on 2.0.
Revert "Add (guix self) and use it when pulling." This reverts commit 5f93d97005897c2d859f0be1bdff34c88467ec61. 'guix pull' would fail because (guix self) needs 'scheme-files' from (guix discovery), which was not exported until now.
Add (guix self) and use it when pulling. This mitigates <https://bugs.gnu.org/27284>. * guix/self.scm: New file. * Makefile.am (MODULES): Add it. * build-aux/build-self.scm (libgcrypt, zlib, gzip, bzip2, xz) (false-if-wrong-guile, package-for-current-guile, guile-json) (guile-ssh, guile-git, guile-bytestructures): Remove. (build): Rewrite to simply delegate to 'compiled-guix'. * gnu/packages.scm (%distro-root-directory): Rewrite to try different directories. * guix/discovery.scm (guix): Export 'scheme-files'. * guix/scripts/pull.scm (build-and-install): Split into... (install-latest): ... this. New procedure. And... (build-and-install): ... this, which now takes a monadic value argument. (indirect-root-added): Remove. (guix-pull): Call 'add-indirect-root'. Call 'build-from-source' and pass the result to 'build-and-install'.
git: Do not add '.git' to the store. This makes 'latest-repository-commit' significantly more efficient and reduces disk usage in the store. * guix/git.scm (copy-to-store)[dot-git?]: New procedure. Pass it as the #:select? argument to 'add-to-store'.
pull: Trim import list. * guix/scripts/pull.scm: Remove useless imports.
gexp: 'directory-union' has a #:quiet? parameter. * guix/gexp.scm (directory-union): Add #:quiet? and honor it.
union: Parametrize the symlink procedure . * guix/gexp.scm (directory-union): Add #:hard-links and honor it. * guix/build/union.scm (union-build): Add #:symlink parameter.
compile: Put an upper bound on the number of workers. * guix/build/compile.scm (compile-files): Don't use more than 8 workers.
Add semicolon in commands that set GUIX_PROFILE. Fixes <https://bugs.gnu.org/28223>. Reported by Rosebud Uplink <Uplink.Introversion@outlook.com>. * doc/guix.texi (Binary Installation): Add missing semicolon after 'GUIX_PROFILE=' line. (Invoking guix package): Likewise. * gnu/system.scm (operating-system-etc-service)[profile]: Likewise. * guix/build/profiles.scm (build-etc/profile): Likewise.
zlib: Fix race condition when closing gzip ports. Fixes <https://bugs.gnu.org/29335>. * guix/zlib.scm (close-procedure): Remove. (make-gzip-input-port): Do (dup (fileno port)) to get a file descriptor for 'gzdopen'. Close PORT before returning. Use 'gzclose' as the 'close' procedure of the returned port. (make-gzip-output-port): Likewise.
ssh: Use (guix i18n). * guix/ssh.scm: Use (guix i18n) instead of (guix ui).
licenses: Add cddl1.1. * guix/licenses.scm (cddl1.1): New variable.
build-system: texlive: Only make a union of directories. * guix/build/texlive-build-system.scm (configure): Filter the input directories to ensure that source tarballs are excluded.
build-system/go: Don't let Go executables refer to the Go compiler. * guix/build/go-build-system.scm (remove-store-reference, remove-go-references): New procedures. (%standard-phases): Add 'remove-go-references' phase. * guix/build-system/go.scm (go-build): Add allow-go-reference? key.
workers: Display backtrace in pre-unwind handler. * guix/workers.scm (worker-thunk): Add (const #f) as the 'catch' handler, and move previous handler as pre-unwind handler. Protect against 'make-stack' returning #f.
workers: 'pool-idle?' returns true only if the workers are idle. Fixes <https://bugs.gnu.org/28779>. Reported by Eric Bavier <bavier@cray.com>. * guix/workers.scm (<pool>)[busy]: New field. (worker-thunk): Add #:idle and #:busy and use them. (make-pool): Pass #:busy and #:idle to 'worker-thunk'. Pass a 'busy' value to '%make-pool'. * guix/workers.scm (pool-idle?): Check whether 'pool-busy' returns zero and adjust docstring.
ui: Add source file name to the package search metrics. * guix/ui.scm (%package-metrics): Include 'package-location'. Increase score of the other fields.
cve: Use 'http-fetch/cached' instead of having custom caching. That way CVE fetching benefits from 'If-Modified-Since' handling. * guix/http-client.scm (http-fetch/cached): Add #:write-cache and #:cache-miss parameters and honor them. * guix/cve.scm (%current-year-ttl, %past-year-ttl): Reduce. (call-with-cve-port): Remove. (write-cache): New procedure. (fetch-vulnerabilities): Rewrite in terms of 'http-fetch/cached'.
download: Improve efficiency of 'write-request' over TLS. This is another instance of <https://bugs.gnu.org/22966>. The Microsoft-IIS/7.5 server at static.nvd.nist.gov would sometimes hang when receiving our requests byte by byte. * guix/build/download.scm (tls-wrap) [!guile-2.0]: Add 'setvbuf' call.
