| 2019-03-17 | guix build: '--with-commit' makes recursive checkouts....This was an omission from commit
024a6bfba906742c136a47b4099f06880f1d3f15.
* guix/scripts/build.scm (transform-package-source-commit): Add
'recursive?' field to SOURCE.
* tests/scripts-build.scm ("options->transformation, with-branch")
("options->transformation, with-commit"): New tests.
| Ludovic Courtès |
| 2019-03-17 | guix build: Transformation options match packages by spec....This allows us to combine several transformations on a given package, in
particular '--with-git-url' and '--with-branch'.
Previously transformations would ignore each other since they would all
take (specification->package SOURCE) as their replacement source,
compare it by identity, which doesn't work if a previous transformation
has already changed SOURCE.
* guix/scripts/build.scm (evaluate-replacement-specs): Adjust to produce
an alist as expected by 'package-input-rewriting/spec', with a package
spec as the first element of each pair.
(evaluate-git-replacement-specs): Likewise.
(transform-package-inputs): Adjust accordingly and use
'package-input-rewriting/spec'.
(transform-package-inputs/graft): Likewise.
(transform-package-source-branch, transform-package-source-commit): Use
'package-input-rewriting/spec'.
(transform-package-source-git-url): Likewise, and adjust the
REPLACEMENTS alist accordingly.
(options->transformation): Iterate over OPTS instead of over
%TRANSFORMATIONS. Invoke transformations one by one.
* tests/scripts-build.scm ("options->transformation, with-input"):
Adjust test to compare packages by name rather than by identity.
("options->transformation, with-git-url + with-branch"): New test.
| Ludovic Courtès |
| 2019-03-17 | packages: Add 'package-input-rewriting/spec'....* guix/packages.scm (package-input-rewriting/spec): New procedure.
* tests/packages.scm ("package-input-rewriting/spec")
("package-input-rewriting/spec, partial match"): New tests.
* doc/guix.texi (Defining Packages): Document it.
| Ludovic Courtès |
| 2019-03-17 | guix build: Add '--with-git-url'....* guix/scripts/build.scm (%not-equal): New variable.
(evaluate-git-replacement-specs): Use it instead of local variable
'not-equal'.
(transform-package-source-git-url): New procedure.
(%transformations): Add 'with-git-url'.
(%transformation-options, show-transformation-options-help): Add
'--with-git-url'.

* guix/tests.scm (with-environment-variable): ... here.
* tests/build-utils.scm ("wrap-program, one input, multiple calls"):
Use it instead of 'setenv'.
| Ludovic Courtès |
| 2019-03-15 | pack: "-RR" produces PRoot-enabled relocatable binaries....* gnu/packages/aux-files/run-in-namespace.c (exec_with_proot): New
function.
(main): When 'clone' fails, call 'rm_rf'.
[PROOT_PROGRAM]: When 'clone' fails, call 'exec_with_proot'.
* guix/scripts/pack.scm (wrapped-package): Add #:proot?.
[proot]: New procedure.
[build]: Compile with -DPROOT_PROGRAM when PROOT? is true.
* guix/scripts/pack.scm (%options): Set the 'relocatable?' value to
'proot when "-R" is passed several times.
(guix-pack): Pass #:proot? to 'wrapped-package'.

user namespace support.
* doc/guix.texi (Invoking guix pack): Document -RR.

warning for "--inherit" and add -E/--preserve.

deprecated in commit 1de2fe95e017c42aacbaa34f5dab8d48249cc064 in 2015.
* tests/guix-environment.sh: Remove use of '-E'.
| Ludovic Courtès |
| 2019-02-16 | packages: Remove duplicates from package cache....Previously the same package could appear several times if several
variables were bound to it, as is notably the case for "python"
currently. This, in turn, would lead to obnoxious "ambiguous package
specification" messages.
* gnu/packages.scm (generate-package-cache)[expand-cache]: Change RESULT
to RESULT+SEEN and adjust accordingly.
Call 'first' on the result of 'fold-module-public-variables*'.

| 2019-02-07 | profiles: Raise an error for unmatched patterns....Previously, "guix package -r something-not-installed" would silently
complete. Now an error is raised.
* guix/profiles.scm (&unmatched-pattern-error): New condition type.
(manifest-matching-entries): Rewrite to raise an error when one of
PATTERNS is not matched.
* guix/ui.scm (call-with-error-handling): Handle 'unmatched-pattern-error?'.
* tests/guix-package.sh: Add test.
* tests/profiles.scm ("manifest-matching-entries"): Don't try to remove
unmatched pattern.
("manifest-matching-entries, no match"): New test.
("manifest-transaction-effects"): Remove 'remove' field.
| Ludovic Courtès |
| 2019-02-06 | daemon: Emit a 'build-succeeded' event in check mode....Until now, something like "guix build sed -v1 --check" would not get a
'build-succeeded' event, which in turn meant that the spinner would not
be erased upon build completion.
* nix/libstore/build.cc (DerivationGoal::registerOutputs): When
'buildMode' is bmCheck and 'settings.printBuildTrace' emit a
"@ build-succeeded" trace upon success.
* tests/store.scm ("build-succeeded trace in check mode"): New test.

(build, matching-build): New procedures.
(compute-status): Adjust to manipulate <build> records instead of
derivation file names in 'build-status-builds-completed' and
'build-status-building'.
(build-event-output-port)[process-line]: Use 'string-split' to preserve
spaces.
* tests/status.scm ("compute-status, builds + substitutes")
("compute-status, missing events"): Adjust to expect <build> records.
Produce complete "build-started" events.

c2dcff41c2e47f5f978f467864d5ed7829939884, whereby many tests in
'tests/packages.scm' would trigger a syntax error due to duplicate field
intializers in forms like:
(dummy-package "foo" (version "0"))
* guix/tests.scm (dummy-package, dummy-origin): Rewrite to inherit from
a base record. This restores the semantics from before
c2dcff41c2e47f5f978f467864d5ed7829939884.
