Created attachment 959536 [details] Patch for f21/f22 Scratch builds: http://koji.fedoraproject.org/koji/taskinfo?taskID=8198486 (x86/armv7) http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=2795416 (aarch64) http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=2192169 (ppc64/le) (In reply to Yaakov Selkowitz from comment #1) > http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=2192169 (ppc64/le) Correction: http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=2192168 Created attachment 959537 [details] Patch for f20 Scratch builds: http://koji.fedoraproject.org/koji/taskinfo?taskID=8198666 (x86/armv7) http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=2192303 (ppc/ppc64) I understand your concern and intention. Nevertheless, I cannot accept the patch, since: 1) Neither upstream execjs pulls in any JS framework and the choice is up to user. 2) I don't want to force any non-required dependencies. E.g. if we go with therubyracer, but somebody wants to use NodeJS instead, there would be no way how to get rid of therubyracer package from the system. This is unacceptable (especially considering how much dependencies might be pulled in due to this). The solution for F21 and older is to use comps and I believe that therubyracer is included in rubyonrails group. For F22, I would consider Recommends dependencies instead of Requires.

Both therubyracer and nodejs require v8, so the only "extra" dependency in such a scenario would be rubygem-ref: http://koji.fedoraproject.org/koji/rpminfo?rpmID=5484240 http://koji.fedoraproject.org/koji/rpminfo?rpmID=5768388 > The solution for F21 and older is to use comps and I believe that > therubyracer is included in rubyonrails group. That neither helps nor works for secondary arches. Keep in mind that, due to the runtime tests in %check, that execjs currently cannot even be rebuilt on a secondary arch, e.g.: http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=2796540 At the minimum, everything but the added Requires: is necessary to make this package both build and run (after installing jsc) on secondary arches.

If JSC works, it makes sense to enable it by applying your patch. It also makes sense to ask upstream to support JSC not only on Macs, since it seems to be issue for other platforms as well [1]. > Keep in mind that, due to the runtime tests in %check, that execjs currently > cannot even be rebuilt on a secondary arch, e.g.: > > http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=2796540 We should make it build, definitely. Unfortunately, trying JSC on x86_64, it just segfaults. Moreover, since the jsc executable is available just in -devel subpackage, I am not sure how well it is supported. Would you mind to pursue webkitgtk4 maintainer to split the JSC into more reasonable subpackage and make it work actually?

The patch would need a bit of work to upstream, but it would be easier if we could rely on just "jsc" from webkitgtk4 and not jsc-{1,3} from the now-deprecated webkitgtk{,3}. > Unfortunately, trying JSC on x86_64, it just segfaults. The examples shown at https://github.com/sstephenson/execjs WFM on both x86_64 and aarch64 (after patching runtimes.rb). What exactly did you do? > Moreover, since the jsc executable is available just in -devel subpackage, I > am not sure how well it is supported.

Yes, sure. I'm interested what upstream thinks about this, since there are more directions in which the patch could be modified. > > Unfortunately, trying JSC on x86_64, it just segfaults. > > The examples shown at https://github.com/sstephenson/execjs WFM on both > x86_64 and aarch64 (after patching runtimes.rb). What exactly did you do? This is my SRPM: https://vondruch.fedorapeople.org/rubygem-execjs-2.2.2-1.fc22.src.rpm And the testsuite fails entirely. In a background, the test suite creates file with content such as: $ cat /tmp/execjs20141222-11666-14a8cabjs (function(program, execJS) { execJS(program) })(function() { return eval("(function(){ \n1 })()"); }, function(program) { var output; try { result = program(); if (typeof result == 'undefined' && result !== null) { print('["ok"]'); } else { try { print(JSON.stringify(['ok', result])); } catch (err) { print('["err"]'); } } } catch (err) { print(JSON.stringify(['err', '' + err])); } }); and runs: $ jsc /tmp/execjs20141222-11666-14a8cabjs Segmentation fault (core dumped) > > Would you mind to pursue webkitgtk4 maintainer to split the JSC into more > > reasonable subpackage and make it work actually? > > Filed bug 1176677.

On F21 -- which is what I was testing in the first place -- it passes if you uncomment the LANG=en_US.utf8 line. Since upstream 2.5.0 (released earlier this month), ExecJS now supports Duktape as a backend. F21+ are all at 2.2.0, so I haven't tested ExecJS with it, but Duktape itself does seem to work properly on AArch64. Therefore, the combination of a rubygem-execjs version bump and the addition of rubygem-duktape (which will require figuring out how to handle the bundled duktape.c) would provide a lightweight and portable alternative for all arches. This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase Does the switch from therubyracer to node for the test suite [1] changes the situation? Is NodeJS supported on all architectures now? [1] http://pkgs.fedoraproject.org/cgit/rpms/rubygem-execjs.git/commit/?id=3c0f1ff0c98c30d501659beea540aa206f2c3d66 nodejs since 4.x (F24) is supported on both aarch64 and ppc64{,le}. I don't think there is any action needed at this point. NodeJs is used to execute the test suite and it is available on all supported platforms. |
