[asterisk-bugs] [JIRA] (ASTERISK-25434) Compiler flags not reported in 'core show settings' despite usage during compilation

[Corey Farrell (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-25434?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Corey Farrell updated ASTERISK-25434:
-------------------------------------

    Attachment: cli-display-build-opts.patch

The attached patch creates a new function to allow CLI to display build options, including those which have no effect on ABI.  Worth noting this does duplicate a portion of {{build_tools/make_buildopts_h}}, but I'm not sure of a better way to deal with this without reverting the original commit.

>      Security Level: None
>          Components: Core/BuildSystem
>    Affects Versions: SVN, 13.4.0, 13.5.0
>         Environment: Ubuntu 12.04 , Linux newtonr-laptop 3.13.0-55-generic #94~precise1-Ubuntu SMP Thu Jun 18 09:53:13 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

> Edit: Issue may be that the string used by "core show settings" is not built correctly.. the actual options appear to get defined correctly.
> Description:
> Before building Asterisk, enable DONT_OPTIMIZE or BETTER_BACKTRACES in menuselect. After building and installing check "core show settings" and see that those options are not reported.
> I believe the flags are not actually set as I noticed the problem when I was reproducing a crash and saw optimizations in pjsip code despite having selected DONT_OPTIMIZE in menuselect.
> Other options such as DEBUG_THREADS or DEBUG_FD_LEAKS seem to work fine.
> Notes:
> I *cannot* reproduce in 13.3.2, but I *can* reproduce in 13.4.0, 13.5.0 and a git pull of 13 branch from today.
> I had [~kharwell] reproduce as well with a git pull from a few hours ago.
> That all being said, I could swear these options worked fine (disabling and enabling between builds) in 13.5.0 for the past weeks... Very confusing.
> I'm interested to see if others can reproduce.
> EDIT:
> Issue caused by commit:

>     Build System: Prevent unneeded changes to asterisk/buildopts.h.
>     
>     * Add AST_DEVMODE to BUILDOPTS
>     * Remove CFLAGS that do not effect ABI from BUILDOPTS.
>     * Use BUILDOPTS to generate AST_BUILDOPT_SUM.
>     * Remove loop that defined AST_MODULE_*
>     
>     These changes ensure that only ABI effecting options are considered for
>     AST_BUILDOPT_SUM.  This also reduces unneeded full system rebuilds caused
>     by enabling or disabling one module that another is dependent on.
