php8: fix and enhance configuration and dependencies #28234

📦 Package Details

Maintainer: @mhei

Description:

This commit cleans up and enhances the changes from 6d6233b, f9591b8, e6c59b5, and properly implements the attempt from 996046e.

By reasoning carefully about the impact of combinations of configuration options, and thoroughly setting config options and checking actual dynamic dependencies using readelf --dynamic, the configuration and dependency handling of these options has been improved.

In addition, cleanups and enhancements like reorganizing CONFIG_DEPENDS, adding more Kconfig help text, and cleaning up some whitespace have been performed.

A missing conditional BUILD_DEPENDS on package icu when PHP8_GETTEXT is defined has been added.
The PHP8_GETTEXT, PHP8_INTL, PHP8_FULLICUDATA, php8-mod-gettext, and php8-mod-intl interactions have been verified, fixed, and improved.
A circular dependency with php8-mod-xmlreader, PHP8_DOM, and php8-mod-dom when php8-mod-xmlreader is depended on by another package (e.g. zabbix-server-frontend) has been corrected
As these changes potentially impact binaries, there is a PKG_RELEASE bump.

* Add a needed BUILD_DEPENDENCY on icu package, when PHP8_GETTEXT is defined. * Make PHP8_INTL select/deselect properly depending on whether PHP8_GETTEXT is defined. Previously, deselecting PHP8_GETTEXT would select PHP8_INTL and make it impossible to deselect. * Only show option for choosing PHP8_FULLUCIDATA when all of PHP8_GETTEXT, PHP8_INTL, and the php8-mod-intl package are selected. * Make php8-mod-intl depend on php8-mod-gettext * For php8-mod-intl, depend on icu-full-data when PHP8_FULLUCIDATA is selected. * For php8-cgi, php-cli, etc, a libstdcpp dependency is only gained when PHP8_INTL is selected, therefore update those conditional depends. As some combinations of these changes can change the binaries output, PKG_RELEASE has been bumped. Signed-off-by: Daniel F. Dickinson <dfdpublic@wildtechgarden.ca>

Nice! At first glance, it looks good to me. I would like to have a deeper look tomorrow evening.

lang/php8/Makefile

xmlreader was selecting package php8-mod-dom as well as depending on PHP8_DOM, while php8-mod-dom also depended on PHP8_DOM (and therefore selected PHP8_DOM when php8-mod-dom was selected). This is a Kconfig recursive dependency, so break the recursion by noting that because php8-mod-xmlreader selects php8-mod-dom, PHP8_DOM is a transitive depends, so php8-mod-xmlreader should not depend on PHP8_DOM itself.

Noticed an issue with configuring with openssl when php8-mod-openssl is not selected, so fixed that.

Add more menuconfig help text descriptions, and convert some mixed tabs and spaces to spaces. Signed-off-by: Daniel F. Dickinson <dfdpublic@wildtechgarden.ca>

I've dropped the openssl changes - this looks like another can of worms.

nitpick: While at, I'd recommend to just order this alphabetically.

Here, I'd use "Without the dom module,..." or we could use the complete package names, e.g. "Without php8-mod-dom, this..."

+PKG_BUILD_DEPENDS:= PHP8_GETTEXT:icu


Do you mean PHP8_INTL here?

No, due to this configure line, which needs icu to compile, but icu does not become a php8 dependency for php8-mod-gettext because of it, nor is php8-mod-gettext required to be built (in the case php8-mod-gettext is not built, it affects php8-cli, php8-*cgi, and apache-mod-php8, so is still relevant).

ifeq ($(CONFIG_PHP8_GETTEXT),y) CONFIGURE_ARGS+= --with-gettext=shared,"$(STAGING_DIR)/usr/lib/libintl-full" else CONFIGURE_ARGS+= --without-gettext endif

prior to 6d6233b

this was

ifneq ($(SDK)$(CONFIG_PACKAGE_php8-mod-gettext),) CONFIGURE_ARGS+= --with-gettext=shared,"$(STAGING_DIR)/usr/lib/libintl-full" else CONFIGURE_ARGS+= --without-gettext endif

Here I'm still confused because:

before we had: PACKAGE_php8-mod-intl → --enable-intl=shared and +PACKAGE_php8-mod-intl:icu which added the runtime dep and thus kind of automatically added a build-dep only when the module was selected, parallel CONFIG_PACKAGE_php8-mod-gettext → --with-gettext=shared,"$(STAGING_DIR)/usr/lib/libintl-full" and the corresponding runtime dep to libintl-full, but without any reference to icu

now we have PHP8_INTL depends on PHP8_GETTEXT with: PHP8_INTL → --enable-intl=shared and PHP8_GETTEXT → --with-gettext=shared,"$(STAGING_DIR)/usr/lib/libintl-full"; independent of whether the modules are selected or not

In my tests, even when I don't declare the build dependency, then icu is built (I don't know why yet). But gettext seems to not have a runtime dep on icu (at least readelf does not show it), only intl does. So I assumed that it would make more sense to use PKG_BUILD_DEPENDS:= PHP8_INTL:icu here.

This is why I'm still confused - do you have other results/findings?

For me the GETTEXT "$(STAGING_DIR)/usr/lib/libintl-full fails with complaint about missing icu unless I use PKG_BUILD_DEPENDS:=PHP8_GETTEXT:icu.

gettext does not acquire a runtime dependency on icu despite that.

I have not tried to build mod-gettext without that config - perhaps it could be moved to PHP8_INTL? It was there from the original version, and I didn't try to change that part.

lang/php8/Makefile


 	config PHP8_FULLICUDATA
 		bool "Add dependency to full ICU Data"
-		depends on PHP8_INTL


PHP8_INTL already depends on PHP8_GETTEXT so this should not be required? And after looking at 72dd9ee again, since this flag is only affecting the php8-mod-intl, I think we should revert to use Package/php8-mod-intl/config stuff, so that this option is displayed near the package.

I moved it because Kconfig did not want to behave properly with it as Package/php8-mod-intl/config. I don't know if it's just the vagaries of Kconfig or if there is a bug to chase down, and in another couple of instances.

lang/php8/Makefile

 $(eval $(call BuildModule,gmp,GMP,+PACKAGE_php8-mod-gmp:libgmp))
 $(eval $(call BuildModule,iconv,iConv,$(ICONV_DEPENDS)))

@PHP_GETTEXT should not be required here since @PHP8_INTL already depends on it, right?

I'd prefer to leave the dependency to icu and icu-full-data as is: the dependency to icu is always required, and the dependency with PHP8_FULLICUDATA to icu-full-data is in my eyes just a "convenience" helper.

Kconfig issues again.

lang/php8/Makefile

 		bool "Enable Internationalization"

I have to do more tests, but at the moment, I don't see that PHP8_INTL must depend on PHP8_GETTEXT.
But on the other side, I think we should add to PHP8_LIBXML, PHP8_GETTEXT and PHP8_INTL a depends on depends on PACKAGE_php8 so that all options are hidden, if the "top-level" config option is not selected.

This was because Kconfig was behaving strangely without it.

Also adding a depends on PACKAGE_php8 gave me recursive dependency Kconfig problems.

I am not sure if I did try PHP8_INTL without PHP8_GETTEXT, that may be able to be disentangled.

Fixes: php8: global package dependency changes based on module selection Fixes: #28078 As described in #28078 and #28075, Some binaries gain a dependency on libstdcpp when mod-gettext is included in the build, however this was not explicitly declared, so packaging fails with (e.g.): Package php8-cgi is missing dependencies for the following libraries: libstdc++.so.6 In contrast to #28075, this commit takes the approach: * Make use of --with-gettext depend on a configure flag (enabled by default, since that matches current full build behaviour) * Make sub-packages which require --with-gettext depend on the configure flag This means that e.g. php-cgi would not have gettext support if the configure flag was disabled, and e.g. php-mod-gettext and php-mod-intl would not be selectable.

@mhei I have not given up on this - I've just not had a chance to try again. Kconfig can be a pain to work with.
