Prepare gitweb for having been split into modules that are to be installed alongside gitweb in 'lib/' subdirectory, by adding use lib __DIR__.'/lib'; to gitweb.perl (to main gitweb script), and preparing for putting modules (relative path) in $(GITWEB_MODULES) in gitweb/Makefile. This preparatory work allows to add new module to gitweb by simply adding GITWEB_MODULES += <module> to gitweb/Makefile (assuming that the module is in 'gitweb/lib/' directory). While at it pass GITWEBLIBDIR in addition to GITWEB_TEST_INSTALLED to test instaleed version of gitweb and installed version of modules (for tests which check individual (sub)modules). Using __DIR__ from Dir::Self module (not in core, that's why currently gitweb includes excerpt of code from Dir::Self defining __DIR__) was chosen over using FindBin-based solution (in core since perl 5.00307, while gitweb itself requires at least perl 5.8.0) because FindBin uses BEGIN block, which is a problem under mod_perl and other persistent Perl environments (thought there are workarounds). At Pavan Kumar Sankara suggestion gitweb/Makefile uses install [OPTION]... SOURCE... DIRECTORY format (2nd format) with single SOURCE rather than install [OPTION]... SOURCE DEST format (1st format) because of security reasons (race conditions). Modern GNU install has `-T' / `--no-target-directory' option, but we cannot rely that the $(INSTALL) we are using supports this option. The install-modules target in gitweb/Makefile uses shell 'for' loop, instead of make's $(foreach) function, to avoid possible problem with generating a command line that exceeded the maximum argument list length. Signed-off-by: Jakub Narebski <jnareb@xxxxxxxxx> --- This version is rebased on top of 'next', which means that it takes 'jn/gitweb-test' into account, in particular 958a846 (gitweb/Makefile: Add 'test' and 'test-installed' targets, 2010-09-26). That means adding GITWEBLIBDIR for future testing of individual modules (it was not present in v7.1). gitweb/Makefile | 17 +++++++++++++++-- gitweb/gitweb.perl | 8 ++++++++ 2 files changed, 23 insertions(+), 2 deletions(-) diff --git a/gitweb/Makefile b/gitweb/Makefile index 0a6ac00..f9e32eb 100644 --- a/gitweb/Makefile +++ b/gitweb/Makefile @@ -57,6 +57,7 @@ PERL_PATH ?= /usr/bin/perl bindir_SQ = $(subst ','\'',$(bindir))#' gitwebdir_SQ = $(subst ','\'',$(gitwebdir))#' gitwebstaticdir_SQ = $(subst ','\'',$(gitwebdir)/static)#' +gitweblibdir_SQ = $(subst ','\'',$(gitwebdir)/lib)#' SHELL_PATH_SQ = $(subst ','\'',$(SHELL_PATH))#' PERL_PATH_SQ = $(subst ','\'',$(PERL_PATH))#' DESTDIR_SQ = $(subst ','\'',$(DESTDIR))#' @@ -153,20 +154,32 @@ test: test-installed: GITWEB_TEST_INSTALLED='$(DESTDIR_SQ)$(gitwebdir_SQ)' \ + GITWEBLIBDIR='$(DESTDIR_SQ)$(gitweblibdir_SQ)' \ $(MAKE) -C ../t gitweb-test ### Installation rules -install: all +install: all install-modules $(INSTALL) -d -m 755 '$(DESTDIR_SQ)$(gitwebdir_SQ)' $(INSTALL) -m 755 $(GITWEB_PROGRAMS) '$(DESTDIR_SQ)$(gitwebdir_SQ)' $(INSTALL) -d -m 755 '$(DESTDIR_SQ)$(gitwebstaticdir_SQ)' $(INSTALL) -m 644 $(GITWEB_FILES) '$(DESTDIR_SQ)$(gitwebstaticdir_SQ)' +install-modules: + install_dirs="$(sort $(dir $(GITWEB_MODULES)))" && \ + for dir in $$install_dirs; do \ + test -d '$(DESTDIR_SQ)$(gitweblibdir_SQ)/$$dir' || \ + $(INSTALL) -d -m 755 '$(DESTDIR_SQ)$(gitweblibdir_SQ)/$$dir'; \ + done + gitweb_modules="$(GITWEB_MODULES)" && \ + for mod in $$gitweb_modules; do \ + $(INSTALL) -m 644 lib/$$mod '$(DESTDIR_SQ)$(gitweblibdir_SQ)/$$(dirname $$mod)'; \ + done + ### Cleaning rules clean: $(RM) gitweb.cgi static/gitweb.min.js static/gitweb.min.css GITWEB-BUILD-OPTIONS -.PHONY: all clean install test test-installed .FORCE-GIT-VERSION-FILE FORCE +.PHONY: all clean install install-modules test test-installed .FORCE-GIT-VERSION-FILE FORCE diff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl index 679f2da..cfa511c 100755 --- a/gitweb/gitweb.perl +++ b/gitweb/gitweb.perl @@ -10,6 +10,14 @@ use 5.008; use strict; use warnings; + +use File::Spec; +# __DIR__ is taken from Dir::Self __DIR__ fragment +sub __DIR__ () { + File::Spec->rel2abs(join '', (File::Spec->splitpath(__FILE__))[0, 1]); +} +use lib __DIR__ .
