2018-06-29Makefile: fix the "built from commit" codeLibravatar Johannes Schindelin1-2/+3
In ed32b788c06 (version --build-options: report commit, too, if possible, 2017-12-15), we introduced code to let `git version --build-options` report the current commit from which the binaries were built, if any. To prevent erroneous commits from being reported (e.g. when unpacking Git's source code from a .tar.gz file into a subdirectory of a different Git project, as e.g. git_osx_installer does), we painstakingly set GIT_CEILING_DIRECTORIES when trying to determine the current commit. Except that we got the quoting wrong, and that variable therefore does not have the desired effect. The issue is that the $(shell) is resolved before the output is stuffed into the command-line with -DGIT_BUILT_FROM_COMMIT, and therefore is *not* inside quotes. And thus backslashing the quotes is wrong, as the quote gets literally inserted into the CEILING_DIRECTORIES variable. Let's fix that quoting, and while at it, also suppress the unhelpful message fatal: not a git repository (or any of the parent directories): .git that gets printed to stderr if no current commit could be determined, and might scare the occasional developer who simply tries to build Git from scratch.

2018-06-18Merge branch 'es/make-no-iconv'Libravatar Junio C Hamano1-10/+12
"make NO_ICONV=NoThanks" did not override NEEDS_LIBICONV (i.e. linkage of -lintl, -liconv, etc. that are platform-specific tweaks), which has been corrected. * es/make-no-iconv: Makefile: make NO_ICONV really mean "no iconv"
2018-06-15Makefile: make NO_ICONV really mean "no iconv"Libravatar Eric Sunshine1-10/+12
The Makefile tweak NO_ICONV is meant to allow Git to be built without iconv in case iconv is not installed or is otherwise dysfunctional. However, NO_ICONV's disabling of iconv is incomplete and can incorrectly allow "-liconv" to slip into the linker flags when NEEDS_LIBICONV is defined, which breaks the build when iconv is not installed. On some platforms, iconv lives directly in libc, whereas, on others it resides in libiconv. For the latter case, NEEDS_LIBICONV instructs the Makefile to add "-liconv" to the linker flags. config.mak.uname automatically defines NEEDS_LIBICONV for platforms which require it. The adding of "-liconv" is done unconditionally, despite NO_ICONV. Work around this problem by making NO_ICONV take precedence over NEEDS_LIBICONV.

2018-05-29make show-index a builtinLibravatar Jeff King1-1/+1
The git-show-index command is built as its own separate program. There's really no good reason for this, and it means we waste extra space on disk (and CPU time running the linker). Let's fold it in to the main binary as a builtin. The history here is actually a bit amusing. The program itself is mostly self-contained, and doesn't even use our normal pack index code. In a5031214c4 (slim down "git show-index", 2010-01-21), we even stopped using xmalloc() so that it could avoid libgit.a entirely. But then 040a655116 (cleanup: use internal memory allocation wrapper functions everywhere, 2011-10-06) switched that back to xmalloc, which later become ALLOC_ARRAY(). Making it a builtin should give us the best of both worlds: no wasted space and no need to avoid the usual patterns.

2018-05-10generate-cmds.sh: export all commands to command-list.hLibravatar Nguyễn Thái Ngọc Duy1-4/+9
The current generate-cmds.sh generates just enough to print "git help" output. That is, it only extracts help text for common commands. The script is now updated to extract help text for all commands and keep command classification a new file, command-list.h. This will be useful later: - "git help -a" could print a short summary of all commands instead of just the common ones. - "git" could produce a list of commands of one or more category. One of its use is to reduce another command classification embedded in git-completion.bash. The new file can be generated but is not used anywhere yet. The plan is we migrate away from common-cmds.h. Then we can kill off common-cmds.h build rules and generation code (and also delete duplicate content in command-list.h which we keep for now to not mess generate-cmds.sh up too much). PS. The new fixed column requirement on command-list.txt is technically not needed. But it helps simplify the code a bit at this stage. We could lift this restriction later if we want to.

2018-04-24Avoid multiple PREFIX definitionsLibravatar Philip Oakley1-1/+1
The short and sweet PREFIX can be confused when used in many places. Rename both usages to better describe their purpose. EXEC_CMD_PREFIX is used in full to disambiguate it from the nearby GIT_EXEC_PATH. The PREFIX in sideband.c, while nominally independant of the exec_cmd PREFIX, does reside within libgit[1], so the definitions would clash when taken together with a PREFIX given on the command line for use by exec_cmd.c. Noticed when compiling Git for Windows using MSVC/Visual Studio [1] which reports the conflict beteeen the command line definition and the definition in sideband.c within the libgit project. [1] the libgit functions are brought into a single sub-project within the Visual Studio construction script provided in contrib, and hence uses a single command for both exec_cmd.c and sideband.c.

I've long wanted to use DEVELOPER=1 in my production builds, but on some old systems I still get warnings, and thus the build would fail.

This is used to enable RUNTIME_PREFIX support for non-Windows systems, notably Linux and Darwin.

2018-04-11Makefile: add Perl runtime prefix supportLibravatar Dan Jacques1-1/+64
Broaden the RUNTIME_PREFIX flag to configure Git's Perl scripts to locate the Git installation's Perl support libraries by resolving against the script's path, rather than hard-coding that path at build-time. Hard-coding at build time worked on previous RUNTIME_PREFIX configurations (i.e., Windows) because the Perl scripts were run within a virtual filesystem whose paths were consistent regardless of the location of the actual installation. This will no longer be the case for non-Windows RUNTIME_PREFIX users. When enabled, RUNTIME_PREFIX now requires Perl's system paths to be expressed relative to a common installation directory in the Makefile, and uses that relationship to locate support files based on the known starting point of the script being executed, much like RUNTIME_PREFIX does for the Git binary. This change enables Git's Perl scripts to work when their Git installation is relocated or moved to another system, even when they are not in a virtual filesystem environment.

If one part of the code does a permanent chdir(), then this invalidates any relative paths that may be held by other parts of the code. For example, setup_work_tree() moves us to the top of the working tree, which may invalidate a previously stored relative gitdir. We've hacked around this case by teaching setup_work_tree() to re-run set_git_dir() with an adjusted path, but this stomps all over the idea of module boundaries. setup_work_tree() shouldn't have to know all of the places that need to be fed an adjusted path. And indeed, there's at least one other place (the refs code) which needs adjusting. Let's provide an API to let code that stores relative paths "subscribe" to updates to the current working directory. This means that callers of chdir() don't need to know about all subscribers ahead of time; they can simply consult a dynamically built list. Note that our helper function to reparent relative paths uses the simple remove_leading_path(). We could in theory use the much smarter relative_path(), but that led to some problems as described in 41894ae3a3 (Use simpler relative_path when set_git_dir, 2013-10-14). Since we're aiming to replace the setup_work_tree() code here, let's follow its lead. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
