2011-12-12credentials: add "store" helperLibravatar Jeff King1-0/+1
This is like "cache", except that we actually put the credentials on disk. This can be terribly insecure, of course, but we do what we can to protect them by filesystem permissions, and we warn the user in the documentation. This is not unlike using .netrc to store entries, but it's a little more user-friendly. Instead of putting credentials in place ahead of time, we transparently store them after prompting the user for them once.

2011-12-12add generic terminal prompt functionLibravatar Jeff King1-0/+9
When we need to prompt the user for input interactively, we want to access their terminal directly. We can't rely on stdio because it may be connected to pipes or files, rather than the terminal. Instead, we use "getpass()", because it abstracts the idea of prompting and reading from the terminal. However, it has some problems: 1. It never echoes the typed characters, which makes it OK for passwords but annoying for other input (like usernames). 2. Some implementations of getpass() have an extremely small input buffer (e.g., Solaris 8 is reported to support only 8 characters). 3. Some implementations of getpass() will fall back to reading from stdin (e.g., glibc). We explicitly don't want this, because our stdin may be connected to a pipe speaking a particular protocol, and reading will disrupt the protocol flow (e.g., the remote-curl helper). 4. Some implementations of getpass() turn off signals, so that hitting "^C" on the terminal does not break out of the password prompt. This can be a mild annoyance. Instead, let's provide an abstract "git_terminal_prompt" function that addresses these concerns. This patch includes an implementation based on /dev/tty, enabled by setting HAVE_DEV_TTY. The fallback is to use getpass() as before. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-12-11credentials: add "cache" helperLibravatar Jeff King1-0/+3
If you access repositories over smart-http using http authentication, then it can be annoying to have git ask you for your password repeatedly. We cache credentials in memory, of course, but git is composed of many small programs. Having to input your password for each one can be frustrating. This patch introduces a credential helper that will cache passwords in memory for a short period of time. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-12-11introduce credentials APILibravatar Jeff King1-0/+3
There are a few places in git that need to get a username and password credential from the user; the most notable one is HTTP authentication for smart-http pushing. Right now the only choices for providing credentials are to put them plaintext into your ~/.netrc, or to have git prompt you (either on the terminal or via an askpass program). The former is not very secure, and the latter is not very convenient. Unfortunately, there is no "always best" solution for password management. The details will depend on the tradeoff you want between security and convenience, as well as how git can integrate with other security systems (e.g., many operating systems provide a keychain or password wallet for single sign-on). This patch provides an abstract notion of credentials as a data item, and provides three basic operations: - fill (i.e., acquire from external storage or from the user) - approve (mark a credential as "working" for further storage) - reject (mark a credential as "not working", so it can be removed from storage) These operations can be backed by external helper processes that interact with system- or user-specific secure storage.

2011-12-05i18n: add infrastructure for translating Git with gettextLibravatar Ævar Arnfjörð Bjarmason1-4/+77
Change the skeleton implementation of i18n in Git to one that can show localized strings to users for our C, Shell and Perl programs using either GNU libintl or the Solaris gettext implementation. This new internationalization support is enabled by default. If gettext isn't available, or if Git is compiled with NO_GETTEXT=YesPlease, Git falls back on its current behavior of showing interface messages in English. When using the autoconf script we'll auto-detect if the gettext libraries are installed and act appropriately. This change is somewhat large because as well as adding a C, Shell and Perl i18n interface we're adding a lot of tests for them, and for those tests to work we need a skeleton PO file to actually test translations. A minimal Icelandic translation is included for this purpose. Icelandic includes multi-byte characters which makes it easy to test various edge cases, and it's a language I happen to understand. The rest of the commit message goes into detail about various sub-parts of this commit. = Installation Gettext .mo files will be installed and looked for in the standard $(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to override that, but that's only intended to be used to test Git itself. = Perl Perl code that's to be localized should use the new Git::I18n module. It imports a __ function into the caller's package by default. Instead of using the high level Locale::TextDomain interface I've opted to use the low-level (equivalent to the C interface) Locale::Messages module, which Locale::TextDomain itself uses. Locale::TextDomain does a lot of redundant work we don't need, and some of it would potentially introduce bugs. It tries to set the $TEXTDOMAIN based on package of the caller, and has its own hardcoded paths where it'll search for messages. I found it easier just to completely avoid it rather than try to circumvent its behavior. In any case, this is an issue wholly internal Git::I18N. Its guts can be changed later if that's deemed necessary. See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for a further elaboration on this topic. = Shell Shell code that's to be localized should use the git-sh-i18n library. It's basically just a wrapper for the system's gettext.sh. If gettext.sh isn't available we'll fall back on gettext(1) if it's available. The latter is available without the former on Solaris, which has its own non-GNU gettext implementation. We also need to emulate eval_gettext() there. If neither are present we'll use a dumb printf(1) fall-through wrapper. = About libcharset.h and langinfo.h We use libcharset to query the character set of the current locale if it's available. I.e. we'll use it instead of nl_langinfo if HAVE_LIBCHARSET_H is set. The GNU gettext manual recommends using langinfo.h's nl_langinfo(CODESET) to acquire the current character set, but on systems that have libcharset.h's locale_charset() using the latter is either saner, or the only option on those systems. GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either, but MinGW and some others need to use libcharset.h's locale_charset() instead. =Credits This patch is based on work by Jeff Epler <jepler@unpythonic.net> who did the initial Makefile / C work, and a lot of comments from the Git mailing list, including Jonathan Nieder, Jakub Narebski, Johannes Sixt, Erik Faye-Lund, Peter Krefting, Junio C Hamano, Thomas Rast and others.

2011-11-18Makefile: add option to disable automatic dependency generationLibravatar Jonathan Nieder1-7/+24
Now that the COMPUTE_HEADER_DEPENDENCIES feature is turned on automatically for compilers that support it (see v1.7.8-rc0~142^2~1, 2011-08-18), there is no easy way to force it off. For example, setting COMPUTE_HEADER_DEPENDENCIES to the empty string in config.mak just tells the makefile to treat it as undefined and run a test command to see if the -MMD option is supported. So allow setting COMPUTE_HEADER_DEPENDENCIES=no to explicitly force the feature off. The new semantics: - "yes" means to explicitly enable the feature - "no" means to disable it - "auto" means to autodetect The default is still "auto". Any value other than these three will cause the build to error out with a descriptive message so typos and stale settings in config.mak don't result in mysterious behavior. Makefile:1278: *** please set COMPUTE_HEADER_DEPENDENCIES to yes, no, or auto (not "1"). Stop. So now when someone using a compiler without -MMD support reports trouble building git, you can reproduce it by running "make COMPUTE_HEADER_DEPENDENCIES=no".

2011-11-04Split GPG interface into its own helper libraryLibravatar Junio C Hamano1-0/+2
This mostly moves existing code from builtin/tag.c (for signing) and builtin/verify-tag.c (for verifying) to a new gpg-interface.c file to provide a more generic library interface. - sign_buffer() takes a payload strbuf, a signature strbuf, and a signing key, runs "gpg" to produce a detached signature for the payload, and appends it to the signature strbuf. The contents of a signed tag that concatenates the payload and the detached signature can be produced by giving the same strbuf as payload and signature strbuf. - verify_signed_buffer() takes a payload and a detached signature as <ptr, len> pairs, and runs "gpg --verify" to see if the payload matches the signature. It can optionally capture the output from GPG to allow the callers to pretty-print it in a way more suitable for their contexts. "verify-tag" (aka "tag -v") used to save the whole tag contents as if it is a detached signature, and fed gpg the payload part of the tag. It relied on gpg to fail when the given tag is not signed but just is annotated. The updated run_gpg_verify() function detects the lack of detached signature in the input, and errors out without bothering "gpg". Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-10-09Makefile: fix permissions of mergetools/ checked out with permissive umaskLibravatar Jonathan Nieder1-2/+1
Ever since mergetool--lib was split into multiple files in v1.7.7-rc0~3^2~1 (2011-08-18), the Makefile takes care to reset umask and use tar --no-owner when installing merge tool definitions to $(gitexecdir)/mergetools/. Unfortunately it does not take into account the possibility that the permission bits of the files being copied might already be wrong. Rather than fixing the "tar" incantation and making it even more complicated, let's just use the "install" utility. This only means losing the ability to install executables and subdirectories of mergetools/, which wasn't used. Noticed by installing from a copy of git checked out with umask 002.

2011-10-03Makefile: do not set setgid bit on directories on GNU/kFreeBSDLibravatar Jonathan Nieder1-0/+1
The g+s bit on directories to make group ownership inherited is a SysVism --- BSD and most of its descendants do not need it since they do the sane thing by default without g+s. In fact, on some filesystems (but not all --- tmpfs works this way but UFS does not), the kernel of FreeBSD does not even allow non-root users to set setgid bit on directories and produces errors when one tries: $ git init --shared dir fatal: Could not make /tmp/dir/.git/refs writable by group Since the setgid bit would only mean "do what you were going to do already", it's better to avoid setting it. Accordingly, ever since v1.5.5-rc0~59^2 (Do not use GUID on dir in git init --share=all on FreeBSD, 2008-03-05), git on true FreeBSD has done exactly that. Set DIR_HAS_BSD_GROUP_SEMANTICS in the makefile for GNU/kFreeBSD, too, so machines that use glibc with the kernel of FreeBSD get the same fix. This fixes t0001-init.sh and t1301-shared-repo.sh on GNU/kFreeBSD when running tests with --root pointing to a directory that uses tmpfs.

2011-09-14refactor argv_array into generic codeLibravatar Jeff King1-0/+2
The submodule code recently grew generic code to build a dynamic argv array. Many other parts of the code can reuse this, too, so let's make it generically available. There are two enhancements not found in the original code: 1. We now handle the NULL-termination invariant properly, even when no strings have been pushed (before, you could have an empty, NULL argv). This was not a problem for the submodule code, which always pushed at least one argument, but was not sufficiently safe for generic code. 2. There is a formatted variant of the "push" function. This is a convenience function which was not needed by the submodule code, but will make it easier to port other users to the new code.

The Makefile enables CHECK_HEADER_DEPENDENCIES when the compiler supports generating header dependencies.

2011-08-19mergetool--lib: Refactor tools into separate filesLibravatar David Aguilar1-0/+11
Individual merge tools are now defined in a mergetools/$tool file which is sourced at runtime. The individual files are installed into $(git --exec-path)/mergetools/. New tools can be added by creating a new file instead of editing the git-mergetool--lib.sh scriptlet. http://thread.gmane.org/gmane.comp.version-control.git/134906/focus=135006 Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
