* daemon: --access-hook optionJunio C Hamano2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | The --access-hook option to "git daemon" specifies an external command to be run every time a client connects, with - service name (e.g. "upload-pack", etc.), - path to the repository, - hostname (%H), - canonical hostname (%CH), - ip address (%IP), - tcp port (%P) as its command line arguments. The external command can decide to decline the service by exiting with a non-zero status (or to allow it by exiting with a zero status). It can also look at the $REMOTE_ADDR and $REMOTE_PORT environment variables to learn about the requestor when making this decision. The external command can optionally write a single line to its standard output to be sent to the requestor as an error message when it declines the service. Acked-by: Shawn O.

| | | | | | | | | | | If a client tries to connect after git-daemon starts, but before it opens a listening socket, the connection will fail.

* i18n: add infrastructure for translating Git with gettextÆvar Arnfjörð Bjarmason2011-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the git-daemon is asked about an inaccessible repository, it simply hangs up the connection without saying anything further. This makes it hard to distinguish between a repository we cannot access (e.g., due to typo), and a service or network outage. Instead, let's print an "ERR" line, which git clients understand since v1.6.1 (2008-12-24). Because there is a risk of leaking information about non-exported repositories, by default all errors simply say "access denied or repository not exported". Sites which don't have hidden repositories, or don't care, can pass a flag to turn on more specific messages.

* daemon: support <directory> arguments againJonathan Nieder2011-01-04
| | | | | | | | | | | | | | | | | | | | | | Ever since v1.7.4-rc0~125^2~8 (daemon: use run-command api for async serving, 2010-11-04), git daemon spawns child processes instead of forking to serve requests. The child processes learn that they are being run for this purpose from the presence of the --serve command line flag. When running with <ok_path> arguments, the --serve flag is treated as one of the path arguments and the special child behavior does not kick in. So the child becomes an ordinary git daemon process, notices that all the addresses it needs are in use, and exits with the message "fatal: unable to allocate any listen sockets on port 9418". Fix it by putting --serve at the beginning of the command line, where the flag cannot be mistaken for a path argument.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Eons ago HPA taught git-daemon how to protect itself from /../ attacks, which Junio brought back into service in d79374c7b58d ("daemon.c and path.enter_repo(): revamp path validation"). I did not carry this into git-http-backend as originally we relied only upon PATH_TRANSLATED, and assumed the HTTP server had done its access control checks to validate the resolved path was within a directory permitting access from the remote client. This would usually be sufficient to protect a server from requests for its /etc/passwd file by http://host/smart/../etc/passwd sorts of URLs. However in 917adc036086 Mark Lodato added GIT_PROJECT_ROOT as an additional method of configuring the CGI. When this environment variable is used the web server does not generate the final access path and therefore may blindly pass through "/../etc/passwd" in PATH_INFO under the assumption that "/../" might have special meaning to the invoked CGI. Instead of permitting these sorts of malformed path requests, we now reject them back at the client, with an error message for the server log. This matches git-daemon behavior.

This patch arranges that the daemon does not merely exec the service program, but forks it and monitors stderr of the child; it writes the errors that it produces to the daemons log via logerror(). A consequence is that the daemon process remains in memory for the full duration of the service program, but this cannot be avoided.

* | Fix various sparse warnings in the git source codeLinus Torvalds2009-06-20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few remaining ones, but this fixes the trivial ones. It boils down to two main issues that sparse complains about: - warning: Using plain integer as NULL pointer Sparse doesn't like you using '0' instead of 'NULL'. For various good reasons, not the least of which is just the visual confusion. A NULL pointer is not an integer, and that whole "0 works as NULL" is a historical accident and not very pretty. A few of these remain: zlib is a total mess, and Z_NULL is just a 0. I didn't touch those. - warning: symbol 'xyz' was not declared. Should it be static? Sparse wants to see declarations for any functions you export. A lack of a declaration tends to mean that you should either add one, or you should mark the function 'static' to show that it's in file scope. A few of these remain: I only did the ones that should obviously just be made static. That 'wt_status_submodule_summary' one is debatable. It has a few related flags (like 'wt_status_use_color') which _are_ declared, and are used by builtin-commit.c. So maybe we'd like to export it at some point, but it's not declared now, and not used outside of that file, so 'static' it is in this patch.

* daemon: Strictly parse the "extra arg" part of the commandShawn O. Pearce2009-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 1.4.4.5 (49ba83fb67 "Add virtualization support to git-daemon") git daemon enters an infinite loop and never terminates if a client hides any extra arguments in the initial request line which is not exactly "\0host=blah\0". Since that change, a client must never insert additional extra arguments, or attempt to use any argument other than "host=", as any daemon will get stuck parsing the request line and will never complete the request. Since the client can't tell if the daemon is patched or not, it is not possible to know if additional extra args might actually be able to be safely requested. If we ever need to extend the git daemon protocol to support a new feature, we may have to do something like this to the exchange: # If both support git:// v2 # C: 000cgit://v2 S: 0010ok host user C: 0018host git.kernel.org C: 0027git-upload-pack /pub/linux-2.6.git S: ...git-upload-pack header... # If client supports git:// v2, server does not: # C: 000cgit://v2 S: <EOF> C: 003bgit-upload-pack /pub/linux-2.6.git\0host=git.kernel.org\0 S: ...git-upload-pack header... This requires the client to create two TCP connections to talk to an older git daemon, however all daemons since the introduction of daemon.c will safely reject the unknown "git://v2" command request, so the client can quite easily determine the server supports an older protocol.

* daemon.c: fix segfault on OS XBenjamin Kramer2009-04-29
| | | | | | | | | | | | | | | | | | On OS X (and maybe other unices), getaddrinfo(3) returns NULL in the ai_canonname field if it's called with an IP address for the hostname. We'll now use the IP address for the hostname if ai_canonname was NULL, this also matches the behaviour on Linux. steps to reproduce: $ git daemon --export-all $ git clone git://127.0.0.1/frotz => git daemon's fork (silently) segfaults. Remove the pointless loop while at it. There is only one iteration because of the break; on the last line and there are no continues.

* improve missing repository error messageJeff King2009-03-04
| | | | | | | | | | | | | | | | Certain remote commands, when asked to do something in a particular directory that was not actually a git repository, would say "unable to chdir or not a git archive". The "chdir" bit is an unnecessary detail, and the term "git archive" is much less common these days than "git repository".

* Add calls to git_extract_argv0_path() in programs that call git_config_*Steffen Prohaska2009-01-26
| | | | | | | | | | | | Programs that use git_config need to find the global configuration. When runtime prefix computation is enabled, this requires that git_extract_argv0_path() is called early in the program's main(). This commit adds the necessary calls.
