| * | | pkt-line: share buffer/descriptor reading implementationJeff King2013-02-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The packet_read function reads from a descriptor. The packet_get_line function is similar, but reads from an in-memory buffer, and uses a completely separate implementation. This patch teaches the generic packet_read function to accept either source, and we can do away with packet_get_line's implementation. There are two other differences to account for between the old and new functions. The first is that we used to read into a strbuf, but now read into a fixed size buffer. The only two callers are fine with that, and in fact it simplifies their code, since they can use the same static-buffer interface as the rest of the packet_read_line callers (and we provide a similar convenience wrapper for reading from a buffer rather than a descriptor). This is technically an externally-visible behavior change in that we used to accept arbitrary sized packets up to 65532 bytes, and now cap out at LARGE_PACKET_MAX, 65520. In practice this doesn't matter, as we use it only for parsing smart-http headers (of which there is exactly one defined, and it is small and fixed-size). And any extension headers would be breaking the protocol to go over LARGE_PACKET_MAX anyway. The other difference is that packet_get_line would return on error rather than dying. However, both callers of packet_get_line are actually improved by dying. The first caller does its own error checking, but we can drop that; as a result, we'll actually get more specific reporting about protocol breakage when packet_read dies internally. The only downside is that packet_read will not print the smart-http URL that failed, but that's not a big deal; anybody not debugging can already see the remote's URL already, and anybody debugging would want to run with GIT_CURL_VERBOSE anyway to see way more information. The second caller, which is just trying to skip past any extra smart-http headers (of which there are none defined, but which we allow to keep room for future expansion), did not error check at all. As a result, it would treat an error just like a flush packet. The resulting mess would generally cause an error later in get_remote_heads, but now we get error reporting much closer to the source of the problem.

| * | | pkt-line: provide a LARGE_PACKET_MAX static bufferJeff King2013-02-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the callers of packet_read_line just read into a static 1000-byte buffer (callers which handle arbitrary binary data already use LARGE_PACKET_MAX). This works fine in practice, because: 1. The only variable-sized data in these lines is a ref name, and refs tend to be a lot shorter than 1000 characters. 2. When sending ref lines, git-core always limits itself to 1000 byte packets. However, the only limit given in the protocol specification in Documentation/technical/protocol-common.txt is LARGE_PACKET_MAX; the 1000 byte limit is mentioned only in pack-protocol.txt, and then only describing what we write, not as a specific limit for readers. This patch lets us bump the 1000-byte limit to LARGE_PACKET_MAX. Even though git-core will never write a packet where this makes a difference, there are two good reasons to do this: 1. Other git implementations may have followed protocol-common.txt and used a larger maximum size. We don't bump into it in practice because it would involve very long ref names. 2. We may want to increase the 1000-byte limit one day. Since packets are transferred before any capabilities, it's difficult to do this in a backwards-compatible way. But if we bump the size of buffer the readers can handle, eventually older versions of git will be obsolete enough that we can justify bumping the writers, as well. We don't have plans to do this anytime soon, but there is no reason not to start the clock ticking now. Just bumping all of the reading bufs to LARGE_PACKET_MAX would waste memory. Instead, since most readers just read into a temporary buffer anyway, let's provide a single static buffer that all callers can use. We can further wrap this detail away by having the packet_read_line wrapper just use the buffer transparently and return a pointer to the static storage. That covers most of the cases, and the remaining ones already read into their own LARGE_PACKET_MAX buffers. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * | | pkt-line: teach packet_read_line to chomp newlinesJeff King2013-02-201-1/+1
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The packets sent during ref negotiation are all terminated by newline; even though the code to chomp these newlines is short, we end up doing it in a lot of places. This patch teaches packet_read_line to auto-chomp the trailing newline; this lets us get rid of a lot of inline chomping code. As a result, some call-sites which are not reading line-oriented data (e.g., when reading chunks of packfiles alongside sideband) transition away from packet_read_line to the generic packet_read interface. This patch converts all of the existing callsites. Since the function signature of packet_read_line does not change (but its behavior does), there is a possibility of new callsites being introduced in later commits, silently introducing an incompatibility. However, since a later patch in this series will change the signature, such a commit would have to be merged directly into this commit, not to the tip of the series; we can therefore ignore the issue. This is an internal cleanup and should produce no change of behavior in the normal case. However, there is one corner case to note. Callers of packet_read_line have never been able to tell the difference between a flush packet ("0000") and an empty packet ("0004"), as both cause packet_read_line to return a length of 0. Readers treat them identically, even though Documentation/technical/protocol-common.txt says we must not; it also says that implementations should not send an empty pkt-line. By stripping out the newline before the result gets to the caller, we will now treat the newline-only packet ("0005\n") the same as an empty packet, which in turn gets treated like a flush packet. In practice this doesn't matter, as neither empty nor newline-only packets are part of git's protocols (at least not for the line-oriented bits, and readers who are not expecting line-oriented packets will be calling packet_read directly, anyway). But even if we do decide to care about the distinction later, it is orthogonal to this patch. The right place to tighten would be to stop treating empty packets as flush packets, and this change does not make doing so any harder.

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.

* i18n: add infrastructure for translating Git with gettextab/enable-i18nÆvar Arnfjörð Bjarmason2011-12-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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".

* | mingw: implement syslogMike Pape2010-11-041-2/+0
|/ | | | | | | | | | | | | | | Syslog does not usually exist on Windows, so implement our own using Window's ReportEvent mechanism. Strings containing "%1" gets expanded into them selves by ReportEvent, resulting in an unreadable string. "%2" and above is not a problem. Unfortunately, on Windows an IPv6 address can contain "%1", so expand "%1" to "% 1" before reporting. "%%1" is also a problem for ReportEvent, but that string cannot occur in an IPv6 address.

Teach it to accept more than one --listen options. Remove the hostname information form the die, if no socket could be created. It would only trigger when no interface out of either all interface or the ones specified on the command line with --listen options, can be listened to and so the user does know which "host" was asked.

* Rewrite dynamic structure initializations to runtime assignmentGary V. Vaughan2010-05-311-10/+11
| | | | | | | | | | | | | | | | Unfortunately, there are still plenty of production systems with vendor compilers that choke unless all compound declarations can be determined statically at compile time, for example hpux10.20 (I can provide a comprehensive list of our supported platforms that exhibit this problem if necessary). This patch simply breaks apart any compound declarations with dynamic initialisation expressions, and moves the initialisation until after the last declaration in the same block, in all the places necessary to have the offending compilers accept the code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When NO_SOCKADDR_STORAGE is set for a platform, either sockaddr_in or sockaddr_in6 is used intead. Neither of which has an ss_family member. They have an sin_family and sin6_family member respectively. Since the addrcmp() function accesses the ss_family member of a sockaddr_storage struct, compilation fails on platforms which define NO_SOCKADDR_STORAGE. Since any sockaddr_* structure can be cast to a struct sockaddr and have its sa_family member read, do so here to workaround this issue. Thanks to Martin Storsjö for pointing out the fix, and Gary Vaughan for drawing attention to the issue.

This is slightly unreadable, and many users would expect "%%" to produce a single "%", as that is what printf format specifiers do. This patch converts "%%" to "%" for all users of strbuf_expand(): (1) git-daemon interpolated paths (2) pretty-print user formats (3) merge driver command lines Case (1) was already doing the conversion itself outside of strbuf_expand(). Case (2) is the intended beneficiary of this patch. Case (3) users probably won't notice, but as this is user-facing behavior, consistently providing the quoting mechanism makes sense.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kill_some_child() compares the entire sockaddr_storage structure (with the pad-bits zeroed out) when trying to find out if connections originate from the same host. However, sockaddr_storage contains the port-number for the connection (which varies between connections), so the comparison always fails. Change the code so we only consider the host-address, by introducing the addrcmp()-function that inspects the address family and compare as appropriate.

* | http-backend: Protect GIT_PROJECT_ROOT from /../ requestsShawn O. Pearce2009-11-091-48/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
