* Merge branch 'rs/run-command-env-array'Junio C Hamano2014-10-24
|\ | | | | | | | | | | | | | | | | Add managed "env" array to child_process to clarify the lifetime rules. * rs/run-command-env-array: use env_array member of struct child_process run-command: add env_array, an optional argv_array for env
| * use env_array member of struct child_processRené Scharfe2014-10-19
| | | | | | | | | | | | | | | | | | | | | | Convert users of struct child_process to using the managed env_array for specifying environment variables instead of supplying an array on the stack or bringing their own argv_array. This shortens and simplifies the code and ensures automatically that the allocated memory is freed after use.

* | refs.c: change resolve_ref_unsafe reading argument to be a flags fieldRonnie Sahlberg2014-10-15
|/ | | | | | | | | | | | | | | | | | resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref resolves successfully for writing but not for reading). Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited. Give the wrapper functions resolve_refdup and read_ref_full the same treatment for consistency.

* | use skip_prefix to avoid magic numbersJeff King2014-06-20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's a common idiom to match a prefix and then skip past it with a magic number, like: if (starts_with(foo, "bar")) foo += 3; This is easy to get wrong, since you have to count the prefix string yourself, and there's no compiler check if the string changes. We can use skip_prefix to avoid the magic numbers here. Note that some of these conversions could be much shorter. For example: if (starts_with(arg, "--foo=")) { bar = arg + 6; continue; } could become: if (skip_prefix(arg, "--foo=", &bar)) continue; However, I have left it as: if (skip_prefix(arg, "--foo=", &v)) { bar = v; continue; } to visually match nearby cases which need to actually process the string. Like: if (skip_prefix(arg, "--foo=", &v)) { bar = atoi(v); continue; } Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* http-backend: respect existing GIT_COMMITTER_* variablesJeff King2012-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | The http-backend program sets default GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL variables based on the REMOTE_USER and REMOTE_ADDR variables provided by the webserver. However, it unconditionally overwrites any existing GIT_COMMITTER variables, which may have been customized by site-specific code in the webserver (or in a script wrapping http-backend). Let's leave those variables intact if they already exist, assuming that any such configuration was intentional. There is a slight chance of a regression if somebody has set GIT_COMMITTER_* for the entire webserver, not intending it to leak through http-backend. We could protect against this by passing the information in alternate variables. However, it seems unlikely that anyone will care about that regression, and there is value in the simplicity of using the common variable names that are used elsewhere in git. While we're tweaking the environment-handling in http-backend, let's switch it to use argv_array to handle the list of variables. That makes the memory management much simpler.

* 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.

* zlib: zlib can only process 4GB at a timeJunio C Hamano2011-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The size of objects we read from the repository and data we try to put into the repository are represented in "unsigned long", so that on larger architectures we can handle objects that weigh more than 4GB. But the interface defined in zlib.h to communicate with inflate/deflate limits avail_in (how many bytes of input are we calling zlib with) and avail_out (how many bytes of output from zlib are we ready to accept) fields effectively to 4GB by defining their type to be uInt. In many places in our code, we allocate a large buffer (e.g. mmap'ing a large loose object file) and tell zlib its size by assigning the size to avail_in field of the stream, but that will truncate the high octets of the real size. The worst part of this story is that we often pass around z_stream (the state object used by zlib) to keep track of the number of used bytes in input/output buffer by inspecting these two fields, which practically limits our callchain to the same 4GB limit. Wrap z_stream in another structure git_zstream that can express avail_in and avail_out in unsigned long. For now, just die() when the caller gives a size that cannot be given to a single zlib call. In later patches in the series, we would make git_inflate() and git_deflate() internally loop to give callers an illusion that our "improved" version of zlib interface can operate on a buffer larger than 4GB in one go.

This goes on in an infinite loop until the stack overflows and the process is killed by SIGSEGV. Instead set a flag on the first die() invocation and if we came back to the handler, just die silently, as it only means we failed to report the failure---we cannot report anything anyway in such a case. This way failures to write the error messages to the stdout pipe do not result in an infinite loop.

We also shouldn't be passing a size_t parameter to printf when we've used PRIuMAX as the format specifier. Fix both issues by using uintmax_t for the hdr_int() routine, allowing strbuf's size_t to automatically upcast, and off_t to always fit. Also fixed the copy loop we use inside of send_local_file(), we never actually updated the size variable so we might as well not use it.

* http-backend: Protect GIT_PROJECT_ROOT from /../ requestsShawn O. Pearce2009-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | Requests for $GIT_URL/git-receive-pack and $GIT_URL/git-upload-pack are forwarded to the corresponding backend process by directly executing it and leaving stdin and stdout connected to the invoking web server. Prior to starting the backend process the HTTP response headers are sent, thereby freeing the backend from needing to know about the HTTP protocol. Requests that are encoded with Content-Encoding: gzip are automatically inflated before being streamed into the backend. This is primarily useful for the git-upload-pack backend, which receives highly repetitive text data from clients that easily compresses to 50% of its original size. Signed-off-by: Shawn O.
