2009-11-09Retire fetch--tool helper to contrib/examplesJonathan Nieder1-1/+0
When git-fetch was builtin-ized, the previous script was moved to contrib/examples. Now, it is the sole remaining user for 'git fetch--tool'. The fetch--tool code is still worth keeping around so people can try out the old git-fetch.sh, for example when investigating regressions from the builtinifaction.

2009-11-04Git-aware CGI to provide dumb HTTP transportShawn O. Pearce1-0/+1
The git-http-backend CGI can be configured into any Apache server using ScriptAlias, such as with the following configuration: LoadModule cgi_module /usr/libexec/apache2/mod_cgi.so LoadModule alias_module /usr/libexec/apache2/mod_alias.so ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/ Repositories are accessed via the translated PATH_INFO. The CGI is backwards compatible with the dumb client, allowing all older HTTP clients to continue to download repositories which are managed by the CGI. Signed-off-by: Shawn O.

2009-10-27Do not try to remove directories when removing old linksSebastian Schuberth1-1/+1
When building Git with MSVC on Windows, directories named after the Git alias are created for the output files, e.g. there is a "git-merge-index" directory next to the "git-merge-index.exe" executable in the build root. Previously, "make all" just checked if "git-merge-index" and "git-merge-index.exe" are the same file, and if not, tried to remove "git-merge-index". This fails in the case of "git-merge-index" being a directory, which is why this is checked now.

2009-10-22Quote ' as \(aq in manpagesThomas Rast1-0/+4
The docbook/xmlto toolchain insists on quoting ' as \'. This does achieve the quoting goal, but modern 'man' implementations turn the apostrophe into a unicode "proper" apostrophe (given the right circumstances), breaking code examples in many of our manpages. Quote them as \(aq instead, which is an "apostrophe quote" as per the groff_char manpage. Unfortunately, as Anders Kaseorg kindly pointed out, this is not portable beyond groff, so we add an extra Makefile variable GNU_ROFF which you need to enable to get the new quoting.

2009-10-19Introduce commit notesJohannes Schindelin1-0/+2
Commit notes are blobs which are shown together with the commit message. These blobs are taken from the notes ref, which you can configure by the config variable core.notesRef, which in turn can be overridden by the environment variable GIT_NOTES_REF. The notes ref is a branch which contains "files" whose names are the names of the corresponding commits (i.e. the SHA-1). The rationale for putting this information into a ref is this: we want to be able to fetch and possibly union-merge the notes, maybe even look at the date when a note was introduced, and we want to store them efficiently together with the other objects. This patch has been improved by the following contributions: - Thomas Rast: fix core.notesRef documentation - Tor Arne Vestbø: fix printing of multi-line notes - Alex Riesen: Using char array instead of char pointer costs less BSS - Johan Herland: Plug leak when msg is good, but msglen or type causes return Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Tor Arne Vestbø <tavestbo@trolltech.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com> get_commit_notes(): Plug memory leak when 'if' triggers, but not because of read_sha1_file() failure

2009-10-08Makefile: add a note about the NO_MMAP setting on IRIX and IRIX64Brandon Casey1-0/+12
When git is compiled with the MIPSpro 7.4.4m compiler, and NO_PTHREADS is set, and NO_MMAP is _not_ set, then git segfaults when trying to access the first entry in a reflog. If NO_PTHREADS is not set (which implies that the pthread library is linked in), or NO_MMAP _is_ set, then the segfault is not encountered. The conservative choice has been made to set NO_MMAP in the Makefile to avoid this flaw. The GNU C compiler does not produce this behavior. The segfault happens in refs.c:read_ref_at(). The mmap succeeds, and the loop is executed properly until rec is rewound into the first line (reflog entry) of the file. The segfault is caught by test 28 of t1400-update-ref.sh which fails when 'git rev-parse --verify "master@{May 25 2005}"' is called. So, add a comment in the Makefile to describe why NO_MMAP is set and as a hint to those who may be interested in unsetting it.

Since commit dcda3614 removed the use of a variable length array from builtin-pack-objects.c, it is now safe to compile with the threaded delta search feature enabled.

2009-10-08Fix MSVC build on cygwinRamsay Jones1-1/+1
In the MSVC section of the Makefile, BASIC_CFLAGS is set to a value which contains the string "-DWIN32-D_CONSOLE". This results in a (single) malformed -Define being passed to the compiler. At least on my cygwin installation, the msvc compiler seems to ignore this parameter, without issuing an error or warning, and results in the WIN32 and _CONSOLE macros being undefined. This breaks the build. In order to fix the build, we simply insert a space between the two -Define parameters, "-DWIN32" and "-D_CONSOLE", as originally intended.

2009-09-10Makefile: Add NEEDS_CRYPTO_WITH_SSLBrian Gernhardt1-1/+7
The Makefile comment for NEEDS_SSL_WITH_CRYPTO says to define it "if you need -lcrypto with -lssl (Darwin)." However, what it actually does is add -lssl when you use -lcrypto and not the other way around. However, libcrypto contains a majority of the ERR_* functions from OpenSSL (at least on OS X) so we need it both ways. So, add NEEDS_CRYPTO_WITH_SSL which adds -lcrypto to the OpenSSL link flags and clarify the difference between it and NEEDS_SSL_WITH_CRYPTO.

2009-09-01gitweb: Incremental blame (using JavaScript)Jakub Narebski1-1/+5
Add 'blame_incremental' view, which uses "git blame --incremental" and JavaScript (Ajax), where 'blame' use "git blame --porcelain". * gitweb generates initial info by putting file contents (from "git cat-file") together with line numbers in blame table * then gitweb makes web browser JavaScript engine call startBlame() function from gitweb.js * startBlame() opens XMLHttpRequest connection to 'blame_data' view, which in turn calls "git blame --incremental" for a file, and streams output of git-blame to JavaScript (gitweb.js) * XMLHttpRequest event handler updates line info in blame view as soon as it gets data from 'blame_data' (from server), and it also updates progress info * when 'blame_data' ends, and gitweb.js finishes updating line info, it fixes colors to match (as far as possible) ordinary 'blame' view, and updates information about how long it took to generate page. Gitweb deals with streamed 'blame_data' server errors by displaying them in the progress info area (just in case). The 'blame_incremental' view tries to be equivalent to 'blame' action; there are however a few differences in output between 'blame' and 'blame_incremental' view: * 'blame_incremental' always used query form for this part of link(s) which is generated by JavaScript code. The difference is visible if we use path_info link (pass some or all arguments in path_info). Changing this would require implementing something akin to href() subroutine from gitweb.perl in JavaScript (in gitweb.js). * 'blame_incremental' always uses "rowspan" attribute, even if rowspan="1". This simplifies code, and is not visible to user. * The progress bar and progress info are still there even after JavaScript part of 'blame_incremental' finishes work. Note that currently no link generated by gitweb leads to this new view. This code is based on patch by Petr Baudis <pasky@suse.cz> patch, which in turn was tweaked up version of Fredrik Kuivinen <frekui@gmail.com>'s proof of concept patch. This patch adds GITWEB_JS compile configuration option, and modifies git-instaweb.sh to take gitweb.js into account. The code for git-instaweb.sh was taken from Pasky's patch.

It is true that NEEDS_RESOLV is needed on SunOS if NO_IPV6 is set since hstrerror() resides in libresolv, but performing this test at its current location is not very useful. It will only have any effect if the user modifies the make variables from the make command line, and will have no effect if a config.mak file is used. A better location for this conditional would have been further down in the Makefile after the config.mak and config.mak.autogen had been parsed. Rather than adding clutter to the Makefile for a conditional that will likely never be triggered, just remove it, and any user on SunOS that manually sets NO_IPV6 can also set NEEDS_RESOLV.

The first "grep -C1" test in t7002 does not pass on my SunOS-5.11-i86pc, and that is not because our way to spawn external grep is broken, but because the native grep does not understand -C<n>. It turns out that Peff was also using this option himself because our Makefile doesn't do that automatically. Brandon Casey uses SUNWspro compiler without having to set this, and it turns out that the compiler does not define preprocessor macro __unix__ which made him always use the built-in grep, never an external one.
