Junio C Hamano	5f73076c1a	"Assume unchanged" git This adds "assume unchanged" logic, started by this message in the list discussion recently: <Pine.LNX.4.64.0601311807470.7301@g5.osdl.org> This is a workaround for filesystems that do not have lstat() that is quick enough for the index mechanism to take advantage of. On the paths marked as "assumed to be unchanged", the user needs to explicitly use update-index to register the object name to be in the next commit. You can use two new options to update-index to set and reset the CE_VALID bit: git-update-index --assume-unchanged path... git-update-index --no-assume-unchanged path... These forms manipulate only the CE_VALID bit; it does not change the object name recorded in the index file. Nor they add a new entry to the index. When the configuration variable "core.ignorestat = true" is set, the index entries are marked with CE_VALID bit automatically after: - update-index to explicitly register the current object name to the index file. - when update-index --refresh finds the path to be up-to-date. - when tools like read-tree -u and apply --index update the working tree file and register the current object name to the index file. The flag is dropped upon read-tree that does not check out the index entry. This happens regardless of the core.ignorestat settings. Index entries marked with CE_VALID bit are assumed to be unchanged most of the time. However, there are cases that CE_VALID bit is ignored for the sake of safety and usability: - while "git-read-tree -m" or git-apply need to make sure that the paths involved in the merge do not have local modifications. This sacrifices performance for safety. - when git-checkout-index -f -q -u -a tries to see if it needs to checkout the paths. Otherwise you can never check anything out ;-). - when git-update-index --really-refresh (a new flag) tries to see if the index entry is up to date. You can start with everything marked as CE_VALID and run this once to drop CE_VALID bit for paths that are modified. Most notably, "update-index --refresh" honours CE_VALID and does not actively stat, so after you modified a file in the working tree, update-index --refresh would not notice until you tell the index about it with "git-update-index path" or "git-update-index --no-assume-unchanged path". This version is not expected to be perfect. I think diff between index and/or tree and working files may need some adjustment, and there probably needs other cases we should automatically unmark paths that are marked to be CE_VALID. But the basics seem to work, and ready to be tested by people who asked for this feature. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Alex Riesen	88fb958baa	use result of open(2) to check for presence Not that the stat against open race would matter much in this context, but that simplifies the code a bit. Also some diagnostics added (why the open failed) Signed-off-by: Alex Riesen <raa.lkml@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago

Junio C Hamano	53e7181cd9	config.c: remove unnecessary header in minimum configuration file. It is just silly to start the file called "config" with a comment that says "This is the config file." Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago

Junio C Hamano	4e72dcec89	Introduce i18n.commitencoding. This is to hold what the project-local rule as to the charset/encoding for the commit log message is. Lack of it defaults to utf-8. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	4f629539cd	init-db: check template and repository format. This makes init-db repository version aware. It checks if an existing config file says the repository being reinitialized is of a wrong version and aborts before doing further harm. When copying the templates, it makes sure the they are of the right repository format version. Otherwise the templates are ignored with an warning message. It copies the templates before creating the HEAD, and if the config file is copied from the template directory, reads it, primarily to pick up the value of core.symrefsonly. It changes the way the result of the filemode reliability test is written to the configuration file using git_config_set(). The test is done even if the config file was copied from the templates. And finally, our own repository format version is written to the config file. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	3a2f2bb354	config.c: avoid shadowing global. This is purely cosmetic, but avoid shadowing "FILE *config_file" global in git_config_set_multivar() function. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	9ce392f482	Move diff.renamelimit out of default configuration. Otherwise we would end up linking all the unneeded stuff into git-daemon only to link with git_default_config. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Johannes Schindelin	b17e659dd4	Allow hierarchical section names A .git/config like follows becomes valid with this patch: [remote.junio] url = git://git.kernel.org/pub/scm/git/git.git pull = master:junio todo:todo +pu:pu [remote.ibook] url = ibook:git/ pull = master:ibook push = master:quetzal (This patch only does the ini file thing, git-fetch and friends still ignore these values).

Johannes Schindelin	f98d863d21	git-config-set: support selecting values by non-matching regex Extend the regex syntax of value_regex so that prepending an exclamation mark means non-match: [core] quetzal = "Dodo" for Brainf*ck quetzal = "T.

Johannes Schindelin	4ddba79db7	git-config-set: add more options ... namely --replace-all, to replace any amount of matching lines, not just 0 or 1, --get, to get the value of one key, --get-all, the multivar version of --get, and --unset-all, which deletes all matching lines from .git/config Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Johannes Schindelin	10bea152a3	Add functions git_config_set() and git_config_set_multivar() The function git_config_set() does exactly what you think it does. Given a key (in the form "core.filemode") and a value, it sets the key to the value. Example: git_config_set("core.filemode", "true"); The function git_config_set_multivar() is meant for setting variables which can have several values for the same key. Example: [diff] twohead = resolve twohead = recarsive the typo in the second line can be replaced by git_config_set_multivar("diff.twohead", "recursive", "^recar"); The third argument of the function is a POSIX extended regex which has to match the value. If there is no key/value pair with a matching value, a new key/value pair is added. These commands are also capable of unsetting (deleting) entries: git_config_set_multivar("diff.twohead", NULL, "sol"); will delete the entry twohead = resolve Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago

Junio C Hamano	3299c6f6a8	diff: make default rename detection limit configurable. A while ago, a rename-detection limit logic was implemented as a response to this thread: http://marc.theaimsgroup.com/?l=git&m=112413080630175 where gitweb was found to be using a lot of time and memory to detect renames on huge commits. git-diff family takes -l<num> flag, and if the number of paths that are rename destination candidates (i.e. new paths with -M, or modified paths with -C) are larger than that number, skips rename/copy detection even when -M or -C is specified on the command line. This commit makes the rename detection limit easier to use. You can have: [diff] renamelimit = 30 in your .git/config file to specify the default rename detection limit. You can override this from the command line; giving 0 means 'unlimited': git diff -M -l0 We might want to change the default behaviour, when you do not have the configuration, to limit it to say 20 paths or so. This would also help the diffstat generation after a big 'git pull'. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Johannes Schindelin	f8348be3be	Add config variable core.symrefsonly This allows you to force git to avoid symlinks for refs. Just add something like [core] symrefsonly = true to .git/config.

Linus Torvalds	4546738b58	Unlocalized isspace and friends Do our own ctype.h, just to get the sane semantics: we want locale-independence, _and_ we want the right signed behaviour. Plus we only use a very small subset of ctype.h anyway (isspace, isalpha, isdigit and isalnum). Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Linus Torvalds	128af9d1ef	Make git config variable names case-insensitive They always were meant to be case-insensitive, but I had missed one "tolower()", making that not true. The actual _values_ aren't case-insensitive, of course, although some uses of them may be (ie boolean parsing uses "strcasecmp()" to match against the strings "true" and "false").

Linus Torvalds	e1b10391ea	Use git config file for committer name and email info This starts using the "user.name" and "user.email" config variables if they exist as the default name and email when committing. This means that you don't have to use the GIT_COMMITTER_EMAIL environment variable to override your email - you can just edit the config file instead. The patch looks bigger than it is because it makes the default name and email information non-static and renames it appropriately. And it moves the common git environment variables into a new library file, so that you can link against libgit.a and get the git environment without having to link in zlib and libcrypt. In short, most of it is renaming and moving, the real change core is just a few new lines in "git_default_config()" that copies the user config values to the new base. It also changes "git-var -l" to list the config variables. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Linus Torvalds	5cbb401dba	Improve config file escape sanity checking I had meant to disallow unknown escape characters in the config file parser, but instead an unknown escaped character would silently pass through as itself. That's correct for some cases (notably '\' itself), but wasn't correct in general. This fixes it, and makes the parser write a nice error message if the config file contains bogus escaped characters.

Linus Torvalds	17712991a5	Add ".git/config" file parser This is a first cut at a very simple parser for a git config file. The format of the file is a simple ini-file like thing, with simple variable/value pairs. You can (and should) make the variables have a simple single-level scope, ie a valid file looks something like this: # # This is the config file, and # a '#' or ';' character indicates # a comment # ; core variables [core] ; Don't trust file modes filemode = false ; Our diff algorithm [diff] external = "/usr/local/bin/gnu-diff -u" renames = true which parses into three variables: "core.filemode" is associated with the string "false", and "diff.external" gets the appropriate quoted value. Right now we only react to one variable: "core.filemode" is a boolean that decides if we should care about the 0100 (user-execute) bit of the stat information. Even that is just a parsing demonstration - this doesn't actually implement that st_mode compare logic itself. Different programs can react to different config options, although they should always fall back to calling "git_default_config()" on any config option name that they don't recognize.
