2006-02-27apply --whitespace: configuration option.Libravatar Junio C Hamano1-0/+2
The new configuration option apply.whitespace can take one of "warn", "error", "error-all", or "strip". When git-apply is run to apply the patch to the index, they are used as the default value if there is no command line --whitespace option. Andrew can now tell people who feed him git trees to update to this version and say: git repo-config apply.whitespace error Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-02-18Delay "empty ident" errors until they really matter.Libravatar Junio C Hamano1-2/+2
Previous one warned people upfront to encourage fixing their environment early, but some people just use repositories and git tools read-only without making any changes, and in such a case there is not much point insisting on them having a usable ident. This round attempts to move the error until either "git-var" asks for the ident explicitly or "commit-tree" wants to use it. Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-02-10Make "git clone" less of a deathly quiet experienceLibravatar Linus Torvalds1-1/+1
It used to be that "git-unpack-objects" would give nice percentages, but now that we don't unpack the initial clone pack any more, it doesn't. And I'd love to do that nice percentage view in the pack objects downloader too, but the thing doesn't even read the pack header, much less know how much it's going to get, so I was lazy and didn't. Instead, it at least prints out how much data it's gotten, and what the packing speed is. Which makes the user realize that it's actually doing something useful instead of sitting there silently (and if the recipient knows how large the final result is, he can at least make a guess about when it migt be done). So with this patch, I get something like this on my DSL line: [torvalds@g5 ~]$ time git clone master.kernel.org:/pub/scm/linux/kernel/git/torvalds/linux-2.6 clone-test Packing 188543 objects 48.398MB (154 kB/s) where even the speed approximation seems to be roughtly correct (even though my algorithm is a truly stupid one, and only really gives "speed in the last half second or so"). Anyway, _something_ like this is definitely needed. It could certainly be better (if it showed the same kind of thing that git-unpack-objects did, that would be much nicer, but would require parsing the object stream as it comes in). But this is big step forward, I think. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-08"Assume unchanged" gitLibravatar Junio C Hamano1-2/+4
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>

2006-01-21Undef DT_* before redefining them.Libravatar Junio C Hamano1-0/+4
When overriding DT_* macro detection with NO_D_TYPE_IN_DIRENT (recent Cygwin build problem, which hopefully is already fixed in their CVS snapshot version), we define DTYPE() macro to return just "we do not know", but still needed to use DT_* macro to avoid ifdef in the code we use them. If the platform defines DT_* macro but with unusable d_type, this would have resulted in us redefining these preprocessor symbols. Admittedly, that would be just a couple of compilation warnings, and on Cygwin at least this particular problem is transitory (the problem is already fixed in their CVS snapshot version), so this is a low priority fix.

2006-01-07[PATCH] Compilation: zero-length array declaration.Libravatar Junio C Hamano1-4/+5
ISO C99 (and GCC 3.x or later) lets you write a flexible array at the end of a structure, like this: struct frotz { int xyzzy; char nitfol[]; /* more */ }; GCC 2.95 and 2.96 let you to do this with "char nitfol[0]"; unfortunately this is not allowed by ISO C90. This declares such construct like this: struct frotz { int xyzzy; char nitfol[FLEX_ARRAY]; /* more */ }; and git-compat-util.h defines FLEX_ARRAY to 0 for gcc 2.95 and empty for others. If you are using a C90 C compiler, you should be able to override this with CFLAGS=-DFLEX_ARRAY=1 from the command line of "make". Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-12-24Introduce core.sharedrepositoryLibravatar Johannes Schindelin1-0/+2
If the config variable 'core.sharedrepository' is set, the directories $GIT_DIR/objects/ $GIT_DIR/objects/?? $GIT_DIR/objects/pack $GIT_DIR/refs $GIT_DIR/refs/heads $GIT_DIR/refs/heads/tags are set group writable (and g+s, since the git group may be not the primary group of all users). Since all files are written as lock files first, and then moved to their destination, they do not have to be group writable. Indeed, if this leads to problems you found a bug. Note that -- as in my first attempt -- the config variable is set in the function which checks the repository format. If this were done in git_default_config instead, a lot of programs would need to be modified to call git_config(git_default_config) first.

2005-12-17fetch-pack: -k option to keep downloaded pack.Libravatar Junio C Hamano1-0/+5
Split out the functions that deal with the socketpair after finishing git protocol handshake to receive the packed data into a separate file, and use it in fetch-pack to keep/explode the received pack data. We earlier had something like that on clone-pack side once, but the list discussion resulted in the decision that it makes sense to always keep the pack for clone-pack, so unpacking option is not enabled on the clone-pack side, but we later still could do so easily if we wanted to with this change.

2005-11-27init-db: check template and repository format.Libravatar Junio C Hamano1-0/+1
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>

2005-11-19Add functions git_config_set() and git_config_set_multivar()Libravatar Johannes Schindelin1-0/+2
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>
2005-11-16git's rev-parse.c function show_datestring presumes gnu dateLibravatar Linus Torvalds1-0/+1
Ok. This is the insane patch to do this. It really isn't very careful, and the reason I call it "approxidate()" will become obvious when you look at the code. It is very liberal in what it accepts, to the point where sometimes the results may not make a whole lot of sense. It accepts "last week" as a date string, by virtue of "last" parsing as the number 1, and it totally ignoring superfluous fluff like "ago", so "last week" ends up being exactly the same thing as "1 week ago". Fine so far. It has strange side effects: "last december" will actually parse as "Dec 1", which actually _does_ turn out right, because it will then notice that it's not December yet, so it will decide that you must be talking about a date last year. So it actually gets it right, but it's kind of for the "wrong" reasons. It also accepts the numbers 1..10 in string format ("one" .. "ten"), so you can do "ten weeks ago" or "ten hours ago" and it will do the right thing. But it will do some really strange thigns too: the string "this will last forever", will not recognize anyting but "last", which is recognized as "1", which since it doesn't understand anything else it will think is the day of the month. So if you do gitk --since="this will last forever" the date will actually parse as the first day of the current month. And it will parse the string "now" as "now", but only because it doesn't understand it at all, and it makes everything relative to "now". Similarly, it doesn't actually parse the "ago" or "from now", so "2 weeks ago" is exactly the same as "2 weeks from now". It's the current date minus 14 days. But hey, it's probably better (and certainly faster) than depending on GNU date. So now you can portably do things like gitk --since="two weeks and three days ago" git log --since="July 5" git-whatchanged --since="10 hours ago" git log --since="last october" and it will actually do exactly what you thought it would do (I think). It will count 17 days backwards, and it will do so even if you don't have GNU date installed. (I don't do "last monday" or similar yet, but I can extend it to that too if people want). It was kind of fun trying to write code that uses such totally relaxed "understanding" of dates yet tries to get it right for the trivial cases. The result should be mixed with a few strange preprocessor tricks, and be submitted for the IOCCC ;) Feel free to try it out, and see how many strange dates it gets right. Or wrong. And if you find some interesting (and valid - not "interesting" as in "strange", but "interesting" as in "I'd be interested in actually doing this) thing it gets wrong - usually by not understanding it and silently just doing some strange things - please holler. Now, as usual this certainly hasn't been getting a lot of testing. But my code always works, no? Linus Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-11-15diff: make default rename detection limit configurable.Libravatar Junio C Hamano1-0/+1
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>

2005-10-26pack-objects: Allow use of pre-generated pack.Libravatar Junio C Hamano1-0/+1
git-pack-objects can reuse pack files stored in $GIT_DIR/pack-cache directory, when a necessary pack is found. This is hopefully useful when upload-pack (called from git-daemon) is expected to receive requests for the same set of objects many times (e.g full cloning request of any project, or updates from the set of heads previous day to the latest for a slow moving project). Currently git-pack-objects does *not* keep pack files it creates for reusing. It might be useful to add --update-cache option to it, which would allow it store pack files it created in the pack-cache directory, and prune rarely used ones from it.

2005-10-11Use git config file for committer name and email infoLibravatar Linus Torvalds1-0/+4
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.

2005-10-10Add ".git/config" file parserLibravatar Linus Torvalds1-0/+8
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.

This is a long overdue clean-up to the code for parsing and passing diff options. It also tightens some constness issues. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-20[PATCH] Return proper error valud from "parse_date()"Libravatar Linus Torvalds1-1/+1
Right now we don't return any error value at all from parse_date(), and if we can't parse it, we just silently leave the result buffer unchanged. That's fine for the current user, which will always default to the current date, but it's a crappy interface, and we might well be better off with an error message rather than just the default date. So let's change the thing to return a negative value if an error occurs, and the length of the result otherwise (snprintf behaviour: if the buffer is too small, it returns how big it _would_ have been). [ I started looking at this in case we could support date-based revision names. Looks ugly. Would have to parse relative dates.. ] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-20Show modified files in git-ls-filesLibravatar Junio C Hamano1-0/+1
Add -m/--modified to show files that have been modified wrt. the index. [jc: The original came from Brian Gerst on Sep 1st but it only checked if the paths were cache dirty without actually checking the files were modified. I also added the usage string and a new test.] Signed-off-by: Junio C Hamano <junkio@cox.net>
