| * Introduce is_bare_repository() and core.bare configuration variableJunio C Hamano2007-01-07
| | | | | | | | | | | | | | | | | | | | | | This removes the old is_bare_git_dir(const char *) to ask if a directory, if it is a GIT_DIR, is a bare repository, and replaces it with is_bare_repository(void *). The function looks at core.bare configuration variable if exists but uses the old heuristics: if it is ".git" or ends with "/.git", then it does not look like a bare repository, otherwise it does.

When we send a value to store_write_pair(), make sure that the value that gets read out matches the one passed in.

| * Teach Git how to parse standard power of 2 suffixes.Shawn O. Pearce2006-12-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes its necessary to supply a value as a power of two in a configuration parameter. In this case the user may want to use the standard suffixes such as K, M, or G to indicate that the numerical value should be multiplied by a constant base before being used. Shell scripts/etc. can also benefit from this automatic option parsing with `git repo-config --int`. [jc: with a couple of test and a slight input tightening] Signed-off-by: Shawn O.

* | Replace mmap with xmmap, better handling MAP_FAILED.Shawn O. Pearce2006-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases we did not even bother to check the return value of mmap() and just assume it worked. This is bad, because if we are out of virtual address space the kernel returned MAP_FAILED and we would attempt to dereference that address, segfaulting without any real error output to the user. We are replacing all calls to mmap() with xmmap() and moving all MAP_FAILED checking into that single location. If a mmap call fails we try to release enough least-recently-used pack windows to possibly succeed, then retry the mmap() attempt. If we cannot mmap even after releasing pack memory then we die() as none of our callers have any reasonable recovery strategy for a failed mmap. Signed-off-by: Shawn O.

* | Ensure core.packedGitWindowSize cannot be less than 2 pages.Shawn O. Pearce2006-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We cannot allow a window to be smaller than 2 system pages. This limitation is necessary to support the feature of use_pack() where we always supply at least 20 bytes after the offset to help the object header and delta base parsing routines. If packedGitWindowSize were allowed to be as small as 1 system page then we would be completely unable to access an object header which spanned over a page as we would never be able to arrange a mapping such that the header was contiguous in virtual memory.

* | Fully activate the sliding window pack access.Shawn O. Pearce2006-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This finally turns on the sliding window behavior for packfile data access by mapping limited size windows and chaining them under the packed_git->windows list. We consider a given byte offset to be within the window only if there would be at least 20 bytes (one hash worth of data) accessible after the requested offset. This range selection relates to the contract that use_pack() makes with its callers, allowing them to access one hash or one object header without needing to call use_pack() for every byte of data obtained. In the worst case scenario we will map the same page of data twice into memory: once at the end of one window and once again at the start of the next window. This duplicate page mapping will happen only when an object header or a delta base reference is spanned over the end of a window and is always limited to just one page of duplication, as no sane operating system will ever have a page size smaller than a hash. I am assuming that the possible wasted page of virtual address space is going to perform faster than the alternatives, which would be to copy the object header or ref delta into a temporary buffer prior to parsing, or to check the window range on every byte during header parsing. We may decide to revisit this decision in the future since this is just a gut instinct decision and has not actually been proven out by experimental testing. Signed-off-by: Shawn O.

* | Introduce new config option for mmap limit.Shawn O. Pearce2006-12-29
|/ | | | | | | | | | | | | | | | | Rather than hardcoding the maximum number of bytes which can be mmapped from pack files we should make this value configurable, allowing the end user to increase or decrease this limit on a per-repository basis depending on the size of the repository and the capabilities of their operating system. In general users should not need to manually tune such a low-level setting within the core code, but being able to artifically limit the number of bytes which we can mmap at once from pack files will make it easier to craft test cases for the new mmap sliding window implementation.

* UTF-8: introduce i18n.logoutputencoding.Junio C Hamano2006-12-27
| | | | | | | | | | | | | | | | It is plausible for somebody to want to view the commit log in a different encoding from i18n.commitencoding -- the project's policy may be UTF-8 and the user may be using a commit message hook to run iconv to conform to that policy (and either not have i18n.commitencoding to default to UTF-8 or have it explicitly set to UTF-8). Even then, Latin-1 may be more convenient for the usual pager and the terminal the user uses. The new variable i18n.logoutputencoding is used in preference to i18n.commitencoding to decide what encoding to recode the log output in when git-log and friends formats the commit log message.

(1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files.

| | | | | | | | | | | | | | | | | | | | | | | | | | While adding colour to the branch command it was pointed out that a config option like "branch.color" conflicts with the pre-existing "branch.something" namespace used for specifying default merge urls and branches. The suggested solution was to flip the order of the components to "color.branch", which I did for colourising branch. This patch does the same thing for - git-log (color.diff) - git-status (color.status) - git-diff (color.diff) - pager (color.pager) I haven't removed the old config options; but they should probably be deprecated and eventually removed to prevent future namespace collisions. I've done this deprecation by changing the documentation for the config file to match the new names; and adding the "color.XXX" options to contrib/completion/git-completion.bash. Unfortunately git-svn reads "diff.color" and "pager.color"; which I don't like to change unilaterally.

* sha1_file: add the ability to parse objects in "pack file format"Linus Torvalds2006-07-13
| | | | | | | | | | | | | | | | | | | The pack-file format is slightly different from the traditional git object format, in that it has a much denser binary header encoding. The traditional format uses an ASCII string with type and length information, which is somewhat wasteful. A new object format starts with uncompressed binary header followed by compressed payload -- this will allow us later to copy the payload straight to packfiles. Obviously they cannot be read by older versions of git, so for now new object files are created with the traditional format. core.legacyheaders configuration item, when set to false makes the code write in new format for people to experiment with.

The speed difference is even more noticeable when committing large files, which is now up to 8 times faster. The configurability is through setting core.compression = [-1..9] which maps to the zlib constants; -1 is the default, 0 is no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest.

* shared repository - add a few missing calls to adjust_shared_perm().Junio C Hamano2006-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | There were a few calls to adjust_shared_perm() that were missing: - init-db creates refs, refs/heads, and refs/tags before reading from templates that could specify sharedrepository in the config file; - updating config file created it under user's umask without adjusting; - updating refs created it under user's umask without adjusting; - switching branches created .git/HEAD under user's umask without adjusting. This moves adjust_shared_perm() from sha1_file.c to path.c, since a few SIMPLE_PROGRAM need to call repository configuration functions which in turn need to call adjust_shared_perm(). sha1_file.c needs to link with SHA1 computation library which is usually not linked to SIMPLE_PROGRAM.

* git config syntax updatesLinus Torvalds2006-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the hierarchical section name syntax to [section<space>+"<randomstring>"] where the only rule for "randomstring" is that it can't contain a newline, and if you really want to insert a double-quote, you do it with \". It turns that into the section name "secion.randomstring". The "section" part is still case insensitive, but the "randomstring" part is case sensitive. So you could use this for things like [email "torvalds@osdl.org"] name = Linus Torvalds if you wanted to do the "email->name" conversion as part of the config file format (I'm not claiming that is sensible, I'm just giving it as an insane example). That would show up as the association email.torvalds@osdl.org.name -> Linus Torvalds which is easy to parse (the "." in the email _looks_ ambiguous, but it isn't: you know that there will always be a single key-name, so you find the key name with "strrchr(name, '.')" and things are entirely unambiguous). Repo-config is updated to be able to parse the new format, and also write things out in the new format. [jc: rolled two patches from Linus and one fix-up from Sean into one, with additional adjustments for t/t1300 test to check the case insensitiveness of section base and variable and case sensitiveness of the extended section part.

* "Assume unchanged" gitJunio C Hamano2006-02-08

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>
