* eb/core-eol: Add "core.eol" config variable Rename the "crlf" attribute "text" Add per-repository eol normalization Add tests for per-repository eol normalization Conflicts: Documentation/config.txt Makefile
2010-06-06Add "core.eol" config variableLibravatar Eyvind Bernhardsen1-0/+1
Introduce a new configuration variable, "core.eol", that allows the user to set which line endings to use for end-of-line-normalized files in the working directory. It defaults to "native", which means CRLF on Windows and LF everywhere else. Note that "core.autocrlf" overrides core.eol. This means that [core] autocrlf = true puts CRLFs in the working directory even if core.eol is set to "lf".

2010-05-19Add per-repository eol normalizationLibravatar Eyvind Bernhardsen1-1/+1
Change the semantics of the "crlf" attribute so that it enables end-of-line normalization when it is set, regardless of "core.autocrlf". Add a new setting for "crlf": "auto", which enables end-of-line conversion but does not override the automatic text file detection. Add a new attribute "eol" with possible values "crlf" and "lf". When set, this attribute enables normalization and forces git to use CRLF or LF line endings in the working directory, respectively. The line ending style to be used for normalized text files in the working directory is set using "core.autocrlf". When it is set to "true", CRLFs are used in the working directory; when set to "input" or "false", LFs are used.

2010-02-24Refactor list of of repo-local env varsLibravatar Giuseppe Bilotta1-0/+17
Move the list of GIT_* environment variables that are local to a repository into a static list in environment.c, as it is also useful elsewhere. Also add the missing GIT_CONFIG variable to the list. Make it easy to use the list both by NULL-termination and by size; the latter (excluding the terminating NULL) is stored in the local_repo_env_size define.

2009-11-20replace: use a GIT_NO_REPLACE_OBJECTS env variableLibravatar Christian Couder1-0/+2
This has the same effect as --no-replace-objects option; git ignores the replace refs. When --no-replace-objects option is passed to git, this environment variable is set to "1" and exported to subprocesses in order to propagate the same setting. It is useful for example for scripts, as the git commands used in them can now be aware that they must not read replace refs.

2009-10-19Introduce commit notesLibravatar Johannes Schindelin1-0/+1
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

2009-07-24git repack: keep commits hidden by a graftLibravatar Johannes Schindelin1-0/+1
When you have grafts that pretend that a given commit has different parents than the ones recorded in the commit object, it is dangerous to let 'git repack' remove those hidden parents, as you can easily remove the graft and end up with a broken repository. So let's play it safe and keep those parent objects and everything that is reachable by them, in addition to the grafted parents. As this behavior can only be triggered by git pack-objects, and as that command handles duplicate parents gracefully, we do not bother to cull duplicated parents that may result by using both true and grafted parents.

2009-04-25Add an option not to use link(src, dest) && unlink(src) when that is unreliableLibravatar Johannes Schindelin1-0/+4
It seems that accessing NTFS partitions with ufsd (at least on my EeePC) has an unnerving bug: if you link() a file and unlink() it right away, the target of the link() will have the correct size, but consist of NULs. It seems as if the calls are simply not serialized correctly, as single-stepping through the function move_temp_to_file() works flawlessly. As ufsd is "Commertial software" (sic!), I cannot fix it, and have to work around it in Git. At the same time, it seems that this fixes msysGit issues 222 and 229 to assume that Windows cannot handle link() && unlink().

2009-03-17New config push.default to decide default behavior for pushLibravatar Finn Arne Gangstad1-0/+1
When "git push" is not told what refspecs to push, it pushes all matching branches to the current remote. For some workflows this default is not useful, and surprises new users. Some have even found that this default behaviour is too easy to trigger by accident with unwanted consequences. Introduce a new configuration variable "push.default" that decides what action git push should take if no refspecs are given or implied by the command line arguments or the current remote configuration. Possible values are: 'nothing' : Push nothing; 'matching' : Current default behaviour, push all branches that already exist in the current remote; 'tracking' : Push the current branch to whatever it is tracking; 'current' : Push the current branch to a branch of the same name, i.e. HEAD.

2008-11-14Add cache preload facilityLibravatar Linus Torvalds1-0/+3
This can do the lstat() storm in parallel, giving potentially much improved performance for cold-cache cases or things like NFS that have weak metadata caching. Just use "read_cache_preload()" instead of "read_cache()" to force an optimistic preload of the index stat data.

"git branch" and "git checkout -b" now honor --track option even when the upstream branch is local. Previously --track was silently ignored when forking from a local branch. Also the command did not error out when --track was explicitly asked for but the forked point specified was not an existing branch (i.e. when there is no way to set up the tracking configuration), but now it correctly does. The configuration setting branch.autosetupmerge can now be set to "always", which is equivalent to using --track from the command line.

2008-02-06safecrlf: Add mechanism to warn about irreversible crlf conversionsLibravatar Steffen Prohaska1-0/+1
CRLF conversion bears a slight chance of corrupting data. autocrlf=true will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data. If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell git that this file is binary and git will handle the file appropriately. Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data. This patch adds a mechanism that can either warn the user about an irreversible conversion or can even refuse to convert. The mechanism is controlled by the variable core.safecrlf, with the following values: - false: disable safecrlf mechanism - warn: warn about irreversible conversions - true: refuse irreversible conversions The default is to warn. Users are only affected by this default if core.autocrlf is set. But the current default of git is to leave core.autocrlf unset, so users will not see warnings unless they deliberately chose to activate the autocrlf mechanism. The safecrlf mechanism's details depend on the git command. The general principles when safecrlf is active (not false) are: - we warn/error out if files in the work tree can modified in an irreversible way without giving the user a chance to backup the original file. - for read-only operations that do not modify files in the work tree we do not not print annoying warnings. There are exceptions. Even though... - "git add" itself does not touch the files in the work tree, the next checkout would, so the safety triggers; - "git apply" to update a text file with a patch does touch the files in the work tree, but the operation is about text files and CRLF conversion is about fixing the line ending inconsistencies, so the safety does not trigger; - "git diff" itself does not touch the files in the work tree, it is often run to inspect the changes you intend to next "git add". To catch potential problems early, safety triggers. The concept of a safety check was originally proposed in a similar way by Linus Torvalds. Thanks to Dimitry Potapov for insisting on getting the naked LF/autocrlf=true case right. Signed-off-by: Steffen Prohaska <prohaska@zib.de>
2007-12-11Support GIT_PAGER_IN_USE environment variableLibravatar Jeff King1-1/+0
When deciding whether or not to turn on automatic color support, git_config_colorbool checks whether stdout is a tty. However, because we run a pager, if stdout is not a tty, we must check whether it is because we started the pager. This used to be done by checking the pager_in_use variable. This variable was set only when the git program being run started the pager; there was no way for an external program running git indicate that it had already started a pager. This patch allows a program to set GIT_PAGER_IN_USE to a true value to indicate that even though stdout is not a tty, it is because a pager is being used.

For example, if you have these in the .gitattributes: frotz whitespace nitfol -whitespace xyzzy whitespace=-trailing all types of whitespace problems known to git are noticed in path 'frotz' (i.e. diff shows them in diff.whitespace color, and apply warns about them), no whitespace problem is noticed in path 'nitfol', and the default types of whitespace problems except "trailing whitespace" are noticed for path 'xyzzy'. A project with mixed Python and C might want to have: *.c whitespace *.py whitespace=-indent-with-non-tab in its toplevel .gitattributes file. Signed-off-by: Junio C Hamano <gitster@pobox.com>
