Don't expand CRLFs when normalizing text during merge

2010-07-02T22:45:18Z

Disable CRLF expansion when convert_to_working_tree() is called from normalize_buffer(). This improves performance when merging branches with conflicting line endings when core.eol=crlf or core.autocrlf=true by making the normalization act as if core.eol=lf.

Avoid conflicts when merging branches with mixed normalization

2010-07-02T22:43:15Z

Currently, merging across changes in line ending normalization is painful since files containing CRLF will conflict with normalized files, even if the only difference between the two versions is the line endings. Additionally, any "real" merge conflicts that exist are obscured because every line in the file has a conflict. Assume you start out with a repo that has a lot of text files with CRLF checked in (A): o---C / \ A---B---D B: Add "* text=auto" to .gitattributes and normalize all files to LF-only C: Modify some of the text files D: Try to merge C You will get a ridiculous number of LF/CRLF conflicts when trying to merge C into D, since the repository contents for C are "wrong" wrt the new .gitattributes file. Fix ll-merge so that the "base", "theirs" and "ours" stages are passed through convert_to_worktree() and convert_to_git() before a three-way merge. This ensures that all three stages are normalized in the same way, removing from consideration differences that are only due to normalization. This feature is optional for now since it changes a low-level mechanism and is not necessary for the majority of users. The "merge.renormalize" config variable enables it.

Add "core.eol" config variable

2010-06-07T04:20:04Z

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". Signed-off-by: Eyvind Bernhardsen Signed-off-by: Junio C Hamano

Rewrite dynamic structure initializations to runtime assignment

2010-05-31T23:59:26Z

Unfortunately, there are still plenty of production systems with vendor compilers that choke unless all compound declarations can be determined statically at compile time, for example hpux10.20 (I can provide a comprehensive list of our supported platforms that exhibit this problem if necessary). This patch simply breaks apart any compound declarations with dynamic initialisation expressions, and moves the initialisation until after the last declaration in the same block, in all the places necessary to have the offending compilers accept the code.

Rename the "crlf" attribute "text"

2010-05-20T03:42:34Z

As discussed on the list, "crlf" is not an optimal name. Linus suggested "text", which is much better. Signed-off-by: Eyvind Bernhardsen Signed-off-by: Junio C Hamano

Add per-repository eol normalization

2010-05-20T03:36:15Z

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. Signed-off-by: Eyvind Bernhardsen Signed-off-by: Junio C Hamano

autocrlf: Make it work also for un-normalized repositories

2010-05-12T06:02:49Z

Previously, autocrlf would only work well for normalized repositories. Any text files that contained CRLF in the repository would cause problems, and would be modified when handled with core.autocrlf set. Change autocrlf to not do any conversions to files that in the repository already contain a CR. git with autocrlf set will never create such a file, or change a LF only file to contain CRs, so the (new) assumption is that if a file contains a CR, it is intentional, and autocrlf should not change that. The following sequence should now always be a NOP even with autocrlf set (assuming a clean working directory): git checkout touch * git add -A . (will add nothing) git commit (nothing to commit) Previously this would break for any text file containing a CR. Some of you may have been folowing Eyvind's excellent thread about trying to make end-of-line translation in git a bit smoother. I decided to attack the problem from a different angle: Is it possible to make autocrlf behave non-destructively for all the previous problem cases? Stealing the problem from Eyvind's initial mail (paraphrased and summarized a bit): 1. Setting autocrlf globally is a pain since autocrlf does not work well with CRLF in the repo 2. Setting it in individual repos is hard since you do it "too late" (the clone will get it wrong) 3. If someone checks in a file with CRLF later, you get into problems again 4. If a repository once has contained CRLF, you can't tell autocrlf at which commit everything is sane again 5. autocrlf does needless work if you know that all your users want the same EOL style. I belive that this patch makes autocrlf a safe (and good) default setting for Windows, and this solves problems 1-4 (it solves 2 by being set by default, which is early enough for clone). I implemented it by looking for CR charactes in the index, and aborting any conversion attempt if this is found. Signed-off-by: Finn Arne Gangstad Signed-off-by: Junio C Hamano
