2017-11-17add: introduce "--renormalize"Libravatar Torsten Bögershausen1-2/+4
Make it safer to normalize the line endings in a repository. Files that had been commited with CRLF will be commited with LF. The old way to normalize a repo was like this: # Make sure that there are not untracked files $ echo "* text=auto" >.gitattributes $ git read-tree --empty $ git add . $ git commit -m "Introduce end-of-line normalization" The user must make sure that there are no untracked files, otherwise they would have been added and tracked from now on. The new "add --renormalize" does not add untracked files: $ echo "* text=auto" >.gitattributes $ git add --renormalize . $ git commit -m "Introduce end-of-line normalization" Note that "git add --renormalize <pathspec>" is the short form for "git add -u --renormalize <pathspec>". While at it, document that the same renormalization may be needed, whenever a clean filter is added or changed.

2017-06-30convert: add "status=delayed" to filter process protocolLibravatar Lars Schneider1-4/+65
Some `clean` / `smudge` filters may require a significant amount of time to process a single blob (e.g. the Git LFS smudge filter might perform network requests). During this process the Git checkout operation is blocked and Git needs to wait until the filter is done to continue with the checkout. Teach the filter process protocol, introduced in edcc8581 ("convert: add filter.<driver>.process option", 2016-10-16), to accept the status "delayed" as response to a filter request. Upon this response Git continues with the checkout operation. After the checkout operation Git calls "finish_delayed_checkout" which queries the filter for remaining blobs. If the filter is still working on the completion, then the filter is expected to block. If the filter has completed all remaining blobs then an empty response is expected. Git has a multiple code paths that checkout a blob. Support delayed checkouts only in `clone` (in unpack-trees.c) and `checkout` operations for now. The optimization is most effective in these code paths as all files of the tree are processed.

2017-06-15doc: do not use `rm .git/index` when normalizing line endingsLibravatar Andreas Heiduk1-1/+1
When illustrating how to normalize the line endings, the documentation in gitattributes tells the user to `rm .git/index`. This is incorrect for two reasons: - Users shouldn't be instructed to mess around with the internal implementation of Git using raw file system tools like `rm`. - Within a submodule or an additional working tree `.git` is just a file containing a `gitdir: <path>` pointer into the real `.git` directory. Therefore `rm .git/index` does not work. The purpose of the `rm .git/index` instruction is to remove all entries from the index without touching the working tree. The way to do this with Git is to use `read-tree --empty`.

2016-10-17convert: add filter.<driver>.process optionLibravatar Lars Schneider1-1/+154
Git's clean/smudge mechanism invokes an external filter process for every single blob that is affected by a filter. If Git filters a lot of blobs then the startup time of the external filter processes can become a significant part of the overall Git execution time. In a preliminary performance test this developer used a clean/smudge filter written in golang to filter 12,000 files. This process took 364s with the existing filter mechanism and 5s with the new mechanism. See details here: https://github.com/github/git-lfs/pull/1382 This patch adds the `filter.<driver>.process` string option which, if used, keeps the external filter process running and processes all blobs with the packet format (pkt-line) based protocol over standard input and standard output. The full protocol is explained in detail in `Documentation/gitattributes.txt`. A few key decisions: * The long running filter process is referred to as filter protocol version 2 because the existing single shot filter invocation is considered version 1. * Git sends a welcome message and expects a response right after the external filter process has started. This ensures that Git will not hang if a version 1 filter is incorrectly used with the filter.<driver>.process option for version 2 filters. In addition, Git can detect this kind of error and warn the user. * The status of a filter operation (e.g. "success" or "error) is set before the actual response and (if necessary!) re-set after the response. The advantage of this two step status response is that if the filter detects an error early, then the filter can communicate this and Git does not even need to create structures to read the response. * All status responses are pkt-line lists terminated with a flush packet. This allows us to send other status fields with the same protocol in the future.

2016-06-03userdiff: add built-in pattern for CSSLibravatar William Duclot1-0/+2
CSS is widely used, motivating it being included as a built-in pattern. It must be noted that the word_regex for CSS (i.e. the regex defining what is a word in the language) does not consider '.' and '#' characters (in CSS selectors) to be part of the word. This behavior is documented by the test t/t4018/css-rule. The logic behind this behavior is the following: identifiers in CSS selectors are identifiers in a HTML/XML document. Therefore, the '.'/'#' character are not part of the identifier, but an indicator of the nature of the identifier in HTML/XML (class or id). Diffing ".class1" and ".class2" must show that the class name is changed, but we still are selecting a class. Logic behind the "pattern" regex is: 1. reject lines ending with a colon/semicolon (properties) 2. if a line begins with a name in column 1, pick the whole line Credits to Johannes Sixt (j6t@kdbg.org) for the pattern regex and most of the tests.

2015-06-04ll-merge: pass the original path to external driversLibravatar Junio C Hamano1-1/+4
The interface to custom low-level merge driver was modeled to be capable of driving programs like "merge" (from the RCS suite) that can produce result solely by looking at three files that hold contents of common ancestor, ours and theirs. The information we feed to the external drivers via the command line placeholders %O, %A, and %B were designed to be purely about contents by giving names of the temporary files that hold these variants without exposing the original pathname. No matter where the result goes, merging the same three variants should produce the same result, contents is the king, that is the Git way. The external driver interface, however, is meant to help people to step outside the Git worldview, and sometimes people want to know the final path that the resulting merged contents would be stored in.

Over the years, ignore's implementation accumulates more optimizations while attr's stays the same.

2012-02-17Add a setting to require a filter to be successfulLibravatar Jehan Bing1-10/+31
By default, a missing filter driver or a failure from the filter driver is not an error, but merely makes the filter operation a no-op pass through. This is useful to massage the content into a shape that is more convenient for the platform, filesystem, and the user to use, and the content filter mechanism is not used to turn something unusable into usable. However, we could also use of the content filtering mechanism and store the content that cannot be directly used in the repository (e.g. a UUID that refers to the true content stored outside git, or an encrypted content) and turn it into a usable form upon checkout (e.g. download the external content, or decrypt the encrypted content). For such a use case, the content cannot be used when filter driver fails, and we need a way to tell Git to abort the whole operation for such a failing or missing filter driver. Add a new "filter.<driver>.required" configuration variable to mark the second use case. When it is set, git will abort the operation when the filter driver does not exist or exits with a non-zero status code.
