* utils: move trace to utilsAyman Bagabas2023-11-162-0/+150
| | | | | | | Without exposing `trace`, we can't set a target to enable tracing from out of go-git. Fixes: https://github.com/go-git/go-git/pull/916
* utils: remove ioutil.Pipe and use std library io.PipeAyman Bagabas2023-11-133-29/+1
| | | | ioutil.Pipe literally calls io.Pipe.

* Optimize zlib reader and consolidate sync.poolsPaulo Gomes2022-11-076-0/+303
| | | | | | | | | | | | | | | | | | | Expands on the optimisations from https://github.com/fluxcd/go-git/pull/5 and ensures that zlib reader does not need to recreate a deflate dictionary at every use. The use of sync pools was consolidated into a new sync utils package. name old time/op new time/op delta Parser-16 7.51ms ± 3% 7.71ms ± 6% ~ (p=0.222 n=5+5) name old alloc/op new alloc/op delta Parser-16 4.65MB ± 3% 1.90MB ± 3% -59.06% (p=0.008 n=5+5) name old allocs/op new allocs/op delta Parser-16 3.48k ± 0% 3.32k ± 0% -4.57% (p=0.016 n=5+4) Signed-off-by: Paulo Gomes <pjbgf@linux.com>

| | | | | | | | | | | | | | | | [staticcheck](https://staticcheck.io/) reported a number of unused fields, functions, types, and variables across the code. Where possible, use them (assert unchecked errors in tests, for example) and otherwise remove them.
* | simplified sparse checkoutJohn Cai2021-11-098-3/+55
|/ | | | | | | | | This is the initial logic to support a simple sparse checkout where directories to be included can be specified in CheckoutOptions. This change doesn't fully support the sparse patterns, nor does this change include the optimization to collapse flie entries in ithe index that are excluded via the sparse checkout directory patterns included under the parent directory.
* plumbing: format/packfile, prevent large objects from being read into memory ↵zeripath2021-06-301-0/+40
| | | | | | | | | | | | | | | completely (#330) This PR adds code to prevent large objects from being read into memory from packfiles or the filesystem. Objects greater than 1Mb are now no longer directly stored in the cache or read completely into memory. This PR differs and improves the previous broken #323 by fixing several bugs in the reader and transparently wrapping ReaderAt as a Reader. Signed-off-by: Andrew Thornton <art27@cantab.net>

* plumbing: detect renames by hash and similar content in diff treeMiguel Molina2020-04-231-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit implements the rename detection algorithms used in the JGit implementation. Given a list of changes, additions and deletions are extracted and matched in two ways: - By exact hash content: all additions and deletions are grouped by the content hash and paired with the best match based on the file mode and file path. All the files that cannot be paired are kept as regular deletions and additions. - By similar content: a matrix of addition and deletion pairs with all possible combinations is created and scored by how similar the content is between both files as well as how similar the file path is. The pairs with the best score and whose score is equal or greater than a threshold are paired and turned into a rename. All the files that cannot be paired are kept as regular deletions and additions. DiffTree and DiffTreeContext will not return the changes with renames detected for compatibility reasons, although this will change in v6 so that detecting renames is the default behaviour. A new function DiffTreeWithOptions has been added to configure the parameters for the rename detection to control the score threshold, the limit of renames and whether to use similar content detection in the detection.

| | | | | | | | | Some multibyte characters can have multiple representations. Before comparing strings, we need to normalize them. In this case we're normalizing to normalized form C, but it shouldn't matter as long as both strings are normalized to the same form. Fixes https://github.com/src-d/go-git/issues/495
