2019-01-23commit-graph write: more descriptive "writing out" outputLibravatar Ævar Arnfjörð Bjarmason1-2/+10
Make the "Writing out" part of the progress output more descriptive. Depending on the shape of the graph we either make 3 or 4 passes over it. Let's present this information to the user in case they're wondering what this number, which is much larger than their number of commits, has to do with writing out the commit graph. Now e.g. on linux.git we emit: $ ~/g/git/git --exec-path=$HOME/g/git -C ~/g/linux commit-graph write Finding commits for commit graph: 6529159, done. Expanding reachable commits in commit graph: 815990, done. Computing commit graph generation numbers: 100% (815983/815983), done. Writing out commit graph in 4 passes: 100% (3263932/3263932), done. A note on i18n: Why are we using the Q_() function and passing a number & English text for a singular which'll never be used? Because the plural rules of translated languages may not match those of English, and to use the plural function we need to use this format.

2019-01-23commit-graph write: add "Writing out" progress outputLibravatar Ævar Arnfjörð Bjarmason1-9/+30
Add progress output to be shown when we're writing out the commit-graph, this adds to the output already added in 7b0f229222 ("commit-graph write: add progress output", 2018-09-17). As noted in that commit most of the progress output isn't displayed on small repositories, but before this change we'd noticeably hang for 2-3 seconds at the end on medium sized repositories such as linux.git. Now we'll instead show output like this, and reduce the human-observable times at which we're not producing progress output: $ ~/g/git/git --exec-path=$HOME/g/git -C ~/g/2015-04-03-1M-git commit-graph write Finding commits for commit graph: 13064614, done. Expanding reachable commits in commit graph: 1000447, done. Computing commit graph generation numbers: 100% (1000447/1000447), done. Writing out commit graph: 100% (3001341/3001341), done. This "Writing out" number is 3x or 4x the number of commits, depending on the graph we're processing. A later change will make this explicit to the user.

2019-01-23commit-graph: don't call write_graph_chunk_extra_edges() unnecessarilyLibravatar SZEDER Gábor1-1/+2
The optional 'Extra Edge List' chunk of the commit graph file stores parent information for commits with more than two parents. Since the chunk is optional, write_commit_graph() looks through all commits to find those with more than two parents, and then writes the commit graph file header accordingly, i.e. if there are no such commits, then there won't be a 'Extra Edge List' chunk written, only the three mandatory chunks. However, when it later comes to writing actual chunk data, write_commit_graph() unconditionally invokes write_graph_chunk_extra_edges(), even when it was decided earlier that that chunk won't be written. Strictly speaking there is no bug here, because write_graph_chunk_extra_edges() won't write anything if it doesn't find any commits with more than two parents, but then it unnecessarily and in vain looks through all commits once again in search for such commits. Don't call write_graph_chunk_extra_edges() when that chunk won't be written to spare an unnecessary iteration over all commits.

2019-01-22commit-graph: rename "large edges" to "extra edges"Libravatar SZEDER Gábor5-24/+24
The optional 'Large Edge List' chunk of the commit graph file stores parent information for commits with more than two parents, and the names of most of the macros, variables, struct fields, and functions related to this chunk contain the term "large edges", e.g. write_graph_chunk_large_edges(). However, it's not a really great term, as the edges to the second and subsequent parents stored in this chunk are not any larger than the edges to the first and second parents stored in the "main" 'Commit Data' chunk. It's the number of edges, IOW number of parents, that is larger compared to non-merge and "regular" two-parent merge commits. And indeed, two functions in 'commit-graph.c' have a local variable called 'num_extra_edges' that refer to the same thing, and this "extra edges" term is much better at describing these edges. So let's rename all these references to "large edges" in macro, variable, function, etc. names to "extra edges". There is a GRAPH_OCTOPUS_EDGES_NEEDED macro as well; for the sake of consistency rename it to GRAPH_EXTRA_EDGES_NEEDED. We can do so safely without causing any incompatibility issues, because the term "large edges" doesn't come up in the file format itself in any form (the chunk's magic is {'E', 'D', 'G', 'E'}, there is no 'L' in there), but only in the specification text. The string "large edges", however, does come up in the output of 'git commit-graph read' and in tests looking at its input, but that command is explicitly documented as debugging aid, so we can change its output and the affected tests safely.

2019-01-22commit-graph write: use pack order when finding commitsLibravatar Ævar Arnfjörð Bjarmason1-2/+4
Slightly optimize the "commit-graph write" step by using FOR_EACH_OBJECT_PACK_ORDER with for_each_object_in_pack(). See commit [1] and [2] for the facility and a similar optimization for "cat-file". On Linux it is around 5% slower to run: echo 1 >/proc/sys/vm/drop_caches && cat .git/objects/pack/* >/dev/null && git cat-file --batch-all-objects --batch-check --unordered Than the same thing with the "cat" omitted. This is as expected, since we're iterating in pack order and the "cat" is extra work. Before this change the opposite was true of "commit-graph write". We were 6% faster if we first ran "cat" to efficiently populate the FS cache for our sole big pack on linux.git, than if we had populated it via for_each_object_in_pack(). Now we're 3% faster without the "cat" instead. My tests were done on an unloaded Linux 3.10 system with 10 runs for each. Derrick Stolee did his own tests on Windows[3] showing a 2% improvement with a high degree of accuracy. 1. 736eb88fdc ("for_each_packed_object: support iterating in pack-order", 2018-08-10) 2. 0750bb5b51 ("cat-file: support "unordered" output for --batch-all-objects", 2018-08-10) 3. https://public-inbox.org/git/f71fa868-25e8-a9c9-46a6-611b987f1a8f@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-12-26git clone <url> C:\cygwin\home\USER\repo' is working (again)Libravatar Torsten Bögershausen9-72/+54
A regression for cygwin users was introduced with commit 05b458c, "real_path: resolve symlinks by hand". In the the commit message we read: The current implementation of real_path uses chdir() in order to resolve symlinks. Unfortunately this isn't thread-safe as chdir() affects a process as a whole... The old (and non-thread-save) OS calls chdir()/pwd() had been replaced by a string operation. The cygwin layer "knows" that "C:\cygwin" is an absolute path, but the new string operation does not. "git clone <url> C:\cygwin\home\USER\repo" fails like this: fatal: Invalid path '/home/USER/repo/C:\cygwin\home\USER\repo' The solution is to implement has_dos_drive_prefix(), skip_dos_drive_prefix() is_dir_sep(), offset_1st_component() and convert_slashes() for cygwin in the same way as it is done in 'Git for Windows' in compat/mingw.[ch] Extract the needed code into compat/win32/path-utils.[ch] and use it for cygwin as well.

2018-12-26log -G: ignore binary filesLibravatar Thomas Braun4-1/+48
The -G<regex> option of log looks for the differences whose patch text contains added/removed lines that match regex. Currently -G looks also into patches of binary files (which according to [1]) is binary as well. This has a couple of issues: - It makes the pickaxe search slow. In a proprietary repository of the author with only ~5500 commits and a total .git size of ~300MB searching takes ~13 seconds $time git log -Gwave > /dev/null real 0m13,241s user 0m12,596s sys 0m0,644s whereas when we ignore binary files with this patch it takes ~4s $time ~/devel/git/git log -Gwave > /dev/null real 0m3,713s user 0m3,608s sys 0m0,105s which is a speedup of more than fourfold. - The internally used algorithm for generating patch text is based on xdiff and its states in [1] > The output format of the binary patch file is proprietary > (and binary) and it is basically a collection of copy and insert > commands [..] which means that the current format could change once the internal algorithm is changed as the format is not standardized. In addition the git binary patch format used for preparing patches for git apply is *different* from the xdiff format as can be seen by comparing git log -p -a commit 6e95bf4bafccf14650d02ab57f3affe669be10cf Author: A U Thor <author@example.com> Date: Thu Apr 7 15:14:13 2005 -0700 modify binary file diff --git a/data.bin b/data.bin index f414c84..edfeb6f 100644 --- a/data.bin +++ b/data.bin @@ -1,2 +1,4 @@ a a^@a +a +a^@a with git log --binary commit 6e95bf4bafccf14650d02ab57f3affe669be10cf Author: A U Thor <author@example.com> Date: Thu Apr 7 15:14:13 2005 -0700 modify binary file diff --git a/data.bin b/data.bin index f414c84bd3aa25fa07836bb1fb73db784635e24b..edfeb6f501[..] GIT binary patch literal 12 QcmYe~N@Pgn0zx1O01)N^ZvX%Q literal 6 NcmYe~N@Pgn0ssWg0XP5v which seems unexpected.

The -S<block of text> option of log looks for differences that changes the number of occurrences of the specified block of text (i.e. addition/deletion) in a file. As we want to keep the current behaviour, add a test to ensure it stays that way.

The new test_oid machinery in the test library requires reading some information from t/oid-info/hash-info and t/oid-info/oid. The logic to read from these files in shell uses built-in "read" command, which leaves CR at the end of these text files when they are checked out with CRLF line endings, at least when run with bash shipped with Git for Windows. This results in an unexpected value in the variable these lines are read into, leading the tests to fail. Mark them to be checked out always with the LF line endings.
