2018-05-29help: add --config to list all available configLibravatar Nguyễn Thái Ngọc Duy1-0/+3
Sometimes it helps to list all available config vars so the user can search for something they want. The config man page can also be used but it's harder to search if you want to focus on the variable name, for example. This is not the best way to collect the available config since it's not precise. Ideally we should have a centralized list of config in C code (pretty much like 'struct option'), but that's a lot more work. This will do for now.

2018-05-29Add and use generic name->id mapping code for color slot parsingLibravatar Nguyễn Thái Ngọc Duy1-32/+21
Instead of hard coding the name-to-id mapping in C code, keep it in an array and use a common function to do the parsing. This reduces code and also allows us to list all possible color slots later.

2018-05-16object-store: move object access functions to object-store.hLibravatar Stefan Beller1-0/+1
This should make these functions easier to find and cache.h less overwhelming to read. In particular, this moves: - read_object_file - oid_object_info - write_object_file As a result, most of the codebase needs to #include object-store.h. In this patch the #include is only added to files that would fail to compile otherwise. It would be better to #include wherever identifiers from the header are used. That can happen later when we have better tooling for it. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-05-06Replace all die("BUG: ...") calls by BUG() onesLibravatar Johannes Schindelin1-6/+6
In d8193743e08 (usage.c: add BUG() function, 2017-05-12), a new macro was introduced to use for reporting bugs instead of die(). It was then subsequently used to convert one single caller in 588a538ae55 (setup_git_env: convert die("BUG") to BUG(), 2017-05-12). The cover letter of the patch series containing this patch (cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not terribly clear why only one call site was converted, or what the plan is for other, similar calls to die() to report bugs. Let's just convert all remaining ones in one fell swoop.

2018-02-27diff: add --compact-summaryLibravatar Nguyễn Thái Ngọc Duy1-0/+37
Certain information is currently shown with --summary, but when used in combination with --stat it's a bit hard to read since info of the same file is in two places (--stat and --summary). On top of that, commits that add or remove files double the number of display lines, which could be a lot if you add or remove a lot of files. --compact-summary embeds most of --summary back in --stat in the little space between the file name part and the graph line, e.g. with commit 0433d533f1: Documentation/merge-config.txt | 4 + builtin/merge.c | 2 + ...-pull-verify-signatures.sh (new +x) | 81 ++++++++++++++ t/t7612-merge-verify-signatures.sh | 45 ++++++++ 4 files changed, 132 insertions(+) It helps both condensing information and saving some text space. What's new in diffstat is: - A new 0644 file is shown as (new) - A new 0755 file is shown as (new +x) - A new symlink is shown as (new +l) - A deleted file is shown as (gone) - A mode change adding executable bit is shown as (mode +x) - A mode change removing it is shown as (mode -x) Note that --compact-summary does not contain all the information --summary provides.

2018-02-02diff.c: refactor pprint_rename() to use strbufLibravatar Nguyễn Thái Ngọc Duy1-33/+26
Instead of passing char* around, let function handle strbuf directly. All callers already use strbuf internally. This helps kill the "not free" exception in free_diffstat_info(). I don't think this code is so critical that we need to avoid some free() calls. The other benefit comes in the next patch, where we append something in pname before returning from fill_print_name(). With strbuf, it's very simple. With "char *" we may have to resort to explicit reallocation and stuff.

2018-01-16convert_to_git(): safe_crlf/checksafe becomes int conv_flagsLibravatar Torsten Bögershausen1-4/+4
When calling convert_to_git(), the checksafe parameter defined what should happen if the EOL conversion (CRLF --> LF --> CRLF) does not roundtrip cleanly. In addition, it also defined if line endings should be renormalized (CRLF --> LF) or kept as they are. checksafe was an safe_crlf enum with these values: SAFE_CRLF_FALSE: do nothing in case of EOL roundtrip errors SAFE_CRLF_FAIL: die in case of EOL roundtrip errors SAFE_CRLF_WARN: print a warning in case of EOL roundtrip errors SAFE_CRLF_RENORMALIZE: change CRLF to LF SAFE_CRLF_KEEP_CRLF: keep all line endings as they are In some cases the integer value 0 was passed as checksafe parameter instead of the correct enum value SAFE_CRLF_FALSE. That was no problem because SAFE_CRLF_FALSE is defined as 0. FALSE/FAIL/WARN are different from RENORMALIZE and KEEP_CRLF. Therefore, an enum is not ideal. Let's use a integer bit pattern instead and rename the parameter to conv_flags to make it more generically usable. This allows us to extend the bit pattern in a subsequent commit.

2018-01-04diffcore: add a pickaxe option to find a specific blobLibravatar Stefan Beller1-1/+20
Sometimes users are given a hash of an object and they want to identify it further (ex.: Use verify-pack to find the largest blobs, but what are these? or [1]) One might be tempted to extend git-describe to also work with blobs, such that `git describe <blob-id>` gives a description as '<commit-ish>:<path>'. This was implemented at [2]; as seen by the sheer number of responses (>110), it turns out this is tricky to get right. The hard part to get right is picking the correct 'commit-ish' as that could be the commit that (re-)introduced the blob or the blob that removed the blob; the blob could exist in different branches. Junio hinted at a different approach of solving this problem, which this patch implements. Teach the diff machinery another flag for restricting the information to what is shown. For example: $ ./git log --oneline --find-object=v2.0.0:Makefile b2feb64309 Revert the whole "ask curl-config" topic for now 47fbfded53 i18n: only extract comments marked with "TRANSLATORS:" we observe that the Makefile as shipped with 2.0 was appeared in v1.9.2-471-g47fbfded53 and in v2.0.0-rc1-5-gb2feb6430b. The reason why these commits both occur prior to v2.0.0 are evil merges that are not found using this new mechanism.

2018-01-04diff: introduce DIFF_PICKAXE_KINDS_MASKLibravatar Stefan Beller1-2/+2
Currently the check whether to perform pickaxing is done via checking `diffopt->pickaxe`, which contains the command line argument that we want to pickaxe for. Soon we'll introduce a new type of pickaxing, that will not store anything in the `.pickaxe` field, so let's migrate the check to be dependent on pickaxe_opts. It is not enough to just replace the check for pickaxe by pickaxe_opts, because flags might be set, but pickaxing was not requested ('-i').

A follow-up patch (series) will rectify the situation by covering the new output format as well as the backward compatible one. Also, fix a typo: "abbbreviated" ---> "abbreviated".

2017-11-28diff: support anchoring line(s)Libravatar Jonathan Tan1-2/+20
Teach diff a new algorithm, one that attempts to prevent user-specified lines from appearing as a deletion or addition in the end result. The end user can use this by specifying "--anchored=<text>" one or more times when using Git commands like "diff" and "show".

The "diff" family of commands learned to ignore differences in carriage return at the end of line. * jc/ignore-cr-at-eol: diff: --ignore-cr-at-eol xdiff: reassign xpparm_t.flags bits
2017-11-15diff: remove silent clamp of renameLimitLibravatar Elijah Newren1-1/+1
In commit 0024a5492 (Fix the rename detection limit checking; 2007-09-14), the renameLimit was clamped to 32767. This appears to have been to simply avoid integer overflow in the following computation: num_create * num_src <= rename_limit * rename_limit although it also could be viewed as a hardcoded bound on the amount of CPU time we're willing to allow users to tell git to spend on handling renames. An upper bound may make sense, but unfortunately this upper bound was neither communicated to the users, nor documented anywhere. Although large limits can make things slow, we have users who would be ecstatic to have a small five file change be correctly cherry picked even if they have to manually specify a large limit and wait ten minutes for the renames to be detected.

2017-11-09Merge branch 'ao/diff-populate-filespec-lstat-errorpath-fix'Libravatar Junio C Hamano1-8/+6
After an error from lstat(), diff_populate_filespec() function sometimes still went ahead and used invalid data in struct stat, which has been fixed. * ao/diff-populate-filespec-lstat-errorpath-fix: diff: fix lstat() error handling in diff_populate_filespec()
2017-11-08diff: --ignore-cr-at-eolLibravatar Junio C Hamano1-0/+2
A new option --ignore-cr-at-eol tells the diff machinery to treat a carriage-return at the end of a (complete) line as if it does not exist. Just like other "--ignore-*" options to ignore various kinds of whitespace differences, this will help reviewing the real changes you made without getting distracted by spurious CRLF<->LF conversion made by your editor program.
