2015-01-13use xstrdup_or_null to replace ternary conditionalsLibravatar Jeff King1-1/+1
This replaces "x ? xstrdup(x) : NULL" with xstrdup_or_null(x). The change is fairly mechanical, with the exception of resolve_refdup, which can eliminate a temporary variable. There are still a few hits grepping for "?.*xstrdup", but these are of slightly different forms and cannot be converted (e.g., "x ? xstrdup(x->foo) : NULL").

2012-11-04reencode_string(): introduce and use same_encoding()Libravatar Junio C Hamano1-1/+1
Callers of reencode_string() that re-encodes a string from one encoding to another all used ad-hoc way to bypass the case where the input and the output encodings are the same. Some did strcmp(), some did strcasecmp(), yet some others when converting to UTF-8 used is_encoding_utf8(). Introduce same_encoding() helper function to make these callers use the same logic. Notably, is_encoding_utf8() has a work-around for common misconfiguration to use "utf8" to name UTF-8 encoding, which does not match "UTF-8" hence strcasecmp() would not consider the same.

2010-11-17git notes merge: Add another auto-resolving strategy: "cat_sort_uniq"Libravatar Johan Herland1-0/+76
This new strategy is similar to "concatenate", but in addition to concatenating the two note candidates, this strategy sorts the resulting lines, and removes duplicate lines from the result. This is equivalent to applying the "cat | sort | uniq" shell pipeline to the two note candidates. This strategy is useful if the notes follow a line-based format where one wants to avoid duplicate lines in the merge result. Note that if either of the note candidates contain duplicate lines _prior_ to the merge, these will also be removed by this merge strategy. The patch also contains tests and documentation for the new strategy. Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-11-17notes.c: Use two newlines (instead of one) when concatenating notesLibravatar Johan Herland1-3/+4
When using combine_notes_concatenate() to concatenate notes, it currently ensures exactly one newline character between the given notes. However, when using builtin/notes.c:create_note() to concatenate notes (e.g. by 'git notes append'), it adds a newline character to the trailing newline of the preceding notes object, thus resulting in _two_ newlines (aka. a blank line) separating contents of the two notes. This patch brings combine_notes_concatenate() into consistency with builtin/notes.c:create_note(), by ensuring exactly _two_ newline characters between concatenated notes. The patch also changes a few notes-related selftests accordingly. Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-11-17notes.h/c: Propagate combine_notes_fn return value to add_note() and beyondLibravatar Johan Herland1-27/+28
The combine_notes_fn functions uses a non-zero return value to indicate failure. However, this return value was converted to a call to die() in note_tree_insert(). Instead, propagate this return value out to add_note(), and return it from there to enable the caller to handle errors appropriately. Existing add_note() callers are updated to die() upon failure, thus preserving the current behaviour. The only exceptions are copy_note() and notes_cache_put() where we are able to propagate the add_note() return value instead.

2010-11-10notes.h/c: Allow combine_notes functions to remove notesLibravatar Johan Herland1-1/+11
Allow combine_notes functions to request that a note be removed, by setting the resulting note SHA1 to null_sha1 (0000000...). For consistency, also teach note_tree_insert() to skip insertion of an empty note (a note with entry->val_sha1 equal to null_sha1) when there is no note to combine it with. In general, an empty note (null_sha1) is treated identically to no note at all, but when adding an empty note where there already exists a non-empty note, we allow the combine_notes function to potentially record a new/changed note. Document this behaviour, and clearly specify how combine_notes functions are expected to handle null_sha1 in input. Before this patch, storing null_sha1s in the notes tree were silently allowed, causing an invalid notes tree (referring to blobs with null_sha1) to be produced by write_notes_tree().

The rule for selecting the candidates for conversion is: if the callback function returns only 0 (the condition for for_each_string_list to exit early), than it can be safely converted to the macro. A notable exception are the callers in builtin/remote.c. If converted, the readability in the file will suffer greately. Besides, the code is not very performance critical (at the moment, at least): it does output formatting of the list of remotes.

2010-02-13Notes API: prune_notes(): Prune notes that belong to non-existing objectsLibravatar Johan Herland1-0/+39
When an object is made unreachable by Git, any notes that annotate that object are not automagically made unreachable, since all notes are always trivially reachable from a notes ref. In order to remove notes for non-existing objects, we therefore need to add functionality for traversing the notes tree and explicitly removing references to notes that annotate non-reachable objects. Thus the notes objects themselves also become unreachable, and are removed by a later garbage collect. prune_notes() performs this traversal (by using for_each_note() internally), and removes the notes in question from the notes tree. Note that the effect of prune_notes() is not persistent unless a subsequent call to write_notes_tree() is made.

2010-02-13Teach notes code to properly preserve non-notes in the notes treeLibravatar Johan Herland1-39/+180
The note tree structure allows for non-note entries to coexist with note entries in a notes tree. Although we certainly expect there to be very few non-notes in a notes tree, we should still support them to a certain degree. This patch teaches the notes code to preserve non-notes when updating the notes tree with write_notes_tree(). Non-notes are not affected by fanout restructuring. For non-notes to be handled correctly, we can no longer allow subtree entries that do not match the fanout structure produced by the notes code itself. This means that fanouts like 4/36, 6/34, 8/32, 4/4/32, etc. are no longer recognized as note subtrees; only 2-based fanouts are allowed (2/38, 2/2/36, 2/2/2/34, etc.). Since the notes code has never at any point _produced_ non-2-based fanouts, it is highly unlikely that this change will cause problems for anyone. The patch also adds some tests verifying the correct handling of non-notes in a notes tree. Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-02-13Refactor notes concatenation into a flexible interface for combining notesLibravatar Johan Herland1-58/+80
When adding a note to an object that already has an existing note, the current solution is to concatenate the contents of the two notes. However, the caller may instead wish to _overwrite_ the existing note with the new note, or maybe even _ignore_ the new note, and keep the existing one. There might also be other ways of combining notes that are only known to the caller. Therefore, instead of unconditionally concatenating notes, we let the caller specify how to combine notes, by passing in a pointer to a function for combining notes. The caller may choose to implement its own function for notes combining, but normally one of the following three conveniently supplied notes combination functions will be sufficient: - combine_notes_concatenate() combines the two notes by appending the contents of the new note to the contents of the existing note. - combine_notes_overwrite() replaces the existing note with the new note. - combine_notes_ignore() keeps the existing note, and ignores the new note. A combine_notes function can be passed to init_notes() to choose a default combine_notes function for that notes tree. If NULL is given, the notes tree falls back to combine_notes_concatenate() as the ultimate default. A combine_notes function can also be passed directly to add_note(), to control the notes combining behaviour for a note addition in particular. If NULL is passed, the combine_notes function registered for the given notes tree is used. Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
