line-range: plug leaking find functions

2024-06-11T20:15:08Z

In `parse_range_funcname()` we may end up allocating a "find function", but never free it. Fix this. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

treewide: remove unnecessary includes in source files

2023-12-26T20:04:31Z

Each of these were checked with gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE} to ensure that removing the direct inclusion of the header actually resulted in that header no longer being included at all (i.e. that no other header pulled it in transitively). ...except for a few cases where we verified that although the header was brought in transitively, nothing from it was directly used in that source file. These cases were: * builtin/credential-cache.c * builtin/pull.c * builtin/send-pack.c Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

line-range: fix infinite loop bug with '$' regex

2022-12-20T01:00:43Z

When the -L argument to "git log" is passed the zero-width regular expression "$" (as in "-L :$:line-range.c"), this results in an infinite loop in find_funcname_matching_regexp(). Modify find_funcname_matching_regexp to correctly match the entire line instead of the zero-width match at eol and update the loop condition to prevent an infinite loop in the event of other undiscovered corner cases. The primary change is that we pre-decrement the beginning-of-line marker ('bol') before comparing it to '\n'. In the case of '$', where we match the '\n' at the end of the line and start the loop with bol == eol, this ensures that bol will find the beginning of the line on which the match occurred.

use CALLOC_ARRAY

2021-03-14T00:00:09Z

Add and apply a semantic patch for converting code that open-codes CALLOC_ARRAY to use it instead. It shortens the code and infers the element size automatically. Signed-off-by: René Scharfe Signed-off-by: Junio C Hamano

blame: prevent error if range ends past end of file

2018-06-15T17:29:13Z

If the -L option is used to specify a line range in git blame, and the end of the range is past the end of the file, git will fail with a fatal error. This commit prevents such behavior - instead we display the blame for existing lines within the specified range. Tests are amended accordingly. This commit also fixes two corner cases. Blaming -L n,-(n+1) now blames the first n lines of a file rather than from n to the end of the file. Blaming -L ,-n will be treated as -L 1,-n and blame the first line of the file, rather than blaming the whole file. Signed-off-by: Isabella Stephens Signed-off-by: Junio C Hamano

use SWAP macro

2017-01-30T22:17:00Z

Apply the semantic patch swap.cocci to convert hand-rolled swaps to use the macro SWAP. The resulting code is shorter and easier to read, the object code is effectively unchanged. The patch for object.c had to be hand-edited in order to preserve the comment before the change; Coccinelle tried to eat it for some reason. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

line-range: reject -L line numbers less than 1

2013-08-06T21:48:55Z

Since inception, git-blame -L has been documented as accepting 1-based line numbers. When handed a line number less than 1, -L's behavior is undocumented and undefined; it's also nonsensical and should be diagnosed as an error. Do so. Signed-off-by: Eric Sunshine Signed-off-by: Junio C Hamano

line-range: teach -L^:RE to search from start of file

2013-08-06T21:48:02Z

The -L:RE option of blame/log searches from the end of the previous -L range, if any. Add new notation -L^:RE to override this behavior and search from start of file. Signed-off-by: Eric Sunshine Signed-off-by: Junio C Hamano
