2010-01-05run-command: convert simple callsites to use_shellLibravatar Jeff King1-3/+3
Now that we have the use_shell feature, these callsites can all be converted with small changes. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-08-10Merge branch 'js/run-command-updates'Libravatar Junio C Hamano1-4/+0
* js/run-command-updates: api-run-command.txt: describe error behavior of run_command functions run-command.c: squelch a "use before assignment" warning receive-pack: remove unnecessary run_status report run_command: report failure to execute the program, but optionally don't run_command: encode deadly signal number in the return value run_command: report system call errors instead of returning error codes run_command: return exit code as positive value MinGW: simplify waitpid() emulation macros
2009-07-06Merge branch 'tr/die_errno'Libravatar Junio C Hamano1-1/+1
* tr/die_errno: Use die_errno() instead of die() when checking syscalls Convert existing die(..., strerror(errno)) to die_errno() die_errno(): double % in strerror() output just in case Introduce die_errno() that appends strerror(errno) to die()
2009-07-05run_command: return exit code as positive valueLibravatar Johannes Sixt1-4/+0
As a general guideline, functions in git's code return zero to indicate success and negative values to indicate failure. The run_command family of functions followed this guideline. But there are actually two different kinds of failure: - failures of system calls; - non-zero exit code of the program that was run. Usually, a non-zero exit code of the program is a failure and means a failure to the caller. Except that sometimes it does not. For example, the exit code of merge programs (e.g. external merge drivers) conveys information about how the merge failed, and not all exit calls are actually failures. Furthermore, the return value of run_command is sometimes used as exit code by the caller. This change arranges that the exit code of the program is returned as a positive value, which can now be regarded as the "result" of the function. System call failures continue to be reported as negative values. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-07-01Remove filename from conflict markersLibravatar Martin Renold1-4/+4
Put filenames into the conflict markers only when they are different. Otherwise they are redundant information clutter. Print the filename explicitely when warning about a binary conflict. Signed-off-by: Martin Renold <martinxyz@gmx.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-06-27Use die_errno() instead of die() when checking syscallsLibravatar Thomas Rast1-1/+1
Lots of die() calls did not actually report the kind of error, which can leave the user confused as to the real problem. Use die_errno() where we check a system/library call that sets errno on failure, or one of the following that wrap such calls: Function Passes on error from -------- -------------------- odb_pack_keep open read_ancestry fopen read_in_full xread strbuf_read xread strbuf_read_file open or strbuf_read_file strbuf_readlink readlink write_in_full xwrite Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-06-20Merge branch 'sb/maint-1.6.0-add-config-fix'Libravatar Junio C Hamano1-4/+4
* sb/maint-1.6.0-add-config-fix: add: allow configurations to be overriden by command line use xstrdup, not strdup in ll-merge.c Conflicts: builtin-add.c
2009-06-14use xstrdup, not strdup in ll-merge.cLibravatar Jim Meyering1-4/+4
Otherwise, a fluky allocation failure would cause merge configuration settings to be silently ignored. Signed-off-by: Jim Meyering <meyering@redhat.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-06-09Simplify some instances of run_command() by using run_command_v_opt().Libravatar Johannes Sixt1-9/+2

2009-04-29replace direct calls to unlink(2) with unlink_or_warnLibravatar Alex Riesen1-1/+1
This helps to notice when something's going wrong, especially on systems which lock open files. I used the following criteria when selecting the code for replacement: - it was already printing a warning for the unlink failures - it is in a function which already printing something or is called from such a function - it is in a static function, returning void and the function is only called from a builtin main function (cmd_) - it is in a function which handles emergency exit (signal handlers) - it is in a function which is obvously cleaning up the lockfiles Signed-off-by: Alex Riesen <raa.lkml@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-08-30git-merge-recursive: learn to honor merge.conflictstyleLibravatar Junio C Hamano1-5/+13
This teaches the low-level ll_xdl_merge() routine to honor merge.conflictstyle configuration variable, so that merge-recursive strategy can show the conflicts in the style of user's choice. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-05-14Provide git_config with a callback-data parameterLibravatar Johannes Schindelin1-2/+2
git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

2008-02-18merge-recursive: split low-level merge functions out.Libravatar Junio C Hamano1-0/+379
This moves low-level merge functions out of merge-recursive.c and places them in a new separate file, ll-merge.c Signed-off-by: Junio C Hamano <gitster@pobox.com>
