2009-06-27die_errno(): double % in strerror() output just in caseLibravatar Junio C Hamano1-2/+18
[tr: handle border case where % is placed at end of buffer] Signed-off-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-06-27Introduce die_errno() that appends strerror(errno) to die()Libravatar Thomas Rast1-0/+12
There are many calls to die() that do, or should, report strerror(errno) to indicate how the syscall they guard failed. Introduce a small helper function for this case. Note: - POSIX says vsnprintf can modify errno in some unlikely cases, so we have to use errno early. - We take some care to pass the original format to die_routine(), in case someone wants to call die_errno() with custom format characters.

2009-03-24Increase the size of the die/warning buffer to avoid truncationLibravatar Shawn O. Pearce1-1/+1
Long messages like those from lockfile.c when a lock can't be obtained truncate with only 256 bytes in the message buffer. Bump it to 1024 to give more space for these longer cases. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-09-29usage.c: remove unused functionsLibravatar Nanako Shiraishi1-16/+0
This removes three functions that are not used anywhere. Signed-off-by: Nanako Shiraishi <nanako3@lavabit.com> Acked-by: Lars Hjemli <hjemli@gmail.com> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-11-09print warning/error/fatal messages in one shotLibravatar Nicolas Pitre1-3/+3
Not doing so is likely to create a messed up display when sent over the sideband protocol. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-03-31Rename warn() to warning() to fix symbol conflicts on BSD and Mac OSLibravatar Theodore Ts'o1-1/+1
This fixes a problem reported by Randal Schwartz: >I finally tracked down all the (albeit inconsequential) errors I was getting >on both OpenBSD and OSX. It's the warn() function in usage.c. There's >warn(3) in BSD-style distros. It'd take a "great rename" to change it, but if >someone with better C skills than I have could do that, my linker and I would >appreciate it. It was annoying to me, too, when I was doing some mergetool testing on Mac OS X, so here's a fix. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: "Randal L.

2006-12-21Introduce a global level warn() function.Libravatar Shawn O. Pearce1-0/+19
Like the existing error() function the new warn() function can be used to describe a situation that probably should not be occuring, but which the user (and Git) can continue to work around without running into too many problems. An example situation is a bad commit SHA1 found in a reflog. Attempting to read this record out of the reflog isn't really an error as we have skipped over it in the past. Signed-off-by: Shawn O.

2006-06-24Customizable error handlersLibravatar Petr Baudis1-4/+42
This patch makes the usage(), die() and error() handlers customizable. Nothing in the git code itself uses that but many other libgit users (like Git.pm) will. This is implemented using the mutator functions primarily because you cannot directly modifying global variables of libgit from a program that dlopen()ed it, apparently. But having functions for that is a better API anyway. Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-12-05Clean up compatibility definitions.Libravatar Junio C Hamano1-1/+1
This attempts to clean up the way various compatibility functions are defined and used. - A new header file, git-compat-util.h, is introduced. This looks at various NO_XXX and does necessary function name replacements, equivalent of -Dstrcasestr=gitstrcasestr in the Makefile. - Those function name replacements are removed from the Makefile. - Common features such as usage(), die(), xmalloc() are moved from cache.h to git-compat-util.h; cache.h includes git-compat-util.h itself.

2005-10-01[PATCH] Better error reporting for "git status"Libravatar Linus Torvalds1-2/+2
Instead of "git status" ignoring (and hiding) potential errors from the "git-update-index" call, make it exit if it fails, and show the error. In order to do this, use the "-q" flag (to ignore not-up-to-date files) and add a new "--unmerged" flag that allows unmerged entries in the index without any errors. This also avoids marking the index "changed" if an entry isn't actually modified, and makes sure that we exit with an understandable error message if the index is corrupt or unreadable. "read_cache()" no longer returns an error for the caller to check. Finally, make die() and usage() exit with recognizable error codes, if we ever want to check the failure reason in scripts.

2005-05-22Include file cleanups..Libravatar Linus Torvalds1-1/+0
Add <limits.h> to the include files handled by "cache.h", and remove extraneous #include directives from various .c files. The rule is that "cache.h" gets all the basic stuff, so that we'll have as few system dependencies as possible.
2005-04-18Split up read-cache.c into more logical clumps.Libravatar Linus Torvalds1-0/+40
Do the usage and error reporting in "usage.c", and the sha1 file accesses in "sha1_file.c". Small, nice, easily separated parts. Good.
