Introduce die_errno() that appends strerror(errno) to die()

2009-06-27T18:14:53Z

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.

Increase the size of the die/warning buffer to avoid truncation

2009-03-24T23:58:20Z

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 Signed-off-by: Junio C Hamano

usage.c: remove unused functions

This removes three functions that are not used anywhere. Signed-off-by: Nanako Shiraishi Acked-by: Lars Hjemli Signed-off-by: Shawn O. Pearce

print warning/error/fatal messages in one shot

Not doing so is likely to create a messed up display when sent over the sideband protocol. Signed-off-by: Nicolas Pitre Signed-off-by: Junio C Hamano

Rename warn() to warning() to fix symbol conflicts on BSD and Mac OS

2007-03-31T08:11:11Z

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" Cc: "Randal L. Schwartz" Signed-off-by: Junio C Hamano

Introduce a global level warn() function.

2006-12-22T06:59:34Z

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.

Customizable error handlers

2006-06-24T07:12:52Z

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 Signed-off-by: Junio C Hamano

Clean up compatibility definitions.

2005-12-05T23:50:29Z

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.
