2011-04-03sparse: Fix errors and silence warningsLibravatar Stephen Boyd1-1/+1
* load_file() returns a void pointer but is using 0 for the return value * builtin/receive-pack.c forgot to include builtin.h * packet_trace_prefix can be marked static * ll_merge takes a pointer for its last argument, not an int * crc32 expects a pointer as the second argument but Z_NULL is defined to be 0 (see 38f4d13 sparse fix: Using plain integer as NULL pointer, 2006-11-18 for more info) Signed-off-by: Stephen Boyd <bebarino@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-03-08add packet tracing debug codeLibravatar Jeff King1-1/+54
This shows a trace of all packets coming in or out of a given program. This can help with debugging object negotiation or other protocol issues. To keep the code changes simple, we operate at the lowest level, meaning we don't necessarily understand what's in the packets. The one exception is a packet starting with "PACK", which causes us to skip that packet and turn off tracing (since the gigantic pack data will not be interesting to read, at least not in the trace format). We show both written and read packets. In the local case, this may mean you will see packets twice (written by the sender and read by the receiver). However, for cases where the other end is remote, this allows you to see the full conversation. Packet tracing can be enabled with GIT_TRACE_PACKET=<foo>, where <foo> takes the same arguments as GIT_TRACE.

2009-10-30pkt-line: Make packet_read_line easier to debugLibravatar Shawn O. Pearce1-1/+1
When there is an error parsing the 4 byte length component we now display it as part of the die message, this may hint as to what data was misunderstood by the application. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-10-30pkt-line: Add strbuf based functionsLibravatar Shawn O. Pearce1-12/+72
These routines help to work with pkt-line values inside of a strbuf, permitting simple formatting of buffered network messages. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-06-27Convert existing die(..., strerror(errno)) to die_errno()Libravatar Thomas Rast1-2/+2
Change calls to die(..., strerror(errno)) to use the new die_errno(). In the process, also make slight style adjustments: at least state _something_ about the function that failed (instead of just printing the pathname), and put paths in single quotes.

2008-05-03Cleanup xread() loops to use read_in_full()Libravatar Heikki Orsila1-10/+5

2007-06-07War on whitespaceLibravatar Junio C Hamano1-1/+1
This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

2007-05-15Ensure return value from xread() is always stored into an ssize_tLibravatar Johan Herland1-2/+2
This patch fixes all calls to xread() where the return value is not stored into an ssize_t. The patch should not have any effect whatsoever, other than putting better/more appropriate type names on variables.

2006-12-18make git a bit less cryptic on fetch errorsLibravatar Nicolas Pitre1-1/+1
The remote server might not want to tell why it doesn't like us for security reasons, but let's make the client report such error in a bit less confusing way. The remote failure remains a mystery, but the local message might be a bit less so.

2006-06-21Merge branch 'ff/c99' into nextLibravatar Junio C Hamano1-2/+2
* ff/c99: Remove all void-pointer arithmetic.
2006-06-21upload-pack/fetch-pack: support side-band communicationLibravatar Junio C Hamano1-1/+3
This implements a protocol extension between fetch-pack and upload-pack to allow stderr stream from upload-pack (primarily used for the progress bar display) to be passed back. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-06-20Remove all void-pointer arithmetic.Libravatar Florian Forster1-2/+2
ANSI C99 doesn't allow void-pointer arithmetic. This patch fixes this in various ways. Usually the strategy that required the least changes was used. Signed-off-by: Florian Forster <octo@verplant.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-12-19xread/xwrite: do not worry about EINTR at calling sites.Libravatar Junio C Hamano1-8/+3
We had errno==EINTR check after read(2)/write(2) sprinkled all over the places, always doing continue. Consolidate them into xread()/xwrite() wrapper routines. Credits for suggestion goes to HPA -- bugs are mine. Signed-off-by: Junio C Hamano <junkio@cox.net>
