Oded Shimon acaa8374d0 Fix & optimization for unzip_match 
read_fdhist() cannot be called after write_1g() is called, in case that write() caused a switch to !TMP_OUTBUF, moving the read pointer.
read_fdhist() should only be called immediately after seekto_fdhist()

In this case, only one call to read_fdhist() was enough, before the loop, as subsuequent calls only gave repeats of the same data.

Con Kolivas a0fe1a8c8e Merge branch 'master' into liblrzip 
Conflicts:
	runzip.c
	stream.h
 2011-09-15 08:31:00 +10:00
Con Kolivas e1f2138060 Make sure to read to the end of all streams when closing down an rzip stream. 
This would have made lrzip unable to decompress some rare archives if they ended up stream 0.

Con Kolivas a39b57a1e7 Add lots more debugging in maxverbose mode about where data is being written. 2011-09-15 08:26:07 +10:00
discomfitor 949c6d7a97 another semi-clusterfuck commit: *new logging macros *allow compression to and from any FILE, not just stdin/stdout *update main.c to work with the above 2011-08-17 20:59:41 +10:00
discomfitor 6dd20d735b giant clusterfuck commit: *add and use alloca/strdupa in some spots *implement return values on almost every function *free() is now a macro which also nulls the freed pointer *when in 'library mode', fatal_exit() will not be called *fatal()/failure() are now macros which add line number and file for logging *all occurrences of fatal/failure in files other than main.c are now wrapped to use a logging callback (if specified) and then return *functions now clean up resources on returning with an error 2011-08-17 20:59:40 +10:00
discomfitor cbff8faef7 move liblrzip.h contents to lrzip_private.h global variables----- 2011-08-17 20:59:40 +10:00

Con Kolivas f7a1c14e28 Put warning about possibly wrong password at appropriate place in stream.c 
Use char to be consistent in open_stream_in.
Fail to failure() instead of fatal() should open_stream_in fail.
