2013-11-08The "file types" we have are actually combinations of types andGuy Harris1-1/+1
subtypes, e.g. Network Monitor version 1 and Network Monitor version 2 are separate "file types", even though they both come from Network Monitor. Rename various functions, #defines, and variables appropriately. svn path=/trunk/; revision=53166
2013-06-18Slight stylistic cleanup - most routines, when defined, have no spaceGuy Harris1-1/+1
between the routine name and the opening parenthesis, so remove it from the definition of the seek-read routine. svn path=/trunk/; revision=50026
2013-06-17Merge "read record header" and "read packet data" routines into a singleGuy Harris1-3/+6
routine, used both by read and seek-read routines. svn path=/trunk/; revision=49988
2013-06-16Have the seek-read routines take a Buffer rather than a guint8 pointerGuy Harris1-18/+17
as the "where to put the packet data" argument. This lets more of the libwiretap code be common between the read and seek-read code paths, and also allows for more flexibility in the "fill in the data" path - we can expand the buffer as needed in both cases. svn path=/trunk/; revision=49949
2013-05-16Fill in the presence flags in parse_cosine_rec_hdr(), so it's done atGuy Harris1-31/+29
the same point at which the rest of the wtap_pkthdr is filled in (so it's done in seek-read routines). parse_cosine_hex_dump()'s return value is used as the return value of read routines, so it should be Boolean. Make it so (and have it stuff the actual length of packet data read into a wtap_pkthdr, which also ensure that this is done in seek-read routines). svn path=/trunk/; revision=49352
2012-12-27Errors take precedence over EOF; use file_error() after operations thatGuy Harris1-19/+10
return an "EOF or error" indication - an EOF without an error will return 0. In iseries_seek_next_packet(), return an error code of WTAP_ERR_BAD_FILE and an appropriate error message if we don't find a packet header within the next ISERIES_MAX_TRACE_LEN lines, don't just return -1 and leave the error information unchanged. Setting an argument variable before returning has no effect, so don't do it (so that we don't leave the mistaken impression that it *is* doing something). Clean up indentation. svn path=/trunk/; revision=46819
2012-12-27Do not call wtap_file_read_unknown_bytes() orGuy Harris1-20/+15
wtap_file_read_expected_bytes() from an open routine - open routines are supposed to return -1 on error, 0 if the file doesn't appear to be a file of the specified type, or 1 if the file does appear to be a file of the specified type, but those macros will cause the caller to return FALSE on errors (so that, even if there's an I/O error, it reports "the file isn't a file of the specified type" rather than "we got an error trying to read the file"). When doing reads in an open routine before we've concluded that the file is probably of the right type, return 0, rather than -1, if we get WTAP_ERR_SHORT_READ - if we don't have enough data to check whether a file is of a given type, we should keep trying other types, not give up. For reads done *after* we've concluded the file is probably of the right type, if a read doesn't return the number of bytes we asked for, but returns an error of 0, return WTAP_ERR_SHORT_READ - the file is apparently cut short. For NetMon and NetXRay/Windows Sniffer files, use a #define for the magic number size, and use that for both magic numbers. svn path=/trunk/; revision=46803

2012-05-04file_seek() used to be a wrapper around fseek() or gzseek(), both ofGuy Harris1-2/+0
which could use lseek() and were thus expensive due to system call overhead. To avoid making a system call for every packet on a sequential read, we maintained a data_offset field in the wtap structure for sequential reads. It's now a routine that just returns information from the FILE_T data structure, so it's cheap. Use it, rather than maintaining the data_offset field. Readers for some file formats need to maintain file offset themselves; have them do so in their private data structures. svn path=/trunk/; revision=42423

svn path=/trunk/; revision=41627
2012-02-25Add a presence flag field to the packet information structure filled inGuy Harris1-0/+1
by Wiretap, to indicate whether certain fields in that structure actually have data in them. Use the "time stamp present" flag to omit showing time stamp information for packets (and "packets") that don't have time stamps; don't bother working very hard to "fake" a time stamp for data files. Use the "interface ID present" flag to omit the interface ID for packets that don't have an interface ID. We don't use the "captured length, separate from packet length, present" flag to omit the captured length; that flag might be present but equal to the packet length, and if you want to know if a packet was cut short by a snapshot length, comparing the values would be the way to do that. More work is needed to have wiretap/pcapng.c properly report the flags, e.g. reporting no time stamp being present for a Simple Packet Block. svn path=/trunk/; revision=41185
2011-12-13Rename WTAP_ERR_BAD_RECORD to WTAP_ERR_BAD_FILE; it really reports anyGuy Harris1-3/+3
form of corruption/bogosity in a file, including in a file header as well as in records in the file. Change the error message wtap_strerror() returns for it to reflect that. Use it for some file header problems for which it wasn't already being used - WTAP_ERR_UNSUPPORTED shouldn't be used for that, it should only be used for files that we have no reason to believe are invalid but that have a version number we don't know about or some other non-link-layer-encapsulation-type value we don't know about. svn path=/trunk/; revision=40175
2011-04-21Add a new WTAP_ERR_DECOMPRESS error, and use that for errors discoveredGuy Harris1-14/+18
by the gunzipping code. Have it also supply a err_info string, and report it. Have file_error() supply an err_info string. Put "the file" - or, for WTAP_ERR_DECOMPRESS, "the compressed file", to suggest a decompression error - into the rawshark and tshark errors, along the lines of what other programs print. Fix a case in the Netscaler code where we weren't fetching the error code on a read failure. svn path=/trunk/; revision=36748

2005-08-24EVERYTHING IN THE BUILDBOT IS GOING TO BE RED!!! Sorry! Ulf Lamping1-2/+2
I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ... What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere. As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon. Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way... As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number... svn path=/trunk/; revision=15520

they have LF at the end of the line on UN*X and CR/LF on Windows; hopefully this means that if a CR/LF version is checked in on Windows, the CRs will be stripped so that they show up only when checked out on Windows, not on UN*X. svn path=/trunk/; revision=11400
2004-03-03Have "wtap_read()" set "wth->phdr.pkt_encap" to "wth->file_encap",Guy Harris1-2/+1
rather than requiring individual capture file type handlers to do it (unless they're doing per-packet encapsulation, in which case we check to make sure they didn't *leave* it as WTAP_ENCAP_PER_PACKET). svn path=/trunk/; revision=10290

2004-01-25Have the Wiretap open, read, and seek-and-read routines return, inGuy Harris1-14/+24
addition to an error code, an error info string, for WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and WTAP_ERR_BAD_RECORD errors. Replace the error messages logged with "g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed strings returned as the error info string, and change the callers of those routines to, for those errors, put the info string into the printed message or alert box for the error. Add messages for cases where those errors were returned without printing an additional message. Nobody uses the error code from "cf_read()" - "cf_read()" puts up the alert box itself for failures; get rid of the error code, so it just returns a success/failure indication. Rename "file_read_error_message()" to "cf_read_error_message()", as it handles read errors from Wiretap, and have it take an error info string as an argument. (That handles a lot of the work of putting the info string into the error message.) Make some variables in "ascend-grammar.y" static. Check the return value of "erf_read_header()" in "erf_seek_read()". Get rid of an unused #define in "i4btrace.c". svn path=/trunk/; revision=9852
