2015-11-18Revert: Free cf->edt before free cf->epan when redissecting.Gerald Combs1-4/+0
Instead of freeing cf->edt before clearing the packet list, add an extra check to MainWindow::setMenusForSelectedTreeRow. Semi-blind attempt at fixing bug 11719. This reverts commit 8c211d51ef66b64c708f7ad079e7e7e913ac9f14. This reverts commit da71ccbf778cca5d9c48e010597570a40fd190c0.

2015-11-18epan: Check for valid cf->edt before free.Stig Bjørlykke1-2/+4
Added a check for a valid cf->edt before calling epan_dissect_free(), as this will give an unintended assert. This is related to da71ccbf778cca5d9c48e010597570a40fd190c0.

2015-11-13epan: Free cf->edt before free cf->epan when redissecting.Stig Bjørlykke1-0/+2
This because cf->edt->pi is pointing to data allocated in wmem_file_scope and epan_free() will free all data in wmem_file_scope. In Qt packet_list_clear() we check and use cf->edt, which will give a heap-use-after-free error.

Refactor the file merging code by removing the duplicate logic from mergecap.c and file.c's cf_merge_files(), into a new merge_files() function in merge.c. Also the following user-visible changes: * Removed the '-T' encap type option from mergecap, as it's illogical for mergecap and would complicate common merge code. * Input files with IDBs of different name, speed, tsprecision, etc., will produce an output PCAPNG file with separate IDBs, even if their encap types are the same. * Added a '-I' IDB merge mode option for mergecap, to control how IDBs are merged. * Changed Wireshark's drag-and-drop merging to use PCAPNG instead of PCAP.

Have the count in a cfile_t structure always reflect the actual number of packets that have been read from the file, rather than, when doing a non-update-list-of-packets-in-real-time capture, falsely increasing the count in the cfile_t to reflect the number of packets captured but not yet read. Have the status bar base its captured-packet count on the count in the capture_session structure, and base the "sorry, no packets were captured" message on the count in the capture_session structure, as we're no longer using the count in the cfile_t structure to count anything in the process of a non-update-list-of-packets-in-real-time capture. That way, we preserve the invariant that the "frames" member of a cfile_t will be non-null if the "count" member is non-zero, fixing bug 6217. It also means we can get rid of cf_set_packet_count(), as we only set the count in the capture-file-reading code.

2014-11-22Get rid of write_headers global variable.Guy Harris1-2/+2
Have write_psml_preamble() and write_csv_preamble() take a capture_file * as an argument, so they can print the column titles themselves, rather than having to defer it to the routine that prints packet data.

2014-10-20Fix support for writing out edited records.Guy Harris1-1/+45
Add a cf_set_frame_edited() routine to set the record header and data for a record; have it do all the non-GUI work, and have it set the file's "unsaved changes" flag. Have the GUI code just call that routine and then update the title bar to reflect the unsaved changes. While we're at it, unmark a no-longer-unused argument to save_record().

2014-10-07No need for WTAP_ERR_CANT_READ.Guy Harris1-18/+0
Unlike the standard I/O routines, the code we introduced that supports fast random seeking on gzipped files will always supply some specific error code for read errors, so we don't need WTAP_ERR_CANT_READ. Add WTAP_ERR_CANT_WRITE for writing, as we're still using the standard I/O routines for that. Set errno to WTAP_ERR_CANT_WRITE before calling fwrite() in wtap_dump_file_write(), so that it's used if fwrite() fails without setting errno.

2014-09-28Make the time stamp resolution per-packet.Guy Harris1-34/+0
Pcap-ng files don't have a per-file time stamp resolution, they have a per-interface time stamp resolution. Add new time stamp resolution types of "unknown" and "per-packet", add the time stamp resolution to struct wtap_pkthdr, have the libwiretap core initialize it to the per-file time stamp resolution, and have pcap-ng do the same thing with the resolution that it does with the packet encapsulation. Get rid of the TS_PREC_AUTO_XXX values; just have TS_PREC_AUTO, which means "use the packet's resolution to determine how many significant digits to display". Rename all the WTAP_FILE_TSPREC_XXX values to WTAP_TSPREC_XXX, as they're also used for per-packet values.

Rename simple_dialog_qt.{cpp,h} to simple_dialog.{cpp,h}. Make it a subclass of QMessageBox. Queue messages at startup similar to GTK+. Move the GTK+-specific simple_dialog declarations to gtk/simple_dialog.h. Don't yell at the user so much. Replace exclamation points with periods.

2014-08-02Rename buffer_ routines to ws_buffer_ to avoid name collisions.Guy Harris1-14/+14
In particular, epan/wslua/lrexlib.c has its own buffer_ routines, causing some linker warnings on some platforms, as reported in bug 10332. (Not to be backported to 1.12, as that would change the API and ABI of libwsutil and libwiretap. We should also make the buffer_ routines in epan/wslua/lrexlib.c static, which should also address this problem, but the name change avoids other potential namespace collisions.)
