Thanks for your comments. Looking forward to seeing some more input.
- contrib/buffer_capture_cmp/README
- 'contains' seems duplicate in the first paragraph. - The second paragraph says that 'This script can use the node number of the master node available as the first argument of the script when it is run within the test suite.' But test.sh seems not giving such a parameter.
Yeah right... This was a rest of some previous hacking on this feature. Paragraph was rather unclear so I rewrote it, mentioning that the custom script can use PGPORT to connect to the node where tests can be run.
- contrib/buffer_capture_cmp/Makefile
"make check" does nothing when BUFFER_CAPTURE is not defined, as described in itself. But I trapped by that after build the server by 'make CFLAGS="-DBUFFER_CAPTURE"':( It would be better that 'make check' without defining it prints some message.
Sure, I added such a message in the makefile.
- buffer_capture_cmp.c
This source generates void executable when BUFFER_CAPTURE is not defined. The restriction seems to be put only to use BUFFER_CAPTURE_FILE in bufcapt.h. If so, changing the parameter of the executable as described in the following comment for main() would blow off the necessity for the restriction.
Done. The compilation of this utility is now independent on BUFFER_CAPTURE. At the same time I made test.sh a bit smarter to have it grab the value of BUFFER_CAPTURE_FILE directly from bufcapt.h.
- buffer_capture_cmp.c/main()
The parameters for this command are the parent directories for each capture file. This is a bit inconvenient for separate use. For example, when I want to gather the capture files from multiple servers then compare them, I should unwillingly make their own directories for each capture file. If no particular reason exists for the design, I suppose it would be more convenient that the parameters are the names of the capture files themselves.
Fixed. I changed back the utility to directly file names instead of data folders as arguments.
Updated patches addressing those comments are attached.
