Stefan Sperling 1fee9f40 2021-04-13T08:28:24 fix 3-way merge of files which lack a final \n problem found by jrick ok millert
Stefan Sperling bc62ede8 2021-02-26T17:31:35 use Myers diff instead of Patience diff when merging files with diff3 Myers diff tends to divide files into smaller diff chunks, while Patience diff attemps to maximize the size of diff chunks. Smaller diffs chunks generally result in a more managable presentation of merge conflicts.
Stefan Sperling 56b63ca4 2021-01-22T11:04:47 make fclose(3) failure checks consistent; check 'fclose() == EOF' everywhere ok millert, naddy
Stefan Sperling 16aeacf7 2020-11-26T12:54:19 use size_t for loop indices to avoid signedness warnings; from emaste@freebsd
Stefan Sperling 1cb46f00 2020-11-21T15:34:19 consistently label removed files as "/dev/null" in diff headers
Stefan Sperling 64453f7e 2020-11-21T13:35:00 handle binary files in got/tog diff commands; add -a options to force text
Stefan Sperling fe621944 2020-11-10T22:54:37 merge new diff implementation from the git.gameoftrees.org diff.git repository This new diff implementation was started by Neels Hofmeyr during the u2k20 hackathon and now replaces diffreg.c code lifted from the OpenBSD base system. The integration of this code into Got was done by me. Got now uses the patience diff algorithm by default. The diff.git repository will remain the primary repository for the diff code, which already compiles and runs on other operating systems such as Linux. Any fixes and improvements for files inherited from the diff.git repository should be written against that repository and synced to got.git afterwards.
Stefan Sperling 21c17f12 2020-06-26T07:09:35 fix merging with files that do not contain a newline character; ok millert@
Stefan Sperling bb63914a 2020-02-17T21:57:56 make tmp dir location a compile-time setting and change gotweb's tmp dir We are not sure whether a gotweb package can own /var/www/tmp on OpenBSD. Moving gotweb's tmp dir to /var/www/got/tmp sidesteps that issue.

Stefan Sperling 68bda3b1 2019-10-09T08:20:05 diff3.c: check for unlink errors and unlink dp13 and dp23 again

Steven McDonald 6dea73df 2019-09-22T22:47:16 Replace fgetln() with getline() getline() is, per the latter's OpenBSD man page, safer and more portable than fgetln().
