* tests: disable fsync everywhereEric Wong2021-10-291-2/+15
| | | | | | | | | | | | | | | | | | | | The "GIT_TEST_FSYNC" environment variable now exists for disabling fsync() even on packfiles and other "critical" data. Running "make test -j8 NO_SVN_TESTS=1" on a noisy 8-core system on an HDD, test runtime drops from ~4 minutes down to ~3 minutes. Using "GIT_TEST_FSYNC=1" re-enables fsync() for comparison purposes. SVN interopability tests are minimally affected since SVN will still use fsync in various places. This will also be useful for 3rd-party tools which create throwaway git repositories of temporary data, but remains undocumented for end users.

* perl: check for perl warnings while running testsJeff King2020-10-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We set "use warnings" in most of our perl code to catch problems. But as the name implies, warnings just emit a message to stderr and don't otherwise affect the program. So our tests are quite likely to miss that warnings are being spewed, as most of them do not look at stderr. We could ask perl to make all warnings fatal, but this is likely annoying for non-developers, who would rather have a running program with a warning than something that refuses to work at all. So instead, let's teach the perl code to respect an environment variable (GIT_PERL_FATAL_WARNINGS) to increase the severity of the warnings. This can be set for day-to-day running if people want to be really pedantic, but the primary use is to trigger it within the test suite. We could also trigger that for every test run, but likewise even the tests failing may be annoying to distro builders, etc (just as -Werror would be for compiling C code). So we'll tie it to a special test-mode variable (GIT_TEST_PERL_FATAL_WARNINGS) that can be set in the environment or as a Makefile knob, and we'll automatically turn the knob when DEVELOPER=1 is set. That should give developers and CI the more careful view without disrupting normal users or packagers. Note that the mapping from the GIT_TEST_* form to the GIT_* form in test-lib.sh is necessary even if they had the same name: the perl scripts need it to be normalized to a perl truth value, and we also have to make sure it's exported (we might have gotten it from the environment, but we might also have gotten it from GIT-BUILD-OPTIONS directly).

* perl: make SVN code hash independentbrian m. carlson2020-06-221-35/+38
| | | | | | | | | | | | | | | | | There are several places throughout git-svn that use various hard-coded constants. For matching object IDs, use the $oid variable. Compute the record size we use for our revision storage based on the object ID. When parsing the revision map format, use a wildcard in the pack format since we know that the data we're parsing is always exactly the record size. This lets us continue to use a constant for the pack format. Finally, update several comments to reflect the fact that an object ID may be of one of multiple sizes.

* perl: create and switch variables for hash constantsbrian m. carlson2020-06-221-5/+5
| | | | | | | | | | | | | | | | git-svn has several variables for SHA-1 constants, including short hash values and full length hash values. Since these are no longer SHA-1 specific, let's start them with "oid" instead of "sha1". Add a constant, oid_length, which is the length of the hash algorithm in use in hex. We use the hex version because overwhelmingly that's what's used by git-svn. We don't currently set oid_length based on the repository algorithm, but we will in a future commit.

* git-svn: trim leading and trailing whitespaces in author nameTobias Klauser2019-09-281-0/+4
| | | | | | | | | | | | | | | | | | | | In some cases, the svn author names might contain leading or trailing whitespaces, leading to messages such as: Author: user1 not defined in authors.txt (the trailing newline leads to the line break). The user "user1" is defined in authors.txt though, e.g. user1 = User <user1@example.com> Fix this by trimming the author name retreived from svn before using it in check_author.

* git-svn: allow empty email-address using authors-prog and authors-fileAndreas Heiduk2018-04-051-7/+6
| | | | | | | | | | | | | | | | | | | | The email address in --authors-file and --authors-prog can be empty but git-svn translated it into a fictional email address in the form jondoe <jondoe@6aafaa21e0fb4338a68ab372a049893d> containing the SVN repository UUID. Now git-svn behaves like git-commit: If the email is *explicitly* set to the empty string using '<>', the commit does not contain an email address, only the name: jondoe <> Allowing to remove the email address *intentionally* prevents automatic systems from sending emails to those fictional addresses and avoids cluttering the log output with unnecessary stuff.

* perl: call timegm and timelocal with 4-digit yearbw/perl-timegm-timelocal-fixBernhard M. Wiedemann2018-02-231-1/+1
| | | | | | | | | | | | | | | | | | | | | Amazingly, timegm(gmtime(0)) is only 0 before 2020 because perl's timegm deviates from GNU timegm(3) in how it handles years. man Time::Local says Whenever possible, use an absolute four digit year instead. with a detailed explanation about ambiguity of 2-digit years above that. Even though this ambiguity is error-prone with >50% of users getting it wrong, it has been like this for 20+ years, so we just use 4-digit years everywhere to be on the safe side. We add some extra logic to cvsimport because it allows 2-digit year input and interpreting an 18 as 1918 can be avoided easily and safely. Signed-off-by: Bernhard M.

| * git-svn: do not reuse caches memoized for a different architectureGavin Lambert2016-10-271-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reusing cached data speeds up git-svn by quite a fair bit. However, if the YAML module is unavailable, the caches are written to disk in an architecture-dependent manner. That leads to problems when upgrading, say, from 32-bit to 64-bit Git for Windows. Let's just try to read those caches back if we detect the absence of the YAML module and the presence of the file, and delete the file if it could not be read back correctly. Note that the only way to catch the error when the memoized cache could not be read back is to put the call inside an `eval { ... }` block because it would die otherwise; the `eval` block should also return `1` in case of success explicitly since the function reading back the cached data does not return an appropriate value to test for success.

* git-svn: improve rebase/mkdirs performanceDair Grant2015-11-101-8/+76
| | | | | | | | | | | | | | | | | | | | | | Processing empty_dir directives becomes extremely slow for svn repositories with a large enough history. This is due to using a single hash to store the list of empty directories, with the expensive step being purging items from that hash using grep+delete. Storing directories in a hash of hashes improves the performance of this purge step and removes a potentially lengthy delay after every rebase/mkdirs command. The svn repository with this behaviour has 110K commits with unhandled.log containing 170K empty_dir directives. This takes 10 minutes to process when using a single hash, vs 3 seconds with a hash of hashes. Signed-off-by: Dair Grant <dair@feralinteractive.com> Signed-off-by: Eric Wong <normalperson@yhbt.net>

* | git-svn: lazy load some modulesEric Wong2015-02-261-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | We can delay loading some modules until we need them for uncommon code paths. For example, persistent memoization is not often needed, so we can avoid loading the modules for it until we encounter svn::mergeinfo during fetch.

| | | | | | | | | | | | | | | | | | | | | | | | | | This memoization appears unneeded as the check_cherry_pick2 cache is in front of it does enough. With this change applied, importing from local svn+ssh and http copies of the R repo[1] takes only 2:00 (2 hours) on my system and the git-svn process never uses more than 60MB RSS on my x86-64 GNU/Linux system[2]. This 60M measurement is only for the git-svn Perl process itself and does not include memory used by git subprocesses accessing large packs (subprocess memory usage _is_ measured by my time(1) tool). Before this change, an import took longer (2:20) on svn+ssh:// but git-svn used around 240MB during the imports. Worse yet, git-svn ballooned to over 400M when writing out the cache to the filesystem. I also tried removing memoization for `has_no_changes', too, but a local copy of the R repository(*) was not close to finishing within 10 hours on my system.

| | | | | | | | | | | | | | | | | | | | | | In a Subversion repository where many feature branches are merged into a trunk, the svn:mergeinfo property can grow very large. This severely slows down git-svn's make_log_entry() because it is checking all mergeinfo entries every time the property changes. In most cases, the additions to svn:mergeinfo since the last commit are pretty small, and there is nothing to gain by checking merges that were already checked for the last commit in the branch. Add a mergeinfo_changes() function which computes the set of interesting changes to svn:mergeinfo since the last commit. Filter out merged branches whose ranges haven't changed, and remove a common prefix of ranges from other merged branches. This speeds up "git svn fetch" by several orders of magnitude on a large repository where thousands of feature branches have been merged.

| * git-svn: canonicalize newly-minted URLsMichael G. Schwern2012-08-021-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Go through all the spots that use the new add_path_to_url() to make a new URL and canonicalize them. * copyfrom_path has to be canonicalized else find_parent_branch will get confused * due to the `canonicalize_url($full_url) ne $full_url)` line of logic in gs_do_switch(), $full_url is left alone until after. At this point SVN 1.7 passes except for 3 tests in t9100-git-svn-basic.sh that look like an SVN bug to do with symlinks. [ew: commit title] Signed-off-by: Eric Wong <normalperson@yhbt.net>
| * git-svn: introduce add_path_to_url functionMichael G. Schwern2012-08-021-18/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the ad-hoc versions. This is mostly to normalize the process and ensure the URLs produced don't have double slashes or anything. Also provides a place to fix the corner case where a file path contains a percent sign. [ew: commit title] Signed-off-by: Eric Wong <normalperson@yhbt.net>
| * git-svn: replace URL escapes with canonicalizationMichael G. Schwern2012-08-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old hand-rolled URL escape functions were inferior to canonicalization functions. Continuing to move towards getting everything canonicalizing the same way. * Git::SVN->init_remote_config and Git::SVN::Ra->minimize_url both have to canonicalize the same way else init_remote_config will incorrectly think they're different URLs causing t9107-git-svn-migrate.sh to fail.

| * git-svn: attempt to mimic SVN 1.7 URL canonicalizationMichael G. Schwern2012-08-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, our URL canonicalization didn't do much of anything. Now it actually escapes and collapses slashes. This is mostly a cut & paste of escape_url from git-svn. This is closer to how SVN 1.7's canonicalization behaves. Doing it with 1.6 lets us chase down some problems caused by more effective canonicalization without having to deal with all the other 1.7 issues on top of that. * Remote URLs have to be canonicalized otherwise Git::SVN->find_existing_remote will think they're different. * The SVN remote is now written to the git config canonicalized. That should be ok. Adjust a test to account for that. [ew: commit title] Signed-off-by: Eric Wong <normalperson@yhbt.net>
| * Git::SVN{,::Ra}: canonicalize earlierMichael G. Schwern2012-08-021-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This canonicalizes paths and urls as early as possible so we don't have to remember to do it at the point of use. It will fix a swath of SVN 1.7 problems in one go. Its ok to double canonicalize things. SVN 1.7 still fails, still not worrying about that.

| * git-svn: add join_paths() to safely concatenate pathsMichael G. Schwern2012-08-021-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Otherwise you might wind up with things like... my $path1 = undef; my $path2 = 'foo'; my $path = $path1 . '/' . $path2; creating '/foo'. Or this... my $path1 = 'foo/'; my $path2 = 'bar'; my $path = $path1 . '/' . $path2; creating 'foo//bar'. Could have used File::Spec, but I'm shying away from it due to SVN 1.7's pickiness about paths. Felt it would be better to have our own we can control completely.

| * use Git::SVN{,::RA}->url accessor globallyMichael G. Schwern2012-08-021-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Note: The structure returned from Git::SVN->read_all_remotes() does not appear to contain objects, so I'm leaving them alone. That's everything converted over to the url and path accessors. No functional change. [ew: commit title] Signed-off-by: Eric Wong <normalperson@yhbt.net>
