2016-12-14i18n: add--interactive: mark patch prompt for translationLibravatar Vasco Almeida1-1/+10
Mark prompt message assembled in place for translation, unfolding each use case for each entry in the %patch_modes hash table. Previously, this script relied on whether $patch_mode was set to run the command patch_update_cmd() or show status and loop the main loop. Now, it uses $cmd to indicate we must run patch_update_cmd() and $patch_mode is used to tell which flavor of the %patch_modes are we on. This is introduced in order to be able to mark and unfold the message prompt knowing in which context we are. The tracking of context was done previously by point %patch_mode_flavour hash table to the correct entry of %patch_modes, focusing only on value of %patch_modes. Now, we are also interested in the key ('staged', 'stash', 'checkout_head', ...). Signed-off-by: Vasco Almeida <vascomalmeida@sapo.pt> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-10-27git-svn: do not reuse caches memoized for a different architectureLibravatar Gavin Lambert1-1/+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.

2016-01-26git-svn: fix auth parameter handling on SVN 1.9.0+Libravatar Eric Wong1-2/+6
For users with "store-passwords = no" set in the "[auth]" section of their ~/.subversion/config, SVN 1.9.0+ would fail with the following message when attempting to call svn_auth_set_parameter: Value is not a string (or undef) at Git/SVN/Ra.pm Ironically, this breakage was caused by r1553823 in subversion: "Make svn_auth_set_parameter() usable from Perl bindings." Since 2007 (602015e0e6ec), git-svn has used a workaround to make svn_auth_set_parameter usable internally. However this workaround breaks under SVN 1.9+, which deals properly with the type mapping and fails to recognize our workaround. For pre-1.9.0 SVN, we continue to use the existing workaround for the lack of proper type mapping in the bindings. Tested under subversion 1.6.17 and 1.9.3. I've also verified r1553823 was not backported to SVN 1.8.x: BRANCH=http://svn.apache.org/repos/asf/subversion/branches/1.8.x svn log -v $BRANCH/subversion/bindings/swig/core.i ref: https://bugs.debian.org/797705 Cc: 797705@bugs.debian.org Reported-by: Thierry Vignaud <thierry.vignaud@gmail.com> Signed-off-by: Eric Wong <normalperson@yhbt.net> Tested-by: Thierry Vignaud <thierry.vignaud@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-11-10git-svn: improve rebase/mkdirs performanceLibravatar Dair Grant1-8/+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>

* svn-maint-fixes: Git::SVN::*: avoid premature FileHandle closure git-svn: fix localtime=true on non-glibc environments
2015-02-26Git::SVN::*: avoid premature FileHandle closureLibravatar Kyle J. McKay2-0/+11
Since b19138b (git-svn: Make it incrementally faster by minimizing temp files, v1.6.0), git-svn has been using the Git.pm temp_acquire and temp_release mechanism to avoid unnecessary temp file churn and provide a speed boost. However, that change introduced a call to temp_acquire inside the Git::SVN::Fetcher::close_file function for an 'svn_hash' temp file. Because an SVN::Pool is active at the time this function is called, if the Git::temp_acquire function ends up actually creating a new FileHandle for the temp file (which it will the first time it's called with the name 'svn_hash') that FileHandle will end up in the SVN::Pool and should that pool have SVN::Pool::clear called on it that FileHandle will be closed out from under Git::temp_acquire. Since the only call site to Git::temp_acquire with the name 'svn_hash' is inside the close_file function, if an 'svn_hash' temp file is ever created its FileHandle is guaranteed to be created in the active SVN::Pool. This has not been a problem in the past because the SVN::Pool was not being cleared. However, since dfa72fdb (git-svn: reload RA every log-window-size, v2.2.0) the pool has been getting cleared periodically at which point the FileHandle for the 'svn_hash' temp file gets closed. Any subsequent calls to Git::temp_acquire for 'svn_hash', however, succeed without creating/opening a new temporary file since it still has the now invalid FileHandle in its cache. Callers that then attempt to use that FileHandle fail with an error. We avoid this problem by making sure the 'svn_hash' temp file is created in the same place the 'svn_delta_...' and 'git_blob_...' temp files are (and then temp_release'd) so that it can be safely used inside the close_file function without having its FileHandle end up in an SVN::Pool that gets cleared. Additionally the Git.pm cat_blob function creates a bidirectional pipe FileHandle using the IPC::Open2::open2 function. If that handle is created too late, it also gets caught up in the SVN::Pool and incorrectly closed by the SVN::Pool::clear call. But this only seems to happen with more recent versions of Perl and svn. To avoid this problem we add an explicit call to _open_cat_blob_if_needed before the first call to SVN::Pool->new_default to make sure the open2 handle does not end up in the SVN::Pool.

2015-02-26git-svn: lazy load some modulesLibravatar Eric Wong4-14/+19
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 gives a tiny reduction in syscalls (from 15641 to 15305) when running "git svn info" and counting via "strace -fc". Further, more invasive work will be needed to noticeably improve performance.

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.

2014-10-24git-svn: reload RA every log-window-sizeLibravatar Eric Wong1-8/+13
Despite attempting to use local memory pools everywhere we can, (including our call to SVN::Ra::do_update and all subsequent reporter calls), there does not appear to be a way to force the Git::SVN::Fetcher callbacks to use a pool other than the per-SVN::Ra pool. Git::SVN::Fetcher ends up using the main RA pool which grows monotonically in size for the lifetime of the RA object. Thus the only way to free that memory appears to be to destroy and recreate the RA connection for at every --log-window-size interval. This reduces memory usage over the course of fetching 10K revisions using a test repository created with the script at the end of this commit message. As reported by time(1) on my x86-64 system: before: 54024k after: 28680k Unfortunately, there remains some yet-to-be-tracked-down slow memory growth which would be evident as the `nr' parameter increases in the repository generation script: -----------------------------8<------------------------------ set -e tmp=$(mktemp -d svntestrepo-XXXXXXXX) svnadmin create "$tmp" repo=file://"$(cd $tmp && pwd)" svn co "$repo" "$tmp/wd" cd "$tmp/wd" if ! test -f a then > a svn add a svn commit -m 'A' fi nr=10000 while test $nr -gt 0 do echo $nr > a svn commit -q -m A nr=$((nr - 1)) done echo "repository created in $repo" -----------------------------8<------------------------------ Signed-off-by: Eric Wong <normalperson@yhbt.net>

2014-10-24git-svn: only look at the root path for svn:mergeinfoLibravatar Jakob Stoklund Olesen1-16/+13
Subversion can put mergeinfo on any sub-directory to track cherry-picks. Since cherry-picks are not represented explicitly in git, git-svn should just ignore it. Signed-off-by: Jakob Stoklund Olesen <stoklund@2pi.dk> Signed-off-by: Eric Wong <normalperson@yhbt.net>
2014-10-24git-svn: only look at the new parts of svn:mergeinfoLibravatar Jakob Stoklund Olesen1-12/+72
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.

2014-06-06Merge branch 'mm/pager-less-sans-S'Libravatar Junio C Hamano1-1/+1
Since the very beginning of Git, we gave the LESS environment a default value "FRSX" when we spawn "less" as the pager. "S" (chop long lines instead of wrapping) has been removed from this default set of options, because it is more or less a personal taste thing, as opposed to others that have good justifications (i.e. "R" is very much justified because many kinds of output we produce are colored and "FX" is justified because output we produce is often shorter than a page). Existing users who prefer not to see line-wrapped output may want to set $ git config core.pager "less -S" to restore the traditional behaviour. It is expected that people find output from the most subcommands easier to read with the new default, except for "blame" which tends to produce really long lines. To override the new default only for "git blame", you can do this: $ git config pager.blame "less -S" * mm/pager-less-sans-S: pager: remove 'S' from $LESS by default
2014-05-07pager: remove 'S' from $LESS by defaultLibravatar Matthieu Moy1-1/+1
By default, Git used to set $LESS to -FRSX if $LESS was not set by the user. The FRX flags actually make sense for Git (F and X because sometimes the output Git pipes to less is short, and R because Git pipes colored output). The S flag (chop long lines), on the other hand, is not related to Git and is a matter of user preference. Git should not decide for the user to change LESS's default. More specifically, the S flag harms users who review untrusted code within a pager, since a patch looking like: -old code; +new good code; [... lots of tabs ...] malicious code; would appear identical to: -old code; +new good code; Users who prefer the old behavior can still set the $LESS environment variable to -FRSX explicitly, or set core.pager to 'less -S'. The documentation in config.txt is made a bit longer to keep both an example setting the 'S' flag (needed to recover the old behavior) and an example showing how to unset a flag set by Git.

2014-04-17SVN.pm::parse_svn_date: allow timestamps with a single-digit hourLibravatar RomanBelinsky1-1/+1
Some broken subversion server gives timestamps with only one digit in the hour part, like this: 2014-01-07T5:01:02.048176Z Loosen the regexp that expected to see two-digit hour, minute and second parts to accept a single-digit hour (but not minute or second).
